NASA’s SpaceX Crew-9 members pose together for a portrait inside the vestibule between the International Space Station and the SpaceX Dragon crew spacecraft. Clockwise from left, are NASA astronauts Butch Wilmore, Nick Hague, and Suni Williams, and Roscosmos cosmonaut Aleksandr Gorbunov.NASA NASA will provide live coverage of the agency’s SpaceX Crew-9 return to Earth from the International Space Station, beginning with Dragon spacecraft hatch closure preparations at 10:45 p.m. EDT Monday, March 17.
NASA and SpaceX met on Sunday to assess weather and splashdown conditions off Florida’s coast for the return of the agency’s Crew-9 mission from the International Space Station. Mission managers are targeting an earlier Crew-9 return opportunity based on favorable conditions forecasted for the evening of Tuesday, March 18. The updated return target continues to allow the space station crew members time to complete handover duties while providing operational flexibility ahead of less favorable weather conditions expected for later in the week.
NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, as well as Roscosmos cosmonaut Aleksandr Gorbunov, are completing a long-duration science expedition aboard the orbiting laboratory and will return time-sensitive research to Earth.
Mission managers will continue monitoring weather conditions in the area, as Dragon’s undocking depends on various factors, including spacecraft readiness, recovery team readiness, weather, sea states, and other factors. NASA and SpaceX will confirm the specific splashdown location closer to the Crew-9 return.

For Crew-9 return, NASA’s live operations coverage is as follows (all times Eastern and subject to change based on real-time operations):
Monday, March 17
10:45 p.m. – Hatch closing coverage begins on NASA+
Tuesday, March 18
12:45 a.m. – Undocking coverage begins on NASA+
1:05 a.m. – Undocking
Following the conclusion of undocking coverage, NASA will switch to audio only.
Pending weather conditions at the splashdown sites, continuous coverage will resume on March 18 on NASA+ prior to the start of deorbit burn.
4:45 p.m. – Return coverage begins on NASA+
5:11 p.m. – Deorbit burn (time is approximate)
5:57 p.m. – Splashdown (time is approximate)
7:30 p.m. – Return-to-Earth media conference on NASA+, with the following participants:
Joel Montalbano, deputy associate administrator, NASA’ Space Operations Mission Directorate Steve Stich, manager, NASA’s Commercial Crew Program Jeff Arend, manager for systems engineering and integration, NASA’s International Space Station, NASA’s International Space Station Office Sarah Walker, director, Dragon Mission Management, SpaceX To participate in the briefing media must contact the newsroom at NASA Johnson Space Center in Houston by 5 p.m., March 17, at: jsccommu@mail.nasa.gov or 281-483-5111. To ask questions, media must dial in no later than 10 minutes before the start of the call. The agency’s media credentialing policy is available online.

Hubble Sees a Spiral and a Star

This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart. The star, marked with four long diffraction spikes, is in our own galaxy. It’s just 7,109 light-years away from Earth. The galaxy, named NGC 4900, lies about 45 million light-years from Earth.
This image combines data from two of Hubble’s instruments: the Advanced Camera for Surveys, installed in 2002 and still in operation today, and the older Wide Field and Planetary Camera 2, which was in use from 1993 to 2009. The data used here were taken more than 20 years apart for two different observing programs — a real testament to Hubble’s long scientific lifetime!
Both programs aimed to understand the demise of massive stars. In one, researchers studied the sites of past supernovae, aiming to estimate the masses of the stars that exploded and investigate how supernovae interact with their surroundings. They selected NGC 4900 for the study because it hosted a supernova named SN 1999br.
In the other program, researchers laid the groundwork for studying future supernovae by collecting images of more than 150 nearby galaxies. When researchers detect a supernova in one of these galaxies, they can refer to these images, examining the star at the location of the supernova. Identifying a supernova progenitor star in pre-explosion images gives valuable information about how, when, and why supernovae occur.
