Growing fungi structures in space

The mushroom-forming fungi Pleurotus ostreatus (PO), Trametes versicolor (TV) and Schizophyllum commune (SC) are known to effectively colonise organic material. These fungi were grown on the aquatic fern Azolla filiculoides (AF), the fastest growing plant on Earth, and that can fix its own nitrogen. SC showed the best growth on AF. Therefore, growth of this fungus was determined under microgravity conditions and high radiation dosage (up to 200 Gy) and related to melanin production.

Game theoretic analysis of space debris removal dilemma

The increase of space debris means that active space debris removal is becoming more relevant. An active debris removal mission would have a positive effect (or risk reduction) for all satellites in the same orbital band. This leads to a dilemma: each space agency has an incentive to delay its actions and wait for others to respond. We model this scenario as a non-cooperative game between self-interested agents in which the agents are space agencies.

Quantum Metrology for Space-Based Tests of Gravitational Physics

This study aimed to develop a framework for studying the effects of spacetime curvature on the propagation of quantum states of light, and to compare them with the propagation of classical light. When distributing entangled photon pairs through a gravitational potential, the effect of spacetime curvature on the properties of quantum states can become significant. This could be relevant for plans to use satellites for global quantum key distribution.

APEL: Assessment of atmospheric optical Properties during biomass burning Events and Long-range transport of desert dust

The main scope of this activity was to foster the exchange of expertise between the European Lidar Network (EARLINET) and Latin America Lidar Network (LALINET), and demonstrate the capability of joint research, setting the groundwork for GALION (The Global Atmosphere Watch Aerosol Lidar Observation Network) and future calibration/validation of ESA’s atmospheric satellite missions such as Aeolus and EarthCARE.

Mission performance assessment for space science missions

The objective of this activity was to propose a general infrastructure of an end-to-end simulator (E2ES) for space science missions, namely an E2ES requirements baseline, reference architecture and an associated library of software models (building blocks, BB) to promote reuse, standardisation and reduction of engineering costs by defining a products/science validation process throughout the lifecycle based on an E2ES.

High Altitude Pseudo Satellites for Telecommunication and Complementary Space Applicaions (HAPPIEST)

The development of High Altitude Pseudo-Satellites (HAPS) has reached an outstanding level of maturity, with several flight demonstrations that augur soon to have operational capabilities. ESA, aware of the synergies among satellite and HAPS services, set up the HAPPIEST study to analyse the impact of the erruption of aerostatic HAPS into the telecommunications market, currently covered by space and terrestrial networks. Furthermore, some complementary payloads can serve interesting applications such as Earth observation and navigation services.

Reliable TT&C during superior solar conjunctions

The purpose of this study was to define the a communication subsystem architecture (including both ground and space segments, as well as operational methods) that allows robust RF TT&C links during superior solar conjunction phases. The defined architecture shall ensure robust and reliable links in scintillation regimes (i.e. at low SEP angles) where TT&C links are nowadays degraded, leading to occasional link interruptions. Similarly, the defined architecture shall ensure that at even higher scintillation regimes (i.e.

High efficiency 150 K Joule-Thomson cryocooler with an ejector

There is an increasing need for ever smaller pulse-tube coolers. These coolers have the characteristics necessary for space applications because the absence of moving parts in the cold finger makes them extremely reliable and any induced vibrations are typically smaller and easier to control.

But these types of cooler are less efficient and have a lower power density. Typically, this is resolved by increasing their drive frequency, to reduce amplitudes and displacements, which means that the coolers are smaller

Quantum Metrology for Space-Based Tests of Gravitational Physics

Testing the validity of general relativity at cosmological and microscopic scales is a challenging open question. The impediment at cosmological scales is our lack of understanding of dark matter and dark energy. At microscopic scales, it is the unknown effect of gravity on quantum mechanics. Recently, space-based matter wave interferometers have been proposed as candidates for addressing certain aspects of both these problems.
