ISS Astronauts Celebrate 'Cosmos' with Weightless Experiment in Space Station - Video



The new "Cosmos" science TV series on Fox has received an out-of-this-world from astronauts on the International Space Station in a new video showing how weightlessness works.

In the new video beamed from space, NASA astronaut Rick Mastracchio considers Isaac Newton's third law of motion - every action produces an equal and opposite reaction - and demonstrates how this works in microgravity, 260 miles (418 kilometers) above Earth.

To demonstrate this, Rick Mastracchio pushes his colleague and ISS Commander, Japanese astronaut Koichi Wakata, along with a model of NASA's now-retired space shuttle.

As Wakata and the model spacecraft float forward, Mastracchio drifts backwards.

"This is simple science but the more complex science we're doing here on the space station will help us bring real world benefits back to humanity on Earth, as well as take us further into the cosmos than ever before, including to an asteroid, the moon or on to Mars," Mastracchio said.

Astrophysicist Neil deGrasse Tyson, host of "Cosmos: A Spacetime Odyssey," introduced the video of his "friends in high places," saying, "when you're doing science, you have to do experiments."

Soyuz Spacecraft Returns Expedition 38 Space Station Crew to Earth

An American astronaut and two Russian cosmonauts made a snowy but safe landing on Earth late Monday (March 10), bringing their 5 1/2-month mission aboard the International Space Station to a successful close.

A Soyuz spacecraft carrying NASA astronaut Mike Hopkins and Russian cosmonauts Oleg Kotov and Sergey Ryazanskiy touched down on the snowy steppes of Kazakhstan at 11:24 p.m. EDT Monday (0324 March 11 GMT; 9:24 a.m. March 11 local time), about 3 1/2 hours after leaving the space station.

Temperatures hovered around 0 degrees Fahrenheit (minus 18 degrees Celsius) at the landing site, and strong winds whipped snow through the air.

"The crew will get a bit of a frigid welcome," a NASA commentator said as the Soyuz neared terra firma.

Because of the extreme conditions, recovery teams did not set up the standard medical tents for each crewmember.

Instead, Hopkins, Kotov and Ryazanskiy were to be taken immediately to a helicopter after being removed from the capsule.

The trio spent 166 days in orbit, and their mission was nearly extended by 24 hours.

Space station officials considered delaying the Soyuz' departure by a day because of bad weather on the ground in Kazakhstan but ultimately decided to go ahead with the original landing plan.

Hopkins, Kotov and Ryazanskiy launched toward the station on Sept. 26, initially joining the crew of the orbiting lab's Expedition 37.

In November, Expedition 37 transitioned to Expedition 38, which Kotov commanded.

Dale Gardner, Jetpack-Flying Astronaut Who Salvaged Satellites, Dies at 65

NASA astronaut Dale Gardner, who in 1984 achieved the world's first space salvage during his second shuttle mission, died on Wednesday (Feb. 19). He was 65.

Dale Gardner made history becoming the last of six astronauts to use the manned maneuvering unit (MMU) jetpack as he worked to return two malfunctioning satellites to Earth.

He died Wednesday from a sudden brain aneurysm. News of his passing was shared via social media on Thursday, with the Association of Space Explorers and the Kennedy Space Center Visitor Complex in Florida noting his death.

One of the so-called "Thirty-Five New Guys" (or "TFNG") who NASA recruited in 1978 to train for its then-new space shuttle, Gardner flew twice as a mission specialist aboard the orbiters Challenger and Discovery in August 1983 and November 1984, respectively.

Gardner's first spaceflight blazed a new path through the black sky as the first shuttle mission to launch and land at night.

The six-day STS-8 mission, which marked the third flight of space shuttle Challenger, deployed INSAT-1-B, a communications and weather satellite for India, while also testing the orbiter's robotic arm and, in a first, the space-to-ground communications using a new Tracking and Data Relay Satellite (TDRS).

Gardner's STS-8 crewmates included commander Richard Truly, who had piloted the shuttle's second test flight, pilot Dan Brandenstein, and fellow mission specialists William Thornton and Guy Bluford, the latter being the first African American in space.

It was only the second mission to fly with a crew of five, the largest contingent launched aboard a spacecraft at the time.

Gardner returned to space with the second flight of shuttle Discovery as a member of the STS-51A crew.

The eight-day mission first launched two Canadian communication satellites and then, in a move that made history, retrieved two malfunctioning satellites for their return to Earth.

The Wester 6 satellite for Western Union and Indonesian Palpa B2 satellite were deployed on a previous shuttle flight but had failed to reach their proper orbits due to failed motors.

As commander Frederick Hauck, pilot David Walker, and mission specialist Anna Fisher looked on from inside, Joe Allen and Gardner embarked on a pair of spacewalks to capture and secure the wayward satellites.

The twice-done feat, which required the spacewalkers to manually hold the satellites in the orbiter's payload bay, included Allen, and then Gardner donning the MMU jetpack, marking the last times to date that astronauts would fly untethered through open space.

On the successful completion of their salvage work and in a humorous nod to the malfunctioning satellites, Gardner revealed a hand-drawn "For Sale" sign, posing for a photo that would become one of the most iconic shots of the 30-year space shuttle program.

Landing Nov. 16, 1984, Gardner logged a two-mission total of 14 days and 52 minutes orbiting the Earth, including 12 hours and 14 minutes performing two spacewalks.

Dale Allan Gardner was born Nov. 8, 1948, in Fairmount, Minnesota, but was raised in Clinton, Iowa. Graduating in 1970 from the University of Illinois, Gardner entered active duty in the United States Navy and was assigned to flight officer training in Florida and Georgia.

Inside the ESA Cupola: NASA astronaut Chris Cassidy captures the Earth

Inside the Cupola, NASA astronaut Chris Cassidy, an Expedition 36 flight engineer, uses a 400mm lens on a digital still camera to photograph a target of opportunity on Earth some 250 miles below him and the International Space Station. 

Cassidy has been aboard the orbital outpost since late March and will continue his stay into September.
