Watch What Happens When You Add Dye To A Floating Ball Of Water On The ISS

Another day and another incredible post from NASA. This video shows more astronauts messing around with liquids on board the International Space Station.

A few months ago, we sawTerry Virts releasing a ball of floating water and an antacid tablet into it. In this newly released video, we see astronauts inserting dye into floating balls of water. Simple, yet spectacularly elegant.

The RED Epic Dragon camera used for this footage is cable of shooting resolutions of up to 6,144 x 3,160 pixels and 300 frames per second. It was also the same camera used for The Hobbit trilogy and is commercially available if youve got a modest $57,805 (38,000) lying around. The cameras unbelievable quality means its able to capture even more information that can aid the astronauts with scientific investigations. Back home on Earth at theMarshall Space Flight Center in Huntsville, Alabama, NASA is looking into using the cameras for vehicleoperations such as docking and undocking.

NASA is also working on posting 4K videos from the ISSto itsYouTube channel every few weeks.

Make sure you watch the video in4K quality if youre using a screen capable of displaying itby clicking the settings cog in the bottom right of the player, its worth the download time.

Record Number Of People Apply To Be A NASA Astronaut

Mabye its the injection of private investment or Interstellar still echoing in our eyeballs, but space exploration seems to have recaptured the public’s imagination over the past few years. As proof of spaces ever-growing prestige, a record-breaking number of people have applied for NASAs 2017 astronaut class.

NASA opened applications in December 2015 and has since received the rsums of over 18,300 astronauthopefuls, smashing the previous record from1978s job posting, which received 8,000 applications. And this number istriple the amount who applied for thelast astronaut casting call in 2012.

Its not at all surprising to me that so many Americans from diverse backgrounds want to personally contribute to blazing the trail on our journey to Mars, Charles Bolden, NASA administrator and former astronaut, said in a statement.A few exceptionally talented men and women will become the astronauts chosen in this group who will once again launch to space from U.S. soil on American-made spacecraft.”

The next stage will involve trimming down those thousands by looking at their qualifications. From here, a select few will be invited for interviews at NASAs Johnson Space Center in Houston, Texas. Then, between eightand14 candidates will be selected for a two-year programthat trains them in spacecraft systems, spacewalking skills and Russian language lessons.

Its a pretty intense process, which NASA doesn’t expect to finish before mid-2017sodont get too disheartened if you haven’t heard from NASA yet.

Astronaut Will Compete in a Triathlon… in Space

Astronaut-will-compete-in-a-triathlon-in-space-25e5ca0ab7

As if holding the record for the longest spaceflight by a female astronaut wasn’t enough, NASA astronaut Sunita Williams is preparing to compete in a triathlon … in space.

Williams, who is stationed aboard the International Space Station, is planning to participate in the 26th annual Nautica Malibu Triathlon in September. But unlike the more than 5,000 athletes who will gather at Zuma Beach in California to swim, bike and run, Williams will compete while orbiting more than 240 miles above Earth. She left Earth July 17 for her second long-duration stay in the orbiting lab.

Williams will participate in the Nautica Malibu Triathlon in concert with CNN’s chief medical correspondent, Sanjay Gupta, for a CNN special. While Gupta sticks to a more Earthbound experience of swimming in the Pacific Ocean, bicycling and racing through the streets of Malibu, Williams will run, pedal, and engage in a series of bench presses that will serve as the microgravity equivalent of swimming.

As part of her triathlon training, Williams participated from space in the Aug. 12 Falmouth Road Race, an annual seven-mile race from Woods Hole in the town of Falmouth, Mass.

Now she has roughly a month to prepare for the triathlon, which requires competitors to swim half a mile in the ocean, bike 18 miles and run four miles.

Astronauts on long-duration missions at the orbiting outpost exercise roughly two hours each day to combat loss of bone and muscle density. The space station is equipped with a specially designed stationary bike, treadmill (complete with harnesses to keep participants from floating away) and a machine called the Advanced Resistive Exercise Device, or ARED, which acts as a weightlifting machine.

In recent interviews with CNN and WCIA radio in Illinois, Williams described the progress of her training in space, and how her body is adjusting to exercise in the microgravity environment.

“Microgravity is nice to your body,” Williams told WCIA. “You can float around, it feels good, but when you simulate gravity — when you’re on either the treadmill or the ARED — it sort of hurts. So it’s been a bit of an adjustment to get into the exercise.”

During her first two weeks in space, Williams spent time familiarizing herself with the machines, which are either new or have been upgraded since she was last at the space station in 2007.

“The first two weeks we’ve sort of used as a just-get-used-to-the-equipment, get used to the protocols that we’re doing,” Williams said at the time. “So I think we’re at that point that we’re finally adapted and ready to start building on it. So, just watch out, because now I’m ready to really start preparing for the triathlon.”

Williams told CNN that watching the 2012 Summer Olympic Games, which concluded this past weekend in London, helped provide motivation.

During the interview, Williams demonstrated how to use the space station’s bike, which has pedals but no seat. A nearby computer controls the resistance and speed of the bike, and also logs the astronauts’ heart rates as they ride.

