University of North Dakota High Altitude Balloon Project
Future projects:
Technical:
- A command receiver will be added to the package to act as a backup to automatic
control of the cut-down mechanism.
- Ultra-violet light flux meter.
- Electric 'field mill' to measure the earth's electric
field at altitude.
- X-ray scintillation detector to measure radiation levels.
- ATV video camera/transmitter to capture real-time images
of the ground, horizon, payload, and balloon.
- Steerable parachute to allow the gondola to activly seek a
designated landing site.
Logistic/Procedural
- Design and build flight hardware over a longer timeline, with less frantic last-minute
action.
- Establish a better mechanism for communicating with our amateur radio chasers
and monitors. In the past, calling a mission off at the last minute has lead to
confusion and annoyance to many folks. We will try to avoid this in the future.
- Establish a fixed control station in a high location (Space Studies Dept.,
5th floor of Clifford Hall). Using a mobile control station has proven problematic.
- Keep the web page better up-to-date. The web page is our backup communications
channel with hams and monitors.
- Make better design decisions. Having more leadtime will help avoid throwing
together kludges at the last minute to get the thing airborne.
Outreach/Education:
- We are working with both the
UND Electrical Engineering Dept. and the Upper Midwest
Aerospace Consortium on a project involving a satellite design course. The course
teaches EE students spacecraft design concepts through hands-on designing and building
of hardware and software. While launching actual spacecraft is still a ways off, our group
is providing access to the near space environment for student-built payloads.
- Members of our group recently made a trip to Rosebud, South Dakota, to give presentations
at three Native American schools. We brought a recovered gondola from
Flight 2000-1, a videotape of highlights of our previous
missions, radio tracking gear, and other flight hardware. Our goal was to show how near-space
research could be done on a budget, and to try to get people more enthused about science.
We also did two tethered balloon flights lofting a camera-only payload, and released
three 300g balloons with messages attached to them. The trip went very well, our hosts
from
Sinte Gleska University
were very gracious and accomodating, and everyone had a great
time. A report on the trip is
available online.
Our intent with this project is to start out small and build on the knowledge gained by each
mission. It is far too easy to get carried away and design a payload that is heavy, complex,
expensive, and will take far too long to build. By building on things slowly, we hope to identify
and avoid major pitfalls while learning more and just plain having fun.
