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.






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.


“…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.

Of Rockets, Alligators, and Baby Sea Turtles

I recently had the amazing opportunity to go to the Kennedy Space Center as an invited guest to see the launch of a pair of spacecraft, the Radiation Belt Storm Probes (RBSP). This opportunity came to be through my position as a researcher at Fundamental Technologies, a small research firm in Lawrence, KS that will be the Science Operation Center (SOC) for the Ion Composition Experiment (RBSPICE). This was my first, and likely only, chance to see a launch as an invited guest, and my wife and I were over-the-moon excited, if you’ll forgive the pun.

Unfortunately, the launch was delayed 24 hours from its originally scheduled launch time of Thursday, 08/23 at 0407 EDT because of a concern over the RD-180 engine on the Atlas V that RBSP was atop. There had been a problem with another RD-180 engine that was being fitted to another Atlas V in Alabama, and the engineers wanted to make sure that the same defect wasn’t present in RBSP’s engine. No worries from us, though, since we had reservations through Saturday. Plus, we didn’t mind the fact that we’d get to have a full-night’s sleep after travelling all day long. That evening we did get to attend a reception hosted by United Launch Alliance, the group responsible for providing the launch vehicle. It was your typical cocktail party with everyone standing around awkwardly having awkward conversations, awkwardly introducing people they’d just met to other people they’d just met, while trying to juggle silverware, plate, and drink in one hand to shake hands with the other.

Our hotel was right on the beach, so being a wannabe photographer, I had to go out early in the morning and see if I could get a good photo of the ocean sunrise. When I got out to the beach in the predawn, I was met with a surprise. The spotlights illuminating RBSP’s Atlas V on Space Launch Complex 41 at Kennedy Space Center were clearly visible from our hotel in Cocoa Beach. It was pretty darn cool to be able to see that our spacecraft was there and waiting from so far away. While waiting for sunrise, I also got another surprise photo opportunity. Apparently, August is sea turtle hatching season, and my wife and I got to witness one young, lucky turtle make it from the beach to the sea without becoming breakfast for the lurking sea gulls.

Finally, the day of the launch was at hand! We had tried to go to bed early since our alarms were set for 0030 so that we could get ready and be at KSC to catch the shuttles to the viewing bleachers by 0130. Our plans for an early respite were ruined first by phone calls at 2100, and then by a fire alarm at 2330! Someone had pulled the fire alarm as a prank and woke up the entire hotel sending us all out to the parking lot to escape the ear-splitting alarms in our rooms. So with minimal shut-eye, we headed out to KSC and were at the Banana Creek/Saturn V Viewing Location by about 0200, ready to see RBSP leave the planet. The location was close enough to afford a very cool view of the launch vehicle, but far enough away that we wouldn’t be roasted by the exhaust.

Being right next to a swamp, however, the mosquitoes were vicious! The countdown was approaching the T-4m mark at which there was a scheduled 25-minute hold in preparation for the Readiness Poll for Launch. Once everyone gives the Flight Director a “Go”, then the countdown resumes. We never made it that far. As the various systems were polled for a go/no-go, everyone was good except for down-range tracking. The tracking beacon on the launch vehicle wasn’t holding frequency and the down-range radar couldn’t maintain a definite lock. The launch was scrubbed and scheduled for a second attempt on Saturday morning.

After a couple fitful hours of sleep, it was time to get up again and head back out to Kennedy and the Visitors’ Complex! I volunteered at the RBSP exhibit booth there next to the IMAX theater answering questions about the radiation belts and the RBSP mission, as well as leading youngsters through a variety of short activities we had set up to demonstrate the effects of magnetic and electric fields. It was also a good time to reconnect with some great educators I met at the RBSP Teachers’ Workshop held at APL earlier in the month. My complimentary ticket to the KSC Visitors’ Complex didn’t include access to the bus tour, so no up-close tour of the VAB for me, but they do have a pretty cool Rocket Garden where they have several launch vehicles on static display.

Saturday morning at 0030, it was time to repeat the Friday morning’s routine, thankfully minus the interrupting fire alarm. This time, we made a stop at the doughnut shop for coffee and breakfast. Friday was a struggle without caffeine! The process was pretty much the same as before, show up at KSC and get shuttled to the bleachers and wait. Things were looking sketchy right from the start as we could see lightening off to our south and radar (which everyone had up on their phones) showed a pretty potent cell approaching. It was far enough away that we still had hope that it wouldn’t hinder the launch. At the T-4m hold, though, weather forced a no-go, and it even rained on us for a bit. As the storm cell approached the Cape, the weather conditions became less and less favorable for a launch and once again at 0425, they scrubbed. No launch for us. The night wasn’t a total loss, though. We did get to see an alligator swimming by in Banana Creek right in front of us, and thankfully on the other side of the fence.

On our way back to the airport, we decided to make one last stop at a museum we learned about through a tip on Foursquare, the U.S. Space Walk of Fame. You’d never know it by looking at the front of the museum as it look more likely to house a barber shop than artifacts from the space program, but they have the best and coolest collection of artifacts and memorabilia I think you’ll find anywhere. Many of the folk involved in the space program as engineers, technicians, scientists, and astronauts have donated a variety of gear and equipment including some of the old launch control panels. The coolest thing about the control panels is that they were powered and kids (or space geeks like me) would enjoy throwing the toggles and watching the different systems come to life.

All in all, it was a good experience. I met a lot of neat people, got to talk a lot of space science and geek out, and I at least got to see our spacecraft on the pad and ready to leave the planet even if it never did launch. Of course there was also all the frolicking in the ocean and enjoying mass quantities of awesome seafood and Cuban cuisine. The next launch window for RBSP is on Thursday, August 30th, at 0305, and you can see the launch streamed live on NASA TV. I’ll certainly be awake and crossing my fingers for a fully green board! GO ATLAS, GO CENTAUR, GO RBSP!
