Expedition 71 Astronauts to Discuss Mission in NASA Welcome Home Event
Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from a mission aboard the International Space Station.
NASA astronauts Matthew Dominick, Mike Barratt, Jeanette Epps, and Tracy C. Dyson will share highlights from their mission beginning at 6 p.m. CST Wednesday, Dec. 4, during a free, public event at NASA Johnson Space Center’s official visitor center. The crew will also recognize key contributors to mission success in an awards ceremony following the presentation.
The astronauts will be available at 5 p.m. for media interviews before the event. Media may request an in-person interview no later than 5 p.m. Tuesday, Dec. 3, by emailing Dana Davis at dana.l.davis@nasa.gov.
Expedition 71
NASA’s SpaceX Crew-8 mission launched to the space station in March 2024 as the eighth commercial crew rotation mission. The crew spent 235 days in space, traveled 100 million miles, and completed 3,760 orbits around the Earth, splashing down off the coast of Pensacola, Florida, on Oct. 25, 2024. This was the first spaceflight for Dominick and Epps and the third spaceflight for Barratt, who has logged 447 days in space over the course of his career. The crew also saw the arrival and departure of eight visiting vehicles during their mission.
Dyson flew with an international crew, launching aboard the Soyuz MS-25 in March 2024. The six-month research mission was the third spaceflight of her career, and her second long-duration spaceflight. Dyson’s third spaceflight covered 2,944 orbits of the Earth and a journey of 78 million miles as an Expedition 70/71 flight engineer. She has now logged a total of 373 days in space, including more than 23 hours in four spacewalks. Dyson and her crewmembers landed safely in Kazakhstan on Sept. 24, 2024.
While aboard the station, the Expedition 71 crew contributed to hundreds of technology demonstrations and experiments including the bioprinting of human tissues. These higher quality tissues printed in microgravity could help advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions. The crew also looked at neurological organoids, created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson’s disease. The organoids provide a platform to study these diseases and their treatments and could help address how extended spaceflight affects the brain.

Summary of Aura 20th Anniversary Event
Snippets from The Earth Observer’s Editor’s Corner
The last of NASA’s three EOS Flagships – Aura – marked 20 years in orbit on July 15, 2024, with a celebration on September 18, 2024, at the Goddard Space Flight Center’s (GSFC) Recreational Center. The 120 attendees – including about 40 virtually – reminisced about Aura’s (originally named EOS-CHEM) tumultuous beginning, from the instrument and Principal Investigator (PI) selections up until the delayed launch at the Vandenberg Space Force Base (then Vandenberg Air Force Base) in California. They remembered how Bill Townsend, who was Deputy Director of GSFC at the time, and Ghassem Asrar, who was NASA’s Associate Administrator for Earth Science, spent many hours on site negotiating with the Vandenberg and Boeing launch teams in preparation for launch (after several delays and aborts). The Photo shows the Aura mission program scientist, project scientists (PS), and several instrument principal investigators (PI) shortly before launch.

The Aura (formerly EOS CHEM) mission program scientist, project scientists (PS), and several of instrument principal investigators (PI) at Vandenberg Space Force Base (then Air Force Base) shortly before launch on July 15, 2004. The individuals pictured [left to right] are Reinhold Beer [NASA/Jet Propulsion Laboratory (JPL)—Tropospheric Emission Spectrometer (TES) PI]; John Gille [University of Colorado, Boulder/National Center for Atmospheric Research (NCAR)—High Resolution Dynamics Limb Sounder (HIRDLS) PI]; Pieternel Levelt [Koninklijk Nederlands Meteorologisch Instituut (KNMI), Royal Netherlands Meteorological Institute—Ozone Monitoring Instrument (OMI) PI]; Ernest Hilsenrath [NASA’s Goddard Space Flight Center (GSFC)—Aura Deputy Scientist and U.S. OMI Co-PI];Anne Douglass [GSFC—Aura Deputy PS]; Mark Schoeberl [GSFC—Aura Project Scientist]; Joe Waters [NASA/JPL—Microwave Limb Sounder (MLS) PI]; P.K. Bhartia [GSFC—OMI Science Team Leader and former Aura Project Scientist]; and Phil DeCola [NASA Headquarters—Aura Program Scientist]. NOTE: Affiliations/titles listed for individuals named were those at the time of launch. Photo Credit: Ernest Hilsenrath At the anniversary event, Bryan Duncan [GSFC—Aura Project Scientist] gave formal opening remarks. Aura’s datasets have given a generation of scientists the most comprehensive global view of gases in Earth’s atmosphere to better understand the chemical and dynamic processes that shape their concentrations. Aura’s objective was to gather data to monitor Earth’s ozone layer, examine trends in global air pollutants, and measure the concentration of atmospheric constituents contributing to climate forcing. To read more about Aura’s incredible 20 years of accomplished air quality and climate science, see the anniversary article “Aura at 20 Years” in The Earth Observer.
Bill Guit [GSFC—Aqua and Aura Program Manager and former Aura Mission Operations Lead] gave brief remarks focusing on how Aura became part of the international Afternoon Constellation, or “A-Train,” of satellites, including Aqua, which launched in 2002, and joined by several other NASA and international missions. Aura and Aqua have provided data for over two decades of multidisciplinary Earth science discovery and enhancement.
Both current and former Aura instrument PIs gave brief remarks. Each discussed Aura’s scientific legacy and their instrument’s contributions. They thanked their engineering teams for the successful development and operation of their instruments, and the members of the instrument science teams for developing the algorithms, discovering new science, and demonstrating how the science will serve the public. The PIs were particularly grateful that their instruments or the variants thereof will continue to fly on current and/or future NASA science missions or on international operational satellites.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Shauntina Lilly, a NASA Glenn public affairs officer, speaks to students about NASA’s available internships and educational resources during the STEM Goes Red for Girls event at Great Lakes Science Center, home of the NASA Glenn Visitor Center, on Oct. 21.Credit: NASA/Debbie Welch NASA’s Glenn Research Center in Cleveland supported this year’s STEM Goes Red for Girls event at Great Lakes Science Center on Oct. 21. The program provides seventh and eighth grade students exposure to some of Greater Cleveland’s leading STEM companies. The event also featured a hands-on exhibitor fair, speed mentoring, and educational classes.
Hosted by the American Heart Association, this year’s event welcomed its largest audience to date with 352 students and educators from 32 schools within Northeast Ohio. NASA Glenn’s presence focused heavily on internships and career advice, but also highlighted the center’s work with the Space Communications and Navigation program’s Deep Space Network. Glenn’s Julie Sufka also served as a mentor, speaking to young girls about STEM opportunities in mathematics.
