A wonderfully strange photo from Opportunity's exploration of Cape York, Endeavour Crater.

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.

It might surprise most people to learn that multitudes of knots tied in cords and thin ribbons have probably traveled on every interplanetary mission ever flown. If human civilization ends tomorrow, interplanetary landers, orbiters, and deep space probes will preserve evidence of both the oldest and newest of human technologies for thousands, if not millions of years.

OSIRIS-REx is will return a piece of the ancient asteroid 1999 RQ36, and it's up to you to come up with a name.

It was a surprise and delight to have our Icarus paper highlighted in Emily Lakdawalla's blog. Thanks for highlighting Uranus, since it has gotten, ahem, a bum rap over the years. Here's more about our discovery of the dark spot on Uranus.

HiRISE's best opportunity to view Curiosity so far came 12 days after landing, when the orbiter passed nearly directly overhead. The photo resolves amazing detail on the huge rover.

It's an active time in interplanetary exploration! Curiosity has begun roving Mars, and Opportunity's not wasting any time either. Dawn has just departed Vesta and begun the more than two-year cruise to Ceres. Juno is in the middle of a big deep-space maneuver, setting up next year's Earth flyby.

Yesterday, August 27th, 2012, was, in a sense, the 50th anniversary of interplanetary travel. Fifty years ago yesterday, Mariner 2 launched toward Venus, and became the first object to leave Earth and travel to another world.

Although Neil Armstrong may have passed away, his name will be part of human history forever.

Neil Armstrong changed the world. He was an excellent engineer and an outstanding pilot. He got the assignment to land a completely novel rocket machine on the Earth’s Moon, because he was the perfect man for the job: He could really fly; he had excellent judgment about the capabilities of his ship; and above all, he had a remarkable ability to keep his wits about him in extraordinarily dangerous situations.

If you've been obsessively checking the Curiosity raw images websites for new pictures from Mars, you might have noticed something weird: a bunch of Mastcam images and a few from MARDI that are black-and-white instead of color, and which have a peculiar checkerboard pattern.

NASA's Radiation Belt Storm Probes will shed new light on the Van Allen Radiation Belts, a dangerous region of space in our planet's backyard.

Space exploration is not just valuable to scientists; it is also popular with the public who pays taxes. And why not? The exploration of Mars is not only a search for signs of alien life. It is an exploration of the human future.
