Waking up with a little help from our friends – Part 2

Not only is NASA helping Rosetta exit hibernation: ESA’s very own Mars Express has been standing in for Rosetta in a series of crucial tests to ensure the NASA ground stations are ready to track the comet chaser. Andy Johnstone, from the Mars Express team here at ESOC, sent in this report. Although all the attention for Rosetta wake up is mainly on the spacecraft itself, the other half of the equation is the ground stations that will be used to listen for the signal, NASA’s DSS-14 in Canberra and DSS-63 in Goldstone. If, by chance, no signal were to be detected on 20 January, this could mean that either (a) Rosetta...

Rosetta and Philae engineering testing at ESOC today

The joint ESA/DLR team are working this week at ESOC, testing the Philae lander simulator together with the Rosetta engineering model (photos in Flickr). ESA’s Armelle Hubault, from the Rosetta flight control team, just sent in this update: Today, we are simulating the need for a shift in the separation time, i.e. the time when the lander separates from the Rosetta spacecraft. The purpose of this test is to verify that the procedures we have in place to shift all Lander activities is working as expected. In our simulation, separation was originally planned at 15:00 CET, (and all the Lander data commands were uplinked as they would be, using this time). Then,...
