Forced to find nearly $30 million in cost savings, NASA’s astrophysics program has trimmed budget reserves on one mission approaching launch and delayed the schedule of another.
NASA’s James Webb Space Telescope is facing a schedule conflict for its Ariane 5 launch with a European planetary science mission that could, in one scenario, delay the telescope’s launch by several months.
As NASA prepares to resume vibration testing of the James Webb Space Telescope after an anomaly last month, it’s asking astronomers to start developing proposals for observations to be carried out by the observatory after its launch.
Engineers installed the first of 18 beryllium-coated mirror segments that will make up the James Webb Space Telescope’s 6.5-meter primary mirror.
The James Webb Space Telescope’s Nobel Prize-winning head astronomer advised planetary scientists to get started on proposals for focusing JWST’s 6.5-meter mirror on objects most closer to home than its usual cosmic quarry.
Self-described "Hubble hugger" John Grunsfeld is at the tiller of NASA’s $5 billion-a-year Science Mission Directorate at a time when the agency is celebrating great mission successes, recovering from great planning failures, and preparing to send more billion-dollar robotic spacecraft out into the solar system.
Northrop Grumman Aerospace Systems has apparently solved technical problems plaguing the James Webb Space Telescope’s cryogenic cooler and is ready to ship the hardware to NASA for environmental testing, the U.S. space agency said.
Replacing faulty electrical wiring that runs behind the James Webb Space Telescope’s (JWST) primary mirror could delay assembly of the flagship observatory’s primary optics package, although the overall mission remains on schedule, a NASA official said April 8.
In another sign of the James Webb Space Telescope's dysfunction, Northrop Grumman denied a GAO request to interview programmatic technical experts unless a supervisor was present.
JWST prime Northrop Grumman last year denied what it has since characterized as an unprecedented request by the GAO for one-on-one interviews with employees overseeing key elements of the program, insisting instead that the workers’ supervisors be present.
The newest member of the House Appropriations subcommittee that funds NASA appears to be eyeing the James Webb Space Telescope’s budget wedge to fund human space exploration after JWST finally launches. A former NASA Astrophysics Division director says scientists should be concerned.
The cryogenic cooling system intended to chill one of Webb’s four primary science instruments is still causing problems for contractor Northrop Grumman and remains the top risk to an on-time launch in 2018.
