Human Asteroid Exploration: The Long And Storied Path
2013-04-17 10:43:01

NASA Within NASA´s new FY2014 budget proposal lies a project known as the Asteroid Retrieval and Utilization Mission. This project would be the first to capture a small near-Earth asteroid and safely redirect it to a lunar orbit so that astronauts can visit and explore it. Such a mission would expand scientific knowledge of the origins of both humanity and the universe. The goal of asteroid retrieval is not a new endeavor for NASA. In fact, the idea dates to the earliest days of...

Targeting An Asteroid
2013-04-17 10:28:38

NASA's Jet Propulsion Laboratory Like many of his colleagues at NASA's Jet Propulsion Laboratory, Pasadena, Calif., Shyam Bhaskaran is working a lot with asteroids these days. And also like many of his colleagues, the deep space navigator devotes a great deal of time to crafting, and contemplating, computer-generated 3-D models of these intriguing nomads of the solar system. But while many of his coworkers are calculating asteroids' past, present and future locations in the cosmos,...

Asteroid Tracking Sensor Passes Key Test
2013-04-16 07:07:54

April Flowers for redOrbit.com - Your Universe Online A critical design test for an infrared sensor that could improve NASA's future ability to detect and track asteroids and comets has been passed. The Near Earth Object Camera's (NEOCam) performance in an environment that mimicked the temperatures and pressures of deep space were assessed by the test. NEOCam will be the key instrument for a proposed new asteroid-hunting space-based telescope for which design and capability details have...

President Barack Obama's NASA Budget Proposal Welcomed By UA Asteroid Experts
2013-04-11 08:10:17

University of Arizona Scientists at the University of Arizona welcome President Barack Obama's NASA budget proposal, rolled out today, and specifically its focus on gaining a better understanding of asteroids that could potentially harm Earth. The UA has a unique depth of capabilities and expertise that can help inform such missions and ensure their success. The UA is operating the most prolific ground-based system for identifying near-Earth asteroids, and it is tasked by NASA with...

NASA Warns Lawmakers More Funding Needed To Protect Earth From Doomsday Asteroids
2013-03-20 09:23:02

Lawrence LeBlond for redOrbit.com - Your Universe Online The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.” That is unless, of course, the government can do more now to ensure...

Asteroid 2013 ET Captured By Deep Space Network
2013-03-20 08:50:01

April Flowers for redOrbit.com - Your Universe Online On March 10, 2013, NASA scientists obtained a sequence of radar images of asteroid 2013 ET using the 230-foot Deep Space Network antenna at Goldstone, California. At the time the images were captured, the asteroid was about 693,000 miles from Earth, or approximately 2.9 lunar distances. The asteroid is irregularly shaped and at least 130 feet wide according to the radar imagery. The scientific team, led by Marina Brozovic and Lance...

Passing Asteroid Will Be Broadcast Live By SLOOH Today
2013-03-09 12:02:37

Lee Rannals for redOrbit.com — Your Universe Online An asteroid about the size of a city block will be making its way past Earth later today, and Slooh plans on giving the world access to its tools to view the near-Earth object (NEO). Slooh, a leader in live, celestial event programming, said in a statement earlier this week that it will be broadcasting the asteroid 2013 ET on Saturday (Mar 9) as the it passes by Earth at about 2.5 times the Moon's distance from us. 2013 ET was...

The Hunt For Near-Earth Asteroids Heats Up After 2012 EC Passes Earth
2013-03-05 06:16:21

Lawrence LeBlond for redOrbit.com - Your Universe Online An asteroid that was only discovered Saturday (Mar. 2) has made a run by Earth in the early hours of March 5, some 250,000 miles away. While the asteroid is being associated with last month´s Russian meteor in respect to its mass, the two bodies are not linked in any other way. The asteroid, 2012 EC, was detected by Arizona´s Mt. Lemmon Observatory and astronomers calculated its trajectory, confirming the object would...

Asteroid Mission Targets Didymos In 2022
2013-02-23 05:53:38

redOrbit Staff & Wire Reports - Your Universe Online In the wake of the recent meteor explosion above Russia, the European Space Agency (ESA) has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA). The AIDA mission, which is a joint project headed up by European and American astronomers, will attempt to intercept asteroid Didymos, which the ESA says is a “binary,” featuring two asteroids — one approximately 800...

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...
