Latest Curiosity images from Mars

August 7, 2012

by yaska77

We promised you images and here are the latest batch from NASA JPL, sent from Curiosity over the last couple of days. We start first though with a fantastic image captured by the Mars Reconnaissance Orbiter and it’s HiRISE camera!

This image was taken just moments after Curiosity’s descent speed had slowed from thousands of kilometers per hour to just hundreds (click to enlarge) Credit: NASA/JPL-Caltech

In the expanded view you can see the band details on the “supersonic” parachute, and even the hole in the centre, as Curiosity heads towards a famous landing! When fully deployed the craft experienced over 9G of force as it slowed.

The image above was obtained by the Mars Descent Imager instrument (known as MARDI) and shows the 15-foot (4.5-meter) diameter heat shield when it was about 50 feet (16 meters) from the spacecraft.

It was obtained two and a half minutes before touchdown on the surface of Mars and about three seconds after heat shield separation.

The rover’s shadow can be seen in the foreground above, and the dark bands beyond are dunes. Rising up in the distance is the peak of Mount Sharp (Aeolis Mons) at a height of about 3.4 miles, the base of which the Curiosity team will target as scientists believe it will hold clues to past environmental change.

In the distance, the image above shows the north wall and rim of the Gale Crater. The image is murky because the MAHLI’s removable dust cover is coated with dust blown onto the camera during the rover’s terminal descent.

Images taken without the dust cover in place are expected during checkout of the robotic arm in coming weeks (as the cover won’t be opened until around a week after landing).

Considering these images are the tip of what should become a very large iceberg, and Curiosity hasn’t yet properly woken up, there is so much promise and excitement surrounding Curiosity at the moment, and rightly so.

What fantastic times we live in :)

Well there’s no mention or images of the new Supernova spotted in a nearby galaxy in this weeks post or indeed any in any relating to this series. Nonetheless we resume the countdown with the (latest) positions 50-46*.

Latest Endeavour launch update

May 3, 2011

by yaska77

Work to replace and fully test an electrical distribution box in STS-134 Endeavour’s engine compartment will further delay the next launch attempt to at least 10th May, NASA advised yesterday.  An official launch date is only likely to be announced on Friday after the repairs are complete.

This tentative new date is based on a full review of the work needed to replace the faulty aft load control assembly.  This showed it would take longer than originally expected to complete repairs (and all required testing) in time to start a fresh countdown for a launch on Sunday.

The lift-off of Endeavour was scrubbed on Friday 29th April when telemetry showed hydraulic power system fuel line heaters were not working properly. Later tests determined the problem was with the aft load control assembly No. 2 in the Shuttle’s engine compartment.

NASA are hoping to extend Endeavour’s mission by up to two days to allow the crew more time to complete their objectives, but with the Russian Soyuz* capsule scheduled to detach from the ISS on 23rd May (returning 3 of the 6 ISS crew to Earth) this will depend entirely on which day Endeavour is able to launch on.
