A crater of cosmic coincidence has formed on Mars and it has Star Trek fans down here on Earth going wild.

A chevron captured by NASA's Mars Reconnaissance Orbiter in the southeast Hellas Planitia region of Mars looks suspiciously like Star Trek's Starfleet Command symbol, representing the fictional intergalactic diplomacy organization we know and love.

It's been three years since NASA announced its 3-D Printed Habitat Competition, sending designers and architects scrambling to imagine the best design for a home on Mars—one that could be constructed using materials already available on Earth's neighbor planet.

Now, Nasa has announced the top three finalists, and their designs are something else.

For 340 days, the world looked up to astronaut Scott Kelly as he documented his innovative year aboard the International Space Station (ISS). Kelly shared spectacular images and even some thank-you notes from 240 miles above the earth.

But Kelly's time in space was anything but fun and games. He was a crucial half of the two subjects of NASA's Twin Study.

Humankind has made leaps and bounds in aviation since the Wright brothers first took flight. While the makes and models have changed and improved over decades, one consistent aspect has been the straightforward, unbending structure of the wing.

Now, researchers at NASA and MIT are looking to change that.

Mars has intrigued us humans down here on Earth for centuries, and the Red Planet isn't out of surprises.

While much of the public focus is on Mars' water supply—present and prehistoric—this latest mystery doesn't hinge on a liquid, but a gas. Specifically: methane.

NASA scuttled its plans for its first all-female spacewalk because the agency doesn’t have enough spacesuits that fit the astronauts, forcing one of the two women on the mission, Anne McClain, to give up her spot to a male colleague. McClain, NASA said, thought a large-sized suit would be fine but after a spacewalk last week discovered that the medium-sized was a better fit.

“Anne trained in ‘M’ and ‘L’ and thought she could use a large but decided after [last] Friday’s spacewalk a medium fits better,” a Nasa spokeswoman, Stephanie Schierholz, said yesterday. NASA would stay on schedule because "it's safer and faster to change spacewalker assignments than reconfigure spacesuits."
