Was the eclipse all you expected? No! It was way MORE!

Wow, wow, and triple wow! I expected the eclipse to be pretty cool, but it was absolutely mind blowing! Prof. Koch and I spoke with our Dean last spring and the three of us agreed that he and I needed to be on the path of totality in spite of that day being the first day of class. We were prepared from a gear perspective. We had an 8″ and a 12″ telescope, both fitted with white light solar filters, our new solar telescope with a built-in hydrogen-alpha filter to see prominances, and no less than six DSLRs between us with everything from a fisheye lens to a 400-mm f/4 prime lens. We hosted around 100 people including my fellow space physics researchers at Fundamental Technologies, science educator friends from Rockhurst University, racing buddies from the Sports Car Club of America (SCCA), and of course several other friends and professors and Dean Miller from JCCC.

Prof Koch and I started getting things set up pretty early, around 8am. As we looked to the southwest, though, we saw the rain coming and quickly grabbed some plastic sheeting and covered the telescopes. Thankfully, we didn’t get the torrential rains that the KC Metro received, but it did put a damper on our enthusiasm. The eclipse started a little after 11:30am, but our skies were still completely cloudy overhead. We held on to hope, though, as we could see a patch of blue sky approaching. A little bit past noon, after we had all stuffed ourselves on pulled pork, moon pies, sun chips, and enough potato salad to feed an army, the clouds broke and we had crystal clear skies. Just in time!!!

We watched the partial eclipse deepen using our various cameras, telescopes, eclipse glasses, and pinhole projectors. As the eclipse deepened, it became darker and darker. The dappled light under the trees started to appear more crescent shaped, and we all began to get excited. When totality finally came, I don’t think there was anyone who wasn’t blown away by the sight.

In the shadow of the Moon, we saw what looked like a sunset all around us on every horizon, the temperature dropped, and we saw a couple of planets and bright stars. Of course what was really spectacular was seeing the solar corona. My research focus for the past twenty years has been the solar corona and space weather, but Monday was the first time I have ever seen the object of my research with my own eyes. It was moving beyond anything I had expected.

Our location enjoyed a little over two minutes of totality, but it seemed like only two seconds. Just like that, the Sun began to peek out from around the Moon once again and back on went the filters and the glasses. We admired the partial eclipse a while longer and marveled at the rapidly brightening skies, but then we milled around, some of us packing up, some of us going back for more food. It was Leo, a friend and member of the Astronomical Society of Kansas City, that pointed out the crazy fact that there was a solar eclipse still happening right above us, but after totality, we had all gone back into our routine habits as humans.

As an avid photographer, of course I had gear set up to record the eclipse, but I didn’t let the photography of the event get in the way of my experiencing the event. I had my exposures all preplanned and the camera able to fire with a remote shutter release allowing me to image the sun while not needing to always be peering through the view finder.

The Van Allen Probes Turns 5 Today

Five years ago today, the Van Allen Probes were launched into orbit to begin their study of the trapped radiation belts first predicted by and then discovered by Dr. James Van Allen with the first US satellite, Explorer 1.  Fundamental Technologies in Lawrence, KS, where I do my space science research, is the Science Operations Center for the RBSPICE instruments on the two twin Van Allen Probes spacecraft.  Through my work at FunTech, my wife and I had the honor and privilege of being invited to the Kennedy Space Center to witness our spacecraft leave the planet.

We were at Cocoa Beach for three nights where during the day we interacted with visitors to the Kennedy Space Center where we had a large display assembled sharing information about the mission, its objectives, and its importance to improving our understanding of space weather.  As invited guests, we were given the opportunity to witness the launch from the same grandstands in which the families of the Apollo astronauts watched their husbands, brothers, and sons blast off on their epic voyage to the Moon.  It was an awe-inspiring, thrilling, and ultimately frustrating experience.

We had three nights and therefore three opportunities to get the Van Allen Probes off the planet, but on the first night, a launch was not even attempted.  Engineers had discovered a flaw in one of the RD-180 engines in Huntsville, AL, the same type of engine that powered the Atlas V rocket underneath our spacecraft.  The engines for our launch vehicle were inspected and found to be fine, so we were back on for night number two.

