Winter Frost and Fog

Chasma Australe Fog
Crater with Wavy Fog

Kennedy Space Center’s Vehicle Assembly Building (VAB) is partially obstructed by fog during the early morning on March 15, 2021. Built in 1966, the VAB remains a central hub for the Florida spaceport. The national landmark plays a major role in NASA’s plans to launch people and equipment deep into space on missions, including to the Moon in the Artemis program.

A fog rolls over the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on July 13, 2020. The iconic 525-foot-tall facility will support the launch of the agency’s Space Launch System rocket and Orion spaceport for Artemis missions. Under the Artemis program, NASA will send the first woman and next man to the Moon. Exploration Ground Systems is overseeing upgrades to the VAB. In view in the background is the Launch Control Center.

Fog is the only source of moisture for desert dwelling animals and plants living in the Namib Desert sand dune field, Namibia (23.5N, 15.0E). Coastal stratus clouds provide most of the life supporting moisture as fog droplets in this arid land where the usual annual rainfall is less than a quarter of an inch for decades at a time. In this view, the stratus clouds over the coast conform to the dune pattern proving that the fog is in ground contact.

A spider web hangs in the forefront of a sunrise at Kennedy Space Center on March 15, 2021. Kennedy shares space with the Merritt Island National Wildlife Refuge on Florida’s east coast. The refuge includes about 140,000 acres on land and water and provides a wide variety of habitats.
In this small section of the larger crescent image of Pluto, taken by NASA's New Horizons just 15 minutes after the spacecraft's closest approach on July 14, 2015, the setting sun illuminates a fog or near-surface haze, which is cut by the parallel shadows of many local hills and small mountains. The image was taken from a distance of 11,000 miles (18,000 kilometers), and the width of the image is 115 miles (185 kilometers). http://photojournal.jpl.nasa.gov/catalog/PIA19946

CAPE CANAVERAL, Fla. – Fog envelops the Cape Canaveral Lighthouse that has graced Cape Canaveral's shore for more than 100 years under the stewardship of the U.S. Air Force. The center shares a boundary with the refuge that includes salt-water estuaries, brackish marshes, hardwood hammocks and pine flatwoods. The diverse landscape provides habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. Photo credit: NASA/Jack Pfaller

STS-45 Atlantis, Orbiter Vehicle (OV) 104, lands on concrete runway 33 at the Kennedy Space Center's (KSC's) Shuttle Landing Facility (SLF). The main landing gear (MLG) touched down at 6:23:06 am (Eastern Standard Time (EST)) in the early morning Florida fog as seen in these views. The deployed nose landing gear (NLG) rides above the runway before wheel stop.

Two extremely bright stars illuminate a greenish mist in this image from the new GLIMPSE360 survey from NASA Spitzer Space Telescope. The fog is comprised of hydrogen and carbon compounds called polycyclic aromatic hydrocarbons.
The Surface Stereo Imager camera aboard NASA Phoenix Mars Lander acquired a series of images of the laser beam in the Martian night sky. Bright spots in the beam are reflections from ice crystals in the low level ice-fog.

Earth observation taken during a day pass by the Expedition 37 crew. Per Twitter message: Early morning fog in the river valleys of Ohio and West Virginia.

ISS030-E-062540 (2 Feb. 2012) --- This nighttime image, photographed by one of the members of the Expedition 30 crew from the International Space Station, features the Greater Chicago Metropolitan Area strung along the southwest shore of Lake Michigan. The region is partially covered by clouds, probably low-hanging, or even fog. Meteorologists say there is a fine line between low thin clouds and fog. Fog is not common in the Great Lakes area this time of the year (usually too windy), but this has been an exceptionally mild winter. The faint gold line of airglow—caused by ultraviolet radiation exciting the gas molecules in the upper atmosphere—parallels the horizon or Earth limb. Minor auroral activity (Borealis) is visible in upper right.

Low clouds filled California’s Central Valley in late January, 2015. Such winter fog is considered a common phenomenon, and can be so dense that it snarls traffic, causes fender-benders, and can make symptoms worse in those with respiratory disease. At the same time, the moist winter fog helps keep temperatures low in the rich agricultural region by reflecting sunlight and keeping the ground from warming, which helps keep the abundant fruit and nut trees dormant, allowing for bountiful harvests. Scientific studies have reported that winter fogs (also called Thule fogs) are occurring less frequently in the Central Valley. One study, by Dennis Baldocchi and Eric Waller, was published in May, 2014. It finds that since 1981 the number of fog days between November and February has decreased by 46 percent. The severe drought that California has experienced in recent years may also have decreased the number of fog events even more since 2012. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on January 24, 2015.

