Forty years ago, NASA launched America’s first space
station. Skylab, built using leftover
Saturn launch vehicle components, hosted three different crews. The Skylab IV crew stayed for 84 days, a
record in the US space program at that time.
Watching videos of the Skylab astronauts working and playing in a weightless
environment was one thing that inspired me to study science and math.
After the last crew left Skylab, it was abandoned, its orbit
slowly decaying over time. NASA was busy
developing the Space Shuttle and had no capability to return crews to
Skylab. When it appeared that the Space
Shuttle might be ready to fly by 1979, NASA looked into reusing Skylab. Unfortunately, greater-than-anticipated solar
activity caused Skylab’s orbit to decay quickly, resulting in re-entry in 1979. The Space Shuttle first flew in 1981, and the
first elements of the International Space Station (ISS) flew in 1998. In between 1981 and 1998, the US space
program was constrained to flying in low Earth orbit for durations of two weeks
or less.
Forty years later, we are in similar straits. We have a space station, but no US launch
capabilities to get a crew there. We rely
on a Russian launch vehicle and spacecraft to get our crews to the ISS and home
safely. We have plans for a new spacecraft
and a launch vehicle to get crews to the ISS, but what mission comes next? Current US space policy is to continue
operating the ISS, begin crewed missions beyond the moon, and send humans to
orbit Mars by the mid-2030s. While these
are big goals, where is the inspiration that accompanied Kennedy’s challenge to
send us to the moon before the end of the 60’s?
The big difference between when NASA launched Skylab and today
is that spaceflight has become so commonplace that it doesn’t pique the
interest of most people. So few students
enter fields of study in science, technology, engineering, and mathematics
(STEM) that the US Department of Education, the National Science Foundation,
and many technology companies have partnered
together to make STEM education a national priority. I wonder if more technological feats in space
would inspire kids to enter STEM fields.
Recently, ISS crew
members performed an emergency spacewalk to replace a coolant pump. Most spacewalks are planned weeks in advance
of execution. In this case, the
spacewalk was planned and executed in the roughly 48 hours after a coolant leak
occurred, demonstrating that we can work safely in space and repair systems when
needed. It is hardly surprising that
there is more interest on the Internet over ISS Commander Chris Hadfield’s
rendition of “Space Oddity” than the ISS crew’s success over a technological
challenge.
Another big difference is what we know today about space
compared to the days of Skylab. The ISS
has been crewed continuously for nearly 13 years, with most crews staying for
six months at a time. We have wealth of
knowledge on how to live and work in space, how space affects the human body--both
physically and psychologically--and how to work in a weightless
environment. Furthermore, we’ve gained
experience with the hardware, knowing what does and doesn’t work well in the
space environment. And we’ve learned some
hard and painful lessons along the way. Because we can track how far we have come,
shouldn’t it inspire us to see how far we can go?
If our leaders are truly interested in inspiring students to
enter STEM fields of study, what better way than to provide a space program
that inspires. To do that, our space
program needs a mission with concrete, near-term goals and milestones and the
resources to see it through. Give NASA a
goal, a milestone, and the resources to achieve the mission and then let NASA
go do it.
Tell your Congressmen and Senators you want your space program to boldly go where no
man has gone before. In the process, we
might just inspire the next generation of scientists, mathematicians, and
engineers.
