SPEKTR-R is long-delayed radio telescope designed to help astronomers see deeper into supermassive black holes, obtain views of collapsed stars and better measure the influence of dark energy on the cosmos. The craft's flight path will naturally shift due to the influence of the moon's gravity over the course of the five-year mission. It will take Spektr-R up to nine days to go around the Earth in its egg-shaped orbit. Spektr-R will next extend two solar arrays and unfurl its flower-like dish receiver antenna to a diameter of 10 meters, or almost 33 feet. It is comprised of 27 carbon fiber petals that take up to two hours to fully deploy. The Spektr-R satellite is one element of an international network of observatories in a project called RadioAstron. When linked with ground-based telescopes across the globe, Spektr-R will facilitate unprecedented views into black holes that form the centers of galaxies.
