NASA will host a public event featuring three crew members from the agency’s SpaceX Crew-11 mission at 11 a.m. EDT Monday, June 1. The event, which takes place during the crew’s standard postflight visit, will be held in the Webb Auditorium at NASA Headquarters in the Mary W. Jackson building, 300 E. Street SW in Washington.
The crew members, including NASA astronauts Zena Cardman and Mike Fincke and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, will discuss their recent 167-day mission aboard the International Space Station, where they conducted a wide range of science experiments to benefit life on Earth and advance human space exploration as part of International Space Station Expedition 73/74.
The Crew-11 mission lifted off on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew’s SpaceX Dragon spacecraft docked to the orbital outpost on Aug. 2.
During their mission, the three astronauts, along with crewmate Roscosmos cosmonaut Oleg Platonov, traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space. The crew members returned to Earth on Jan. 15, splashing down off the coast of San Diego.
Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.
Media interested in attending the event must RSVP by 8 a.m., June 1, by emailing the NASA Headquarters newsroom at hq-media@mail.nasa.gov. NASA’s media accreditation policy is online. Based on the crew’s schedule, NASA will not be able to accommodate interviews.
This opportunity also is part of NASA’s Frontiers Forum: Voices Shaping the Future of Space speaking series designed to convene bold thinkers and senior leaders at the forefront of exploration and innovation. The series will spotlight mission-critical priorities from advancing the Artemis campaign and strengthening commercial partnerships to shaping the future workforce and accelerating breakthrough technologies. The agency will share more details soon.

Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have completed their final inspection of a key element for the agency’s Nancy Grace Roman Space Telescope: the primary mirror. This 7.9-foot (2.4-meter) mirror will collect and focus light from cosmic objects near and far, helping Roman capture stunning panoramas of space.
“The Roman engineering team laid eyes on the telescope for the final time before it, in turn, becomes the eyes of humanity, revealing the wonders of the cosmos,” said J. Scott Smith, the Roman telescope manager at NASA Goddard. “It is a profoundly humbling moment to witness the culmination of hard work from so many dedicated individuals, teams, and partner organizations, including L3Harris.”
On May 20, engineers turned the Roman observatory onto its side and deployed the “hood” that will be stowed for launch to protect the mirror. Then the team conducted a meticulous visual inspection to ensure no specks fell onto the mirrors during testing and confirm there are no defects in the coating or alignment.
“We developed a method of using a high-resolution camera equipped with a very powerful zoom lens to do a multi-purpose inspection,” said Bente Eegholm, optics lead for Roman’s Optical Telescope Assembly at NASA Goddard. “The mirror passed with flying colors, keeping the mission on track for an early September launch.”
The team carefully observed the optics along the path light will follow to the Wide Field Instrument detector array and confirmed it remains in proper alignment following the observatory shake test.
“In order to gather very sensitive measurements of objects strewn throughout space, all of Roman’s components have to be ultraprecise,” Eegholm said. “The primary mirror certainly delivers on that precision.”
Roman’s primary mirror sports a layer of silver less than 400 nanometers thick — about 200 times thinner than a human hair. The silver coating was specifically chosen for Roman because of how well it reflects near-infrared light. By contrast, the Hubble Space Telescope’s mirror is coated with layers of aluminum and magnesium fluoride to optimize visible and ultraviolet light reflectivity. Likewise, the James Webb Space Telescope’s mirrors have a gold coating to suit its longer wavelength infrared observations.
The Roman mirror is so finely polished that the average bump on its surface is only 1.2 nanometers tall — more than twice as smooth as the mission requires. If the mirror were scaled up to Earth’s size, these bumps would be just a quarter of an inch high.
Since it’s made of a specialty ultralow-expansion glass, the mirror will resist flexing, which can happen to materials during temperature changes (like going from balmy Earth conditions to the deep freeze of space). This preserves Roman’s image quality, because if the primary mirror changed shape, it would distort the images from the telescope.
“We’re really proud of the amazing optical system we’ve delivered for the Roman mission alongside our partners at L3Harris,” said Josh Abel, lead Optical Telescope Assembly systems engineer at NASA Goddard. “Now that it’s assembled, aligned, and all shined up, we’re ready to go.”
Now, the Roman team is preparing to ship the observatory to the launch site at NASA’s Kennedy Space Center in Florida in the coming weeks. NASA expects the mission to begin returning incredible cosmic vistas within several months after launch.

This NASA Hubble Space Telescope image released on May 27, 2026, features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy’s low surface brightness makes it appear as a faint, starry swarm behind brighter foreground stars that are easily recognized by their diffraction spikes. Numerous red, orange, and beige dots are distant galaxies peppering the black background, many exhibiting distinct spiral structure.
The data in this image of ESO 490-017 was part of a Hubble observing program that looked at the movement of galaxies and galaxy clusters through space. Matter in the universe is distributed unevenly, and the gravitational influence of that matter drives the “cosmic flow” or movement of large-scale structures in the universe.

The focus of this NASA/ESA Hubble Space Telescope image is an active spiral galaxy on a journey lasting hundreds of millions of years. The galaxy Messier 88 (M88), also known as NGC 4501, is located about 63 million light-years away in the constellation Coma Berenices (Berenice’s Hair).
M88 is an active galaxy, which means that its center harbors a supermassive black hole that is snacking on gas and dust. Astronomers estimate the black hole is around 100 million times as massive as the Sun, and it appears to be powering outflows of gas from the galaxy’s center.
A population of old, reddish stars around the black hole give M88 its warmly glowing heart. Spreading out from the galaxy’s center are several tightly wound, symmetrical spiral arms, each outlined by sparkling pink and blue star clusters and knotted clouds of dust. We see M88 from an angle that makes it appear elongated, and its spiral arms delicately fan out before it.
M88 is a member of the Virgo Cluster, a collection of more than a thousand galaxies held together by gravity. As this massive galaxy group moves through space, the galaxies themselves are in constant motion as they orbit the cluster’s center of gravity. M88 itself is on a long and somewhat perilous cosmic journey that will bring it to the innermost reaches of the cluster.
As is the case with any epic journey, M88 will be fundamentally changed by its trek to the center of the Virgo Cluster, about two million light-years from where it is today. In 200–300 million years, M88 will make its closest approach to Messier 87, the massive elliptical galaxy that anchors the entire cluster. As it draws close to this gravitational behemoth, M88 will experience intense ram pressure stripping. Ram pressure stripping is a process through which a galaxy’s gas is swept away as it pushes through the ever-present gas between the galaxies in a cluster.
Researchers have already seen this process at work in M88. The galaxy’s swirling disk of gas is truncated and appears compressed on the leading edge of the galaxy, piling up gas and dust like snow before a plough. In fact, M88 appears to have considerably less cold gas — the raw fuel for star formation — than expected for a galaxy of its size, especially in its outer regions. This is a clear sign that M88 will be altered by its journey, which will affect its ability to form stars and alter the course of its evolution.
Astronomers observed M88 with Hubble as part of an observing program (#18103; PI: D. Thilker) dedicated to understanding the lives of spiral galaxies in crowded environments. This program uses Hubble’s Wide Field Camera 3, which can finely resolve individual star clusters and nebulae in galaxies tens of millions of light-years away. By studying galaxies on these scales, astronomers can understand how a journey through a cluster impacts a galaxy’s evolution and ability to form new stars.
