JFK-1 Posted Monday at 03:29 Share Posted Monday at 03:29 I have been wondering how they tested the drone to fly in the extremely thin Martian atmosphere. Vacuum chamber maybe. And we still don't yet know if it will indeed fly. Quote Relative to Earth, the air on Mars is extremely thin. Standard sea-level air pressure on Earth is 1,013 millibars. On Mars the surface pressure varies through the year, but it averages 6 to 7 millibars. That's less than one percent of sea level pressure here. To experience that pressure on Earth, you would need to go to an altitude of about 45 kilometers (28 miles). Quote Link to post Share on other sites

Yes they used a chamber to simulate the thickness of the air on Mars and used lines attached to the drone to simulate the weaker gravity. LOTS of pictures expected to be released at some point today, including the video of the sky crane descent Quote Link to post Share on other sites

To be fair the parachute worked to slow down, and I have had a drone up Ben Glass and Ben Lawyers, Parachute was made in Scotland Quote Link to post Share on other sites

Jamhammer Posted 20 hours ago Share Posted 20 hours ago There’s a panoramic pic of the night sky on Mars taken from the rover. It was on fb but can’t find it anywhere now. Incredible Quote Link to post Share on other sites
Horatio Caine Posted 19 hours ago Share Posted 19 hours ago Looked like quite a nice day on Mars. wee bit of a breeze which would increase the wind chill I suppose... Quote Link to post Share on other sites

The guy that made that 360 VR picture has now been forced to add a disclaimer in the description of his picture, admitting to the edit. The one I posted above is the original raw photo.
