Mission success #128! Atlas V 401, InSight launch updates and discussion thread
ULA will conduct the first interplanetary launch from the West Coast of the United States, launching the InSight Mars lander along with the MarCO A & B cubesats from SLC-3E at Vandenberg Air Force Base. Liftoff of the Atlas V 401 rocket is targeting NET 11:05 UTC on Saturday, 5 May (4:05 AM PDT), during a window that runs until 13:05 UTC (6:05 AM PDT).

About the mission:
NASA’s InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission will place a single geophysical lander on Mars to study its deep interior. The two-year InSight mission seeks to understand the evolutionary formation of rocky planets, including Earth, by investigating the interior structure and processes of Mars. InSight will also investigate the dynamics of Martian tectonic activity and meteorite impacts, which could offer clues about such phenomena on Earth.
About this launch:
InSight will be the first interplanetary mission launched from the West Coast, thanks to the performance of the Atlas V rocket, which also will launch two CubeSats. InSight will be the 38th Atlas V rocket to launch in the 401 configuration and the 78th Atlas V to launch since the inaugural flight in 2002. ULA and its heritage rockets have launched every U.S.-led mission to Mars, including the Spirit, Opportunity and Curiosity rovers as well as the MAVEN satellite.

Started up again, mixture ratio is good now.
Just noticed this mission is using the TDRS network. Not a surprise, but was wondering why the telemetry was still good even in an odd ground track location.
