On Monday, NASA and Boeing provided an update on the company’s Starliner spacecraft, including adding additional crew missions and certifying a new rocket for crew transportation to low Earth orbit.

“We are living through the most exciting era of space exploration since Apollo,” said NASA Administrator Jared Isaacman. “As this domain continues to open, there will be growing demand for launch vehicles, transfer stages, landers, and, of course, spacecraft that carry astronauts. NASA has been committed to having multiple crew transportation options since the beginning of the Commercial Crew Program. We have worked closely with Boeing to address the issues identified on previous Starliner flights, and we intend to see this vehicle return to flight in support of the International Space Station and future commercial destinations.”

The agency intends to exercise options for a fifth and sixth flight to and from the space station using Starliner, and will work with Boeing and United Launch Alliance to certify the Vulcan rocket for use after the Atlas V rocket’s final flight.

“We are starting with an uncrewed Starliner-1 mission to the International Space Station to validate the improvements made to the spacecraft and gather the flight data we need,” said Isaacman. “From there, we will use what we learn, continue implementing the corrective actions identified by our Program Investigation Team, and complete the testing and certification required for crewed flight. Our current plan is to return astronauts on Starliner-2 by 2028.”

NASA’s commercial crew efforts aim to preserve a U.S. crew transportation capability for ensuring continued access to space. The work is challenging, however, it is essential for responsibly concluding space station operations, transitioning to commercial space stations, and expanding commercial access.

In February, NASA released findings from the agency’s Program Investigation Team outlining the programmatic and technical issues resulting in an uncrewed return of the Starliner during its first crewed flight in 2024. In total, the investigation identified 61 recommendations to NASA to ensure that future missions meet the high standards required for human spaceflight.

The report specifically identified issues with Starliner’s service module reaction control thrusters operating outside of their engineering qualification, which resulted in the loss of control experienced during its Crew Flight Test. Through significant ground testing and analysis, NASA and Boeing learned the service module thruster performance issues resulted from a combination of factors, including the thermal environment and features inherent in its design.

Based on the findings, Boeing has made thermal modifications to the spacecraft’s service module which NASA will evaluate for improved performance on Starliner-1. NASA and Boeing also have jointly decided to implement an additional thruster valve design modification in support of spacecraft certification and future crewed flights.

The uncrewed Starliner-1 has the potential to fly in December of this year or January 2027. It will serve as an engineering evaluation mission to verify improved thermal environments, obtain necessary performance data for system qualification, and identify residual risk ahead of crewed missions.

“Starliner’s next flight is a critical step on the path to achieving full system certification and ensuring a sustained human presence in low Earth orbit,” said Dana Weigel, manager of NASA’s Low Earth Orbit Program. “With the safety of our space station crew and the public as our highest priority, we will test Starliner’s propulsion system through targeted demonstration objectives and disciplined operational controls. These steps are essential to validating Starliner’s thermal performance which is a key element for the certification.”

Following the flight, NASA and Boeing will complete the service module thruster valve design modification, which is focused on addressing poppet seal extrusion and its adverse effects on thruster performance. Boeing also will implement other improvements across the spacecraft including installation of new crew module thrusters, batteries, and minor modifications to the parachute system for increased performance and reliability in support of system certification.

NASA Armstrong Celebrates 80 Years of Flight Innovation

2026-09-28 19:20

On Sept. 30, 1946, five National Advisory Committee of Aeronautics (NACA) engineers arrived at Muroc Army Airfield in California’s high desert to achieve supersonic flight for the first time. In less than two years, NACA flew the X-1 aircraft faster than the speed of sound, marking an important milestone in aviation history.

Fast forward 80 years, and that former NACA outpost is now NASA’s Armstrong Flight Research Center in Edwards, California, flying the X-59 supersonic X-plane in the same skies to demonstrate that supersonic flight doesn’t have to come with a boom.

Over Armstrong’s 80-year history, the center has supported milestone missions ranging from space shuttle landings to SR-71 flights, shaping the evolution of science, aeronautics, and space research.

