Later this year, an ambitious new Earth-monitoring satellite will launch into a polar orbit around our planet. The new satellite—called JPSS-1—is a collaboration between NASA and NOAA. It is part of a mission called the Joint Polar Satellite System, or JPSS.

If you bought one of the original MicroMacxx® rockets, it came with its own launch pad, launch controller, and igniter holder. If your club has a set of standard launch pads, this pad and controller does not really work well with them. Also, newer MicroMaxx® rockets with clustered engines don’t work at all with the single igniter holders in the original pad.

Those of you, who know me, know I like rack rockets. A rack rocket is like a multi stage rocket, except that the stages do not separate. There is only one stage and the engines pop out the back as they burn, lighting the next engine in turn. It takes some special engineering to make these rockets work as the fire from the second stage and up is playing over the fins and the wooden rails that the fins are attached to and that align the stack of engines.
