How do I install Java on my computer?

If you do not have a Java-capable browser, we recommend that you upgrade your current browser to either Netscape 3.01 or Internet Explorer 3.0. These browsers can be downloaded for free at the following URLs:

http://www.microsoft.com/windows/ie/download - To get Internet Explorer 3.0
http://home.netscape.com/download - To get Netscape 3.01

We do not endorse either of these products. We only recommend them because they are very stable and completely free.

[It is quite possible that you currently have a Java-capable browser, but your network administrators are not allowing Java to pass through the firewall. If this is the case, I'm afraid your only option is to convince your network administrators that they are severely hindering your ability to call upon the vast resources of the Internet, and that without having these resources readily available you feel that you are unable to reach your full potential.]


Why are there so many things that require Java support on your site? Is there somewhere I can download Java?

Our programmers chose Java because it provides us with the tools we need to make the more advanced games, while at the same time allowing the broadest audience to have access to these games.

You do not download Java. The required software to run Java applets is built into your Web browser. Netscape's version 3.0 and higher and Internet Explorer's 3.0 and higher support Java. To find out the version of your Web browser, go to the help pull-down menu and then select About. If you have either of these browsers with a version number greater than 3.0 you should be capable of using Java applets on Web sites.


What is an applet?

Java applets are little programs that actually run inside the confines of your Web browser. You do not need to install anything onto your machine other than a Web browser which supports Java (either Netscape's version 3.0 or higher or Internet Explorer 3.0 or higher). If you have one of these browsers, then you should not have any problems seeing or using Java applets.


Is the American flag still on the Moon?

Yes, the flag is still on the Moon. The first U.S. flag on the Moon was deployed by Neil Armstrong and Edwin "Buzz" Aldrin during their historic EVA (extravehicular activity) on 20 July 1969 (at 4 days, 14 hours and 9 minutes mission-elapsed time). The flag was seen worldwide on live television. At their technical crew debriefing, Armstrong and Aldrin reported a few problems with the deployment. They had trouble extending the horizontal telescoping rod and could not pull it all the way out. This gave the flag a bit of a "ripple effect," and later crews intentionally left the rod partially retracted. The Apollo 11 astronauts also noted that they could drive the lower portion of the pole only about 6 to 9 inches into the surface. It is uncertain if the flag remained standing or was blown over by the engine blast when the ascent module took off.

Can I buy a star and name it for someone, or have it named for me?

Some commercial firms may claim to officially register a name of your choice for a star. However, stars and other scientific discoveries are most often named by their discoverers. The names of stars are formally certified by the International Astronomical Union.
