Astro-G (also known as VSOP-2) is a planned radio telescope satellite under development by JAXA. It is expected to be launched into elliptic orbit around Earth (apogee height 25,000 km, perigee height 1,000 km). Astro-G was selected in February 2006 against the competition of a proposed new X-Ray astronomy mission (NeXT) and a proposed solar sail mission to Jupiter. Funding started from FY 2007 with a budget of 12 billion yen, around 100 million US dollars.
