Word today that the MMRTG has been installed on the rover, so seems like a good time to start the launch thread. Launch currently scheduled for 30 Jul, 2-hr window opening at 1150 GMT.
GO PERSEVERANCE!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I think it is just a generic point near the centre of the ellipse. The real landing will deviate somewhat in both entry point and trajectory through the atmosphere, as well as the direction onboard navigation takes it when firing the thrusters. Definitely smart enough not to land on a giant slope!
P.S. my own question for anyone in the know: any plans on MRO attempting imaging like MSL, or does the bent-pipe relay attitude preclude it this time around? I could really use a new avatar.... |

PlanetFest 21 happened this weekend (run by the Planetary Society) and there was an amazing talk by Rob Manning of the details of the landing. The ellipse (which this time is really a circle) they could come down in is about the size of Manhattan but the expectations are that the lander would emerge in powered descent somewhere near the center of it which is somewhat near the delta but below it in the crater. The onboard navigation system is designed to locate the closest safe spot to where it figures out it is and aim for that. He said that they determined there were safe spots to be found at all parts of the ellipse within close proximity. Eventually that talk will be posted to the Planetary Society's Youtube page so watch for it. The engineering he described is amazing. He also said that MRO will be tasked with not only going after a shot of the lander on the parachute but also during the actual powered landing as well if they can get lucky. |
