This event marked a key milestone in preparing the observatory for launch later this year. "We are desperately asking NASA to come up with a plan to somehow have more access to antennas," López-Morales said.Įmail Meghan Bartels at or follow her on Twitter meghanbartels. For the last time while it is on Earth, the world’s largest and most powerful space science telescope opened its iconic primary mirror. Scientists prioritized shorter observations, which create smaller batches of data, to reduce the chances of the telescope's computer filling up before the Deep Space Network can accept the next batch of data.īut because NASA plans additional Artemis launches - and these with humans aboard - in 2024 and beyond, scientists want a different solution to the communications logjam. So whatever happens next for Webb, including its journey to the launch site in. James Webb Space Telescope view of Saturn's weirdest moon Titan thrills scientistsįor Artemis 1, she said, the Space Telescope Science Institute in Maryland, which operates both JWST and the Hubble Space Telescope, rejiggered JWST's observing schedule. At this point in time, the ground-breaking space telescope has cost around 10 billion USD. James Webb Space Telescope peers into lonely dwarf galaxy with sparkling results The James Webb Space Telescope is revealing the earliest galaxies of the universe like never before, scientists say The James Webb Space Telescope (sometimes called Webb or JWST) is a large infrared telescope with a 6.5-meter primary mirror. "The big issue is that you cannot download data for that long," López-Morales said. (ESA/CNES/Arianespace) The next few months will be critical to its success, said Amber. But for astronomers to actually enjoy Webb's power, the telescope needs to be able to beam home its data - and do so before its computer fills up. The James Webb Space Telescope will launch on 25 December on board an Ariane 5 rocket from French Guiana. JWST scientists usually send commands to the $10 billion observatory about once a week, she told the board, so infrequent communications doesn't affect the observatory getting its instructions. "It could be up to 80 hours - that's about three and a half days - of no contact with JWST at all," López-Morales said she was told before Artemis 1's launch. NASA has known Artemis would strain the Deep Space Network the agency arranged upgrades to some antennas and added two new ones in January 2021 and March 2022 in preparation.īut communications time is still scarce. While Orion is in flight and beyond low Earth orbit, it's in near-constant contact with the Deep Space Network - a major drain that has put the James Webb Space Telescope and other missions in the backseat. Though less complex, the telescope became more expensive, with the price tag swelling to 4.5 billion, and NASA officials estimated a new launch date in 2013.
