Title: CubeSat and NanoSat Technology
Post by: TrevorMonty on 07/09/2014 10:04 AM
What has surprised me is the lack of CubeSat and NanoSat threads so I thought it was about time to address this.
Plan is keep it something like the 3D printing threads where members post interesting links and keep the discussions to minimum or better still create discussion thread and maybe mission one. Please don't SpaceX this thread.

Cubesats make great test beds for new technologies some of which will work there way up into larger space craft.

Up to now cubesats have been legless and restricted to LEO, that is about to change.
A few companies and universities are working on propulsion systems for cubesats. These will give the cubesats wings allowing them to go BLEO and onto the outer planets in the next few years.
 
Here are just a few of the many being developed or already flight ready.

There's also our MIDAS (Multi-purpose Interplanetary Deployable Aerocapture System) project to do a deployable Magnetoshell Aerocapture coil combined with deep space comms and a 1-3m^2 roll-out solar array. It's only deceleration propulsion, but if we can make it work, it'd allow a 6U cubesat sized object to capture into orbit around another planet--that's a ~1000m/s delta-V maneuver performed in under 5min...

The Prox-1 is actually a Microsatellite which launches a cubesat as a target to focus on. In this case the target cubesat will be Planetary Society's LightSail experiment.
The Prox-1 is designed to lock onto a item in space and orbit. Just the technology for close up surveys of asteriods, some these students might find themselves working for Planetary Resources one day.

2) ULA ride sharing technologies. The MULE at 0:41 is SEP ESPA capable of delivery its cargo to Mars.
Amazing how many places they can find on 2nd stage to place rideshare payloads.
3) Interorbital small sat launcher.

Great article by Jeff on using Cubesats for Lunar missions.

The SLS 2017 lunar flyby demo could deploy quite a few Cubesats as secondary payloads. Looks like NASA is trying fill these secondary payload slots with interesting experiments/missions. Between Cubesats and the new small landers being developed for Lunar Xprize, a medium LV eg F9 could deliver multiple missions to moon in one launch.

A small cubesat lunar hopper would be ideal in exploring lava tubes. Land a small lander (eg moon express) near the lava tube entrance then deploy multiple hoppers each one building on the last ones flight, they could also be used as communications repeaters.

From the standpoint of custom phonesat implementations there is a significant software automation-set for phone design with virtual and hardware in the loop simulation.  You can change the frequency, the modulation, the codes, the operation modes (act not just as a client but as a peer to peer or even as a base station), bandwidth, etc.  Modern phones use direct convert digital to and from RF.  Meaning there are no limitations other than a top frequency of the converters used.

This means that new designs using latest components can be rapidly used and designed and built in less than 6 months.

History for UK small satellites. A couple of interesting applications for cubesats from 38 minute mark.
 
1) Attach a cubesat to debris and deploy a sail to add drag and deorbit it. I'm sure NASA would be happy to provide free secondary payload slots for these cubesats.

2) Build a large mirror from lots of small mirrors mounted on cubesats flying information. This is the idea of using constellations to do the job of a large expensive satellite. Doesn't matter if the cheap not so reliable cubesat fails as there is a spare wait in orbit.  Would be interesting to know if this technique could be used to replace something like the Hubble. Last I heard the James Webb was going to cost 8.8B, that can buy and launch a lot of cubesats.

It is a software defined radio.  They have been since about 2002.  The hardware RF capabilities have increased such that the top freq it is capable of has reached 10GHz to be usable in some European markets.

Edit; P.S. The new hardware dosn't even have a pre-amp or RF out amp anymore.  No real RF circuit tuning dificulties other than careful circuit board line draw policies to limit RF crosstalk which is part of the software package that designs the boards for you.

Micro Reentry Capsule 2 (MIRKA2) is a two segment nanosatellit reentry mission.
The cubesat is planned to be launched by the Canadarm2 from the ISS.
An experimenal pulsed plasma thruster (PPT) engine deorbits the system to separation altitude of 125km.
During separation the capsule gets accelerated and descends faster into the atmosphere.
During reentry several detectors measure the ablation behavior of the experimental heat shield.

One the points I best liked about Jurvetson's presentation was his point that having an audacious long-term goal often focuses you on making nearer-term design decisions differently than if you only had short-term goals. For instance, SpaceX's obsession with reusability isn't just about near-term decreased costs for satellite launch, but because of its long-term Mars ambitions.

There's the counter-risk that you'll make bad decisions based on incomplete information about a long-term vision. But I agree with him, that in some cases having that more ambitious long-term goal focuses you in a way that allows you (if you can make it through to product) to leapfrog past your competition. If you're the one company in the world with a highly reusable first stage (that took a few crashes to get perfected), it may be a huge benefit that will take your competitors years to catch up on.

