NASA and Boeing welcomed Starliner back to Earth following the uncrewed spacecraft’s successful landing at 10:01 p.m. MDT Sept. 6, 2024, at the White Sands Space Harbor in New Mexico. Credit: NASA NASA and Boeing safely returned the uncrewed Starliner spacecraft following its landing at 10:01 p.m. MDT Sept. 6 at White Sands Space Harbor in New Mexico, concluding a three-month flight test to the International Space Station.
“I am extremely proud of the work our collective team put into this entire flight test, and we are pleased to see Starliner’s safe return,” said Ken Bowersox, associate administrator, Space Operations Mission Directorate at NASA Headquarters in Washington. “Even though it was necessary to return the spacecraft uncrewed, NASA and Boeing learned an incredible amount about Starliner in the most extreme environment possible. NASA looks forward to our continued work with the Boeing team to proceed toward certification of Starliner for crew rotation missions to the space station.”
The flight on June 5 was the first time astronauts launched aboard the Starliner. It was the third orbital flight of the spacecraft, and its second return from the orbiting laboratory. Starliner now will ship to NASA’s Kennedy Space Center in Florida for inspection and processing.
NASA’s Commercial Crew Program requires a spacecraft to fly a crewed test flight to prove the system is ready for regular flights to and from the orbiting laboratory. Following Starliner’s return, the agency will review all mission-related data.
“We are excited to have Starliner home safely. This was an important test flight for NASA in setting us up for future missions on the Starliner system,” said Steve Stich, manager of NASA’s Commercial Crew Program. “There was a lot of valuable learning that will enable our long-term success. I want to commend the entire team for their hard work and dedication over the past three months.”
NASA astronauts Butch Wilmore and Suni Williams launched on June 5 aboard Starliner for the agency’s Boeing Crewed Flight Test from Cape Canaveral Space Force Station in Florida. On June 6, as Starliner approached the space station, NASA and Boeing identified helium leaks and experienced issues with the spacecraft’s reaction control thrusters. Following weeks of in-space and ground testing, technical interchange meetings, and agency reviews, NASA made the decision to prioritize safety and return Starliner without its crew. Wilmore and Williams will continue their work aboard station as part of the Expedition 71/72 crew, returning in February 2025 with the agency’s SpaceX Crew-9 mission.
The crew flight test is part of NASA’s Commercial Crew Program. The goal of NASA’s Commercial Crew Program is safe, reliable, and cost-effective transportation to and from the International Space Station and low Earth orbit. This already is providing additional research time and has increased the opportunity for discovery aboard humanity’s microgravity testbed, including helping NASA prepare for human exploration of the Moon and Mars.

NASA Summer Camp Inspires Future Climate Leaders
From July 15-19, 2024, the Coastal Equity and Resilience Hub at the Georgia Institute of Technology collaborated with the University of Georgia (UGA) Marine Extension and Georgia Sea Grant to host a week-long NASA Sea Level Changemakers Summer Camp. The camp introduced 14 rising 7th-8th graders to how coastal areas are changing due to sea level rise. Set at the UGA Marine Education Center and Aquarium on Skidaway Island, the camp offered students hands-on activities and outdoor educational experiences, where they analyzed real data collected by NASA scientists and learned about community adaptations to flooding. Students interacted with experts from NASA’s Jet Propulsion Laboratory, UGA, and Georgia Tech, gaining insights into satellite observations, green infrastructure, environmental sensors, and careers related to sea level rise. The camp also included a visit to the Pin Point Heritage Museum, where students engaged with leaders from the historic Gullah Geechee community of Pin Point. The camp concluded with a boat trip to Wassaw Island, where students observed the effects of sea level rise on an undeveloped barrier island and compared these observations with earlier findings from urban environments. Funding from the NASA’s Science Activation Program and its Sea Level Education, Awareness, and Literacy (SEAL) team ensured that the camp was accessible to all students, eliminating financial barriers for groups traditionally underrepresented in STEM education.
“This investment from NASA has provided an amazing opportunity for youth in coastal Georgia to utilize NASA data and resources on a critical issue affecting their communities,” said Jill Gambill, executive director of the Coastal Equity and Resilience (CEAR) Hub at Georgia Tech. “They have more confidence now in their knowledge of sea level rise and potential solutions.”
The Sea Level Education, Awareness, and Literacy (SEAL) team is supported by NASA under cooperative agreement award number NNH21ZDA001N-SCIACT and is part of NASA’s Science Activation Portfolio.

NASA and Boeing teams work around Boeing’s Starliner spacecraft after it landed at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Boeing’s Orbital Flight Test-2.NASA/Bill Ingalls As NASA and Boeing prepare to return the company’s Starliner spacecraft uncrewed from the International Space Station to Earth, safety and mission success remain as top priorities for the teams. Mission managers will complete a series of operational and weather checks before the spacecraft undocks from the orbital complex.
The Starliner spacecraft is the first American capsule designed to touch down on land, supporting expedited astronaut and cargo recovery on future missions and to aid the company in spacecraft refurbishment. For Starliner missions, NASA and Boeing will use potential landing locations in the White Sands Missile Range, New Mexico; Willcox, Arizona; and Dugway Proving Ground, Utah. Edwards Air Force Base in California also is available as a contingency landing site.
Twenty-four hours before undocking, NASA analyzes weather predictions for the various landing sites. Winds at the selected landing site must be 6 mph (approximately 6 knots) or less when flying with crew, and approximately 13 mph (12 knots) or less when uncrewed. Ground temperatures must be warmer than 15 degrees Fahrenheit, and the cloud ceiling must be at least 1,000 feet. One nautical mile of visibility is required, and the area must be clear of precipitation, thunderstorms, and lightning within approximately a 22-mile (35-kilometer) radius.
When teams proceed with undocking, Starliner will complete a series of departure burns, allowing it to reach its landing site in as little as six hours. A final weather check also occurs before the spacecraft’s deorbit burn. Winds must be at or below 10 mph (9 knots). If winds exceed these limits, teams will waive the deorbit burn, and Starliner will target another landing attempt between 24 and 31 hours later.
Once clear to proceed, Starliner executes its deorbit burn, which lasts approximately 60 seconds, slowing it down enough to re-enter Earth’s atmosphere and committing the spacecraft to its targeted site. Immediately after the deorbit burn, Starliner repositions for service module disposal, which will burn up during re-entry over the southern Pacific Ocean.
Following service module separation, the command module maneuvers into re-entry position. During re-entry, the capsule experiences plasma buildup – reaching temperatures up to 3,000 degrees Fahrenheit – that may interrupt communications with the spacecraft for approximately four minutes.
NASA and Boeing teams work around Boeing’s Starliner spacecraft after it landed at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Boeing’s Orbital Flight Test-2.NASA/Bill Ingalls Once Starliner re-enters Earth’s atmosphere, the forward heatshield – located on the top of the spacecraft – is jettisoned at 30,000 feet, exposing the two drogue and three main parachutes for deployment. The parachutes will continue to slow the spacecraft down as the base heatshield is jettisoned at 3,000 feet, allowing the six landing bags to inflate. At touchdown, the spacecraft is traveling at approximately 4 mph.
NASA and Boeing teams prepare for the landing of Boeing’s Starliner spacecraft at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Orbital Flight Test-2.NASA/Bill Ingalls The NASA and Boeing landing and recovery team is stationed at a holding zone near Starliner’s intended landing site. After landing, a series of five teams move in toward the spacecraft in a sequential order.
The first team to approach the spacecraft is the gold team, using equipment that “sniffs” the capsule for any hypergolic fuels that didn’t fully burn off before re-entry. They also cover the spacecraft’s thrusters. Once given the all-clear, the silver team moves in. This team electrically grounds and stabilizes Starliner before the green team approaches, supplying power and cooling to the crew module since the spacecraft is powered down.

The spacecraft is then transferred to Boeing facilities at NASA’s Kennedy Space Center in Florida for refurbishment ahead of its next flight.
NASA’s Commercial Crew Program is working with the American aerospace industry through a public-private partnership to launch astronauts on American rockets and spacecraft from American soil. The program’s goal is to provide safe, reliable, and cost-effective transportation on space station missions, which will allow for additional research time. The space station remains the springboard to NASA’s next great leap in space exploration, including future missions to the Moon and, eventually, to Mars.

