AIM MASCOT-2 Asteroid Lander Concept Design

The MASCOT (Mobile Asteroid Surface Scout) lander onboard JAXA's Hayabusa 2 sample return mission to C-type Near Earth asteroid Ryugu is a lightweight (~ 10 kg) and compact (0.3 x 0.3 x 0.2 m3 ) landing platform with the capability to carry various in-situ experiments with a total mass of up to ~3 kg. Thus a system to payload mass ratio of 7:3 can be achieved.

Detection of microparticle impacts on spacecraft via their plasma effects

Microparticles are one of the most unknown components of the space environment. Their observation and investigation is complicated by their small size and their high velocity. When impacting on a spacecraft surface, a plasma cloud is generated by shock wave and surface ionization processes. This transient cloud of vaporized and ionized particle and surface material, referred to as impact plasma, rapidly expands to the meter scale within microseconds, thereby interacting with spacecraft surface components.

Assessment of Satellite Constellations for Monitoring the Variations in Earth Gravity Field “SC4MGV”

The overall objective of this study is to assess constellations of two pairs of satellites for the retrieval of time-variable gravity field information for best quality scientific monitoring of mass distribution and transport in the Earth system. Before embarking on this study the geodetic community and space agencies have come to realize that weaknesses in current single-pair gravimetric satellite missions such as GRACE or GRACE-FO (to be launched in 2017) would significantly be alleviated by having a second GRACE-type pair in space simultaneously.

Interplanetary Micrometeoroid Environment for eXploration (IMEX, NEMS)

The approach of the ‘Interplanetary Meteoroid Environment for eXploration’ (IMEX) project is to build a model of meteoroid streams throughout the inner solar system. Our motivation for this model is the impact hazard to spacecraft. An understanding of the interplanetary environment, including the dust environment, is crucial for the planning of spacecraft missions in the inner solar system. Particles striking a spacecraft with high velocities can cause damage leading to the impairment or even failure of the spacecraft or its subsystems.

Perspective of Solar Pumping of Solid State Lasers for ESA Missions

The use of lasers for space missions has been increasing in the past and will dramatically increase in the future. Lasers in space often fulfill tasks that cannot be accomplished by other means. Examples are measuring distances of millions of kilometers with nanometer precision, detecting trace gases in the atmosphere of Earth from a satellite, or transmitting data between satellites over distances of some 10,000 km at very high rates. With the exception of semiconductor lasers, almost all of the la- sers used in space are optically pumped solid state lasers.

Autonomous Planetary Payload Survival Support System (APPS)

The objective of the APPS study has been to investigate the feasibility, architectural and system design, and potential performance of a non-nuclear system whose single goal is to provide survival and servicing support to a planetary payload element, in order to ensure its operations despite the absence of sunlight for extended periods. The principle aim is to advance concepts and overall approaches to meet this goal, and to provide a framework for the future development of key technologies.

Simplified models for spacecraft vulnerability assessments in early design phase

The space debris environment poses an ever-increasing risk to spacecraft particularly in low Earth orbits (LEO). Due to limitations of existing vulnerability models, increasing the overall survivability of a spacecraft by enhancing the protection of sensitive parts was not possible in the past. The aim of this study was to adopt and develop methodologies that allow increasing the survivability of a spacecraft by varying individual parameters, e.g. the position of sensitive components or the thickness of component casings.

Application of a Bit Torrent-like Protocol and Data Distribution Model to Mission Operations

Current evolution of IP networks has raised the opportunity to consider the use of well-established and mature Internet communication models for use in space missions. One of the most attractive of these models, particularly in terms of distributed and resilient data delivery, is the 'torrent'. A complete implementation of the CCSDS File Delivery Protocol (CFDP) [AD1] has been recently delivered to ESOC.
