26		-On Mars, no satellite systems are available that would enable or facilitate navigation. Alternative methods of electronic navigation are therefore required. A local system, independent on larger-scale infrastructures, is of particular interest. It can be centrally deployed from a landing site and may be scaled up along with the area in which it is meant to operate.The Astronaut Location Interferometry eXperiment (ALIX) aims to perform (live) location tracking of astronauts or mobile platforms using a compact mobile radio transmitter, a set of reference beacons, and a small network of receiver stations. The location tracking shall operate over an area of several square kilometers at meter-scale accuracy. Comparing the ALIX tracking results to positions reconstructed by other systems (e.g. GNSS) will further improve this technology. Ultimately, ALIX will be developed into a reliable system for limited-range location tracking, using minimal number of resources and infrastructure.ALIX uses a mobile transmitter that emits a radio signal. At various stationary receiver stations, the phase of this signal will be measured at regular intervals. With two receiver stations each, the phase difference at the corresponding measurement time can be calculated, hence the position of the transmitter can be tracked. To aid in synchronization of the receiver stations, the use of stationary transmitter beacons is planned. They will transmit at slightly different frequencies than the mobile transmitter, thus providing reference measurements to perform phase corrections.
	16	+Astronauts experience psychological challenges during a planetary mission caused by isolation from other human beings. Moreover, astronauts are dependent on the Life Support System (LSS) to withstand the rough, Martian environmental conditions. A proper, human centered LSS, which is controlled and understood easily by the astronaut is essential for a successful Mars mission.

	18	+Staying Alive deals with the revitalizing component of the LSS in a habitat in form of a photobioreactor (PBR). PBRs have already been researched in the past, however, only a scientific basis. Staying Alive comprises three aspects of the PBR:
28	28
	20	+* Communication and operation
	21	+* The user interface
	22	+* Contribution to the crew’s mental health
	23	+
	24	+The aim of Staying Alive is to investigate the interaction between the astronaut and the PBR. Additionally, a highly interactive sensor system will be tested. The sensor network shall be able to communicate with humans to learn from experience and new data, to explain its decisions and thus become a team member rather than a data source.
	25	+
	26	+For the mission experiment, a small and simplified PBR will be used in the AMADEE-24 habitat. It uses non-toxic photosynthetic organismsto produce oxygen from ambient air and will be equipped with sensor and a user interface for interaction. During the experiment the crew must perform several tasks once fully autonomously and once jointly with the Mission Support Center (MSC). The tasks to be performed include set-up, maintenance, repair, and science activities. Pre-and post-mission questionnaires as wellas video recording will be used to obtain data.
