NASA's James Webb Space Telescope faces the high probability of additional delays that could cause the telescope to exceed its cost cap, the U.S. Government Accountability Office warned in a Feb. 28 report.
A group of astronomers and engineers is seeking to convince NASA to study in-space servicing and assembly of future space telescopes, including the role the proposed Deep Space Gateway could play to support it.
Scientists gathering this week for the country’s largest astronomy meeting will discuss plans for future space telescopes, while raising questions about the status of upcoming missions.
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.
