Which of these programs has already launched, Astron or James Webb Space Telescope?
Astron
Title: Optical Telescope Element
Passage: Optical Telescope Element (OTE) is a sub-section of the James Webb Space Telescope, a large infrared space telescope scheduled to be launched in October 2018.  The OTE consists of some major parts of the telescopes including the main mirror, the secondary mirrors, the framework and controls to support those mirrors, and various thermal and other systems to support the functioning of the telescope.  The other two major sections of the JWST are the Integrated Science Instrument Module (holds instruments) and the Spacecraft Element (SE), which includes the Spacecraft Bus and Sunshield.  The OTE collects the light and sends it to the science instruments in the ISIM.  The OTE has been compared to being the "eye" of the telescope and the backplane of it to being the "spine".
Title: James Webb Space Telescope
Passage: The James Webb Space Telescope (JWST) is a space telescope that is part of NASA's Next Generation Space Telescope program, developed in coordination between NASA, the European Space Agency, and the Canadian Space Agency.  It is scheduled to launch in 2019 and will be located near the Earth–Sun L lagrangian point.  The telescope will offer unprecedented resolution and sensitivity from the long-wavelength (orange to red) visible light through the mid-infrared (0.6 to 27 micrometer) range.
Title: Astron (spacecraft)
Passage: Astron was a Soviet spacecraft launched on 23 March 1983 at 12:45:06 UTC, using Proton launcher, which was designed to fulfill an astrophysics mission.  It was based on the 4MV spacecraft design and was operational for six years as the largest ultraviolet space telescope during its lifetime.  The project was headed by Alexandr Boyarchuk.
