Both Spirit and Opportunity are still suffering under incredibly dark skies, but, amazingly, they are both "power-positive," meaning that they are managing to produce enough power from the limited amount of sunlight to keep the batteries fully charged.
Today, New Scientist and researcher Ron Levin retracted the "puddles on Mars" claim in the face of evidence that the "puddles" were on sloping surfaces. I've updated my original blog entry in response to the claim to that effect.
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.
According to a press release issued this morning by the National Oceanic and Atmospheric Administration, the enormous solar flare that erupted on December 5 and 6 last year was accompanied by an intense radio burst that caused large numbers of Global Positioning System recivers to stop tracking the signal from the orbiting GPS satellites.
There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!
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.
A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.
