Two significant NASA objectives that have actually introduced in the previous year are exposing an interactions weak point in area.
NASA interacts with all of its remote spacecraft– from the Orion pill to the James Webb Space Telescope(Webb or JWST) to Voyager 1— through the Deep Space Network, a collection of 14 antennas situated at 3 websites in California, Spain and Australia. The network is hectic, and making sure that every objective beyond Earth orbit has the interactions time it requires can be difficult, a concern that the Artemis 1 objective has actually worsened.
” We were informed over the summer season that when the Artemis area objective released, the Deep Space Network was going to be generally completely taken by Artemis due to the fact that they required to monitor the spaceship,” Mercedes López-Morales, an astrophysicist at the Harvard Smithsonian Center for Astrophysics and the chair of the JWST Users Committee, informed a conference of the U.S. National Academies of Sciences’ Board on Physics and Astronomy on Wednesday (Nov. 30).

The time began Nov. 16, when NASA released Artemis 1 A test flight to begin the firm’s go back to the moon, the 25- day objective sent out an uncrewed Orion pill to lunar orbit and is set up to crash Earth on Dec. 11.
While Orion remains in flight and beyond low Earth orbit, it’s in near-constant contact with the Deep Space Network– a significant drain that has actually put the James Webb Space Telescope and other objectives in the rear seat. NASA has actually understood Artemis would strain the Deep Space Network; the company organized upgrades to some antennas and included 2 brand-new ones in January 2021 and March 2022 in preparation.
But interactions time is still limited. “It might be approximately 80 hours– that’s about 3 and a half days– of no contact with JWST at all,” López-Morales stated she was informed prior to Artemis 1’s launch.
JWST researchers normally send out commands to the $10 billion observatory about as soon as a week, she informed the board, so irregular interactions does not impact the observatory getting its guidelines. For astronomers to in fact delight in Webb’s power, the telescope requires to be able to beam house its information– and do so prior to its computer system fills up.
” The huge concern is that you can not download information for that long,” López-Morales stated.
For Artemis 1, she stated, the Space Telescope Science Institute in Maryland, which runs both JWST and the Hubble Space Telescope, rejiggered JWST’s observing schedule. Researchers focused on much shorter observations, which develop smaller sized batches of information, to lower the possibilities of the telescope’s computer system filling prior to the Deep Space Network can accept the next batch of information.
But since NASA prepares extra Artemis launches– and these with human beings aboard– in 2024 and beyond, researchers desire a various option to the interactions logjam.
” We are frantically asking NASA to come up with a strategy to in some way have more access to antennas,” López-Morales stated.
