AAE 450 Spring 2008
Balloon Cost
Propulsion
Launch vehicle mass 500kg 1000kg 2000kg 3075kg
Cost of balloon launch (Helium) $58,000 $96,000 $172,000 $254,000
Cost of balloon launch (Hydrogen) $57,000 $95,000 $169,000 $249,000
Aircraft Cost (White Knight) Maximum payload of 3075kg Altitude = 15,000m Price: $25,150
Notes: Breakeven height increases with gross weight (32,133m at 3075kg)Minimum breakeven height (500kg) is 27,000mCosts rounded to nearest thousand.

Possible additional costsAircraft Insurance, $600,000/year, $50,000/month Existing ground station will not suffice for orbital launch
Future Work Integration with other codes Output tensile force for Structures Further refining costs
Balloon (in constant cost regime, 3,075kg) Tugboat standby: $1,000/day, 2 weeks = $14,000 Tugboat insurance: $4,000 Tugboat operation: $12,000/day, 2 days = $24,000 Total: $42,000
