Space Station Cosmonauts take a Walk in Space

Outside the International Space Station, Expedition 52 Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy conducted a spacewalk Aug. 17 to assess the condition of the exterior of the Russian segment of the complex and to install struts and handrails to facilitate future excursions. During the outing, Ryazanskiy manually deployed five small nanosatellites to collect data on a variety of scientific investigations. The spacewalk, which was the 202nd in support of space station assembly and maintenance, was the ninth in Yurchikhin’s career and the fourth for Ryazanskiy. Credit: NASA

Rare audio of indigenous languages saved by invention 100 years later3m57s

Rare audio of indigenous languages saved by invention 100 years later

Optical scan technology is helping researchers at the University of California (UC), Berkeley, preserve audio of 78 indigenous California languages, most of which were recorded more than a century ago. The recordings are on approximately 2,700 wax cylinders that are now barely audible due to issues such as mold. These are the only known sound recordings for several of the languages, and in many other cases, the recordings include unique speech practices and otherwise unknown stories and songs. With support from the National Science Foundation (NSF), linguist Andrew Garrett, digital librarian Erik Mitchell and anthropologist Ira Jacknis, all of UC Berkeley, are restoring these recordings. The researchers are using a non-invasive optical scanning technique that was developed by Lawrence Berkeley National Laboratory physicists Carl Haber and Earl Cornell. The collaboration with Haber and Cornell is enabling the NSF-funded research team to transfer all 100 hours of audio content from the wax cylinders and improve the recordings, finally making it possible to figure out which language is being spoken and what's being said. The rich Native American cultural collection will ultimately be accessible to indigenous communities as well as to the general public and scholars. The linguistic diversity of the world's estimated 7,000 languages is immense. Modern technologies like this one unlock the documentation to enable new community uses and scientific investigations. This research was co-funded by the National Endowment for the Humanities; grant number PD-230659-15. NSF support was provided by award #1500779, "Linguistic and ethnographic sound recordings from early twentieth-century California: Optical scanning, digitization, and access."

NASA's First 100 Days Of President Trump's Term

From a presidential call from the Oval Office with a record-breaking American Astronaut to announcing the discovery of Earth-sized planets outside our solar system, NASA's been busy during the first 100 days of President Trump’s term. Among the key moments was March 21 when President Trump signed the National Aeronautics and Space Administration Transition Authorization Act of 2017, the first comprehensive NASA authorization passed by Congress in more than six years. This bill helps ensure NASA remains at the forefront of exploration and discovery. NASA appreciates the strong support of the President, as well as our citizens in America and friends around the world. Credit: NASA

Time Lapse Of Tarantula Shedding Her Skin  In Only One Minute 58s

Time Lapse Of Tarantula Shedding Her Skin In Only One Minute

This is so fascinating! This is a short time lapse featuring a Brachypelma Smithi tarantula, named Pebbles, molting (shedding her skin). Pebbles is 11 years old and goes through this process at least once during a 1.5 year timeline. It was recorded over a 7-hour period, but with the time lapse, we can watch it all unfold in just one minute, incredible! This video makes the process look a lot shorter than it actually is. It is always so cool to see how nature works, especially when it's a tarantula shedding her skin! You don't see this very often! Brachypelma Smithi tarantulas are usually found around the central Pacific coast of Mexico and are also known as Mexican Red-Knee Tarantulas. They are usually found in dry areas with barely any vegetation, usually in deserts, or tropical forests. They live in burrows in rocky areas as the base of thorny vegetation like cacti. They are very large dark spiders and be quite intimidating if you aren't a spider lover. They usually won't cause any harm unless they are being threatened. In that case, they will show their fangs. Have you ever seen a tarantula before? Let us know in the comment section down below!

Water Rotation Experiment In Two Hemispheres 2m38s

Water Rotation Experiment In Two Hemispheres

We have heard the theory: water going down the drain spins in different directions depending on which hemisphere you're in. But what if you are at the Equator and then move a few meters towards the Southern hemisphere, then move back towards the Northern hemisphere and try the same thing? Can a few meters make a difference? Watch this and let us know your thoughts! Who would have thought that something like this could happen?! We have all heard of that theory before but most of us consider it just that, a theory or a myth. It seems that this theory really does have some merit as this video right here proves it! It seems that the reason for the results of this video is called the Coriolis force. It is caused by the earths rotations and ultimately effects the way the air around the water and the water itself is being pulled. In the Northern Hemisphere, it is pulled counter clockwise, while in the Southern Hemisphere it is pulled clockwise. Now do not be fooled, the Coriolis force is too weak to have any effect on any regular amount on water in your household such as draining a bath or flushing a toilet. It can only work depending on the way the drain is structured and that is why you seen the person putting the divider in the water before conducting the experiment. You can see the Coriolis force in action when you see a satellited image of a hurricane in either hemisphere! This force is responsible for the way that they spin! Please share this video with your family and friends as it will surely surprise them and is a clip that no one should miss!

Earth-like atmosphere unlikely to survive exoplanet's orbit 3m01s

Earth-like atmosphere unlikely to survive exoplanet's orbit

Scientists are studying our closest Earth-size exoplanet neighbor – Proxima b – to determine if it’s habitable. A recent computer simulation has provided good data on the question. Using Earth as a model – the simulation placed a planet with an Earth-like atmosphere into Proxima b’s orbit around its host star, Proxima Centauri. The simulation determined that the planet would likely lose its atmosphere from the effects of Proxima Centauri’s intense radiation and frequent flaring. Observations from our Chandra X-ray Observatory and other data were used for the simulation.

Nighttime Rocket Launch Creates Colorful Clouds in Space3m09s

Nighttime Rocket Launch Creates Colorful Clouds in Space

The early morning skies along the mid-Atlantic coast were lit up by luminescent clouds as NASA tested a new system to support science studies of the ionosphere and aurora, with a sounding rocket launch June 24 from the Wallops Flight Facility on the eastern shore of Virginia. During the flight of a two-stage Terrier-Improved Malemute sounding rocket, 10 canisters about the size of a soft drink can were deployed in the air, 6 to 12 miles away from the 670-pound main payload. The deployed canisters formed blue-green and red artificial clouds, or vapor tracers which allow scientists on the ground to visually track particle motions in space. The development of the multi-canister ampoule ejection system is also designed to allow scientists to gather information over a much larger area than previously allowed when deploying the tracers just from the main payload. The vapor tracers were expected to be visible from New York to North Carolina and westward to Charlottesville, Virginia – with the total flight time for the mission expected to be about 8 minutes.

SWEAT: Water Recycling 101

Water is a limited resource in space, making the urine and sweat of astronauts a valuable resource for recycling. Jennifer Pruitt, an engineer at #NASAMarshall, puts the "P" in purification to advance human exploration aboard the International Space Station​ and beyond. Scientists and engineers continue to improve existing methods and develop new, future recycling capabilities. Current success and results from ongoing investigations may help in the development of more reliable lightweight, portable waste processing equipment that can be used on Earth, including for emergency use or in areas with poor sanitation or unsafe drinking water.
