Description SAGE III Ozone Loss and Validation Experiment (SOLVE) NASA ER-2 # 809 and its DC-8 shown in Arena Arctica before the SAGE III Ozone Loss and Validation Experiment (SOLVE). The two airborne science platforms were based north of the Arctic Circle in Kiruna, Sweden, during the winter of 2000 to study ozone depletion as part of SOLVE. A large hangar built especially for research, "Arena Arctica" housed the instrumented aircraft and the scientists. Scientists have observed unusually low levels of ozone over the Arctic during recent winters, raising concerns that ozone depletion there could become more widespread as in the Antarctic ozone hole. The NASA-sponsored international mission took place between November 1999 and March 2000 and was divided into three phases. The DC-8 was involved in all three phases returning to Dryden between each phase. The ER-2 flew sample collection flights between January and March, remaining in Sweden from Jan. 9 through March 16. "The collaborative campaign will provide an immense new body of information about the Arctic stratosphere," said program scientist Dr. Michael Kurylo, NASA Headquarters. "Our understanding of the Earth's ozone will be greatly enhanced by this research."

Date 4/5/00
Description Polar stratospheric clouds over Kiruna, Sweden, on Jan. 27, 2000. The colorful appearance of these clouds is due to the small size of their droplets and their high altitude, approximately 21,300 meters (70,000 ft). The small droplets in the clouds result in separation of light of different colors due to refraction of sunlight. Their high altitude allows for full solar illumination for up to 20 minutes following sunset at the ground. These clouds, which have long been called "Mother of Pearl" by Scandinavians, participate in a chain of events that leads to ozone depletion by human-produced chlorine. Between November 1999 and March 2000, the SAGE III Ozone Loss and Validation Experiment (SOLVE) provided scientists with measurements of ozone using a variety of satellite-, airplane-, balloon- and ground-based instruments. Scientists also obtained a comprehensive inventory of numerous other atmospheric gases and information on the physical and chemical properties of polar stratospheric clouds. The SOLVE mission was co-sponsored by the Upper Atmosphere Research Program, Atmospheric Effects of Aviation Project, Atmospheric Chemistry Modeling and Analysis Program, and Earth Observing System of NASA's Earth Science Enterprise as part of the validation program for the SAGE III instrument. Based primarily in Kiruna, Sweden, the campaign included scientists from the United States, Europe, Canada, Russia and Japan. A key aspect to the success of this mission was the permission to fly both NASA research aircraft over Russia. SOLVE was managed by the Ames Research Center, Moffett Field, CA, with extensive participation by science teams from Goddard Space Flight Center, Greenbelt, MD, Langley Research Center, Hampton, VA, and the Jet Propulsion Laboratory, Pasadena, CA, as well as a number of other government laboratories and universities. The ER-2 and DC-8 aircraft are based at Dryden Flight Research Center, Edwards, CA, and the U.S. balloon operations in Sweden were conducted by a team from the National Scientific Balloon Facility, Palestine, TX.

Title A Grazing Encounter Between Two Spiral Galaxies
Full Description The larger and more massive galaxy is cataloged as NGC 2207 (on the left in the Hubble Heritage image), and the smaller one on the right is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light-years toward the right-hand edge of the image. Computer simulations, carried out by a team led by Bruce and Debra Elmegreen, demonstrate the leisurely timescale over which galactic collisions occur. In addition to the Hubble images, measurements made with the National Science Foundation's Very Large Array Radio Telescope in New Mexico reveal the motions of the galaxies and aid the reconstruction of the collision. The calculations indicate that IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient energy to escape from the gravitational pull of NGC 2207, and is destined to be pulled back and swing past the larger galaxy again in the future. The high resolution of the Hubble telescope image reveals dust lanes in the spiral arms of NGC 2207, clearly silhouetted against IC 2163, which is in the background. Hubble also reveals a series of parallel dust filaments extending like fine brush strokes along the tidally stretched material on the right-hand side. The large concentrations of gas and dust in both galaxies may well erupt into regions of active star formation in the near future. Trapped in their mutual orbit around each other, these two galaxies will continue to distort and disrupt each other. Eventually, billions of years from now, they will merge into a single, more massive galaxy. It is believed that many present-day galaxies, including the Milky Way, were assembled from a similar process of coalescence of smaller galaxies occurring over billions of years. This image was created from 3 separate pointings of Hubble. The Wide Field Planetary Camera 2 data sets were obtained by Debra Meloy Elmegreen (Vassar College), Bruce G. Elmegreen (IBM Research Division), Michele Kaufman (Ohio State U.), Elias Brinks (Universidad de Guanajuato, Mexico), Curt Struck (Iowa State University), Magnus Thomasson (Onsala Space Obs., Sweden), Maria Sundin (Goteborg University, Sweden), and Mario Klaric (Columbia, South Carolina).

