Students in Missouri will hear from NASA astronauts Jessica Meir and Jack Hathaway as they answer prerecorded science, technology, engineering, and mathematics (STEM) questions while aboard the International Space Station.

The Earth-to-space call will begin at 10:50 a.m. EDT Thursday, April 30, and will stream live on the agency’s Learn With NASA YouTube channel.

This event is hosted by the University of Missouri Pre-Employment Transition Services in Columbia, Missouri, for students in grades K-12 and members of the community. This opportunity aims to deepen understanding of space exploration and inspire students to pursue a future career in STEM.

Media interested in covering the event must RSVP by 5 p.m., Wednesday, April 29, to Kimberly Pudlowski at: 636-697-5845 or kimberly.gee@missouri.edu.

For more than 25 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN's (Space Communications and Navigation) Near Space Network.

Research and technology investigations taking place aboard the space station benefit people on Earth and support other agency work, including missions at the Moon. As part of NASA’s Artemis program, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.

NASA Shares SpaceX Crew-13 Assignments for Space Station Mission

APRIL 23, 2026

NASA Shares SpaceX Crew-13 Assignments for Space Station Mission

As part of NASA’s SpaceX Crew-13 mission, four crew members from three space agencies will launch no earlier than mid-September to the International Space Station for a long-duration science expedition.

NASA astronauts Jessica Watkins and Luke Delaney will serve as spacecraft commander and pilot, respectively. They will be joined by CSA (Canadian Space Agency) astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov, who will serve as mission specialists. After arriving at the orbiting laboratory, Crew-13 will become members of the space station’s Expedition 75.

This flight is the 13thcrew rotation with SpaceX to the space station as part of NASA’s Commercial Crew Program. NASA is advancing the launch date of Crew-13 from November to help increase the frequency of U.S. crew rotation missions to the space station. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars, and benefit people on Earth.

This will be the second flight to the space station for Watkins, who was selected as a NASA astronaut in 2017. Watkins grew up in Lafayette, Colorado, and earned an undergraduate degree in geological and environmental sciences from Stanford University, as well as a doctorate in geology from the University of California, Los Angeles. As a geologist, she studied the Martian surface and was a member of the Curiosity rover science team at NASA’s Jet Propulsion Laboratory in Southern California. Watkins first launched to the space station as a crew member aboard NASA’s SpaceX Crew-4 mission, spending a total of 170 days in space across Expeditions 67/68 in 2022. She will be the first NASA astronaut to launch aboard a SpaceX Dragon spacecraft twice.

Selected as a NASA astronaut in 2021, Delaney earned a bachelor’s degree in mechanical engineering at the University of North Florida and a master’s degree in aerospace engineering at the Naval Postgraduate School. The Florida native is a distinguished naval aviator who participated in exercises throughout the Asia Pacific region and conducted missions in support of Operation Enduring Freedom. As a test pilot, Delaney evaluated developmental aircraft systems and served as a test pilot instructor. He also worked as a research pilot at NASA’s Langley Research Center in Hampton, Virginia, where he supported airborne science missions. This is the first spaceflight for Delaney.

The Crew-13 mission also is the first spaceflight for Kutryk. Prior to his selection as a CSA astronaut in 2017, he served as a CF-18 fighter pilot, flying missions in support of Canada's NATO, U.N., and North American Aerospace Defense Command commitments. A native of Fort Saskatchewan, Alberta, Kutryk also worked as an experimental and operational test pilot at the Aerospace Engineering Test Establishment in Cold Lake, Alberta. Kutryk received a bachelor’s degree in mechanical engineering from the Royal Military College of Canada in Kingston, Ontario, and he is a distinguished graduate of the United States Air Force Test Pilot school in Edwards, California. He has master’s degrees in space studies, flight test engineering, and defense studies.

Crew-13 will be Teteryatnikov’s first trip to the orbiting laboratory. He graduated from the Naval Academy, St. Petersburg, Russia, in 2011 as an engineer specializing in ship power plant operations. Before his selection as a test cosmonaut, Teteryatnikov served in various naval engineering roles, including undersea vessels and specialized engine room operations. He was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that aren’t possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

NASA will host a news conference at 1:45 p.m. EDT Wednesday, April 29, from the agency’s Johnson Space Center in Houston to preview astronaut Anil Menon’s upcoming mission to the International Space Station.

Watch the news conference live on NASA’s YouTube channel. Learn how to watch NASA content through a variety of online platforms, including social media.

Following the news conference, individual interviews with Menon will begin at 3 p.m.

United States-based media interested in attending the news conference in person must contact the NASA Johnson newsroom at jsccommu@mail.nasa.gov by 5 p.m. Monday, April 27. U.S. and international media interested in participating by phone must contact NASA Johnson by 9:45 a.m. Thursday, April 23. A copy of NASA’s media accreditation policy is available online.

Requests for interviews with Menon should be submitted by 5 p.m., April 27. In-person interviews are limited to U.S. media. International media may request to conduct interviews virtually.

The Soyuz MS-29 mission, targeted to launch Tuesday, July 14, will carry Menon and his crewmates, Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina, to the International Space Station for an eight-month stay as part of Expeditions 74/75. It will be Menon’s first spaceflight.

Selected as a NASA astronaut in 2021, Menon graduated with the 23rd astronaut class in 2024. After completing initial astronaut candidate training, he began preparing for his first space station flight assignment.

Menon was born and raised in Minneapolis and is an emergency medicine physician, mechanical engineer, and lieutenant colonel in the United States Air Force. He holds a bachelor’s degree in neurobiology from Harvard University in Cambridge, Massachusetts. He also earned a master’s degree in mechanical engineering and a medical degree from Stanford University in Palo Alto, California. Menon completed his emergency medicine and aerospace medicine residency at Stanford and the University of Texas Medical Branch in Galveston, respectively.

Menon still actively practices emergency medicine at Memorial Hermann’s Texas Medical Center and teaches residents at the University of Texas’ residency program. For NASA, Menon also has served as an expedition flight surgeon for the agency’s crew members aboard the space station. Previously, Menon worked at SpaceX and served as the company’s first flight surgeon, helping to launch the first crewed Dragon spacecraft on NASA’s SpaceX Demo-2 mission in 2020 and building its medical organization to support humans on future missions.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a testbed for NASA to understand and overcome the challenges of long-duration spaceflight, expand commercial opportunities in low Earth orbit, and prepare for deep space missions to the Moon as part of the Artemis program in preparation for future human missions to Mars.
