Tito's Inspiration Mars: The Fly in the Flyby Ointment
That is the takeaway from Dennis Tito's press conference Wednesday announcing his Inspiration Mars foundation's project. The ramp up to launch is fast and furious, reckless for a space project of this magnitude.
But, as Tito pointed out, so was the Apollo program. Between 1961 to 1968, NASA went from "How do we do this?" to Apollo 8's historic flyby of the moon. A huge accomplishment.
Tito didn't mention that a flash fire on the launch pad of Apollo 1 killed three of NASA's finest. Seems relevant. With new undertakings of this complexity, the devil is in the detail.
The 2018 target takes advantage of a periodic alignment of our planet with Mars that allows for a rocket to swing within hundreds of miles of the Red Planet and loop back to Earth in a much shorter time and with far less expenditure of energy than would be possible otherwise.
Many known dangers and many unknowns are certainly arrayed against the astronauts. To name a few:
Life support systems will need to be more rigorous and reliable than even those aboard the International Space Station. The project is leaning toward the Falcon Heavy and Dragon capsule from SpaceX as the launch rocket and crew vehicle. While the dragon has been used on cargo voyages the Falcon Heavy, a larger version of the Falcon 9 currently being used, has not yet flown -- a hugely powerful, untested device. The dangers of solar radiation outside the Earth's magnetic field are potentially deadly. Critics of manned Mars missions often point to this single fact as the biggest practical challenge. Many feel Mars will forever remain out of reach as a result. The more optimistic, including Tito, feel the danger can be mitigated. To make the prospect even more daunting the astronauts will not have the advantage of being able to abort their mission. Once it launches and they are under way, the next stop is 501 days later, using Mars gravity as a slingshot for the return trip. Anything goes wrong and they've three choices: live with it, die with it or fix it. Assuming they make it back, descent through the atmosphere will be riskier than usual as their capsule sets a record for manned flight reentry speed.
Sounds ambitious, yes? Requires the right stuff, a disciplined team of hardline achievers, focused engineers, do-or-die warrior-genius adventurers. Do we have that?
Sort of . . . well, no, not really.
Aside from being filthy stinking rich, Tito's biggest claim to fame is being the first tourist in space, paying Russia a boatload of money to be taken to the ISS and back home. So add that to his resume: Was once Extra Baggage.
