Delhi: the date of Indian origin American’s astronaut Kalpana Chawla and sex others on February 1, 2003. when the space shuttle Columbia broke up and burnt as it re-enter the earth atmosphere played heavily in the minds of NASA officials who decided, to keep another Indian origin American astronaut, Sunita Williams and space for 8 months.
Before the Columbia accident the space shuttle Challenger had exploded and kill all crow on January 28, 1986.in all 14 astronauts have lost their lives in this accident.
The two accidents” very much affected the decision” to bring Boeing starliner back without the astronauts, “NASA” chief bill Nelson, who is himself and astronaut and has been part of the investigations into the two space shuttle accidents. his side obviously mistakes were mades “by the national aeronautics and space administration “NASA”.
Kalpana Chawla died of skies in Southern US when the space shuttle Columbia and her crew broke apart during re–entry, 16 minutes prior to the schedule landing she went to Tagore school in haryana’s kernel in 1976, and graduated with BSc degree in aeronautical engineering from Punjab engineering college in 1982 she is Joined “NASA” as an astronaut in 1994, after completing for the education in the US.
Mr. Nelson, side the culture in NASA back then was such that despite junior’s flight engineers warning of Risk non heard them. “today, folks are in encourage to speak their minds,” he added.
So, NASA took the decision to bring home astronaut Sunita Williams and butch will more in February. 2025, instead of now, in the space X crew dragon after engineers spoke their mind about the risks involve in flying the spacecraft in it is current conditions.
“NASA” official side the decision to replace the returns spacecraft was unanimous.”
Space flight is risky, even at it is safest and most routine, a test flight by nature, is neither safe nor routine the decision to keep butch and Suni aboard the international space station “ISS”and bring Boeing starliner home without crewed is the result of our commitment to safety — our core value and our North Star,” side MR. Nelson.
Space engineer identified helium leaks and experience issues with the spacecraft reaction control thrusters small rockets on June 6, as sterliner approach the ISS.
NASA in statement had side the “uncertainty” and lack of expert concurrence does not meet the agency safety and performance requirements for human spaceflight.”
NASA announce it will bring home Boeing star linear without the two astronauts by September six .it will take 6 hours to return the starliner to earth. the spacecraft has had to uncrewed missions before this one and boeing his hopeful that it will return safely.
Kalpana chawala missions, Sunita Williams, sterliner and the additional risks. :
The launch of Boeing sterliner spacecraft, which carried “NASA’ Sunita Williams and Butch will more to the international space station in June 5 , was delayed twice. despite the issues with the spacecraft,it was launched it on June 5 and suffer anomalies during the journeys.
Starliner, initially Schedule to launch on May 6, 2024 ,was delayed due to suspect oxygen relife value on the Atlas Ve rocket centre second stage,” NASA side.