One of the attributes of the CubeSAT industry is that everything is planned but nothing flies and works. Or at least, it seems that way.

I have gotten into long discussions about plans for using such and such a technology until someone realizes that the technology has never flown and worked on a CubeSAT, although all parties assumed that it was proven hardware.

Cubesat Formation flying demonstration mission. This mission has 2 cubesats, one is carrying a sunshade and is flown 20 m in front of 2nd cubesat which has a telescope to record solar activity eg solar flares.

http://spacefellowship.com/news/art41653/nasa-creating-a-virtual-telescope-with-two-small-spacecraft.html

Formation flying has potential to use multiple cubesats to do the job of one larger more expensive satellite. The other advantage is being able to upgrade and expand incrementally as budget and technology allows.

In the example above they could add another cubesat with different sensor/ telescope to monitor different light spectrums.

NASA Skunkworks Team Designs Advanced New 'Dellingr' CubeSat

http://www.americaspace.com/?p=71570

An advanced new six-unit (6U) CubeSat is being designed by a NASA skunkworks team, for possible deployment from the International Space Station by January 2016. The CubeSat, named Dellingr after the god of the dawn in Norse mythology, will be developed and tested over the next year under a self-imposed deadline. The CubeSat will be able to accommodate agency-class science investigations and technology demonstrations at a lower cost than normal.

The development team is comprised of engineers and scientists from NASA’s Goddard Space Flight Center in Greenbelt, Md. Environmental testing is expected to begin in December; after testing is completed, the CubeSat will then be delivered to NASA’s Kennedy Space Centre in Florida, where it will be readied for launch to the International Space Station, possibly as early as January 2016.

Picasso CubeSat

The PICosatellite for Atmospheric and Space Science Observations (Picasso) CubeSat, designed to investigate the upper layers of Earth’s atmosphere.

Developed for ESA by the Belgian Institute of Space Aeronomy with VTT Finland and the UK’s Clyde Space, Picasso will measure the distribution of ozone in the stratosphere and profile the temperature of the mesosphere and the electron density in the ionosphere.

Just 30x10x10 cm in size, the CubeSat will use a miniaturised multispectral imager for atmospheric ‘limb sounding’ with the Sun as the light source, and a multineedle ‘Langmuir probe’ sampling the electron density of the space around it.

CubeSats are standardised pico- and nanosatellites formed in cubes of 10 cm per side, with a maximum mass of 1.5 kg per cube, intended to make access to space affordable for small companies, research institutes and universities. One-, two- or three-cube CubeSats are currently being flown.

Picasso is one of a number of CubeSat missions being backed by the In-Orbit Demonstration element of ESA’s General Support Technology Programme. It will be launched in 2016 as part of QB50, a network of 50 CubeSats to probe largely unexplored layers of Earth’s atmosphere.

New company claims to be have new cubesat scale electric propulsion ready. It seems that MIT iEPS (ion Electrospray Propulsion System) is ready for commercialization. Here is the company web http://www.accion-systems.com/ (http://www.accion-systems.com/).

The founders came from MIT iEPS project - http://web.mit.edu/aeroastro/labs/spl/research_ieps.htm (http://web.mit.edu/aeroastro/labs/spl/research_ieps.htm)

To be honest, their approach seems to be better suited for attitude control applications than main propulsion. But they really impressed me with their fuel - non-toxic, liquid ionic liquid. The main advantage is that is is very easy to get ions, so no "heating stage" is needed. Thus the "engine" is very compact.

Their initial unit (MAX-1) has 2000s ISP, 0.2U form factor, 5W input power, 60% efficiency, 120uN thrust.

Finally listened to this podcast about solar sails.

At end the presenter mentioned couple of future technologies.

 1) lite weight flexible solar panels/sails that could produce 100s watts for a cubesat.
2) use a solar sail as solar concentrator for the cubesat solar panels.

Both of these would be ideal for cubesat missions going to outer planets eg Jupiter.

As someone that has been advocating the use of large solar concentrators with solar cells designed for concentrated sunlight (as opposed to the one foot dia. or so concentrators currently used with such cells on some comsats) for over a decade, it is very gratifying to hear that someone is finally proposing this.
Concentrator cells have achieved over 40% efficiency at up to 900 Suns so the total power available to a cubesat might be even higher than thought. A 32 sq. meter concentrator might not have much more mass than the solar sail mentioned above - particularly since a few hundred Suns is less difficult to achieve than the thousands of Suns for solar furnaces. A concentrator of this size and 90% reflectivity would focus about 11.7 KW thermal in LEO and at 40% efficiency concentrator PV would produce nearly 4.7 KW elec. although a cooling system would be needed.
Concentrator mass can be further reduced as can solar sail mass by cutting holes smaller than the wavelength of visible light to cut their mass by perhaps a factor of ten. Even current tech at 17 KW/kg thermal is competitive with nuclear at Saturn's distance IMO.

