As he was training in 2004 for his second space flight to help in the construction of the International Space Station, a routine visit to the doctor almost cut short Dave Williamssa国际传媒� career as an astronaut.
Williams, a physician himself, had gone for his annual checkup to maintain his flight status as an astronaut and pilot when a blood test revealed he had prostate cancer.
He was three years away from the planned 2007 space station mission, but suddenly everything was on hold.
Williams titles his new memoir, sa国际传媒橠efying Limits - Lessons from the Edge of the Universesa国际传媒�, but the book reveals it was back on Earth that he faced some of his greatest challenges.
sa国际传媒淚 sort of forgot that I was a doctor when I heard the news. All of a sudden I had the feeling that sa国际传媒極h, my goodness, Isa国际传媒檝e got cancer, Isa国际传媒檓 going to diesa国际传媒�,sa国际传媒� Williams, 64, told The Canadian Press.
sa国际传媒淔ortunately, the rational part of me sort of kicked in, and I started to approach this as I would if I was another patient sa国际传媒� even though the patient was myself.sa国际传媒�
NASA found a surgeon for Williams at Memorial Sloan Kettering Cancer Center in New York City, and he had his prostate removed in August 2004.
While performing the procedure, doctors discovered the tumour had spread, but they were able to get it all. Williams was given the green light to continue training for his space voyage.
The cancer scare came the year after another trauma for Williams. In February 2003, the U.S. space shuttle Columbia broke up while returning to Earth, killing seven astronauts sa国际传媒� all close friends of Williams.
He took part in recovery efforts searching for debris, and recounting that chapter of his life was tough.
sa国际传媒淚sa国际传媒檇 write a couple of paragraphs and then Isa国际传媒檇 quite literally have to take a break and go do something else and come back to continue writing,sa国际传媒� he said. sa国际传媒淚t was a very sad time for us in the program.sa国际传媒�
During his 2007 space station visit, Williams helped installed a truss on the orbiting laboratory and performed a Canadian record of three spacewalks.
It was during his second sortie, perched on the Canadarm, that he gazed down at Earth awestruck. He realized he was sa国际传媒漧ooking at this incredible four-and-a-half-billion-year-old planet upon which the entire history of the human species had taken place,sa国际传媒� he said in the interview.
His first space mission was on board the shuttle Columbia in April, 1998 sa国际传媒� the same orbiter that blew up five years later. During the 16-day flight, while serving as a mission specialist, Williams carried out neuroscience experiments that focused on the effects of microgravity on the brain and nervous system.
Born in Saskatoon, Williams grew up in Montreal. His dream of becoming an astronaut began just before his seventh birthday when he watched on a black-and-white TV as astronaut Alan Shepard took a sub-orbital flight in May 1961, becoming the first American in space.
His book recounts setbacks large and small that he experienced as he pursued his dream. In Grade 5, while living in suburban Montreal, he was struck by a car on his bike while headed to school but escaped without serious injury. Later as a teenager in the Royal Canadian Army cadets, he was thrown from a military truck when it overturned, but he managed to walk away with some scrapes and aches.
A more sobering moment came during the Canadian Space Agencysa国际传媒檚 astronaut selection process in 1992, when an eye exam revealed Williams had a degenerative condition of the retina. The degeneration turned out to be mild, and the Canadian Space Agency selected Williams and three others to join the astronaut corps.
Williams met his wife Cathy, who went on to become an airline pilot, at a swimming pool in a Montreal suburb in 1978.
He recounts how despite his busy schedule, he tried to stay in touch, even at the most improbable moments. During his first space trip, Williams sent a message directly to his wifesa国际传媒檚 Air Canada cockpit while she was co-piloting a flight between Montreal and Toronto.
sa国际传媒淲e are having a great time orbiting the Earth at Mach 25 much higher than flight levels,sa国际传媒� it read. sa国际传媒淧lease extend best wishes sa国际传媒� to the captain, the crew and all passengers.sa国际传媒�
The captain flicked on the planesa国际传媒檚 PA system and read the message to the entire plane, prompting a round of applause.
Williams has a daughter Olivia and a son Evan as well as a nephew Theo, who came to live with the family after losing both of his parents to cancer. Evan was diagnosed with Down syndrome when he was born in 1994, but for the Canadian astronaut it was just another personal challenge.
sa国际传媒淟ife is full of adversity, and I donsa国际传媒檛 think Isa国际传媒檓 unique in that way,sa国际传媒� Williams said in the interview.
sa国际传媒淚 think most people in their lives have had challenges at one point or another, and I think it is how we respond to those challenges that, in part, brings meaning to our life.sa国际传媒�
The book, which was released Oct. 30, is published by Simon and Schuster Canada.
