NASA’s MAVEN spacecraft, a Mars orbiter that’s now virtually a decade outdated, is again up and operating following a scare that noticed it put into secure mode for a number of months. The Mars Environment and Risky EvolutioN craft resumed science operation on Might 28, 2022, NASA recently announced, after recovering from the difficulty.
The issue started in February 2022, when a problem with the spacecraft’s navigation system meant it may not decide its orientation. The crew misplaced contact with the spacecraft on February 22, whereas it was performing routine operations on its Inertial Measurement Models (IMUs). There are two IMUs on board the spacecraft, one main and one backup. These units use gyroscopes and accelerometers to measure the actions of the spacecraft as a part of the navigation system. Each IMUs stopped working, so whereas the spacecraft may boot up and function its different devices, it couldn’t decide its place in house.
After a reboot and switching to its backup laptop, MAVEN did handle to get information from the second IMU. However this IMU was close to the top of its lifespan, so the spacecraft needed to be put into secure mode, a minimal working mode, to stop injury to the IMU or another methods.
Because the backup IMU would solely final for therefore lengthy, the crew hurried to complete a navigation various they’d been engaged on. This technique used the celebrities to find out the spacecraft’s place with out the necessity for an IMU. In what NASA describes as a “race in opposition to time,” the crew at Lockheed Martin, the spacecraft producer, needed to develop this new mode 5 months forward of schedule to get it deployed to MAVEN so the spacecraft may maintain working.
When the crew uploaded the brand new software program to MAVEN in April they powered off the backup IMU, to reserve it in case it’s wanted once more sooner or later. They examined the brand new system and powered the orbiter’s devices again up, and as soon as every part was confirmed to be working, the spacecraft resumed full operations.
In addition to gathering information on the Mars environment, MAVEN additionally acts as a communication relay, relaying information between Mars explorers on the floor just like the Perseverance rover and Earth. With the resumption of its actions in each capacities, NASA states that it ought to have the ability to maintain working into the long run, though the crew might want to discover new methods to manage the spacecraft within the few occasions per 12 months that the IMUs are wanted.
“This was a important problem dealing with the mission, however due to the work of our spacecraft and operations crew, MAVEN will proceed producing vital science and working as a relay for the floor belongings by means of the top of the last decade,” mentioned Shannon Curry, MAVEN’s principal investigator on the College of California, Berkeley, in a press release. “I couldn’t be prouder of our crew.”
