Sunita Williams Returns to Earth: Indian-American astronaut Sunita Williams and her fellow astronaut Butch Wilmore have successfully returned to Earth after spending 9 months and 14 days aboard the International Space Station (ISS). Accompanying them were two more Crew-9 astronauts, Nick Hague from the United States and Alexander Gorbunov from Russia. Their spacecraft, the Dragon capsule, made a safe splashdown off the coast of Florida at 3:27 am IST on March 19.

Fiery Re-entry and Communication Blackout
The journey from the ISS to Earth was not without its challenges. As the Dragon capsule entered the Earth’s atmosphere, the spacecraft’s external temperature soared to a blistering 1650 degrees Celsius. This intense heat is a normal part of re-entry caused by the friction between the spacecraft and the Earth’s atmosphere.
During this phase, there was a 7-minute communication blackout, a common occurrence during atmospheric re-entry. The blackout is due to the formation of plasma around the spacecraft, which temporarily blocks radio signals. Despite this communication loss, the spacecraft continued its descent smoothly before finally splashing down in the waters off Florida.
17-Hour Journey From ISS to Earth
- Total Duration: The journey from the ISS to Earth took approximately 17 hours.
- Hatch Closure: The spacecraft’s hatch was closed at 8:35 am IST on March 18.
- Separation from ISS: The Dragon capsule separated from the ISS at 10:35 am IST, beginning its descent to Earth.
- Deorbit Burn: At 2:41 am IST on March 19, the spacecraft initiated its deorbit burn to slow down and re-enter the Earth’s atmosphere.
- Splashdown: After approximately 46 minutes, at 3:27 am IST, the capsule safely splashed down in the ocean off the coast of Florida, concluding the mission successfully.
Mission That Lasted Far Longer Than Planned
Sunita Williams and Butch Wilmore originally embarked on an 8-day joint mission called the ‘Crew Flight Test Mission,’ organized by Boeing and NASA. The primary objective of the mission was to test Boeing’s Starliner spacecraft’s ability to safely transport astronauts to the ISS and bring them back to Earth.
However, the mission’s duration extended drastically from 8 days to over 9 months due to a malfunction with the spacecraft’s thruster. The unexpected technical issue forced the crew to remain aboard the ISS, where they continued conducting research and various experiments.
Who Is Sunita Williams?
Sunita Williams, a celebrated Indian-American astronaut, has been a part of several space missions. Known for her resilience and dedication, her recent return has once again showcased her strength and professionalism as an astronaut.
Lex Fridman’s Interview with Sunita Williams
This remarkable mission comes just days after her interview with renowned AI researcher and podcaster Lex Fridman. Fridman, an expert in computer engineering and artificial intelligence, is known for his engaging discussions with influential personalities. His podcast has featured several world leaders and tech icons, including Elon Musk, Mark Zuckerberg, Donald Trump, and Sam Altman.
Fridman, who holds a PhD in Electrical and Computer Engineering, was born in Chkalovsk, Russia, before his family moved to Chicago, USA, following the collapse of the Soviet Union. His interest in artificial intelligence and human cognition has made him a respected voice in the AI community.
What’s Next for Sunita Williams and the Crew?
Following their return, Sunita Williams, Butch Wilmore, and the rest of the Crew-9 astronauts will undergo a thorough medical evaluation to ensure they are in good health after spending nearly a year in space. NASA and Boeing will also conduct extensive studies on the thruster malfunction that prolonged their mission.
