Title: Perseverance Mars Rover
Post by: BridgeTroll on June 21, 2020, 08:30:43 AM
I have followed and posted about the Mars rover program for years and am super excited about the launch of Perseverance in July.  Below is a link to a really good primer of the launch, entry, descent and landing, landing site, instrumentation.

Jezero crater appears to be a ancient flood plain with clear and obvious former water channels. One of the most exciting instruments is a helicopter with flights up to 15 feet high, 60 feet in distance and 90 seconds in duration.

Please take a few minutes and click the link below to learn more...  8)

I watched the helicopter deployment video, and have a question.
It shows the protective panel dropping, then the 'copter being flipped over and dropped to the surface. Does that rotation move the helicopter out from under the lander? Otherwise, it would drop on that cowling, and taking off would be harder.

Good question. I don’t know but the copter is supposed to fly multiple times so my guess is it reloads onto the rover

It flies multiple times but does not come back to the rover.   Great article describing the research and testing of the helicopter...

I am guessing a second mission helps with getting the samples back to earth? Am I reading the sample collection goals correct? Very exciting mission.

NASA’s Perseverance rover is set for launch Thursday from Cape Canaveral during a two-hour window opening at 7:50 a.m. EDT (1150 GMT). A United Launch Alliance Atlas 5 rocket will fire spacecraft away from Earth with a relative velocity of 24,785 mph, or about 11 kilometers per second.

That’s enough speed to break free of Earth’s gravitational grip and speed toward Mars, aiming for the point in space where the Red Planet will be Feb. 18, 2021, the Mars 2020 mission’s designated landing date.

War of the Worlds  reversed... If you were a Martian looking towards earth today you might see three separate rockets headed for your planet...  :D

The USA joined China and UAE with a probe to Mars today... all should arrive around February...
