We can start a mars colony by delivering 50-100 men and women there to live permanently of mars. The couples can marry procreate and have large familys with...
I have created a table showing some methods of propelling crewed spacecraft to mars. Also some rocket designs that could be used to get us to mars can be found...
Mars should be colonized by private persons using private financing in the following way. Private persons need to buy their own medium lift or heavy lift space...
1. Use the third or 4th stage of a chemical powered heavy lift rocket as a small interplanetary spacecraft. 2. The mass will be in the range 20,000 to 100,000 ...
How is this more practical then Zubrin's Mars Direct plan? In which chemical rockets take the return vehicle directly to the surface of Mars, refueling with...
A round trip manned mars mission needs a characteristic mission cumulative delta v of 12-15 kilometers a second starting just from earth orbit let alone from...

That is the point of Zubrins Mars Direct. It would be sent without the fuel for the return flight. You would bring with you 5.8 tons of Hydrogen, which with...
the system i proposed is a varient of mars direct. The difference is it uses advanced propulsion in the terminal stage that allows round trip between earth...
Your proposal adds the R and D of a new untested propulsion system raising the price and time of a Mars mission unnecessarially. It calls for sending supplies...
The advanced propulsion systems used in the terminal stage of my crewed mars space craft design are neither new nor untested. The first nuclear thermal rocket...
A. solar light sail propelled spacecraft can travel between earth orbit and mars orbit with out using any propellant at all.It can do this a potentially...
None of these rocket engines have been used on manned flights or on ships as large as will be required for a Mars mission. So they are still not off shelf....
The engines are proven already on unmanned spacecraft and ground based tests. Using them on a manned flight merely requires scaling them up . Chemical powered...

A quibble with Tim's plan, at least for the future; whenever we can get political clout to use nuclear thermal upper stages, don't forget to include nuclear...
