The National Aeronautics and Space Administration (NASA) Lewis Research Center’s Convair F-106B Delta Dart equipped with air sampling equipment in the mid-1970s. NASA Lewis created and managed the Global Air Sampling Program (GASP) in 1972 in partnership with several airline companies. NASA researchers used the airliners’ Boeing 747 aircraft to gather air samples to determine the amount of pollution present in the stratosphere. Private companies developed the air sampling equipment for the GASP program, and Lewis created a particle collector. The collector was flight tested on NASA Lewis’ F-106B in the summer of 1973. The sampling equipment was automatically operated once the proper altitude was achieved. The sampling instruments collected dust particles in the air so their chemical composition could be analyzed. The equipment analyzed one second’s worth of data at a time. The researchers also monitored carbon monoxide, monozide, ozone, and water vapor. The 747 flights began in December 1974 and soon included four airlines flying routes all over the globe. The F-106B augmented the airline data with sampling of its own, seen here. It gathered samples throughout this period from locations such as New Mexico, Texas, Michigan, and Ohio. In July 1977 the F-106B flew eight GASP flights in nine days over Alaska to supplement the earlier data gathered by the airlines.

In the early morning, the Stardust spacecraft, with the third stage of a Boeing Delta II rocket attached, arrives atop a transporter at Launch Pad 17-A, Cape Canaveral Air Station. The second and third stages of the rocket will be mated and prepared for liftoff on Feb. 6. Stardust is destined for a close encounter with the comet Wild 2 in January 2004.

This artist's concept shows Mars Sample Return Earth Entry System. The vehicle would bring curated Martian samples collected by NASA's Perseverance Rover on the final leg of their journey from Mars to Earth. The illustration shows the Earth Entry System, a capsule about 4 feet (1.25 meters) in diameter, on its final approach to Earth, after being ejected from the Earth Return Orbiter. Once in Earth's atmosphere, it would take the vehicle about six minutes to land at the U.S. Air Force's Utah Test and Training Range in west-central Utah. Velocity at time of touchdown for the parachute-less capsule is expected to be about 90 mph (40 meters per second). The Earth Entry System is part of the multi-mission Mars Sample Return program being planned by NASA and ESA (European Space Agency). https://photojournal.jpl.nasa.gov/catalog/PIA25986

Inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida, the Sample Caching System Sterile Flight Model hardware is being prepared for installation on the Mars Perseverance rover on May 21, 2020. The system includes 39 sample tubes that will be inserted into the underside of the rover. Each tube is sheathed in a gold-colored cylindrical enclosure to protect it from contamination. Perseverance rover will carry 43 sample tubes in total to Mars' Jezero Crater. The Mars Perseverance rover is scheduled to launch in mid-July atop a United Launch Alliance Atlas V 541 rocket from Pad 41 at nearby Cape Canaveral Air Force Station. The rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rover will search for habitable conditions in the ancient past and signs of past microbial life on Mars. The Launch Services Program at Kennedy is responsible for launch management.

This artist's concept depicts NASA's Mars 2020 rover on the surface of Mars. The mission takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself.
