More about space station crew

Full crew biographies are linked above. Below are highlights of their spaceflight experience.

NASA selected Tracy C. Dyson as an astronaut in June 1998, and during her previous two flights, she logged more than 188 days in space. Dyson first launched aboard the space shuttle Endeavour on STS-118 in 2007, serving as a mission specialist. During the mission, the crew added the starboard-5 truss segment to the station’s “backbone” and a new gyroscope. In 2010, Dyson served as flight engineer for Expedition 23/24 and performed three spacewalks, logging 22 hours and 49 minutes outside the station as she helped remove and replace a failed pump module for one of two external ammonia circulation loops that keep internal and external equipment cool.

Matthew Dominick will serve as commander for Crew-8, his first spaceflight after being selected as an astronaut in 2017. During Expedition 70/71 aboard the space station, he will serve as a mission specialist. Follow @dominickmatthew on X.

Michael Barratt is the Crew-8 pilot, making his third visit to the space station. In 2009, Barratt served as a flight engineer for Expeditions 19/20 as the station transitioned its standard crew complement from three to six, and performed two spacewalks. He flew aboard the space shuttle Discovery in 2011 on STS-133, which delivered the Permanent Multipurpose Module and fourth Express Logistics Carrier. Barratt has spent a total of 212 days in space. During Expedition 70/71, he will serve as a mission specialist.

Jeanette Epps was selected by NASA as an astronaut in 2009 and is a mission specialist aboard Crew-8, her first spaceflight, working with the commander and pilot to monitor the spacecraft during the dynamic launch and re-entry phases of flight.

Webb Shows Many Early Galaxies Looked Like Pool Noodles, Surfboards

Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author Viraj Pandya, a NASA Hubble Fellow at Columbia University in New York. “Galaxies that look like pool noodles or surfboards seem to be very common in the early universe, which is surprising, since they are uncommon nearby.”

The team focused on a vast field of near-infrared images delivered by Webb, known as the Cosmic Evolution Early Release Science (CEERS) Survey, plucking out galaxies that are estimated to exist when the universe was 600 million to 6 billion years old.

Image: Sample Shapes of Distant Galaxies

While most distant galaxies look like surfboards and pool noodles, others are shaped like frisbees and volleyballs. The “volleyballs,” or sphere-shaped galaxies, appear the most compact type on the cosmic “ocean” and were also the least frequently identified. The frisbees were found to be as large as the surfboard- and pool noodle-shaped galaxies along the “horizon,” but become more common closer to “shore” in the nearby universe. (Compare them in this illustration.)

Which category would our Milky Way galaxy fall into if we were able to wind the clock back by billions of years? “Our best guess is that it might have appeared more like a surfboard,” said co-author Haowen Zhang, a PhD candidate at the University of Arizona in Tucson. This hypothesis is based partly on new evidence from Webb – theorists have “wound back the clock” to estimate the Milky Way’s mass billions of years ago, which correlates with shape at that time.

These distant galaxies are also far less massive than nearby spirals and ellipticals – they are precursors to more massive galaxies like our own. “In the early universe, galaxies had had far less time to grow,” said Kartheik Iyer, a co-author and NASA Hubble Fellow also at Columbia University. “Identifying additional categories for early galaxies is exciting – there’s a lot more to analyze now. We can now study how galaxies’ shapes relate to how they look and better project how they formed in much more detail.”

Webb’s sensitivity, high-resolution images, and specialization in infrared light allowed the team to make quick work of characterizing many CEERS galaxies, and model their 3D geometries. Pandya also says their work wouldn’t be possible without the extensive research astronomers have done using NASA’s Hubble Space Telescope.

For decades, Hubble has wowed us with images of some of the earliest galaxies, beginning with its first “deep field” in 1995 and continuing with a seminal survey known as Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. Deep sky surveys like these led to far greater statistics, leading astronomers to create robust 3D models of distant galaxies over all of cosmic time. Today, Webb is helping to enhance these efforts, adding a bounty of distant galaxies beyond Hubble’s reach and revealing the early universe in far greater detail than previously possible.