This Southern California NASA center is poised to lead the next era of aeronautics and human spaceflight, advancing technologies that will define the future of flight.

Fast facts

NASA Administrator Jared Isaacman recently named Armstrong as the agency’s Center of Excellence for Flight Test and Aircraft Operations, recognizing the center’s unmatched rigor in executing unique missions only NASA can fly.
To support NASA’s Artemis missions and return to the Moon, Armstrong uses research aircraft such as a 737 for astronaut suit testing, the G-III for Artemis II heat-shield data collection, and an F/A-18 aircraft that tested the autopilot for the SLS (Space Launch System) rocket.
NASA’s aeronautics centerpiece, the X-59, is undergoing rigorous testing and a series of flights at Armstrong to prepare for upcoming quiet supersonic demonstrations over U.S. communities.
NASA Armstrong has transformed commercial and military aviation — from early supersonic flight research to digital fly-by-wire — and continues working with other government agencies, industry, and academia to make flying safer, more autonomous, and more efficient.
The center plays a vital role in global science by flying aircraft like the ER-2, C-20A, and Gulfstream G-III/IV/V to collect critical data on wildfires, glacier melt, pollution, minerals, and more.

Behind these achievements are the engineers, pilots, technicians, and mission support teams who continue to push the boundaries of what’s possible.

NASA Highlights Lessons Learned From Swift Boost Mission

NASA Highlights Lessons Learned From Swift Boost Mission

A commercial mission to boost NASA’s Neil Gehrels Swift Observatory concluded without raising the spacecraft’s orbit, but the agency and industry vendor Katalyst Space have gained valuable experience that will benefit future in-space servicing programs.

“From the beginning, this was a high-risk, high-reward mission,” said Shawn Domagal-Goldman, Astrophysics Division director at NASA Headquarters in Washington. “Without intervention, Swift was going to re-enter the atmosphere by year’s end. And while we’ll be sad to see Swift’s mission come to a close, we knew this boost effort would be valuable to the agency on multiple levels — advancing U.S. spacecraft servicing technology, challenging us to meet unprecedented mission timelines, and testing how we operate satellites to extend their time in low Earth orbit. We’re very proud of how quickly this team got so far, and we’re capturing lessons learned to ensure we’re ready to go even farther.”

Swift, which launched in November 2004, was designed to study gamma-ray bursts, the most powerful explosions in the cosmos.

Over the last two decades, the observatory has revolutionized our understanding of how the universe works, from studying comets and asteroids in our own solar system and various types of cosmic explosions to flares from black holes in distant galaxies.

All spacecraft in low Earth orbit experience drag from our planet’s atmosphere. If they don’t have propulsion systems, this drag gradually reduces their altitudes. A period of increased solar activity magnified this effect on Swift.

After deciding to investigate the potential for a boost attempt, NASA had only a few months to issue a call for proposals through its Center of Excellence for Collaborative Engineering and fund design concept studies through the agency’s Small Business Innovation Research program.

In September 2025, NASA contracted Katalyst, based in Flagstaff, Arizona, to attempt the mission. The company had around one year to design, build, test, and launch a satellite that would then meet, grab, and lift Swift.

The LINK spacecraft took off from Kwajalein Atoll in the Republic of the Marshall Islands in July aboard a Northrop Grumman Pegasus XL rocket. Katalyst selected the Pegasus as the best launch option for reaching the observatory on the mission’s condensed timeline, based on the mission’s orbital and programmatic needs.

After successfully reaching space and performing initial spacecraft checkouts, LINK began experiencing intermittent communications losses and developed issues with its orientation control.

Following a period of around-the-clock troubleshooting from both teams, NASA and Katalyst agreed to scale back the mission. LINK would no longer attempt to grab or boost Swift but instead attempt to perform a series of technology demonstrations that would advance the capabilities of the U.S. commercial servicing industry.

