To commemorate the 12th anniversary of NASA’s Mars Reconnaissance Orbiter at Mars (March 10, 2006) and the still-roving Opportunity, below is an edited version of an article I wrote back in 2011 showing Opportunity imaged by MRO’s HiRISE camera.
The eye in the sky sees all…especially when that eye is the HiRISE camera on the Mars Reconnaissance Orbiter! Here’s an image of a 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. 😉
It’s finally happened—after over 14 years on Mars (14!!!) NASA’s Opportunity rover has turned its arm-mounted camera around to take a look at itself, giving us the very first true “selfie” of the Mars Exploration Rover mission! Hello Opportunity!
It may be in its 14th year on Mars but Opportunity still has some surprises to show us—like this, a series of images captured on May 3, 2017 showing the Sun as seen from Mars. But that’s not the special part: see the change in brightness along the Sun’s edge near the end? That was a brief transit of Phobos, the largest (and nearest) of Mars’ two moons!
Can’t see it very well? It’s quick, I know—so check out a cropped and enlarged version below:
It’s all downhill from here! (Well not really, but it was for a little while when Opportunity was at the top of that hill!) The image above is a mosaic I assembled from six color-composites, each made from three separate images acquired in near-infrared, green, and near-ultraviolet color wavelengths on April 21, 2017 (mission sol 4707). It’s been adjusted to appear in approximate true color to what the scene might look like to a human standing on Mars. The view shows a ridge called “Rocheport” located on the western rim of Endeavour Crater (the interior of which would be toward the right in this image) which was the final segment of Opportunity’s last target region of exploration, Cape Tribulation. Opportunity’s wheel tracks can be seen at the bottom center, heading back up the ridge and zig-zagging toward the top (detail below).
Today marks the start of the “teen years” on Mars for NASA’s Opportunity rover — it’s been busy exploring, studying, and traveling across the planet’s surface for 13 years now and still going strong! Launched July 7, 2003, the rover is currently in its 4,624th sol of operations — pretty impressive for a mission that was initially only planned to last 90 days. (I suppose it’s OK if Opportunity wants to get a little bit of an attitude now, seeing as she’s such an overachieving teenager!) The video below was recently released by NASA’s Jet Propulsion Laboratory in Pasadena and features some of the talented engineers and scientists who work with the Opportunity rover on a daily basis.
