Indian astronaut Group Captain Shubhanshu Shukla, along with Commander Peggy Whitson, Slawosz 'Suave' Uznanski-Wisniewski, and Tibor Kapu, is preparing to return to Earth after an 18-day mission aboard the International Space Station (ISS) as part of the Axiom-4 (Ax-4) mission.
According to NASA, the crew began departure preparations with hatch closure at 2:00 pm IST on Monday (July 14).
By 2:25 pm IST, the crew was inside the SpaceX Dragon spacecraft, named 'Grace,' with the hatch closed.
STORY CONTINUES BELOW THIS AD
Undocking procedures are set to start at approximately 4:15 pm IST, with the actual undocking from the ISS's Harmony module expected at 4:35 pm IST (7:05 am EDT).
The spacecraft is scheduled to splash down off the California coast in the Pacific Ocean at around 3:00 pm IST (9:30 am GMT) on Tuesday (July 15), with a one-hour margin of flexibility due to weather and re-entry conditions, as noted by Union Minister for Science & Technology and Earth Sciences Dr. Jitendra Singh.
'These timings have a margin window of approximately 1 hour,' Indian Union Minister for Science & Technology and Earth Sciences Dr Jitendra Singh said.
What was Shukla's mission?
During his time on the ISS, Shukla conducted significant experiments, including a study on space microalgae to explore their potential for producing food, oxygen, and biofuels for long-duration space missions.
He performed centrifugation on cyanobacteria, comparing two strains to investigate how microgravity impacts their growth, cellular behaviour, and biochemical activity.
These experiments, among the 60+ conducted by the Ax-4 crew, could pave the way for advancements in space agriculture and life support systems.

Climate change is redrawing flash flood maps in India: IIT Study
NEW DELHI: A new study by IIT Gandhinagar has revealed a disturbing shift in India's flash flood geography, warning that climate change is driving the emergence of new flood-prone regions in areas once considered very safe. Published in the journal 'Natural Hazards', the study, titled "Drivers of Flash Floods in the Indian Subcontinental River Basins' finds that flash flood hotspots are expanding beyond traditionally vulnerable zones into drier and semi-arid regions. 'Flash floods are sudden inundations caused by extreme rainfall events. They typically occur within a very short time frame, usually within six hours, after heavy precipitation,' the researchers noted. 'Characterised by a rapid increase in water flow followed by a quick recession, flash floods are highly unpredictable and can be extremely destructive.' The study observed a marked rise in flash floods across semi-arid zones of western India, regions previously seen as low-risk from the risk if flash floods. It attributes this shift to an increase in sub-daily precipitation events and rising temperatures, which allow the atmosphere to retain more moisture and trigger intense rainfall. Even sub-basins earlier considered low in susceptibility are now showing significant increases in both precipitation and streamflow. The researchers compared data from 2001 to 2020 with a baseline of 1981–2000 and found a sharp rise in wet hours — a key driver of flash floods — across all Indian river basins not previously categorised as prone.

Is there a Solar Eclipse on August 2, 2025? Here's what astronomers and skygazers can watch out for
A solar eclipse takes place when the Moon moves between the Earth and the Sun, obstructing sunlight and casting a shadow over parts of the Earth. Tired of too many ads? Remove Ads No Solar Eclipse on August 2, 2025 An annular solar eclipse on February 28, 2025, visible from parts of the South Pacific Ocean.
