In a new report, the federal department charged with analyzing how efficiently US taxpayer dollars are spent, the Government Accountability Office, says NASA lacks transparency on the true costs of its Space Launch System rocket program.

Published on Thursday, the new report (see.pdf) examines the billions of dollars spent by NASA on the development of the massive rocket, which made a successful debut launch in late 2022 with the Artemis I mission. Surprisingly, as part of the reporting process, NASA officials admitted the rocket was too expensive to support its lunar exploration efforts as part of the Artemis program.

“Senior NASA officials told GAO that at current cost levels, the SLS program is unaffordable,” the new report states.

The mission was successful, and Dimorphos’ orbit was shortened by 33 minutes in the weeks after the impact.

However, a team of high school students led by teacher Jonathan Swift at Thacher School in California have discovered that Dimorphos’ orbit continued to shrink by another minute more than a month after the collision.

‘The number we got was slightly larger, a change of 34 minutes,’ said Mr Swift. ‘That was inconsistent at an uncomfortable level.’

New details of the previously reported incident underscore how dependent the U.S. government has become on a company that once had to fight in court to become part of the Washington establishment.
