NASA's Europa Clipper Faces Radiation Challenges Ahead of Launch

Critical transistor vulnerabilities threaten the mission's success as NASA races to resolve the issue before the scheduled October launch.

Europa Clipper's transistors may not withstand Jupiter's intense radiation, raising mission risks.
Testing reveals some transistors fail at lower radiation levels than anticipated.
NASA is evaluating options to maximize transistor longevity in the harsh Jovian environment.
Delays could push the launch to 2025 or 2026, increasing mission costs.
A preliminary analysis of the transistor issue is expected by late July.
