Work continues on the +NASA TESS cameras at +Massachusetts Institute of Technology (MIT) All four of the TESS cameras that will find new #exoplanets are in testing in environments that simulate the vacuum and temperatures of space.

The event was the Launch Vehicle fit check. It verified the compatibility of the mechanical and electrical interfaces between the +SpaceX Falcon 9 Launch Vehicle and the +Orbital ATK Transiting Exoplanet Survey Satellite - +NASA TESS Spacecraft.

The mission is about to enter the Observatory Integration and Test phase. The TESS System Integration Review will occur on May 31 that verifies the readiness for integration of the Instrument and Spacecraft to form a complete Observatory. Orbital ATK will proceed to integrate the Instrument provided by +Massachusetts Institute of Technology (MIT) , comprising four cameras and one instrument data handling unit, and continue into an environmental test campaign.

The two pictures show the TESS spacecraft mounted to the Launch Vehicle payload adapter. In one photograph, there is the small team that performed the test activities. In the other photograph, there is a larger group of TESS personnel. Each photograph has persons from the +NASA Goddard Space Flight Center TESS project, the Orbital ATK Spacecraft program, the SpaceX Launch Vehicle team, and the +NASA's Kennedy Space Center's Launch Services Program.

The last +NASA TESS flight detector, a spare, was installed in a small thermal vacuum chamber at +Massachusetts Institute of Technology (MIT) for testing. The team uses a range of different sized chambers to test hardware.

The +NASA TESS lens hoods are ready to meet their cameras which will find new #exoplanets! The lens hoods help block stray light to help create the best images from the cameras.
