Haze Silhouettes Against Titan Glow

A startling silhouette of Saturn is created in this NASA Cassini spacecraft portrait.

AST-27-2339 (20 July 1975) --- The Earth’s limb at sunrise and cloud silhouettes in the Southern Hemisphere, as photographed from the Apollo spacecraft during the joint U.S.-USSR Apollo-Soyuz Test Project mission. The photograph was taken at an altitude of 230 kilometers (143 statute miles) with a 70mm Hasselblad camera using medium-speed Ektachrome QX-807 type film.

Inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida, technicians lift the right aft motor segment – one of five segments that make up one of two solid rocket boosters for the agency’s Space Launch System (SLS) – onto an inspection stand on June 23, 2020. While in the RPSF, the boosters will be mated to the rocket’s two aft skirts before they are moved to the Vehicle Assembly Building for stacking on the mobile launcher. The boosters, manufactured by Northrop Grumman in Utah, recently arrived at Kennedy for processing ahead of the Artemis I launch. Together, the twin boosters provide more than 75 percent of the total SLS thrust at launch. The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and SLS as an integrated system ahead of crewed flights to the Moon.

This image was taken by the Imager for Mars Pathfinder (IMP) about one minute after sunset on Mars on Sol 21. The prominent hills dubbed "Twin Peaks" form a dark silhouette at the horizon, while the setting sun casts a pink glow over the darkening sky. The image was taken as part of a twilight study which indicates how the brightness of the sky fades with time after sunset. Scientists found that the sky stays bright for up to two hours after sunset, indicating that Martian dust extends very high into the atmosphere. http://photojournal.jpl.nasa.gov/catalog/PIA00783

NASA's Perseverance Mars rover used its Mastcam-Z camera to capture the silhouette of Phobos, one of the two Martian moons, as it passed in front of the Sun on Sept. 30, 2024, the 1,285th Martian day, or sol, of the mission. Perseverance has captured several Phobos transits since its landing at Mars' Jezero Crater in February 2021. By comparing the various recordings, scientists can refine their understanding of the potato-shaped moon's orbit, learning how it is changing. Eons from now, Phobos' orbit is expected to eventually send the moon toward the Red Planet's surface. Arizona State University leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets. A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

KENNEDY SPACE CENTER, FLA. -- The blue Florida sky helps silhouette space shuttle Atlantis as it hurtles into space on mission STS-122 to the International Space Station. Liftoff was on time at 2:45 p.m. EST. Below the nozzles of the main engines are the blue cones of light, known as shock or mach diamonds. They are a formation of shock waves in the exhaust plume of an aerospace propulsion system. The launch is the third attempt for Atlantis since December 2007 to carry the European Space Agency's Columbus laboratory to the International Space Station. During the 11-day mission, the crew's prime objective is to attach the laboratory to the Harmony module, adding to the station's size and capabilities. Photo credit: NASA/Jerry Cannon, Rusty Backer

Underneath is the crawler-transporter, which carries the multi-ton vehicles to the pad. In the grass behind the towering structures are two white herons. Columbia is scheduled to be launched Feb. 28 on mission STS-109, a Hubble Servicing Mission. The goal of the mission is to replace Solar Array 2 with Solar Array 3, replace the Power Control Unit, remove the Faint Object Camera and install the ACS, install the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) Cooling System, and install New Outer Blanket Layer insulation

The orbiter Atlantis makes the turn to the Orbiter Processing Facility bay 3 after being towed from the Shuttle Landing Facility. The unusual silhouette of the aft section on the orbiter is due to the tail cone covering the aft engines. Atlantis landed Feb. 19 at Edwards Air Force Base concluding mission STS-98. The orbiter returned to Florida on the back of a Shuttle Carrier Aircraft, known as a ferry flight, that began March 1. Unfavorable weather conditions kept it on the ground at Altus AFB, Okla., for several days until it could return to Florida. Atlantis will be prepared in the OPF for mission STS-104, the 10th construction flight to the International Space Station, scheduled to launch June 8

CAPE CANAVERAL, Fla. – The deep-red sunset sky puts Launch pad 39A in silhouette. Space shuttle Atlantis is on the pad. Atlantis’ October target launch date for the STS-125 Hubble Space Telescope servicing mission was delayed after a device on board Hubble used in the storage and transmission of science data to Earth shut down on Sept. 27. Replacing the broken device will be added to Atlantis’ servicing mission to the telescope. In the interim, Atlantis will be rolled back to the Vehicle Assembly Building until a new target launch date can be set for the mission in 2009. Photo credit: NASA/Troy Cryder

KENNEDY SPACE CENTER, Fla. -- As the sun clears the horizon, it creates a silhouette of the Space Shuttle Atlantis as it makes the crawl from the Vehicle Assembly Building to Launch Pad 39A. The Shuttle has been in the VAB undergoing tests on the solid rocket booster cables. A prior extensive evaluation of NASA’s SRB cable inventory on the shelf revealed conductor damage in four (of about 200) cables. Shuttle managers decided to prove the integrity of the system tunnel cables already on Atlantis, causing return of the Shuttle to the VAB a week ago. Launch of Atlantis on STS-98 has been rescheduled to Feb. 7 at 6:11 p.m. EST

KENNEDY SPACE CENTER, Fla. -- Dawn’s early light creates a powerful silhouette of the Space Shuttle Discovery on its mobile launcher platform as it creeps to Launch Pad 39B. Discovery is scheduled to launch Oct. 5 at 9:30 p.m. EDT on mission STS-92. Making the 100th Space Shuttle mission launched from Kennedy Space Center, Discovery will carry two pieces of hardware for the International Space Station, the Z1 truss, which is the cornerstone truss of the Station, and the third Pressurized Mating Adapter. Discovery also will be making its 28th flight into space, more than any of the other orbiters to date

This composite image shows suspected plumes of water vapor erupting at the 7 o’clock position off the limb of Jupiter’s moon Europa. The plumes, photographed by NASA’s Hubble’s Space Telescope Imaging Spectrograph, were seen in silhouette as the moon passed in front of Jupiter. Hubble’s ultraviolet sensitivity allowed for the features -- rising over 100 miles (160 kilometers) above Europa’s icy surface -- to be discerned. The water is believed to come from a subsurface ocean on Europa. The Hubble data were taken on January 26, 2014. The image of Europa, superimposed on the Hubble data, is assembled from data from the Galileo and Voyager missions.

KENNEDY SPACE CENTER, FLA. - Dark clouds silhouette Space Shuttle Atlantis as it rolls back to Launch Pad 39B atop the crawler-transporter. The shuttle had been moved off the launch pad due to concerns about the impact of Tropical Storm Ernesto, expected within 24 hours.
