While Europa Clipper isn’t searching for extraterrestrial life, As a substitute for its workforce, its ultimate goal is to assess the moon’s potential habitability – how well it could support life. The probe will utilize its suite of instruments, including cameras, spectrometers, magnetometers, and radars, to collect data on chemical, biological, and geological composition through a series of flybys? The prospect of discovering life beyond Earth’s bounds, as potentially harbored by Jupiter’s icy moon Europa, could warrant a mission to explore its surface and subsurface. 

Last October, everything came together as planned for a deliberate rollout. In July, mission workforce members caught wind of a potential issue affecting Europa Clipper’s electronic systems. Preliminary data suggested that the spacecraft’s transistors, responsible for managing the flow of electrical energy within the probe, would be incapable of withstanding the intense radiation comprising charged particles confined within Jupiter’s formidable magnetic field – a force 20,000 times more potent than its Earthly counterpart. 

NASA announced that the mission workforce was informed that components were failing at lower-than-expected radiation levels. Disassembly of the spacecraft and replacing faulty transistors could have potentially moved the mission’s launch date forward to earlier than scheduled in October. 

After a rigorous series of tests conducted over several months at NASA’s Jet Propulsion Laboratory, Goddard Space Flight Center, and Applied Physics Laboratory, scientists have confirmed that even in the event of potential transistor damage, the impact on mission operations would be negligible. The team concluded that heating transistors could potentially accelerate recovery from injury, and the 20-day intervals between intense radiation exposure sessions allowed for adequate rejuvenation. To detect potential malfunctions, the spacecraft incorporates a network of transistors designed to alert the monitoring team to any anomalies, much like the use of canary sensors in coal mines to gauge toxic gas levels. The Europa Clipper mission successfully cleared a significant hurdle on September 9, achieving the coveted Key Choice Level E milestone, thereby securing its spot in the launch queue. 

Following its arrival in orbit around Jupiter, the Europa Clipper will undertake a total of 49 close flybys of Europa. At its closest point, the spacecraft is poised to descend as low as 16 miles (26 kilometers) above the Martian surface, enabling it to gather highly detailed observations.
