I hosted the Nebraska AAPT meeting at the Institute for Culinary Arts on the MCC Fort Omaha Campus.
Michael gave a talk updating the group on the high-altitude ballooning program.
Representatives of the Nebraska Center for Materials and Nanoscience demonstrated some of their educational kits.
We toured our Fab Lab and saw some of the new things they have produced.
We also got to make some custom dog tags with our addresses on them using the CO2 laser cutter.
During our last flight, we lost one of our Go Pro cameras that was mounted to the size of a pod because it likely got ripped off when falling through the trees after it separated from the rest of the balloon and fell from 70,000 ft. I was visiting the Fab Lab at MCC to check on another project and Tom Pensabene, the Dean of IT and e-Learning, asked if I had any projects with the ballooning that might require an engineering solution. He had forged a relationship with a new engineering company and was interested in collaborating on an interesting project. We met with Dane Foster of KuL 3D and a couple of their engineers. They do 3D printing projects and rapid prototyping.
In our discussion, I mentioned how we would like to get better video from the balloon. Usually, we mount a Go Pro camera to a pod and it is subject to the whim of the winds which includes a lot of twisting and tilting. If I watch the footage at regular speed, it is almost enough to give me motion sickness. There are some simple solutions to get more stable video footage, including making a large PVC frame to minimize the twisting or attaching the camera directly to the balloon rather than a pod. The solution we chose to pursue involved purchasing 3 new Go Pro 3+ cameras because of their light weight and a frame that would allow them to take video simultaneously and stitch it together into a panorama in a video editing program.
With their permission, I am able to share photos of the prototype. We plan to do a test launch on March 14, 2015. I think it is a clever and elegant solution and I can’t wait to see test video from it.
We have a busy spring ahead of us. Both Michael and I have given several talks about the high altitude ballooning program recently to various groups and we each have talks scheduled to give in the next couple of months.
The N-HAB group is preparing four launches over the next few months.
We are planning to test a new panoramic Go Pro camera stabilizer on March 14th, 2015. MCC is collaborating with a local engineering firm that specializes in 3D printing to design the stabilizer and, hopefully, we will get some nice panoramic footage at altitude.
My MCC students have started planning their experiments for a launch on March 28, 2015. We hope to launch from the South Omaha Campus location.
We are working with the HALON group at UNO to do a launch on April 14th, 2015 and their engineering students will be sending the live data from the balloon to NASA as a part of a national collaborative event.
We will be doing a workshop and demonstration launch at the Applied Learning Conference in St. Joseph, MO on April 17th.
In addition, my MCC students will be presenting the results from their HAB experiments at the first MCC Showcase from 1-2 pm at the South Omaha Campus Connector Building atrium.

Congratulations to Dr. Dugan and Hastings College on a good first flight and welcome to Nebraska high-altitude ballooning!
As a part of a research project we were planning to do in October, measuring the efficiency of solar cells in near space, we were going to be sent panels from a NASA engineer. Unfortunately, the government shutdown occurred and NASA employees were unable to work. We missed our window of opportunity for the fall launch, but decided to make it a priority for our spring launch.
We received two panels of equal size in the mail this week. One of them is a mass-manufactured battery charging solar panel that costs $20 from Amazon. We expect this to have about 4% efficiency.
The other one is the “latest and greatest” in thin film photovoltaic technology and should get about 30% efficiency. The cost of this small piece is approximately $3000! We will be very careful with this.

