The High Definition Earth Viewing (HDEV) experiment places four commercially available HD cameras on the exterior of the space station and uses them to stream live video of Earth for viewing online. The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. The cameras are enclosed in a temperature specific housing and are exposed to the harsh radiation of space. Analysis of the effect of space on the video quality, over the time HDEV is operational, may help engineers decide which cameras are the best types to use on future missions.
According to scientists cosmic rays from beyond our solar system constantly pummel Earth’s moon, fundamentally changing the chemistry and color of the lunar ice and dirt. New measurements of the strength of this space radiation from NASA’s Lunar Reconnaissance Orbiter show that these cosmic rays can cause significant chemical alteration on the surface of the moon. The measurements also help scientists test theoretical models of the moon’s radiation environment.
The globular cluster, called Messier 9, shines in this new photo from the Hubble Space Telescope.The cluster Messier 9 contains hordes of stars swarming in a spherical cloud about 25,000 light-years from Earth. The object is too faint to be seen with the naked eye, and when it was discovered by French astronomer Charles Messier in 1764, the scientist could only resolve it as a faint smudge that he classified as a nebula. Hubble Space Telescope released a new picture of Messier 9 on March 16.
According to Nasa the launch of the first commercially built space capsule to the International Space Station will occur at the end of April. California-based Space Exploration Technologies (SpaceX) is now aiming to launch its unmanned Dragon spacecraft on a demonstration flight to the orbiting outpost at 12:22 p.m. EDT (1622 GMT) on April 30. This test flight was originally slated to occur in early February, but the mission was delayed to allow extra time to test the spacecraft and its software.
Observations of Solar Dynamics Observatory (SDO) indicate that the powerful explosive processes in the Sun, solar flares, bring to the boundary of Earth’s atmosphere more than three times more energy than previously thought.
Russia has announced plans to create a unique space hotel in orbit, in which can be placed seven people in four cabins.
Asteroid 2010 SO16, discovered earlier telescope WISE, moves almost exactly on the Earth’s orbit and may be a “brother” of the Earth – one of a group of protoplanetary celestial bodies, from which it emerged, according to astronomers from the Northern Ireland Observatory Armag. Most asteroids near Earth (NEA), have very elongated orbits, SO16 but has a nearly circular orbit, and therefore can not converge to any other planet except Earth.Astronomers have decided to establish how stable the orbit of this asteroid, and how long it takes her.
