At 16.00 yesterday I watched a control room of scientists jump for joy. They had just received a signal from the Philae lander telling them it had safely landed on comet 67P/Churyumov-Gerasimenko.
Philae has already started sending back pictures like this one. Pretty soon it will be examining the surface of the comet in different ways. Scientists hope to find out what role comets played in the birth of the Solar System.
I can't wait to see the exciting things Philae will discover.
We have an exhibit on the Rosetta/Philae mission in the Antenna gallery.
