The future, by the box: 10 years of ESA Technology CubeSats
Imagine building yourself a small satellite out of standardised 10-cm boxes. Such humble nanosatellites are called CubeSats, first devised as an educational tool but increasingly performing valuable work in space. ESA’s CubeSat Systems Unit has been utilising CubeSats for a decade now to test out innovative new technologies – resulting in seven missions to date with many more on the way.

ESA moves ahead with In-Orbit Servicing missions
Isn’t it strange that when satellites run out of fuel or a single component breaks down, we just discard them? ESA and European industry have joined forces to make sure that our satellites can live on.

Plato in ESA's LEAF room
Image:
This image shows ESA’s next exoplanet mission, Plato, in the Large European Acoustic Facility (LEAF). In this room, the noise of a rocket taking off is simulated. The large room measures 11 by 9 metres and is 16.4 metres high. One wall is equipped with multiple noise horns, that have a similar design as ordinary speakers. Nitrogen is shot through the horns and can produce noise up to 156 decibels. During tests, no one is allowed into the room that is surrounded by a 0.5-m-thick layer of concrete to keep the noise in. Plato passed its test with flying colours.
[ Image description : An engineer dressed in a blue lab coat and white hairnet looks upon the Plato’s structural model inside the LEAF chamber in ESA’s ESTEC Test Centre. Plato is put on top of a structure of four wheels. The LEAF room is green and has one wall with huge white holes in the wall. These holes are noise horns that can produce up to 156 decibels. The satellite is surrounded by microphones on sticks to measure the acoustic environment.]

Secrets of pearl harnessed for stronger space structures
Pearls and seashells are made from the same basic stuff as easily crushed chalk – humble calcium carbonate – so why are they so much tougher? Researchers are taking design tips from the micro-structure of these naturally formed materials to produce stronger, more fracture-resistant ceramics for future space missions.

Precision deployer to put Hera’s CubeSats into asteroid orbit
Dutch firm ISISPACE has manufactured more than 600 cereal-box sized ‘CubeSat’ satellites, plus nearly 200 deployment systems used to release them into orbit. Of all of these, the pair of Deep Space Deployers it has overseen for ESA’s Hera asteroid mission for planetary defence have been by far the most challenging. The two systems need to keep their nanosatellite cargo alive and healthy, before releasing them on a precisely staged basis – at a velocity of just a few centimetres per second. Any faster and Hera’s CubeSats would risk getting lost in space.

Compact electric thruster cleared for space firing
An innovative compact electric propulsion system has recently completed its extended qualification firing test campaign in space-representative vacuum and temperature conditions, leaving it ready to be deployed aboard the ESA-supported µHETSat technology demonstration microsatellite mission, slated for launch by the end of this year.

Printing electronics to help space missions lose weight
The functionality of any space mission is determined by its electrical, electronic and electro-mechanical (EEE) components. While individually small in size, a standard satellite can contain thousands of these active and passive devices, along with several kilometres of connective links ESA is looking into printing these electronics, to boost overall robustness while driving down mass, manufacturing lead times, and cost.

Exploration of space industry best practice
ESA is reaching out to members of the industrial space sector, particularly small and medium-sized enterprises (SMEs), to take part in a survey on lessons learned in the space industry.
