Has anyone ever flown a CubeSAT with propulsion?
Read cyclop deployer articles above. I think one of smallsats its deploying is going to test some thrusters.

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.

SpinSat is using these solid thrusters I think.


Block of solid propellant.

SpinSat isn't a Cubesat.

Even if SpinSat is GOING to test CubeSAT propulsion, my point remains is that "everyone" thinks CubeSAT propulsion has been tested, but it hasn't.

There are a series of CubeSAT technologies that have been proposed, but have not successfully flown:

Tethers
Large solar arrays ( > 10 watts)

Even in cubesat world taking new technologies from the lab to flight still takes time and more importantly money.

Oh, yeah, but my point was and is that a lot of people assume that these technologies are proven, but not much has actually been flight proven.

Same with the ground station network, lots of talk, but no network, so comm is a real problem for CubeSATs.

But this is not a problem specific to cubesats. It happens all the time in all areas, if people assume something instead of doing recherches.

This webcast is about reducing the cost of space especially the expensive government satellites.
Discusses using lower cost smallsats and cubesats in LEO to replace some of the expensive higher orbit satellites.
Government space employees will like the hunting plan.

Solarpanels and web shop for PocketQubes. PocketQubes are 5cm square cube compared to 10cm for 1U cubesats.

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.

I am curious as to limitations for US CubeSAT operators to fly on Russian launch vehicles these days.

A few more hoops to jump through but still possible.  Who knows how it will change in the future though.

Do these fit into this category? They are 10x10x30 inches, and image the earth.

https://www.planet.com/

Two of them are going up with CRS-5, to add to an already existing cluster.

I believe those are centimeters, not inches. which makes them 3U CubeSATs.

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.

For those who care for CubeSats - i am trying to keep track of all cubsat missions on this page:

BTW: if you know of a cubesat mission, which is not yet on the list, please drop me a note.

Micro sat to do a asteroid flyby.

A SkyBox class satellite, ie about the size of a small refrigerator.
