We launched!

 It happened all of a sudden and it was amazing. I didn't get to post my other half-written blog posts, but I'll do that later on. 

The science event was ideal - in fact, it was one of the best pulsating aurora events I've ever seen on camera data. Lots of large patches blinking on and off across the sky at three different field sites: Poker (where the majority of the science team was), Fort Yukon, and Venetie. Venetie was the site under the rocket apogee so they were most critical to our launch call. We were on the satellite phone with them and they claimed great pulsating aurora overhead (with faster internal modulations that we were looking for, which likely indicate a phenomenon called microbursts). But we didn't see the camera data showing that since it uploads through an Iridium GO connection and was about 4 minutes behind in time. We dropped the count anyway and as the timer fell, we kept asking: Do you still see the modulations? The answer was yes each time - this was it, the event we were hoping for. When the website finally refreshed to show us what they were looking at, we all cheered. It was indeed a fantastic event, with the fast-blinking pulsating aurora right overhead. 

As the countdown continued we hoped it would last... After T minus zero, the rocket still has about 7 minutes to fly before it gets overhead Venetie. Turns out, the pulsating aurora lasted for over an hour so we had nothing to worry about. 

Beautiful shot by our documentary film crew

As the clock ran down to T minus 1:30, we all raced down the hall and out the second-story door to the catwalk, where you have a direct view of the launchpad down the hill. What a sight to see our rocket fly true, directly through patches of pulsating aurora overhead. 

There were a lot of happy faces that night. I'm glad the doc crew was there to capture it all. Did I mention there was a documentary being filmed for NHK? It might be all in Japanese, except the interviews with us Americans, but they filmed all aspects of the launch and the nights leading up to it. I'll have a link eventually. 

I was carrying my PhD advisor, Marc, around on the laptop through the chaos leading up to launch - showing him the data and being very excited about what was developing. 

Showing Marc the internal modulations Venetie was seeing - notice the clock at T minus 5:37!!

Mike noticed how sublimely happy I look in this picture, even through the mask. Check out the allsky camera display in the background - amazing pulsating aurora everywhere!

We were all so incredibly happy with the result. Sometimes with launches there is trepidation even after the fact: did we hit the right event? Will the data show something useful? This time there were no doubts. It was unambiguously the best case scenario. 

Three awesome lady Co-I's and thumbs up from Marc.

The whole team! Very pleased with ourselves.

The unexpected element of all this was the NHK film crew. I will miss them. They brought fun and novelty to the launch experience and filmed the most amazing footage (some of which will be released to us soon and then I can share). They were all passionate about science and astrophotography and incredibly good at their jobs. Thank you, Reina, Michael, and Justin!!

"L" for LAMP!

It begins

An update on my vertiginous first few days in Alaska so far. I made it to the frozen north on Saturday night (Sunday early morning?) and immediately flipped my schedule to awake-all-night, asleep-all-day. On top of that, I chaired a few virtual conference sessions at odd middle-of-the-night hours (India time zones), did some media interviews with news outlets back home, and tried to keep up with some other hectic business back in Iowa. The lesson is: time gets weird quick if you don't have any anchor points. 

From here, things should settle into a better pattern. I haven't been out to the rocket range yet - that starts tomorrow night. My "days" should look like this: Wake up 2 or 3pm. Walk, ski, or snowshoe and get a couple hours of daylight. Dinner at 5pm either out or in the apartment. Drive to the rocket range at 7pm, arrive by 8. Launch window is officially open midnight to 4am each night. Leave rocket range at 4? 5? to drive back to Fairbanks. Wind down quickly (I hope) and asleep by 7am-ish. 

So far, have done a few quintessential Alaskan things, such as watched moose walking by the highway, fishtailed through multiple intersections (it snowed a few inches last night; it's just the Alaskan way to drive), and visited the Chena Hot Springs for a soak. 

Face in the snow is the best way to cool down briefly before re-immersing in the springs. (Picture from google)

There hasn't been an opportunity for much aurora-viewing yet. The skies have been cloudy or the activity has been low. Last night there was some very decent substorm activity as measured by the GOES spacecraft magnetometers on the nightside of Earth but Fairbanks and Poker were completely clouded over (seems to be the way it goes more often than not). 

See all the spiky bits early on Feb 22? That's the good stuff.

A couple nights ago, my grad student, Riley, caught some good aurora from up in Venetie, 150 miles north of here. He was up there setting up some ground instrumentation, staying in a one-room dry cabin (no running water) so small that the two people stationed there have to push their cots to the side during the day to sit at the table and use their computers. The excitement never ends. I'll leave you with his shot of the outdoor observatory hut and aurora above. 

