Apart from a few aspects of this experience, The Kennedy Space Center was brilliant. The narrative is fantastic, the lighting clever and at times, the reveal of the exhibits breath-taking.
NASA has started an airborne science campaign to get a better understanding of what affects the composition of the atmosphere and the climate. The project is using specially equipped research planes.
NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth.
When NASA's Aqua satellite passed over Tropical Cyclone Iggy on Feb. 1 at 1805 UTC (1:05 p.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument aboard captured an infrared look at the cyclone. AIRS data showed that the strongest thunderstorms (with the coldest cloud top temperatures) had been pushed to the southeast of Iggy's center. That convection was pushed by vertical wind shear from the northwest. Once convection is pushed away from a tropical cyclone's center, the storm begins to fall apart. Tropical cyclones must be stacked in the atmosphere like a haystack. If the middle (convection in this case) gets pushed out, then the storm collapses.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite captured a true color image of Iggy when it passed overhead on Feb. 2, 2012 at 0615 UTC (1:15 a.m. EST). The MODIS image clearly shows how the wind shear is affecting the tropical depression because Iggy appears elongated from northwest to southeast, which is the direction of the wind shear.
The Australian Bureau of Meteorology (ABM) issued severe weather warnings for residents from Kalbarri to Morawa, and from Morawa to Wongan Hills; and Wongan to Narrogin and Harvey. The ABM website noted that the warning includes people in, near or between the following towns: Geraldton, Jurien Bay, Perth, Mandurah, York and Narrogin. Those areas can expect thunderstorms with heavy rainfall, and gusty winds as Iggy continues moving east. Flash flooding is also a possibility from the heavy rainfall.
On February 2, 2012, Tropical Depression Iggy had maximum sustained winds near 30 knots (~35 mph/~56 kph). It was located about 170 nautical miles (~196 miles/~315 km) northwest of Perth, Western Australia, and its center was near 29.9 South latitude and 114.2 East longitude. Iggy was moving to the east at 14 knots (16 mph/~26 kph) and is expected to continue in that direction making landfall before 0300 UTC on February 3, 2012 (or before 10 p.m. EST, Feb. 3). Iggy is expected to quickly weaken to a remnant low as it moves further inland in Western Australia.

Connecting the Pipe Nebula to the colorful region near bright star Antares is a dark cloud dubbed the Dark River, flowing from the picture's left edge. Murky looking, the Dark River's appearance is caused by dust obscuring background starlight, although the dark nebula contains mostly hydrogen and molecular gas. Surrounded by dust, Antares, a red supergiant star, creates an unusual bright yellowish reflection nebula. Above it, bright blue double star Rho Ophiuchi is embedded in one of the more typical bluish reflection nebulae, while red emission nebulae are also scattered around the region. Globular star cluster M4 is just seen above and right of Antares, though it lies far behind the colorful clouds, at a distance of some 7,000 light-years. The Dark River itself is about 500 light years away. The colorful skyscape is a mosaic of telescopic images spanning nearly 10 degrees (20 Full Moons) across the sky in the constellation of the Scorpion (Scorpius). via NASA ift.tt/1B3A4ZG
A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, the remarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotates across the Sun and out of view in the coming days its activity is difficult to forecast. But the timing of solar eclipses is easier to predict. The next will be a total solar eclipse on March 20, 2015. via NASA ift.tt/1skb2KM

Taking part in the Safari 2000 project in Pietersburg, South Africa
SAFARI 2000 – Pietersberg, 2000
The Southern African Regional Science Initiative (SAFARI 2000) project was an international science initiative to study the linkages between land and atmosphere processes conducted from 1999-2001 in the southern African region. In addition, SAFARI 2000 examined the relationship of biogenic, pyrogenic, and anthropogenic emissions and the consequences of their deposition to the functioning of the biogeophysical and biogeochemical systems of southern Africa.
During September 2000 NASA flew an ER-2 out of Polokwane, also known as Pietersburg. The ER2 carried a number of imaging instruments and was accompanied by low level in situ measurements conducted from a University of Washington C-580. Flying took place over South Africa, Namibia, Botswana, Mozambique and Zambia. The project was supported and supplied by a USAF C-141 and K -135 from March AFB. The single seater ER-2 flew across the Atlantic from Recife Brazil.

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990. Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. The nebula is a favorite target for amateur and professional astronomers. It is shadowy in optical light. It appears transparent and ethereal when seen at infrared wavelengths. The rich tapestry of the Horsehead Nebula pops out against the backdrop of Milky Way stars and distant galaxies that easily are visible in infrared light. Hubble has been producing ground-breaking science for two decades. During that time, it has benefited from a slew of upgrades from space shuttle missions, including the 2009 addition of a new imaging workhorse, the high-resolution Wide Field Camera 3 that took the new portrait of the Horsehead.

