Coronavirus delays the launch of NASA's James Webb Space Telescope
NASA has again delayed the launch of its James Webb Space Telescope, this time because of how coronavirus has impacted work crews, Space.com The telescope was scheduled for launch in March 2021 after a number of delays. "We will not launch in March," Zurbuchen said.
NASA decommissions Spitzer Space Telescope after 16 years of service
NASA is flipping the switch on the Spitzer Space Telescope today. The observatory has made groundbreaking discoveries about the universe since its launch in 2003, from imaging some of the oldest stars in the universe to detecting the light reflected by exoplanets. The Spitzer was previously scheduled to go offline in 2018, but has continued operating due to NASA's followup telescope being postponed. With the James Webb Space Telescope nearing completion, Spitzer's mission is over.
A lawsuit almost stalled NASA's Cassini mission
Capt. Scott Kelly wasn't kidding when he famously quipped that "space is hard." Even getting to the launch pad can prove to be a daunting challenge. Take the Cassini mission to study Saturn, for example. Despite an investment of $3.4 billion and nearly a decade of development, Cassini wound up being very nearly scuttled at the last minute by protesters who thought they knew better than a federal agency that has put multiple men on the moon. Geez guys, it was just 73 pounds of plutonium riding aboard that Saturn orbiter -- it wouldn't have caused that much damage had something gone horribly wrong at launch.
James Webb Space Telescope ready for its wings, on track for 2018 launch
What's a spacecraft need wings for? Packaging, of course. The James Webb Space telescope relies on a 21 foot diameter backplane mirror to steady it, but the assembly needs to fit inside of a 16.5 foot fairing to ride the rocket to the stars. A tight fit, to say the least. Fortunately, NASA technicians have just finished the mirror backplate support structure, a folding wing assembly designed with to safely collapse the beryllium mirror during flight, and expand it again in orbit. "This is another milestone that helps move Webb closer to its launch date in 2018," remarked Geoff Yoder, the program's director. Now that the wing assembly is finished, the team can focus on the support fixture for the instrument model, which will complete major construction and allow technicians to connect the finished pieces. We'll miss old Hubble, sure, but we're happy to see its successor pulling things together all the same.
Alt-week 8.25.12: robotic noses, Nodosaurs and Space X launches again
Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. All good things come to an end, they say. Thankfully, most bad things do, too. So while the rest of the world of tech is dealing with the fallout, and possible implications of patent law, over here in the wild party that is Alt, we're fist pumping at all the awesome weekly sci-tech fodder. For example, we've got a robo-nose that can sniff out nasties in the air, a 110-million-year-old footprint found in NASA's back yard, and not one, but two space stories to reflect on. There's a hidden joke in there too, come back once you've read through to find it. This is alt-week.
NASA to launch Hubble space telescope successor in 2018, will clean its room later
You know you're going to miss the Hubble Space Telescope once ceases operation and they let it simply burn up in orbit. But don't cry, dry your eye, the National Aeronautics and Space Administration has announced plans to put its successor, the James Webb Space Telescope, in orbit in 2018. The telescope, which will be 100 times more sensitive than the Hubble, faced being cut completely by a Congressional subcommittee earlier this year as a result of budget constraints given its $8.8 billion price tag. After much Capital Hill grilling over the project being billions over budget, NASA has moved is scheduled launch -- initially set for 2013 -- to October of 2018. Although not the best news, it'll still get up there and you can hug your Hubble plushie tightly tonight knowing distant worlds will be that much closer.
NASA shows off James Webb Space Telescope, the Hubble successor
With Hubble slowly winding down after years of service, NASA has now taken to talking up the telescope's successor, even going so far as to take a full-scale model of the James Webb Space Telescope (JWST) on the road. Currently on display outside the Smithsonian National Air and Space Museum in Washington, D.C., the model measures an impressive 80 feet long and 40 feet high, which you'll have to be content with until the actual telescope launches in June 2013 at a cost of $4.5 billion. Once deployed, the telescope will sit some 1.5 million kilometers (or 930,000 miles) from Earth, and be able to peer far deeper into space than Hubble is able to, thanks in large part to the JWST's ginormous foldable mirror (almost three times bigger than Hubble's). If you can't make it to the Smithsonian to check out the model, you can at least get a better look at it in the gallery of images below courtesy of NASA. %Gallery-3077%
