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 Endeavour crater.
Not too shabby for a robot that was only originally intended to operate for 3 months!
If you’re a heavy metal fan then you’ll love this: this shiny, lumpy rock spotted by NASA’s Curiosity rover is made mostly of iron — and came from outer space! Dubbed “Lebanon” it’s a stony iron meteorite, similar to ones found in years past by the Spirit and Opportunity rovers, but is considerably larger than any of the ones they came across. In fact, at 2 meters (6.5 feet) wide, Lebanon is the biggest meteorite ever discovered on Mars!
Whether you’re a trend-loving hipster, a breakfast lover, or just fan of meat products in general, you’d have to agree that it does look like a giant piece of bacon* running across the image above. And while the color and shape seems about right, the size and temperature is a bit off — that’d be a piece of fried pork 25 miles wide and -300ºF!
All kidding aside, this is actually a newly-released picture of the frozen surface of Jupiter’s moon Europa, made from images acquired by NASA’s Galileo spacecraft in 1997 and 1998. The dark coloration of the river-like bands is thought to be the result of organic compounds staining the water ice that has welled up from the moon’s deep subsurface ocean… all the more reason that yes, we really should attempt a landing there in the very near future!
*No pigs were harmed in the production of this image.
Telescope twin powers: ACTIVATE! Form of… an asteroid?
Okay, so the telescopes involved aren’t twins — one is a giant 70-meter dish in California’s Mojave Desert and the other is a 305-meter behemoth high in the Puerto Rican rain forest — they did combine their powers to image the passing asteroid 2014 HQ124 on June 8 as it came to within about 3 lunar distances, obtaining some of the highest-resolution data of a near-Earth asteroid ever.
Before the pass this object was being called “the beast,” but once astronomers bounced some radar off it its true beauty shined through. Read more in my Discovery News article here.

While it may not be a true “smoking gun” (there have been four and a half billion years of cooling off, after all!) scientists in Germany have found further support for the currently accepted scenario of the origin of our Moon, based on chemical analysis of rocks brought back by Apollo astronauts. (And yes, we really went to the Moon.)
It used to be said with confidence by even grade-school kids that the largest storm in the Solar System was Jupiter’s Great Red Spot, which has been churning for at least 350 years and could fit three Earths across it. And while it’s true that the GRS is a truly enormous hurricane by Earthly standards, these days it’s not as “great” as it used to be — over the past couple of decades the GRS has shrunk to only about a third of its former size.
“Recent Hubble Space Telescope observations confirm that the Great Red Spot (GRS) is now approximately 10,250 miles across, the smallest diameter we’ve ever measured,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
That equals about 16,500 kilometers, or about one and one-third Earths across. Which is still very big, yes, but nothing compared to what it once was!
This is something really special, and everyone should know about it, and so I’m doing my part and sharing it here but please feel free to pass it along yourself as well. We now have publicly-accessible, high-definition video of our planet coming in live from the Space Station, thanks to the High Definition Earth Viewing (HDEV) experiment aboard the ISS. Activated April 30 of this year, HDEV consists of four cameras contained within a single housing mounted on the External Payload Facility of the European Space Agency’s Columbus module. When the experiment is running these cameras take actual video of the planet as the ISS passes overhead in real time (not a recording or time-lapse) which is simultaneously aired live online FOR EVERYONE TO SEE.
It’s beautiful, it’s mesmerizing, it’s fascinating (when it’s on, of course) and you really just need to see it for yourself.
