Having seen Canada with his own eyes — all of it, from space — Chris Hadfield is emboldened with a holistic concept of our nation. “I’ve had a chance to look at it from a perspective most people haven’t,” says the retired Canadian Space Agency astronaut over the phone, “and I don’t mean that facetiously. “I’ve been across it thousands of times in spaceships, seen the whole thing coast-to-coast in eight minutes. But I’ve also, as an astronaut, had a chance to live in different provinces, visit so many communities, speak in so many schools — and maybe think about it in a little different way.” Mining this perspective, Canada’s first space commander and the first of us to walk in space is travelling the nation for Chris Hadfield’s Canada 150 Tour, offering his perspective in story and song — including the cover of David Bowie’s Space Oddity he famously sung while orbiting on the International Space Station.

International Space Station (ISS) crew member Scott Kelly of the U.S. shows a victory sign after landing near the town of Dzhezkazgan, Kazakhstan, on Wednesday, March 2, 2016. (Krill Kudryavtsev/AP) After 340 consecutive days in space, Commander Scott Kelly’s return to normal activity on Earth will be gradual. Life in space takes a toll on the human body, changing a person’s eyesight, affecting memory and motor control. A major part of Kelly’s mission is to help NASA get a better understanding of those changes so that it may find out what future astronauts might experience on the long journey to Mars.

Kazakh cosmonaut to replace Brightman on space station trip. Sen—A 43-year-old Kazakh cosmonaut, Aidyn Aimbetov, will replace British singer Sarah Brightman on a trip to the International Space Station (ISS) in September, Russian officials announced Monday. Aimbetov will join a three-member crew of the Soyuz TMA-18M spacecraft, following Brightman's withdrawal from training for the flight. The team also includes the Russian commander Sergei Volkov and Danish astronaut Andreas Mogensen, representing the European Space Agency (ESA). Soyuz TMA-18M is currently scheduled for launch on Sept. 1, 2015. After arrival at the station, Sergei Volkov will replace Gennady Padalka who will complete a more than five-month stay aboard the ISS. One Soyuz always stays docked at the station to provide evacuation for a three-member crew, and two lifeboats are parked at the outpost when a full six-person crew is onboard. The former Soviet cosmonat Talgat Musabaev, who became a Kazakh citizen, flew three missions onboard the Russian spacecraft in 1994, 1998 and 2001.

Sixteen months after a fatal test flight destroyed its first spaceship, Virgin Galactic on Friday is unveiling a second vehicle intended to fly paying passengers into suborbital space.

From the outside, the new spaceship resembles the fleet leader, which broke apart over Mojave, California, on Oct. 31, 2014, during its fourth powered test flight. Co-pilot Michael Alsbury, who worked for SpaceShipTwo designer and manufacturer Scaled Composites, was killed in the accident. Pilot Pete Siebold managed to parachute to safety. ANALYSIS: Virgin Galactic SpaceShipTwo Crash: What We Know Virgin Galactic had already had taken over manufacturing and testing of future ships, a plan that was accelerated after the accident, Will Pomerantz, vice president of special projects, told Discovery News.

The new spaceship includes dozens of upgrades, some planned before the accident to ease commercial operations and reduce costs, some added as a result of the accident investigation. Weather. In early spring in the Northern Hemisphere, what might appear as city lights on the horizon is actually a hard-to-spot astronomical phenomenon. This glow is known as zodiacal light, and we're nearing the season for it. Zodiacal light (named for the Zodiac, or pathway of the sun across the sky) appears as an unusual triangle or pyramid, sparkling just above the horizon shortly after sunset. At first glance, the light can resemble the glow other sources, such as light pollution or the stars, can cast.

But it's actually sunlight reflecting on "interplanetary dust particles” from comets, asteroids and even the creation of the planets in our solar system, according to NASA resources. These “dust grains,” as names them, emanate from the sun in a flat disc, the same space the planets of the solar system occupy. But too often factors from Earth distort our view of these interplanetary particles, and the "counterglow" from the sun known as gegenschein. With that, happy hunting. ORBCOMM-2 Full Launch Webcast.

