Technical Session V: Getting There
Abstract
Sophisticated 3U or 6U Cubesats with modular design approach and plug-and-play technology could accommodate a wide range of missions. Small and medium-sized enterprises nowadays develop and sell standardized Cubesat kit to worldwide users. Some of them even become Cubesat one-stop-shop, providing coordination for launch opportunity in addition to kit distribution. Many space agencies use these companies to manage ride share of multiple users. Current nano/micro satellite users have to rely on piggyback ride and share ride on medium-heavy rocket where they have few choices on launch window and orbit selection. As capability of nano/micro satellites grows and mission utility increases, private ride or dedicated launch becomes more favorable space access tool. Authors conduct concept study on SpaceSpike rocket capable of lifting up to a 10kg or less to 40kg satellite to LEO. Targeting a commercial air launch system for a 150kg satellite to polar orbit, authors also develop key technologies under ALSET (Air Launch System Enabling Technology) R&D project funded by METI (Ministry of Economy,Trade and Industry). This paper introduces SpaceSpike rocket series, ALSET and the development of small launcher avionics, and new rocket concept “μLambda”. Trade study to make low-cost μLambda launch system and service a reality in short period is also conducted.
