Postdoc research: Asteroids – mitigating the threat of impacts on the Earth

From 2012 - 2018 I worked at the German Aerospace Center’s (DLR) Institute of Planetary Research in Berlin as a scientific researcher and project manager in the European-Union-funded (FP7) NEOShield project “A Global Approach to Near-Earth Object Impact Threat Mitigation”, followed by the EU Horizon 2020 NEOShield-2 project “Access technologies and characterization for Near Earth Objects (NEOs)” 2015-2017(www.neoshield.net). My research field was the physical properties of NEOs from the point of view of mitigation of impact threats and NEO deflection space missions (see publications list below). Amongst other results, this research has led to a new method of detecting metal-rich asteroids, a means of remotely probing the depth of regolith on asteroids, in addition to a concept for a low-cost asteroid impact test mission called NEOTωIST (NEO Transfer of angular momentum Spin Test).  

For years I was a member of the German delegation to the United Nations’ Action Team 14 on NEO impact hazards and  I represented Germany in the UN-mandated Space Mission Planning Advisory Group (SMPAG) and the International Asteroid Warning Network (IAWN). (www.cosmos.esa.int/web/smpag/ and www.iawn.net) and I was the coordinator of the SMPAG Ad-Hoc Working Group on Legal Issues.

Leadership experience:

My responsibilities in the NEOShield project included project coordination with Alan Harris and interfacing between the project consortium and the funding agency, namely the European Commission. In NEOShield-2 my responsibilities include scientific research coordination and maintenance of the project’s internal website.

After my preliminary work showed the NEOTωIST concept to be viable, I invited a team of NEOShield members to join the effort to prove the concept and design a mission. I coordinate this effort, which has been funded as part of the NEOShield and NEOShield-2 projects.  

In the course of the work of the SMPAG significant questions regarding legal issues in connection with NEO mitigation have arisen. In 2016 I was asked to establish a working group on legal issues under the auspices of SMPAG, which includes 10-15 legal experts in space law or international law and several scientists/engineers as technical experts. I coordinate the work of the group and the report on our findings (expected end of 2018).

For the Planetary Defense Conferences (Flagstaff 2013, Rome 2015, Tokyo 2017) I have been a member of the organizing committees and chair for the session on asteroid physical properties.

For the Didymos Observer Workshop 2018, Prague, I am a member of the scientific organizing committee.

Supervision experience:

Supervision of the master thesis ”Instrumentation for an asteroid kinetic-impactor demonstration mission” by Steffen Weisenberger from University of Würzburg at DLR. May 2016 – October 2016.

Supervision of the experimental project report ”Reflection spectra of a Mars dust analog in the context of NASA's Phoenix Mars Lander” by master student Niels-Kristian Kjøller from University of Copenhagen. June 2010 – July 2010.

Supervision of the bachelor thesis “Reflection spectra of Martian analog dust for calibrating the Phoenix missions iSweep experiment” by Nynne Louise Berthou Lauritsen and Lea Kamille Drescher Sørensen from Copenhagen University. January 2009 – June 2009.

Communication experience

During my university studies I had a job at the well-known Planetarium in Denmark, where I supervised space-related educational projects for school classes, led guided tours, and spoke to large audiences. Altogether I have made presentations to about 200 different groups of people, so my lecturing skills have benefitted from a great deal of experience.

Through first the Martian Phoenix space mission work and later the NEOShield and NEOShield-2 work, I have participated in many interviews for press articles, television, radio, podcasts, and even Twitter. My publications list includes several popular science articles.

Master research: Testing experiment for Phoenix Mars Mission

My master thesis project title was ”Simulation of dust sedimentation on calibration targets for the Surface Stereo Imager onboard Phoenix Mars lander 2007”. I tested the Magnetic Properties Experiment (referred to as iSweep) for the Phoenix mission before the launch in the laboratory using Mars analog material. The work was carried out in the Mars Group at The University of Copenhagen with Morten Bo Madsen as my advisor.

PhD research: Phoenix Mars Mission operation and dust experiment.

I continued working in the same research group to obtain my Ph.D. The work was, however, somewhat different, as the Phoenix launched around the time I started. I spent 4 months at the Phoenix Science Operation Center in Tucson as a member of the science operational team. I was a Downlink Engineer for the Robotic Arm Camera and part of the Atmospheric Science Team, as well as working on my own experiments using available instruments on the mission. After the mission came to an end, I carried out data analysis and further laboratory experiments.

The title of the thesis was “Martian Airborne Dust – Magnetic Properties Experiment on Phoenix and Dust on the MSL Calibration Target”. It can be accessed here:

International Space University and Mars Desert Research Station

During my PhD period I was accepted by The International Space University to participate in a 9 week Space Science Program in the summer of 2009, which was held at NASA Ames. During that time I gained insight into a wide range of space related topics. My professional network expanded greatly as I acquired contacts in many space agencies and companies around the world.

After my time at Ames I was invited by Carol Stoker from NASA Ames Research Center to participate in a 2-week mission at the Mars Desert Research Station in Utah in a team of 6 people who had to work and live under the same conditions as in a mission on Mars (Crew No. 92).

Juno Jupiter mission instrument design

For some months between my Master degree and the start of my Ph.D. studies, I carried out a project at the Danish Technical University (DTU SPACE) with John Leif Jørgensen, where I worked on optimizing the shape of a solar protection cone of the navigation camera for the Jupiter mission JUNO. My work involved investigations of orbital mechanics and transformations between different coordinate systems, to minimize the size of the cone while still protecting the CCD from the sun at all times throughout the mission.

Exchange year at University of California Los Angeles

In 2004 I was accepted as an exchange student by the University of California Los Angeles (UCLA) in the Department of Earth and Space Science, and partly in the Aerospace Engineering Department. In addition to courses, I carried out an independent project with Professor David Paige, in which I filtered different Mars satellite data sets in the search for possible landing sites for the Phoenix mission.

X-ray detector testing for student cubesat

In the last year of my bachelor studies I carried out a bachelor project at the Danish National Space Institute, where I worked on testing the CCD for a student cubesat and calculating the predicted background noise. The title of the project was: ”Characterization of the x-ray detector for the student satellite AAUSAT II”.
