The Cloud Aerosol Transport System (CATS) was a light detection and ranging remote sensing instrument designed to measure the location, composition and distribution of pollution, dust, smoke, aerosols and other particulates in the atmosphere. CATS was installed on the Kibo module of the International Space Station and was expected to run for at least six months, and up to three years. [1]

It was launched in January 2015 aboard the SpaceX CRS-5 resupply mission. CATS used a laser operating at three wavelengths (1064, 532, and 355 nm) to determine cloud layer height, thickness, and depth. Some of the applications of the data gathered will be to develop and refine climate models as well as providing insight for future examinations of the atmospheres of Mars, Jupiter, and other extraterrestrial atmospheres. [1] [2]

On October 31, 2017, CATS suffered a power failure and the main aperture door was left open. Because the door must remain closed when the instrument is on the light side of the Earth in the Sun on the pass after the failure the primary mirror was pointed towards the Sun and the optics were fried. On June 14, 2018 during a spacewalk Andrew J. Feustel succeeded in closing the aperture door and tied it shut with wire ties. CATS was disposed of on SpaceX CRS-17 when it was replaced by OCO-3. [3]

Venera 9, manufacturer's designation: 4V-1 No. 660, was a Soviet uncrewed space mission to Venus. It consisted of an orbiter and a lander. It was launched on June 8, 1975, at 02:38:00 UTC and had a mass of 4,936 kilograms (10,882 lb). The orbiter was the first spacecraft to orbit Venus, while the lander was the first to return images from the surface of another planet.

SCISAT-1 is a Canadian satellite designed to make observations of the Earth's atmosphere. Its main instruments are an optical Fourier transform infrared spectrometer, the ACE-FTS Instrument, and an ultraviolet spectrophotometer, MAESTRO. These devices record spectra of the Sun, as sunlight passes through the Earth's atmosphere, making analyses of the chemical elements of the atmosphere possible.

Cygnus is an expendable American cargo spacecraft developed by Orbital Sciences Corporation and now manufactured and launched by Northrop Grumman Space Systems as part of NASA's Commercial Resupply Services (CRS) program. It is usually launched by Northrop Grumman's Antares rocket, although three flights were on ULA's Atlas V and three are planned to launch on SpaceX's Falcon 9. It is designed to transport supplies to the International Space Station (ISS) following the retirement of the American Space Shuttle. Since August 2000, ISS resupply missions have been regularly flown by the Russian Progress spacecraft, as well as by the European Automated Transfer Vehicle, and the Japanese H-II Transfer Vehicle. With the Cygnus spacecraft and the SpaceX Dragon, NASA seeks to increase its partnerships with domestic commercial aviation and aeronautics industry.

Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS.

The Stratospheric Aerosol and Gas Experiment (SAGE) is a series of remote sensing satellite instruments used to study the chemical composition of Earth's atmosphere. Specifically, SAGE has been used to study the Earth's ozone layer and aerosols at the troposphere through the stratosphere. The SAGE instruments use solar occultation measurement technique to determine chemical concentrations in the atmosphere. Solar occultation measurement technique measures sunlight through the atmosphere and ratios that measurement with a sunlight measurement without atmospheric attenuation. This is achieved by observing sunrises and sunsets during a satellite orbit. Physically, the SAGE instruments measure ultraviolet/visible energy and this is converted via algorithms to determine chemical concentrations. SAGE data has been used to study the atmospheres aerosols, ozone, water vapor, and other trace gases.
