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.

"Schiaparelli Mars probe's parachute 'jettisoned too early'"
QUOTE Europe's Schiaparelli lander did not behave as expected as it headed down to the surface of Mars on Wednesday. QUOTE But it is at the end of this parachute phase that the data indicates unusual behaviour. Not only is the chute jettisoned earlier than called for in the predicted timeline, but the retrorockets that were due to switch on immediately afterwards, fire for just three or four seconds. They were expected to fire for a good 30 seconds. In the downlinked telemetry, Schiaparelli is seen to continue transmitting a radio signal for 19 seconds after the apparent thruster shutoff. http://www.bbc.com/news/science-environment-37715202 |