A thick blanket of low clouds covered the English Channel, Celtic Sea and Irish Sea on March 13, 2014. The fog also crept over major cities in the United Kingdom and Ireland. While citizens living in parts of Ireland, England, Wales, Scotland and Northern Ireland were posting ground-based photos of fog-shrouded landscape on social media, the internet and news outlets, the scene was also captured from space. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua captured this true-color image of the cloudy day at 13:00 UTC (1:00 p.m. in London) on that same day. The dense fog (low clouds) affected air travel, causing the cancellation of hundreds of flights going through London City Airport, where visibility was reported at less than 100 meters (328 ft) – less than the length of an American football field. Flights were also cancelled at Heathrow, Gatwick and Manchester. A private helicopter flying to Northern Ireland went down in by the fog near the Norfolk-Suffolk border, with loss of four lives. Driving was little better in many areas, causing the Met Office to issue a yellow weather warning and to caution drivers of difficult conditions. The lowest visibility of the day was reported at Roches Point weather station. Located at the southeastern tip of Cork Harbor, Ireland, the station reported visibility of less than 50 meters (164 ft) – the length of an Olympic size swimming pool. In this image, the fog-covered Celtic Sea is located in the southwest. Ireland lies under tendrils of low cloud in the northwest corner of the image. Banks of clouds part around England, near the center of the image, and southern Wales (top and center) completely under the foggy blanket. Fog also creeps over the coasts of France, Belgium and the Netherlands on the east side of the English Channel.

Despite the heavy ground fog in the lower valleys, this 70mm handheld camera's photo provides a strikingly detailed view of the Italian, Swiss and Austrian Alps of central Europe. For example, the famous Brenner Pass, an historic gateway connecting Italy to the rest of Europe, can be seen in the left central foreground. The Austrian city of Innsbruck on the Inn River, scene of the 1964 and 1976 Winter Olympics, and normally visible in great detail, is completely masked by heavy ground fog. Center coordinates of the pictured area are located at 47.5 degrees north latitude and 12.5 degrees east longitude.

CAPE CANAVERAL, Fla. - Fog settles around the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida three days before the planned liftoff of space shuttle Discovery on the STS-131 mission. Weather conditions for launch at 6:21 a.m. EDT on April 5 are very favorable except for the possibility of early morning fog. On STS-131, the seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with supplies, a new crew sleeping quarters and science racks that will be transferred to the International Space Station's laboratories. The crew also will switch out a gyroscope on the station’s truss, install a spare ammonia storage tank and retrieve a Japanese experiment from the station’s exterior. STS-131 is the 33rd shuttle mission to the station and the 131st shuttle mission overall.

CAPE CANAVERAL, Fla. – Fog envelopes the top of the 355-foot-tall Mobile Launcher at NASA's Kennedy Space Center in Florida. In 2013, the agency awarded a contract to J.P. Donovan Construction Inc. of Rockledge, Fla., to modify the launcher, or ML, one of the key elements of ground support equipment being upgraded by the Ground Systems Development and Operations Program office at Kennedy. The ML will carry the Space Launch System rocket, or SLS, and Orion spacecraft to Launch Pad 39B for its first mission, Exploration Mission-1, in 2017.

Like a lighthouse in the fog the luminous core of NGC 2768 slowly fades outwards to a dull white haze in this image taken by the NASA/ESA Hubble Space Telescope. NGC 2768 is an elliptical galaxy in the constellation of Ursa Major (The Great Bear). It is a huge bundle of stars, dominated by a bright central region, where a supermassive black hole feasts on a constant stream of gas and dust being fed to it by its galactic host. The galaxy is also marked by a prominent plume of dust reaching out from the centre and lying perpendicular to the galaxy’s plane. This dust conceals a symmetrical, s-shaped pair of jets that are being produced by the supermassive black hole as it feeds.

VANDENBERG AIR FORCE BASE, Calif. – NASA's Soil Moisture Active Passive mission, or SMAP, is scheduled to launch in November 2014 from Space Launch Complex 2 on Vandenberg Air Force Base in California, seen here on a temperate, fog-free summer's day. A United Launch Alliance Delta II rocket will be used to deliver SMAP into orbit. SMAP will provide global measurements of soil moisture and its freeze/thaw state. These measurements will be used to enhance understanding of processes that link the water, energy and carbon cycles, and to extend the capabilities of weather and climate prediction models. SMAP data also will be used to quantify net carbon flux in boreal landscapes and to develop improved flood prediction and drought monitoring capabilities.
