Stay with Optimum Concept--Shuttle---Russia has with Soyus

As Aldrin says use and evolve Shuttle. We can use to repair and support on orbit assets and to place modules in orbit to explore other destinations. We should use what we have which is an optimum concept and it is PAID FOR. As we evolve we should consider the X37. This concept evolved to the x37 and ventureStar will meet America needs for decades.

It will enable us to explore the universe and work in earth orbit. Cancel SLS and JWT, save money and meets our needs. USA can operate shuttle commercially.

The Ultimate Solution--United Space Alliance runs Shuttle commercially--Cancel SLS/Orion & JWT
Judging from the comments being made, it appears that Americans lack the ingenuity,vision and education for the U.S. to progress in the future and lose our leadership in the world. Who's to blame? We are for believing that government will take care of us instead of standing up for ourselves. Critical thinking is becoming a lost cause because of people's dependency upon the Liberal media to provide information valuable for progress and instead to boost a certain president's popularity and re-electability. We all need to start thinking for ourselves and decide just where and what we need to do to become the great nation we once were. If we don't then look at the condition of Europe,that's where we're heading to.

The above comment is on a NASAWatch  article .  It is right on target regarding the overall direction of the USA, and the space program.
If one looks at mercury, Gemini, , Apollo and shuttle programs they were a reaction to a threat from another country.  We have never had a planned approach to space and probably never will.
People are all over the place in so far as what to do.  There are those who are anti shuttle concept, support various LV's. , anti and pro astronomy,  those that support missions to various destinations.

We need a strong leader who will get an overall plan in place.

Evolution of the shuttle makes the most sense since it is in existence and is paid for.  We don't have the money to develop SLS/mpcv, JWT and it is unlikely that commercial crew will be successful due to limited funds.  Shuttle will ensure Hubble and ISS are supported and continue to function and maintain the US capability.  THIS IS VERY IMPORTANT to National Security.

The above programs will likely be cancelled due to funding issues-- the USA is broke and the budget deficit is out of control.

For the USA to be preeminent in space, we must use and improve Shuttle.  Otherwise the USA is relegated to second or third place in space.
