Today we had a great opportunity to meet Esther Putman, one of the Brooke Owens Fellows. The Brooke Owens Fellowship Program is an amazing program providing internships and mentors for young women in the aerospace industry. One of the program’s founders, Cassie Lee, works at Vulcan Aerospace and she introduced us to Esther, who is currently interning there. We discovered that Esther had interned at the NASA Ames Research Center, and was part of a team working on the microbiology experiment that we had participated in during last year’s eclipse launch! It was really cool to talk with her about the project that we’d both worked on and to hear about how she worked on it as part of the research center.
We also talked to Cassie Lee and her colleague and learned about how they were using satellites to track illegal fishing boats and the health of coral reefs. It was interesting to hear about how we could use satellites in space to help with our problems on Earth.
This was similar to the company that Esther works at, Space Tango, which sends experiments into microgravity on the ISS. Their focus is using what they learn by experimenting in microgravity and applying it to helping people on Earth. We got to talk to Esther about what she gets to do working there and it sounds like a very exciting job. It was really interesting to hear about how the path she took to end up where she is now and she had great advice for us about perseverance. It was so incredible to be able to meet Esther and hear about her experiences!
Living in Seattle, I see homeless people all around me, wrapped in tarps, sleeping on benches, or panhandling. I can’t even compare my privileges to theirs, and when I think about this, I feel grateful for all the things I have. A year ago, a parent came to speak at my school about homelessness in Seattle. She goes around every year trying to do a count of all the homeless in Seattle. She told us a story of one woman that she met, whose company unexpectedly closed, (she and her husband both worked there) and they suddenly could no longer afford to rent a place in Seattle. This got me thinking, “What can I do to help?”
Since then, I’ve been pondering this question, until we stumbled across the LIHI (Low Income Housing Institute) Tiny House villages. LIHI’s goal is to create tiny houses that homeless people can move into that will provide a stable, weatherproof shelter until they can move on to permanent housing. The eight by twelve-foot house, is covered with a waterproof roof, has a door and a window, and insulated floors and walls. They are safe, sturdy houses that will protect individuals and families and give them a place to call home. To me, this is a great idea, and although it’s not perfect, it’s a good temporary solution to the problem of homelessness and an excellent way to give homeless people a brighter future. The main reason that I would like to build a tiny house is that I want to do something constructive for our community, something that will mean something to someone, something that will hopefully make someone smile. I hope to help someone get off the streets, and get a chance at success in life. The tiny house villages will give people necessary hygiene facilities, access to utilities, and a friendly community. Although the cost of building materials not inexpensive, I think that the end result will be worth it. I’ll come back with new construction and woodworking skills, and the knowledge that I have helped someone find a safe place in a safe environment. After hearing and reading about LIHI’s tiny house villages, whenever I see a person sleeping or asking for money on the streets, I think about the tiny houses, and the great impact that they’ve made, and will continue to make in the homeless community.
On Wednesday we were given a very special opportunity to speak at the Day of the Girl event at the Bill and Melinda Gates Foundation. We were part of a panel with some amazing women: Damaris Toepel from SpaceX, who is nicknamed the “Mother of Dragons” because she works on the Dragon capsule that SpaceX sends up, Dr. Katrina Claw, a Navajo women who is now a genome scientist, and Favour Orji, a second year bioengineer student at the University of Washington (UW). We were honored to be part of a panel with such inspirational women and it was amazing hearing their stories.
We had been practicing and preparing for the speech, and but we were really worried about messing up in front of everybody. On the day of the speech, we got out of school early, and spoke with the organizers and the moderator of the panel, Jennifer McCleary-Sill, who helped us not be so nervous.
When we gave our speech, we went through the whole thing without any memory blanks, which is what we were worried about. It all worked out well. It was interesting to be able to see other people’s reactions to what we were saying and we were relieved that everybody seemed to really like our project. Afterward we had a fun time looking through the various exhibits and talking to people who had really enjoyed our speech which made us feel really good about how it went. All in all, it was a super fun experience even though we were a little nervous, and we’ll always remember the people who were on the panel with us.
We are finally home after a 4206 mile road trip, and 18.5 hours of driving from Wyoming. That gave us a lot of time to digest and talk about our incredible eclipse launch experience, and all the lessons we learned from Loki Lego Launcher 3.0. This is what we came up with on the car ride home.
