Skip to comments.This New Fusion Engine Will Cut The Travel Time To Mars Down To Six Weeks

Brace yourselves: Researchers at University of Huntsville in Alabama say they are using "Dilithium Crystals" in a new fusion impulse engine that could cut the travel time to Mars down to as little as six weeks, not the six months it takes now. Txchnologist, an online magazine sponsored by General Electric, talked to team member and aerospace engineering PH.D. candidate Ross Cortez, he said "The fusion fuel we're focusing on is deuterium [a stable isotope of hydrogen] and Li6 [a stable isotope of the metal lithium] in a crystal structure." "That's basically dilithium crystals we're using," he said (Snip) The

We can pay for it with Obamamoney.
Star Trek is right again.
Full Impulse POWAH!
So at which end of that trip is the dirt redder? Mars or Huntsville?
Mars!? I HATE Mars!
Total recall mars landing
Now we have to figure out how to slow it down....
Six weeks - still would need a lot of movies or ebooks.
Look for the Plains of Mars soon to be littered with catalogs from Pottery Barn and announcements of winnings from Publisher’s Clearing House, while your first class letter languishes somewhere outside Peoria.
Planetary Aero-Breaking as in 2012 Space Odyssey might work.
Dilithium crystals have a history of being very short lived. You don’t want to be stuck out in space without extras. It’s not like there is a Harry Mudd on Uranus out there.
That’s quite a tecnological advance.
Now on to the next challenge:
How to slow down to a stop from 50,000 mph without turning the humans into grease spots on the bulkhead.
Any progress on transparent aluminum?
"Time for a little Rock and Roll!"
Your mother told me there was no Harry Mudd on Uranus.
Actually about 6 months ago. Just Google it...
Y’know, that just might be hairy mud but I can’t for the life of me understand the reference to uranus...
Transparent aluminium has been in use in armoured vehicles for several years.
Isn’t that treaty that prevents us from putting nuclear powered thingies into space still around?
Start braking a little over half way there?
But yeah, my first thought was how many G’s would it take.
“How to slow down to a stop from 50,000 mph without turning the humans into grease spots on the bulkhead.”
Accellerate at 1g half way there and decellerate 1 g half way back (or whatever the ratio is), minus whatever speed is needed to maintain stable orbit at Amrs.
how long does it take to travel 64,000,000 in a ship capable of accelerating at 1g assuming the maximum acceleration is used, then:
1g = 32 ft / s^2
1g = (32 ft /s^2)(3600^2 s^2/hr^2)(1 mile/5280 ft)
1g = 78545 mile/hr^2
64,000,000 = 2 * 32,000,000 (because you spend half the time accelerating and half the time decelerating - otherwise you get there, but you can’t stop)
d = at^2
t = sqrt(d/a)
t = sqrt(32,000,000 miles / (78545 miles/hr^2))
t = sqrt(407)
t = 20.2 hr
Double that and get 40.4 hr, or just under two days.
That was an amazing article on transparent aluminum over at HowStuffWorks.com. I had no idea that Star Trek item had already come true. I am afraid to ask about the tricorder. BTW, the HowStuffWorks site really pulls you in and one article leads to another and I was engrossed for several hours!
