“…Indeed, one of the main challenges of the first landing on a comet was the fact that very little was known about the target prior to Rosetta's arrival, which was only in August 2014, about 3 months before landing [10]. 67P/ChuryumovGerasimenko turned out to have an unexpected shape and rough surface [11], which limited the possible areas for landing.…”

“…Setting the first human in orbit around Earth was only the beginning (1); a few years later a number of manned and unmanned missions had managed to establish human presence on the moon (2), land robotic missions on planet Mars (3,4) and, very recently, visit an actual comet (67P/Churyumov-Gerasimenko) (5). Although a reduction in manned space missions has been the status quo for the past few decades, it now seems that a new age of space exploration is at the doorstep and major space agencies have announced their plans towards realising this new age by gradually re-advancing from Low Earth Orbit (LEO) missions to the Moon and later onto the planet Mars (6,7).…”

Powder Bed Fusion (PBF) is a range of advanced manufacturing technologies that can fabricate three-dimensional assets directly from CAD data, on a successive layer-by-layer strategy by using thermal energy, typically from a laser source, to irradiate and fuse particles within a powder bed.The aim of this paper was to investigate the application of this advanced manufacturing technique to process ceramic multicomponent materials into 3D layered structures. The materials used matched those found on the Lunar and Martian surfaces. The indigenous extra-terrestrial Lunar and Martian materials could potentially be used for manufacturing physical assets onsite (i.e. off-world) on future planetary exploration missions and could cover a range of potential applications including: infrastructure, radiation shielding, thermal storage, etc.Two different simulants of the mineralogical and basic properties of Lunar and Martian indigenous materials were used for the purpose of this study and processed with commercially available laser additive manufacturing equipment. The results of the laser processing were investigated and quantified through mechanical hardness testing, optical

“…The Rosetta spacecraft reached its target, 67P/Churyumov-Gerasimenko in August 2014 after ten years of cruise (Accomazzo et al 2015). Observations with the ten orbiter instruments allowed a first characterization of nucleus and activity and thus the selection of a landing site for Philae , which successfully landed on November 12th, 2014 .…”

On December 3rd, 2014, the Japanese Space Agency (JAXA) launched successfully the Hayabusa2 (HY2) spacecraft to its journey to Near Earth asteroid (162173) Ryugu. Aboard this spacecraft is a compact landing package, MASCOT (Mobile Asteroid surface SCOuT), which was developed by the German Aerospace Centre (DLR) in collaboration with the Centre National d'Etudes Spatiales (CNES). Similar to the famous predecessor mission Hayabusa, Hayabusa2, will also study an asteroid and return samples to Earth. This time, however, the target is a C-type asteroid which is considered to be more primitive than (25143) Itokawa and provide insight into an even earlier stage of our Solar System.Upon arrival at asteroid Ryugu in 2018, MASCOT will be released from the HY2 spacecraft and gently descend by free fall from an altitude of about 100 m to the surface of the asteroid. After a few bounces, the lander will come to rest at the surface and perform its scientific investigations of the surface structure and mineralogical composition, the thermal behaviour and the magnetic properties by operating its four scientific instruments. Those include an IR imaging spectrometer (MicrOmega, IAS Paris), a camera (MASCAM, DLR Berlin), a radiometer (MARA, DLR Berlin) and a magnetometer (MASMAG, TU Braunschweig).In order to allow optimized payload operations the thermal design of MASCOT is required to cope with the contrasting requirements of the 4-year cruise in cold environment versus the hot conditions on the surface of the asteroid. Operations up to 2 asteroid days (∼16 hours) based on a primary battery are currently envisaged. A mobility mechanism allows locomotion on the surface. The mechanism is supported by an attitude and motion sensing system and an intelligent autonomy manager, which is implemented in the onboard software that enables MASCOT to operate fully independently when ground intervention is not available.
