Wanted: Reusable Rockets For NASA Research

Reusable rockets just went from a party trick to a research necessity. Have a rocket you can launch, land safely and launch again? NASA wants you, now.

Astronaut Scott Kelly On Liquid Salt, A Stinky Station And Sleeping In Freefall

There are lots of things most of us never contemplate when we fantasise about living in space. What happens to your arms when they don’t naturally fall at your sides? Do you keep your calluses when you aren’t walking? What’s it like to sleep in free fall?

Image Cache: The US East Coast just got walloped by a record-breaking winter storm. But sometimes, words simply can’t do justice to the magnitude of a meteorological event. You need images taken from 400km up.

NASA Has Completed Welding Together The Orion Spacecraft's Crew Module

The launch of NASA’s Orion Spacecraft isn’t slated for another two years, but preparations are well underway for the first mission into deep space: engineers have just completed welding together the Orion crew module.

Doomed Stars Glisten Like Diamonds In Latest Hubble Photo

Behold Trumpler 14, a dazzling star cluster located 8000 light-years from Earth. Situated within the Carina Nebula, it’s home to one of the highest concentrations of massive, bright stars in the Milky Way. But as spectacular as these stellar objects appear be, their majestic appearance comes at a price.

How Will A New Clock Keep Good Time Even In Deep Space?

Navigating in deep space is tricky, particularly when you need to keep up interplanetary synchronised clocks. NASA is convinced we can do better with a new atomic clock they’re testing in orbit this year. Here’s how it works, as illustrated by an adorably consternated second hand.

The First Space Flower Bloomed Decades Ago, Not This Week

This week was full of lessons. Lesson One: Never trust an astronaut. Lesson Two: Everyone loves flowers. Lesson Three: We’ve grown a lot of plants in space.

2015 Shattered All Temperature Records, And It Wasn't Just El Niño

In a joint statement this morning, NASA and NOAA confirmed that 2015 was the hottest year on record by a huge margin. We basically knew this — scientists have been calling it since at least July — but now that the official numbers are in, we can see just how wacky a year it was.

JPL Rocket Scientist Shows Why He's The Right Kind Of Crazy

When NASA’s Curiosity rover landed on Mars in August 2012, millions of people across the globe tuned in to watch. It was the culmination of nine long years of effort — and it went off without a hitch. In particular, we marvelled at the ingenious method designed by the engineers at the Jet Propulsion Laboratory to lower the one-ton rover onto the red planet’s surface: a hovering sky crane powered by booster rockets.
