Starting a new topic here - hopefully that's OK! Clearly there will be a lot of action around this in the next weeks and months with descent images and HiRISE views of the hardware.
I thought I had posted this map earlier but apparently not. This shows the various landing ellipses in this area. The original plan was for an ellipse oriented NW-SE, but it changed with the different launch date and is now nearly E-W. Note that the ellipse shown in the recent ESA release is the envelope of all ellipses over a given launch period, but the actual landing ellipse for the given launch date is smaller. Opportunity's final landing ellipse is shown for comparison. http://exploration.esa.int/mars/57445-exom...6-landing-site/ http://exploration.esa.int/mars/57446-exom...6-landing-site/ Phil -------------------- ... because the Solar System ain't gonna map itself.

Reading that paper about the radar testing is a bit disturbing. From what I read the unit was not tested in actual flight conditions but instead simply by sending it simulated echoes. I understand we cannot recreate Mars in drop tests but we can certainly put a unit in some sort of bouncing vibrating box hanging from a parachute under as tough conditions as we can manage and force it to report back its findings over very varied terrain. Anyone have any idea why that wasn't done if I'm reading things right?

From what I read the unit was not tested in actual flight conditions but instead simply by sending it simulated echoes. The radar unit was tested from cranes in Italy in static suspended tests and mounted on a helicopter in dynamic flight tests in Morocco (possibly also due to not that dissimilar terrain?). See here for pictures of the flight tests. |
