Romania's moon balloon dreams draw near! - September 10, 2009
Regular readers of the blog already know of my moon-balloon obsession. It sounds insane but it's not: The idea is to launch a balloon with a rocket hanging from the bottom. Once at altitude, the rocket will fire, carrying a bizarre beach-ball probe on its glorious mission of seleno-Carpathian conquest.
This rocket-balloon trick was briefly tried by the Americans in the 1950s, but it was eventually abandoned in favor of other kinds of rockets that couldn't be blown off the test range by a strong gust (not kidding!).
ARCA is too bold to be deterred by these problems. Yesterday they announced that their first moon-balloon prototype will launch in October. Once again, they're bristling with innovation: Rather than working with costly staging systems of the sort that keep causing Korean satellites to crash, the Romanians have a plan. They're going to tie the second and third stages to the first with a bit of cable. Once the first stage is done, they'll cut the cable and fire the second. When that runs out, they'll cut the cord and fire the third! If you're in doubt about whether this can work, ARCA has created another incredible video for you to watch that shows just how it will happen (see below).
Once again, there is some method to this madness:
The team hopes that the dangling weight of the second stage and payload behind the first will help to stabilize the rocket and keep it pointing straight away from the earth. Assuming all goes well the Romanians will launch a suborbital probe from the Black Sea next month.
Joking aside, there is something about the wacky sincerity of ARCA's plans that makes me really hope this works. I'm very excited to see what will happen!
