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…

Water Water Everywhere

Everyone knows that Earth is a “water-world,” with oceans covering 71% of its surface and at least as much contained within our planet’s mantle deep below its crust. But there’s also liquid water to be found elsewhere in the Solar System: on Mars, on the dwarf planets Ceres and Pluto, and also on the icy moons of Jupiter,…

History Is Made Today As Dawn Arrives At Ceres

It’s official – NASA’s Dawn spacecraft has arrived at the dwarf planet Ceres! Today, March 6 2015, at 7:39 a.m. EST (12:39 UTC) Dawn was captured by Ceres’ gravity at a distance of 38,000 miles (61,155 km). Mission controllers at JPL received a signal from the spacecraft at 8:36 a.m. EST (13:36 UTC) that Dawn was healthy and…

Latest Images of Ceres Show Its Bright Spot Is Actually Twins!

Here’s your weekly Ceres update! The dwarf planet’s features are coming into better and better focus for the approaching Dawn spacecraft, which will be captured by Ceres’ gravity on March 6. The image above is yet another “best-ever” of Ceres (as will be each one we see now), captured on Feb. 19, 2015, from a distance of…

Opportunity Celebrates 11 Years on Mars With a Grand Panorama

While we have been getting most of our daily images of Mars from NASA’s Curiosity rover over the past couple of years, we shouldn’t forget that there’s still another rover keeping busy on the Red Planet: Opportunity, one of the twin Mars Exploration Rovers (MER-B), still exploring after 11 years! To commemorate Opportunity’s upcoming landing…

Half-kilometer Asteroid to Pass Closely By on January 26

Just under two weeks from now, on Monday, Jan. 26, the 1/3-mile (0.5-km) -wide potentially hazardous asteroid 357439 (2004 BL86) will pass by Earth at 3.1 lunar distances, or 739,680 miles (1,190,400 km). While this may sound like a long way off, in the grand scheme of things it’s still a close pass… especially for…

Find Out How “Crazy Engineering” Is Getting Dawn to Ceres

Remember Dawn, the spacecraft that showed us our first close-up images of asteroid/protoplanet Vesta when it entered orbit back in 2011? Well Dawn is still going strong, having left Vesta behind and now closing in on its next target: Ceres, a full-fledged dwarf planet and, at about 600 miles (965 km) wide, the largest object in the main asteroid belt. Once…

An Ocean Beyond Earth: Europa Awaits

It’s no secret that Earth’s ocean is filled with life, much of it still a mystery or totally unknown to science. But what about the ocean on other worlds? I’m not talking about sci-fi planets or suspected alien Earths around other stars, but right here in our own solar system, where an ocean even deeper than ours lies…

Opportunity Breaks the Record for Extraterrestrial Roving

Well it’s official: after over a decade of roving on Mars, NASA’s Opportunity rover has surpassed the off-world driving record previously and proudly held by the Soviet Lunokhod 2 rover since 1973*! As of July 27, 2014, the tenacious solar-powered Opportunity racked 25.01 miles (40.25 kilometers) on its odometer as it traveled along the southern rim of…
