The April 9, 2020 NASA press release NASA Astronaut Chris Cassidy, Crewmates Arrive Safely at Space Station mentions:

It is the third spaceflight for Cassidy and Ivanishin and the first for Vagner, who are scheduled to return to Earth in October after a mission of more than six months during which they will conduct about 160 science investigations in fields such as, biology, Earth science, human research, physical sciences, and technology development. Work on the unique microgravity laboratory advances scientific knowledge and demonstrates new technologies, making research breakthroughs that will enable long-duration human and robotic exploration of the Moon and Mars.

What scientific investigations into Earth Science will these three astronauts do between now and their return to Earth in October?

    $\begingroup$ If you go here nasa.gov/mission_pages/station/research/experiments/explorer/… you can filter the experiments by category and expedition (this one is 63). There are 16 results, but the category mixes Earth with Space science, and I think most results are ongoing experiments rather than brand new stuff. $\endgroup$ – Jean-Marie Prival Apr 10 '20 at 10:24

NASA Space Station Research Explorer allows to filter experiments by expedition and category. A query for expedition 63 and the "Earth and space science" category yields the following 17 results (as of 27 February 2021):

  • AMS-02 (Alpha Magnetic Spectrometer - 02)
  • ASIM (Atmosphere-Space Interactions Monitor)
  • ISS-CREAM (Cosmic Ray Energetics and Mass for the International Space Station)
  • CEO (Crew Earth Observations)
  • iSIM (Demonstration of integrated Standard Imager for Microsatellites)
  • ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station)
  • Tanpopo-2 (ExHAM-Astrobiology Japan-2)
  • GEDI (Global Ecosystem Dynamics Investigation)
  • HISUI (Hyper-Spectral Imager Suite)
  • NICER (Neutron Star Interior Composition Explorer)
  • OCO-3 (Orbiting Carbon Observatory-3)
  • STP-H6-NIRAC (Space Test Program-Houston 6-Near InfraRed Airglow Camera)
  • STP-H5 FPS (STP-H5-Fabry Perot Spectrometer for Methane)
  • STP-H5 LIS (STP-H5-Lightning Imaging Sensor)
  • SAGE III-ISS (Stratospheric Aerosol and Gas Experiment III-ISS)
  • SPOC (The Spectral Ocean Color (SPOC) Satellite)
  • Total & Spectral Solar Irradiance Sensor (TSIS) (Total and Spectral Solar Irradiance Sensor)

  • $\begingroup$ Wow, jackpot! Is "expedition 63" the mission that brought these, or the one that will execute or interact with the experiments. Sometimes it it's quite a while between something getting up there and it finally getting installed and up and running. $\endgroup$ – uhoh Feb 27 at 9:19

    $\begingroup$ Yes, like I said in the comment to the question, most results are ongoing experiments rather than brand new stuff. I'm not sure how to find out which are new, sorry. $\endgroup$ – Jean-Marie Prival Feb 27 at 9:26

    $\begingroup$ Actually if you click on the experiment name, then there is a page with some details, among which "ISS Expedition Duration" in the right panel. For example, SPOC seems to be new ("April 2020 — October 2020"). You just have to go through all seventeen! :) $\endgroup$ – Jean-Marie Prival Feb 27 at 9:31
  • $\begingroup$ Not to kill joy but those are sensors not research topics? $\endgroup$ – Winston Feb 27 at 20:17
  • $\begingroup$ @Exocytosis good point, I've asked "What scientific investigations into Earth Science will these three astronauts do between now and their return to Earth in October?" and while this provides a lot of insight and sources it's not a complete answer yet. $\endgroup$ – uhoh Mar 1 at 5:27
