what could possibly go wrong, except maybe having to survive a 10G assault every 30 mins for a month

The resultant microsecond reaction forces the propellant mass out at 30 kilometers per second, and would be able to pulse every minute or so and not cause g-force damage to the spacecraft's occupants.

Sounds like an episode of Star Trek.

Where is Kop getting this 10G every 30 mins nonsense from?

That's what I'm trying to work out...it doesn't state any accelerations goes on to say:

"...not cause g-force damage to the spacecraft's occupants."

and then explains that it only takes 3 days to speed up and slow down (which is cool that it doesn't aerobrake)

What with the talk of grabbing an asteroid it looks like we're finally seeing a shift towards true space exploration.

Can we make this happen?

Yeah so if you imagine 150 tonnes, and a bunch of ball bearings right, and each ball bearing accelerating up to 30 km/s contributes a small amount of force to the 150 tonnes (due to newtons 3rd), so you control the number of ball bearings that are allowed to accelerate and you control the acceleration of the 150 tonnes, up until just less than 30 km/s

If it did become out of control you would have what we call an explosion, and even classic rockets are more than capable of those.

Anything sounds safer then that.

As long as they're big enough to see from the ground.

'...astronauts would receive a radiation dose of about 660 millisieverts during a 360-day roundtrip flight, the fastest travel possible with today's chemical rockets.'

'An astronaut living for six months on the International Space Station, which flies about 400 km above Earth, receives a dosage of about 100 millisieverts. '

Post by: Apostrophe Spacemonkey on May 31, 2013, 02:55:06 pm: That is a round trip flight. One way would be half that.

The stuff article title (as usual) is misleading, it would increase the chance of fatal cancer about 5%, still pretty high, but I wouldn't phrase that as "likely to kill you".

Stupid stuff, with their stupid titles, and the stupid people in the comments fuck me off too.

There is no downside in space.
