The eye in the sky sees all…especially when that eye is the HiRISE camera on the Mars Reconnaissance Orbiter! Here’s another great image – this time in color! – of the crater known as Santa Maria, taken from over 150 miles above the Martian surface by the MRO…and if you look carefully at the lower right portion of the crater rim you can see a small grey object that casts a bit of a shadow. That’s the rover Opportunity, which has been investigating the area around Santa Maria for the past several months and was using its robotic arm to take close-up shots of a small nearby rock when the image above was acquired.
I wonder if she got the feeling that she was being watched. 😉
On the left side of the image the rover’s tracks can be seen in the darker Martian soil extending off-frame. (For a full-size view of the area click here...the tracks are more obvious there.)
Opportunity is currently the only active robotic explorer on the surface of Mars. It has been steadily traveling across the relatively flat Meridiani Plains region toward the much larger Endeavour Crater, stopping occasionally to investigate interesting features such as rock outcroppings, standing meteorites and various craters – such as Santa Maria.
Opportunity completed its three-month prime mission on Mars in April 2004 and has been working extended missions since then. The Mars Reconnaissance Orbiter, which arrived at Mars on March 10, 2006, has also completed its prime mission and is currently operating an extended mission.
Opportunity’s sister rover, Spirit, fell silent over eleven months ago after becoming stuck in loose sand and losing its ability to maneuver. MER team engineers have been trying to regain contact with Spirit ever since but no signal has been detected as of yet. Opportunity, on the other hand, is fully operational and in good roving form. Not bad for a little ‘bot that was originally intended for a 90-day mission! She’s making us proud, working away all alone on Mars.
Well, not alone…she’s got a friend in the sky above who keeps a good eye on her. 🙂
