It will cost $104 billion over the next decade
to send astronauts back to the moon,
NASA’s chief said,
defending the price tag as an investment the nation
can afford despite the expense of Hurricane Katrina.
The new moon exploration plan unveiled
by the space agency will use beefed-up shuttle
and Apollo parts and aims to put people on the moon by 2018.
“There will be a lot more hurricanes
and a lot more other natural disasters
to befall the United States and the world in that time,
I hope none worse than Katrina,”
NASA Administrator Michael Griffin said at a news conference.
“But the space program is a long-term investment in our future.
We must deal with our short-term problems
while not sacrificing our long-term investments in our future.
When we have a hurricane,
we don’t cancel the Air Force.
We don’t cancel the Navy.
And we’re not going to cancel NASA.”
The $104 billion price tag,
leading up to an initial four-person lunar landing
and spread over 13 years,
represents 55 percent of what the Apollo program
would cost in today’s dollars, Griffin said.
Apollo development spanned eight years,
from 1961 to the first manned moon landing in 1969.
The new space vehicle design uses shuttle rocket parts,
an Apollo-style capsule and a lander
capable of carrying four people to the moon.
The rockets—there would be two,
a small version for people and a heftier one for cargo—
would eclipse the 18-story space shuttle.
The larger one, in fact,
would come close to the 36-story Saturn 5 moon rocket.
They would be built from shuttle booster rockets,
fuel tanks and main engines,
as well as moon rocket engines.
The so-called crew exploration vehicle perched on top
would look very much like an Apollo capsule, albeit larger.
The crew exploration vehicle would replace the space shuttle,
due to be retired in 2010,
but not before 2012 and possibly as late as 2014
depending on the money available, Griffin said.
It could carry as many as six astronauts back and forth to the international space station.
If all goes well,
the first crew would set off for the moon by 2018—or 2020 at the latest,
the year targeted by President Bush who proposed such an initiative.
The same type of vessel could be used,
one day, to transport astronauts to Mars.
The new exploration plan would allow four astronauts to stay on the moon for a week—
twice as long as Apollo missions.
It also would haul considerably more cargo,
much of which would be left on the moon for future crews.
In time, lunar stays of up to six months would be possible.
