NASA's Parker Solar Probe began its fourth solar encounter on Jan 23, 2020, at 9:00 a.m. EST, at a distance of about 23.3 million miles from the Sun's surface.

The Expedition 61 spacewalking team aboard the International Space Station is taking a light-duty day ahead of this weekend’s excursion. Meanwhile, the Russian space residents researched human biology and prepared for a crew departure early next month. Astronauts Andrew Morgan and Luca Parmitano took it easy on Tuesday, relaxing before they begin a six-hour spacewalk …

By Ellen Gray / NASA'S WALLOPS FLIGHT FACILITY, VIRGINIA/ Nothing to be done. When your field campaign depends on chasing winter storms you have to wait for the weather to arrive in its own time. For the science team of the Investigation of Microphysics Precipitation for Atlantic Coast-Threatening Snowstorms, or IMPACTS, campaign that means carefully …

Food Acceptability: The crew completed a Food Acceptability Survey using the Data Collection Tool on an SSC (Station Support Computer). This investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system.  Results will be used in developing strategies to improve food system composition to support crew health …

The Expedition 61 astronauts have one more spacewalk planned this weekend and they will finish the repair of a cosmic ray detector. This will be the ninth spacewalk for the crew, more than in any other increment in the history of the International Space Station. NASA astronauts Jessica Meir and Christina Koch have turned their …

HERMES:  The crew performed the periodic vacuum valve opening for HERMES.  These operations maintain the desired vacuum levels for the granular/regolith experiments typically hosted by the HERMES facility.  Hermes is a reconfigurable on-orbit facility capable of accommodating up to four user-configurable experiment volumes at a time. The facility provides long duration exposure to microgravity, vacuum …

At 1:33 p.m. EST, Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA concluded their third spacewalk together. During the six hour and 58-minute spacewalk, the two NASA astronauts successfully completed the battery upgrade for one channel on one pair of the station’s solar arrays. Today’s work included removing the last two nickel-hydrogen batteries from this area …

Two NASA astronauts switched their spacesuits to battery power this morning at 6:35 a.m. EST to begin today’s spacewalk. Expedition 61 Flight Engineers Jessica Meir and Christina Koch are entering into the vacuum of space for about six-and-a-half-hours to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store and distribute power generated by the station’s solar arrays …

Two NASA astronauts switched their spacesuits to battery power this morning at 6:35 a.m. EST Expedition 61 Flight Engineers Christina Koch and Jessica Meir are venturing out into the vacuum of space for about six-and-a-half hours to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store and distribute power generated by the station’s solar arrays on …

Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA are scheduled to begin a spacewalk outside of the International Space Station at 6:50 a.m. EST Monday, Jan. 20. Live coverage of the spacewalk will begin at 5:30 a.m. on NASA Television and the agency’s website. This is the second of two battery replacement spacewalks in five …
