A summary of all former and currently planned FMI Space Projects is shown here.

Rosetta/Philae's primary mission ended this morning, 15.11.2014, 03:15 Finnish time

After the depletion of the primary battery and the recharged secondary battery the contact between Rosetta and Philae stopped and re-started a few times until it failed completely. Last information showed the empty battery status. Philae's control system as final activity changed into Long Term Science mode and activated its low-power stand by mode where it will remain until sufficient solar power is available for a restart.

Seperation and Landing:

Separation happened as planned on 12.11. at 10:35 Finnish time. After 2 hours of flight without communication the radio link between Philae and Rosetta was established 13:00. All operations during the descent were performed as planned, all systems were nominally,

After precise point landing in the intended area neither down-hold thruster nor the harpoons activated successfully. The ice screws were not able to hold the lander which took off again for another 2 hours flight after which it settled in a niche of a cliff at the edge of area 'B'. Here it performed most of the intended initial measurements before shutting down when the batteries run out.

Problems: APXS doors did not open, so that only reference spectra were measured, the MUPUS-PEN was not able to penetrate into the very hard ice body and stands now only inside the dusty top layer. The measurement sequence itself went as planned. It is not clear how deep the drill entered the soil and if the taken sample contained much material for the subsequent analysis by COSAC.

Due to the shadowing on three sides the efficiency of the solar panels for accu recharging during only 1.6 hours sun light is not high. It was improved by a final rotation of the Lander body presenting the largest available panel towards the opening

Advantages: The "hopping" from the original to the final landing site allowed measurement of species from different locations which showed to be significantly different. The danger of getting fast a cover of the solar panels is much smaller than at the original landing site. Due to its protection it might be able to operate even close to the Sun and beyond perihelium without the danger of overheating which otherwise would have terminated the Philae mission latest in March 2015.

The ExoMars DREAMS Instrument Package is Integrated

On November 6 the Engineering Model of the Meteorological instrument package DREAMS (Dust Characterization, Risk Assessment, and Environment Analyser on the Martian Surface) on board ESA's Exomars 2016 Entry, Descent and Landing Demonstrator Module (EDM) Schiaparelli was successfully integrated. As it has the same form factor and functionality as the final flight model it was the most important step towards the final flight model. FMI' Radar and Space Research is delivering the flight model of the pressure and Humidity sensors in the next days for integration in Italy.


FMI participates in NASA's Mars 2020 Lander Program

On July 31 NASA publishes the instrument consortium participating in the Mars 2020 rover. FMI's pressure and humidity sensor are part of the Spanish-led MEDA (Mars Environmental Dynamics Analyzer) instrument package.

Mission timeline: Launch July/August 2020, arrival Jan/March 2021, landing as the Curiosity rover with a sky crane. Nominal mission duration 669 days (1 Martian year) with direct communication capability Rover - Earth.
