HOPAS (Hybrid online policy adaptations strategy) on OPS-SAT

While AI technologies have shown promise in various applications in the space industry, their adoption within spacecraft flight software has yet to happen in a significant manner. This is due to a number of factors, including the relatively low computing power available onboard traditional spacecraft, the long development process required in the industry and the lack of opportunities for in-orbit demonstrations. In ESA's OPS-SAT satellite, Airbus teams identified a unique opportunity to quickly test promising algorithms in orbit as the industry seeks to resolve the issues listed above.

Small Satellite Missions to Mars – S2M2

The aim of this study was to investigate potential small mission architectures that would further ESA's exploration objectives at Mars post-Mars Sample Return (in the 2030s) or potentially in parallel with MSR (if sufficiently low cost).

Mars Surface Platform Capabilities Study

The Mars Surface Platform Capabilities Study aimed to provide ESA with an assessment of the state of the art in Mars lander technologies using ESA/European technologies with flight heritage. Airbus’ Mars lander experience is taken from the Beagle 2 probe launched in 2003 on board Mars Express.

The objectives of the study were to:

Preliminary design of on-orbit manufacturing of large antenna reflectors

This study aims to carry out the conceptual design of a large-parabolic-antenna reflector that is manufactured and assembled on-orbit.

Through its Clean Space initiative, ESA has been devoting an increasing amount of attention to the environmental impact of its activities, including its own operations as well as operations performed by European industry in the frame of ESA programmes. In its Technology Strategy, ESA identified 'Inverting Europe’s contribution to space debris by 2030' as one of the four technology development targets.

Impact of controlled and semi-controlled re-entry on Spacecraft design

There is increased attention being given to safeguarding Earth's orbital environment, as reflected by the number of relevant regulations that are being set forward by national governments and international organisations. Among others, ESA has published a Space Debris Mitigation Policy for Agency Projects (ESA/ADMIN/IPOL(2014)2), supported by the corresponding ESA Space Debris Mitigation Compliance Verification Guidelines (ESSB-HB-U-002).

High-Altitude pseudo-satellites for telecommunication and complementary space applications

The interest in HAPS is increasing in many areas, from military and security to commercial services. On the telecommunications side, HAPS are seen as relays to provide internet services worldwide, and as a possible complement to satellites. On the Earth observation side, the near-space location of the HAPS enables new services or could improve the existing satellite ones. From the satellite or from the HAPS market sides, it is important to understand how both systems can offer complementary services, and what the possible synergies between them are.

System impacts of propulsion Passivation

Propulsion passivation is most of the time feasible for running missions, using thrusters and existing AOCS modes, whatever the number of tanks and for both monopropellant and bipropellant systems.
For monopropellant systems the propulsion passivation may be:
-Partial for tank(s) with membrane. All the hydrazine under the membrane may be depleted but the pressurant gas above the membrane cannot be depleted. The final tank pressure is close to typically 5 bars at the end of mission.
