This NASA documentary celebrates 50 years of extravehicular activity (EVA) or spacewalks that began with the first two EVAs conducted by Russian Alexey Leonov in March 1965 and American astronaut Edward White in June 1965 . The documentary features interviews with NASA Administrator and astronaut, Charles Bolden, NASA Deputy Administrator and spacesuit designer, Dava Newman, as well as other astronauts, engineers, technicians, managers and luminaries of spacewalk history. They share their personal stories and thoughts that cover the full EVA experience-- from the early spacewalking experiences, to spacesuit manufacturing, to modern day spacewalks aboard the International Space Station as well as what the future holds for humans working on a tether in space. "Suit Up," is narrated by actor and fan of space exploration Jon Cryer. Cryer recently traveled to Star City, NASA Headquarters and the Johnson Space Center to film an upcoming Travel Channel documentary series.

Since its inception in 1958, NASA has accomplished some pretty spectacular feats of science. Our country has landed humans on the Moon six times. We've successfully put laboratories onto the surface of Mars, and we've flown by every single planet in our solar system, including the recently promoted asteroid-turned-dwarf planet, Ceres.
Despite decades of scientific and technological achievements, some people still think that funding NASA is a waste of money. However, when you do the calculations, it turns out we are actually getting a great value from this government-run agency.

"In science fact, though, there's greater concern that Earth-dwellers-specifically bacteria and microorganisms-could arrive at extraterrestrial destinations. As NASA sends rovers to Mars, plans a trip to Jupiter's icy moon Europa, and looks for an ocean on Saturn's moon Enceladus, the hope is to find life-forms on those interstellar bodies. To ensure that doesn't include forms that originated on Earth-and that the new environment isn't compromised the way Earth ecosystems can be by invasive species or infectious diseases-NASA is now thoroughly cleaning its space-bound vessels."

After 30 years of missions, NASA finally retired its aging space fleet in 2011. Since then, they've been dependent on Russian capsules to take Americans to and from the ISS, at the prohibitive cost of about $70 billion per astronaut. But recently signed deals with Boeing and SpaceX are supposed to fill the gap, using commercial spacecraft to transport station personnel. Much of the maintenance shown in Wilmore and Virt's video is in preparation for these commercial flights, which are meant to commence in 2017. The footage was intended to give future astronauts an idea of what working on the station would be like when they arrived. Here is a short edit of the clips from the AP:  

On September 27th, 2015 there will be a very rare event in the night sky - a supermoon lunar eclipse. Watch this animated feature to learn more.

Find out why NASA astronaut Dr. Mae Jemison wanted to go into space in this profile from NOVA's The Secret Life of Scientists and Engineers.

A physician, a chemical engineer, a teacher, a dancer, and the first African American woman astronaut to go to space, Dr. Jemison launched into orbit on September 12, 1992 as a STS-47 Mission Specialist for Space Shuttle Endeavor. During the eight day mission, she and the STS-47 crew conducted 44 life science and materials processing experiments.

In a sneak peek of a possible future mission to Saturn's moon Titan, NASA has showcased their vision of a robotic submersible that could explore the moon's vast lakes of liquid methane and ethane.

VIDEO: Can a Moon be Older Than its Planet?

Studying Titan is thought to be looking back in time at an embryonic Earth, only a lot colder. Titan is the only moon in the solar system to have a significant atmosphere and this atmosphere is known to possess its own methane cycle, like Earth's water cycle. Methane exists in a liquid state, raining down on a landscape laced with hydrocarbons, forming rivers, valleys and seas.

As soon as NASA announced finding evidence of liquid water on Mars last month, speculation erupted that scientists may be able to answer the age-old question: Is there life on Mars?

Technically, we already know the answer.

"The answer is, 'Yes,' and it's probably our own life," says David J. Smith, a scientist at NASA's Ames Research Center in Mountain View.

Here on Earth, bacteria cover every surface we touch. And despite efforts to keep spacecraft as clean as possible, bacteria have likely hitchhiked all the way to Mars on NASA missions. Bacterial contamination was detected on the rovers that have driven across the red Martian desert.

When you picture a rocket, you might imagine a giant ship carrying lots of fuel, people and supplies. But what if the next wave of spacecraft were small enough to fit into our pockets? Dhonam Pemba details the future of microspacecraft, and how scientists at NASA are hoping to use micropropulsion to launch these tiny vessels outside of Earth's orbit.

A new documentary from NASA tells of the difficulties of sending an astronaut into cold, deadly space, plus how far we've come since Gemini 4. Since the days of the first "extra-vehicular activities", spacewalks have allowed mankind to walk on the Moon, build the International Space Station, and save the Hubble telescope. And we're not done yet. Future spacewalks will take us even farther-to asteroids orbiting the Moon, and eventually, Mars. Check out the documentary to learn more:

"As a life support engineer at NASA Ames Research Center, it's Michael Flynn's job to keep astronauts alive in space, making sure they have the basic necessities like clean water to survive. But launching clean water into space is cost-prohibitive, so for years, Flynn and his team have been working on new ways to recycle waste water into safe, drinking water. SmartPlanet visits Flynn's lab and looks at how he's doing it through a process known as "forward osmosis.""

NASA Sci Files segment explaining the phases of the moon and how they are created.

The public is responding in novel ways to share its own enthusiasm. There's the annual Yuri's Night space party April 12, celebrating Cosmonaut Yuri Gagarin's first flight into space April 12, 1961, and promoting space exploration. The Desert Wizards of Mars, a global group of scientists, designers, and builders, bring space education to Burning Man. The Facebook community Space Hipsters disseminate news about space issues, enthusiast meet-ups, and related personal anecdotes among its roughly 3000 members. (NASA's Jacobs drops in on occasion to say hi "and show that we're paying attention.")

National Geographic Channel is taking viewers around the world-literally-in this spectacular two-hour television event broadcasting LIVE from the International Space Station (ISS) and Mission Control in Houston, Texas. Made in collaboration with NASA, we'll go into orbit with astronauts Rick Mastracchio and Koichi Wakata as they fly at 17,500 mph nearly 250 miles above the earth's surface on the International Space Station, while astronaut Mike Massimino joins host Soledad O'Brien on the ground at Mission Control in Houston. From space, Mastracchio and Wakata will give viewers a fully guided tour, showing us how they live for months in microgravity. They'll conduct never-before-broadcast experiments that demonstrate the real-world value of the science conducted on the floating laboratory. Plus get ready for stunning shots of Earth, from sunset and sunrise, to city lights and green aurora, to lightning storms and shooting stars. You've never seen our planet like this before.

On March 28, NASA astronaut Scott Kelly began a historic year in Space. Time follows Kelly and his twin brother, Mark, as they work the test the boundaries of long-term space travel.

Just a week after NASA scientists announced their certainty of finding alien life within the next 20 years, a team of scientists say they've found no obvious signs of advanced extraterrestrial life after searching 100,000 galaxies.

Mission Overview: Why Go to Pluto ? Planetary exploration is a historic endeavor and a major focus of NASA. New Horizons is designed to help us understand worlds at the edge of our solar system by making the first reconnaissance of Pluto and Charon - a "double planet" and the last planet in our solar system to be visited by spacecraft. Then, as part of an extended mission, New Horizons would visit one or more objects in the Kuiper Belt region beyond Neptune.

NASA is studying Ceres -- a protoplanet. We are interested in Ceres simply because it is FULL of water. Scientists think that bodies like Ceres could be the source of water on earth. Collisions of two or three of these bodies could have brought all of our water.
