ICAN-II by SMPritchard ICAN-II by SMPritchard
I made this model to accompany a blog post I'm writing for Icarus Interstellar.

ICAN-II was an idea for an antimatter powered manned spacecraft that was developed at Penn State University (a university I will be attending in the fall) in the 1990's. The original design was intended for manned travel to Mars, but calculations were performed for a round-trip voyage to Jupiter and a no-return mission out to Pluto. The flight time from Earth-orbit to Mars was just 30 days and required only 30 nanograms of antiprotons to initiate the reaction, as well as 362 metric tons of reaction mass, provided by a spherical shell of silicon carbide.

Beautiful work! Would you like to contribute an image or two to my Beyond Apollo blog? Can't pay - they barely pay me, it's a hobby, really - but could get you some more exposure (never a bad thing). [link]

Thanks! Sure thing! I'd love to.

Excellent revisualization of the lackluster original. IIRC that antiproton-catalyzed microfission had a specific impulse that was a whopping 13,500 seconds. Blows a NERVA right out of the water.

Thanks! It was certainly an impressive design. Hopefully one day we can build one.

Do I see Bigelow modules?

Could be TransHab modules (which were licensed by Bigelow).

And it was never built...stupid Earth monkeys.
The only way to develop cost effective technology is to continue generating it.

Well, it wasn't built because the technology just isn't there yet. We can't store antiprotons long enough for them to be useful in spacecraft, and the traps themselves would have to undergo extensive testing to ensure they could survive launch. The study was only a brief overview of how such a propulsion system might one day work.

Yeah, I know.
Keep at it and one day, the tech will be there.
Trouble is humans want instant gratification; if they can't make a quick buck right away, they lose interest.