The link is dead.
The "C3" noted above is missing its numeric value.
Nanosats suffer from radiation in Earth orbit. Jupiter's environment would be a stretch to say the least.
Then there is generating power at 5AU where the solar irradiance is 4% of that near Earth.
Then there is communicating over that distance with that constrained power.
A few challenges To say the least.

Power generation may turn out to be the biggest issue in flying Cubesats far out, as many of the other problems could be solved by just adding more power! (insert Jeremy Clarkson joke here).

It gets also very cold and cubesat shape (10cm cube at least) contains too little structure to retain heat. Could get too cold very quickly in malfunction situations.

There are solutions, though.

CubeProbes are likely to need light weight mirrors to reflect the weak sunlight onto their solar panels.

Fortunately in a 6U device there is more room for insulation.
Title: Re: CubeSat and NanoSat Technology
Post by: mtakala24 on 03/29/2015 10:33 PM
Yes, 6U is one solution. Another is to not actually follow Cubesat sizes, but to build it somewhat bigger than 1U in every direction, still enjoying the benefits of being a NanoSat.

One other is to have CubeProbe with a pretty short lifetime, deployed just in time from a main probe.

You are correct.

I am simply pointing out the direction in which things are heading. A 9U FlatSat would also have the advantage of lower mass for structure; assuming 1U for avionics, 1 or 2U for propulsion, and the rest would be available for instruments. Moreover, a FlatSat may allow surface mounted solar panels that could eliminate the requirement for deployable arrays.

As for the costs of a dispenser, this would be a one time development expense, rather than an ongoing expense; as the founder of a company that makes dispensers, I can tell you that such expenses are not overwhelming.

Honestly at this point I think the topic of nanosats & microsats is starting to deserve its own forum.

We're now (last year) launching more than a hundred cubesats a year.  With mass-deployment mechanisms in planning, and a whole market in microsat launchers scheduled to sink or swim in the next five years, a thousand cubesats a year is not far in the future.  With that many projects, substantial commonality exists, so there is room for threads on specific parts as well as individual missions and programs.

What it is not is a simple extension of the ISS.

That is a $100 million dollar launch market. Definately grown up.

Launch costs of a 1U cubesat is (or was) $100,000.
Expect ~1000 launches a year within 5 years.

$100,000 * 1,000 = $100 million/year

3U cubesats cost about 3 times as much to launch.
Designing and making the cubesats will at least double the cost again.

Somehow, I don't think the CubeSAT community is going to pony up $100 million  5 years from now to pay for launches, unless the government starts deploying CubeSATs en masse as operational spacecraft.

Of course, there are several rocket companies with business plans that assume large numbers of paying CubeSAT companies, but the inevitable market process is probably going to winnow out all but one or two major providers, who may launch a handful of times per year for dedicated CubeSAT launches.

The term "flatsat" is already in use.

It refers to a prototype or engineering testbed where the innards of a satellite are are laid out flat, so they are easy to access and work on.

This does not affect your argument for a 9U configuration, although I have seen no development efforts agreeing with that.

Here is a more detailed paper on the Cubesat to laser communications test.

http://www.spacesymposium.org/sites/default/files/downloads/R.Welle_31st_Space_Symposium_Tech_Track_paper.pdf

They are targeting a downlink speed of 50Mb/s from a 600km orbit, with a transmission window of 3 minutes on each pass/orbit. That is 1.1Gbytes with usual transmission frame overheads should still be about 1GB per pass or 100 10MB pictures. They are hoping for transmissions rates up to 200Mb/s. If this works a single cubesat could download 100s-1000s of high quality pictures each day.

A network of dozens of earth stations would enable a cubesat to download 10sGB per orbit assuming it has power (read article). I can see a global network of earth stations being recreated to service 1000s of satellites. If satellite can't use a earth station because it clouded out or busy it just downloads at next free station. Each station would forward the received data to owner of satellite via web.

Assume $3 a picture and 1000 a day per cubesat that is $1M a year. At $100,000 to build then another $400,000 (RocketLab) to launch a 6U cubesat, the payback period is 6 months.
Who is going to pay $3 a photo, at $1000 per year for daily photo (weather permitting) farmers. 24 photos a day  for a forestry, $72 a day is cheap insurance to enable a forest fire to be spotted within an hour of it starting.

You can add Arduino shield with battery and USB input (such as http://www.seeedstudio.com/depot/Solar-Charger-Shield-v22-p-2391.html ) and connect it with USB solar charger of your choice (there is quite a selection of these). I have not found any that would "look like" a cubesat solar panel though.

