Telescopes are typically mounted on satellites in space or grounded in earth-bound observatories. Dan Watson, however, is concerned in a NASA idea that puts telescopes in a opposite realm—the earth’s stratosphere.
Watson, highbrow and chair of physics and astronomy during Rochester, is partial of a group of researchers building new orchestration for the Stratospheric Observatory for Infrared Astronomy (SOFIA). Unlike standard observatories, SOFIA is situated on a Boeing 747SP jet airliner.
“SOFIA is NASA’s third-generation high-altitude airborne observatory,” Watson says. “The University of Rochester and airborne astronomy go approach back. [Rochester] professors Judy Pipher and Bill Forrest celebrated on both a initial and second era airborne telescopes, and we used a second era one for my PhD thesis.”
The jet that now houses SOFIA is mutated to lift a 2.5-meter hole telescope. It can fly during altitudes of 39-45,000 feet, somewhat aloft than a standard blurb airliner, and is customarily aloft for about 900 hours per year. At these altitudes, a instruments on house can see astronomical objects in infrared light that typically evade ground-based observatories: many infrared wavelengths are engrossed by H2O fog in a earth’s atmosphere before reaching a ground.
SOFIA also plays an critical purpose in building modernized space instruments. New technologies can be used on SOFIA sooner, and can be optimized some-more easily, than on space-based observatories.
As partial of a group led by Harvey Moseley, a comparison astrophysicist at NASA’s Goddard Space Flight Center in Maryland, Watson is assisting to rise HIRMES, a high-resolution, mid-infrared spectrometer that will be partial of SOFIA. HIRMES’s categorical idea is to magnitude a composition, location, and motions of gas and icy solids within disks orbiting really immature stars, about a million years old. At this age, a disks are actively giving birth to planets, out of these ingredients.
“HIRMES will exhibit pivotal sum of these protoplanetary disks—decisively critical for a planet-formation process—that haven’t formerly been probable to observe, even from space,” Watson says.
HIRMES is now set to start observational flights on SOFIA in 2019.