The launch window opened at 0430 which meant that we needed to arrive at Kennedy by 0030 to meet the shuttle busses that would take us to the viewing stands.  Once at the viewing location, we had a magnificent view of our launch vehicle standing on its pad and illuminated by the brightest lights you can imagine.  The atmosphere at the viewing site was thick with tension, anticipation, and mosquitoes.  Lots of mosquitoes! During the long countdown, several speakers gave talks about the mission, which we all knew about already, and details about the launch sequence and timeline, which many of us did not know.    What was truly special is that Maj. Gen. Charles Frank Bolden, Jr., Director of NASA, came out to address us and witness the launch with us.

At 0400, we reached the T-4 minute hold.  This was a preplanned hold during which final checks on the launch vehicle, the two Van Allen Probes spacecraft, and the launch conditions were made.  Talk about tense and exciting!  Movies always make the launch readiness poll sound over dramatic and you come away thinking, “Surely it’s not really that tense.”  Yes it is; it really is.  As each system was called out, the person responsible for that system would call out either “Go!” or “Go, Flight!”  I get goosebumps even now just thinking about that moment.

The Flight Director eventually got around to calling out, “Range.”  The response was a pause, and then an utterly disheartening, “No go, Flight. No go.”  That brought everything to an immediate halt.  When there’s a range fault, it could mean that there’s someone in the restricted space in the air or ocean that’s fouling the range, or it’s an instrumentation failure.  Many of our thoughts in the grandstands was that if it were a bunch of boaters out where they shouldn’t be, there might be violence done that day.  As it turned out, it was the fault of a transponder on the launch vehicle that couldn’t maintain a frequency lock on the downrange radar.

All launch vehicles are actively tracked.  A radar site doesn’t simply passively track them, they actively communicate with the launch vehicle to monitor the rocket’s attitude and trajectory with great precision.  The reason for this is that if a rocket begins to stray from its designated trajectory and begin headed inland where it may fall on a populated area, the vehicle will be destroyed instantly.  The last thing NASA wants is for a US missile to land and explode in a US city.

So with no launch on the second night, we all went back to our hotel rooms, caught what sleep we could before going back to the Visitor’s Center and our booth to do more public outreach in the afternoon.  That night, we all got up again and went back to Kennedy at 0030 to give the launch one more try.  Again with the speeches.  Again with the explanations.  Again with the waiting, the tension, the anticipation, and swarms of mosquitoes.  Once again, we reached the T-4 minute hold.  Once again, we listened nervously to the launch readiness poll.

“Hydraulics.”

“Go!”

“Water.”

“Go!”

“Range.”

And after a long pause, “Go, Flight!”

There was an uproar of cheers!  It was as our team had just won the World Series!  Everyone was jumping, clapping, and cheering, but the poll wasn’t over yet.

“Weather.”

“…No go, Flight.  Weather is no go.”

It was a soul-crushing moment.  All the anticipation, all the excitement was dissipated in an instant. The weight of all of the work that had gone into making the Van Allen Probes, its array of instruments, and all of the software to control the spacecraft and their instruments crashed down upon us.  For many of us, myself included, this was our first time, perhaps the singular time in our lifetimes, of getting to witness a rocket launch, and certainly the singular time we would be able to watch from such a historically significant location.  There were tears.  I’m not ashamed to admit it.

My wife and I along with my fellow colleagues flew home.  There was still work that needed to be done on other missions, and the Fall semester had started, so I had to get back to the classroom.  It wasn’t a fun trip back, and I moped around campus that Monday.  The Van Allen Probes obviously did launch successfully, but not until the Thursday of the week after we were there.  My newborn daughter and I were up at 0300 to watch the launch on NASA TV, and again I wept. This time happy to see our spacecraft finally on their way during a flawless launch.

Five years later, the two spacecraft are still going strong and providing truly unique perspectives and data on the working of the Earth’s trapped radiation belts, the ring current, and space weather in general.  We’re still the Science Operations Center for RBSPICE, and we’re still finding out new things about our near-Earth space environment.  It’s been a great five years, and here’s hoping for at least a couple more.
