The Earth Surface Mineral Dust Source Investigation (EMIT) mission instrument (right) sits in the "trunk" that will travel aboard SpaceX's 25th cargo resupply mission – planned for June 7, 2022 – to the International Space Station. This image was taken May 3, 2022, at SpaceX's Dragonland facility in Florida. Developed at NASA's Jet Propulsion Laboratory in Southern California and launching from Kennedy Space Center in Florida, EMIT will map the world's mineral-dust sources, gathering information about particle color and composition as it orbits over the planet's dry, sparsely vegetated regions. After being mounted on the space station, EMIT will collect measurements of 10 important surface minerals – hematite, goethite, illite, vermiculite, calcite, dolomite, montmorillonite, kaolinite, chlorite, and gypsum – in arid regions between 50-degree south and north latitudes in Africa, Asia, North and South America, and Australia. The data EMIT collects will help scientists better understand the role of airborne dust particles in heating and cooling Earth's atmosphere on global and regional scales. The white covering will prevent the spread of the heat the instrument generates, keeping it from affecting the space station and nearby instruments. EMIT will be one of two pieces of equipment transported to the space station in the external cargo "trunk" on SpaceX's Falcon 9 rocket. The other (left) is a Battery Charge/Discharge Unit. https://photojournal.jpl.nasa.gov/catalog/PIA25148

The cargo logistics module for Sierra Nevada Corporation’s Dream Chaser, the company’s reusable spaceplane, arrives at NASA’s Kennedy Space Center in Florida on Aug. 27, 2019. The cargo module – secured atop a truck – is being taken to Kennedy’s Space Station Processing Facility. A 15-foot attachment to Dream Chaser, the cargo module provides extra storage for payloads and provides cargo disposal upon re-entry into Earth’s atmosphere. Dream Chaser will deliver more than 12,000 pounds of cargo to the International Space Station under NASA’s Commercial Resupply Services 2 contract. The spacecraft and cargo module will begin resupply and return services missions to the space station in late 2021.

This spectacular photo is of the May 27, 1999 liftoff of the Orbiter Discovery (STS-96). The STS-96 mission, of almost 10 days, was the second International Space Station (ISS) assembly and resupply flight and the first flight to dock with the station. The crew installed foot restraints and the Russian built crane, STRELA. The Shuttle's SPACEHAB double module carried internal and resupply cargo for station outfitting and the Russian cargo crane was carried aboard the shuttle in the integrated Cargo Carrier (ICC).

The STS-96 mission, the second International Space Station (ISS) assembly and resupply flight, launched on May 27, 1999 aboard the Orbiter Discovery for an almost 10 day mission. The Shuttle's SPACEHAB double module carried internal and resupply cargo for station outfitting and the Russian cargo crane, STRELA, was carried aboard the shuttle in the integrated Cargo Carrier (ICC). In this STS-96 onboard photo of the first Extra Vehicular Activity (EVA), Mission Specialist Tamara Jernigan totes part of the Russian built crane. Jernigans' feet are anchored on a mobile foot restraint cornected to the Shuttle's Remote Manipulator System (RMS) operated by Mission Specialist Ellen Ochoa. The STS-96 flight was the first to perform docking with the ISS.

The remaining time-sensitive payloads bound for the International Space Station on SpaceX’s 21st Commercial Resupply Services (CRS-21) mission are loaded into the Cargo Dragon spacecraft on Friday, Dec. 4, 2020. A SpaceX Falcon 9 rocket, carrying the Cargo Dragon, lifted off from Launch Complex 39A at Kennedy Space Center in Florida at 11:17 a.m. EST on Dec. 6, 2020. The spacecraft is delivering more than 6,400 pounds of science investigations and cargo to the orbiting laboratory.

A Northrop Grumman Antares rocket carrying a Cygnus resupply spacecraft is seen horizontal on Pad-0A for the final cargo load, Saturday, Feb. 8, 2020, at NASA's Wallops Flight Facility in Virginia. Northrop Grumman’s 13th contracted cargo resupply mission with NASA to the International Space Station will more than 7,500 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew. The CRS-13 Cygnus spacecraft is named after the first African American astronaut, Major Robert Henry Lawrence Jr., and is scheduled to launch at 5:39pm EST Sunday, Feb. 9.
