PVT-GAMERS experiment to fly in FYT! 2018 campaign

The improved Pressure-Volume-Temperature Gauging Method for Electric Propulsion Systems (PVT-GAMERS) has been one of the two selected projects to be included in the ESA’s Fly Your Thesis! 2018 campaign, which will take place in Autumn 2018. The PVT-GAMERS is a technological demonstrator proposal, aimed at validating a new methodology by operating it in a representative environment, in this case a zero-g and a modified-g scenario. In the future, this method may be used in propellant tanks of any electric propulsion spacecraft to determine, in the absence of gravity, the amount of remaining propellant during the full duration of its mission.

Still more about Martian water

A recent study published in Scientific Reports, an open access Nature magazine’s journal, points to the likely possibility that Slope Streaks, one of the most conspicuous topographic features of the surface of Mars, have deliquescence as their root cause. The paper,entitled Martian slope streaks as plausible indicators of transient water activity and led by the Atmospheric Science Group with Anshuman Bhardwaj as first author, enhances the importance of the ground-atmosphere water exchange cycle and its liquid state phases in the Martian environmental dynamics, a matter that will be directly investigated by means of the HABIT instrument for the first time during the ExoMars 2020 mission. [...]

Successful 1st trial of PACKMAN-B

A first trial of a balloon version of the Particle Counter K-index Magnetic Anomaly (PACKMAN-B) took place last 30th August in Córdoba, Spain, on board a balloon launched from the city airport. Everything went as expected, and PACKMAN-B provided a first set of data which, even though won’t be valuable from a scientific point of view because of the latitude, have demonstrated the readiness and robustness of the instrument. The flight was scheduled by Zero2Infinity, a Spanish company devoted to the rendering of balloons and reusable rockets flights for the space industry and for scientific purposes. [...]

The thorough selection of ExoMars 2020 landing site.

To land a spacecraft on Mars is not an easy goal. Apart from the technological challenges it entails, there is another question which could seem prosaic but which require a painstaking and intense process of elucidation: the selection of the landing site. Professor Javier Martín-Torres and Professor María Paz Zorzano Mier, Principal Investigator and Co-Principal Investigator of the ExoMars 2020’s instrument HABIT [...]

Interview with Christer Fuglesang
Christer Fuglesang visited Luleå University of Technology’s Rymdcampus in Kiruna, where he gave a talk about his remarkable career as an astronaut and reviewed the main problems posed within human space exploration regarding his field of expertise: radiation. As the current director of the Royal Institute of Technology’s (KTH) Space Center, he presented a list of the ongoing projects of the institution with respect to this same topic and others. [...]

Field Site campaigns

HAbitability, Brines, Irradiation and Temperature (HABIT) is a novel instrument never used before in the exploration of Mars, nor even on any other place. Therefore, it is having to be developed from scratch, at least with regard to its Brine Observation Transition To Liquid Experiment (BOTTLE) unit. The Field Site Prototype (FSP-HABIT) has been the first embryo of the device, and has made possible to identify the very basic problems its design and functioning pose, as well as serving as the Master Thesis subject for Johannes Güttler, the master student who built it and tested it, pointing the ways to follow in the subsequent development of HABIT. [...]

The flight of SALACIA

SALACIA (Saline Liquids and Conductivity in the Atmosphere) was finally launched on board the 21 REXUS rocket from Esrange after one day delay with respect to schedule due to the weather conditions. Everything went according to plan and, after the recovery of the rocket, it could be verified that all the systems in the instrument functioned properly and the sensors took the expected measurements. This success gives place to the last but not least stage of the project: the scientific exploitation of the obtained data; the definitive task whose results will give a sense to all the earlier work. [...]

ExoMars and The Atmospheric Science Group

The first phase of the ExoMars programme, the ExoMars 2016 mission, left the Earth last 14 March and, after completing the manoeuvres to get into the correct trajectory, it got its way to Mars, where it arrived last October the 19th. The Atmospheric Science Group of the Luleå University of Technology will be very attentive to the course of the mission, since it is involved in several senses in this mission that will push the limits of the knowledge about Mars environment, and which is going to undertake expressly the direct search for signs of life on the planet. [...]

Improved PVT Gauging Method

Members of the Atmospheric Science Group have developed a new method to gauge the propellant content in the tanks of modern spacecrafts equipped with electric propulsion (EP) thrusters. It is called Improved Pressure-Volume-Temperature (PVT) method, and it allows for retrieving the amount of propellant throughout the whole operational lifetime of the spacecrafts with an accuracy 8 times higher than with the usually applied methods, which show increasing inaccuracy towards the end of the nominal missions, when the amount of propellant in the tank is scarce. The work, supported by experimental confirmation in laboratory, has been published in the International Journal of Mechanical, Aerospace, Industrial, Mechatronic and Manufacturing Engineering (A Xenon Mass Gauging through Heat Transfer Modeling for Electric Propulsion Thrusters). [...]

The study of Martian Water Quandary

The recently published paper Should we invest in Martian brine research to reduce Mars exploration costs? (Astrobiology, available online), authored by Professor Javier Martín-Torres and Professor María Paz Zorzano, focuses on one transcendent problem posed by the discovery of the formation of transient liquid brines on the surface of Mars: the presence of liquid water will mark the most interesting points to be explored by the coming missions, which are at the same time the points where an extreme caution must be observed in order to avoid an eventual and catastrophic contamination of the Martian environment with terrestrial organisms.
