Game Changing Japanese Mini-rocket Fails First Launch; Promise of Cheaper Flights Remains

Japan's first attempt to launch the world's smallest launch vehicle failed, but the promise of spaceflights for small satellites costing up to 90% cheaper than today's mammoth launch costs remains.

The weapon Japan is using in an attempt to change the face of the commercial launch industry is a rocket named SS-520 F4. The rocket was developed by JAXA (Japan Aerospace Exploration Agency) to meet the growing global demand for inexpensive launch vehicles designed to orbit small satellites such as cube satellites or CubeSats.

The cost of building the rocket, including the launch cost, came to a mere $4.35 million, according to JAXA. In contrast, it costs $61million alone to launch a SpaceX Falcon 9 without the re-usable first stage. With the re-usable first stage, the cost of a Falcon 9 launch should plummet to $43 million.

Falcon 9 is the cheapest launch vehicle on the world commercial launch market. Falcon 9, however, is a far larger vehicle at 70 meters tall and can carry far heavier payloads than the SS-520 F4.

The SS-520 F4, which stands only 10.7 meters (35 feet) tall, is a "mini rocket" described as the world's smallest satellite launch vehicle. JAXA described vehicle as a very small three-stage rocket developed from the SS-520, a two-stage sounding rocket.

The very smallness of the SS-520 F4, however, confers on it the potential to reduce the cost of sending small satellites into low Earth orbit by as much as 90%. The rocket was launched from the Uchinoura Space Center in southern Japan at 8.30 a.m. on Jan. 15.

"The first stage of the rocket's flight went as planned. However, we were unable to receive (data) from the unit as it continued the flight," said JAXA.

The rocket then stopped sending data back to mission control soon after it left the ground. As a result, JAXA decided to abort the mission, causing the rocket to crash into the sea with its payload.

Lost with the rocket was its sole payload, the TRICOM-1 nano-satellite weighing only three kilograms developed by the University of Tokyo and designed to take high-quality images of the Earth. The satellite was to have been taken into low Earth orbit if the flight had been successful.

JAXA said it needs to first investigate the cause of the failure, but wants to maintain the existing policy of using commercial off-the-shelf equipment to build the rocket.

SS-520 F4 was designed with help from Canon Electronics and used parts from consumer electronics devices such as circuit boards and mobile phones.
