During the environmental testing phase, the orbiter will undergo a variety of rigorous tests that simulate the extreme temperatures, vacuum and vibration the spacecraft will experience during the course of its mission. Currently, the spacecraft is in the company's Reverberant Acoustic Laboratory being prepared to undergo acoustics testing that simulates the maximum sound and vibration levels the spacecraft will experience during launch.
Following the acoustics test, MAVEN will be subjected to a barrage of additional tests, including: separation/deployment shock, sine vibration, electromagnetic interference/electromagnetic compatibility (EMI/EMC), and magnetics testing. The phase concludes with a thermal vacuum test where the spacecraft and its instruments are exposed to the vacuum and extreme hot and cold temperatures it will face in space.
"The assembly and integration of MAVEN has gone very smoothly and we're excited to test our work over the next six months," said
Guy Beutelschies, MAVEN program manager at Lockheed Martin Space Systems Company. "Environmental testing is a crucial set of activities designed to ensure the spacecraft can operate in the extreme conditions of space."
"I'm very pleased with how our team has designed and built the spacecraft and science instruments that will make our measurements," said
Bruce Jakosky, MAVEN principal investigator from the
University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics. "We've got an exciting science mission planned, and the environmental testing now is what will ensure that we are ready for launch and for the mission."
MAVEN is scheduled to ship from Lockheed Martin's facility to NASA's Kennedy Space Center in early August where it will undergo final preparations for launch.
