Spektr-R
High Quality Content by WIKIPEDIA articles! Spektr-R (or Radioastron) is a Russian orbital radio telescope, and currently the largest space telescope in orbit. It is funded by the Russian Astro Space Center, and was launched into Earth orbit on 18 July 2011, with a perigee of 10,000 kilometers (6,200 mi) and an apogee of 390,000 kilometers (240,000 mi), about 700 times of the orbital height of the Hubble Space Telescope. The main scientific goal of the mission is the study of astronomical objects with an angular resolution up to a few millionths of an arcsecond. This is accomplished by using the satellite in conjunction with ground-based observatories and interferometry techniques.
