New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

NASA’s New Horizons mission may shut down two instruments over lack of funding
Decision risks “incalculable loss” of data from the edge of the Sun’s influence, scientists say