Abstract Polar stratospheric clouds form at extremely low temperatures in the upper atmosphere. Should the temperature rise, clouds won't form. In this visualization, sequential temperature readings taken in the research area for SOLVE (Stratospheric Ozone Loss and Validation Experiment) are plotted against a threshold temperature for PSC formation. These are clouds essentially made of nitric acid. Note how the area covered by the clouds increases as winter progresses. The red point on the map indicates the location of Kiruna, Sweden, the SOLVE staging area.

Full Description The International Space Station (ISS) is an unparalleled international scientific and technological cooperative venture that will usher in a new era of human space exploration and research and provide benefits to people on Earth. On-Orbit assembly began on November 20, 1998, with the launch of the first ISS component, Zarya, on a Russian Proton rocket. The Space Shuttle followed on December 4, 1998, carrying the U.S.-built Unity cornecting Module. Sixteen nations are participating in the ISS program: the United States, Canada, Japan, Russia, Brazil, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland, and the United Kingdom. The ISS will include six laboratories and be four times larger and more capable than any previous space station. The United States provides two laboratories (United States Laboratory and Centrifuge Accommodation Module) and a habitation module. There will be two Russian research modules, one Japanese laboratory, referred to as the Japanese Experiment Module (JEM), and one European Space Agency (ESA) laboratory called the Columbus Orbital Facility (COF). The station's internal volume will be roughly equivalent to the passenger cabin volume of two 747 jets. Over five years, a total of more than 40 space flights by at least three different vehicles - the Space Shuttle, the Russian Proton Rocket, and the Russian Soyuz rocket - will bring together more than 100 different station components and the ISS crew. Astronauts will perform many spacewalks and use new robotics and other technologies to assemble ISS components in space.

A Danish Perspective
Title A Danish Perspective
Description high resolution 1000 pixel-wide image (600 KB JPEG) The Kingdom of Denmark, with an area of 16,639 square miles, consists of the Jutland Peninsula and roughly 500 islands. It is also a part of the generally fertile and mostly agricultural region known as the North European Plain. This entire region is generally flat to slightly rolling and is overlain with deposits of Pleistocene glaciers. (The Pleistocene lasted from 1.8 million to 11,000 years ago, during which time several ice ages occured.) Taking advantage of remarkably fair weather over north central Europe for this time of year, the crew of the International Space Station took this panoramic view that extends from the North Sea coast of the Netherlands on the left to the Baltic Sea shores of Sweden on the right. The late-winter landscape has little snow cover except over northeastern Germany, Sweden, and the rugged mountains of Norway. Such images, composed by astronauts, provide unique, synoptic perspectives of the Earth's geography and natural processes. Astronaut photograph ISS006-E-33901 [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS006&roll=E&frame=33901 ] was taken February 26, 2003, with an Electronic Still Camera equipped with 28 mm lens and is provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center. Additional images taken by astronauts and cosmonauts can be viewed at the NASA-JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ]

Title African Dust Reaches Northern Europe
Description On April 16, 2003, the Sea-viewing Wide Field-of-View Sensor (SeaWiFS) captured this image of African dust blowing far northward over Europe. The long trail of dust can be seen at bottom center arcing over the Pyrenees Mountains that separate Spain (south) from France (north). The trail stretches over the Atlantic Ocean and across Ireland (west) and Scotland, and continues eastward to Sweden and Norway, and then Denmark, to the south.

Heat Wave in Western Europe
Title Heat Wave in Western Europe
Description Western Europe continued to bake in late July 2006. Following an unusually warm spell between July 12 and 19, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13743 ] temperatures across most of the region remained much warmer than normal. This image shows land surface (as opposed to air) temperatures collected from July 20-27, 2006, compared to the average temperatures for that period over the past six years (2000-2005). Places that were up to ten degrees Celsius warmer than average are deep red, while places that were up to ten degrees cooler than average are deep blue. Places where the temperatures were average are white. The temperatures were measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. In the center of the image, deep red areas of very warm temperatures spread across Germany, as well as France (to the west), and Poland (to the east). To the north (top center), both Norway (west) and Sweden (east) were much warmer than average. Only small pockets of the region were cooler than average: northeastern Spain, the "toe" of Italy's boot and the western half of the island of Sicily, and parts of Greece (lower right). July 2006 was a record-breaking month for heat in many Western European countries, coming in as the hottest July on record in several countries, including Belgium, Denmark, Ireland, the Netherlands, and the United Kingdom.

