Six teams
from across the country are converging on Connecticut this week to determine
which among them has built a better space glove in a NASA-sponsored
competition.
The two-day
competition, billed as the Astronaut Glove Challenge, begins May 2 at the New
England Air Museum at the Bradley International Airport in Windsor Locks, where
a total of $250,000 in prize money is at stake. The contest is one of several
competitions under NASA's
Centennial Challenges program which offer cash prizes to spur innovation and
interest in spaceflight technology.
"We're
looking for something different, to show us something unique," said Alan Hayes,
CEO of the non-profit Owings, Maryland firm Volanz Aerospace, which is
overseeing the Astronaut Glove Challenge for NASA.
Build a
better space glove
Spacesuit
gloves are among the most important components of an astronaut's spacesuit,
especially during hours-long spacewalks to perform construction or maintenance
outside a vehicle such as the International Space Station (ISS). Astronauts
have endured cold fingertips and broken fingernails, as well as bruised and
bleeding hands, to overcome the resistance of their pressurized spacesuit
gloves while working long hours in space, NASA said in a statement.
"Spacesuit
design has a way to go and we're starting with the glove, which is probably
going to have the biggest impact on the astronauts," Hayes told SPACE.com.
NASA's
Astronaut Glove Challenge offers a $200,000 prize for the team that presents
the best astronaut glove that surpasses the minimum requirements set by NASA's
baseline Phase VI glove. A separate, $50,000 award is reserved for the
Mechanical Counter Pressure glove joint demonstration that compares glove
dexterity and flexibility.
To
win the challenge, competitors must supply two different astronaut gloves to be
used in three separate tests, NASA has said.
First,
each glove will be measured to determine the amount of force required to move
its fingers and thumb. The glove with the least force wins the most points.
Then,
each team will use one of the gloves to perform dexterity tasks within a
depressurized glove box. The more tasks completed within a specified time wins
more points. Finally, one glove from each team will be subjected to a burst
test to determine how much internal pressure they can withstand.
The
team that wins the most points while exceeding the performance of NASA's
current spacesuit gloves will win the Astronaut Glove Challenge.
Competitors
are not required to provide their own thermal or micrometeorite garment, which
wrap around the outer layers of NASA's current spacesuit gloves for added
protection against the space environment. It was that outer glove layer that
suffered a thin slice about three-fourths of an inch (about two centimeters)long to its palm during one of four
spacewalks performed by veteran astronaut Robert Curbeam as part of NASA's
last shuttle flight in December.
Engineers had to use a microscrope to ensure that the glove was in fact damaged and not weathered by normal wear and tear, NASA
spokesperson Brandi Dean told SPACE.com.
Hoping for a winner
The Astronaut
Glove Challenge is the fourth NASA contest to be performed.
The
agency's Beam
Power and Tether challenges, in which entrants construct light-powered
climbing robots and strong tethers, met in 2005 and 2006, yielding no winners
despite a prize purse of $200,000 per event last year. The Northrop Grumman Lunar
Lander Challenge, which offered a $2 million prize for privately
built vehicles capable of vertical takeoffs, landing and in-flight hovering,
met in October 2006 at the Wirefly X
Prize Cup and also ended without a champion.
Another
competition, the 2007 Regolith Excavation Challenge, calls on entrants to build
their own autonomous Moon dirt digging robots. The first meet for that contest,
with $250,000 in prize money up for grabs, is scheduled for May 12 in Santa
Maria, California.
Hayes said
the space glove contest would go on even if none of its six competitors make it
through the qualifying stage.
"Everybody
could fail on Day One, but we're still going to go through with the
competition," Hayes said. "I'd love to be able to give out a $250,000 check on
Thursday."
