Human beings reached a new space exploration milestone this week: landing the Rosetta mission's Philae probe on a comet some 316 million miles from Earth.
This is the first time we've landed a human-made thing on a freaking comet, and it's blowing our minds. How did the scientists and engineers at ESA
and their partners at NASA
pull it off? This ESA video and GIF explain it all, in chronological order, over the 12-year period from mission launch to Philae's touchdown
This animation tracks Rosetta's journey through the Solar System, using gravity slingshots from Earth and Mars to reach its final destination: Comet 67P/Churyumov--Gerasimenko. Rosetta made three flybys of Earth, on 4 March 2005, 13 November 2007 and 13 November 2009, and one of Mars, on 25 February 2007. Rosetta has also visited two asteroids, taking extensive close-up images of 2867 Steins on 5 September 2008 and 21 Lutetia on 10 July 2010. Once the spacecraft is woken up from deep space hibernation on 20 January 2014, it will head for rendezvous with the comet in May. In November the Philae probe will be deployed to the comet surface. Rosetta will follow the comet to its closest distance to the Sun on 13 August 2015 and as it moves back towards the outer Solar System. The nominal mission end is December 2015.
Here's the Rosetta mission website.
At the time of this blog post, scientists have re-established contact with the Rosetta probe, but it appears to be stuck in a crater where it cannot get enough sunlight to power up its solar panels. As with so many gadgets back here on earth, the biggest bummer is battery life.
If you vomit, do be considerate and try not to let it land on the moon. [via Metafilter]
Astronaut Shane Kimbrough, commander of the Expedition 50 expedition to the International Space Station, explains how to make a peanut butter and jelly sandwich in space. He returned from the ISS earlier this month after six months in orbit.
That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
Yeah, Bluetooth audio is pretty common these days, so why should you care about these earbuds? Look how happy that woman up above looks. She’s got FRESHeBUDS in. Boom. There’s your reason. She’s also at the beach and it appears to be a very nice day.But for the sake of promotion, wireless earbuds are fast becoming the […]
“Gets stuff done,” is a good way to be described by anybody. Especially by coworkers or bosses. Because whether you’re in finance or a children’s librarian, stuff needs to get done. But how do you make sure stuff gets done? You definitely can’t do all the stuff yourself, unless your company/organization/government office consists entirely of you. And […]
