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…

These Are Our Best Pictures of Mars’ Smallest Moon

Mars isn’t a planet well-known for its natural satellites but it actually does have two small moons. The larger, Phobos, is an irregularly-shaped, heavily grooved and cratered world only about 17 miles (27 km) across at its widest. It orbits Mars so closely that it completes 3 orbits every day, and isn’t even visible from…

HiRISE Eyes Fresh Craters on Mars

Just to remind you that things are still indeed going “boom” in our Solar System, here is a cluster of fresh craters on Mars created by an impact that occurred sometime between 2008 and 2014. The craters are a result of a meteorite that broke apart during entry, striking the surface as fragments within a localized area….

This is Jupiter Seen from Mars

The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) is specifically designed to take super high-resolution images of the surface of Mars but it also does a pretty darn good job capturing pictures of other objects too—like Jupiter and its Galilean moons, several hundred million miles away! The image above was captured in expanded color (that is,…

This is Earth and the Moon Seen From Mars

Here’s a view of our home planet and its lovely Moon captured from 127 million miles away by NASA’s Mars Reconnaissance Orbiter on November 20, 2016. The sunlit part of Earth shows eastern Asia, the Indian Ocean, and Australia with ice-covered Antarctica visible as a bright white spot. The Moon has been brightened in this image, since it would…

A Craterful of Cracks

Here’s a view of a section of a crater on Mars filled with a lacework of bright spidery fractures, acquired on Sept. 20, 2015 with the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter. The crater is approximately 3 miles (5 km) wide and located in Mars’ north polar region, and its old, infilled interior has undergone countless millennia…

NASA Sciences the Sh*t Out of Mars, Finds Water

So on the same week that the highly-anticipated film “The Martian” opens in U.S. theaters (you are going to go see it, I assume) NASA revealed the latest discovery regarding the Red Planet: there is water on the surface there, salty rivulets that periodically run down steep slopes in Hale Crater and stain its sands with dark…

Curious Stains on Mars’ Summer Slopes Continue to be Seen

As the midsummer Sun beats down on the southern mountains of Mars, bringing daytime temperatures soaring up to a balmy 25ºC (77ºF), some of their slopes become darkened with long, rusty stains that may be the result of water seeping out from just below the surface. The image above, captured by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Feb….

The Details Are In The Dunes

And what details! This image, acquired by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Jan. 24, 2014, shows rippled dunes in Mars’ southern hemisphere, coated with a fall dusting of seasonal carbon dioxide frost. With the Sun just five degrees above the horizon, the surface detail captured by HiRISE is simply exquisite. Be…

Mars Gets a Brand New Crater

If you count at least slightly over two years old as “brand new” then yes, this one is certainly that! Seen above in an image taken by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Nov. 19, 2013, a 100-foot-wide (30-meter) crater is surrounded by bright rays of ejected material and blown-clear surface. Since…

New Mars Rover is a Litterbug!

Only two days on Mars and Curiosity has already made a mess! 🙂 The various components from MSL’s descent and landing process have been spotted by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter, scattered in the vicinity of Curiosity within Gale crater. MSL’s heat shield, parachute, back shell and sky crane (with a very…
