TOKYO -- In the growing business of private space, small, relatively cheap rockets are a particular area of interest. Japanese startup Interstellar Technologies has jumped in and is trying to close the gap with its U.S. competitors.
Although Interstellar, based on the northern island of Hokkaido, saw the first launch of its Momo rocket fail, it has no choice but to keep honing its technology and cutting prices. Competition in commercial space is relentless.
