NASA to Set Biggest Man-Made Fire in Space
There should be a saying “Never play with fire in Space,”
due to the obvious possible hazards astronauts might face in the cold, desolate
environment. However, that is exactly what NASA intends to do with their Cygnus
cargo spacecraft in its first-of-three Saffire experiments.
“A spacecraft fire is one of the greatest crew safety
concerns for NASA and the international space exploration community. Saffire is
all about gaining a better understanding of how fire behaves in space so NASA
can develop better materials, technologies and procedures to reduce crew risk
and increase space flight safety.” Gary Ruff, Project Manager, Saffire. Saffire
is a joint-initiative between researchers from 11 government agencies and
universities.
“Saffire will be the biggest man-made fire ever in space,”
Ruff adds.
Tomorrow (on March 22), NASA’s commercial partner Orbital
ATK will proceed with the launch of Cygnus, a cargo spacecraft that will
transport food, water and other supplies (including experiments) to the
International Space Station (ISS). A particularly interesting experiment with
an equally-interesting name is called Saffire-I, or Spacecraft Fire Experiment,
and NASA intends to test the effects of fire in a weightless environment such
as outer space.
"NASA's objective is to reduce the risk of
long-duration exploration missions, and a spacecraft fire is one of the biggest
concerns for NASA and the international space exploration community,"
Jason Crusan, Director of Advanced Exploration Systems, NASA.
After stocking up with ISS with its supplies, Cygnus will
descend to a lower orbit to ‘ignite’ the experiment. Ground operators in Virginia
will set fire to a thin piece of material 3.2 x 1.3 feet in a box full of
sensors and other equipment located inside the spacecraft. The fire is
estimated to burn in about 15-20 minutes. During the test, sensors will record
and measure oxygen, carbon dioxide, temperature, pressure and other key metrics.
“Saffire seeks to answer two questions. Will an upward
spreading flame continue to grow or will microgravity limit the size? Secondly,
what fabrics and materials will catch fire and how will they burn,” David Urban,
Saffire Principal Investigator, explains.
Data derived from the Saffire experiments will be used for
future space missions, such as Orion’s planned asteroid mission and NASA’s goal
to put humans on the planet Mars.
Fire has been a major issue in space exploration ever since
man dreamed of reaching the moon. Apollo 1, set to make history as the first
manned Apollo flight, suffered a tragedy as a fire erupted during a pre-flight
test killing Gus Grissom, Roger Chafee and Ed White. For the whole story, read -
