In order for off-Earth top surface structures built from regolith to protect astronauts from radiation, they need to be several meters thick. Technical University Delft (TUD) proposes to excavate into the ground to create subsurface habitats. By excavating not only natural protection from radiation can be achieved but also thermal insulation because the temperature is more stable underground. At the same time through excavation valuable resources can be mined for through in situ resource utilization (ISRU). The idea is that a swarm of autonomous mobile robots excavate the ground in a sloped downwards spiral movement. The excavated regolith will be mixed with cement, which can be reproduced on Mars through ISRU, in order to create concrete. The concrete is 3D printed/sprayed on the excavated tunnel to reinforce it. As soon as the tunnels are reinforced, the material in-between the tunnels can be removed in order to create a larger cavity that can be used for inhabitation. Proposed approach relies on Design-to-Robotic-Production (D2RP) technology developed at TUD1 for on-Earth applications. The rhizomatic 3D printed structure is a structurally optimized porous shell structure with increased insulation properties. In order to regulate the indoor pressurised environment an inflatable structure is placed in the 3D printed cavity. This inflatable structure is made of materials, which can also be at some point reproduced on Mars through ISRU. Depending on location the habitat and the production system are powered by a system combining solar and kite power. The ultimate goal is to develop an autarkic D2RP system for building subsurface autarkic habitats on Mars from locally obtained materials.

The possibility of using optical communications in free-space as an improvement of current RF communication systems was analyzed in this Project. The particular case of a link Mars-Earth was studied and a link based in the future NASAs MLCD project,
which is currently being developed, was designed. For this, an orbit simulator was programmed, evaluating the transfer orbit, analyzing the losses that occur in the transmission channel, using several atmospheric models, selecting the most adequate elements for the transmitter and the receiver, calculating the Doppler effect during the mission, and performing a budget link for the different orbit positions. From these results, the maximum bitrate through the MLCD mission was evaluated for the different astronomical observatories chosen as optical ground stations.
Wind is the process that connects Mars climate system. Measurements of Mars atmospheric winds from orbit would dramatically advance our understanding of Mars and help prepare for human exploration of the Red Planet. Multiple instrument candidates are
in development and will be ready for flight in the next decade. We urge the Decadal Survey to make these measurements a priority for 2023-2032.
This 2020 Decadal Survey White Paper reviews what is known about lunar and martian lander Plume Surface Interactions (PSI) during powered descent. This includes an overview of the phenomenology and a description of the induced hardware and environmen
tal impacts. Then it provides an overview of mitigation techniques and a summary of the outstanding questions and strategic knowledge gaps. It finishes with five recommendations: to include dedicated descent imagers on every surface mission so that PSI can be directly recorded and reviewed by ground teams; as far as possible, to make all data related to PSI effects publicly accessible; to develop methods and instruments for making key measurements of PSI; to assess and record key flight data; and to invest funding into studies of long-term infrastructure architectures and mitigation techniques.
We present here SPECULOOS, a new exoplanet transit search based on a network of 1m-class robotic telescopes targeting the $sim$1200 ultracool (spectral type M7 and later) dwarfs bright enough in the infrared ($K$-mag $leq 12.5$) to possibly enable th
e atmospheric characterization of temperate terrestrial planets with next-generation facilities like the $textit{James Webb Space Telescope}$. The ultimate goals of the project are to reveal the frequency of temperate terrestrial planets around the lowest-mass stars and brown dwarfs, to probe the diversity of their bulk compositions, atmospheres and surface conditions, and to assess their potential habitability.
The Los Alamos National Laboratory designed and built Mars Odyssey Neutron Spectrometer (MONS) has been in excellent health operating from February 2002 to the present. MONS measures the neutron leakage albedo from galactic cosmic ray bombardment of
Mars. These signals can indicate the presence of near-surface water deposits on Mars, and can also be used to study properties of the seasonal polar CO$_2$ ice caps. This work outlines a new analysis of the MONS data that results in new and extended time-series maps of MONS thermal and epithermal neutron data. The new data are compared to previous publications on the MONS instrument. We then present preliminary results studying the inter-annual variability in the polar regions of Mars based on 8 Mars-Years of MONS data from the new dataset.
