NASA's Space Launch System (SLS) is facing a precarious future amidst congressional discussions that could limit its operational flights from seven to five, with strong opposition from the Biden administration favoring cost-effective alternatives. Recent tests of necessary propulsion hardware showed mixed results; while the testing of the RS-25 engine went well, a test firing for a new solid rocket booster ended catastrophically when its nozzle shattered. These developments cast doubt on the SLS's viability as the backbone for NASA's Artemis program to return astronauts to the Moon.
NASA's Space Launch System faces an uncertain future, with potential cancellations looming after only five planned flights amid shifting priorities towards cheaper commercial space options.
The recent test of a new solid rocket booster revealed significant issues, including a catastrophic failure of the exhaust nozzle, raising concerns about the SLS's reliability.
