Please use this topic to discuss Space Adventures plan to send two clients a professional cosmonaut pilot on a privately-financed Soyuz mission around the moon. |

Wonder if any of the Apollo astronauts have bought a ticket. It doesn't say how many orbits they will make. |

The mission does not enter lunar orbit. It is a circumlunar "free return" trajectory. |

And what about the Soyuz heatshield? Can it withstand a higher speed reentry? I'm also assuming that a test flight is being planned - I wouldn't want to pay $150m for a ride aboard a space system that hasn't been tested before... |

Space Adventures has said there will be tests leading up to the flight, including the possibility for an unmanned flight. RSC Energia, funded by Space Adventures, completed the engineering studies for the mission and have said there would be modifications needed to the Soyuz but they would be based on prior flight-tested designs. |

I would want to read the fine print on the contract. What happens if at any point the mission fails to make it around the moon? Do you get another flight attempt? A partial refund? I've done some "high-risk" things in years past, and my contract usually stated that once you get started, you pay, unless it was something out of your control. |

Space Adventures' reservations are nonrefundable. However clients who purchase seats to the space station have the option to purchase travel insurance to protect for re-flights due to technical or other problems. I would imagine a similar policy would be available for this circumlunar mission. |

Seriously, if they still have the baseline data from the unmanned Zond flights from the 1960s, and can modify/adapt the existing Soyuz TMA spacecraft, then it would be an interesting proposition. The only question remains, would they use a Proton launcher or maybe an Ariane 5 rocket? And launch from French Guiana if they do? |

The plan as I understand it is for a dual launch, both to originate from Baikonur, with the Soyuz launching with the crew as normal, followed by a propulsion module to launch on a Proton. |

I don't believe the facilities being built in French Guyana are intended for man rating (no Soyuz processing facilities or astronaut housing for instance), although technically that would not be too hard a hurdle to overcome. Sounds to me like they would just use the R-7 booster since the Proton has never been 100% man rated and its hypergolic propellants mean it typically doesn't get used unless it has to.While technically it is feasible to just revive Zond's configuration for this flight, the g forces experienced by the returning craft were horrendous and I believe some information said a man might not have survived (living tissue did since they were bio flights, but it was cells and turtles if I recall correctly). As such, if the onboard computer's controlled reentry mode fails, it could be a bone crushing ride (more so than the recent Soyuz TMA reentries that went ballistic) due to the speeds the craft has to slow from. |

Unlike ISS/Soyuz flights, this is a mission that really pushes the spacecraft to the limits of the Soyuz design. I may be wrong but from what I have read the Russians had some serious issues with their unmanned Zond programs on circumlunar flights. Mainly with reentry. I am sure the current Soyuz is a much better spacecraft, but as I said this would really push the capabilities of the Soyuz spacecraft and to test it more than once or twice would really run the costs of the manned commercial flight even higher. |

Originally Soyuz spacecraft was designed for circumlunar missions. |

Yes, Soyuz was designed for lunar missions, but they never did fly the spacecraft manned. The Zond missions apparently suffered from re-entry problems that would have killed the crew they been manned flights. I think my point was that unlike ISS missions, which Soyuz has flown countless times, a manned circumlunar flight has never been done before by the Russians and would really be pushing the spacecraft beyond its known limits. I am not saying it could not be done. I would like to see them try. I'm saying that without proper flight testing it would be very risky. |

Space Adventures has said it now has two customers for its proposed private circumlunar mission, but it will require major changes to the Soyuz spacecraft, Spaceflight Now reports. Speaking to the National Space Club Florida Committee on June 10, [Space Adventures president Tom] Shelley said Soyuz contractor Energia plans to modify the spacecraft for the moon mission by changing the ship's communications and navigation systems."We are going to have to change the heat shield because you're re-entering at a significantly higher speed" on a lunar mission, Shelley said, adding engineers are considering whether to guide the Soyuz landing capsule to a "skip re-entry" in which the spacecraft would dip into the atmosphere to dissipate speed before plunging to the surface to a parachute-assisted touchdown. The Soyuz also needs a new habitation module to give the crew more living space during the week-long trip from Earth to the moon and back. According to Shelley, the earliest a mission could launch would be late 2017, but that would be "a very aggressive schedule." Shelley described the two depositors as "independent customers" who booked their flights separately. He did not disclose the identities of the clients. |

Flying into space can be compared to climbing Mt. Everest. The novelty wears off a bit when anyone who is rich enough can do it. |

Boy, that will be a great day (as per shuttle astronaut Joe Allen, who wrote about the day when astronauts will be regarded as routine travelers). |

Given the new heat shield that would be required, I think I'd want a test flight before the vehicle I go up and back in. |

Given that the Soyuz was designed for lunar missions, why can't they fly the Soyuz around the moon, brake in Earth orbit (using a skipping trajectory) and then descend as a usual Soyuz flight, obviating the need for a new heat shield? |

Why couldn't they do a braking burn into earth orbit and circularize into a stable orbit first? Can the Soyuz generate enough Delta-v to slow down? |

Dwayne Day, writing for The Space Review, discusses a lawsuit that reveals the identity of Space Adventures' first circumlunar mission client. Late last year we suddenly learned a lot more about what had been going on when Harald McPike filed a lawsuit in the United States District Court for the Eastern District of Virginia against Zero-Gravity Holdings, the renamed Space Adventures. McPike, it turns out, was the first customer for the circumlunar flight, the one who signed up in 2011 to pay $150 million for the trip. Those who follow spaceflight news closely, particularly any news about space tourism, will probably respond to seeing McPike's name by scratching their head in puzzlement. He is not somebody who was well known, or even known at all, in any of the space tourism discussions. He has not sponsored any space events or appeared as an investor. He is not famous. But, apparently, he is very, very rich.McPike is, according to a district court document, "a private investor and adventurer who hails from Austria, but currently resides in the Bahamas. In the past, plaintiff has undertaken expeditions to the North and South Poles and has scaled many notable mountain peaks including Mt. Kilimanjaro. He now wishes to add space travel to his long list of adventures." McPike was not one of the eight people who booked tickets aboard a Soyuz spacecraft to the ISS. But he certainly had ambition, wanting to fly around the Moon, and he had the bank account necessary to buy a ticket... |

Harald McPike has settled a lawsuit against Space Adventures after spending two years in litigation trying to get his deposit back. What the two sides ultimately decided is unclear. The settlement finalized in April is sealed; each side agreed to pay its own legal costs but would not comment further on whether money changed hands.Space Adventures is still pursuing its planned moon trip. On its website, the company promises that "if you chose to join this Circumlunar mission you will see the illuminated far side of the Moon, and then witness the amazing sight of the Earth rising above the surface of the Moon." |
