Cool!

That means our cloaking technology was successful against those pesky aliens that have blasted last few probes.

Onward to planetary colonization!

Re:Why can't we just sned a KH11?

[Wyatt Earp]

Because a KH-11 is heavy.

14 tons for a KH-11, 18 tons for the Improved Crystal.

Niether the Americas, ESA or Proton have rockets with the throw-weight to chuck 18 tons of KH-11 to Mars.

The Atlas III can launch 4,500 kg. to a Geosynchronous transfer trajectory

The Delta IV Large can launch 10,843 kg. to a Geosynchronous transfer

The Ariane 5 can launch 6,800 kg. to a Geosynchronous transfer

Shuttle might do it - 24,000 kgs to LEO, but you'd have to have a big boster. Perhaps if Saturn hadn't been killed, or Energia. But right now no one has the rocket to send something like that to Mars.

Touching scene in mission control

I was watching the mission control footage, when the satellite came out of Mars' shadow, two mission control geeks went to high five each other, and missed. That's NASA for you: nerding it old school. ;-)
