Parker Solar Probe Completes Launch Simulation Vibration Testing

To ensure that NASA’s Parker Solar Probe will be able to withstand the physical stresses of launch, engineers at the Johns Hopkins Applied Physics Laboratory – where the probe was designed and is being integrated and tested – used a special device called a shaker table to simulate the forces of being hurled into space. The spacecraft successfully passed vibration testing, or “vibe,” as the engineers call it, in late October.

“Our vibration testing uses our 40,000-pound force shaker to simulate many of the dynamic events that occur during launch and powered flight,” said APL’s Dave Persons, Parker Solar Probe lead structural engineer. “By safely simulating that process here in the clean room, we’re able to fully monitor the spacecraft and make sure it’s cleared for flight. During the test, we actively monitored over 300 channels of data.”
