ISS034-E-009486 (19 Dec. 2012) --- Though somewhat faint, the contrails from the launch of the Expedition 34/35 crew onboard the Soyuz TMA-07M on Dec. 19 are recognizable  while the International Space Station and its three-man Expedition 34 crew were over the Caspian Sea. The skies were clear over the Baikonur Cosmodrome at this time, making it possible that these contrail "clouds" would be easy to spot.

ISS004-E-11807 (15 May 2002) --- This digital photograph, taken through the windows of the International Space Station on May 15, 2002, shows condensation trails over the Rh&#0244;ne Valley in the region west of  Lyon, France.  Condensation trails-or contrails-are straight lines of ice crystals that form in the wake of jet liners where air temperatures are lower than about -40 degrees Centigrade.  Scientists have observed that newer contrails are thin whereas older trails have widened with time as a result of light winds. Because of this tendency for thin contrails to cover greater areas with time, it is estimated that these &#0147;artificial clouds&#0148; cover 0.1 per cent of the planet&#0146;s surface.  Percentages are far higher in some places, say the scientists, such as southern California, the Ohio River Valley and parts of Europe, as illustrated here. The climatic impact of such clouds is poorly understood, which is why scientists continue to study them using images such as this.

The STS-28 insignia was designed by the astronaut crew, who said it portrays the pride the American people have in their manned spaceflight program. It depicts America (the eagle) guiding the space program (the Space Shuttle) safely home from an orbital mission. The view looks south on Baja California and the west coast of the United States as the space travelers re-enter the atmosphere. The hypersonic contrails created by the eagle and Shuttle represent the American flag. The crew called the simple boldness of the design symbolic of America's unfaltering commitment to leadership in the exploration and development of space.

KENNEDY SPACE CENTER, FLA. --  Under blue sky streaked with contrails, Space Shuttle Atlantis, atop the mobile launcher platform, is being rolled back to the Vehicle Assembly Building (at left in the background) from Launch Pad 39A.  In the VAB, the shuttle will be examined for hail damage.  A severe thunderstorm with golf ball-sized hail caused divots in the giant tank's foam insulation and minor surface damage to about 26 heat shield tiles on the shuttle's left wing. Further evaluation of the tank is necessary to get an accurate accounting of foam damage and determine the type of repair required and the time needed for that work.  A new target launch date has not been determined, but teams will focus on preparing Atlantis for liftoff in late April.  Photo credit: NASA/Amanda Diller

ISS040-E-006271 (31 May 2014) --- One of the Expedition 40 crew members aboard the Earth-orbiting International Space Station captured this panoramic image of South Africa on May 31, 2014. A combination of contrails and a bit of winter mist appears to have formed alphabetic and/or numeric characters in the upper right near the horizon. Sun glint off the south coast is slightly confusing as it is similar in brightness to the west-coast cloud cover, where an Atlantic storm rolls in. The Cape Fold Mountains cross the center of the view, going east from the Cape Town region (clouds obscure the Cape peninsula which normally serves as an icon for this part of Africa). A popular winegrowing region attributable to the Mediterranean climate is the area around Cape Town near lower left. Witwatersrand lies at the top of the picture obscured by the seemingly ever-present winter smoke and smog. The Orange River valley appears as a dark, nearly horizontal line at left.

STS103-501-104 (19-27 December 1999) ---  One of the astronauts aboard the Earth-orbiting Space Shuttle Discovery used a handheld large format camera to photograph this scene which stretches from the Gulf of Mexico into Oklahoma.   Parts of Louisiana and Arkansas are also visible in the frame. The Red River snakes its way through the East Texas Piney Woods (center). The river meets with the southern edge of the Ouachita folded mountains of southern Oklahoma.  The white, linear feature north of the Red River is most likely a jet stream cloud, according to Earth scientists who studied the STS-103 collection at the Johnson Space Center (JSC).  Jet contrails can be seen flying over the clouds.  Along the Texas Gulf Coast are Galveston Bay and the greater Houston  metropolitan area.

Visualization Date 2003-12-18  Clouds ripple over Ireland and Scotland in a wave pattern, similar to the pattern of waves along a seashore. The similarity is not coincidental — the atmosphere behaves like a fluid, so when it encounters an obstacle, it must move around it. This movement forms a wave, and the wave movement can continue for long distances. In this case, the waves were caused by the air moving over and around the mountains of Scotland and Ireland. As the air crested a wave, it cooled, and clouds formed. Then, as the air sank into the trough, the air warmed, and clouds did not form. This pattern repeated itself, with clouds appearing at the peak of every wave.  Other types of clouds are also visible in the scene. Along the northwestern and southwestern edges of this true-color image from December 17, 2003, are normal mid-altitude clouds with fairly uniform appearances. High altitude cirrus-clouds float over these, casting their shadows on the lower clouds. Open- and closed-cell clouds formed off the coast of northwestern France, and thin contrail clouds are visible just east of these. Contrail clouds form around the particles carried in airplane exhaust. Fog is also visible in the valleys east of the Cambrian Mountains, along the border between northern/central Wales and England. This is an Aqua MODIS image.

