3D printing has captured the imaginations of just about anyone who knows what it is -- even NASA, apparently.

The space agency is using a similar technology to create precise metal parts for its next heavy-lift rocket, which it hopes will eventually help take humans to Mars.

The method is called selective laser melting, or SLM, but it's not quite the same as printing up a sweet "Star Wars" chess set out of extruded plastic. It's more of a cross between 3D printing and some high-end, defense-grade awesome tech.… Read more

NASA and the European Space Agency say they have successfully tested an interplanetary communications protocol, with astronauts on the International Space Station using it to control a Lego robot in Germany.

The protocol is called Disruption Tolerant Networking (DTN), and one of its creators is Vint Cerf, who helped come up with the original Internet Protocol suite. NASA and the ESA said on Thursday that DTN may one day allow "internet-like communications" with spaceships and help support infrastructure on other planets.

"The demonstration showed the feasibility of using a new communications infrastructure to send commands to a … Read more

It has been almost 40 years since the Apollo 17 mission last landed a man on the moon. It may not take anywhere near that long before we send astronauts back to the moon's neighborhood.

Space.com reports that NASA is seriously looking at sending out a new manned moon mission with the purpose of creating a manned outpost beyond the far side of moon and eventually visiting an asteroid in 2025. This may not physically land a human on the moon, but it would establish a deep space outpost as a base for research and missions.… Read more

Even if you're outside the U.S., rocking the vote is relatively easy -- as long as you're on Earth. But how do you make your mark if you're an astronaut up above?

The International Space Station has been hosting international crews for 12 years, and there are now two Americans aboard: Sunita Williams and Kevin Ford.

While both voted in Russia before they left Earth, there are provisions for astronauts who want to vote from space. … Read more

You may or may not know that the International Space Station is visible from Earth with the naked eye. If you didn't know, NASA wants to make sure you do. The space agency has created a service that will send e-mail and text alerts when the ISS is above your location.

It's called "Spot the Station." The system allows you to give your e-mail address and receive notices when the ISS, the third brightest object in the sky after the sun and moon, is orbiting above your area. Given that the ISS passes over roughly 90 percent of the Earth's population, most people will have a chance to spot the space station sooner or later.… Read more

It's as if you've just strolled up to Curiosity on the surface of Mars and surprised the rover as -- convinced that everyone at Mission Control is on a coffee break -- it's decided to ditch the scientific research for a bit and build a martian sand castle instead.

One of the latest Curiosity images posted by NASA is a stunning self-portrait made up of 55 high-rez images taken by the rover's Mars Hand Lens Imager. The base of Mount Sharp serves as a dramatic backdrop, swooping up toward the right, and in front of the rover, you can see four hand-size holes in the ground where Curiosity had just started building its sand castle gathered scoops of martian dirt for analysis. The scoop site is poetically named "Rocknest."… Read more

KENNEDY SPACE CENTER, Fla. -- By dawn's early light today, the shuttle Atlantis was hauled out of the cavernous Vehicle Assembly Building for the last time, rolling not to the launch pad but to the spaceport Visitor Complex 10 miles away, where it will go on public display next year -- the last of the iconic winged orbiters to make the transition to Earth-bound museum duty.

Mounted atop a 76-wheel transporter, Atlantis was slowly rolled out of the VAB starting at 3:30 a.m. PT, cheered on by a crowd of several hundred spaceport workers; a throng of … Read more

Just in case your visual cortex hasn't been flooded with hurricane graphics yet, NASA has this interesting view of Sandy's interior.

The image was generated based on data gathered by the Tropical Rainfall Measuring Mission (TRMM) satellite, part of a mission jointly run with the Japan Aerospace Exploration Agency (JAXA).

Launched in 1997, the satellite can measure rainfall and cloud heights in tropical cyclones, which include hurricanes like Sandy and the typhoons that frequently lash the Japanese archipelago, such as Typhoon Tip, the largest of its kind on record. … Read more

In a major milestone for the space station program, a commercial cargo capsule loaded with nearly a ton of long-awaited experiment samples, broken components, and other gear returned to Earth on Sunday, plunging back through the atmosphere to a Pacific Ocean splashdown and wrapping up the spacecraft's first operational flight.

The SpaceX Dragon capsule is the first space station cargo ship since the shuttle capable of carrying large amounts of equipment both to and from the lab complex. As such, it restores a critical capability for NASA -- the return of experiment samples from the station -- along with … Read more
