    ISP figure corrected...it is 14500 s at its best.

    This is bigger now...a bit heavier than shuttle but smaller.

    If you wanna make it profitabale the tickets must be pretty expensive as the fuel alone ís 6-7 million euros.

    My claim is here. Based on limited amount of calculations.

    Some tuning to get more Delta-V for the LEO with initial booster/mothership.

    You have to do 25 trips to Mars with T-bird 2 ( on send one every week for 5 months ) to get 100 people on Mars like Elon Musk is doing with one shot.

    Aeroplane like design for going to space have been studied.

    Hello!

    Fanny thing happened on this design today. I counted if it could land on Mars.... The mothership...and it could at 200 km/t speed only. As it has 1/3 wing loading of the space Shuttle....and the Mars gravity is just 38%. How come nobody realized this...on fumes it can land on Mars at 100 mph.

    This is a win win situation...even if the mothership crashes a bit the orbiter can sent the lander to pickem 2 pilots up. Plane could have the stuff to start a colony whole 30 metric ton of it. Also the mothership could be a shelter as it is.

    I ended up on this concept. This gives a change to put 52 people on orbit or ISS. Considering that americans pay 70 mio usd to russian per astronaut to get them to ISS the 115 000 € fuel cost per customer does not sound ja too bad does it ? Fuel cost is estimated to be 3% of the expenses in space travel today.

    Nuclear power is obsolete in space; https://www.youtube.com/watch?v=wXiitWK_6Qg

    Isaac Arthus tells us that Zubrin mentioned that 1 kg of nuclear power delivers only 10 watts...when solar panels actually do make 1000 watts per kg.

    Here are my landing strips on the Mars on Holden Crater. These could be checked with the faster ships klander and 2 electric cars and then flagged for the big mothership for landing. Each are 20 km long.

    I realized one thing today. This could made really simple with only SRBs. Just that it is then heavier and has no throttle and is not reusable.

    Afore mentioned set up could serve the Mothership on orbit...which could be made into a space lab ( LH2/LOX tank refurbished with B-29 type "wind screen " ).

    This is totally different bird here now.

    This is the minimum 2 seater to orbit Earth at LEO.

    Unlike Solar Impulse this uses full solar power and the battery capacity.

    More tweaking. No the cost to put men on the orbit is just 120 000 Euros per person. The plane + rocket will bring also satellites to orbit with les than a 3 million.

    T-Bird can take off like an aeroplane now...as it has more wing area and less mass.

    Turned to LH2/LOX fuel...it is lighter but bigger and thus the structure can be lite as well.

    Question

    Space Shuttle weighed 2 060 000 kg almost as much as Apollo did. I am proposing a craft that is fully reusable that weighs just 21 metric tons...around 100 x less. I has an effect on the fares too. I figure 260 000 euros per ticket to ISS ( fuel is just 8000 euros per person ).

    I am inclined to assume even James Bond ( 007 ) might like this ??

    My previous design with long wings did not look good in 3D so I switched to an alternate design.

    To make that design soar with less energy it was tweaked like this.

    Stars are closing us fast with DS¤G; https://en.wikipedia.org/wiki/Dual-Stage_4-Grid

    ISP is 21 500 s !!!!

    Using DS4G + the solar panels on my system and the new smaller rocket inside the Solar Eagle the delta -v can be even 206 -250 depending how much Xenon you can afford...heck even1000 km/s ( if as much volume as normal rocket fuel takes as liquid xenon is 16,4 x more dense).

    Yes yes yes ! We are to chasing the " impossible ". ( Proxima Centaur system )

    Here is the engine that it needs 18 pieces.

    Siemens 260 kW.

    This enables 35 km ( 110 000 ft ) drop altitude. Thus M2 before inginting the engines.
