NASA’s Perseverance Rover Mission Getting in Shape for Launch

(Via NASA) Engineers working on NASA’s Mars 2020 Perseverance rover mission at Kennedy Space Center in Florida have begun the process of placing the Mars-bound rover and other spacecraft components into the configuration they’ll be in as they ride on top of the United Launch Alliance Atlas V rocket. Stacking spacecraft components on top of each…

An Opportunity From Above

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…

After 5,000 Sols We See the Face of Opportunity

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!

Opportunity Spots Phobos Skimming the Sun

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…

Opportunity Looks Back on Its Downhill Departure from Cape Tribulation

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…

A Look Back at Sojourner, the First Rover on Mars

The first mission to successfully* send a rover to Mars, NASA’s Mars Pathfinder, launched on Dec. 4, 1996. It was a “budget” Discovery mission designed to demonstrate a low-cost method for delivering a set of science instruments to Mars and sent the first remote-controlled vehicle to be used on another planet. Solar-powered and only a foot in height,…

Curiosity’s Tracks Are Gone With The Wind

Mars may have an atmosphere just 1% the density of Earth’s but it can still stir up enough of a breeze to quickly cover a rover’s tracks, as evidenced in the animation above. Captured by Curiosity’s downward-looking Mars Descent Imager (MARDI) camera on Jan. 23 and 24, 2017, the two pictures show an approximately 3-foot-wide…

Opportunity Enters Its “Teenage” Years on Mars

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…
