I start this thread as the old one was sorta learning experience.

This has SRBs to get it to LEO and a one LH2/LOX engine.

In space it will use MPDT drive with 160-200 m2 of 30% efficient solar arrays.

Any comments or questions on this ?

Onme more picture to explain the system and its flexibility concerning the functions.

Yes there is an electric car there too of which a 1/6 scale model has been constructed. :wink:

One more where the MPDT ( magneto plasma dynamic thruster ) appears.

Systems explained.

There is a new kinda developement in MPDT....the NASSIKAS thruster.

Sounds a bit too good tpo be true.

Here is a big minimum craft to Mars. Takes 24 people to LMO and 8 to surface with a 2 seater car.

I corrected the ISP of the MPDT to be what can be found ( I got mixed up with exhaust velocity and ISP ).

It is a bit bigger than shuttle was.

it is still small....compared to physical size of Apollo....and recent Elon Musk designs...like the MCT.

I have changed this a bit...to increase the delta-v with chemical rockets as this has to take off vertically.


This ship can bring 4 people to Mars surface and 8-12 man crew on orbit. It has two cars inside to be operated on Mars.


The carrier mother ship is fully reusable and can launch another ship to Mars in a week. It can also be controlled aerodynamically in ascent unlike the Space Shuttle.


The mothership wingloading of this "THUNDERBIRD-1" at re-entry is around half of what the Space Shuttle had.

Some calculations for the delta V.