Don’t make last minute changes unless you test
We were given the opportunity to attach an additional GPS tracker to our payload. We attached it suspended in a gimble (sp) the day before launch. We didn’t think it through all the way and consequently our launcher was unstable and spun. When the balloon burst, the gimble swung and knocked our main GoPro over, causing a large portion of the frame to be covered by wood.
Learn from experts; Mentor others
For this launch, we got to work with the Montana Space Grant Consortium (MSGC) and Sent Into Space, which is a commercial ballooning company from England. Two experts in particular spent time with us: Jen Fowler, the assistant director of the MSGC who organized everything and helped us with all phases of our launch, and Dr. June Wang, an atmospheric scientist from SUNY, who talked to us about analyzing data and calibrating instruments. We learned a lot from Chris and Alex from Sent Into Space, who have done over 300 balloon launches! We hope that someday we could be as great role models to others as these mentors have been to us.
Being part of a team
We felt really welcomed as members of the MSGC team. They helped us in all aspects of our launch, from pre-launch testing, to fill calculations, to providing us with additional supplies, to balloon fill, to the launch itself, to helping with the NASA microbes, to helping coordinate recovery. This launch would’ve been a lot different if it was just our family.
Something that really stood out to us was after a difficult recovery involving a 2 1/2 hour hike through cow pastures and feeling disappointed about our solar panel wire, we came back to camp to people who genuinely cared and understood how we felt about our results. That made us feel warm and fuzzy and supported and we appreciated being part of a team.
Test the simple things as well as the complex
When we recovered we found that one of our solar wires had come loose. When we were testing, we had focussed on the electronics and forgot about the mechanics. We hadn’t checked to see if the wires were all connected. Because of this, we didn’t collect any solar data at all. Next time, we need to check even the simplest things.
Be extra prepared
Ms. Fowler not only taught us a lot but also had a lot of equipment we didn’t think we needed. In previous launches, we’d relied on Internet access to receive our APRS signal. Since we had very limited Internet access for this launch, Ms. Fowler lent us a portable Ham Radio we could use to test our APRS. She had extra helium and extra balloons! It was impressive to see how prepared she was for any contingency.
Equipment failures happen
When we put our data into graphs we saw that our pressure data was completely crazy. Instead of a smooth curve it was jagged and inconsistent, leading us to believe our pressure sensor was faulty.
Also, both of our GoPros turned off well before we ran out of battery. When we looked at the video footage, the GoPros turned off at -60 degrees C, the coldest temperature in all our launches. We didn’t insulate the GoPros because in previous launches we had never reached that temperature!
A straight line is not always the fastest distance between A and B
When we were retrieving our launcher we walked in a straight line towards our landing coordinates. To do this, we had to climb a number of seemingly endless ridges, and only later realized that on the other side of us was relatively flat ground. Our hike back to the car was was a lot faster than the hike in because we walked around the ridges.
Follow your own advice
A few days before launch, we told ABC’s Good Morning America, “Even if something goes wrong, which will happen, just keep on trying.” After we recovered the launcher and viewed the footage and data, we were a little bit disappointed because a few things had gone wrong. When we were reminded of what we had said a few days earlier, we had to laugh at ourselves because we had forgotten our own advice.
We had a fantastic eclipse launch experience, and as you can tell, we learned a lot of lessons from it!
When we were planning this launch, we had two goals:
1. To capture footage of the moon’s shadow on the earth.
2. To capture and analyze data from our flight computer and solar panel as they pass through the solar eclipse.
Well, for Goal 1, here are some images Dad pulled from the two GoPro cameras:
Based on these images, we can conclude that we got footage of the moon’s shadow on the earth. Check for goal one!
However, for goal two, when we retrieved our launcher, we found that there was a wire that had come loose on our solar panel. Fortunately, we had wired it in parallel and not serial, so our flight computer data was still good, but we didn’t get any solar panel data. Consequently it is incomplete for goal two.
Height at highest point (apogee): 29,374 meters (96,371 feet) This wasn’t one of our goals but it was still really cool.
Total flight time: 1:35:42; launch to apogee: 1:10:30; apogee to landing: 25:12. These are our shortest times ever!
