Where was the Hubble telescope tested before launch?
Perkin-Elmer, which built Hubble at its Danbury plant in Connecticut, tested the primary and secondary mirrors separately, but no one tested the complete telescope before launch. An earlier check by NASA absolved the design itself of blame, leading the agency to narrow the inquiry to possible errors in the testing of the mirrors.
Why did the Hubble mirror have the wrong shape?
By passing light between two mirrors and through a field lens, the instrument should have generated a wavefront matching the desired shape of the primary mirror. The mirror was finished to match the wavefront, so errors in the corrector meant that the final mirror had the wrong shape (see diagram).
Why was the refractive null corrector used on the Hubble telescope?
NASA says that it trusted the refractive null corrector because it had been ‘certified’ for final tests of the mirror’s shape. Perkin-Elmer, which built Hubble at its Danbury plant in Connecticut, tested the primary and secondary mirrors separately, but no one tested the complete telescope before launch.
What was the error that caused Hubble to not focus?
Preliminary analysis indicates that an error of this magnitude could cause the spherical aberration that prevents Hubble from focusing sharply. The crucial error, the misalignment of a lens by a millimetre, is ‘very large’ by optical standards, says Daniel Schroeder, an astronomer at Beloit College in Wisconsin, and a codesigner of Hubble.
