Last Monday, May 13, the Suomi NPP satellite captured a fascinating image of Tropical Cyclone Mahasen as it moved northeast over the Bay of Bengal. The clouds of the storm itself weren’t optically visible in the darkness of a nearly new Moon, but lightning flashes within it were… as well as the eerie ripples of atmospheric gravity waves spreading outwards from its center.

The name is Peake. Timothy Peake. And he’s set to follow in the (fictional) footsteps of fellow British citizen James Bond with a stay on a space station.

In 2015, Peake will be the first British citizen to live for six months on the International Space Station. He’ll be a part of the Expedition 46/47 crew. NASA hasn’t publicly named all of his seatmates yet, but expect a lot of excitement across the former Empire when Peake has his turn.

Put The Aurora Borealis In Your Ear

Do the aurorae makes sounds? That’s been a subject of discussion — and contention — among people who watch the sky. While most of us will never hear the aurora borealis directly, there’s help out there in the form of a little handheld radio. It’s called a VLF receiver and guarantees you an earful the next time the aurora erupts.

Video Caption: This JPL video shows the complicated choreography to get drill samples to Curiosity’s instruments as she prepares for 2nd drilling at “Cumberland.” See where “Cumberland” is located in our panoramic photo mosaic below.

It’s time at last for “Drill, Baby, Drill!” – Martian Style.

Ever wonder how Curiosity “Does It”

Well, check out this enlightening and cool new NASA video for an exquisitely detailed demonstration of just how Curiosity shakes, rattles and rolls on the Red Planet and swallows that mysterious Martian powder. [click to continue…]

Opportunity pops a ‘wheelie’ on May 15, 2013 (Sol 3308) and then made history by driving further to the mountain ahead on the next day, May 16 (Sol 3309), to establish a new American driving record for a vehicle on another world.

Now more than 9 years and counting into her planned mere 90 day mission to Mars, NASA’s legendary Opportunity rover has smashed past another space milestone and established a new distance driving record for an American vehicle on another world this week.

On Thursday, May 16, the long-lived Opportunity drove another 263 feet (80 meters) on Mars – bringing her total odometry since landing on 24 January 2004 to 22.220 miles (35.760 kilometers) – and broke through the 40 year old driving record set back in December 1972 by Apollo 17 astronauts Eugene Cernan and Harrison Schmitt.