EO-1 Launches!
Title EO-1 Launches!
Description These photos [view expanded images of launch (left) or view from above (right)] show the launch of the Boeing Delta II rocket from Vandenberg Air Force Base, CA, at 10:24 a.m. on November 21 PST, carrying a payload of three satellites into orbit. The payload included NASA's Earth Observer-1 (EO-1), Argentina's SAC-C, and Sweden's Munin spacecraft. Sixty minutes after lift-off, EO-1 was successfully deployed in orbit, SAC-C was deployed about 30 minutes later, and Munin deployed shortly after that. All three satellites are performing well. The launch of EO-1 marks the beginning of NASA's New Millennium Program (NMP), in which NASA is developing smaller, lighter spacecraft that meet or exceed the performance of current satellite technologies. The goal of NMP is to improve the on-orbit measurement capabilities of satellites while reducing the cost to build and launch them into space. Because its purpose is to demonstrate new technology on orbit, data from EO-1 will be made available only after the team completes its calibration and validation activities. Over the next two weeks, EO-1 and SAC-C will gradually be moved into their final orbital trajectories--flying very nearly from pole to pole at an altitude of 705 kilometers. The objective is to fly them in formation with Landsat 7 and Terra, two of NASA's Earth Observing System (EOS) satellites already in orbit, so that their data may be cross compared for calibration and validation purposes. EO-1 will follow about 60 seconds behind Landsat 7, descending southward across the equator at about 10:16 a.m. local time. For more information see: * ?

Title Noctilucent Clouds Over Sweden
Explanation Sometimes it's night on the ground but day in the air. As the Earth rotates to eclipse the Sun, sunset [ http://antwrp.gsfc.nasa.gov/apod/ap060712.html ] rises up from the ground. Therefore, at sunset on the ground, sunlight still shines on clouds [ http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/home.rxml ] above. Under usual circumstances, a pretty sunset [ http://antwrp.gsfc.nasa.gov/apod/ap980526.html ] might be visible, but unusual noctilucent clouds [ http://lasp.colorado.edu/noctilucent_clouds/ ] float so high up they can be seen well after dark. Pictured above [ http://www.clearskies.se/NLC%2016.htm ] last month, a network of noctilucent clouds [ http://science.nasa.gov/headlines/y2003/19feb_nlc.htm ] cast a colorful but eerie glow after dusk near Vallentuna [ http://en.wikipedia.org/wiki/Vallentuna ], Sweden [ http://en.wikipedia.org/wiki/Sweden ]. Although noctilucent clouds [ http://en.wikipedia.org/wiki/Noctilucent_clouds ] are thought to be composed of small ice-coated particles, much remains unknown [ http://www.nlcnet.co.uk/ ] about them. Recent evidence [ http://www.nrl.navy.mil/pressRelease.php?Y=2003&R=35-03r ] indicates that at least some noctilucent clouds [ http://www.gsfc.nasa.gov/topstory/2003/0522shuttleshine.html ] result from freezing water exhaust from Space Shuttle [ http://antwrp.gsfc.nasa.gov/apod/ap021023.html ]s.
A Leonid Meteor Over Sweden
Title A Leonid Meteor Over Sweden
Explanation This past weekend, small remnant bits of a distant comet lit up the skies over much of planet Earth. Incoming reports [ http://lists.meteorobs.org/pipermail/meteorobs/2006-November/date.html ], however, have this year's Leonid meteor shower [ http://meteorshowersonline.com/leonids.html ] as less active than Leonid meteor showers a few years ago [ http://antwrp.gsfc.nasa.gov/apod/ap021117.html ]. Nevertheless, some sky enthusiasts [ http://antwrp.gsfc.nasa.gov/apod/ap040808.html ] reported peak meteor [ http://spaceweather.com/meteors/gallery_19nov06.html ] bursts as high as one visual meteor per minute. The parent body of the Leonids meteor shower, Comet Tempel-Tuttle [ http://antwrp.gsfc.nasa.gov/apod/ap021116.html ], leaves a trail of expelled sand-size particles every 33 years when it returns to the inner Solar System. When the Earth passes through a stream of these Sun-orbiting particles, a meteor shower results. Pictured above [ http://www.clearskies.se/Leonid%20meteor.htm ], a Leonid meteor was captured two days ago during the early morning hours of November 19 over Vallentuna [ http://en.wikipedia.org/wiki/Vallentuna ], Sweden [ http://en.wikipedia.org/wiki/Sweden ]. Although activity levels in meteor showers are notoriously hard to predict, some astronomers speculate that Aurigids [ http://comets.amsmeteors.org/meteors/showers/aurigids.html ] meteor shower next September might [ http://www.space.com/spacewatch/060817_meteor_shower.html ] be unusually rich in bright meteors [ http://antwrp.gsfc.nasa.gov/apod/ap011119.html ].

