    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...

  • Billions of Taxpayer Dollars Burn in SpaceX Rocket Explosion

    Thursday’s explosion of a SpaceX rocket at Cape Canaveral is a reminder of just how easily billions of dollars in government subsidies can go up in flames.While the media reported the event as a mere setback for billionaire SpaceX CEO Elon Musk and “a major blow” to Facebook CEO Mark Zuckerberg’s plans for expanding internet services in Africa, it is clear that the biggest looser is the American taxpayer.Musk’s SpaceX, together with his other high-profile ventures like Tesla Motors and SolarCity are supported heavily by a litany of government subsidies, having received nearly $5 billion in taxpayer dollars.Although Musk’s ventures are pushing the boundaries of...

    NASA ^ | 30 Aug, 2016 | Wang et a
    A new record for the most distant galaxy cluster has been set using NASA’s Chandra X-ray Observatory and other telescopes. This galaxy cluster may have been caught right after birth, a brief, but important stage of evolution never seen before. The galaxy cluster is called CL J1001+0220 (CL J1001 for short) and is located about 11.1 billion light years from Earth. The discovery of this object pushes back the formation time of galaxy clusters – the largest structures in the Universe held together by gravity – by about 700 million years. “This galaxy cluster isn’t just remarkable for its distance,...

    Popular Mechanics ^ | 8/30/2016 | Avery Thompson
    On Saturday, astronomers discovered a new asteroid, just a few hours before it almost hit us. The asteroid is called 2016 QA2, and it missed the Earth by less than a quarter of the distance to the moon. That puts it about three times as far away from Earth as our farthest satellites. And we never saw it coming. So how did 2016 QA2 sneak up on us like that? For this particular asteroid, the answer seems to be that it has a very peculiar orbit. It's highly elliptical, which means it can usually be found hanging out by either...

    China has its sights set firmly on Mars and is aiming to launch its own rover to the red planet by 2020. New images have today provided the first glimpse of what this rover might look like when it launches at the end of the decade.

    Despite almost two years of silence, NASA never stopped searching for its long lost spacecraft STEREO-B. NASA announced Sunday that it had re-established contact with STEREO-B after communications were lost in October 2014. Contact with the spacecraft -- which works in tandem with a second spacecraft STEREO-A to study the sun -- was lost during a test of one of its timers. Launched in October 2006, the STEREO mission includes two spacecraft -- one ahead of Earth in its orbit, the other behind -- tasked with monitoring the flow of energy and matter from the sun to Earth.

    NASA’s Deep Space Network, or DSN, “established a lock on the STEREO-B (spacecraft’s) downlink carrier at 6:27 p.m. EDT,” NASA said in a statement. “The downlink signal was monitored by the Mission Operations team over several hours to characterize the attitude of the spacecraft and then transmitter high voltage was powered down to save battery power. ... Launched in 2006, the STEREO mission featured two spacecraft -- STEREO-A and STEREO-B -- designed to monitor solar activity from different locations, one “ahead” in its orbit and one “behind,” allowing scientists to see the entire star, not just the side facing Earth....

    NASA is dead set on leaving Low-Earth Orbit to go to the moon, Mars and other farther destinations. That means extending the space station's funding beyond 2024 is out of the question. Now, NASA Deputy Associate Administrator Bill Hill has revealed what the agency wants to do with the ISS once astronauts move out. Instead of deorbiting it and sinking it into the ocean or breaking it apart to sell piece by piece, it apparently wants to hand the spacecraft over to a private corporation.
  • Spacewalkers attach docking adapter to space station for commercial vehicles

    Attached to the station’s no-longer-needed shuttle port at the front of the station, the Boeing-built International Docking Adapter will allow spacecraft from both companies to bring crews to the outpost, ending NASA’s sole reliance on Russian Soyuz ferry ships. A second IDA is expected to be attached in 2018. “It is amazing that now we’ve opened up a new chapter in the story of the International Space Station, putting the front door on this for future commercial vehicles,” radioed station commander Jeff Williams, who worked with astronaut Kate Rubins to attach and outfit the IDA. “Congratulations to the entire team.”...
