Discussion Overview

The discussion centers around the accessibility of commercial spaceflight for the average person, exploring the feasibility, costs, and safety concerns associated with private space travel. Participants reflect on the current state of commercial spaceflight, potential future developments, and the economic implications of such ventures.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants express excitement about the possibility of private spaceflights, suggesting that a suborbital flight may become affordable in the next couple of decades.
  • Others highlight the rising costs of energy and speculate on the affordability of space travel, noting that current commercial payload costs are high, potentially making space tourism inaccessible for most people.
  • One participant mentions that while SpaceShipOne marked a milestone in commercial spaceflight, it does not equate to sustained orbital travel, emphasizing the need for safety improvements before public access can be considered.
  • Several participants discuss the costs associated with different types of spaceflights, estimating prices ranging from $200,000 for suborbital flights to several million for orbital flights and stays in space hotels.
  • There are claims that spaceflight could be cheaper than current estimates, referencing historical designs like the Sea Dragon rocket, but concerns are raised about the safety and practicality of such designs for human space travel.
  • Some participants question the fairness of comparing historical costs to current prices, arguing that human-rated launch vehicles are inherently more expensive than those for unpressurized payloads.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the accessibility of commercial spaceflight. While some are optimistic about future developments, others remain skeptical about affordability and safety, indicating multiple competing views on the topic.

Contextual Notes

Participants acknowledge limitations in the discussion, such as the dependence on economic conditions, safety standards, and the evolving nature of technology in space travel. There are also unresolved questions regarding the feasibility of proposed costs and the implications of historical comparisons.

After watching the new series on the Discovery Channel "When We Left Earth" and "The Dark Side of the Moon", I became enthralled with the majesty of orbiting above Earth with a front row seat to the cosmos as a back drop. So, when will private spaceflights be possible for an average person? Just to go up make a few orbits and come back down would be spectacular and once in a lifetime experience.
 
Astronomy news on Phys.org
With the price of energy rising and the supply of hydrocarbons per capita on the decline, a better question might be how much longer the ordinary person will be able to afford to drive to the store using gasoline.

As to getting to space for say a Low Earth Orbit excursion you might want to consider these costs. The source cited below suggests that commercial payload costs are averaging $3600-$4500 per lbs.

These numbers look like they come from this citation:
http://cost.jsc.nasa.gov/ELV_INTL.html

Unfortunately these numbers seemingly predate $20/ bbl of oil (2001) and while these vehicles don't exactly use gasoline you can likely expect that fuel costs for lift off have some correlation with overall energy costs.

Using a figure of $15,000 per pound and multiplying by your weight, I'd suggest that if this is less than your equity in your home, then you just might be able to afford to go on a LEO tour.

Then of course there is the cost of getting back that is not at all accounted for. Oh well, so the kids will need to get scholarships.

Not in our (or, at least, my) lifetime. But if we're lucky, the price of a suborbital straight-up-and-down shot might be affordable in the next couple of decades.
 
Two articles about commercial space flights.

"SpaceShipOne cracked the barrier to manned commercial space flight in June by flying 328,491 feet, or about 62 miles, above Earth — about 400 feet above the distance scientists widely consider to be the boundary of space. The flight lasted 90 minutes."

I watched something on Discovery about this. I think its kind of like a jet that takes off from a landing strip rather being launched. Expensive airfare though, 208,000$ that should take care of energy costs. Doesnt look like its going to make a few orbits on flight but I am sure you get a damn good view of the cosmos at a height of 62 miles. However for 208,000$ you probably don't even get to experience zero gravity. Anyways looks like commercial space crafts will be available in my lifetime, will i be able to afford it in my lifetime? Probably not :(
 
Actually seems a bit of a bargain the way petro prices are rising recently.

I wonder would that 208,000$ include refreshments and an in-flight meal?
 
While Spacedhip One was a great feat by a civilian company, it is nowhere near being able to put something into orbit and stay there. Spaceship One was the equivalent of throwing a rock up in the air and having it come back down. No disrespect intended to Mr. Rutan, but please put his achievement in perspective.

Space flight like you are talking about won't happen in our lifetime. The cost is prohibitive (of course) but the safety issue will still have to be addressed. There would not be any kind of transport available to the general public until it has a margin for safety equivalent to current air transport.

You experience several minutes of freefall.
 
Commercial plans by various private corporations include
  • $200,000 or so for a suborbital flight.
  • A million or so for an orbital flight.
  • Several million for a stay in a space hotel.
  • One hundred million to fly around the Moon.

These ventures obviously are not targeting the "common man". They are looking for ways to help make the wealthiest people just a little bit less wealthy.
 
Space flight can be a lot cheaper than that.

http://en.wikipedia.org/wiki/Sea_Dragon_(rocket )
"The rocket would have been able to carry a payload of up to 550 metric tons into low Earth orbit. Payload costs were estimated to be between $59 to $600 per kg, which is much less than today's launch costs. TRW conducted a program review and validated the design and its expected costs, apparently a surprise to NASA."

Emphasis is mine.

Comments:
  • It is not quite fair to compare 1962 dollars to 2008 dollars.
  • It is just plain wrong to compare the cost of getting unpressurized payload to orbit to the cost of getting humans to orbit. Human-rated launch vehicles are inherently a lot more expensive than simple launch vehicles.
  • That design has two huge single points of failure -- the single thrusters on the first and second stages. No astronaut, let alone a millionaire, would ride such a beast.
  • My list in post #8 is about commercial ventures. None of these ventures is considering using vehicles built by traditional NASA launch suppliers.
