The Spacefleet Project
• Spacefleet aims to take part in the “space tourism” market
• It is a market that is set to be worth billions of dollars per year
• So far, $20M has been spent by three well-heeled men, taking vacations on the International Space Station.
• There are other developments in progress

What is “space tourism”?
• It is travel and sightseeing in space by paying passengers.
• It can be divided into two sorts – of differing experience and cost: “sub-orbital space tourism” and “orbital space tourism”
• (In the remoter future, lunar travel will be added, no doubt – there are already plans)

Sub-orbital space tourism
• Total flight time ~ 45 minutes – 1 hour
• Stupendous view of the Earth from 100km altitude
• Zero-G of duration ~5 minutes• Seat cost ~$200,000• (Futron Report cites the view of Earth
as the single biggest attraction)

Orbital space tourism
• Total flight time not less than ~ 2.5 hours for a single orbit – probably up to 5 hours for, say, three orbits – unless visiting a space station
• Somewhat higher view of the Earth and zero-G duration not less than 1.5 hours
• Cost per seat ~ $500,000 for sightseeing orbits, rather more for a stay on a space station

The Spacefleet Project
• Space tourism is a reality now• VG has 38,000 prospective customers• VG has $10M in advance fees ($250,000
each)• Futron Report estimated 1000 passengers
in 2008-9• Three people have paid $20M for a trip to
the ISS• Futron assume sub-orbital flight ticket cost
from $100,000 to $250,000

The Spacefleet Project
• The potential market will be at least as big as Futron predict, so there is a market for 1000 flights in 2008-9
• VG will not be able to fulfil the demand
• There are only a few others who will be able to pick up the remainder
• SF could produce a (sub-orbital) craft to fly in 2010

The Spacefleet Project: SF-01
• The SF-01 is a rocket-powered lifting body
• Vertical or ramp take-off• Runway landing• Three passengers, two crew• Flies to >100km• Glides back to land• Est. development cost: ~ £35M

The Spacefleet Project
• Spacefleet Ltd. intends to build a sub-orbital craft, because it is a relatively easy introduction to space flight and the market is assured
• A sub-orbital craft requires ~ 4% of the energy necessary for orbital flight and does not need high-quality thermal shielding
![Page 15: The Spacefleet Project Space tourism and transport Dr. Raymond D Wright MD, Spacefleet Ltd](https://reader036.vdocuments.us/reader036/viewer/2022062315/56649d985503460f94a82637/html5/thumbnails/15.jpg)
The Spacefleet Project
• If successful with sub-orbital flights, SF intends to continue on to develop an orbital craft of similar overall design – better heat shielding, more powerful engines
• By the time we can achieve that, there will probably be a space hotel, perhaps by Hilton!

The Spacefleet Project
• Beyond orbital flight, there is the Moon for which a new craft, shuttling between Earth orbit and the lunar surface would be designed
• There is no limit to the follow-on projects that could be considered, and the revenues that could result, once a start can be made, with sub-orbital flight