Spire expanding their ground station network.

Spaceflight also announced partnerships with three other companies. Tethers Unlimited, BitBeam and Syrlinks will manufacture spacecraft radios designed to be “immediately compatible” with the network of ground stations. Those radios, Spaceflight said, are designed for cubesats but can also be used on larger smallsats. - See more at: http://spacenews.com/spaceflight-networks-and-spire-partner-on-smallsat-ground-network/#sthash.yEf3yIAs.dpuf

http://spacenews.com/spaceflight-networks-and-spire-partner-on-smallsat-ground-network/

There is definitely a bottleneck with downloading data from all the new cubesats and smallsat constellations that are going up, this network of ground stations should help. Between the radios and ground stations Spire has just made it a whole lot easier for new businesses using cubesats.

Long term Spire might end up making more money from their ground network than their satellites.

Cubesats missions to demo Optical communications to ground station.

http://spacenews.com/aerospace-corp-is-thinking-big-on-small-satellites/

The Optical Communications Satellite Demonstration was Aerospace’s first NASA project. It was designed initially to demonstrate that cubesats could transmit data at a rate of five megabits per second to a ground station with a 30-centimeter diameter antenna. Now, the Aerospace team expects the satellites to transmit 200 megabits of data per second. “It’s not a whole lot more difficult to hit 200 megabits per second than it is to hit five,” Welle said. “So that’s what we are aiming for.”

Aerospace delivered the first Optical Communications Satellite Demonstration spacecraft to NASA in March. That satellite is scheduled to launch in August as a secondary payload on a United Launch Alliance Atlas 5 rocket carrying a National Reconnaissance Organization payload.

NASA Deploys Satellite Designed to Re-enter Atmosphere Using Revamped Drag Device

http://www.nasa.gov/ames/nasa-deploys-satellite-designed-to-re-enter-atmosphere-using-revamped-drag-device/

NASA mission controllers confirmed that a small satellite launched from the International Space Station at 5:30 p.m. PST on Tuesday, March 3, has successfully entered its orbit, setting the stage to test technology that could enable rapid return of payloads from space. Over the next four weeks, the TechEdSat-4 satellite will deploy a second-generation exo-brake, an aerodynamic drag device, to perform a maneuver that will cause the satellite to de-orbit and re-enter Earth's atmosphere.

"The exo-brake is a self-stabilizing exospheric deorbiting mechanism that will allow us to return a payload to Earth fairly rapidly from an orbital platform, like the International Space Station," said Marcus Murbach, the TechEdSat-4 principal investigator at NASA's Ames Research Center in Moffett Field, California. "We were able to send commands and receive data to and from the satellite via the onboard modem using only a laptop and email account. This capability may greatly benefit the entire nanosatellite community."

About 30 minutes after the Nanoracks CubeSat Deployer jettisoned it from the space station, the autonomous free-flying satellite powered on. At approximately 8 p.m., the spacecraft received a command via email and deployed its specially-designed parachute-like exo-brake, which operates as a passive drag device at the extremely low pressures found at the top of the atmosphere. Engineers also confirmed the satellite has demonstrated new satellite-to-satellite communications technologies to provide precise information about the spacecraft’s health and position. TechEdSat-4 arrived at the station aboard Orbital ATK’s Cygnus spacecraft July 16, 2014.

This ESA satellite network maybe of use to earth observation cubesats.
Sending their data via GEO relay satellites maybe a better way than direct to earth. Communications to relay satellites is more reliable, no weather interference, plus a relay satellite should be in view 100% time. Data can be download in realtime if needed.

This is just one of many of the shelf CubeSat spacecraft being developed or currently available. They are bit like a smartphone, provide everything, power, processing, navigation, propulsion, power and communications. As a customer all you do add your payload/app and find a ride. Not sure about communications with this LunarCube but I think they provide communications as well, at an on going fee I suspect.

Lunar orbital and asteroid missions just got a whole lot easier and a more affordable.

Busek, in partnership with Morehead State University (MSU), is developing a versatile 6U CubeSat platform nicknamed “LunarCube” that can undertake missions beyond LEO. The spacecraft can host a variety of science payloads, and its mission capability is highlighted by >3km/s of delta-V maneuverability with a groundbreaking ion propulsion system heretofore unavailable to CubeSats. Salient features of this propulsion system include innovative use of solid iodine propellant and a 60W class mini RF ion thruster that is capable of 1.3mN thrust and 3250sec specific impulse (Isp). The primary objective of the LunarCube program is to support a deep space CubeSat mission to the Moon from GEO or a translunar trajectory (such as the SLS/EM-1 drop-off) and carry out a lunar science campaign as a technology demonstration of the platform. A secondary objective is to showcase that much of the spacecraft’s miniaturized avionics and power system can survive the harsh radiation environment. The LunarCube concept, especially its ion propulsion element, has received significant attention from the CubeSat user community targeting near-term lunar flights. In fact, the platform has already morphed into an EM-1 CubeSat mission known as “Lunar IceCube”, selected for flight by NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program.

