    More space rocks seem to be approaching Earth’s territory, and a new report reveals another one may bring in disasters. NASA has spotted an asteroid traveling at 63,000 miles per hour, and there is a possibility that it can impact the Earth. Express reports that the space agency recently tracked down an asteroid named 101955 Bennu but formally known as 1999 RQ36, hurtling towards Earth at a rapid speed of 63,000 miles per hour. NASA has not only labeled this a Potentially Hazardous Object or PHO, but they have also classified RQ36 with the second-highest rating on the Palermo Technical...
  • Watch NASA's OSIRIS-REx Rendezvous With an Asteroid: The spacecraft arrives at the tiniest [tr]

    NASA’s OSIRIS-REx spacecraft was launched in 2016, but today it will begin to orbit its destination: the asteroid Bennu. When it does, Benniu will break the record for the smallest object ever orbited by a manmade spacecraft. NASA will begin a process of learning more about the small asteroids that reside in our part of the solar system. You can watch the livestream of the arrival here:

    NASA’s OSIRIS-REx spacecraft is scheduled to rendezvous with its targeted asteroid, Bennu, on Monday, December 3, 2018, at approximately 17:00 UTC (noon EST). Translate UTC to your time. NASA will air a live event from 16:45 to 17:15 UTC (11:45 a.m.to 12:15 p.m. EST) to highlight the arrival of the agency’s first asteroid sample return mission. You can watch on NASA TV, Facebook Live, Ustream, YouTube and NASA Live. NASA TV also will air an arrival preview program starting at 16:15 UTC (11:15 a.m. EST). OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) launched in September 2016 and has been...

    The OSIRIS-REx spacecraft began its final approach toward the big near-Earth asteroid Bennu on Friday (Aug. 17), NASA officials said. The milestone also marks the official start of OSIRIS-REx's "asteroid operations" mission phase, they added. OSIRIS-REx is still about 1.2 million miles (2 million kilometers) from Bennu and won't arrive in orbit around the 1,650-foot-wide (500 meters) space rock until Dec. 3. The $800 million OSIRIS-REx mission — whose name is short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer — launched on Sept. 8, 2016, from Cape Canaveral Air Force Station in Florida. If all goes according to...
  • NASA asteroid probe may find clues to origins of life on Earth (Bennu, time capsule of our origins)

    CAPE CANAVERAL, Fla. (Reuters) - A U.S. space probe was cleared for launch on Thursday to collect and return samples from an asteroid in hopes of learning more about the origins of life on Earth and perhaps elsewhere in the solar system, NASA said on Tuesday. A United Launch Alliance Atlas 5 rocket was scheduled to blast off from Cape Canaveral Air Force Station in Florida to dispatch the robot explorer Osiris-Rex on a seven-year mission. United Launch Alliance is a partnership of Lockheed-Martin and Boeing. Osiris-Rex is headed to a 1,640-foot (500-meter) wide asteroid named Bennu, which circles the...
  • NASA plans to launch study of asteroid that could destroy Earth (Bennu in 2135 scenario)

    Paging Bruce Willis! NASA is planning to launch a probe to study an asteroid that could one day pulverize the Earth. The asteroid, named Bennu, crosses Earth’s orbit once every six years and has gotten ever closer since it was discovered in 1999, astronomers told the Sunday Times of London (paywall). In 2135, Bennu will fly between the moon and Earth — a hair’s breadth in space terms, the Times reported. That’s so close that gravity from the Earth could effect Bennu’s orbit, “potentially putting it on course for the Earth later that century,” said Dante Lauretta, a professor of...

    Scientists on NASA's asteroid sample return mission, Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx), have measured the orbit of their destination asteroid, 1999 RQ36, with such accuracy they were able to directly measure the drift resulting from a subtle but important force called the Yarkovsky effect -- the slight push created when the asteroid absorbs sunlight and re-emits that energy as heat... Observations that Michael Nolan at Arecibo Observatory in Puerto Rico made in September 2011, along with Arecibo and Goldstone radar observations made in 1999 and 2005, when 1999 RQ36 passed much closer to Earth, show that...
