Here is some math to prove that a carrier can lift 17000 kg to 80 km.

——-

Here is how to define the speed of 8000 km/h for the craft at 80 km; http://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line

Take lift equation… ½ x p x v^2 x A x Cl = 0,5 x 0.0001846 kg/m3 x 4937777 m/s x 1200 m2 x 0,5 = 273454 N = ~27000 kg ( 1 % less gravity )

It says 27 000 kg ship doing 8000 km/h with 1200 m2 wing area stays airborne at 80 km when Cl is 0,5 !

Phobos looks really cool; http://en.wikipedia.org/wiki/Phobos_(moon)

It takes at 200 000 km/h speed 22,3 days to get there.

Here is how to get a man on the Jupiter moon..Europa for instance.

Errr…make it MARS MOON Phobos !

How about traditional that goes up like a rocket with 4 kilos of accus alone ?

I have actually been working on these for 7 years and 8 years in 1/2014..to be presice.

Earlier version of the GEKKO aka NorthStar enclosed. NS1 was like a quarter scale of the present 180 seater version….and very primitive I must say.

I expressed 2011 that the Gekko high flying solar passenger ship could carry a space vessel as well.

I realized that if you launch a space ship from a mother ship in FL800 going 4000 km/h you dont have to have the space ship to be extremely aerodynamical since the MS is doing only 150 km/h IAS.

I counted the ship could reach Jupiter’s Europa moon in just 2.4 days. 1/100th of the light speed ( c ) is an enormous speed. It is 10.8 million kilometres per hour ! Hope I got my numbers correct.

I just found out that Rice University has 30% efficient multilayer FILM THIN cells dveloped when I found this…80% efficient !

http://www.ecogeek.org/content/view/1329/

See also this…50% efficiency about to be reached.

http://www.gizmag.com/nrl-solar-cell-50-percent-conversion/25826/

I checked that plane could reach 1200 km/h speed at 20 km/ FL650 and mach 3 at FL750

http://usatoday30.usatoday.com/weather/wstdatmo.htm

Commercial moon flights could be possible pretty soon at very low price !
