The Lowell Observatory's High-speed Imaging Photometer for Occultation rests on its dolly in the lab prior to installation on the SOFIA airborne observatory.

The Apollo Telescope Mount (ATM), designed and developed by the Marshall Space Flight Center, served as the primary scientific instrument unit aboard the Skylab. The ATM contained eight complex astronomical instruments designed to observe the Sun over a wide spectrum from visible light to x-rays. This photo depicts a mockup of the ATM contamination monitor camera and photometer.

The Fly’s Eye Geostationary Lightning Mapper Simulator will map lightning strikes using 30 photometers, instruments that measure the intensity of light.

This drawing illustrates the Hubble Space Telescope's (HST's) High Speed Photometer (HSP). The HSP measures the intensity of starlight (brightness), which will help determine astronomical distances. Its principal use will be to measure extremely-rapid variations or pulses in light from celestial objects, such as pulsating stars. The HSP produces brightness readings. Light passes into one of four special signal-multiplying tubes that record the data. The HSP can measure energy fluctuations from objects that pulsate as rapidly as once every 10 microseconds. From HSP data, astronomers expect to learn much about such mysterious objects as pulsars, black holes, and quasars. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The HST views galaxies, stars, planets, comets, possibly other solar systems, and even unusual phenomena such as quasars, with 10 times the clarity of ground-based telescopes. The HST was deployed from the Space Shuttle Discovery (STS-31 mission) into Earth orbit in April 1990. The Marshall Space Flight Center had responsibility for design, development, and construction of the HST. The Perkin-Elmer Corporation, in Danbury, Cornecticut, developed the optical system and guidance sensors.

PUNCH, along with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), a space telescope, will launch aboard a SpaceX Falcon 9 rocket from Launch Complex 4E at Vandenberg Space Force Base in Central California on Thursday, Feb. 27, 2025.

A transport truck carrying NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), a space telescope, arrives at Vandenberg Space Force Base in California on Tuesday, Jan. 14, 2025. SPHEREx will enter a polar orbit around Earth and create a 3D map of the entire sky, gathering information about millions of galaxies for scientists to study what happened after the big bang, the history of galaxy evolution, and the origins of water in planetary systems in our galaxy. SPHEREx will launch aboard a SpaceX Falcon 9 rocket in late February 2025.