Technology demonstrator for self-deploying telescope. Another great use of cubesats for demonstration mission.   
Besides being a demo it may also result in a totally new way of creating large satellites from cubesats.

If it's taken 15 years to develop, and we expect a decade's worth of results out of it, shouldn't we already be working on its replacement now?
It is kind of being worked on. http://www.popsci.com/darpa-wants-robot-port-in-space

Note that the concept is scalable, you could build arbitrarily large scopes like this, consisting of multiple launched payloads.

The CATS plasma thruster is getting funding from DARPA for flight demo. I've be hoping this propulsion system would fly, along with a lot of interplanetary scientists I'm guessing.

Surprisingly DARPA's interest is long endurance LEO flights, not BLEO.

http://www.parabolicarc.com/2015/11/25/phase/

Here is an older video on it.
Video from ISSC 2014.
First half of this video starting about 0:10 is on the CAT thruster. This is a plasma thruster for cubesats. With LEO to earth escape in 6months and DV of  up to 7km/s this propulsion system enables planetary missions using LEO launched cubesats.

http://www.ustream.tv/recorded/46819252

I assume that this case study either describes the DARPA's mission or was used to sell the CAT to DARPA.

"Station keeping and operational life extension for a CubeSat Earth observation mission."

Cubesat Lifetime without propulsion is 308 days.  The CAT can provide a claimed extra 3.7 years in a 400 km orbit. Use Xenon as propellant for high thrust or water for high Isp.

http://www.phasefour.io/assets/p4_case_study_1_leo_72115.pdf (http://www.phasefour.io/assets/p4_case_study_1_leo_72115.pdf)
Did you mean using Xenon for high Isp an water for high thrust?

UPDATE: I checked the source document, which really states that than Xe ISP is just 500s, three times lower than for water. This is strange.

It seems to me that there is an excess of supply in the market, compared with the number of missions intended to fly applications. It appears that applications developers still want to create their own platforms. Since we all live in a world where widespread adoption of standardized smartphone platforms like the IPhone and Android have encouraged developers to create applications, in our field the people who should be focused on applications spend their time making solar panels.

There is a standard for cubesats but currently not one for their 'payload bay'. A manufacture could write a user interface specification for the payload bay on their off the shelf cubesats.

They would have to specify maximum height, normal length and normal width, power available, connecting wires, cooling available, external holes for sensors, data connectors, data & message formats, data that the guidance system can supply such as time & location, commands available, data bandwidth to & from Earth and things like centre of gravity.

Swarm satellites.

Weighing in at just 4 grams, the Sprites are basically flying, solar-powered circuit boards about the size of a Triscuit cracker, carrying a radio transceiver and small sensors.

Future missions could pack swarms of tiny spacecraft like FemtoSats and Sprites inside CubeSats, which in turn would ride to another planet along with a larger spacecraft.

Appreciate the corrections - but isnt the exact form factor beside the point of functioning micropropulsion ?
Almasat-1 was the size of 6U, although it didn't follow the form factor. Wren was 1p PocketCube (https://en.wikipedia.org/wiki/PocketQube) which is about half the dimensions of 1U. CUSats were about 12U equivalent, but again different form factor.
ALICE - yes, appears to have been more of a component test, and no details published post launch.

My mistake only thinking 2D not 3D forgot the other 2 layers.

With these SunCubes and a few cubesats a planetary orbiter could use shotgun approach to sampling. Deploy a few cubesats which in turn would use SunCubes for expendable sensing missions. Each Cubesat could be loaded with a mix bag of SunCubes giving some redundancy especially if a Cubesat is lost. The SunCubes would do the sampling while Cubesat would act as comms relay to mother ship orbiter.

Two CubeSats Deployed from the International Space Station

Published on May 20, 2016
This movie of a CubeSat deployment from the International Space Station shows a compilation of photos taken by astronauts on May 16, 2016. The bottom-most CubeSat is the NASA-funded MinXSS CubeSat, built by the University of Colorado in Boulder. MinXSS observes soft X-rays from the sun. Such X-rays can disturb the ionosphere and thereby hamper radio and GPS signals. The second CubeSat is CADRE — short for CubeSat investigating Atmospheric Density Response to Extreme driving - built by the University of Michigan and funded by the National Science Foundation.

