NASA and SpaceX reschedule Dragon capsule departure from ISS to May 23
NASA
and
SpaceX
have officially rescheduled the undocking of the Dragon cargo capsule from the
International Space Station
(
ISS
) to May 23, after poor weather conditions at the
splashdown
site prompted a delay. Originally planned for May 22, the departure is now set for 12:05 p.m. EDT on Friday. The capsule, part of the
CRS-32 mission
, has been docked at the station since April 22 and is scheduled to return to Earth carrying scientific experiments and supplies. NASA will livestream the undocking event on its NASA+ platform, beginning at 11:45 a.m. EDT.
What is CRS-32 mission of SpaceX and NASA
The CRS-32 mission is the 32nd cargo delivery flight operated by SpaceX under NASA's Commercial Resupply Services program. Launched on April 21 from Kennedy Space Center in Florida aboard a Falcon 9 rocket, the
Dragon capsule
arrived at the ISS a day later. It delivered approximately 6,700 pounds of food, hardware, and scientific research material.

The departure was initially scheduled for May 22, but unfavorable weather at the Pacific Ocean splashdown zone forced the teams to postpone the undocking. Safety protocols require suitable sea conditions to ensure a smooth recovery of the spacecraft and its cargo. SpaceX and NASA are now targeting May 23, anticipating improved weather conditions for re-entry and splashdown operations.
Return cargo and experiments
The Dragon capsule will bring back a variety of scientific experiments, including samples from NASA's MISSE-20 materials study, which evaluates how different materials withstand space conditions. Also on board are the Astrobee robotic assistant, technology demonstration hardware such as the REACCH system, and other items no longer needed on the station. Some non-recyclable waste will also be disposed of on re-entry.
Undocking and splashdown timeline
If undocking proceeds as planned at 12:05 p.m. EDT on May 23, the Dragon capsule will slowly maneuver away from the station. It will conduct a series of orbital adjustments before beginning its deorbit burn. The capsule is expected to splash down off the California coast early Sunday morning, May 25. Although NASA will broadcast the undocking live, the splashdown itself will not be webcast.
Unique capabilities of Dragon
SpaceX's Dragon is currently the only operational cargo spacecraft capable of returning significant payloads safely to Earth. Other supply vehicles like Northrop Grumman's Cygnus and Russia's Progress are designed to burn up during reentry. This return capability makes Dragon essential for transporting completed experiments, station hardware, and other valuable cargo back to Earth.
As part of an ongoing partnership between NASA and SpaceX, Dragon missions like CRS-32 support continuous research and resupply operations aboard the ISS. With future flights already scheduled, including both cargo and crewed missions, the success of each Dragon capsule recovery helps ensure reliability and continuity in space logistics.

1st Picture Of Dragon Spacecraft That Will Take Astronaut Shubhanshu Shukla To Space
The first picture of the Dragon spacecraft, set to carry Indian astronaut Shubhanshu Shukla on a historic mission to the International Space Station (ISS), have been made public. The spacecraft is built to transport four astronauts, who will return to Earth at the end of their mission. It has reached the hangar at pad 39A in Florida, where it is preparing for its first space flight. Astronauts from the United States, India, Poland, and Hungary will go on this thrilling adventure as part of a private mission by Axiom Space. SpaceX shared the first image of the rocket in a post on X and wrote, "Dragon arrives at the hangar at pad 39A in Florida ahead of its first flight. Falcon 9 is targeted to launch Dragon and @Axiom_Space's Ax-4 crew to the @Space_Station. Next Tuesday, June 10." Dragon arrives at the hangar at pad 39A in Florida ahead of its first flight. Falcon 9 is targeted to launch Dragon and @Axiom_Space 's Ax-4 crew to the @Space_Station next Tuesday, June 10 — SpaceX (@SpaceX) June 5, 2025 The earlier liftoff was scheduled for June 8, 2025, at 6.41 pm but was postponed by two days to June 10. While no reason was officially announced for the delay, a source said it happened to "account for the weather during vehicle transportation and completing final processing of the vehicle ahead of launch". Group Captain Shukla is scheduled to pilot the Axiom-4 mission, a private astronaut mission that will launch aboard a SpaceX Dragon capsule on a SpaceX Falcon 9 rocket. In a statement, Axiom Space said, "The launch of the Axiom-4 crew will take place from Launch Complex 39A at NASA's Kennedy Space Centre in Florida". His space voyage is a historic one for India, coming forty years after Rakesh Sharma's iconic spaceflight on Russia's Soyuz spacecraft in 1984. It is particularly significant as it will help India's space travel program and the Gaganyaan mission. Slawosz Uznanski-Wisniewski from Poland, Tibor Kapu from Hungary, and Peggy Whitson, a former NASA astronaut and mission commander, will accompany Group Captain Shukla on this space trip. The astronauts will perform scientific, outreach and commercial activities on board the orbiting laboratory for up to 14 days after docking.