Webb’s images of the early universe have acted like an ocean swell – delivering new waves of evidence. “Hubble has long showed an excess of elongated galaxies,” explained co-author Marc Huertas-Company, a faculty research scientist at the Institute of Astrophysics on the Canary Islands. But researchers still wondered: Would additional detail show up better with sensitivity to infrared light? “Webb confirmed that Hubble didn’t miss any additional features in the galaxies they both observed. Plus, Webb showed us many more distant galaxies with similar shapes, all in great detail.”

There are still gaps in our knowledge – researchers not only need an even larger sample size from Webb to further refine the properties and precise locations of distant galaxies, they will also need to spend ample time tweaking and updating their models to better reflect the precise geometries of distant galaxies. “These are early results,” said co-author Elizabeth McGrath, an associate professor at Colby College in Waterville, Maine. “We need to delve more deeply into the data to figure out what’s going on, but we’re very excited about these early trends.”

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Expedition 69 Crew, Three NASA Astronauts to Share Mission Highlights

Jan. 16, 2024

RELEASE: 24-001

Four astronauts, including the current record holder for the longest single U.S. stay in space aboard the International Space Station, will make their first public appearance in Houston since returning to Earth. The crew also will be available for interviews before the event at 5 p.m. CST Thursday, Jan. 18, at Space Center Houston.

Expedition 69 NASA astronauts Stephen Bowen, Woody Hoburg, and Frank Rubio, along with United Arab Emirates (UAE) astronaut Sultan Alneyadi, will be at NASA Johnson Space Center in Houston official visitor center to share accomplishments from their mission during a free, public event at 5:30 p.m. At 7 p.m., the crew, along NASA leadership, will help recognize key contributors to the mission’s success in an awards ceremony.

Reporters may request an in-person interview no later than 12 p.m. Jan. 18 by emailing Dana Davis at dana.l.davis@nasa.gov.  

Expedition 69

NASA’s SpaceX Crew-6 mission launched in March 2023 with Bowen, Hoburg, and Alneyadi, as well as Roscosmos cosmonaut Andrey Fedyaev, on the sixth commercial crew rotation mission to the space station. The crew spent 186 days in orbit, traveled 78,875,292 miles, and completed 2,976 Earth orbits, splashing down off the coast of Jacksonville, Florida, on Sept. 4, 2023. This was Bowen’s fourth spaceflight and the first spaceflight for Hoburg, Alneyadi, and Fedyaev. The crew helped improve power systems for the space station through a series of spacewalks. In June 2023, Bowen completed his 10th career spacewalk, tying the U.S. record for number of spacewalks. Alneyadi also completed the first long-duration mission for a UAE astronaut.

The Dragon crew was welcomed aboard the station by the international crew that flew on the Soyuz spacecraft and served on Expeditions 68 and 69. NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin launched six months earlier, on the Soyuz MS-22 spacecraft in September 2022. The Soyuz crew spent a total of 371 days aboard the space station, traveled 157,412,306 statute miles, and completed 5,963 Earth orbits, landing in Kazakhstan aboard the Soyuz MS-23 spacecraft on Sept. 27, 2023. This was the second spaceflight for Prokopyev and Petelin. This was Rubio’s first spaceflight mission and it broke the U.S. record for a single spaceflight by an American.

While aboard the station, the Expedition 69 crew contributed to hundreds of experiments and technology demonstrations, including conducting a student robotic challenge, studying plant genetic adaptations to space, and monitoring human health in microgravity to prepare for exploration beyond low Earth orbit and to benefit life on Earth. The crew released Saskatchewan’s first satellite, which tests a new radiation detection and protection system derived from Melanin that’s found in many organisms including humans.
