NASA has canceled a greenhouse gas monitoring mission once intended to fly as a commercial hosted payload after the mission lost its ride to orbit and suffered severe cost overruns.
An Earth science instrument selected by NASA several years ago to fly as a hosted payload on a commercial communications satellite may instead fly on a standalone spacecraft because of a lack of hosting opportunities.
A NASA Earth science hosted payload mission to study the planet’s carbon cycle has been confirmed for development, although exactly when and how it will fly have yet to be determined.
Greenhouse gas monitoring was a hot topic at the American Meteorological Society’s annual conference. International agencies shared plans for a global constellation and companies showcased a new generation of sensors.