These included exercising the spacecraft’s xenon-powered propulsion system and three robotic arms, which were designed to provide flexibility regarding where LINK could safely grapple Swift. NASA formally concluded the agency’s involvement in LINK’s mission on Sept. 3. The spacecraft re-entered the atmosphere on Sept. 25.

“LINK was built to take on a problem that did not have an easy solution,” said Ghonhee Lee, CEO of Katalyst Space. “This was an ambitious mission on an aggressive timeline. While we did not accomplish every objective we set out to achieve, in less than a year we went from mission concept to launching and operating the first commercial space robot. This is a foundation we can build on.”

Science missions like Swift take years to develop and then operate in orbit for decades. For the Swift boost, however, the most important factor was the timeline. All decision-making and risk acceptance hinged on predictions showing the observatory sinking to the point of no return — an altitude of around 185 miles (300 kilometers) — in fall 2026. As such, the boost mission required a new form of agile project management for NASA.

Swift team members in SSMO (Space Science Mission Operations) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, worked with Katalyst to develop milestones and approval processes that gave the mission the best chance of success while being flexible enough to move quickly toward launch.

Both groups received valuable input and feedback from NASA’s Engineering and Safety Center when tackling questions and issues that arose during integration and testing.

“Katalyst was committed to leveraging NASA’s deep experience to give themselves the best possible chance of successfully achieving the unprecedented challenge we gave them,” said Russell Carpenter, project manager in SSMO at NASA Goddard “Missions like these, where public-private teams work tenaciously to overcome obstacles, are an inspiration to the world, reminding us that striving for the near impossible brings out what is exceptional in all of us.”

Once all the air was pumped out of the 27-foot-diameter chamber, the team practiced firing the satellite’s ion thrusters and operated one of the robotic arms while they cycled through space-like hot and cold temperatures.

While teams at NASA and Katalyst were racing to get LINK ready on the ground, flight controllers in Swift’s Mission Operations Center, located at Penn State in University Park in Pennsylvania, were trying to keep Swift above the critical altitude for as long as possible. Below it, any boost attempt would become increasingly difficult.

During normal operations, the Penn State team sends a plan to Swift that tells the observatory which cosmic objects and events to observe each day.

In December 2025, however, the controllers started swapping around 25% of these science targets for points on the sky that would minimize drag when Swift was trained on them. By February, the team had switched over to this approach entirely.

“Even though Swift was not executing pointed science observations from mid-February to late August, we nonetheless continued Penn State’s history of innovative space research and operations, pioneering new methods to minimize drag experienced by the spacecraft,” said John Nousek, the mission director and professor of astronomy and astrophysics in the university’s Eberly College of Science. “These changes bought valuable time for the boost mission and can be carried forward for future NASA missions.”

The team also couldn’t point too close to Earth, the Moon, or the Sun, since the brightness of all three could overheat and damage the observatory’s instruments. Pointing Swift in the most streamlined position also tilted it too close to the atmosphere, where particles could collide with the telescopes and affect future observations. The team struck a balance that managed to maintain Swift’s altitude above the critical threshold for several months.

“We’re grateful to all our collaborators for the incredible amount of time and dedication they’ve put into the boost mission,” said S. Bradley Cenko, Swift’s principal investigator at NASA Goddard. “When Neil Gehrels, Swift’s namesake, designed the observatory, nothing like it had ever launched. He would have celebrated that this boost effort was part of Swift’s legacy, that it allowed NASA to try something new and daring even though the outcome wasn’t guaranteed. That’s how we explore the universe — as a team, learning from each other, constantly pushing forward.”

NASA Celebrates as Artemis Accords Surpasses 75 Signatories

2026-09-28 16:26

Marking a significant expansion in the number of signatories to the Artemis Accords, NASA welcomed Albania, Croatia, Côte d’Ivoire, and San Marino, bringing total participation to 76 countries.

“Our momentum reflects a growing commitment to peaceful, responsible exploration and a shared understanding that the future in space will be shaped by those willing to lead,” said NASA Administrator Jared Isaacman. “Nearly one-third of all signatories have joined since the start of President Trump’s second term. As the President directs NASA to return Americans to the lunar surface and lay the groundwork for Mars, we are strengthening a coalition of partners who share our values and are ready to help shape the future of exploration.”

