The Russians made it to space first, but ever since NASA has been the leader in the development of technology and exploration of near space and earth.
Space is a very dangerous environment. It is cheaper and more practical to send unmanned robotic spacecraft to do our research, but in the end we do not believe we've been there unless we go ourselves!
Look before you leap! Right now we can leap a small distance but we have to spend most of our effort just looking and theorizing! This section and the next is concerned with looking, from hobby to enormous projects.

Many big facilities - Hubble, XRay, Infra Red, Radio, Multiple mirrors and large arrays.
Can we do it cheaper and cleaner?
The new International Space Station (ISS) project is under way now involving NASA, ESA and the Russian Space Agency. Why are they doing it? Are the reasons scientific or political?

Which is the first part assembled in space?
Smaller, cheaper, further etc. If we put them in orbit around Terra we call them Satellites, but if we send them to other planets or further we call them spaceships or probes. Even Earth satellites have enough rocket power to take a trip or two round the moon and back as one had to recently because it was initially placed in a useless orbit - by accident.
SETI: the Search for Extra Terrestrial Intelligence.
By calculation people hypothesized planet X but later discoveries
have invalidated those calculations.
Other planets have been imagined and there were claims of a sighting
of Vulcan but it has not been seen since.
Lunatic Fringe and Paranoia? - imaginings about aliens - what are the chances of a spaceship reaching us from any other star system?