Into the Dark

 T minus 3 weeks until I leave for the frozen north. Today in Fairbanks, the high is -15°F and the low is -25. Things change rapidly, but that's how I expect it will be most of the time while I'm there. Hopefully everything goes off without a hitch. (If there's a hitch, it's a big hitch, i.e. Omicron.) To boost those chances, the team has an official song and dance to "summon the aurora" and ensure mission success. It's no banana, but it could help. 

A little rumination about the dark. 

I don't think I talked about this back during my Norway travels, but if you don't see the Sun for a couple weeks, it changes you. In 2010, I traveled to Svalbard (an archipelago far north of mainland Norway) for the RENU rocket launch and didn't see the Sun for two and a half weeks. Up there, in the winter, there is no dawn, no peeking over the horizon, just darkness. The sky gets a tiny bit lighter during the middle of the "day" - say the difference between nightfall and full-on night (slight distinction). It was weird and psychologically rough. When I flew off-island on the way home and landed in Tromsø (the Paris of the north!) and saw the Sun rise for the first time in 18 days, I had a near-religious experience. It made me want to compose an epic poem to a Sun God. Or fall on my knees and wail. Instead I think I quietly cried while staring at the Sun long enough that the words "retinal damage" surfaced in my mind. At a time like that, you really get the obsession of ancient cultures with the Sun, the deification, all of it. The Sun is life. 

On the other side of that - sunlight 24 hours a day, which I experienced in the Antarctic summer - it's not such a big deal. You pull the blackout curtains at night, lower the lights, and hang out like you would in the evenings at home. If you venture outside in the middle of the night into the blinding light, it's a bit of a shock, but doesn't mess with your mental state in the same way as no sun. There's not the visceral attachment to the night, as with the daylight. 

Which seemed odd to me, since I've always preferred the night to the day. Given a choice, I'll take the darkness of night over the daylight almost anytime. In high school and through college, all I wanted was to stay up all night and sleep all day. Funny that it's still the sunlight that is most necessary. Something baked into our reptile brains, for sure. 

So. Into the dark once more. This time of year, Fairbanks gets quite a bit of sunlight, I just won't be awake for most of it. Our launch window is midnight to 4am local time, so I'll be sleeping 7am to 3pm-ish. I will be able to catch some late afternoon daylight though, so not the same thing. And I like to think my mental state is healthier than when I was in grad school. We'll see!

Pre-Covid Ground Support Trip

 In December 2019/January 2020, a contingent of the LAMP ground support team and our PI, Sarah Jones, traveled to Fairbanks, AK to deploy and test some ground-based equipment. (Yes, Covid was already coursing through the population, but we had no idea at the time. Later that month, I did a back-to-back trip to Norway as a lecturer for a sounding rocket school and to Bern for an ISSI meeting. Blissfully unaware of the dark days to come.) 

We had several goals for the trip: reconnaissance of the domes at the Poker Flat science building (size, structures for cameras, etc.), testing of a riometer system brought from NJIT (simple explanation is it measures ionospheric density), testing of the USAFA's high-framerate imager in the domes, testing of Japanese imagers, running through the optical and other ground-based measurements we'll have for the launch, and just practicing observing pulsating aurora events. 

Most of the trip consisted of activities like science discussions in the science center's kitchen: 

Real science getting done

and troubleshooting the equipment we brought:

Don and Geoff deliberating

While it might not look like much, it was an incredibly beneficial trip. It helped us cement our launch observing plan, and start to refine launch criteria. We had representatives from the Japanese team able to meet in person with Iowa, Goddard, USAFA and NJIT folks. I feel like we got more done in a week than the months of previous telecons. And of course, not to be underestimated: serious team bonding! 

The group was there over the New Year holiday, so we all trekked out to the University to drink hot cider in the freezing cold and watch fireworks at midnight. Here we are warming up in the museum (https://www.uaf.edu/museum/) just prior to the light show.

This museum is also where I found the dopiest taxidermied bear I've ever seen, almost (but not quite) rivaling Anthony's famous tiger for goofiness. 

Can't get enough Super Golden Crisp

Mostly at my insistence about how much fun we'll have! and how much exercise in the fresh air we'll get!, Hyomin, Geoff, and I rented cross-country skis for the week and went skiing every day before work. Since we worked nights, that meant getting up around 1pm, hustling to ski for a couple hours before the meager daylight faded completely, going out for "lunch" around 6 or 7pm then driving up to the rocket range to work until 3, 4, or 5am. Fairbanks has a community nordic center with lots of different runs including nice hills - man, was the skiing fantastic.  