London pegged that number at 16 CubeSats ( equatorial orbit )for this demonstration. At a reasonable altitude, he said this number would provide the level of coverage the Army is seeking to prove at a targeted price point. He acknowledged that the halo would not cover a huge percentage of the Earth, but said that it would reach important areas of responsibility within U.S. Southern Command (USSOUTHCOM), Africa Command (USAFRICOM), and parts of Pacific Command (USPACOM).


Some of the challenges the Army faces in fielding this system are sufficient launch capability and operating a ground segment that can run demonstration satellites. Previously, the Army pursued it’s own launch system, the three-stage Multipurpose NanoMissile System (MNMS) program, as well as the JCTD Soldier-Warfighter Operationally Responsive Deployer for Space (SWORDS), but ultimately decided both were too expensive to continue. London said launching to an equatorial orbit remains a challenge, but expressed confidence that commercial systems such as Orbital ATK’s Pegasus and Virgin Galactic’s LauncherOne could possibly provide such a service for the military in the future.

Industry record: AstroTube, world's longest retractable cubesat boom system successfully deployed. Thanks to all who made it possible!
Background:
http://spaceflight101.com/pslv-c35/alsat-nano/

Quote
AstroTube is a test of the world’s longest retractable boom compatible with the CubeSat form factor. In this test flight, it deploys to a length of two meters and only occupies the volume of a packet of cigarettes when in its stowed configuration. Boom technology for small satellites is an important part for future passive deorbiting systems.

The boom system requires around 0.5U of volume and supports a high-precision deployment with an accuracy of +/-0.25 millimeters. The boom itself consists of composite material and allows for partial deployment without losing structural integrity. Possible applications of the boom are for payload deployment and retraction, solar panel and antenna deployment, and deorbit structures. Because the boom is deployed with a motor and does not have any stored energy, its deployment will avoid any shocks to the satellite structure and its instruments.

A scaled-up version of the boom design known as AstroTube Max can support lengths of 12 meters.

When the cube opens, an antenna pops out and its ribs extend from a canister to spread out a golden mesh. The RainCube antenna has to be small enough to be crammed into a 1.5U container (1U, a CubeSat unit, is roughly equivalent to a 4-inch cubic box, or 10 x 10 x 10 cubic centimeters).

Accion Systems ion thruster. I've covered this thruster elsewhere this thread.

Watch "TMRO:Space - The small Ion thruster that could change space travel  - Orbit 10.14" on YouTube
https://www.youtube.com/watch?v=R8cX5-xq2Zo

These small thrusters would also allow cubesats to operate at lower altitudes giving better imaging and reducing end off life deorbit to months.

A second study involves a new generation of CubeSats that take advantage of in-situ resources -- living off the land -- while exploring space. The proposal combines existing CubeSat technology with 3-D printing technology and an in-situ resource utilization (ISRU) water extraction system. The 3-D printing technology enables development of steam thrusters, as well as tanks that fit within the available space within the CubeSat. The ISRU module captures and extracts water, and takes advantage of the heat generated by the CubeSat electronics system, with supplemental power from solar charged batteries.

NASA Set To Launch Shoebox-sized Satellite Studying Earth's Upper Atmosphere

NASA Goddard
Published on Aug 2, 2017

NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days from launch, they are confident the shoebox-sized satellite Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science. Dellingr will study how the ionosphere, a region in Earth’s upper atmosphere, interacts with the Sun. Before launch, Dellingr is required to visit the Magnetic Test Facility at NASA Goddard to test the spacecraft’s magnetometers - key instruments for measuring the direction and strength of the magnetic fields that surround Earth. The spacecraft is scheduled to launch this August aboard a SpaceX Falcon 9 rocket to the International Space Station where it will be deployed later into a low-Earth orbit.

Planet are testing new proplusion system on their Doves.

The nano propulsion system is known as Indium Field Emission Electric Propulsion. This propulsion system consists of a 250-gram cylinder of indium, associated heaters, ion generator mechanism, and beam neutralizer mechanism. Thrust is generated by the acceleration of ions via an applied electric field between an emitter crown and extractor electrode. The expected thrust is 350 micro-Newtons (uN), and there is a total of 5000 Newton-second total impulse capability for up to 1415 m/s velocity change for the 5 kg Dove Turbo satellite.

By the way, Minotaur will be launching another 6 SkySats on October 31st with operational "Green Propulsion" aka ECAPS HPGP or LMP-103s. That is, a fully flight tested substitute for hydrazine monoprop, in commercial use.

Those will join an existing constellation of SkySat-3 through 7, which have accumulated significant on orbit life now.

In December 2016, SkySat-7 experienced a thrusters firing anomaly, which was quickly resolved by a software change.

This SpaceNews Article (http://spacenews.com/hydrazine-ban-could-cost-europes-space-industry-billions/) where Arianegroup sounds the alarm bell about the possible Hydrazine ban.
I'm sorry Arianegroup you should just invest some more in thruster development!

