This is an artist's concept of the Research and Applications Modules (RAM). Evolutionary growth was an important consideration in space station plarning, and another project was undertaken in 1971 to facilitate such growth. The RAM study, conducted through a Marshall Space Flight Center contract with General Dynamics Convair Aerospace, resulted in the conceptualization of a series of RAM payload carrier-sortie laboratories, pallets, free-flyers, and payload and support modules. The study considered two basic manned systems. The first would use RAM hardware for sortie mission, where laboratories were carried into space and remained attached to the Shuttle for operational periods up to 7 days. The second envisioned a modular space station capability that could be evolved by mating RAM modules to the space station core configuration. The RAM hardware was to be built by Europeans, thus fostering international participation in the space program.
iss049e045458 (10/24/2016) --- Photographic documentation of Radiation Area Monitor (RAM) deployed in the Quest Airlock of the International Space Station (ISS). The Radiation Area Monitor (RAM) is a small set of thermoluminescent detectors encased in Lexan plastic that respond to radiation; the amount of radiation they absorb can be revealed by applying heat and measuring the amount of visible light released. The RAM is used to monitor dose and dose equivalent within the habitable volume of the International space Station (ISS) as a function of location, due to its predicted low sensitivity to high-Linear Energy Transfer radiation (neutrons and alpha particles).

This image combines NASA/ESA Hubble Space Telescope observations with data from the Chandra X-ray Observatory. As well as the electric blue ram pressure stripping streaks seen emanating from ESO 137-001, a giant gas stream can be seen extending towards the bottom of the frame, only visible in the X-ray part of the spectrum. Credit: NASA, ESA, CXC The spiral galaxy ESO 137-001 looks like a dandelion caught in a breeze in this new Hubble Space Telescope image. The galaxy is zooming toward the upper right of this image, in between other galaxies in the Norma cluster located over 200 million light-years away. The road is harsh: intergalactic gas in the Norma cluster is sparse, but so hot at 180 million degrees Fahrenheit that it glows in X-rays. The spiral plows through the seething intra-cluster gas so rapidly – at nearly 4.5 million miles per hour — that much of its own gas is caught and torn away. Astronomers call this "ram pressure stripping." The galaxy’s stars remain intact due to the binding force of their gravity. Tattered threads of gas, the blue jellyfish-tendrils trailing ESO 137-001 in the image, illustrate the process. Ram pressure has strung this gas away from its home in the spiral galaxy and out over intergalactic space. Once there, these strips of gas have erupted with young, massive stars, which are pumping out light in vivid blues and ultraviolet. The brown, smoky region near the center of the spiral is being pushed in a similar manner, although in this case it is small dust particles, and not gas, that are being dragged backwards by the intra-cluster medium.

This diagram depicts conditions observed by NASA's Cassini spacecraft during a flyby in Dec. 2013, when Saturn's magnetosphere was highly compressed, exposing Titan to the full force of the solar wind. In analyzing data from the encounter, scientists with Cassini's magnetometer team observed that the giant moon interacted with the solar wind much like the planets Mars and Venus, or a comet -- none of which possess their own internal magnetic field. Specifically, they saw that the solar wind draped itself around Titan, creating a shockwave that formed around Titan where the full-force solar wind rammed into the moon's atmosphere. Previously, researchers had thought Titan would have a different sort of interaction with the solar wind because of the moon's complex atmospheric chemistry. http://photojournal.jpl.nasa.gov/catalog/PIA19055
Flight engineer and photographer William Wynne (pictured) worked with photographer Arthur Laufman to execute a photo concept devised by Laufman. Wynne printed two copies of the F-61 aircraft in flight. The prints were made to the correct size that allowed them to be cut out and taped to the lenses of his goggles to simulate a reflection. The photo of Wynne was then taken with an out of focus background to simulate clouds.
On Sunday, February 3, roughly 800 million eyes from all over the world focused on the Louisiana Superdome in New Orleans as the New England Patriots battled the St. Louis Rams for the NFL Championship in Super Bowl XXXVI. This true color image of New Orleans was acquired on April 26, 2000, by the Enhanced Thematic Mapper plus (ETM+), flying aboard the Landsat 7 satellite. Lake Pontchartrain borders the city to the north. The big river winding its way east to west through the image is the Mississippi. The Louisiana Superdome, built in 1975, sits just inside the rightmost portion of the big river bend that cradles downtown New Orleans. The city, however, may not be around to hold a Super Bowl in 2102. New Orleans is slowly sinking into the Gulf of Mexico. The construction of flood walls and dams north of New Orleans over the past century have prevented sediments carried by the Mississippi River from reaching New Orleans and the Mississippi River Delta. Before the dams were built, river sediments would empty out onto the delta adding layer upon layer of new soil each year. The additional soil prevented the Gulf from subsuming the delta. Unless drastic measures are taken, the city and the delta could be awash in seawater by the end of this century.

An artist's rendering of the air-breathing, hypersonic X-43B, the third and largest of NASA's Hyper-X series flight demonstrators, which could fly later this decade. Revolutionizing the way we gain access to space is NASA's primary goal for the Hypersonic Investment Area, managed for NASA by the Advanced Space Transportation Program at the Marshall Space Flight Center in Huntsville, Alabama. The Hypersonic Investment area, which includes leading-edge partners in industry and academia, will support future generation reusable vehicles and improved access to space. These technology demonstrators, intended for flight testing by decade's end, are expected to yield a new generation of vehicles that routinely fly about 100,000 feet above Earth's surface and reach sustained speeds in excess of Mach 5 (3,750 mph), the point at which "supersonic" flight becomes "hypersonic" flight. The flight demonstrators, the Hyper-X series, will be powered by air-breathing rocket or turbine-based engines, and ram/scramjets. Air-breathing engines, known as combined-cycle systems, achieve their efficiency gains over rocket systems by getting their oxygen for combustion from the atmosphere, as opposed to a rocket that must carry its oxygen. Once a hypersonic vehicle has accelerated to more than twice the speed of sound, the turbine or rockets are turned off, and the engine relies solely on oxygen in the atmosphere to burn fuel. When the vehicle has accelerated to more than 10 to 15 times the speed of sound, the engine converts to a conventional rocket-powered system to propel the craft into orbit or sustain it to suborbital flight speed. NASA's series of hypersonic flight demonstrators includes three air-breathing vehicles: the X-43A, X-43B and X-43C.

The gravitational field surrounding this massive cluster of galaxies, Abell 68, acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies. Like a fun house mirror, lensing creates a fantasy landscape of arc-like images and mirror images of background galaxies. The foreground cluster is 2 billion light-years away, and the lensed images come from galaxies far behind it. In this photo, the image of a spiral galaxy at upper left has been stretched and mirrored into a shape similar to that of a simulated alien from the classic 1970s computer game "Space Invaders!" A second, less distorted image of the same galaxy appears to the left of the large, bright elliptical galaxy. In the upper right of the photo is another striking feature of the image that is unrelated to gravitational lensing. What appears to be purple liquid dripping from a galaxy is a phenomenon called ram-pressure stripping. The gas clouds within the galaxy are being stripped out and heated up as the galaxy passes through a region of denser intergalactic gas. This image was taken in infrared light by Hubble’s Wide Field Camera 3, and combined with near-infrared observations from Hubble’s Advanced Camera for Surveys. The image is based in part on data spotted by Nick Rose in the Hubble’s Hidden Treasures image processing competition.
