A number of big-ticket science projects have been proposed in next year's budget, including:

The War on AIDS. Split between the Centers for Disease Control and the National Institute of Allergy and Infectious Diseases, the government will spend more than $1.3 billion, a 38 percent increase, on research and education. For basic research alone, the budget will rise from $467 million to $587 million next year.

The War on Cancer. This 15-year long battle continues to be well-funded, with the National Cancer Institute receiving a small increase, from $1.379 billion in 1988 to $1.468 billion in 1989, not counting funds it administers in the war on AIDS.

The Space Station. Four years ago, President Reagan endorsed in his state-of-the-union address, NASA's plan to build a space station. Since then, the project has been mired in technical and financial complications, but with the last budget of his presidency, Reagan has asked for nearly $1 billion to propel the project forward. More than $2 billion already has been allocated to replace the space shuttle Challenger.

The Pathfinder Project: Pathfinder is designed to develop a new set of technologies -- life-support systems, propulsion systems -- needed to put Americans back on the moon or propel them to Mars. Next year, the program will receive more than $100 million.

Super-Conducting Super-Collider. The Department of Energy wants to build a new atom smasher, usually called the SSC. Even though a site has yet to be selected, $363 million has been requested for fiscal year 1989 to start building what has been called the world's biggest scientific instrument, a proton-proton collider that will smash protons with energies of 40 trillion electron volts, 20 times more powerful than the most powerful colliders now in existence. Total cost is expected to reach $4.4 billion.

Clean Coal Technology Development. DOE has been funded to the tune of $1.775 billion to support the development of technologies that can burn coal cleanly, minimizing air pollution, in both new and old power plants.