The article is contradiction with Bradford ECAPS (http://ecaps.space/). And there is also LMP-106, and the USA one. (It's true these have to be pre heated.)
And lets not forget HTP (that was competing with hydrazine form the start).
HTP - hydro carbon could be a replacement for toxic bi-propallent hypergolics. (Or Masten's MXP-351)

This was also a bit stupid in my oppinion: SpaceNews, Arianegroup .. smallsat standardisation... (http://spacenews.com/arianegroup-futurist-sees-smallsat-standardization-as-key-for-timely-launch/).
 ??? The larger segment is already standardized:
Cubesats 0.25-16U    (pocket cubes 1-4 P) [a loaded 12U/16U cubesat deployer ~32.5kg]
Here they have a point: ~30kg (or a 12/16U box); 50kg (or 100lbf/45kg); 75kg ; 100kg (or 90kg/200lbf)
ESPA (https://en.wikipedia.org/wiki/EELV_Secondary_Payload_Adapter) 15" ring; 180kg (400lbf)
ESPA Grande, 24" ring; 300kg (660lbf)

OneWeb sat's as well as SpaceX sat's will indeed become standard busses.
Let's add this chart I made with a list of small sat buses.
Indeed the NORSAT's were troublesome, but it's strange GLAVCOSMOS/ECM could launch them without trouble.
This post is a bit OT, you may want to move it to more appropriate thread.

Three  cubesat technology demo missions that are on Cygnus now.

Laser coms to earth.
Formation flying.
ISARA
"To the best of his knowledge, ISARA will be the first in-space demonstration of a reflectarray antenna as well as that of an integrated antenna and solar array. "

Not clear but I think array is etch to back of solar array. So back needs to face ground station. At 100Mps it is huge improvement over existing cubesat comms and best of all comes almost mass free with solar arrays.

I came across a device in my perusal of a electronics parts flyers.

TDK ICM-20602

This is a full 6 axis IMU sensor that is in a 3mmX3mmX0.75mm size in a 16 pin LGA,

Primarily this device would be for robotic end effectors and other robotic moving parts or motion sensing controller/phone devices. But it could also be used by Cubesats. The price is definitely right for school projects: $99 for the complete kit with board that has a MCU with built in debugger and software for programming a full up IMU in a size that would easily fit in a Cubesat.

This is the direction things are going in for such sensors. Although this sensor is not a LV quality sensor but for a Cubesat that can use GPS to keep it calibrated it would be good enough for most pointing applications.

The price is for a commercial kit for a commercial application in single quantity. Pointing accuracy though is still just +/-1% but for the low end Cubesat projects again having a full IMU capability vs none at all could make the project successful.

I do image there are more accurate IMU sensors of similar size and with MIL-SPEC ratings for significantly larger price but not any significance in form factor size.

The MagTag concept has few applications for cubesats but also any satellite or in space, especially persistent platforms.With something like this Lego satellites maybe real possibility.

If I understand it correctly its magnetic coupling which can can electrical connections and lower pressure fluids. Ideal for refuelling but may also be capable of cooling fluid transfer. Think it uses electromagnet to active and deactive magnetic couple, once coupled no power is needed.

0476-EX-CN-2018 AAReST

Quote
The AAReST mission has been developed to meet the goals and objectives above. The satellite is a prime
focus design (1.2 m focal length, 0.3°field-of-view) with the primary mirror divided up into a sparse aperture
consisting of an arrangement of 10 cm diameter circular mirrors. The primary mirror segments are attached to
a cluster of CubeSats, two of which are able to undock from the cluster and navigate independently. The
telescope would launch as a small secondary payload in a stowed state. The stowed volume of the telescope is
approximately 0.3 m x 0.4 m x 0.5 m. After separation from the primary payload, the telescope would deploy its
camera package at the end of a 1.2 m long hinged composite boom to the focus of the mirror array.

Using wavefront sensors, the deformable mirrors would be adjusted and calibrated in order to
minimize the size of the mirrors’ individual point spread function (PSF). The mirrors would not be co-phased
down to subwavelength levels, as would be required for a more advanced science mission, as this would require
an additional metrology system that is prohibitively expensive for a small mission such as this. Instead, images
would be taken to demonstrate the ability of the mirrors to self-correct their shape, as well as the ability to repoint
and correct the individual PSFs.

Once the initial calibration and imaging demonstration is completed, two of the mirror segments, which
are carried by independent CubeSats, would detach from the mirror cluster and then re-dock to the cluster in a
different configuration. This would demonstrate on-orbit assembly of the mirror segments. Once the cluster is
reassembled, the mirror calibration and imaging would be performed again in order to show the capability of
calibration in two mirror configurations.

