SpaceDev (OTC BB:SPDV.OB) has been awarded three contracts to deliver over 200 satellite components for Mitsubishi Electric Corporation. The contracts, totaling approximately $800,000, will provide hardware in support of several commercial satellites and will expand the Company’s business in Japan. SpaceDev will provide its patented Starsys Cell Shorting Device (CSD), a battery cell bypass device incorporating its Starsys high output paraffin technology. The device monitors the health of individual battery cells and automatically isolates a cell from the spacecraft, preserving the integrity of the spacecraft power supply. Deliveries are scheduled to begin in November 2007.

“We are very pleased with our relationship with Mitsubishi and in the confidence they have shown in us with this order. We are highly positive about growing our commercial business in Japan. We believe that this type of contract will continue to expand our client diversity and grow our core and commercial satellite business,” said Mark N. Sirangelo, SpaceDev’s Chairman and CEO. “The CSD is a space flight proven product, with hundreds of units on orbit and over 11 million hours of successful in-service operation. As satellite power needs and duty cycles increase, the batteries provide crucial mission capabilities. High efficiency cell shorting devices prolong the battery life and improve the system reliability of these valuable assets.”