Because of the government shutdown, our NASA contact is unable to send us the new high-efficiency solar panel we were planning to test. We are proceeding with the launch, but we will be trying some new instruments and procedures to get the data we are interested in taking.
We will be flying a spectrometer to take spectra, a pyranometer for measuring irradiance, and the voltage and current of some standard solar panels, as well as the usual measurements of temperature, pressure, latitude, longitude, and altitude. We are having a GoPro camera modified to take full-spectrum (UV/Visible/IR) and if it arrives before our launch, we will fly it too.
The NASA Nebraska Space Grant is proud to announce that a workshop for the NASA Nebraska High Altitude Ballooning (N-NHAB) program is open for registration. This workshop will be a 1.5 quarter credit hour course through Metropolitan Community College, equal to 1 hour of semester credit. It is open to college / university students and faculty, and K-12 educators. The workshop’s maximum number of participants is set to 20.
Course Description: This course is a short workshop designed to introduce participants to the world of High-Altitude Ballooning (HAB). It provides the background necessary to design a flight pod with scientific instrumentation, and to participate in a HAB flight to upwards of 100,000ft (19mi) above the Earth’s surface. Students will also participate in the tracking and retrieval of their payload, as well as the analysis of the retrieved data.
To help the student learn the skills necessary to:
1. Demonstrate an understanding of how physical properties can be measured using probes for data acquisition;
2. Demonstrate an ability to work collaboratively in small groups to develop a research question and to solve a design problem;
3. Participate in a high-altitude balloon launch and retrieval of equipment;
4. Analyze data retrieved from balloon launch;
5. Effectively communicate results from data analysis;
6. Prepare for future HAB opportunities.

If you want to read the story of our launch for the Nebraska State Fair Launch on 8/31/13, go here: http://nearspacescience.com/launches/ne-state-fair-83113/
Tomorrow (8/31/13), we will be attempting to tethered a balloon and get photos of the Nebraska State Fair before letting the balloon go. We plan to record temperature, pressure, and radiation data throughout the flight as well as cameras. Unfortunately, the weather forecast predicts that it is going to be very hot again, in the mid-nineties.
We will be launching a balloon at the Nebraska State Fair in Grand Island on Saturday, August 31, 2013.
We will also be offering a High-Altitude Ballooning Workshop through Metropolitan Community College starting Friday, October 4th, 2013 and we will launch on Saturday, October 19th, 2013.
Here are some lessons that we learned the hard way with our High-Altitude Ballooning program.
1. Do NOT turn the chase van off while preparing for a launch.
If you are using the vehicle to power your antenna and computer and/or other miscellaneous devices, it will drain the battery and you will have to get a jump start before starting the chase.
2. Do NOT forget your APRS antenna at home.
You will be dead in the water and have to run and get it which will delay the launch.
3. Do NOT forget to turn on all of your cameras and probes before you launch.
If you turn on the cameras too early, the batteries may run down and they will stop taking photos before you reach maximum altitude. The best way to prevent this is to have a flight list and follow it. Turn on everything inside the pods before you wrap them up and turn on the external cameras right before you fill the balloon, because once it leaves your fingers, there is nothing else you can do.
4. Do NOT count on your cell phone working during the chase.
If you are on the interstate or near a large city, there would not be much of a problem. However, if you go just a few miles out into the country, cell service will be spotty at best. Even with a booster, you are going to run into problems if you rely solely on your cell phone service for some vital tasks.
5. A car GPS won’t cut it.
We originally used the removable GPS from our car to try to find the payloads. Even though it could get us to within 20-30 feet of the correct latitude and longitude, we could still not find the payloads in very tall corn. When we had a good hand-held GPS like the kind used for hiking or geocaching, we were able to walk right to it.
6. Have a plan for feeding the chase team.
If you let a bus full of students stop at a convenience store or fast food place during the chase, you will probably miss the landing. Even if you have packed sack lunches, drinks, and snacks, you will probably need to stop for a bathroom break which will take a while if you have lots of people. If you have a small advance chase team, they could go ahead of the larger group and have a greater chance of seeing it land, making it much easier to find.
7. Have a plan when you get to the touchdown site.
Make the participants take the time to put the coordinates in their hand-held GPS units, have them go in teams, and make sure that one person in the team has a walkie-talkie set to the correct channel. We have had students run off willy-nilly when they hear approximately where the payloads landed so they can be the first ones to find it. Most of them are not used to walking long distances in the heat of summer through corn or down dirt roads. They get disoriented easily and might get hurt walking on uneven ground. If everyone has a walkie-talkie, they will hear when a team finds the payloads and everyone can regroup and if there is a problem, they can get help quickly.
The Nebraska High-Altitude Ballooning (N-HAB) project began in 2011 with our first launch through a workshop hosted by Metropolitan Community College and NASA Nebraska Space Grant. Since that time, we have been a part of dozens of high-altitude balloon launches in the state.
This blog was created to have a journal of our flights, a repository of ballooning data and images for teachers and students to use, and a place to discuss techniques for facilitating scientific inquiry.
