Overall view of the news media at the memorial service at JSC for the Crew of STS 51-L.

This is the NASA News Center at Kennedy Space Center in Florida, where reporters from television, radio, print and online media outlets have monitored countless launches, landings and other space events in order to deliver the news to the world.

S86-26428 (31 Jan. 1986) --- Dozens of cameras and thousands of eyes focus on President Ronald Reagan (out of frame at left) during the 51-L memorial services Jan. 31 on the mall at the Johnson Space Center (JSC). The photograph was taken from special bleachers quickly erected to accommodate hundreds of members of the news media. The audience of thousands was largely made up of JSC employees and family and friends of the Challenger crew members who perished four days earlier in the attempted launch of NASA’s 25th STS mission.

Media and staff in the NASA News Center at Kennedy Space Center applaud the successful landing of Atlantis, visible on the television screens, at NASA's Dryden Flight Research Center at Edwards Air Force Base in California. Returning from mission STS-117, Atlantis touched down on runway 22 at Edwards on orbit 219 after 13 days, 20 hours and 12 minutes in space. The landing was diverted to California due to marginal weather at the Kennedy Space Center. Main gear touchdown was at 3:49:38 p.m. EDT on runway 22. Nose gear touchdown was at 3:49:49 p.m. and wheel stop was at 3:50:48 p.m. This was the 51st landing for the Space Shuttle Program at Edwards Air Force Base. The mission to the International Space Station was a success, installing the S3/S4 truss. The returning crew of seven includes astronaut Sunita Williams, who was flight engineer on the Expedition 15 crew. She achieved a new milestone, a record-setting flight at 194 days, 18 hours and 58 minutes, the longest single spaceflight ever by a female astronaut or cosmonaut.

VANDENBERG AIR FORCE BASE, Calif. – Ken Jucks, Orbiting Carbon Observatory-2 project executive at NASA Headquarters, participates in a mission science briefing at Vandenberg Air Force Base in California prior to the launch of the observatory, or OCO-2. Launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 is scheduled for 5:56 a.m. EDT on July 1. OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural "sinks" that absorb carbon dioxide and help control its buildup. The observatory will measure the global geographic distribution of these sources and sinks and study their changes over time. To learn more about OCO-2, visit http://www.nasa.gov/oco2.

S85-37164 (8-12 July 1985) --- Sharon C. (Christa) McAuliffe of Concord High, Concord, New Hampshire, talks to the media at Johnson Space Center. Christa McAuliffe was eventually chosen as the first Teacher in Space and was a member of the seven-member Challenger shuttle crew which died tragically in the explosion of the spacecraft during the launch of STS-51L from the Kennedy Space Center about 11:40 a.m., EST, on Jan. 28, 1986. The explosion occurred 73 seconds into the flight as a result of a leak in one of two Solid Rocket Boosters that ignited the main liquid fuel tank. The crew members of the Challenger represented a cross-section of the American population in terms of race, gender, geography, background, and religion. The explosion became one of the most significant events of the 1980s, as billions around the world saw the accident on television and empathized with any one of the several crew members killed.

The KSC Press Site is seen from the air. The large white building is the NASA News Center. At lower left are the grandstands that provide viewing of Shuttle launches for the media. Stretching from the News Center to the right are buildings and trailers occupied by television media and other news agencies such as Associated Press and Reuters.

The NASA News Center, seen here, is the hub of news operations for the media, providing information and contacts about Space Shuttle processing and other activities around KSC. News Center staff also conduct media tours, escorting journalists and photo/videographers to key sites such as the launch pads and Vehicle Assembly Building as needed.

Jennifer Boland-Masterson, director of Boeing Operations at NASA’s Michoud Assembly Facility in New Orleans, talks with media prior to the Green Run hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket at Stennis Space Center near Bay St. Louis, Mississippi, on Jan. 16, 2021. NASA conducted a hot fire test of the core stage’s four RS-25 engines on the B-2 Test Stand at Stennis. Scheduled for as long as eight minutes, the engines fired for a little more than one minute to generate a combined 1.6 million pounds of thrust, just as will occur during an actual launch. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the SLS core stage prior to launching the Artemis I mission to the Moon.
