Summary

On 28 September, India plans to launch a major space-based observatory that will set a milestone for a developing country—and also mark a first for space science. The $45-million Astrosat mission will put India in an elite group of science powers—the United States, the European Union, and Japan—doing astronomy from orbit. The spacecraft also has a unique design. Instead of focusing on a single region of the spectrum, it carries a suite of five instruments, including two telescopes, which will observe cosmic objects simultaneously in several wavebands: visible, ultraviolet, and soft and hard x-rays. Astrosat's multiwavelength capability could pay special dividends with sources that flare up rapidly, such as x-ray binaries.
