Flight engineer Kalpana Chawla was a native of Karnal, India. Her name is pronounced CULL-puh-na CHAV-la ('cull' rhymes with 'hull'-'puh' rhymes with the 'puh' sound in 'pun') which is rather difficult for most Americans, so she went by her nickname "K.C." She became a naturalized U.S. citizen and was selected as an astronaut in 1995.
K.C. loved to fly, especially in 'tail dragger' acrobatic aircraft.
K.C.'s first spaceflight was the STS-87 mission in November 1997. On that flight she was responsible for the Spartan spacecraft and operating the shuttle's robot arm. She accidentally left out a step in the procedures resulting in Spartan not getting activated. An unplanned spacewalk was needed to capture Spartan and put it back into the shuttle's cargo bay. Chawla was also responsible for operating a variety of microgravity experiments.
Many Indian press have tried to claim that Spartan wasn't her fault or that it was vague instructions and bad software which was actually caused the problem. The investigation board noted those problems but also found K.C. at fault. She's always acknowledged her personal mistakes with Spartan. Her honesty saved her career. Many of her colleagues felt that she went to the extra effort to understand every detail about her responsibilities on STS-107 to make up for what had happened on Spartan.
