Ballooning

2

- Started at Space Grant June 2000

- Was a student at Space Grant 1990-1995

- Programs had advanced

- Hard for freshman students to get plugged in

- Sink or Swim

Origins:

3

How it all started…

- Western Regional Meeting in San Diego Fall 2000

- Bob Twiggs introduced CubeSats

- Great concept but…- 80 to 100 new students a year- $35K to $50K- Complexity

- Seed was planted

Origins:

4

What if students could get close to space?

- Met Edge of Space Sciences (EOSS) in Fall 1996

Origins:

5

- Promise of recovery and 100,000 feet

- Price was right

- Many launches every year

- Some of the same engineering challenges

Origins:

6

With the combination of these items, BalloonSat was born

Origins:

7

- BalloonSat is an excellent, low cost platform for “Crawl” level student missions to the Edge of Space

- A BalloonSat weighing up to 9 kg can reach 30 km (100,000 feet)

- Students faced with many engineering challenges- Mach 1, -80 C, near vacuum, impact and burst

- No microgravity but BalloonSat can be recovered

- Ballooning is inexpensive- Helium (~$80)- Balloon (~$150)

- You mostly control launch

BalloonSat Uses:

16

- BalloonSat is geared to college level freshmen of all majors but high school students have done it too

- Taught every semester as part of a class titledGateway to Space

- Students are placed in teams of six and given an RFP and write proposal

BalloonSat:

17

- Atmospheric radiation levels

- Solar cell efficiency

- Atmospheric soundings

- Video imaging

- High altitude effects on

roaches

- Digital sound recording of

upper atmosphere

- Temperature studies

Past Student Experiments:
