The splashdown of SpaceX’s Dragon Endurance spacecraft at 12:43 a.m. EDT (0443 GMT) Friday capped a 176-day mission for NASA commander Raja Chari, pilot Tom Marshburn, mission specialist Kayla Barron, and European Space Agency astronaut Matthias Maurer.
The mission, designated Crew-3, was the first flight of SpaceX’s Dragon Endurance spacecraft, the third of four human-rated Dragon capsules in SpaceX’s fleet.
“Thanks for letting us take Endurance on its shakedown cruise,” said Chari, a U.S. Air Force colonel and veteran fighter pilot. “Looking forward to watching many more flights of Endurance in the future. It was a great ride. Enjoyed working with the NASA and SpaceX teams. Thanks for getting us up to the space station and back safely.”
Chari, 44, made his first trip to space on the Dragon Endurance spacecraft. The Crew-3 mission was also the first spaceflight for Barron and Maurer, and the third for Marshburn, who has now flown on a space shuttle, a Russian Soyuz spacecraft, and a SpaceX Dragon vehicle.
The Crew-3 astronauts undocked from the space station at 1:20 a.m. EDT (0520 GMT) Thursday to begin a nearly 24-hour transit back to Earth. The Dragon Endurance spacecraft completed a series of burns to line up with the recovery zone off the coast of Tampa, Florida.
The capsule fired its Draco braking thrusters for nearly eight minutes to commit the spacecraft to re-entry. The Dragon Endurance spacecraft encountered the uppermost fringes of the atmosphere at 12:31 a.m. EDT (0431 GMT).

The build-up of super-hot plasma outside the capsule interrupted communications between the crew and mission control for about seven minutes, as expected. G-forces built up to several times the force of Earth’s gravity as friction from air molecules slowed the capsule from more than 17,000 mph to about 350 mph, when two drogue parachutes opened at an altitude of about 18,000 feet.
Less than a minute later, four main parachutes opened to slow the spacecraft to about 15 mph for splashdown in calm seas.
SpaceX’s recovery ship, named “Shannon” after NASA astronaut Shannon Walker, the first woman to fly on a Dragon spacecraft, pulled alongside the capsule and raised it from the ocean with a hydraulic lifting frame. Then SpaceX’s recovery team opened the Dragon hatch and helped the four astronauts out of their seats.
The astronauts were placed in recumbent seats as they got reacquainted to gravity for the first time in six months. All four crew members appeared happy and healthy, and NASA, ESA, and SpaceX medical personnel were aboard the ship for initial health checks on the astronauts.
The astronauts were expected to fly to shore on a helicopter, where a NASA jet was awaiting to carry the three NASA crew members back to their home base at the Johnson Space Center in Houston. An ESA airplane was scheduled to fly Maurer back o the European astronaut training center in Cologne, Germany.
Splashdown in the Gulf of Mexico confirmed at 12:43am EDT (0443 GMT).

The return of the Crew-3 astronauts Friday was the sixth launch or landing of a station crew since March 18, including two crew launches and two landings aboard SpaceX capsules.
Russia launched a team of three cosmonauts to the space station March 18 on a Soyuz spacecraft, followed by the undocking and landing of two cosmonauts and a NASA astronaut on a separate Soyuz mission March 30.
Then, on April 8, SpaceX launched four private astronauts on a Falcon 9 rocket and the Dragon Endeavour spacecraft on the first first fully commercial mission to the International Space Station. That flight, managed by a Houston company named Axiom Space, was commanded by retired NASA astronaut Mike López-Alegría.
Three Axiom customers, all wealthy businessmen, accompanied López-Alegría on the 17-day mission to perform experiments and public outreach events on the space station. The Axiom mission returned to Earth on April 25, and SpaceX launched the next long-duration crew mission for NASA — known as Crew-4 — from the Kennedy Space Center on April 27.
The Crew-4 astronauts, riding SpaceX’s Dragon Freedom capsule, docked at the station later the same day, joining the Russian cosmonauts and the Crew-3 astronauts on the outpost.
After a week-long handover, the Crew-3 astronauts packed their bags and prepared for their homecoming this week.
The Crew-3 mission launched Nov. 10 from Kennedy to begin the six-month expedition on the space station.
Marshburn, a 61-year-old medical doctor, ceremonially handed over command of the International Space Station crew to Russian cosmonaut Oleg Artemyev Wednesday, a few hours before departure.
Marshburn បាននិយាយថា "វាជាថ្ងៃគួរឱ្យចាប់អារម្មណ៍សម្រាប់ពួកយើង" ។ "យើងបានហោះហើរជុំវិញស្ថានីយ៍ ប្រមូលរូបថតនាទីចុងក្រោយរបស់យើង របស់របរក្នុងនាទីចុងក្រោយរបស់យើង ហើយត្រៀមខ្លួនដើម្បីត្រលប់មកផ្ទះវិញ ដូច្នេះថ្ងៃដ៏ជូរចត់សម្រាប់យើងទាំងអស់គ្នា។"
“I think, for all of us, it’s really hard to leave,” said Barron, U.S. Navy submarine officer before joining NASA’s astronaut corps. “We’re really looking forward to getting back to our families and our amazing support network on the ground.”
Maurer, a German materials scientist, said the highlights of his first space mission included the experiments, the launch, a spacewalk, and looking out the window to enjoy “the beauty of our planet Earth.”
Asked what he looked forward to upon return to Earth, Maurer replied he was excited to see family and friends, and enjoying the outdoors.
The Crew-3 mission was SpaceX’s third operational crew rotation flight to the space station for NASA. The crew was on-board the research outpost as diplomatic relations between the United States and Russia, the two most significant partners on the station, frayed in the aftermath of the Russian military invasion of Ukraine.

