Former Gemini and Apollo astronaut Tom Stafford speaks during the opening of the tribute exhibition to the Apollo 1 astronauts who perished in a fire at the launch pad on Jan. 27, 1967, during training for the mission. The tribute highlights the lives and careers of astronauts Gus Grissom, Ed White II and Roger Chaffee who were lost during the fire. The tribute at the Apollo/Saturn V Center at NASA's Kennedy Space Center opened Jan. 27, 2017, 50 years after the crew of three was lost. It features numerous items recalling the lives of the three astronauts. The tribute also includes the three-part hatch to the spacecraft itself, the first time any part of the Apollo 1 spacecraft has been displayed publicly. A version of the hatch after it was redesigned is also showcased as an example of improvements NASA made throughout the agency and to the Apollo spacecraft that would later carry astronauts to the moon.

Former Gemini and Apollo astronaut Tom Stafford speaks during the opening of the tribute exhibition to the Apollo 1 astronauts who perished in a fire at the launch pad on Jan. 27, 1967, during training for the mission. The tribute highlights the lives and careers of astronauts Gus Grissom, Ed White II and Roger Chaffee who were lost during the fire. The tribute at the Apollo/Saturn V Center at NASA's Kennedy Space Center opened Jan. 27, 2017, 50 years after the crew of three was lost. It features numerous items recalling the lives of the three astronauts. The tribute also includes the three-part hatch to the spacecraft itself, the first time any part of the Apollo 1 spacecraft has been displayed publicly. A version of the hatch after it was redesigned is also showcased as an example of improvements NASA made throughout the agency and to the Apollo spacecraft that would later carry astronauts to the moon.

CAPE CANAVERAL, Fla. – In the White Room on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-119 Mission Specialist Koichi Wakata is helped by the Closeout Crew to put on his harness. Wakata will join other crew members to enter space shuttle Discovery to conduct a simulated launch countdown. The astronauts are at Kennedy to prepare for launch through Terminal Countdown Demonstration Test activities. The TCDT includes equipment familiarization and emergency egress training. Discovery is targeted to launch on the STS-119 mission Feb. 12. During the 14-day mission, the crew will install the S6 truss segment and solar arrays to the starboard side of the International Space Station, completing the station's truss, or backbone.

CAPE CANAVERAL, Fla. – – In the White Room on the orbiter access arm of the fixed service structure on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-127 Mission Specialist Tom Marshburn finishes suiting up before entering space shuttle Endeavour for the simulated launch countdown. The crew is at Kennedy for a launch dress rehearsal called the terminal countdown demonstration test, or TCDT, which includes the simulation, emergency exit training and equipment familiarization. Endeavour's STS-127 mission is the final of three flights dedicated to the assembly of the Japanese Kibo laboratory complex on the International Space Station.

CAPE CANAVERAL, Fla. – – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the Closeout Crew in the White Room help STS-127 crew members complete their suitup before entering space shuttle Endeavour for the 6:03 p.m. EDT liftoff. Seen here are Mission Specialist Tom Marshburn (left) and Pilot Doug Hurley. Today will be the sixth launch attempt for the STS-127 mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues. Endeavour will deliver the Japanese Experiment Module's Exposed Facility and the Experiment Logistics Module-Exposed Section in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station.

This composite image shows a hot spot in Jupiter's atmosphere. In the image on the left, taken on Nov. 8, 2020, by NASA's Infrared Telescope Facility (IRTF) on the island of Hawaii, the hot spot appears bright in the infrared. The inset image on the right, taken by the JunoCam visible-light imager (also on Nov. 8, during Juno's 30th perijove pass), the hot spot appears dark and is flanked by high light-colored clouds to the south and a bright white storm to the west. Jupiter's hot spots have been known for a long time. On Dec. 7, 1995, the Galileo probe likely descended into a similar hot spot. To the naked eye, Jupiter's hot spots appear as dark, cloud-free spots in Jupiter's equatorial belt, but at infrared wavelengths, they are extremely bright, revealing the warm, deep atmosphere below the clouds. High-resolution images of hot spots such as these are key to understanding the role of storms and waves in Jupiter's atmosphere and to solving the mystery of Jupiter's elusive water. Citizen scientist Kevin Gill processed the image to enhance the color and contrast, with further processing by Tom Momary to map the JunoCam image to the IRTF data. The NASA IRTF is a 10.5-foot-diameter (3.2-meter-diameter) telescope optimized for infrared observations and is managed for NASA by the Institute for Astronomy at the University of Hawai'i. https://photojournal.jpl.nasa.gov/catalog/PIA24300

CAPE CANAVERAL, Fla. – On Launch Pad 39A at NASA's Kennedy Space Center in Florida, the closeout crew in the White Room help STS-127 crew members complete their suitup before entering space shuttle Endeavour for the 7:13 p.m. EDT liftoff. Seen here are Mission Specialist Tom Marshburn (left) and Pilot Doug Hurley. This is the fourth launch attempt for the STS-127 mission. The first two launch attempts on June 13 and June 17 were scrubbed when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. Mission managers also decided to delay tanking on July 11 for a launch attempt later in the day to allow engineers and safety personnel time to analyze data captured during lightning strikes near the pad on July 10. Endeavour will deliver the Japanese Experiment Module's Exposed Facility, or JEM-EF, and the Experiment Logistics Module-Exposed Section, or ELM-ES, in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station. STS-127 is the 29th flight for the assembly of the space. Photo credit: NASA/Sandra Joseph & Kevin O'Connell

CAPE CANAVERAL, Fla. - Launch of space shuttle Atlantis from Pad 39A at NASA's Kennedy Space Center in Florida surprises a great white egret passing near the pad. Liftoff on its STS-129 mission came at 2:28 p.m. EST Nov. 16. Aboard are crew members Commander Charles O. Hobaugh; Pilot Barry E. Wilmore; and Mission Specialists Leland Melvin, Randy Bresnik, Mike Foreman and Robert L. Satcher Jr. On STS-129, the crew will deliver two ExPRESS Logistics Carriers to the International Space Station, the largest of the shuttle's cargo carriers, containing 15 spare pieces of equipment including two gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly and a spare latching end effector for the station's robotic arm. Atlantis will return to Earth a station crew member, Nicole Stott, who has spent more than two months aboard the orbiting laboratory. STS-129 is slated to be the final space shuttle Expedition crew rotation flight.
