SOFIA was based on a Boeing 747SP, a factory shortened version of the wide-body aircraft that had been modified to include a large door in the aft fuselage that could be opened in flight to allow a 2.5 m (8.2 ft) diameter reflecting telescope access to the sky. [2] .

2024年2月6日 · SOFIA, the Stratospheric Observatory for Infrared Astronomy, was a Boeing 747SP aircraft modified to carry a 2.7-meter (106-inch) reflecting telescope (with an effective diameter of 2.5 meters or 100 inches).

2022年9月30日 · Between Wednesday night and Thursday morning, NASA operated the last flight of the Boeing 747-SP carrying a reflecting telescope for the Stratospheric Observatory for Infrared Astronomy (SOFIA). This flight marked the end of an era, and now there’s the question of what will happen with this iconic aircraft.

“索菲亚”望远镜是一台口径大约2.5米的红外 反射式望远镜 ，搭载在一架经过改装的 波音747客机 内部，在飞机一侧开了一个门，让这台重达17吨的大型望远镜能够在绝大部分大气的上方观察夜空，在这样的高度上，绝大部分（超过99%）的大气和水汽产生的干扰 ...

2022年12月13日 · SOFIA is a modified Boeing 747SP jet that was operated out of Armstrong. The SOFIA mission’s operations ended on Sept. 29, 2022 , but the team of incredible and diligent pilots and mechanics continued to support SOFIA as it prepared to go to its new home. SOFIA is part of NASA’s legacy of airborne astronomy.

2023年1月30日 · The Stratospheric Observatory For Infrared Astronomy (SOFIA) was a telescope mounted on a Boeing 747 SP aircraft that studied infrared light, essentially...

2020年1月27日 · Here’s what you need to know about the Stratospheric Observatory for Infrared Astronomy, also known as SOFIA. From its outside appearance, the NASA Boeing 747 looks very much like any other. For the avgeeks, it’s already exciting, as it’s the rare and unusual SP version, a shorter model often used for VIP services.

2022年5月9日 · After operating for only eight years of its planned 20-year lifetime, the unique Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft, a retrofitted 747 with a 17-tonne reflecting...

2023年1月15日 · Last week, the National Aeronautics and Space Administration (NASA)'s unique Boeing 747 made its final journey to its permanent home at the Pima Air & Space Museum in Tucson, Arizona. The now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA) aircraft flew its final flight from NASA's Armstrong Flight Research Center in Palmdale ...

2022年12月20日 · SOFIA carried a reflecting telescope that observed the cosmos in infrared light. It flew into Earth's stratosphere, up to about 45,000 feet (13,700 meters), and collected data during 10-hour overnight flights, observing the Moon, planets, stars, nearby galaxies and more. SOFIA was a joint project of NASA and the German Space Agency at DLR.
