Messages in The Pod Bay and Space.com's NASA: Mars rover Perseverance in 'safe mode' after launch, but should recover both said that Perseverance was in "Safe Mode".

Is it still?

  • $\begingroup$ There was also an issue with the spacecraft being so close to Earth, that the signal was too strong for the DSN. Apparently Perseverance is a close talker. $\endgroup$ – DrSheldon Jul 31 '20 at 17:26
  • $\begingroup$ @DrSheldon that's interesting; I can understand that in the very early part some antennas might not have enough range of attenuation, but all one has to do is point the dish a little to one side to get any desired amount of attenuation. That might make conical scanning impossible or at least difficult, but with such a strong signal one could just use automated, computed pointing rather than active tracking. But I can't post a new question about it until you can confirm that you're pretty sure this was a real issue. Thanks! $\endgroup$ – uhoh Jul 31 '20 at 17:45

    $\begingroup$ The too-stong-signal is mentioned in the space.com article that you cite in this question. $\endgroup$ – DrSheldon Jul 31 '20 at 18:07
  • $\begingroup$ @DrSheldon oh! okay I'll look tomorrow (it's 2 AM) $\endgroup$ – uhoh Jul 31 '20 at 18:18

Is Perseverance still in Safe Mode?

Not any more: NASA's Mars rover Perseverance is fine and out of 'safe mode' as of July 31, 2020.


It was as of the latest update, but they were working on recovering it. They have full communication with the spacecraft as of now. The press release, issued on July 30, stated the following:

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.

These things usually take a day or so. Bottom line is, there isn't a lot to worry about for now.

  • $\begingroup$ okay that's a relief, I was worried about it being another spacecraft mutiny! ;-) $\endgroup$ – uhoh Jul 31 '20 at 2:09