The recent surge in growth reflects one of the most rapid expansions of international cooperation in civil space history. Nearly 40% of the world’s nations are now collaborating with NASA to build a transparent, peaceful, responsible, and safe approach to space exploration. Nearly two-thirds of countries that signed the foundational 1967 Outer Space Treaty also have signed the Artemis Accords.

What began as an informal coalition of a small group of countries has developed into a large, structured community guided by the Signatories Group Method of Operations, adopted in 2024. Under this framework, the group meets twice annually, once at a technical workshop and once at a Principals’ Meeting during the International Astronautical Congress (IAC). Virtual sessions are added throughout the year to support implementation.

As a result, participating countries have advanced agreed-upon recommendations on noninterference, interoperability, scientific data sharing, and registration practices.

Two major workshops this year further strengthened technical alignment. Signatories reviewed their planned lunar landings and orbital missions and took part in hands‑on sessions focused on open science and practical tools for sharing lunar data. Experts from dozens of countries worked through real-world examples of how to make mission information easier to find, use, and share, from releasing lunar science data to adopting common standards that reduce interference between missions.

This year’s Artemis Accords Principals’ Meeting at IAC in Antalya, Türkiye, beginning Monday, Oct. 5, will be co-chaired by NASA Deputy Administrator Matt Anderson and Major General Roberto Melgar Sheen, director of the Peruvian Space Agency (CONIDA). The meeting will examine ways to support emerging space nations and disseminate lunar debris‑mitigation recommendations.

NASA continues to put the principles of the Artemis Accords into practice. With the creation of the Moon Base, NASA has invited every Artemis Accords signatory to participate in our return to the Moon through scientific payloads, technology demonstrations, CubeSats, and other capabilities.

The United States, led by NASA and the U.S. Department of State, and seven other nations launched the Artemis Accords in 2020 to guide growing global interest in lunar activity. The accords established the first set of practical principles to enhance safety and coordination as nations explore the Moon, Mars, and beyond. Signatories commit to:

Explore peaceably and transparently
Render aid to those in need
Enable access to scientific data
Ensure activities do not interfere with others
Preserve historically significant sites and artifacts by developing best practices

More nations are expected to join the Artemis Accords in the months and years ahead as NASA continues working with partners worldwide to secure a safe, peaceful, and prosperous future in space.

Editor’s Note: This advisory was updated on Sept. 28, 2026, with ticketing information for the public.

The four astronauts of NASA’s Artemis II mission will participate in an event hosted by industry and community partners at the University of Houston to discuss their mission around the Moon aboard the Orion spacecraft. It will be the first event in Houston for the public following their lunar mission earlier this year and marks the conclusion of their post-flight campaign.

Astronauts Reid Wiseman, Victor Glover, and Christina Koch of NASA and CSA (Canadian Space Agency) astronaut Jeremy Hansen will share highlights from their mission at 7 p.m. CDT Wednesday, Sept. 30, during the free, public event at University of Houston’s Fertitta Center. Additionally, the National Aeronautic Association will recognize the crew for surpassing the record for human spaceflight’s farthest distance traveled, previously set by the Apollo 13 mission in 1970.

Media are invited to attend a brief question and answer session with the Artemis II crew at 5:45 p.m. prior to the public presentation. Media interested in attending must RSVP no later than 12 p.m. on Sept. 30 to Kenna Pell at: kenna.m.pell@nasa.gov.

A limited number of tickets to attend the event at no charge are available to the public online. Media are not required to secure a ticket before RSVPing to the event.

NASA’s historic Artemis II mission launched April 1 and splashed down in the Pacific Ocean on April 10. The crew members were the first astronauts to launch on the agency’s SLS (Space Launch System) rocket, flying aboard NASA’s Orion spacecraft. During their record-setting mission, the astronauts traveled 252,756 miles from Earth, farther than any humans have traveled before.

As part of the Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.
