Ares-I MLP

The brand-new mobile launch platform being built for the (probably doomed) Ares-I launch vehicle, which the Constellation program will use to send the Orion spacecraft into orbit (assuming Ares doesn't get cancelled).

Note the truss segments to the left - these are parts of the launch umbilical tower which will be built atop the platform. Like Apollo and unilike Shuttle, Ares-I will carry its service tower on the launch platform with it, instead of it being built into the pad.

Behind the truss segments to the left are the tail service masts from a Shuttle MLP.