KENNEDY SPACE CENTER, FLA. -  Nearly obscured by its own contrail, Space Shuttle Atlantis hurtles toward space for a rendezvous with the International Space Station on mission STS-115.  Liftoff was on-time at 11:14:55 a.m. EDT.  After launch attempts were scrubbed Aug. 27 and 29 and Sept. 3 and 8 due to weather and technical concerns,  this launch was executed perfectly.  Mission STS-115 is the 116th space shuttle flight, the 27th flight for orbiter Atlantis, and the 19th U.S. flight to the International Space Station. During the mission, Atlantis' astronauts will deliver and install the 17.5-ton, bus-sized P3/P4 integrated truss segment on the station. The girder-like truss includes a set of giant solar arrays, batteries and associated electronics and will provide one-fourth of the total power-generation capability for the completed station. STS-115 is scheduled to last 11 days with a planned landing at KSC. Photo credit: NASA/Ken Thornsley

CAPE CANAVERAL, Fla. -- Vapor trails follow space shuttle Endeavour as it approaches Runway 15 on the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida for the final time. A vapor trail, known as a contrail, is a cloud of water vapor that condenses and freezes around the small particles in aircraft exhaust. Main gear touchdown was at 2:34:51 a.m. EDT, followed by nose gear touchdown at 2:35:04 a.m., and wheelstop at 2:35:36 a.m. On board are STS-134 Commander Mark Kelly, Pilot Greg H. Johnson, and Mission Specialists Mike Fincke, Drew Feustel, Greg Chamitoff and the European Space Agency's Roberto Vittori.    STS-134 delivered the Alpha Magnetic Spectrometer-2 (AMS) and the Express Logistics Carrier-3 (ELC-3) to the International Space Station. AMS will help researchers understand the origin of the universe and search for evidence of dark matter, strange matter and antimatter from the station. ELC-3 carried spare parts that will sustain station operations once the shuttles are retired from service. STS-134 was the 25th and final flight for Endeavour, which has spent 299 days in space, orbited Earth 4,671 times and traveled 122,883,151 miles. Photo credit: NASA/Kevin O'Connell

S88-40309 (7 Nov. 1988) --- The STS-28 insignia was designed by the astronaut crew, who said it portrays the pride the American people have in their manned spaceflight program. It depicts America (the eagle) guiding the space program (the space shuttle) safely home from an orbital mission. The view looks south on Baja California and the west coast of the United States as the space travelers re-enter the atmosphere. The hypersonic contrails created by the eagle and shuttle represent the American flag. The crew called the simple boldness of the design symbolic of America's unfaltering commitment to leadership in the exploration and development of space. Crew members for STS-28 are astronauts Brewster H. Shaw Jr.,commander; Richard N. Richards, pilot; and David C. Leestma, Mark N. Brown and James C.  Adamson, mission specialists.     The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA

There’s more than one way to study the impact of biofuels. For NASA scientists, it means trailing an aircraft from as little as 300 feet behind while flying 34,000 feet in the air. Earlier this year, a NASA-led team conducted a series of carefully choreographed flights over California in order to sniff out how aircraft emissions differ when using petroleum fuels or biofuels. Early results from the Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS II) experiment confirm that blended biofuel is the cleaner-burning fuel.  &quot;Our findings show we definitely see a 50 percent reduction in soot emissions from the DC-8 when it burns the blended fuel as opposed to jet fuel alone,&quot; said Bruce Anderson, ACCESS principal investigator from NASA's Langley Research Center.  The DC-8 is a NASA science workhorse: a flying laboratory equipped to collect—or, in this case, produce—data for basic Earth science research. During the ACESS experiment, scientists took advantage of the aircraft's segregated fuel tank. On the fly, the pilot switched the fuel type sent to each of the four engines. The engines burned either jet fuel, or a 50-50 blend of jet fuel and a renewable alternative produced from camelina plant oil. With each change of fuel, three other instrumented aircraft took turns lining up in the DC-8's wake and flying anywhere from 90 meters (300 feet) to more than 30 kilometers (20 miles) behind to catch a sniff.  Richard Moore, a post-doctoral fellow at NASA Langley, took this photograph with a DSLR camera on May 7, 2014, during an ACCESS II test flight over Edwards Air Force Base in California. The photo was taken from Langley's HU-25C Guardian jet as it descended toward NASA's Armstrong Flight Research Center after a successful three-hour sampling flight behind the DC-8. The aircraft trailing the DC-8 in the photo was a Falcon 20-E5 jet owned by the German Aerospace Center.  The flight on May 7 was just the first in a series of flights that lasted throughout the month. After the campaign, researchers continued to examine the data to determine whether a reduction in soot emissions translates to a reduction in contrail formation, and how that might affect climate.

ISS023-E-035670 (8 May 2010) --- Mingachevir Reservoir, Azerbaijan is featured in this image photographed by an Expedition 23 crew member on the International Space Station. This detailed photograph highlights the southern Mingachevir Reservoir located in north-central Azerbaijan. The Mingachevir Reservoir occupies part of the Kura Basin, a topographic depression located between the Greater Caucasus Mountains to the northeast and the Lesser Caucasus Mountains to the southwest. According to scientists, folded layers of relatively young (less than 5.3 million years old) sedimentary rock, explosive volcanic products (ash and tuff), and unconsolidated sediments form the gray hills along the northern and southern shorelines of the reservoir (center and right). Afternoon sun highlights distinctive parallel patterns in the hills that are the result of water and wind erosion of different stratigraphic layers exposed at the surface. The nearby city of Mingachevir (left) is split by the Kur River after it passes through the dam and hydroelectric power station complex at top center. The current city was built in support of the hydroelectric power station constructed as part of the then Soviet Union?s energy infrastructure for the region. Today, Mingachevir is the fourth largest city in Azerbaijan (by population) and has become a cultural and economic center of the country. The reservoir held approximately 15 billion cubic meters of water at the time this image was taken, with a total engineered capacity of 16 billion cubic meters. The width of the reservoir illustrated here is approximately 8 kilometers; a jet flying over the reservoir and its contrail are visible midway between the opposing shorelines.
