Media Lario S.r.l. has completed the build of the 2.5 meter telescope for the ASTHROS mission of NASA’s Jet Propulsion Laboratory (JPL). The mission will use a balloon the size of a football stadium to send the telescope above the stratosphere over Antarctica to study star formation.
The optical system of the telescope is comprised of gold-coated panels which form the primary mirror, precisely aligned on a carbon fibre support structure which is lightweight yet strong enough to maintain the mirror’s precise shape during flight. The mirror has been produced using Media Lario’s patented Repli-formed Optics™ technology and is similar to the mirrors produced for the Atacama Large Millimeter Array (ALMA), located in the Atacama Desert of Chile.