Title Upgrading the International Space Station
Explanation The International Space Station [ http://www.shuttlepresskit.com/ISS_OVR/index.htm ] (ISS) will be the largest human-made object ever to orbit [ http://hyperphysics.phy-astr.gsu.edu/hbase/orbv.html ] the Earth [ http://antwrp.gsfc.nasa.gov/apod/ap010204.html ]. The station [ http://www.shuttlepresskit.com/ISS_OVR/orbit_assembly.htm ] is so large that it could not be launched [ http://antwrp.gsfc.nasa.gov/apod/ap010723.html ] all at once -- it is being built piecemeal [ http://spaceflight.nasa.gov/gallery/images/station/assembly/ndxpage1.html ] with large sections added continually by flights of the Space Shuttle [ http://antwrp.gsfc.nasa.gov/apod/ap990411.html ]. To function, the ISS needs trusses [ http://www.nasa.gov/mission_pages/station/structure/elements/its.html ] to keep it rigid and to route electricity [ http://www.sciencemadesimple.com/static.html ] and liquid coolants. These trusses [ http://spaceflight.nasa.gov/station/assembly/elements/its/ ] are huge, extending over 15 meters long, and with masses over 10,000 kilograms. Pictured above [ http://spaceflight.nasa.gov/gallery/images/shuttle/sts-116/html/s116e05983.html ] earlier this month, astronauts [ http://liftoff.msfc.nasa.gov/academy/astronauts/wannabe.html ] Robert L. Curbeam [ http://www.jsc.nasa.gov/Bios/htmlbios/curbeam.html ] (USA) and Christer Fuglesang [ http://www.jsc.nasa.gov/Bios/htmlbios/fuglesan.html ] (Sweden) work to attach a new truss segment [ http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts116/news/STS-116-07.html ] to the ISS and begin to upgrade the power grid.

Explanation The tantalizing Pleiades [ http://antwrp.gsfc.nasa.gov/apod/ap071122.html ] star cluster seems to lie just beyond the trees above a dark castle tower [ http://www.twanight.org/newTWAN/photos.asp?ID=3001176 ] in this dramatic view [ http://www.clearskies.se/Castle%20ruin%20and%20Holmes.htm ] of The World at Night [ http://www.twanight.org/ ]. Recorded earlier this month, the starry sky also features bright star Aldebaran [ http://www.astro.uiuc.edu/~kaler/sow/ aldebaran.html ] below the Pleiades and a small, faint, fuzzy cloud otherwise known as Comet Holmes [ http://antwrp.gsfc.nasa.gov/apod/ap071121.html ] near picture center at the top of the field. Starry Night Castle might be [ http://antwrp.gsfc.nasa.gov/apod/ap050218.html ] an appropriate name for the medieval castle ruin in the foreground. But its traditional name is Mörby Castle [ http://www.castlesontheweb.com/photoarchive/ index.php?action=album&id=1421&sessionid= ], found north of Stockholm, near lake Skedviken in Norrtälje, Sweden.

Title 7,000 Stars And The Milky Way
Explanation This panorama view of the sky [ http://antwrp.gsfc.nasa.gov/apod/lib/sky.html ] is really a drawing. It was made in the 1940s under the supervision of astronomer Knut Lundmark at the Lund Observatory [ http://nastol.astro.lu.se/~eva/geneng.html ] in Sweden. To create the picture, draftsmen used a mathematical distortion to map the entire sky onto an oval shaped image with the plane of our Milky Way Galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap950908.html ] along the center and the north galactic pole at the top. 7,000 individual stars are shown as white dots, size indicating brightness. The "Milky Way" clouds, actually the combined light of dim, unresolved stars in the densely populated galactic plane, are accurately painted on, interrupted by dramatic dark dust lanes [ http://antwrp.gsfc.nasa.gov/apod/ap951109.html ]. The overall effect is photographic in quality and represents the visible sky. Can you identify any familiar landmarks or constellations? For starters, Orion [ http://antwrp.gsfc.nasa.gov/apod/ap951114.html ] is at the right edge of the picture, just below the galactic plane and the Large [ http://antwrp.gsfc.nasa.gov/apod/ap950918.html ] and Small Magellanic Clouds [ http://antwrp.gsfc.nasa.gov/apod/ap950919.html ] are visible as fuzzy patches in the lower right quadrant.