ប៉ុន្តែការងារនៅលើស្ថានីយ៍អវកាសបានបន្តដោយគ្មានការរំខាន។ ស្ថានីយ៍នេះតម្រូវឱ្យមានការរួមចំណែកសំខាន់ៗពីផ្នែកអាមេរិក និងរុស្ស៊ី ដើម្បីរក្សាប្រតិបត្តិការ។
Marshburn បាននិយាយថា "ខ្ញុំគិតថាកេរ្តិ៍ដំណែលយូរអង្វែងនៃស្ថានីយ៍អវកាសទំនងជាកិច្ចសហប្រតិបត្តិការអន្តរជាតិ និងជាកន្លែងសន្តិភាព" លោក Marshburn បាននិយាយថា គាត់បានប្រគល់បញ្ជាទៅ Artemyev ហើយ។ “ Oleg អ្នកគឺជាអវកាសយានិកខ្លាំង និងមានបទពិសោធន៍។ ខ្ញុំដឹងថាយើងនឹងចាកចេញពីស្ថានីយអវកាសដោយដៃល្អជាមួយអ្នក”។
Artemyev បានមកដល់ស្ថានីយ៍កាលពីខែមីនាជាមួយនឹងនាវិកអវកាសយានិករុស្ស៊ីពីរនាក់គឺ Sergey Korsakov និង Denis Matveev ។
Artemyev បានប្រាប់អវកាសយានិក Crew-3 ថា "យើងមានពេលខ្លី (រួមគ្នា) ... ហើយឥឡូវនេះយើងជាបងប្អូននឹងគ្នា" ។ “អ្វីដែលសំខាន់សម្រាប់ខ្ញុំ សម្រាប់លោក Sergey និងសម្រាប់ Denis គឺគ្រួសាររបស់យើង កូនៗរបស់យើង សន្តិភាពរវាងប្រទេសរបស់យើង និងមិត្តភាពរបស់យើង។ សូមអរគុណសម្រាប់មិត្តភាពរបស់អ្នក។"
In a press conference last month, Marshburn said he was looking forward to a hot bath after arriving back on Earth.
គាត់បាននិយាយថា "ខ្ញុំនឹកភពផែនដីរបស់យើង" ។ “ខ្ញុំនឹកឃើញថាត្រូវបានកប់ក្រោមពពក ហើយមានអារម្មណ៍ថាមានភ្លៀងធ្លាក់មកពីលើ ហើយមានអារម្មណ៍ថាចុងជើងខ្ញុំនៅក្នុងខ្សាច់ ស្មៅ”។
ចំណុចលេចធ្លោមួយនៃបេសកកម្មសម្រាប់ Marshburn ដែលជាវេជ្ជបណ្ឌិតផ្នែកវេជ្ជសាស្រ្ត និងជាអតីតគ្រូពេទ្យវះកាត់ជើងហោះហើររបស់ NASA កំពុងមើលបទពិសោធន៍អវកាសយានិករួមរបស់គាត់ក្នុងការហោះហើរអវកាសជាលើកដំបូង។

Marshburn បានបន្ថែមថា ជីវិតនៅលើស្ថានីយ៍អវកាសមិនត្រូវបានប៉ះពាល់ដោយផ្ទាល់ពីទំនាក់ទំនងដ៏តឹងតែងរវាងរុស្ស៊ី និងប្រទេសលោកខាងលិចនៅលើផែនដីនោះទេ។
Marshburn បាននិយាយថា៖ «វាជាទំនាក់ទំនងដ៏ស្និទ្ធស្នាល និងស្និទ្ធស្នាលបំផុតជាមួយគ្នានៅទីនេះ។ "យើងពិតជាត្រូវការគ្នាទៅវិញទៅមកសម្រាប់ការរស់រានមានជីវិតរបស់យើង។ វាជាបរិយាកាសដ៏គ្រោះថ្នាក់ ដូច្នេះយើងគ្រាន់តែទៅជាមួយការបណ្តុះបណ្តាលរបស់យើង យើងទៅជាមួយការទទួលស្គាល់ថាយើងទាំងអស់គ្នានៅទីនេះសម្រាប់គោលបំណងដូចគ្នា ដើម្បីរុករក និងរក្សាស្ថានីយ៍អវកាសនេះរក្សា និងបន្តអនុវត្តវិទ្យាសាស្ត្រនៅក្នុងមន្ទីរពិសោធន៍របស់យើង។
Marshburn បាននិយាយនៅក្នុងការឆ្លើយតបទៅនឹងសំណួរពី Spaceflight Now ថា "ដូច្នេះថាមវន្តមិនផ្លាស់ប្តូរទេ" ។ "យើងមានប្រវត្តិប្រហែល 40 ឆ្នាំនៃការធ្វើការជាមួយជនជាតិរុស្សី (ក្នុងលំហ) ហើយវាគឺខ្លាំងណាស់នៅក្នុងការងារនិងលេងនៅទីនេះ" ។
