Lectures by Dr. Bruce Betts of the Planetary Society, part 1 of 23

I'll put up one per week

Finally they decided to make an Orbiter installation system (a bit like mine  has been for the past two years).

You click on the Web installer and install what you want.

So now you should be OK right ? Well, not exactly.

• When you start Orbiter you have to go to the modules tab and activate everything.
• You won't have any sound until you go to Dansteph's page and download his sound module and while you're at it, might as well download his Delta Glider IV, the best ship to use with Orbiter.
• There is no icon for the Orbiter documentation, you need to browse to your install folder and look up the "doc" folder. Orbiter.pdf being the most important.

Then you can go to www.orbithangar.com and download whatever addons you want. Some are more popular than others, be careful about the published date, anything prior to the 2006 Orbiter release is not always compatible.

One addon I made compatible for you is TTM24 ( To the moon in 24 hours) Righ click on the link to download.

It it always a good idea to make a backup of your Orbiter folder if you intend to go a little crazy and try out all the fun ships you can download.

 My Orbiter package is still available in the download section, at least now you have to options.

 An important skill you must develop is to properly measure the volume of liquids using a graduated cylinder.

Use this test to become an expert (almost )

I have some neat images for you to download, print and use in your schools to decorate or print out as gifts.
