Here’s a word Americans should learn to become very familiar
with: LEO, pronounced just like the zodiac sign, though in this context it’s an
acronym for Low-Earth Orbit, a distance of a couple of hundreds miles above the
planet’s surface, such as where the space station flies.
It’s the only place we’ve been in space since 1972 when the
last Apollo crew returned from the moon and it’s the only place that anyone
else in the world that has managed to send people into space has ever gone.
America had high hopes of breaking out of LEO after the
shuttle program ends, going back to the moon, maybe out to an asteroid and then
eventually on to Mars, the holy grail of human space exploration. NASA got
started on the job with great enthusiasm and due diligence, racking up a $7.7
billion tab of the estimated $40 billion needed just to develop a new rocket
and capsule for astronauts to ride in.
Along came our new leader, President Barack Obama, who
decided to take stock. He appointed a panel of 10 wise men and women, headed by
the well-respected former chief executive of Lockheed Martin. They spent three
months listening, studying, assessing, analyzing, debating what the country was
doing, should be doing and could be doing with its human space flight program.
The panel’s summary report was released yesterday. In a
nutshell, it says that without more money for a government-run space program, America
will remain in LEO for the foreseeable future. In other words, after building a
$100 billion outpost in orbit, our only option is to use it.
I’m sure that the Augustine report will prompt immediate
calls to increase NASA’s budget, and maybe that’s a good thing. But say
legislators, still slugging it out over health care, don’t take heed and NASA has
to live on roughly $18 billion a year. What would it do?
Seems to me like NASA needs a new story line. Yes, seeing
people in strange environments is interesting, and we love swelling with
national pride, but we’re easily pleased. We’re happy following the antics of robots
stuck in Martian soil.
It’s hard to imagine people shedding tears over the fact
that they may not live to see astronauts walk on the surface of Mars. It’s
easier to imagine the joy on their faces if they’d get to go to space
themselves, even (especially!!) to LEO.
Will Whitehorn, the president of Virgin Galactic, told reporters
yesterday his firm has collected $40 million in deposits from people willing to
pay $200,000 to experience a couple of minutes of spaceflight in a sub-orbital
rocketship, which is on schedule to debut in December.
Space Adventures is getting ready to send its seventh
tourist to the space station, at a cost of about $35 million, which includes
training and transportation from Russia.
Though it was tasked to come up with options for the U.S.
human space program, the Augustine panel slipped in a few recommendations,
including extending the planned life of the space station, which is scheduled to
be finished next year.
“It seems unwise
to de-orbit the Station after 25 years of assembly and only five years of
operational life,” committee members wrote in the report.
“Not to extend its
operation would significantly impair U.S. ability to develop and lead future international
spaceflight partnerships,” they added.
The government has allocated no money for station operations
after 2015.
The report also suggests that it is time for the government
to stop flying people to LEO, that the commercial sector is ready to compete for
this business.
At an impromptu teleconference as the report was being
released, representatives from commercial space launching firms echoed the
sentiment.
“Looking at the size of the industry at the moment is not really
the question to be asking,” Whitehorn said.
“You’re looking at what kind of industry you’re going to create,
what kind of new jobs you’re going to create and what kind of new technologies are
going to come out in supplying a “simple” solution to NASA, which can allow it
to get on with the more important job in the future of human exploration, unmanned
exploration, research and development, and Earth climate change science. These
should be the priorities for NASA. They shouldn’t be a ferrying company.”
LEO may be the end of the road for NASA, but for the rest of
us, it’s just the beginning.
