Dear Amy: I love playing basketball, but I don't know all the rules. Can you help me? -- Asif, Gombak, Malaysia

Dear Asif: I love basketball too, but knowing all the rules of the game makes it much easier to understand. At www.learn2.com/05/0543/0543.asp you can learn step-by- step about the game. From its inventor, James Naismith, to what moves are considered fouls, this site will give you a great base of knowledge. If you want to learn more, www.fiba.com has a complete set of basketball rules that you can download. There are a lot of rules, so I hope you like reading. (The first site is no longer available.)

Dear Amy: Why can't astronauts go to Mars? -- Chrissy, Washington, D.C.

Dear Chrissy: A trip to Mars sounds intriguing, but making the more than 35 million-mile flight is a stretch for today's technology and astronauts. There's a fun rendition of what a trip to our neighbor planet would entail at www.discovery.com/area/science/mars/ mars.620.html. Perhaps the biggest challenge would be if astronauts did go to Mars, they might fly off the planet because Mars' gravity is only one-third of Earth's. (This site is no longer available.)
