53 <p><strong>OpenRocket</strong> is a Free, fully featured model
54 rocket simulator written in Java. It can be used to design and
55 simulate rockets before actually building and flying them.
57 <p>OpenRocket features a full six-degree-of-freedom simulation,
58 realistic wind modeling, a multitude of different components
59 including free-form fins and canted fins, clustering and
60 staging. Read more about its <a href="features.html">features</a>.
62 <p>Best of all, OpenRocket is Open Source—its source code is
63 freely available to study and extend. Anybody wishing to
64 contribute to the project can do so according to the
65 <a href="license.html">GNU GPL</a>. Simply
66 <a href="download.html">download</a> the source code
67 and start hacking, or <a href="download.html">get the ready
68 package</a> to begin designing and simulating.
70 <p>OpenRocket is still considered to be <strong>beta
71 software</strong>—there will still be bugs and occasional
72 problems. If you encounter problems, please
73 <a href="contact.html">report them</a> so they can be fixed.
