Indeed! Over 20 years of preparation for this mission cumulates in a few hours. If this succeeds it is another huge step for humanity in deep space exploration. We need to get out there and learn more about our Universe!
The lander Philae is on its about 20 km long way down to the comet since around 10:00 o'clock CET. I watched the undocking from Rosseta live on TV. The landing should be around 17:00 o'clock CET, but now it is all on automatic as far as I understood. With the signal transmission delay of about 30 minutes for the 500 million km distance, it will be hard to do last second corrections I suppose. The actual landing should be around 16:30, but we will not know if it worked until 17:00, due to the transmission delay.
I wonder why they do not have a live stream from one of the onboard cameras all the time. That would have been awesome, but I bet the transmission bandwidth is a problem and the technology of Rosetta is more than 15 years old. Measured by todays standards it is probably like steam-driven technology. ;-)
I hope the landing will be successful.
