In microgravity, however, the small chemical reaction is a spectacle, as evidenced by new footage from the International Space Station: The newly released video is so mesmerizing thanks in part to the Epic Dragon, the advanced 4K camera used to shoot it. First delivered to the ISS earlier this year, Epic Dragon is capable of shooting with six times more detail than other cameras aboard the space station. "The cameras are being evaluated for capturing science data and vehicle operations," the agency explains in a news release. "The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. " Although you'll need a special monitor to get the full 4K experience, the high-definition footage still looks pretty remarkable on a standard screen.

NASA: What We Have To Do To Get to Mars

Updated details of the space agency’s Mars strategy were contained in a 36-page document released to the public ahead of upcoming talks with Congress about budgets for space exploration and a major international meeting of the space industry to be held in Jerusalem next week. The United States is “closer to sending American astronauts to Mars than at any point in our history,” said NASA administrator Charles Bolden. Photos: Real NASA Space Tech in ‘The Martian’ “In the coming weeks, I look forward to continuing to discuss the details of our plan with members of Congress, as well as our commercial and our international partners, many of whom will be attending the International Astronautical Congress next week,” he said in a statement.

Many of the photos have been seen before in some form or another, but this is the first time that the unprocessed, high-resolution version of NASA's most iconic lunar mission photography has been presented in one exhaustive collection. Kipp Teague, a Virginia-based NASA enthusiast who spearheaded the project, originally started curating NASA's content in 1999, when he launched the Project Apollo Archive. The website serves "as an online reference source and repository of digital images pertaining to the historic manned lunar landing program. " Teague's website, however, featured NASA-processed versions of the mission photographs, which were color-corrected and adjusted for brightness.

For years, a team of NASA scientists had pondered over the enigmatic dark streaks lining the inner and outer faces of craters on the Martian surface, shown below.

Photos of water on Mars

But no longer. NASA announced the answer to the conundrum Monday: The streaks are evidence of flowing water. NASA/JPL-Caltech/Univ. of Arizona Most mysterious about these streaks — which can be as long as a football field — was that they appeared to change in size over time, growing longer during Mars' warm summer months and shrinking during colder seasons: If these photos were taken on Earth, the immediate conclusion would be flowing water. All that changed Monday when the NASA team announced that these dark, mysterious features were, indeed, flowing water. There are many pieces that had to fit together to finally conclude, beyond a doubt, that this was water and not a bizarre pattern from Martian weather.

The craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments will characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail. The spacecraft's most prominent design feature is a nearly 7-foot (2.1-meter) dish antenna, through which it will communicate with Earth from as far as 4.7 billion miles (7.5 billion kilometers) away.
