CAPE CANAVERAL, Fla. -- In high bay 4 of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane is attached to segment 5 of the Ares I-X upper stage simulator segments to lift it. Segment 5 will be stacked on to segment 4, at the top of the tall stack at right.The upper stage simulator comprises 11 segments, each approximately 18 feet in diameter, that will be used in the test flight known as Ares I-X in 2009. The simulator segments will simulate the mass and the outer mold line. The upper stage accounts for nearly one-quarter of the total height of the Ares I. It will take the Ares I on the second phase of its journey from Earth, providing the guidance, navigation and control needed for the second phase of the Ares I ascent flight.

CAPE CANAVERAL, Fla. – In the Vehicle Assembly Building's High Bay 4, assembly of the Ares I-X rocket nears completion. The yellow framework, nicknamed the "birdcage," is lowered by crane toward Super Stack 5. The birdcage has the ability to lift and to stack and de-stack the Ares I-X rocket's Super Stack 5. Next, the stack will be lifted on top of the segments already in place on the mobile launcher platform, completing assembly of the rocket. Five super stacks make up the rocket's upper stage that will be integrated with the four-segment solid rocket booster first stage. Ares I-X is the test vehicle for the Ares I, which is part of the Constellation Program to return men to the moon and beyond. The Ares I-X flight test is targeted for Oct. 31, pending formal NASA Headquarters approval. Photo credit: NASA/Jack Pfaller

CAPE CANAVERAL, Fla. – The yellow framework seen here is the lifting fixture nicknamed the "Birdcage" that will have the ability to lift the Crew Module, or CM, and Launch Abort System, or LAS, assembly for the Ares I-X rocket and to stack and de-stack the assembly from the Service Module/Spacecraft Adapter assembly. It will also have the ability to lift and to stack and de-stack Stack-5 (all of the above components) from the Ares I-X in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Ares I-X is the test flight for the Ares I. The I-X flight will provide NASA an early opportunity to test and prove hardware, facilities and ground operations associated with Ares I. The launch of the 321-foot-tall, full-scale Ares I-X, targeted for July 2009, will be the first in a series of unpiloted rocket launches from Kennedy. When fully developed, the 16-foot diameter crew module will furnish living space and reentry protection for the astronauts, while their launch abort system will provide safe evacuation if a launch vehicle failure occurs.

It will also have the ability to lift and to stack and de-stack Stack-5 (all of the above components) from the Ares I-X in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Ares I-X is the test flight for the Ares I. The I-X flight will provide NASA an early opportunity to test and prove hardware, facilities and ground operations associated with Ares I. The launch of the 321-foot-tall, full-scale Ares I-X, targeted for July 2009, will be the first in a series of unpiloted rocket launches from Kennedy. When fully developed, the 16-foot diameter crew module will furnish living space and reentry protection for the astronauts, while their launch abort system will provide safe evacuation if a launch vehicle failure occurs.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of the main channel of Ares Vallis, as well as a small side tributary. Located in Margaritifer Terra, Ares Vallis is part of a large system of channels that arise in Valles Marineris and flow northward into Chryse Planitia.

Ben Feist, software engineer on the Extravehicular Activity Mission System Software (EMSS) team, uses the suite of software he and other members of the Astromaterials Research and Exploration Science (ARES) division at NASA's Johnson Space Center in Houston developed to plan and monitor spacewalks. The JETT 5 field test was the first time this software was fully integrated into a simulated mission, supporting both science and mission control operations. JETT 5 was a week-long field test conducted in the lunar-like landscape of the San Francisco Volcanic Field near Flagstaff, Arizona, with a team of flight controllers and scientists at Johnson monitoring and guiding the activities.

The sun emitted a significant solar flare, peaking at 5:40 p.m. EDT on Oct. 24, 2014. The flare erupted from a particularly large active region -- labeled AR 12192 -- on the sun that is the largest in 24 years. This is the fourth substantial flare from this active region since Oct. 19.

Today's VIS image is located in Aram Chaos. Aram Chaos was initially formed by a large impact. Over time the crater interior was modified by several different processes, including liquid water. Located near Ares Vallis, a narrow channel links the Aram Chaos crater with Ares Vallis indicating a substantial amount of water was located in the crater. Chaos forms from erosion of the surface into mesa features. With time the valleys expand creating the jumble of hills seen in the image. The THEMIS VIS camera contains 5 filters.

This false color image contains several channel features. Towards the top of the image are several stream-lined islands, created by liquid flow eroding preexisting rock. The islands have a tear-drop shape, with the pointy end down stream from the rounded end. In this case the fluid flowed from the bottom right of the frame towards the upper left. Just below the center of the image is a larger, deeper channel. All these channel features merge into Ares Vallis, a huge outflow channel that empties into Chryse Planitia.

Active region AR 12192 on the sun erupted with a strong flare on Oct. 24, 2014, as seen in the bright light of this image captured by NASA's Solar Dynamics Observatory. This image shows extreme ultraviolet light that highlights the hot solar material in the sun's atmosphere. Credit: NASA/GSFC/SDO More info: The sun emitted a significant solar flare, peaking at 5:40 p.m. EDT on Oct. 24, 2014. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an X3.1-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. The flare erupted from a particularly large active region -- labeled AR 12192 -- on the sun that is the largest in 24 years.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of Margaritifer Terra just east of Ares Vallis. If you look closely at the bottom of the image, you will see spots of purple and yellow, with similar 'shapes'. These features are not image artifacts. These are clouds. When this image was collected there were high altitude ice clouds being blown across the sky, moving fast enough to reach a different location between the time each filter was collected. Color VIS images are typically the only image type where ice clouds can be identified. The THEMIS VIS camera is capable of capturing color images of the Martian surface using five different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from using multiple filters. To make a color image, three of the five filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image. These three images are then combined to produce a full color, single image. Because the THEMIS color filters don't span the full range of colors seen by the human eye, a color THEMIS image does not represent true color. Also, because each single-filter image is contrast enhanced before inclusion in the three-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. Note that the long edges of THEMIS color images typically contain color artifacts that do not represent surface variation.
