Lee Rannals for redOrbit.com - Your Universe Online Virgin Galactic hasn't even taken a tourist to space yet, but the company is already expanding its means by partnering with Planetary Resources to launch tools into space. Planetary Resources will be relying on the transportation of Virgin Galactic to launch a series of spacecraft, including the Arkyd-100 low-Earth orbit (LEO) space telescopes. The company's goal is to eventually mine asteroids, but first has to take a series of...

Privately-Funded Deep Space Mission Planned
2012-06-30 05:59:00

Lee Rannals for redOrbit.com - Your Universe Online Former astronauts are making plans to build and launch their own space telescope to track down dangerous asteroids. The B612 Foundation, which is made up of former NASA astronauts and U.S. scientists, said it plans to launch the first privately funded deep space mission. The company said that its Sentinel mission would see that a space telescope be placed in orbit around the sun. Ed Lu, a former NASA astronaut who flew aboard...

Lee Rannals for redOrbit.com An asteroid about the size of a football stadium may slightly have a chance of impacting Earth in 2040, but new estimates show it's hardly a threat. The space rock, measuring about 460-feet in size, has a likelihood of missing Earth greater than 99 percent, according to the recent findings by scientists at a May 29 workshop at NASA's Goddard Space Flight Center. "While there is general consensus there is only a very small chance that we could be dealing...

Team Setting Up Strategy For Hazardous NEOs
2012-06-05 11:35:46

Lee Rannals for redOrbit.com Scientists have gathered with other experts to create a strategy for potentially hazardous Near earth Objects (NEOs). Nearly 40 scientists, reporters, risk communications specialists, and Secure World Foundation staff participated in a meeting in November last year to come up with a strategy for dealing with hazardous NEOs. The report created by the team will be presented at the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and its...

Scientist Guesses Asteroid's Weight, Millions Of Miles Away
2012-05-25 11:18:04

Lee Rannals for RedOrbit.com A NASA scientist would be a shoe-in at any state or county fair if hosting the "guess your weight" game. Steve Chesley of JPL's Near-Earth Object Program Office has accurately determined the mass of an asteroid from millions of miles away. Chesley used data from the Goldstone Solar System Radar in the California desert, along with the orbiting Spitzer Space Telescope and the Arecibo Observatory in Puerto Rico, to make his findings. He said he first...

US Not Losing Its Foothold In Earth Observing Satellites, Only Shifting Power
2012-05-22 12:23:35

Lee Rannals for RedOrbit.com Speculations are emerging that the U.S. may be losing its foothold in Earth observing satellites technology, which could inevitably lead to a science community that is behind the times. However, the one thing these reports fail to account for is the up-and-coming commercialized space industry. Reports from several news agencies point to a new study by the American Meteorological Society Policy Program, as well as expert sources, to show how the economic...

NASA Keeping An Eye Out For Dangerous Asteroids
2012-05-17 11:24:34

NASA has just received observations from its WISE (or Wide-field Infrared Survey Explorer) mission, giving them the best assessment thus far of how many PHAs (potentially hazardous asteroids) are floating around in our solar system. Now, the team at NASA can count these PHAs, discover their origins and predict what kind of harm they may pose to Earth. According to a report from NASA´s Jet Propulsion Laboratory in Pasadena, these PHAs are a subset of a larger group of near-Earth...

ESA Teaming Up With Amateur Astronomers To Spot Near Earth Objects
2012-05-14 11:01:47

Lee Rannals for RedOrbit.com The European Space Agency (ESA) is reaching out to amateur astronomers, asking for their help in discovering potentially dangerous space rocks. ESA's Space Situational Awareness (SSA) program helps keep up with space hazards, with everything from space weather to debris objects in Earth orbit. The program also keeps up with "Near Earth objects," or NEOs, which are asteroids that pass close enough to our planet to cause concern. NEOs are hard to survey...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
