SpaceX's Dragon Module Successfully Re-Enters 156

Zitchas writes "Following the news of SpaceX's Falcon 9 rocket with a Dragon module on-board, and its arrival on orbit, we now have the news that is has successfully re-entered the atmosphere and splashed down in the Pacific. As their website proudly claims, this is the first time a private corporation has recovered a spacecraft they orbited, joining the ranks of a few space nations and the EU space agency. A great step forward for space travel. Hopefully everything continues to go well for them."

    Double-check your facts. It's helium-3 that's in abundance on the Moon, not tritium. Helium-3 is a byproduct of tritium decay. Tritium has a short halflife and doesn't accumulate over geological timescales.

    Tritium can be manufactured on Earth. Future fusion reactors (at least the magnetic confinement type, like ITER), will almost certainly test or operate lithium breeding blankets that'll produce tritium in abundance, and it'll hardly be worth millions of dollars a kilogram to ship a bulky product all the way back to Earth.

    Plus, they have the advantage that they are bound to protect you. In the US, the Supreme Court has ruled that police have no duty to protect any individual, only "society," a few special people, and those imprisoned by them. Even if you have a restraining order that commands the police to take action, you are not considered special enough. (See Warren vs. DC, Hartzler vs City of San Jose, Riss vs. New York, DeShaney vs. Winnebago County Department of Social Services; there are plenty of other)

    Our scientific missions seemed a lot more important and interesting on the moon with Apollo 17 in 1972.

    The moon landings weren't really about science, they were about engineering and national pride. The Russians launched the first satellite, the first man in space, and the first man in orbit; we needed to beat them to the moon and prove that we could keep going there.

    We've gotten far more and better science with unmanned space missions.

    The summary seems to indicate that there is an European Union (EU) space agency. Although many members of EU are members of the ESA, not all EU members are members of ESA, and there are members of the ESA that are not members of the EU (Norway and Switzerland).

    The cheesy cargo was a wheel of LeBrouere and was a nod to Monty Pythons skit "Cheese Shop".
