The tasks aren’t assured to come back to fruition. All 4 are a part of a not too long ago established Pioneers program that guarantees to assist comparatively new researchers conduct experiments, however solely as long as the mission suits below a $20 million value cap. Whereas that’s cheap in comparison with many NASA missions, there’s a probability the newly chosen ideas may lose out in the event that they run over finances.
Nonetheless, that problem is a part of the purpose. Ideally, NASA can’t solely eke extra astrophysics analysis out of restricted funding, however encourage extra artistic methods to conduct science. It’d scale back its reliance on standard satellites and the giant rockets used to get them to orbit.
