America is
losing the space race. Within two years or less, Russia and China will become
the only nations capable of launching their citizens into space. The decisions
made by this Congress and U.S. President Barack Obama's administration will determine whether this
situation is temporary, or if, like so many other industries, human space
launch is outsourced to more eager, forward-thinking countries.
With the
stakes so high, I felt compelled to respond to Sen. Richard Shelby's (R-Ala.)
comments made at a May 21 Senate Appropriations commerce, justice, science
subcommittee hearing to review the 2010 budget for NASA. After expressing his
support for the Ares/Orion architecture, Sen. Shelby slammed the agency's
funding for commercial crew and cargo transport, singling out Space Exploration
Technologies Corp. (SpaceX) for criticism, and
concluding by referring to commercial programs as a "fantasy." I could not
disagree more.
First and
foremost, before the senator dismisses commercial transport, I would recommend
that he take a hard look at the program he supports. Specifically,
Constellation appears to have become an unmitigated disaster from nearly every
perspective — technical, financial and chronological.
Like
everyone else in America, NASA is facing a new economic
reality, and the days of budget busting program overruns must come to an end.
Unfortunately, Constellation appears to be yet another ill-conceived NASA
boondoggle suffering from all too familiar runaway costs. According to the
Government Accountability Office (GAO) there are so many technological
"unknowns" surrounding the Constellation effort that it would literally be
impossible for NASA to provide a credible cost estimate. All the GAO could say
for certain is that Ares/Orion is estimated to cost U.S. taxpayers $230 billion
over the course of the next two decades. Such expenses are unsustainable and
unwarranted. To put these figures in perspective, even at Russia's outrageous price of $51 million
per seat on Soyuz, NASA could fly 4,509 astronauts — 225 astronauts per year
for the next 20 years — in lieu of Constellation.
Moreover,
spending such outrageous sums of money presupposes that Ares/Orion can function
at all, which is anything but a forgone conclusion. The system has been
suffering from well-documented mass issues as well as deadly vibration
problems, and liftoff drift. Confidentially, many NASA engineers have expressed
to various media outlets that they question if these fatal flaws can ever be
sufficiently addressed, and have warned that, even if they can, the cost of the
system would become even more extraordinary. Just as important is the issue of America's spaceflight gap, and, again, due
to the aforementioned technical challenges, ongoing budget shortfalls and
inherent schedule creep, it is highly unlikely that Ares/Orion will go into
operation any earlier than seven or eight years from now — and even those
estimates may be overly optimistic.
However,
most damning of all is the number of seats provided by Orion. Because of the
Ares mass issues and other challenges, Orion will now only be capable of
carrying four astronauts. This represents half of the seats the shuttle could
provide, and only one more than the ancient Russian Soyuz. A mere four-seat
capability would be unacceptable to the private sector and should be
unacceptable to NASA as well.
When placed
in this context, it is readily apparent why supporting a commercial alternative
— and SpaceX in particular — is so important. In six
short years, from nothing, SpaceX has built world-class
facilities, hired an experienced and talented staff (which now numbers over
seven hundred), designed two iterations of its rocket (Falcon 1 and Falcon 9)
as well as a capsule (the Dragon), and conducted four launches, one of which
was a fully successful mission. By any standard, this represents outstanding
progress, but particularly so in the unforgiving field of space launch. Add to
this the fact that SpaceX has been funded primarily,
and at first entirely, by private sector investment, and for an overall cost
that is a mere fraction of the expense of a single shuttle launch, and SpaceX's success and value becomes obvious.
SpaceX's
work on the Merlin engine represents the first new U.S. rocket engine development program
in nearly three decades, making SpaceX's work and
technologies nothing short of a national asset. It is true that SpaceX has had one successful launch out of its first four,
but such results are an inherent part of rocket development, and an expected
aspect of any new program. I defy Sen. Shelby to point out any new rocket
development effort, foreign or domestic, that did not suffer similar losses or
worse when it first began.
Additionally,
from a pricing perspective, SpaceX promises to be
revolutionary. If SpaceX can come close to its current
price estimates, it will change the launch industry as we know it and restore
America's lost leadership in the field of international commercial space
launch. While carrying astronauts represents a more significant challenge than
cargo, given another five years, SpaceX may develop
this capability as well, potentially even before Ares/Orion (again, at a
fraction of the cost), which is perhaps why SpaceX
and commercial crew transportation has been so vociferously attacked by
Constellation supporters.
Finally, it
is vital to note that when Sen. Shelby condemns commercial space transport, and
limits his comments to SpaceX alone, that he is
creating a false dichotomy. This omission is particularly inexcusable since the
Atlas 5, a leading commercial transport contender, is produced
in his home state of Alabama. Bigelow Aerospace has studied human-rating the
Atlas 5 and found the concept to be both viable and economically attractive.
The Atlas quickly defeats many of the senator's criticisms since the system has
enjoyed 86 consecutive successful launches, and, with the addition of a crew
abort system, a human-rated Atlas 5 could offer greater than 99.9 percent crew
ascent survival probability, a figure that far surpasses both that of the
shuttle and Soyuz.
Commercial
crew transport, as demonstrated by SpaceX's dramatic
progress and the existing Atlas 5 launcher, represents a viable, affordable and
robust path forward. Due to the disturbing questions and potentially fatal
problems surrounding the floundering Ares/Orion program, as well as more than
two decades worth of similar failed NASA-driven human spaceflight initiatives
(e.g., Venturestar/X-33, Crew Transportation Vehicle, Orbital Space Plane,
etc.), Senate appropriators ignore the commercial option at their peril.
Moreover, to hear a Republican senator espouse the virtues of a bloated, costly
government program over innovative commercial concepts is so paradoxical that
it requires no further comment from me.
We have a
great deal of respect for Sen. Shelby, and simply hope that he will re-evaluate
his thinking on this matter and recognize the danger in entrusting America's
human spaceflight future entirely to a deeply flawed government quagmire.
Commercial crew and cargo transport is a real and viable option, and for a
relatively minor amount of funds NASA could support both SpaceX
and an Atlas 5-based system. If America focuses on developing these commercial,
entrepreneurial options, I am confident that we can not only get back into the
space race, but stand a good chance of winning it.