Smallsat Launch U standard.

www.parabolicarc.com/2018/08/09/launch-unit-standards-announced-smallsats/

This sizing standard was to help simplify an lower launch costs for smallsat. Much same as U sizing standard has done for cubesats and containers for goods shipping.

Unlike cubesats smallsats come in lots of different shapes and sizes. The standard still allows for this but limits their outer dimensions for launch.
The physical limits are 45 cm x 45 cm x 60 cm and 60-80kg.

As long as they meet these standards and usual LV safety standards, switching between LVs at short notice shouldn't be issue.

I'll link to the article and the writeup in another thread once we've put our finishing touches on it, but it's relevant to this planetary/BLEO smallsats discussion--we were getting results suggesting you could use a LauncherOne (refueled on-orbit with a dry-launched/LEO-fueled storable biprop kick stage) to send an 90-450kg net payload almost anywhere in the inner solar system, out to Jupiter.

The alternative to refuelling is to deliver earth departure stage on separate flight, rendezvous in orbit and move satellite to earth departure stage. Mission complexity is not lot different, still need to rendezvous, just trade between swapping fuel and payload(satellite).

If done at an unmmanned robotic station, then robotic capabilities of station could help reduce risk. Checkout the satellite before sending BLEO or do minor repairs. The station would also allow for assembly of satellite, eg add large lite weight solar array built at station.

Smallsats and cubesats for planetary missions BLEO.

www.sciencemag.org/news/2018/08/tiny-spacecraft-are-breaking-out-earth-s-orbit

We just presented our paper (mentioned in the depot thread in this NSF category) on using micro depots to enable smallsat launch vehicles to do dedicated deep space launch. I'll link to the article and the writeup in another thread once we've put our finishing touches on it, but it's relevant to this planetary/BLEO smallsats discussion--we were getting results suggesting you could use a LauncherOne (refueled on-orbit with a dry-launched/LEO-fueled storable biprop kick stage) to send an 90-450kg net payload almost anywhere in the inner solar system, out to Jupiter.

The alternative to refuelling is to deliver earth departure stage on separate flight, rendezvous in orbit and move satellite to earth departure stage. Mission complexity is not lot different, still need to rendezvous, just trade between swapping fuel and payload(satellite).

If done at an unmmanned robotic station, then robotic capabilities of station could help reduce risk. Checkout the satellite before sending BLEO or do minor repairs. The station would also allow for assembly of satellite, eg add large lite weight solar array built at station.

First, in order to get a full stage in this case, you'd need a much bigger launcher--(LauncherOne payload to LEO is like 475kg, a fully-fueled LauncherOne stage is over 2500kg). Second, I really have a hard time believing swapping stages is going to be easier than propellant transfer. The Russians have been doing non-cryo transfer since long before I was born, and cryo transfer is only a little bit harder, but also rapidly increasing in TRL. But we should probably take more discussions on depots themselves over to the depot thread.

curious...so to do this would the stratolaunch airplane be "better"...two launches at "near the same time" one carries the payload and the other "prop"...or use launcher one and two launches at a short interval?

I am just asking?

GEO comms smallsat, no size given but Terran Orbital specialize in 10-100kg cubesat and smallsats. Being delivered direct to GEO by LV, which is unknown at present.

With likes of Made In Space and SSL working ways to add lite weight solar arrays and large radio reflectors in orbit.  Smallsats could make large in roads into GEO market. They are also getting their own range of dedicated LVs from 200-1250kg (LEO) some of which with right 2nd or 3rd stage could deliver few 100kgs direct to GEO.

It doesn't explicitly say the LV will put it in GEO (it's possible for a larger sat to carry smaller sats to GEO).  If it is going directly to GEO on the LV I'd guess it would be on a Russian rocket?  Who else really offers that?

Here is quote.  After reading it again not quite sure what they mean.

GapSat-1 will launch in the third quarter of 2020 directly into the geostationary arc 36,000 kilometers above the Earth, according to the company.

California state have commissioned pollution detecting 6U? cubesat that Planet will build and operate for them.
Not stated, but Planet may also do data analysis.

Cubesat water tanker demo mission.

spacenews.com/orbit-fab-to-test-refueling-technology-on-iss/

There are a few companies offering thrusters that use water, Tethers Unlimited and DSI to name two. I think both are flight ready if not flying. 

With in orbit refuelling not only can life of cubesat be extended it also opens up more mission options.
1) fly lower giving higher resolution images eg move from 500km to 250km doubles resolution. Cubesat deorbits in months in case of failure not years.
2) retrieval vehicles to remove debris and dead satellites.
3) have tankers stationed at higher orbits eg GTO or EML1 to allow cubesats to go BLEO without requiring much more than 2kms DV.
