Leicester astronomers look ahead to first light from James Webb Space Telescope


 E-Mail
Leicester space scientists will join a group of global experts investigating fundamental questions about our Universe, after being granted time to use the most advanced observatory ever built.
A total of 286 scientific targets identified by astronomers and planetary scientists at the University of Leicester were selected from more than 1,000 submitted by researchers from 44 countries, for a portion of the 6,000 observing hours available in the first year of operation (Cycle 1) for the James Webb Space Telescope (JWST).
Considered the successor to the Hubble Space Telescope, the JWST will launch in late 2021 and will begin delivering a flood of scientific data in 2022, after the spacecraft unfolds its 6.5m-diameter mirror, travels 1.5 million km from Earth, and checks the functioning of all of its instruments. ....

WASHINGTON: The Space Force is working to expand acquisition of commercial space services from satellite communications to include intelligence, surveillance and reconnaissance data and analysis, officials say.
“Comms, data relay, remote sensing, and even ISR and some other things [these] capabilities are increasingly available in the commercial market,” Space Force deputy Lt. Gen. DT Thompson told the 2021 C4ISR Conference today.
Thus, Space and Missile Systems Center (SMC) head Lt. Gen. JT Thompson (no relation to DT) and Clare Grason, who runs the Commercial Satellite Communications Office (CSCO) now “are looking to expand their responsibilities beyond just commercial SATCOM to the availability and use and procurement and provisioning of other commercial services,” he said. ....

WASHINGTON: DARPA’s effort to develop nuclear ‘engines’ for far-roving satellites also hopes to demonstrate the capability to keep “timely” tabs on spacecraft operating near the Moon, says program manager Maj. Nathan Greiner.
While cislunar surveillance doesn’t require nuclear-propulsion, such a spacecraft could move more rapidly into position to monitor targets of interest. It might also mean the spacecraft would be able to remain active for a longer period thanks to the fuel.
“Some of this is classified, so this answer must be rather general,” he said in an email, explaining that the Demonstration Rocket for Agile Cislunar Operations (DRACO) program has two key goals: ....
