When a vessel enters safe mode, it shuts down all but essential systems until it receives new commands from mission control. "Right now, the Mars 2020 mission is completing a full health assessment on the spacecraft and is working to return the spacecraft to a nominal configuration for its journey to Mars," added NASA.
The spacecraft also experienced a delay in setting up its communications link with the Jet Propulsion Laboratory in Pasadena, California, its mission control.
Mars 2020 sent its first signal to ground controllers at 9:15 am (6:45 pm IST) but it was not until 11:30 am (9:00 pm IST) that it established telemetry -- more detailed spacecraft data.
Matt Wallace, the mission's deputy project manager, said that the fact that the spaceship had entered safe mode was not overly concerning.
"That's perfectly fine, the spacecraft is happy there," he said.
"The team is working through that telemetry, they're going to look through the rest of the spacecraft health.
"So far, everything I've seen looks good, so we'll know more in a little bit."
