Early career

In 1989, Madsen joined the

Pathfinder Mission 1997

Madsen participated in the design and analysis of the five Danish magnetic properties experiments flown on the 1997

mission. On the mission, patterns of Martian dust formed on the grey plates with built in magnets revealing the magnetic properties of the dust, thus giving hints of the chemical composition of the magnetic component in the dust and geological formation. Knudsen's team was one of the two non-US teams who were working with

on the Pathfinder Mission, the other team was German. The results from the magnetic properties experiments showed that there had not been liquid water on the surface of mars for the last 2 billion years.


Mars Polar Lander 1999

After the success of the Pathfinder mission, Madsen's team continued developing the next generation of magnetic properties experiments for the 1999
Mars Polar Lander The Mars Polar Lander, also known as the Mars Surveyor '98 Lander, was a 290-kilogram robotic spacecraft lander launched by NASA on January 3, 1999, to study the soil and climate of Planum Australe, a region near the south pole on Mars. It for ...
mission. Two of the three magnetic properties experiments were identical to the ones flown on the Pathfinder mission. Contact with the Mars Polar Lander was lost on 3 December 1999 during landing of the spacecraft.


Mars Exploration Rover Mission 2003

Knudsen, Madsen and their research group designed magnetic properties experiments on board each of the two rovers, Spirit and Opportunity, of the 2003
Mars Exploration Rover NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, ''Spirit (rover), Spirit'' and ''Opportunity (rover), Opportunity'', exploring the planet Mars. It began in 2003 with the launch of the two rover ...

. They were designed to capture magnetic dust liberated from the Martian rocks during abrasion. The dust was analysed by onboard instruments including cameras using various spectroscopy filters. The results from the magnet experiment was considered a success in that they helped the understanding of how the dust on Mars was composed and built up. Members of the team, including Madsen, were at the control center at the

Phoenix 2007

In 2007, Madsen's team was invited by NASA to design the three radiometric calibration targets for the Phoenix mission called "Improved Sweep Magnet Experiment" (ISWEEP). The target consisted of an aluminum holder (carrying structure) containing a palette of different calibrated colors of synthetic pigmented rubber with "sweeping magnets" underneath to clear the colored material of the magnetic Martian dust, assisting in calibrating the cameras of the mission
