Spaceflight is Still Hard: Antares Explosion Destroys Station Supplies

This past Tuesday, October 28, at 6:22 p.m. EDT, an Orbital Sciences Antares rocket lifted off from the shorefront pad at NASA’s Wallops Space Flight Facility in Virginia, the Cygnus vehicle inside its fairing . The third of eight planned launches in Orbital Sciences’ $1.9-billion NASA contract, the Orb-3 mission was to deliver over 5,000 lbs of cargo to the International Space Station after a beautiful nighttime launch that would be visible to viewers up and down the U.S. East Coast.

Except, as you probably know by now, that’s not at all what happened.

Just six seconds after ignition and liftoff from the pad, a series of explosions ran through the Antares rocket. Ablaze, the 133-foot-tall stack stopped in midair and then fell back onto the pad in a fiery smear, where it and its contents of fuels and cargo detonated in an enormous explosion. It was incredible, it was catastrophic, it was awful.

This Is The First Photo Ever Taken of Earth From Space

The first photo of Earth from space was taken on Oct. 24, 1946 (Credit: White Sands Missile Range/Applied Physics Laboratory. HT to Smithsonian Air & Space.)

These days we get to see photos of our planet taken from space literally every day. Astronauts and cosmonauts living and working aboard the ISS, weather and Earth-observing satellites in various orbits, even distant spacecraft exploring other planets in our Solar System… all have captured images of Earth from near and far. But there was a time not that long ago when there were no pictures of Earth from space, when a view of the planet against the blackness of the cosmos was limited to the imagination of dreamers and artists and there was nothing but the Moon orbiting our world.

On October 24, 1946, — before Apollo, before Mercury, even before Sputnik — that was no longer the case.

The image above shows the first photo captured of Earth from space, taken by a camera mounted to a V-2 rocket that was launched from the White Sands Missile Range in New Mexico. Taken to the United States by the dozen from Germany after the end of World War II, V-2 (for “Vergeltungswaffe 2″) missiles were used by the US Army to improve on their own rocket designs and also by scientists who were permitted to fill their payloads with experiments.

Surprise: it can snow on Venus! (But it’s made of metal.)

Our neighboring planet Venus is pretty badass. Sulfuric acid-laden clouds, crushing atmospheric pressure, and broiling surface temperatures soaring to nearly 900 degrees Fahrenheit (480 degrees Celsius) make Earth’s “sister” world quite the alien horror show. And now there may be another strange phenomenon to add to Venus’ list of extreme oddities: heavy metal ferroelectric “snow” covering its highest mountain peaks — but, curiously, only up to a certain height.

NASA’s Opportunity rover shows us what a comet looks like from Mars

It may not look like much but it’s actually quite a lot: that bright smudge is Comet C/2013 A1 (Siding Spring) as it approached Mars to make its historic and much-anticipated close pass on Sunday, Oct. 19! The mountain-sized comet shot past Mars at an estimated distance of 88,000 miles traveling about 35 miles a second… that’s 20 times faster than a bullet fired from a 9mm handgun.

While the comet didn’t put on a big show in our sky here on Earth (although some photographers did capture it quite nicely in telescopes) the rovers on Mars and spacecraft in Martian orbit were keeping their electronic eyes on it… and NASA’s Opportunity rover, now nearly 11 years on Mars, was the first to send back a confirmed image!

Here’s Where ESA’s Philae Will Make the First Ever Landing on a Comet

Site J

The long-awaited deployment of the Philae lander, currently “piggybacked” aboard ESA’s Rosetta spacecraft orbiting the nucleus of Comet 67P/Churyumov-Gerasimenko, will occur in less than a month and we now have our best look yet at the area now green-lighted for touchdown. The picture above, made from two images acquired by Rosetta’s OSIRIS imaging instrument, shows a 500-meter circle centered on “Site J,” a spot on the comet’s “head” carefully chosen by mission scientists as the best place in which Philae should land, explore, and ultimately travel around the Sun for the rest of its days. And as of yesterday Oct. 15, it’s a GO!

Nobody Makes a Picture of Mars Quite Like MOM

If you’re loving this fantastic image of the Red Planet as much as I am, then be sure to give thanks to MOM!

Don’t call home just yet though; this is a view from India’s Mars Orbiter Mission – MOM for short – which successfully entered orbit around Mars on September 24 after a ten-month journey to meet up with our neighboring planet.

(Of course if you want to call your own mom I’m sure she’d love to hear your voice.)

Spacecraft’s Selfie is Photobombed by a Comet

In-situ spacecraft “selfies” are always a treat and this one is awesome times two: taken by the Philae lander piggybacked onto ESA’s Rosetta, it shows one of the spacecraft’s 14-meter-long (46-foot) solar arrays glinting with reflected sunlight while off in the distance is the “rubber duckie” Comet 67P/Churyumov-Gerasimenko!
