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.

[Pyromanik]

Sounds legit.

Here I was thinking that Kop was going to Mars in 30 days.

*Sad Face*

Anything with a fusion engine in it is awesome.


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

[Apostrophe Spacemonkey]

30 Days is nothing, took me that long to get to work this morning.

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.

'propellant mass out at 30 kilometers per second'....if that ever became uncontrolled, it won't but one can dream ?  might need to invent inertial dampers at the same time

This sounds cool.We are overdue for a space exploration breakthrough.They will probably turn it into a gun first though.

[Retardobot]

For some reason I have compelling-want to launch rubber dicks into outter space.

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.

[Apostrophe Spacemonkey]

We started riding to space on top of missiles designed to explode other countries.

Anything sounds safer then that.

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

i can see the headlines now

they might need to get this up and running before a manned Mars shot takes place, still might be a one way trip.

'...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. '

[Apostrophe Spacemonkey]

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".

[Bounty Hunter]

I wonder if it takes into account the specific shielding the rover had compared to what a human would have (water walls etc)

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

[Pyromanik]

I wonder what 10 mins standing next to the sarcophagus in modern day would get you?

[Kopfjaeger]

i lol'd at the bananaphone

[Black Heart]

Am i the only one to see a downside to using solar panels to power space ships ?

There is no downside in space.

[PrinceTuiTeka]

Except range? Though I think it will be a while before we are venturing that far out of the solar system.
