There's no crying in baseball, and there's no crying in space.

While zero gravity doesn't have an impact on tears forming, it has an effect on if they fall -- and they don't. The water that builds up in your eyes from crying will stay there until the bubble gets so big it moves to another spot on your face, or it's removed. It's not very pretty or graceful.

Astronauts in the International Space Station have already explained how to clip fingernails and play guitar while orbiting 240 miles above the Earth. But what about all those other questions people may have about life in space?

They can be answered in an upcoming Google+ Hangout with three of the astronauts aboard the ISS -- Kevin Ford, Tom Marshburn, and Chris Hadfield.

NASA announced today that it is hosting its first live Google+ Hangout from space. It's to happen from 11 a.m. to 12 p.m. EST on February 22. The space agency is accepting questions in advance … Read more

Around 2015, NASA plans to incorporate a spacesuit that amusingly looks like the one worn by Buzz Lightyear in "Toy Story" -- sans the shiny laser beam.

Before you laugh, know that these new digs aren't toy dressings; the Z-1 NASA spacesuit offers a plethora of advantages compared with the space agency's previous designs. Think of it as the baseline architecture for future NASA spacesuits. … 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

The X1 Robotic Exoskeleton looks like a cross between the legs of a Stormtrooper and a Transformer. The suit is a spinoff from NASA's Robonaut 2 humanoid robot project.

The X1 is focused on either helping or hindering a person's legs, depending on its job description. When it's set to inhibit, the X1 resists movement and could be used to help astronauts exercise in space. When it's set to help, it could be used to assist paraplegics and others with lower body injuries with walking.

Four motorized joints and six passive joints give the 57-pound suit a good range of motion. It also gives it some nice Iron Man flavor, minus the propulsion feet.… Read more

The scientists aboard the International Space Station "have the best view in the solar system," videographer Alex Rivest says. Maybe that is why he created this time-lapse video of exactly what the scientists see so people around the world can also gaze at the same view.

Hovering close to Earth and completing 15 orbits per day, the ISS provides dozens of photos and videos of the views it records -- the same stunning scenes captured in Rivest's video. The habitable satellite tracks rolling scenes of the multi-colored planet with images of long winding rivers, high mountain ranges, … Read more

As far as the United States was concerned, John Glenn's Feb. 20, 1962, flight aboard Friendship 7 could not have been more important.

Less than a year earlier, Soviet cosmonaut Yuri Gagarin had become the first human in space, and by the time of Glenn's launch, Americans Alan Shepard and Gus Grissom had already made their way into the heavens, if only briefly.

But with his 4 hour, 56 minute flight, Glenn became the first American to orbit the Earth, doing so three times at an altitude of up to 162 statute miles and speeds of up to … Read more

What do you do if you're an injured astronaut and your doctor absolutely refuses to make Mars calls?

Well, the European Space Agency is trying to address that question. The ESA is testing a wearable augmented-reality device that might one day enable astronauts who aren't doctors to perform surgery on ailing colleagues.

Astronauts haven't whipped out the scalpels just yet--the device is currently being tested as a tool for ultrasound examinations that let users look patients over and diagnose a medical condition. But the agency said in a recent post to its Web site that "in principle [it] could guide other procedures."

In a nutshell, the device--the Computer Assisted Medical Diagnosis and Surgery System, or Camdass--works as follows. While moving an ultrasound probe along the patient, the user wears a headset that displays a 3D image of healthy tissue along with the ultrasound images of the patient.

The device, according to the ESA, "precisely [combines] computer-generated graphics with the wearer's view." Hence, differences--and problems--can be spotted.… Read more

Jobs are scarce.

Might you therefore consider a career change that will take you not merely 1,000 miles from where you live, but hundreds of thousands of miles? Yes, to a place where no one can bully you, no one can nag you and everyone will look up to you.

Then NASA would like you to watch the video I've embedded below and apply online. This recruitment tool, posted by NASA yesterday to YouTube, shows just how sexy working in stellar conditions can be.

You get to drive cool concept cars. You get to take business trips to … Read more