Temperature range during flight: -63C to 26C (-81F to 79F). It got pretty cold.
Distance between launch and landing sites: 46.7km (29 miles). It ended up landing in Nebraska!
Distance to hike between car and landing site: 1.5 miles (through ravines and thorny cow pastures) it took an two hours to hike there and back!
Our flight computer data was good. Our launcher made it up to over 96,000 feet, which is more than triple the height of Mt. Everest!
Our APRS data was incomplete because we had somebody else on the same radio frequency as ours. We will want to think about this for future balloon launches when there are multiple launches in the area.
Our GPS data was as solid as ever, thanks to our SPOT Trace. We wouldn’t have been able to find our launcher without the SPOT.
Our solar panel data was disappointing. We didn’t capture any, due to the loose wire. We were unable to measure the impact of the eclipse on the solar power generated, which was a real bummer.
Our Altitude vs Temperature graph showed the curve we have expected, where the temperature drops until the reaching the tropopause, and then it goes up until the balloon bursts. It also reached the coldest temperature on any of our launches at -63 degrees C. (-81 degrees F)
Our Altitude vs Speed graph is very similar to our previous launches, showing the lack of air resistance in the tropopause.
Our Altitude vs Pressure graph is really strange. It should be a smooth curve as the pressure approaches zero, but it starts to go really weird at about 11:51am. It could be a problem with the TP sensor. We may have to try a different sensor for any subsequent launch.
Our GoPro data had some issues too: When we look at the GoPro footage, one camera lasted only 34 minutes and 53 seconds (11:46:53 MT), and the other camera last only 30 minutes 10 seconds. We had fully charged the batteries in both, but after looking at the data both stopped at our coldest point. In addition, we had a mechanical failure of some sort, likely due to the impact of an additional spot that we had rigged above the launcher that collided with one of the GoPro’s at 32:09 (11:44:09 MT) into launch.
One of the first lessons we ever learned from the Loki Lego Launcher is to not speculate, and rely on data. We have learned a lot from the data on this launch. Some of it, we don’t understand (the Temperature/Pressure sensor). Some of it tells us that we didn’t fully check out our wiring (no solar panel data).
Other data confirms that we were able to see the shadow of the moon (visual GoPro data), yay! It also confirms we had a mechanical problem at 32 minutes into launch and our camera batteries don’t work in cold temperatures. However, the good news here is that we were delayed in our launch by almost half an hour. We had originally planned on launching around 10:45am, and we didn’t get the balloon off until 11:12am. Because of that, we were able to get at least a few images of the shadow of the eclipse moving across the earth, hurray!
There are many lessons that we learned, and we are continuing to talk about them as we continue our long drive home (our car ride home always seems to be our mission debrief session). Stay tuned for more lessons learned, and more thoughts on how awesome it is to be part of a scientific team!
9:05pm. We have arrived back at the ranch. We’re tired and exhausted from the 2.5 hour hike through cow fields to retrieve our launcher, but we’re so happy. Not only was the eclipse super awesome, and we were able to successfully recover our spacecraft, but we feel like we belong to the team. The people from the Montana Space Grant have welcomed us from the moment we got here, helped us with everything to do with our launch, and were excited with us after our mission. We’ve learned so much this weekend, and being part of a group of scientists and engineers feels really good. We’re so happy!
6:21pm. Launcher RECOVERED! Had to navigate through several cows, but they got it! A little concerned about our data though, it looks like a wire on the solar panel came loose. We’ll see after we get a chance to review our data. Right now, we have to hike back to the car before it gets dark!
5:57pm. Walking. Walking. And walking. Looks like we’re getting closer.
5:35pm. We are walking in the middle of nowhere trying to retrieve the launcher. Literally the middle of nowhere.
1:08pm. We have landed! It looks like the launcher is on the ground, about an hour and a half drive into Nebraska. We are coordinating recovery operations now.
12:34pm. It looks like our launcher went into Nebraska, but it has now burst and is coming back down, and seems to be coming back into Wyoming!
12:13pm. It seems like there was someone else on our APRS frequency, but we’ve just re-acquired our signal. So far, the launcher is heading in the direction we expected. With luck, we will have captured an image of the moon’s shadow. We won’t start recovery efforts until later.
