Pandora Mission
The Pandora Mission, Pandora SmallSat, or Pandora, is a proposed small satellite mission known as SmallSat, one of three orbital missions approved by NASA to pass to the next development phase in the Pioneers program. Te mission would intend to determine atmospheric compositions by observing exoplanets and their host stars at the same time in both visible and infrared light over long periods of time. The satellite will have sensitivity to identify exoplanets with hydrogen or water in present in their atmospheres, as well was what exoplanets are covered by clouds or hazes. Pandora will observe a minimum of 20 exoplanets, with sizes that range from Earth-size to Jupiter-size, and host stars ranging from mid-K to late-M spectral types.