The place is so big we have to consult the map!

Yeah. Team building. I would also argue that exercising in some way is fundamental to any good scientific research trip, and in the cold, arctic weather this was a pretty good option. (It was literally negative degrees F some days though. Legitimately cold.)

In the early morning hours, when transitioning temporarily to the night shift against your normal internal clock, things can get a bit silly. Some of the Japanese contingent decided to try some extreme-cold-weather experiments one night, like throwing the hot cup of water into the air to watch it turn into a cloud instantaneously. Or (for some reason) leaving a banana outside to freeze and trying to hammer a nail into wood with it. Not sure why that would work. And it didn't. But the banana did hilariously cleave neatly in two during the attempt. Asamura-san decided this was "the lucky banana" for the LAMP mission and asked Sarah to pose with him while clinking the two halves together, an apparently auspicious portent of LAMP's success. 

The lucky LAMP banana

Post-midnight giggles are a thing during overnight campaigns, for sure. We did also manage to capture a fun group shot, complete with banana.

I'll leave you with the legendary Hans Nielsen striking his famous aurora-watching pose: 

I have multiple pictures of Hans in this same pose, spanning different years and geographic locations. 

The LAMP mission: it begins

Restarting the dusty old blog once again to document my current arctic adventures. Does anyone read blogs anymore? 

 A bit of filling in the gaps: My last post to this blog was almost a full decade ago. Since then, I've been focused primarily on data and instrumentation for large satellite missions. But I left a piece of my heart in rockets, and I always wanted to get back to them someday. Academic positions come with a lot of autonomy - yes, must bring in money, must write papers, etc. but in what form, on what topic; that's for me to decide. The current rocket mission, LAMP (Loss through Auroral Microburst Precipitation), is a collaboration between my grad advisor, my grad colleague (slash amazing friend for many years), myself and a few other institutions. The development and launch was delayed a couple years in a row; first, due to an extended government shutdown (anyone remember that one? 2018-2019?), then some kind of global pandemic freakout, I'm not too sure on the details, maybe you've heard of it? And so a 2019 launch became a 2021/2022 launch. Here we are. 

 In the meantime, I've gotten into some other rocket and CubeSat missions. More about that some other time, perhaps. But now - in first quarter 2022 - finally - the LAMP launch is a real thing.

Super high-level overview: LAMP is designed to study a type of aurora called pulsating aurora, which has been so charmingly described by science writer Thomas Mallon as "thin, luminous gruel" (The Last Rocket Club). In a 180-degree overhead view, it normally looks like large splotches of paint across the sky that pulse with some frequency - patches that turn on and off at the same time or different times than neighboring patches. See the faster-than-realtime video example below.

Our understanding of what causes this kind of aurora has evolved over the last few decades. We've seen several breakthrough observational studies since ~2010 that have unambiguously shown a certain type of plasma wave to be responsible for dumping these electrons into the atmosphere. That type of wave exhibits quasi-periodic structures that can be distributed slightly differently in regions of equatorial space, giving this patchy appearance to the aurora as regions of waves dump particles in a regular cadence that is not identical to neighboring regions. Think of a turbulent ocean, with a multitude of waves appearing and disappearing in various patches. What happens out in equatorial space, out in Earth's magnetosphere, connects to what we see in the sky overhead via magnetic field lines that guide particles getting dumped into the atmosphere by these waves. This figure is a decent schematic of the process:

Why do I care? Why does anyone care? Good questions. In this case, I care because I think pulsating aurora, and related precipitation, constitutes a significant or dominant fraction of the energy transfer from the magnetosphere to the atmosphere. Possibly more on this later --- but in general, this energy can cause a chain reaction that affects local levels of ozone and other chemical constituents in Earth's atmosphere. I think we're still fairly lacking in our understanding of this connection, but that's okay - it  makes it an exciting topic to explore. Pulsating aurora contains higher energies (even higher than we used to think) than more frequently studied aurora and it's quite ubiquitous - meaning there's a lot of potential for major energy transfer. My entire NSF CAREER award is based on gaining deeper insights into the cause and morphology of pulsating aurora. 

To prepare for the LAMP mission, Sarah Jones and I and several colleagues and students traveled to Alaska in January 2020 to test ground instrumentation. More about those adventures next time. And then... very soon... preparation and travel to the field for the launch! 

 

Lots of publicity!

For some strange reason, we have had a lot of media attention over this rocket launch. Maybe not enough tragic death in the world for them right now? Who knows. But they latched on for a few seconds. Here are some of the more interesting links:

Pretty good stuff considering NASA didn't publicize this launch at all. (They never do, don't ask me why.)
