Titan’s Cold Hydrocarbon Lakes Could Be Naturally Carbonated—Er, Nitrogenated

At the north pole of Saturn’s largest moon Titan lie the largest (and only known) bodies of surface liquid in the Solar System outside of Earth. But on Titan, where temperatures are regularly around negative 300ºF, the liquid isn’t water but rather methane and ethane: compounds which are found as gases here on Earth. Titan’s seas and lakes are…

A Red Cent on a Red Planet: Curiosity’s 1909 Lincoln Penny

On March 9, 2017, NASA’s Curiosity rover took this picture with its turret-mounted MAHLI camera of the calibration target installed near the “shoulder” of its robotic arm. In addition to color chips and a metric line graph, the target also includes a U.S. coin: a 1909 Lincoln penny, adhered heads-up. Curiosity’s coin isn’t just for good luck…

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,…

Share Your Love of Cassini and Saturn with the World

Even if you’re feeling inundated by Valentine-themed everything at the moment, if you love space and you’re at all creative you’re definitely going to adore this. With Cassini in the final months of its 13 years at Saturn, NASA wants you to share your love of the spacecraft, its discoveries, and the ringed planet and its fascinating…

An Asteroid Approaches Your Planet: Roll a d10

It sounds like a surprise challenge posed by the “Dungeon Master” in a game of Dungeons & Dragons but this is sort of what happened on a cosmic scale on Feb. 6, 2017, when the 200-meter (656-foot) -wide asteroid 2017 BQ6 passed by Earth. Using the radar imaging capabilities of the giant 70-meter antenna at…

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…

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…

Ceres’ Bright Spot Looks Like a Giant Zit

After more than a dozen years of head-scratching we finally have our first really good look at the weird bright spot on Ceres, thanks to NASA’s Dawn spacecraft and its low-altitude mapping orbit (aka LAMO) around the dwarf planet. Appearing from 240 miles up as a dome covered in cracks and rising from the surrounding darker…

This Asteroid Will Come Eerily Close to Earth on Halloween

Yes, it’s true: a rather not-so-tiny near-Earth asteroid SKULL-SHAPED ZOMBIE COMET (see below) 2015 TB145 will make a relatively close pass by our dear planet Earth on October 31, aka Halloween — the day when certain beliefs profess that the veil separating the worlds of the living and the dead is at its thinnest, allowing spiritual and even physical interaction to occur…
