NASA’s Pluto Probe Could Lose 2 Key Instruments at a Crucial Moment As NASA's New Horizons spacecraft approaches the edge of our solar system, the mission team faces a peculiar problem.
Due to lack of funding, they may soon be forced to shut down two crucial instruments on board: PEPSSI and SWAP, the particle detectors responsible for understanding the outer boundaries of the solar system.
These instruments are instrumental in studying the interaction between our solar wind and interstellar material at the heliosphere's termination shock and heliopause.
