Computing Asteroid Paths For Future Exploratory, Redirect Missions
2014-07-01 12:19:30

Gerard LeBlond for redorbit.com - Your Universe Online Asteroids are chunks of debris left over from the solar system’s formation. They are a substantial interest to scientists, having possible resources embedded within them. Water, along with other resources found on these asteroids would be a benefit to astronauts traveling into deep space with missions to Mars and even deeper in our solar system. Currently, NASA is developing methods needed for a 2030s mission to Mars. In the...

Citizen Scientists Can Now Help Discover NEAs Using Asteroid Zoo
2014-06-25 09:09:37

Gerard LeBlond for redorbit.com - Your Universe Online Near-Earth Asteroids (NEAs) are space rocks that will pass close by our planet with a potential risk of impact. NASA, astronomers and scientists search the sky continually for these types of asteroids. Now, with the launch of Asteroid Zoo, the general public can assist in the search for undiscovered NEAs. Asteroid Zoo was launched on June 24, 2014 by Planetary Resources and Zooniverse allowing the general public, citizen scientists...

NASA Discusses Progress Reached So Far In Future Asteroid Mission
2014-06-20 12:35:12

Brett Smith for redOrbit.com - Your Universe Online Proposed studies for NASA’s missions to capture and redirect an asteroid are set to kick off in July. The space agency said these studies should inform not only the future asteroid mission, but also future missions to Mars. "With these system concept studies, we are taking the next steps to develop capabilities needed to send humans deeper into space than ever before, and ultimately to Mars, while testing new techniques to protect...

Asteroid Grand Challenge First Anniversary

NASA It’s been a busy year around the sun for NASA’s Asteroid Grand Challenge. NASA has been active in learning new ways to find, track and characterize asteroids and thinking about ways to respond to asteroid threats to human population. If you want to help, there are lots of opportunities, including a virtual workshop in celebration of the first anniversary of the public announcement of NASA’s Asteroid Grand Challenge on June 19-20. On June 18, 2013, NASA announced the Asteroid...

WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts to study in the 2020s -- all on the agency's human Path to Mars. Agency officials announced on Thursday recent progress to identify candidate asteroids for its Asteroid Redirect Mission (ARM), increase public participation in the search for asteroids, and advance the mission's design....

Whitney Clavin, Jet Propulsion Laboratory Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision...

The 1-2:30 p.m. EDT event will kick off a two-day virtual workshop to highlight successes and new opportunities through NASA's Asteroid Grand Challenge, which coincides with its first anniversary....

Asteroid 2014 HQ124
2014-06-13 11:15:52

Gerard LeBlond for redOrbit.com - Your Universe Online An asteroid, designated “2014 HQ124” at least 1,200 feet wide on its long axis, passed by Earth on June 8, 2014. It came within 776,000 miles, or approximately three times the distance to the moon. Images captured of the asteroid are some of the most detailed in NASA’s history. The asteroid was first spotted on April 23, 2014 by NASA’s NEOWISE mission. NEOWISE was adapted for capturing infrared light emitted from comets and...

Brett Smith for redOrbit.com - Your Universe Online Last year, a massive asteroid that had gone undetected exploded over Chelyabinsk, Russia in a huge fireball and another, much bigger asteroid spotted in April is expected to buzz past Earth this weekend. While the incoming HQ124 asteroid, aka “the Beast,” is not expected to make contact with the Earth’s atmosphere, professional skywatchers will be keeping close tabs on the massive space rock nonetheless. “What’s...

Chelyabinsk Meteor Collided With Asteroid Before Hitting Earth

Lawrence LeBlond for redOrbit.com - Your Universe Online A wealth of research has come following the Chelyabinsk meteor that exploded over Russia’s Ural Mountains on February 15, 2013. The latest study, which comes from scientists at the University of Tohoku in Japan, claims that the meteor collided with an asteroid before heading on its collision course with Earth. Analysis of a mineral called jadeite found embedded in fragments recovered after the explosion show that the parent body...

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...

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...

  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