11:53am We just witnessed totality! What an amazing experience. We’re so grateful to be here with all these incredible people supporting us with the launch and witnessing the eclipse together.
11:17am We have launched! Loki Lego Launcher 3.0 is off! Tracking enabled. Fly, Loki, fly!
11:01am Adding astrobiology microbe experiment.
10:48am balloon fill.
10:36am. First contact! The moon is starting to cover the sun. LLL 3.0 is ready to go.
10:15am. Making adjustments to APRS. Powering on flight computer and GPS units. Anticipate balloon fill in about 20 minutes. Confirming payload weight.
9:16pm. Watching the pros prepare for launch. This beast is a 5000g balloon that will be carrying a six camera 360 degree rig. The girls will be launching a 2000g balloon today. Their previous launches have used 600g and 350g balloons.
7:53am. Everyone up, having breakfast. Definite buzz in the air. Watching the Sent Into Space team start preparing their custom rig; they will be launching first on an enormous balloon. Many folks concerned with the wind.
6:11am – Dad here. Kids are still sleeping, but breakfast is being served for all eclipse ballooning teams. Need to get them up.
It has been a long, hot day at the Fort Laramie Bed and Breakfast, where we have been testing and making final pre-launch decisions.
Yesterday we drove seven hours from Jackson to Fort Laramie, with a stop in Casper to say hi to our friend from Blue Origin, Heather Nelson. When we got to Fort Laramie, we met up with the BBC film crew and headed to the makeshift campground next to the B&B.
This morning we had a very interesting conversation with Jen Fowler, Assistant Director, Montana Space Grant, and also our Launch Director. Instead of an Iridium satellite tracker, we will be using a second SPOT tracker as a redundant tracking system. Ms. Fowler also talked to us about lift calculations, the NASA microbe experiment, and the data from our previous launches. We also talked to Dr. June Wang, an atmospheric scientist from SUNY, who talked to us about the science behind the data we came up with, calibrating our instruments, and waves in the stratosphere.
We also got to watch one of the teams launch a radiosonde, which was really cool because we got to see how their teams did it, how they filled their balloon, how they released their payload, and how they received data. It looks like it was helpful to have a lot of hands helping! We learned so much.
We spent a lot of time testing our flight computer, APRS tracker, SPOT Trace tracker, and GoPros. Ms. Fowler helped us with our APRS by lending us a portable ham radio, which is really interesting to use because we’ve never used one before. We had a problem with Internet access, so the radio was really helpful.
But the biggest problem we found was that one of the wires connected to the solar panel came out of the port, causing the flight computer to not work. We’re lucky we tested today and not tomorrow!
Tomorrow we’re going to launch and we’re super excited! All of our hard work on this project is finally going to come together in a spectacular launch. We hope…. We’re really grateful for the opportunity to learn from and launch with some amazing scientists, balloonists, and engineers from all over the country on this Eclipse Ballooning Project. We wish you all clear skies!
We are heading to the launch site today in Fort Laramie, WY. We may not have great Internet service or any service at all around our launch site. Just in case we can’t update anything, here is our APRS link to follow the Loki Lego Launcher 3.0 on Eclipse Day.
We plan on launching around 10:45 am MT on Monday, August 21. We won’t start recovery operations until after 3pm MT. Right now, our current predictor has our launcher landing in Western Nebraska. We hope it doesn’t land in a corn field, because that would make it really hard to find! For a live feed of a MSGC balloon, also check out http://eclipse.montana.edu
We have had a lot of media coverage the last few days, and we’re very grateful for the recognition. Thank you to Good Morning America for having us on the show, and for asking us to demonstrate the eclipse the next day. Thank you to World News Tonight for choosing us as Persons of the Week. We wish we could have made the opportunities with CTV and Channel NewsAsia work out. We are look forward to working with the BBC on a documentary in Fort Laramie, but that’s all we can talk about for now.
But now we’re focussing on the preparation for the launch; there is so much to do! We need to figure out how to add an Iridium tracker to our Loki Lego Launcher, and then weigh our payload to calculate how much helium we’ll need in our 2000g balloon. We’re excited to meet the other eclipse balloon teams, and the scientists from University of Montana, MIT, SUNY, and more. In addition, we need to figure out how to stay cool for the next three days, because it’s going to be in the 90’s and we’ll be camping in an open field with no shade!
