CAPE
CANAVERAL, Fla. — A prototype version of NASA's newest
rocket is ready for its planned Tuesday launch, mission managers said today.
NASA
is set to test the design of its next-generation
rocket, Ares I, during a demonstration liftoff called Ares I-X. The launch,
slated for 8 a.m. EDT (1200 GMT) on Oct. 27 from Launch Pad 39B at Kennedy Space Center
here, will be a suborbital flight of the new rocket's first stage, with a dummy
second stage and mock crew capsule on top.
NASA
officially gave the go-ahead for Tuesday's
launch after a Flight Test Readiness Review meeting among mission managers.
"The
team is ready to go fly," said Bob Ess, Ares I-X
mission manager, at a briefing following the meeting. "The vehicle is
actually ready to go fly."
But
the weather outlook for Tuesday is iffy, with only a 40 percent chance of
favorable conditions expected. NASA requires clear skies for the launch so that
the rocket's flight is visible and detailed data can be collected.
"Weather
is always a challenge and next week will be no different," said Ed Mango,
Ares I-X launch director. "But we're five days out and a lot can change in
those five days."
If
NASA can't launch Ares I-X on Tuesday, it can try again on Wednesday. On both
days, the rocket only needs about 10 minutes of good weather sometime between 8
a.m. and noon EDT (1200 and 1600 GMT).
The
Ares I rocket is NASA's chosen rocket to replace the aging space shuttle fleet
as a vehicle to carry astronauts to low-Earth orbit.
But
whether NASA will actually build Ares I hinges on an upcoming decision by
President Barack Obama's administration, which is currently assessing the
results of an independent review of U.S. human spaceflight plans. The review
panel released
a final report Thursday that raised the possibility of nixing Ares I and
encouraging commercial
aerospace companies to build a crew-carrying launch vehicle. That would
allow NASA to focus on designing the technology and heavy-lift rocket to take
humans to the moon, Mars, or nearby asteroids, the panel said.
"We
are happy that the report is released and we have that to work with," said
Doug Cooke, associate administrator of NASA's Exploration Systems Mission
Directorate. "We are assessing our options. No decisions have been made at
this point."
Whether
or not the new rocket is approved as part of NASA's
future goals, the Ares I-X test marks a major milestone for the agency.
This is NASA's first test flight for a new crew
launch vehicle since the first space shuttle was launched in 1981. Cook said
the flight is still vital to NASA even if Ares I is
not in the cards for the agency's future.
"We
believe, and actually feel very strongly, that this test is very important for
a number of reasons," Cook said. "Even getting to this point today
this team has learned about getting a vehicle designed and ready to launch, and
it's really an inspiring point to be at ... The data is important to us regardless
of what comes next."
