Indian-origin astronaut Sunita Williams set to fly into space for a third time on Tuesday

Starliner will carry Williams, 58, and Butch Wilmore to the International Space Station, marking what could be a momentous and long-awaited victory for the beleaguered Boeing programme.

The scheduled lift-off is set for 22:34 local time on Monday (8:04  am IST on Tuesday) “We are all here because we are all ready. Our friends and family have heard about it and we’ve talked about it and they are happy and proud that we are part of the process to fix it all,” the BBC quoted Williams as saying The mission has been delayed for several years because of setbacks in the spacecraft’s development.

If it is successful, it will become the second private firm able to provide crew transport to and from the ISS, alongside Elon Musk’s SpaceX.

Such a scenario — with both SpaceX’s Crew Dragon and Starliner flying regularly — is one for which the US space agency has long waited.

“Design and development is hard — particularly with a human space vehicle,” said Mark Nappi, vice president and Starliner programme manager at Boeing, during a Thursday news briefing.

“There’s a number of things that were surprises along the way that we had to overcome. … It certainly made the team very, very strong. I’m very proud of how they’ve overcome every single issue that we’ve encountered and gotten us to this point,” Nappi said.

“This is history in the making,” NASA Administrator Bill Nelson said of the upcoming Starliner mission during a March 22 news conference. “We’re now in the golden era of space exploration.” SpaceX and Boeing developed their respective vehicles under NASA’s Commercial Crew Programme, a partnership with private industry contractors. From the outset, the space agency aimed to have both companies operating at once. The Crew Dragon and Starliner spacecraft would each serve as a backup to the other, giving astronauts the option to keep flying, even if technical issues or other setbacks grounded one spacecraft.

Williams received her commission as an Ensign in the United States Navy from the United States Naval Academy in May 1987.

Williams was selected as an astronaut by NASA in 1998 and is a veteran of two space missions, Expeditions 14/15 and 32/33.

She served as a flight engineer on Expedition 32 and then commander of Expedition 33.

During her first spaceflight, Expedition 14/15, Williams was launched with the crew of STS-116 on December 9, 2006, docking with the International Space Station on December 11, 2006. While onboard, she established a world record for females with four spacewalks totalling 29 hours and 17 minutes. Astronaut Peggy Whitson subsequently broke the record in 2008 with a total of five spacewalks.

On Expedition 32/33, Williams was launched from the Baikonur Cosmodrome in Kazakhstan, along with Russian Soyuz commander Yuri Malenchenko and Flight Engineer Akihiko Hoshide of the Japan Aerospace Exploration Agency, on July 14, 2012.

Williams spent four months conducting research and exploration aboard the orbiting laboratory.

She landed in Kazakhstan on November 18, 2012, after spending 127 days in space.

During their Expedition, Williams and Hoshide performed three spacewalks to replace a component that relays power from the space station’s solar arrays to its systems and repair an ammonia leak on a station radiator. With 50 hours and 40 minutes, Williams once again held the record for total cumulative spacewalk time by a female astronaut. The record has since been overtaken by Peggy Whitson. Williams has spent a cumulative total of 322 days in space.

Williams was born in Euclid, Ohio, to Indian-American neuroanatomist Deepak Pandya and Slovene-American Ursuline Bonnie (Zalokar) Pandya.

She holds a physical science degree from the US Naval Academy and a Master of Science in Engineering Management from Florida Institute of Technology. PTI NSA AKJ NSA NSA
