There was great news last night from Mars Exploration Rover mission operations: Spirit seems to have enjoyed another
Today, New Scientist and researcher Ron Levin retracted the
Today's set of image releases from the Mars Reconnaissance Orbiter HiRISE team included this one, of a fairly bland-looking lava plain to the northeast of Arsia Mons. Bland, that is, except for a black spot in the center.
Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.
This amazing view was captured by the CIVA camera on Rosetta's Philae lander just four minutes before its closest approach to Mars on February 25, 2007. The spacecraft was only 1,000 kilometers above the planet.
It's easy to forget that Mars is another such world with cloudy weather and seasonally varying climate. This lovely image release from the CRISM instrument on Mars Reconnaissance Orbiter brings that point home.
I've just posted a very detailed timeline of New Horizons' encounter with Jupiter -- take a look!
New Horizons' Jupiter encounter is officially underway!
This week's releases from the Mars Odyssey THEMIS team included a gorgeous one of the layered interior of Gale crater.
I just wanted to point out a couple of new items on the website.
Get used to this view of Home Plate and Husband Hill, because Spirit will be seeing a lot of it over the next 8 months, whenever power levels permit the rover to eke a little bit of science activity out of the day.
There was a big news splash about two articles that appeared in Nature about Mars Exploration Rover Opportunity's landing site. The articles suggest two theories for the formation of the layered sulfur-rich deposits at Meridiani Planum that do not involve standing liquid water.
Back in August, there was a false alarm being circulated by email that Mars was going to be super-close to Earth on August 27.
I received the following question by email last week:
Apparently there is a bogus email circulating around the Web with the following text:
During April 2005, the Mars Global Surveyor happened to pass relatively close to Odyssey and Mars Express. What resulted were remarkably clear pictures of human-made spacecraft orbiting and alien world.
NASA Headquarters issued a press release late yesterday announcing that the agency is memorializing the Apollo 1 crew -- Gus Grissom, Ed White and Roger Chaffee -- by naming the hills surrounding the first Mars Exploration Rover Spirit's landing site after the three astronauts.
Although it did appear from the very first images returned that the second Mars Exploration Rover had landed inside a small crater when it arrived at Meridiani Planum last Saturday night, that belief was confirmed with further analysis yesterday.
