The U.S. Army is developing a way to launch nanosatellites into orbit using nanomissiles. The nanosatellites use miniaturized technology that gives them most of the capabilities of their full-sized counterparts.
The Multipurpose Nanomissile System (MNMS), is being developed by the Huntsville, Alabama-based U.S. Army Space & Missile Defense Command (USASMDC).
The low-cost system has a multi-booster configuration which allows it to be tailored to different missions, according to a report from the USASMDC and the Army Forces Strategic Command (ARSTRAT). They can also be programmed for launch within 24 hours.
The nanosatellites cost between $300,000 and $1 million each, John London, SMDC's manager for nanosatellite technology programs told space.com.
"One of the reasons we like satellites of this class is we can afford to put a lot of them up there to where the entire constellation is still relatively inexpensive,” London said. “If one satellite up there fails, and I need to replace it with a $300,000 satellite in a very specific orbit, and the lowest cost launch vehicle out there is at least 30 to 50 times the cost of that spacecraft, that won't work."
According to the USASMDC report, the MNMS is able to keep costs low through a simple design. It has a tank-booster-engine design, uses a bi-propellant liquid engine, and uses current launch hardware.
“The configurable boosters can be tailored to many specific missions: missile defense target vehicle, infrared and radar sensor exerciser, hyper-sonic test vehicle for aerospace components, pop-up reconnaissance system, highly responsive orbital launch vehicle for very small payloads (10 kg to LEO) and even very long range strike with small conventional munitions,” according to the report.
The MNMS needed a dedicated missile that could boost it into orbit. When the project began, all of the military's missiles and rockets were designed as weapons.
The developers contracted Colsa Corp. and Dynetics Corp. in 2008 to develop the core booster, according to space.com. The project has cost $7 million to date, and needs an estimated $17 million more to be completed.
