2012-10-13 05:05:52

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) reports that it has rediscovered an asteroid that was once lost through the agency's space hazards program. Potentially Hazardous Asteroid 2008SE85 was first discovered back in September 2008 by the Catalina Sky Survey, and was observed by a few observatories the following month. However, no one since then has observed the object, and predictions for its current position had become so inaccurate that...

Lee Rannals for redOrbit.com — Your Universe Online In relative terms, the Earth is about to escape another asteroid impact on Thursday by the hair on its chin. Although it's not like the 14-story sized asteroid is going to be nearing so close to Earth that you will be getting a prime view of in it your backyard, it will be about 7.5 times the Moon's distance from our planet. The asteroid, which is between 625 and 1,400 feet across, is close enough to Earth to be classified a...

Asteroid Needs A Name!

Watch the Video: NASA Announces Asteroid Naming Contest Lee Rannals for redOrbit.com - Your Universe Online NASA is opening up an opportunity for students to help name an asteroid the space agency will be gathering samples from and returning back to Earth. The Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) mission is scheduled to launch in 2016. During the mission, a spacecraft will land on the near-earth asteroid currently called 1999...

Privately-Funded Deep Space Mission Planned

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...

City-Block Sized Asteroid Whizzing By Earth Tonight
2012-06-14 13:52:39

Lee Rannals for redOrbit.com A huge asteroid the size of a city block will be skimming by Earth on Thursday night at 8:00 eastern time. The giant space rock is about 1,650-feet wide and is big enough to qualify as a potentially hazardous asteroid.  However, experts stress there is no chance of a collision, and it will be passing Earth at a safe 3 million miles away. Astronomers in Australia discovered the asteroid 2012 LZ1 on Sunday night, and found that the object is going to...

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...

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...

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...
