"The Philae has landed!" Excitement over the Rosetta mission has been building for weeks, with tons of explanatory blog posts on what the lander is meant to find, helpful historical timelines, and an Astronaut Simulating the Comet Landing while on board the Space Station. At long last, the wait is over: European Space Agency’s Philae Spacecraft made an historic touchdown on comet 67P/Churyumov-Gerasimenko this week. The next day, it news broke that Rosetta's Philae Lander Is In Trouble. The probe is sending back data, but scientists aren’t sure where it landed or how long it’ll survive. Rosetta's little lander bounced a kilometer back into space before settling. Now it could run out of batteries.

But oh, the glorious photos it is sending back in the meantime! Photos make the space rock look small. It's actually enormous. Here's How Philae's Comet Compares to the Statue of Liberty and Eiffel Tower. Related: How Philae's Comet Compares To An Imperial Star Destroyer. Despite all this ocular proof of the successful landing, Alien "Cover-Up" Conspiracy Theories are already starting to Emerge. There are allegations that 67P is not a comet but alien object kept secret by NASA and European Space Agency. Yeah, right. Also: Apparently 67P/Churyumov-Gerasimenko is singing a mysterious "song" into space. And now you can Pilot Rosetta at Home to Land on a Comet and Study It With NASA's Comet Quest Game.

So: the Rosetta Mission is a True Space Odyssey. Here’s what it means, and what we’ll learn and why the Mission is Such a Big Deal. The comet 67P is a relic from the solar system’s birth: studying it will offer insight into Earth’s beginnings – and could avert future collisions.

"Claudia Alexander has spent the last 15 years of her life waiting for this moment: landing a spacecraft the size of a washing machine on the surface of a speeding comet."

Philae and Rosetta "live-tweeted" their separation, breaking a few Internet hearts in the process. But xkcd pretty much won the internet this week by live-cartooning the comet landing. See the collection here.

In the midst of the excitement, though, was a disappointment: one of the head ESA Scientists decided to wear a Shirt Covered in Gratuitous Sexy Chicks For the Livestream of this momentous landing, prompting numerous distressed tweets. If you're among those who can't see what the big deal is, here's Alice Bell in the Guardian eloquently explaining why women in science are annoyed at the scientist's clothing. Another blogger declared, "Science took a huge step forward today, and, thanks to one dumb fashion choice, one step back." And at the Washington Post, Rachel Feltman observed, "No one is saying that Taylor isn't a good scientist, or that he should be dragged through the mud for his miss-hap. But when these things happen, we need to talk about them -- and the men involved need to listen." Others helpfully offered alternative colorful and quirky shirts to wear for when you've just landed a spacecraft on a comet -- and even some comet-inspired jewelry, if you're so inclined. And on Friday, Rosetta Scientist Matt Taylor Apologized for his poor choice of shirt. Yay!

So much for comets. On the shameless self-promotion front, I have a new article up at Quanta on how Multiverse Collisions May Dot the Sky: Early in cosmic history, our universe may have bumped into another — a primordial clash that could have left traces in the Big Bang’s afterglow. (It's the second of a two-part series on the multiverse; here is Part 1 by Peter Byrne and Natalie Wolchover.) I also wrote a two-part post for NOVA's physics blog: There’s More Than One Way To Hunt For Gravitational Waves (Part 1 and Part 2). This week on Virtually Speaking Science, I chatted with Glen Whitman and Jim Dow about economic recovery after the zombie apocalypse, analyzing vampire investment strategies, illuminating the market forces that affect vampire-human romances. If you missed this fascinating conversation, it's archived here on Blog Talk Radio. And Jen-Luc Piquant highly recommends the collection of essays Whitman and Dow edited, Economics of the Undead: Zombies, Vampires, and the Dismal Science.
