for human space flight they use the Space shuttle.
The astronauts of Apollo 13 , had to use the lunar module to return to the earth after the spacecraft had exploded.
NASA uses computers in many different ways. NASA uses computers to calculate spacecraft trajectories, figuring out where to aim a spacecraft so it will reach a particular point or orbit in space at a particular time. NASA uses computers to track spacecraft after launch, calculating how to keep them on course with minimum fuel use. This involves a compromise between waiting as long as possible to make a correction (so the actual course is known better) and correcting as soon as possible (to use less fuel for a given correction). NASA uses computers on board the spacecraft themselves to control guidance systems, propulsion systems, experiments and everything else. NASA uses computers to analyze data sent back from space missions. NASA uses computers to keep track of the thousands of objects that orbit the earth today. NASA uses computers for every administrative purpose that any other large organization would use them for, such as budgeting, personnel, word processing, e-mail, its Web site, etc., etc. It might make more sense to ask "what does NASA not use computers for?" It would be a shorter list!
Solar cells are commonly used on spacecraft but because a spacecraft might spend a considerable amount of time in the dark they also have fuel power. They most obviously use oil based fuel to launch the spacecraft into space.
NASA avoids any use of religious texts or philosophies when planning and executing missions. However, that doesn't preclude astronauts from exercising their own religious freedoms when aboard spacecraft, as long as it doesn't interfere with the mission or their duties.
Formerly in use were the Challenger and Columbia Currently in use are the Endeavour, Atlantis, Discovery, and Enterprise

Lots of options. Once everyone stops being bitter about the cancellation of constellation (with good reason) NASA will be using Russian spacecraft for a short time, before hopefully using commercial spacecraft to reach the ISS. But for at least a decade NASA will be without its own spacecraft, entirely reliant on their old rivals or on the private sector, a far cry from the Apollo missions.

Yes. The NASA space shuttles use hypergolic chemicals to produce thrust vectoring to steer the orbiters in space.
The blueprints of the Saturn V rocket where lost in part, and the contractors closed, changed business, or aren't available to redo the same parts. The "Apollo" spacecraft will be replaced by the "Orion" spacecraft, and it wil use Ares as the rocket, instead of the Saturn from the 1960's.
The fuel of the Apollo spacecraft was a mixture of oxygen and nitrogen.
NASA and the US department of defense jointly commissioned the research and development of a technology solution to adress the challenges and requirements of communication with their spacecraft . Have been international standardized by the CCSDSISO which is consultative committee on space data systems and the international standards organization
Spacecraft make use of jet propulsion.
Einstein's. However, Newton's Law is still accurate in many situations and is usually easier to apply. For example NASA often use Newton's equations in calculations for spacecraft.
