How the ISS Plans on Getting Rid of Space Debris—Plans to Vaporize Comets in Space

Medicine & Technology Fans of shoot-em-up sci fi everywhere will be thrilled with the latest proposal for freeing the International Space Station (ISS) from the need to repeatedly alter its trajectory to avoid crashing into space junk. Researchers from the Riken Computational Astrophysics Laboratory of Japan want to use a laser system to zap dangerous space debris on a collision course with the ISS.

A New Vehicle in the Works to Investigate the Hellish Atmosphere of Venus

While much attention has been paid to Martian exploration in recent years, there remains a dedicated cadre of scientists focused on Earth's twin, Venus. And in a recent press release from Northrup Grumman, plans for a new vehicle were unveiled that just might provide a bird's eye view of this hot and hostile planet.

Russia Restarts Progress Spacecraft on ISS After Failed First Attempt

The problems for Russia's space agency seem to continue. The Russian Space Agency said that after a failed first attempt to start the engines of the Progress spacecraft on the International Space Station, they managed to get them started on the second attempt to correct the orbit of the ISS.

SpaceX Aggressive Schedule Leading to Manned Space Flights

SpaceX continues to push the envelope on its march to sending manned missions into space. In the coming months, SpaceX will continue its high visibility tests of the Dragon spaceship in an effort to one day send human into space.

SpaceX Earns Certification to Launch NASA Science Missions

It's official. NASA has formally certified SpaceX's Falcon 9 rocket to launch all but the agency's most costly robotic science missions. The first mission for SpaceX will be the launch of a United States and France oceanography satellite that is scheduled for liftoff from California in July.
CubeSat

NASA Searches for Small Satellite Launchers

Students and scientists continue to pack increasingly innovative missions into tiny satellites known as CubeSats, but getting them to space proves both difficult and expensive. A NASA program based at Kennedy Space Center hopes to help introduce a new class of rockets designed specifically for very small satellites, or even bunches of them.

Rare Quasar Quartet is the First of Its Kind

Imagine winning the Powerball jackpot-more than once. You may have a sense of how a team of astronomers feels after their discovery of a set of four quasars at the visible universe's edge. These brilliant beacons of light are typically spread far apart, but this quartet exists shoved together in only 650,000 light-years of space-equivalent to around a quarter of the distance between our closest big neighbor galaxy Andromeda and the Milky Way.

NASA Probe Searches Pluto for New Moons and Rings

NASA’s New Horizons space probe is set to make the history books when it flies past Pluto on July 14. Currently, the probe looking closely at the little dwarf planet as it looks for anything that could cause problems for the craft during the final months of its historic mission.

NASA Scientist Says Space Mining Needs Oversight

While prospecting and mining on the moon or on asteroids is probably a couple of decades away from becoming reality, according to a NASA scientist speaking at a symposium on planetary and terrestrial mining, oversight will be needed by a body much like the United Nations.
Mars

Humans May Not Have to Carry Oxygen to Mars

NASA is already in the planning stages for a future trip to Mars, and one of the hurdles they must jump is how humans will breath on the Red Planet. However, instead of carrying huge oxygen tanks, future human missions may actually utilize methods to actually produce the life giving gas on the planet itself.
