    PACE Successfully Completes Key Environmental Test

    Centered in the screen is the observatory, covered in a reflective foil-like material. The observatory is being lowered into a dark, hollow, circular chamber, the TVAC testing chamber.

    Consider it the "mother of all tests." This summer, the PACE spacecraft (short for Plankton, Aerosol, Cloud, ocean Ecosystem) completed a critical phase of its launch journey: the thermal vacuum test (TVAC), where it was subjected to extreme temperatures and pressures in a specialized chamber at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The …

    Six Weeks at Sea: NASA Scientists Double-Check Satellite Ocean Color Data

    An artist created visual of the globe is centered in the picture. All land on the image appears as a gray color, while the ocean is watercolored in shades of green, purple, and blue. The colors indicate the levels of chlorophyll in an area. Yellows and greens indicate higher levels, while purples and blues indicate lower levels.

    NASA researcher Joaquin Chaves calls it "ground truthing," even though land is nowhere in sight. This spring, Chaves boarded the Atlantic Meridional Transect (AMT) research cruise for six weeks of sampling water and taking measurements as the ship traversed the Atlantic Ocean. His team, based at NASA's Goddard Space Flight Center in Greenbelt, Maryland, uses …

    NASA’s PACE Spacecraft Assembled, Advances Toward Launch

    Although PACE was formally authorized in 2015, its concept has been on the minds of NASA Earth scientists for over 21 years. In 2023, that concept is now an assembled spacecraft at NASA's Goddard Space Flight Center in Greenbelt, Maryland. This past month, the PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission advanced closer to launch, …

    NASA’s PACE Mission Undergoes Milestone Testing

    NASA's PACE mission, which will provide a major boost to scientists studying Earth's atmosphere and ocean health, completed a milestone test in October at the agency's Goddard Space Flight Center in Greenbelt, Maryland. The Ocean Color Instrument (OCI) on the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission passed thermal vacuum tests to ensure it can …
