S71-56478 (December 1971) --- Astronaut James B. Irwin

The fifth marned lunar landing mission, Apollo 15 (SA-510), carrying a crew of three astronauts: Mission commander David R. Scott, Lunar Module pilot James B. Irwin, and Command Module pilot Alfred M. Worden Jr., lifted off on July 26, 1971. Astronauts Scott and Irwin were the first to use a wheeled surface vehicle, the Lunar Roving Vehicle, or the Rover, which was designed and developed by the Marshall Space Flight Center, and built by the Boeing Company. Astronauts spent 13 days, nearly 67 hours, on the Moon's surface to inspect a wide variety of its geological features.

This is an X-SAR image spanning an area of approximately 20 kilometers by 40 kilometers (12 miles by 25 miles) of the island of Hong Kong, the Kowloon Peninsula and the new territories in southern China, taken by the imaging radar on board the space shuttle Endeavour on October 4, 1994. North is toward the top left corner of the image. The Kaitak Airport runway on Kowloon Peninsula (center right of image) was built on reclaimed land and extends almost 3 kilometers (nearly 2 miles) into Victoria Harbor. To the south of the harbor lies the island of Hong Kong. The bright areas around the harbor are the major residential and business districts. Housing more than six million residents, Hong Kong is the most densely populated area in the world. The large number of objects visible in the harbor and surrounding waters are a variety of sea-going vessels, anchored in one of the busiest seaports in the Far East. http://photojournal.jpl.nasa.gov/catalog/PIA01750

jsc2011e118361 - Panorama view of Apollo 15 lunar module pilot James B. Irwin, using a scoop in making a trench in the lunar soil during the second moonwalk of the mission. The panoramas were built by combining Apollo 15 images starting with frame AS15-92-12420 thru end frame AS15-92-12438. The panoramic images received minimal retouching by NASA imagery specialists, including the removal of lens flares that were problematic in stitching together the individual frames and blacking out the sky to the lunar horizon. These adjustments were made based on observations of the Moon walkers who reported that there are no stars visible in the sky due to the bright lunar surface reflection of the Sun.

Chemist Tesia Irwin tests a 3D printer on July 28, 2022, at Swamp Works at NASA’s Kennedy Space Center in Florida, as part of the Relevant Environment Additive Construction Technology (REACT) project. Among the key objectives of the project is developing an architectural and structural design for a shelter that provides protection to habitable assets on the lunar surface. Testing REACT derives from NASA’s 2020 Announcement of Collaboration Opportunity with AI SpaceFactory – an architectural and construction technology company and winner of NASA’s 3D Printed Habitat Challenge.