“This is how I’m going to simulate the bike ride,” Williams explained. “For the hills, I can increase my resistance to match the route that you’re going to take, because I would assume that Malibu is not flat like Houston, right?”

For the swimming portion of the triathlon, Williams worked with experts in Houston to design a different exercise that she will be able to complete in orbit, said Kelly Humphries, a NASA spokesman at the Johnson Space Center in Houston.

The exercise was created by Mark Guilliams, who works as part of NASA’s astronaut strength, conditioning and rehabilitation group. It requires Williams to perform a type of modified bench press. That will serve as her swimming portion of the race, Humphries told SPACE.com.

Williams will use the station’s bike to pedal 18 miles and then will strap herself to the treadmill to complete the final four miles of running.

This is not the first time Williams has competed in orbit in a major athletic event. In 2007 Williams ran the Boston Marathon from the International Space Station, finishing with an official time of four hours, 23 minutes and 10 seconds.

There are currently six people living and working aboard the space station. In September Williams will assume command of the station’s Expedition 33 crew, becoming only the second woman to lead the orbiting outpost.

Astronaut Struggles To Adjust To Earth’s Gravity

ReelNASA is a NASA and space obsessed YouTube channel as their name suggests. In this new video that is apart of their Johnson Space Center satirical series, they poke fun at the common knowledge that astronauts must adjust to Earth’s gravity after returning from space.  

As they showcase Tom Marshburn struggling with his pen and cup, it becomes apparent that his needed adjustment is not what viewers had in mind.

NASA Stops Spacewalk After Water Leak Inside Astronaut’s Helmet

Luca-parmitano

NASA aborted a planned six-hour spacewalk by two astronauts outside the International Space Station Tuesday when a one of the spacewalkers reported “a lot of water” inside his spacesuit helmet, a potentially scary situation.

European Space Agency astronaut Luca Parmitano reported that helmet started filling with water, making it difficult for him to continue the spacewalk outside of the International Space Station. The spacewalk ended after one hour and 32 minutes. It was supposed to last six hours and 15 minutes.

“There is some in my eyes, and some in my nose,” Parmitano said. “It’s a lot of water.”

Parmitano reported the water in his spacesuit about one hour and nine minutes into the spacewalk. The cause of the water leak isn’t yet known, but the tasks scheduled for the spacewalk can be deferred until a later excursion, NASA officials said.

Cassidy and Parmitano began today’s spacewalk at 7:57 a.m. EDT. They wore NASA-issue spacesuits called Extravehicular Mobility Units, or EMUs. It ended at 9:29 a.m. EDT.

“[Mission Controllers on the ground] are taking the cautious path and ending the EVA early,” a NASA spokesman said during a broadcast on NASA TV.

Parmitano headed straight back to the U.S. Quest airlock on the International Space Station while Cassidy followed. Cassidy assured Parmitano repeatedly that he was close behind.

Once inside the airlock, the astronauts began repressurizing the chamber in order to return inside the station. At one point, Cassidy said it looked as if Parmitano could not hear any calls over his spacesuit radio.

“He looks fine,” Cassidy said. “He looks miserable, but okay.”

Today’s spacewalk was the second in eight days for Parmitano and Cassidy. The two astronauts planned to continue work that will prepare the station for the arrival of a new Russian multipurpose laboratory module slated to arrive later this year, and perform other maintenance tasks.

Private Astronaut Taxi Development Entering Final Phase

Dream-chaser-launch-ascent

Last week, NASA released a draft solicitation for the fourth and final development phase of its Commercial Crew Program — an initiative that has plans for a crewed space launch to the International Space Station from U.S. soil by late 2017.

The Commercial Crew Program is a NASA effort that subsidizes commercial development of systems to ferry astronauts to and from the space station. According to the draft solicitation, there would be two such flights per year, once NASA places its first task order for a crewed flight.

Before NASA releases the final solicitation this fall, the agency will host a pre-solicitation conference with industry at the Kennedy Space Center in Florida on Aug. 1 and 2, according to the draft. As expected, the contract will be a fixed-priced deal administered under the Federal Acquisition Regulations. So far, NASA has mostly relied on funded Space Act Agreements to subsidize development of commercially designed spacecraft.

While the competition is nominally free and open, it is generally believed that the companies with the best chance are those NASA is already funding as part of the third round of the Commercial Crew Program: Boeing Space Exploration Systems, Houston; Sierra Nevada Corp.’s Space Systems of Louisville, Colo.; and Space Exploration Technologies (SpaceX) of Hawthorne, Calif.

Boeing and SpaceX are working on capsules, while Sierra Nevada has a lifting-body design. All three spacecrafts could seat seven people. Boeing and Sierra Nevada plan to launch aboard United Launch Alliance’s Atlas 5 rocket, while SpaceX plans to use whatever iteration of its own Falcon 9 rocket is in operation in 2017.

If the schedule and funding hold, the planned demo flight — part of what NASA is calling the Commercial Crew Transportation Capability Contract — would be the first crewed orbital spaceflight launched from the U.S. since 2011, when the space shuttle program ended.

NASA has repeatedly said it needs more than $800 million a year — hundreds of millions more than Congress has ever given the program — to meet the 2017 date and keep more than one company involved with the program.
