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. 😉
In November 1964 NASA launched Mariner 4, the fourth of its ambitious series of robotic explorations of our three inner planet neighbors. Mariner 1 was lost during launch; Mariner 2 successfully flew past Venus; Mariner 3 failed to deploy; but on July 14–15, 1965, the 575-lb Mariner 4 became the first spacecraft to fly past Mars and capture close-up images of another planet from space.
Of course the pictures that Mariner 4 captured were in greyscale and not like the beautiful color views we are used to seeing from spacecraft today. But thanks to one creative scientist at NASA (and a box of crayons) our first scenes of Mars from space were in brilliant color.
This animation is comprised of three images acquired by ESA’s Mars Express spacecraft on Sept. 12, 2017 with its High Resolution Stereo Camera (HRSC). It shows parts of the grooved and pitted surface of Phobos, the larger of Mars’ two natural satellites.
Can you feel the heat? NASA’s Mars Odyssey can see it! This is an image of Mars’ smaller moon Deimos, captured with Odyssey’s THEMIS (Thermal Emission Imaging System) instrument on Feb. 15, 2018. Part of the 7-mile-wide Moon was in shadow, but the sunlit surface area reached temperatures up to 200 K (that’s still pretty cold for us, though… –100ºF / -73ºC!)
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!