NASA has built and is sending a set of high-tech legs up to the International Space Station for Robonaut 2 (R2), the station's robotic crewmember. The new legs are scheduled to launch on the SpaceX-3 commercial cargo flight to the International Space Station, scheduled to launch Monday, April 14 at 4:58 p.m. EDT from Cape Canaveral Air Force Station in Florida. These new legs, funded by NASA's Human Exploration and Operations and Space Technology mission directorates, will provide R2 the mobility it needs to help with regular and repetitive tasks inside and outside the space station. The goal is to free up the crew for more critical work, including scientific research. Once the legs are attached to the R2 torso, the robot will have a fully extended leg span of nine feet, giving it great flexibility for movement around the space station. Each leg has seven joints and a device on what would be the foot, called an "end effector," which allows the robot to take advantage of handrails and sockets inside and outside the station. A vision system for the end effectors also will be used to verify and eventually automate each limb's approach and grasp. > Read more Image Credit: NASA via NASA 1.usa.gov/1yHsse2
Check this out from NASA -- This close-up from the Mars Reconnaissance Orbiter's HiRISE camera shows weathered craters and windblown deposits in southern Acidalia Planitia. A striking shade of blue in standard HiRISE image colors, to the human eye the area would probably look grey or a little reddish. But human eyes have not gazed across this terrain, unless you count the eyes of NASA astronauts in the scifi novel The Martian by Andy Weir. The novel chronicles the adventures of Mark Watney, an astronaut stranded at the fictional Mars mission Ares 3 landing site corresponding to the coordinates of this cropped HiRISE frame. For scale Watney's 6-meter-diameter habitat at the site would be about 1/10th the diameter of the large crater. Of course, the Ares 3 landing coordinates are only about 800 kilometers north of the (real life) Carl Sagan Memorial Station, the 1997 Pathfinder landing site. (go.nasa.gov/2ZEWoH2)

This new NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away. As seen in this image, the disk of IC 335 appears edge-on from the vantage point of Earth. This makes it harder for astronomers to classify it, as most of the characteristics of a galaxy’s morphology — the arms of a spiral or the bar across the center — are only visible on its face. Still, the 45 000 light-year-long galaxy could be classified as an S0 type. These lenticular galaxies are an intermediate state in galaxy morphological classification schemes between true spiral and elliptical galaxies. They have a thin stellar disk and a bulge, like spiral galaxies, but in contrast to typical spiral galaxies they have used up most of the interstellar medium. Only a few new stars can be created out of the material that is left and the star formation rate is very low. Hence, the population of stars in S0 galaxies consists mainly of aging stars, very similar to the star population in elliptical galaxies. As S0 galaxies have only ill-defined spiral arms they are easily mistaken for elliptical galaxies if they are seen inclined face-on or edge-on as IC 335 here. And indeed, despite the morphological differences between S0 and elliptical class galaxies, they share some common characteristics, like typical sizes and spectral features. Both classes are also deemed "early-type" galaxies, because they are evolving passively. However, while elliptical galaxies may be passively evolving when we observe them, they have usually had violent interactions with other galaxies in their past. In contrast, S0 galaxies are either aging and fading spiral galaxies, which never had any interactions with other galaxies, or they are the aging result of a single merger between two spiral galaxies in the past. The exact nature of these galaxies is still a matter of debate. European Space Agency Credit: ESA/Hubble and NASA via NASA ift.tt/1xheUp6

Barred spiral galaxy NGC 2903 is only some 20 million light-years distant. Popular among amateur astronomers, it shines in the northern spring constellation Leo, near the top of the lion's head. That part of the constellation is sometimes seen as a reversed question mark or sickle. One of the brighter galaxies visible from the northern hemisphere, NGC 2903 is surprisingly missing from Charles Messier's catalog of lustrous celestial sights. This colorful image from a small ground-based telescope shows off the galaxy's gorgeous spiral arms traced by young, blue star clusters and pinkish star forming regions. Included are intriguing details of NGC 2903's bright core, a remarkable mix of old and young clusters with immense dust and gas clouds. In fact, NGC 2903 exhibits an exceptional rate of star formation activity near its center, also bright in radio, infrared, ultraviolet, and x-ray bands. Just a little smaller than our own Milky Way, NGC 2903 is about 80,000 light-years across. via NASA ift.tt/1HXGmZK
