Buzz Aldrin, 86, was medically evacuated from a tourist trip to Antarctica after he began suffering from altitude sickness and shortness of breath. No one panic. After a week-long stay in a New Zealand hospital, the second man to walk on the moon is doing just fine.

With his passing earlier today, John Glenn is being remembered as not only the first American to orbit the Earth, but also the oldest. Here's why NASA sent a 77-year-old man into space, and how his historic trip set space science forward.
Last week, the Cassini spacecraft began a series of dramatic, "ring-grazing orbits" that will see it fly high over Saturn's poles before diving perilously close to the gas giant's rings. Now, NASA has received back the first images from this exciting chapter in Cassini's last year of life — and they do not disappoint.
You would never buy a hundred million-dollar computer without a repair plan, but that's exactly what NASA does when it sends costly satellites into space. To ensure that its prized eyes-in-the-sky don't become the solar system's most expensive e-waste, the space agency is now building a robot capable of repairing and refuelling satellites in orbit.
During a recent trip to Antarctica, where the 86 year old became the oldest man to reach the south pole, second man to walk on the moon Buzz Aldrin suffered from fluid on his lungs.
Transferred to a hospital in Christchurch, his treatment is being undertaken by a doctor who happens to share a name with another "starman": the late David Bowie.
Video: Going to space is definitely one of the coolest things a human could ever do, but damn if it doesn't do a doozy to your body. If you were able to spend time in space, your bones would become brittle, your leg and back muscles would wither away, the back of your eyeballs might flatten and your heart could lose mass and become more spherical. None of that is good.
In case Schiaparelli's crash-landing left you thinking the European Space Agency's ExoMars mission was a bust, rest assured it wasn't. The mission's scientific workhorse — its Trace Gas Orbiter (TGO) — is performing beautifully, as evidenced by the first images and splashes of data ESA has now received back from the Red Planet.
Obviously, fire is pretty dangerous. To say fire is pretty dangerous in space, however, is a gross understatement. And that's basically the story of why NASA decided to do some space fire tests, with a range of materials.
Lucky for us (because space fire is ridiculously cool) footage of the tests were released by NASA - and you can watch them here.
When you sit down to assemble a puzzle, even one with thousands of pieces, you at least have a photo of the completed image to work towards. But thanks to some clever mathematics, this Infinite Galaxy Puzzle can be assembled in any direction, or in any shape, leaving you without much guidance on how to put it together.
If we ever get proof of past life on Mars, it will come in the form of biosignatures, fingerprints that could only have been left by living organisms. We're a long way from finding that smoking gun evidence, but an analysis of silica minerals discovered by NASA's Spirit rover pushes us one step closer. Because of their similarity to silica deposits shaped by microbial life on Earth, these intriguing Martian minerals are now being called a "potential biosignature".
Placed on Earth, it would stretch from Washington DC to New York to Denver. Larger than the Grand Canyon, wider and deeper than East Africa's Great Rift Valley, Mercury's newly-discovered "Great Valley" boggles the imagination. But it's more than size that makes this geologic feature remarkable. The Great Valley may be our best evidence that Mercury's entire crust is contracting.
Four billion years ago, an asteroid the size of Manhattan smacked into Pluto, punching out a crater that filled up with ice from above and water from below, eventually becoming so heavy it caused the entire planet to tip over.
The men and women who came up with the 88 officially-recognised constellations definitely had richer imaginations than I do. I don't see animals, dragons and centaurs when I look at the night sky, and I'm generally OK with that. Still, when I came across this new celestial map, I got a small taste of the wonder the ancient Greeks must have felt gazing at the stars.
