  2. Reflecting telescope - Wikipedia

    en.wikipedia.org/wiki/Reflecting_telescope

    The Yolo was developed by Arthur S. Leonard in the mid-1960s. [22] Like the Schiefspiegler, it is an unobstructed, tilted reflector telescope. The original Yolo consists of a primary and secondary concave mirror, with the same curvature, and the same tilt to the main axis. Most Yolos use toroidal reflectors. The Yolo design eliminates coma, but ...

  3. Toroidal reflector - Wikipedia

    en.wikipedia.org/wiki/Toroidal_reflector

    Toroidal mirrors are used in Yolo telescopes and optical monochromators. In these devices, the source and detectors of the light are not located on the optical axis of the mirror, so the use of a true paraboloid of revolution would cause a distorted image.

  4. Cassegrain reflector - Wikipedia

    en.wikipedia.org/wiki/Cassegrain_reflector

    Light path in a Cassegrain reflecting telescope. The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture.

    The Corrective Optics Space Telescope Axial Replacement (COSTAR) is an optical correction instrument designed and built by NASA. It was created to correct the spherical aberration of the Hubble Space Telescope ' s primary mirror , which incorrectly focused light upon the Faint Object Camera (FOC), Faint Object Spectrograph (FOS), and Goddard ...

    Shortly after its establishment, the squadron undertook a number of operations, including the launch of a DSCS III and a NATO IV communications satellite, support for the Hubble Space Telescope repair mission, and the deployment of the Inertial Upper Stage (IUS) for NASA missions.

    A seven-hour EVA was also conducted to evaluate Hubble Space Telescope repair tools and methods. After the SPAS spacecraft had completed six days of free flight some 40 miles from Discovery, the crew completed a successful rendezvous and recovered the SPAS with the Shuttle's robot arm. The mission concluded with the first night landing of the ...

    Archinaut aimed to enable in-space production and assembly of the backbone structures for large telescopes, repair, augmentation, or repurposing of existing spacecraft, and robotic assembly of new space stations. MIS performed ground testing of a central spar onto which rolled up solar arrays can be extended and locked into place.