Earth shook every 90 seconds for 9 days in 2023; scientists finally reveal the shocking reason
Earth shook every 90 seconds for 9 days in 2023 In September 2023, seismic monitoring stations around the world began to register an eerie, rhythmic signal. Every 90 seconds, the Earth appeared to pulse—faintly but persistently. The phenomenon lasted for nine days and returned a month later, leaving scientists puzzled. There was no accompanying earthquake, volcanic eruption, or explosion to explain the tremors. The source of the mystery was traced to the remote Dickson Fjord in East Greenland. At the time, theories ranged from submarine volcanic activity to secret military tests. Now, almost two years later, researchers from the University of Oxford have offered the first concrete explanation using next-generation satellite and machine learning technologies. What they uncovered reveals not only the cause of the pulses but also a broader warning about the climate crisis unfolding silently in the world's most remote corners. The Earth shook without warning: 2023's 90-second Arctic pulse For nine consecutive days in September 2023, and again in October, seismic stations recorded signals repeating every 90 seconds. These pulses were subtle—far weaker than earthquakes—but unusual because of their precise regularity and global reach. The signals came from the Arctic, specifically from the Dickson Fjord in East Greenland. The incident baffled geophysicists and prompted international investigations. With no explosion, tectonic activity, or obvious surface disturbance detected, the mystery deepened. Seiches vs. Tsunamis: Understanding the difference Initially, some suspected a tsunami might be responsible. But experts soon distinguished the phenomenon as a seiche—a lesser-known but powerful water oscillation. Tsunami: Caused by abrupt displacement of water due to earthquakes, volcanic activity, or landslides. It travels as a single massive wave. Seiche : Occurs when water in an enclosed space like a lake or fjord repeatedly sloshes back and forth, creating standing waves. These are often triggered by landslides, strong winds, or seismic activity. In this case, scientists confirmed the Dickson Fjord had experienced seiches—giant oscillating waves that created rhythmic seismic pulses without causing surface devastation. What caused the Greenland Seiches Researchers now confirm that the seismic pulses were the result of two massive glacier-induced rock and ice avalanches. These avalanches thundered into Dickson Fjord, displacing enormous volumes of water and generating tsunami-like waves with an initial height of up to 7.9 meters. Due to the fjord's narrow and enclosed topography, the waves couldn't escape and instead bounced back and forth like water in a bathtub. These oscillations—seiches—persisted for days, producing low-frequency seismic energy detectable across continents. How NASA's SWOT satellite uncovered Greenland's hidden waves The game-changer was data from NASA and the French space agency CNES's Surface Water and Ocean Topography (SWOT) satellite, launched in December 2022. The satellite's Ka-band Radar Interferometer (KaRIn) allowed researchers to scan a 30-mile-wide swath of the ocean surface in high resolution—something no previous satellite system could do. Oxford scientists used SWOT to map subtle elevation shifts in the fjord's surface after the event. They observed slopes of up to two meters across the channel that reversed direction over time—clear signatures of standing wave motion. Supporting evidence: Machine learning and seismic models To fill in gaps in satellite data, scientists employed: Machine learning to reconstruct wave behavior over time. Crustal deformation data from sensors thousands of kilometers away. Weather pattern analysis, ruling out wind and tides as causes. This multidisciplinary approach confirmed that the rhythmic seismic pulses came from seiche-driven energy trapped in the fjord. Climate change's fingerprints are all over the event The most alarming takeaway from the study is the role of climate change. Warming Arctic temperatures are rapidly melting Greenland's glaciers, weakening adjacent slopes and increasing the frequency of catastrophic landslides. As lead researcher Thomas Monahan stated: 'Climate change is giving rise to new, unseen extremes. These changes are happening fastest in remote areas like the Arctic, where our ability to monitor them has historically been limited.' The study highlights how climate-driven geological events can have global seismic effects—often silently and without warning. Why it matters: A new era of Earth monitoring The incident and its resolution mark a turning point in Earth observation. Co-author Professor Thomas Adcock emphasized: 'This is a perfect example of how next-generation satellite data and advanced modeling can resolve phenomena that have long been mysteries. We're entering an era where we can better track tsunamis, storm surges, and even rogue waves.' Moreover, a Danish military vessel patrolling the fjord three days after the first pulse observed nothing out of the ordinary—underscoring how even massive events can leave little trace without advanced monitoring systems.
