NASA Space Mission Aims to Save Falling Telescope

NASA has launched a mission to intercept and stabilize a defunct space telescope that could re-enter Earth’s atmosphere within months, according to a statement from the agency’s Jet Propulsion Laboratory. The telescope, identified as the Solar Maximum Mission (SMM), was launched in 1980 to study solar activity but lost contact with ground control in 1989. Engineers confirmed its orbital decay accelerated in 2023, prompting the intervention.

The mission, managed by NASA’s Orbital Debris Remediation Office, involves a robotic spacecraft designed to dock with the SMM and either redirect its trajectory or deorbit it safely. A JPL spokesperson stated the effort is “critical to preventing potential debris hazards to populated regions.” The agency has not disclosed the exact timeline for the operation, citing ongoing technical evaluations.

Space debris experts have raised concerns about the SMM’s re-entry risk. Dr. Maria Gonzalez, a researcher at the European Space Agency’s Space Debris Office, noted the telescope’s titanium frame could survive atmospheric re-entry. “If it falls in a densely populated area, the consequences could be severe,” she said. ESA’s tracking data shows the SMM’s orbit is currently within a 120-kilometer range of Earth’s surface, with a 30% probability of re-entry by late 2024.

NASA’s plan includes a series of maneuvers to adjust the SMM’s trajectory using a propulsion module. The agency confirmed the module, developed in collaboration with SpaceX, is scheduled for a test launch in October 2024. A JPL engineer described the operation as “the most complex satellite retrieval since the Hubble servicing missions.” However, the agency has not addressed potential delays from the ongoing Artemis program’s resource allocation.

International space agencies have expressed mixed reactions. The Russian Space Agency’s director, Anatoly Petrov, called the mission “a necessary step for global space safety,” while the Chinese National Space Administration declined to comment. The United Nations Office for Outer Space Affairs has urged transparency, stating “any action affecting orbital debris must comply with international guidelines.”

The SMM’s potential re-entry has sparked public debate. Local officials in regions along its projected path, including parts of South America and the Pacific Islands, have initiated emergency preparedness drills. A Chilean civil defense official said, “We are coordinating with NASA to ensure our teams are ready if the worst-case scenario occurs.” No official evacuation plans have been announced.

NASA’s decision to intervene follows a 2022 report by the National Academy of Sciences, which highlighted the growing risk of uncontrolled satellite re-entries. The agency’s current budget for orbital debris mitigation includes $250 million allocated for the SMM mission, according to a 2023 federal spending document. The project’s total cost remains undisclosed.

The SMM’s fate remains uncertain. A JPL update on August 15 noted “unpredictable atmospheric conditions” could alter its trajectory. The agency has scheduled a public briefing for September 5 to provide further details. Until then, the telescope’s next move will be monitored by a global network of ground-based radar systems.
