Mars Photo of the Day - Jan 14 2012

Today's Image of Mars was taken in early 2007 by HiRISE after there was speculation that this crater was the landing site of the lost Beagle 2 lander.

The Beagle 2 lander detached from the Mars Express orbiter in December 2003, but  all communication was lost with the lander six days before atmospheric entry. Because there was no telemetry being sent back during its descent scientists cannot be sure where is landed. It is unlikely that the entry, descent, and landing sequence (EDL) was nominal, but just in case, the HiRISE team has been examining the area it was expected to land in hopes of finding it.

This particular image was taken in response to reports that the Beagle 2 lander had actually been found within this crater. One of the reports, from the United Kingdom's The Times referenced the Beagle 2 chief scientist, Colin Pillinger, saying
They suggest that the probe was lost because of cruel luck as it touched down in one of the worst possible places for a soft and successful landing. Rather than dropping to the surface on a flat plain, it appears to have first struck the downslope of a small crater about 18.5m (60ft) in diameter, before crashing into its opposite wall, bouncing several times around the rim and eventually coming to rest at the bottom. Even if the gas bags that were meant to cushion its impact were fully inflated, and there is some evidence that they were not, their design would not have allowed them to protect the probe properly under these unlikely circumstances.
Unfortunately these claims were unsubstantiated, as you can see from the below image of the crater in question. To this day the HiRISE team has continued to look for all the lost Mars landers, including Beagle 2 in hopes that finding them would help to understand the reason for the malfunction and allow future missions to be better prepared.

Mars Photo of the Day - Jan 13 2012

Today we're going to take a look at 15 different images of Mars taken by the Mars Reconnaissance Orbiter's HiRISE camera. These images show the parachute and backshell of the six successful Mars Landers: Viking I, Viking 2, Mars Pathfinder, Spirit, Opportunity, and Phoenix

It is easy to spot these landers and their associated hardware because we know exactly where they landed. We still haven't been able to find the failed landers, Mars 2, Mars 3, Mars 6, Beagle 2, and Mars Polar Lander, despite extensive searching. Finding the failed landers is much harder because we don't know where they land and we have to guess according to their last known positions as they approached Mars.

When trying to identify a lander the easiest things to identify are the parachute and the large protective backshell. As you can see from most the of the below images, the parachute is the easiest thing to see. The lander itself is relatively small and hard to see. All but one (Mars 2) of the lost landers are believed to have deployed their parachute so they should theoretically be visible if in an area imaged by HiRISE.
