This week, Aerojet Rocketdyne, a GenCorp company, announced that it has successfully completed a series of hot-fire tests on a Bantam demonstration engine built entirely with 3D printing. This particular liquid oxygen/kerosene engine, dubbed "Baby Bantam" (because it is at the lower end of the Bantam engine family thrust range), has a thrust of 5,000 pounds.

Two trends are setting up nanosats for further success. Like people working on everything from robots to 3D printers, nanosat builders are harvesting the benefits of ever better, ever cheaper components built for smartphones and other consumer electronics. Some nanosats even contain complete smartphones, making use of the clever operating systems, radios and cameras which phones now contain. For as long as phones go on getting cheaper and more capable, so will nanosats. The cheapest so far—a tiny chipsat—was assembled for just $25, though it has yet to be successfully launched.
