The ASTERIA satellite, which was deployed into low-Earth orbit in November, is only slightly larger than a box of cereal, but it could be used to help astrophysicists study planets orbiting other stars.

On March 22th and 23th the second PocketQube Workshop was organised by TU Delft. Most of the presentations can be viewed on Alba Orbital youtube channel.

Some of the interesting stuff about pocketcubes.
At TU Delft they are developing a new PQ9 Interface standard. On the website of GauseSrl there are presentations from the 4th IAA University Satellite Missions & CubeSat Workshop. This presentation is about the PQ-9 interface standard.

Another interesting development from Delft University of Technology is the satellite component search engine:

It's explained in this presentation:

Dellingr-X’s all-important command and data handling and electrical power systems will be radiation tolerant;

This is a must for BLEO missions using  cubesats and smallsats.

We just saw the first launch of CubeSats into deep space!  MarCO A/B launched together with Insight on a flyby trajectory of Mars.  In addition to their pioneering path and operations, they are also demonstrating quite a lot of new tech for CubeSats--a deployable reflectarray antenna for high gain X-band communications (it's a passive phased array), a software defined radio capable of full communications with DSN, and a new cold-gas propulsion system.

Now that @NASA has shown the viability of auto X-ray navigation in space, plans are in work to include the tech on a CubeSat mission to the #Moon & engineers are now studying the possibly of adding the capability to human-exploration spacecraft.

The system works by detect X-ray emissions of pulsar stars, kind of like X-ray version of optical star tracker system.

During a panel session at the Space Tech Expo conference here May 23, executives with several propulsion startups said that the demands for propulsion that can meet mass, volume and power constraints of small satellites were helping drive innovation in this field.

Its nice to see this propulsion system fly, I've been following them for years, see earlier posts on CAT thruster.

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.

Developed under a Small Business Innovation Research contract from the US Army’s Space and Missile Defense Command, the SWIFT-KTX transmitter builds upon TUI’s high-maturity SWIFT software defined radio platform to enable satellites as small as a loaf of bread to transmit data at rates exceeding 100 megabits per second (Mbps).

I've been following TU and there HYDROS-C tbruster development for while, nice to see it fly. Can generate high thrust for very short time if need ie 1.5N for about 1sec before recharging its H and O gas storage by electrolysis of water. Most of time it would use lot lower thrust levels, but nice to have extra boost on tap if needed.
