I usually don’t
blog on the weekend. I’m usually at the ice skating rink at this
time on a Saturday. But amazing feats of science and engineering
don’t limit themselves to weekday work hours. Right now, I’m
geeking out to the latest successful launch and landing by private
rocket company Blue Origin!
After I earned my
master’s degree in high-energy astrophysics in Huntsville, I
switched over to “experimental planetary science” (my phrasing)
at the University of Central Florida with Dr. Josh Colwell as my
advisor.
Josh was working on
a number of projects, but one that caught my attention was the study
of how space and planetary dust (regolith) interact at very low
velocities. When the grains or clumps collide, do they stick
together, bounce, break apart, or what? Most of what could do in the
lab in 1 g (Earth’s gravity) was even faster than we wanted to
observe. We built a drop tower in the lab to examine our experiment
in microgravity, but our short tower only allowed less than a second
of free fall. We wanted more. I flew on two parabolic aircraft
campaigns with Josh to gain a few more seconds of microgravity per
parabola. But still, we wanted more.
Josh had flown an
experiment on orbit on the International Space Station, COLLIDE,
Collisions Into Dust Experiment. He was preparing another version of
COLLIDE to fly suborbitally on a Blue Origin experimental rocket. I
was intrigued by the partnership with an emerging commercial space
company. For my first year and a half in the lab, I participated in
teleconferences with Blue and worked on preparing the experiment for
launch. The engineering students on our team did most of the work,
but I was pleased and excited to participate in any way I could.

But in 2011, Blue
Origin’s test rocket malfunctioned and was destroyed. Our chance to
fly COLLIDE with Blue was postponed indefinitely. We were all
disappointed, but that’s the way it works in the space industry.
This stuff is hard and set-backs happen.
I’ve been
out-of-the-loop with the experiment since leaving UCF. But yesterday,
I heard the exciting news that COLLIDE would launch soon. And this
morning, it did just that. Blue Origin’s rocket New Shepard launch
and landed successfully in Texas.
We’re all
currently awaiting the release of the official video of the
successful test. I’m awaiting news of how my grad school team’s
experiment fared. Knowing first-hand just how tricky those experiment
boxes can be, I’m crossing fingers and hoping for the best.