NASA’s Hubble, MAVEN Help Solve the Mystery of Mars’ Escaping Water
NASA, ESA, STScI, John T. Clarke (Boston University); Processing: Joseph DePasquale (STScI) Mars was once a very wet planet as is evident in its surface geological features. Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest? Now, NASA’s Hubble Space Telescope and MAVEN (Mars Atmosphere and Volatile Evolution) missions are helping unlock that mystery.
“There are only two places water can go. It can freeze into the ground, or the water molecule can break into atoms, and the atoms can escape from the top of the atmosphere into space,” explained study leader John Clarke of the Center for Space Physics at Boston University in Massachusetts. “To understand how much water there was and what happened to it, we need to understand how the atoms escape into space.”
Clarke and his team combined data from Hubble and MAVEN to measure the number and current escape rate of the hydrogen atoms escaping into space. This information allowed them to extrapolate the escape rate backwards through time to understand the history of water on the Red Planet.
Escaping Hydrogen and “Heavy Hydrogen”
Water molecules in the Martian atmosphere are broken apart by sunlight into hydrogen and oxygen atoms. Specifically, the team measured hydrogen and deuterium, which is a hydrogen atom with a neutron in its nucleus. This neutron gives deuterium twice the mass of hydrogen. Because its mass is higher, deuterium escapes into space much more slowly than regular hydrogen.
Over time, as more hydrogen was lost than deuterium, the ratio of deuterium to hydrogen built up in the atmosphere. Measuring the ratio today gives scientists a clue to how much water was present during the warm, wet period on Mars. By studying how these atoms currently escape, they can understand the processes that determined the escape rates over the last four billion years and thereby extrapolate back in time.
Although most of the study’s data comes from the MAVEN spacecraft, MAVEN is not sensitive enough to see the deuterium emission at all times of the Martian year. Unlike the Earth, Mars swings far from the Sun in its elliptical orbit during the long Martian winter, and the deuterium emissions become faint. Clarke and his team needed the Hubble data to “fill in the blanks” and complete an annual cycle for three Martian years (each of which is 687 Earth days). Hubble also provided additional data going back to 1991 – prior to MAVEN’s arrival at Mars in 2014.
The combination of data between these missions provided the first holistic view of hydrogen atoms escaping Mars into space.
These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.
Reflected sunlight from Mars at these wavelengths shows scattering by atmospheric molecules and haze, while the polar ice caps and some surface features are also visible. Hubble and MAVEN showed that Martian atmospheric conditions change very quickly. When Mars is close to the Sun, water molecules rise very rapidly through the atmosphere, breaking apart and releasing atoms at high altitudes. NASA, ESA, STScI, John T. Clarke (Boston University); Processing: Joseph DePasquale (STScI)

A Dynamic and Turbulent Martian Atmosphere
“In recent years scientists have found that Mars has an annual cycle that is much more dynamic than people expected 10 or 15 years ago,” explained Clarke. “The whole atmosphere is very turbulent, heating up and cooling down on short timescales, even down to hours. The atmosphere expands and contracts as the brightness of the Sun at Mars varies by 40 percent over the course of a Martian year.”
The team discovered that the escape rates of hydrogen and deuterium change rapidly when Mars is close to the Sun. In the classical picture that scientists previously had, these atoms were thought to slowly diffuse upward through the atmosphere to a height where they could escape.
But that picture no longer accurately reflects the whole story, because now scientists know that atmospheric conditions change very quickly. When Mars is close to the Sun, the water molecules, which are the source of the hydrogen and deuterium, rise through the atmosphere very rapidly releasing atoms at high altitudes.
The second finding is that the changes in hydrogen and deuterium are so rapid that the atomic escape needs added energy to explain them. At the temperature of the upper atmosphere only a small fraction of the atoms have enough speed to escape the gravity of Mars. Faster (super-thermal) atoms are produced when something gives the atom a kick of extra energy. These events include collisions from solar wind protons entering the atmosphere or sunlight that drives chemical reactions in the upper atmosphere.

Studying the history of water on Mars is fundamental not only to understanding planets in our own solar system but also the evolution of Earth-size planets around other stars. Astronomers are finding more and more of these planets, but they’re difficult to study in detail. Mars, Earth and Venus all sit in or near our solar system’s habitable zone, the region around a star where liquid water could pool on a rocky planet; yet all three planets have dramatically different present-day conditions. Along with its sister planets, Mars can help scientists grasp the nature of far-flung worlds across our galaxy.
These results appear in the July 26 edition of Science Advances, published by the American Association for the Advancement of Science.