NASA has released spectacular footage of the “dark side” of the moon – fully illuminated – as the Earth’s natural satellite was moving across the sunlit side of our planet. The unique shots were captured by the Deep Space Climate Observatory. Taken by the Earth Polychromatic Imaging Camera (EPIC), the images show a unique view of our planet and the moon from one million miles away. The capture of this rare spectacle was made possible due to the orbiting trajectory of the DSCOVR satellite that is positioned between the Sun and the Earth, giving it the capability to see the far side of the moon. “It is surprising how much brighter Earth is than the moon,” said Adam Szabo, DSCOVR project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“Our planet is a truly brilliant object in dark space compared to the lunar surface.” The series of images taken on July 16 were compiled into GIF animation that depicts the moon flying over the North America and the Pacific Ocean. SpaceX plan vs reality: Satellite launched, ocean platform landing botched. The private spaceflight company SpaceX has launched a reusable rocket that is supposed to deliver a NASA ocean-monitoring satellite into low-Earth orbit. However, the audacious plan to land the rocket on a platform at sea in the Pacific Ocean did not go as smoothly as planned. SpaceX failed to land the Falcon 9 rocket on the platform, despite the first stages of the launch being successful, the company officials said. The touch-down must have been “hard,” since the rocket’s landing leg broke. The Space X Flacon 9 rocket took off with the Jason-3 satellite from California's Vandenberg Air Force Base at 10:42 a.m.

PST (1842 GMT), as planned. Jason-3 will continue the research started in 1992 by measuring the topography of the ocean floor which could help forecast weather patterns, predict hurricane intensity and basically monitor Earth’s climate. It took an hour to deploy the satellite before it finally reached low-Earth orbit. Twitter. Twitter. ?. Scott Kelly (@StationCDRKelly) | Twitter.

Global Ocean Beneath Enceladus’ Surface Titan Observed Outside of Saturnian Magnetosphere Density of A Ring Particles May Indicate Recent Origins Titan Southern Polar Ice Cloud • Scientists have detected a monstrous new cloud of frozen compounds in Titan’s low- to mid-stratosphere – a stable atmospheric region above the troposphere, or active weather layer. • A large cloud, first seen in 2012 at higher altitudes, turned out to be just the tip of the iceberg. Curtain Vents on Enceladus? Study: Lunar Colonization Could be Surprisingly Cheap — But There’s a Catch. NASA could dramatically cut the cost of returning humans to the moon if it is willing to mine and sell the moon's natural resources, according to a study commissioned by the agency.

The Space Frontier Foundation-penned study encourages NASA to mine the moon's hydrogen for the "commercial production of cryogenic propellant". The report estimates that there are 10 billion cubic meters of water on the moon's poles -- equivalent to Utah's Great Salt Lake. The mining operation could potentially reduce the cost of sending humans to the moon by 90%. First, however, NASA must send robotic scouts to confirm that the polar water is even harvestable.

"This will be a complex operation requiring a period of growth, trial and error, failure, repair, and maintenance as the process matures in operations and procedures," the report concedes.

A mysterious ball of light soared over the Las Vegas skyline Tuesday evening, and before you ask -- no, it wasn't the same object the NORAD will be tracking later this week. In a Facebook post, the United States Strategic Command explains that the flash of light was actually a Russian SL-4 rocket body burning up as it re-entered Earth's atmosphere. The flaming junk, which first appeared around 6:00 p.m. local time, was visible across parts of Nevada and California. Dazzled stargazers throughout the region took to social media to share their accounts of the unexpected show: There are more than 21,000 pieces of space debris larger than 4 inches across currently orbiting Earth. As part of its initiative, the USSC maintains a comprehensive database of 16,000 of these "on-orbit cataloged objects," tracking their movement until they burn up.
