Endeavour landed this morning at 02:35, thereby ending it's service to Space Exploration. With Atlantis due either this or next month, on her return, the STS era will be over.

A brilliant tribute to Endeavour.

Got to wonder what will replace them.

Ares (rocket) & Orion (Orbiter), but I personally don't think that they will capture people's imaginations as much as the Mercury, Gemini, Apollo & STS missions.
