If all goes according to schedule,
Scott Parazynski will reach the top of the world
sometime over the next week or so.
Parazynski won't be the first person to reach
the top of Mount Everest, the highest mountain on Earth; Edmund Hillary and Tenzing Norgay have held that record since 1953. He won't
even be in the first 1,000; more than 1,400 have summited
over the past 56 years.
But should Parazynski reach the top, he will be the first person
to do so having first had the opportunity to see Everest from as much as 40
times higher than its 29,000 foot peak.
Going where no astronaut has gone
before
Separating Parazynski
from the climbers that preceded him is his former profession: astronaut. A
veteran of five
space shuttle missions, Parazynski left NASA in
March, just before departing to Everest.
"The timing of this expedition,
it is a very nice transition event," Parazynski
told collectSPACE.com prior to leaving
for the mountain, adding that the decision to retire from the space agency
was "mostly separate" from the excursion.
That said, Parazynski sees parallels between the climb and the seven
spacewalks he made during his career in orbit.
"The workload of carrying your
body out along the summit ridge of Everest or any major mountain is enormous,
so the metabolic workload is much tougher mountaineering, but I think there are
a lot of similarities in terms of the actual technique. You're working with
fixed lines, you're wearing big heavy mitts similar to EVA gloves, you've got
oxygen on, you've got a very limited field of view, you've got a down suit on
and a hood on with goggles, so it is similar in many regards to the [spacesuit
helmet's] visor," he explained. "And your focus and intensity going
out and doing that is very similar."
During his last spacewalk in
November 2007, Parazynski was tasked with repairing a
torn solar array, riding at the end of a long boom attached to a robot arm.
Soaring over the International Space Station, his view
of the Earth and outpost below was unique to past EVAs,
which tended to stay closer to the station's structure.
"The summit of Everest will
have a hard time competing with the view from the boom!" radioed Mission
Control in Houston. They were not however, referring to this current climb;
rather, they were foreshadowing Parazynski's then
upcoming first attempt at Everest.
Parazynski almost became the first astronaut
to summit
Everest one year ago this month when he ruptured a disc in his back.
"I was within a day of topping
out. I could see the route," he described. "Up to that point, I had
been climbing so well, very strong, one of the fastest Westerners climbing on
the hill."
So close to the peak, Parazynski made the tough choice not to push through the
pain and descended. "By the time I arrived at base camp, I already knew
that I had to come back."
The only other astronaut to attempt
Everest was not as fortunate to have a second chance. On October 5, 1993, Karl Henize died of respiratory and heart failure while
attempting to summit the north face of the mount. Buried at 22,000 feet, Henize had flown one shuttle mission and earlier served on
the support crew for the fourth manned lunar landing. He was 67.
Surgery having mended his back, Parazynski hopes that taking additional care will allow him
to not only reach the summit for himself, but also deliver a replica of the
patch that Henize wore in space, as well as Tibetan
prayer flags for the astronauts and cosmonauts who were lost during the pursuit
of space exploration.
