Slooh To Broadcast Moon's Asteroid Collision
2013-05-20 14:27:46

Lee Rannals for redOrbit.com - Your Universe Online An organization aimed at bringing celestial event programming to everyone with a computer, iPhone or iPad is planning to broadcast the fiery explosion that took place on the moon just a few months ago. On March 17 NASA astronomers witnessed how the Moon was rocked by a violent impact from an 88-pound asteroid, creating a flash nearly 10 times as bright as anything the space agency had seen before. Now Slooh says it wants to bring the...

Asteroid Exploration Field Tests Performed In The Mojave Desert
2013-05-18 05:39:53

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The potential of a human mission to Mars has captured the imagination of many recently. However, before astronauts set foot on the Red Planet, NASA first plans to visit Near-Earth asteroids and potentially to the moons of Mars. With this vision in mind, a team of researchers from the SETI Institute, the Mars Institute, NASA Ames Research Center, and the space robotics company Honeybee Robotics successfully completed a...

QE2 Asteroid Hurtles Past Earth On May 31
2013-05-30 13:20:39

Brett Smith and Lee Rannals for redOrbit.com - Your Universe Online [ Update: May 30, 2013 - Asteroid 1998 QE2 Has A Moon ] Radar data taken on Wednesday has revealed that asteroid 1998 QE2 has an orbiting moon. NASA said that about 16 percent of asteroids are binary or triple systems. The 1.7 mile wide asteroid will be passing by Earth at a safe distance of about 3.6 million miles on Friday. [ Watch the Video: Radar Reveals Asteroid 1998 QE2 has a Moon ] [ Update: May 30, 2013...

Scientists Gathering To Discuss NEO Threat Mitigation
2013-05-08 18:57:57

Lee Rannals for redOrbit.com — Your Universe Online Scientists around the world are meeting in Spain this week to talk about the threat asteroids pose to Earth. Deimos Space, an industrial partner working for the European Space Agency's (ESA) Space Situational Awareness (SSA) program, has invited researchers from universities, research institutes, national space agencies and space industry professionals to discuss Near-Earth Object (NEO) threat mitigation and effects. NEOs are...

Monitoring Elusive Collisions In Space
2013-04-24 06:09:40

April Flowers for redOrbit.com - Your Universe Online Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts. New research from the University of California, Los Angeles, has devised a method to monitor these types of collisions in interplanetary space. The team used a new method to determine the mass of...

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...

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...
