I’m surprised people aren’t jumping up and down everywhere
about the Mars landing. I happened
across a news item some time ago about how they had figured out a way to land a
one-ton piece of equipment, this rover robot, within a few meters of where they
wanted it in a crater on Mars. A mind-boggling
accomplishment.
First they have to
fling this thing the size of an automobile into space. Then they have to wait eight months
while it travels 350 million miles.
Then they have to sit through “seven minutes of terror” as it goes
through some seventy-odd steps to set itself down just right. If any one of these steps had gone
wrong it could have turned itself into a multi-billion dollar piece of junk and
slammed into the surface, leaving thousands of people at the Jet Propulsion Lab
and elsewhere looking like fools.
What a risk they took. What
an adventure.
How could we not get caught up in this? We take technical accomplishments for
granted these days. But this was
at a whole new level. Just one
example: Here’s a picture taken
from a satellite which they fashioned to be able to be in just the right place at
the time the rover robot was landing. One second too soon or too late and
they would have missed it. Let’s
hear it for mathematicians!
Fortunately, thanks to other technical advances, I was able
to watch the landing live. (Me and all the mission controllers and the 1,400
scientists, engineers and dignitaries at JPL and the 5,000 people at the California Institute of Technology, and all the other people who had found their way to this event). Facebook had a
link. Others, as well, allowed you
to go to your computer and watch the folks at the Jet Propulsion Lab in
Pasadena bite their nails and sweat it out. Lots of sites are carrying on with related information. Great drama.
And, because it worked exactly as planned – it was a total
success – you got to feel the excitement.
Imagine working on a project for eight years, going from one
disappointment to the next, one trial and error experience to the next, and
then getting to the last moment and having to sit for those seven minutes when
you couldn’t know whether the landing plan was working – having to wait
seventeen minutes for the data to reach the earth at the speed of light after it had either worked or
not worked. Adam Steltzner, the
head of the landing team, described the team as “rationally confident,
emotionally terrified.”
Quite a show.
Lots of tears. Lots of
hugging.
And lots of politicking. The head of NASA, and the president’s man, his science
advisor, John Holdren, all had to get in on the inevitable rah-rah USA stuff. We are Number One. Don’t you wish you were us? Where does this come from? It’s not just the grunts in the stands
shouting U-S-A, U-S-A at sports events.
It goes all the way to the top. To the political folk, at least – I do
get the impression the scientists working at JPL were more intent on doing
their job than in politicking.
Fine. It’s a
great American moment. We spent
billions on this voyage of exploration, and this time I don’t feel like
complaining that the money should have been spent on school lunch programs
instead, as I do everytime the pentagon spends that sort of pocket change on
killing foreigners with drones.
I’m hoping, as the scientists themselves said, this will inspire kids to
study mathematics and engineering and chemistry and physics. I’m hoping they will see themselves in
the seats of these men and women at the JPL some day, with tears of excitement
running down their cheeks too at some magnificent accomplishment as this, and
get cracking.
I’ve been distracted all week by this tragic display of
American foolishness, this lining up at Chick-Fil-A to show solidarity with a
perfect jerk who turns his profits over to people like the Family Research
Center, a group the Southern Poverty Center calls a hate group. Watching Americans who are either
downright nasty homophobes lining up for crap chicken or clueless suckers
campaigning for their Best Friend Jesus, can make you sour indeed on your fellow
citizens.
But then, suddenly, I was looking at some fellow citizens
with tears rolling down their cheeks, grown men and women, thrilled to the bone
that their engineering project had worked, and we were now in for an
unspecified period of months and years of learning about another planet in our
universe.
A rare and wonderful ride from the ridiculous to the
sublime.
Color me a big big fan of the folks at NASA and the Jet
Propulsion Lab. And the California Institute of Technology. And teachers of math and science everywhere.
