Airship Frequency's.
This this isn't Star Trek. This can't be used to beam yourself into space or across the country, and faster-than-light communication is still impossible. But that doesn't make this technology useless. Someday, quantum teleportation could be used as a form of encryption because if anyone intercepts the communication it'll mess up the entanglement and to send results from quantum computers around the world. On April 17, 2012, two upgrades to HAWC were selected by NASA to increase the field of view with new transition edge sensor bolometer detector arrays and to add the capability of measuring the polarization of dust emission from celestial sources.
The open cavity housing the telescope will be exposed to high-speed turbulent winds. In addition, the vibrations and motions of the aircraft introduce observing difficulties. The telescope was designed to be very lightweight, with a honeycomb shape milled into the back of the mirror and polymer composite material used for the telescope assembly. The mount includes a system of bearings in pressurized oil to isolate the instrument from vibration. Tracking is achieved through a system of gyroscopes, high speed cameras, and magnetic torque motors to compensate for motion, including vibrations from airflow and the aircraft engines.[10] The telescope cabin must be cooled prior to aircraft takeoff to ensure the telescope matches the external temperature to prevent thermally induced shape changes. Prior to landing the compartment is flooded with nitrogen gas to prevent condensation of moisture on the chilled optics and instruments.
DLR is responsible for the entire telescope assembly and design along with two of the nine scientific instruments used with the telescope, NASA is responsible for the aircraft. The manufacturing of the telescope was subcontracted to European industry. The telescope is German-made; the primary mirror was cast by Schott AG in Mainz, Germany with lightweight improvements, with grinding and polishing completed by the French company SAGEM-REOSC. The secondary silicon carbide based mirror mechanism was manufactured by the Swiss Center for Electronics and Microtechnology (CSEM). A reflective surface was applied to the mirror at a facility in Louisiana but the consortium now maintains a mirror coating facility in Moffett Field, allowing for fast recoating of the primary mirror, a process that is expected to be required 1-2 times per year.
