The launch abort motor for Orion’s launch abort system (LAS) for Artemis II, enclosed in its shipping container, arrives at NASA’s Kennedy Space Center in Florida on April 13, 2020. The motor arrived from Northrop Grumman in Promontory, Utah, and was transported to the Launch Abort System Facility where it will undergo testing in preparation for the second Artemis mission. The launch abort motor is one of three motors on the LAS. The LAS will be positioned atop the Orion crew module and is designed to protect astronauts if a problem arises during launch by pulling the spacecraft away from a failing rocket. Artemis II will take the first humans in orbit around the Moon in the 21st century.

Secured on a flatbed transporter in its shipping container, the ground test motor for Orion's Launch Abort System (LAS) is moved to the Rotation, Processing and Surge Facility (RPSF) on July 20, 2018, at NASA's Kennedy Space Center in Florida. In the RPSF the motor will be inspected and prepared for transport to Space Launch Complex 46 (SLC-46) at Cape Canaveral Air Force Station for mechanical fit testing. This inert motor will not be used for flight, but will be used to certify flight hardware assembly in preparation for a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019. During the test, the booster will launch from SLC 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. NASA's Orion and Exploration Ground Systems programs and their contractors from Jacob's and Northrup Grumman in conjunction with the Air Force Space and Missile Center's Launch Operations branch SMC/LEXO, are performing the pathfinding exercises and flight operations for AA-2.

The LAS is designed to pull the Orion capsule and its crew away to safety if an emergency occurs during ascent of the Space Launch System (SLS) rocket. During Artemis 1, the uncrewed Orion spacecraft will launch atop the SLS from Launch Pad 39B at Kennedy. Orion will embark on an approximately three-week mission that will take the spacecraft thousands of miles past the Moon. Orion will return to Earth and splashdown in the Pacific Ocean off the coast of California, where it will be retrieved and returned to Kennedy.

In the transfer aisle inside the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida, a crane is used to lift up a shipping container with the ground test motor for Orion's Launch Abort System (LAS) inside on July 20, 2018. The container will be lifted and transferred to another transporter and moved to the Rotation, Processing and Surge Facility where it will be inspected and prepared for transport to Space Launch Complex 46 (SLC-46) at Cape Canaveral Air Force Station for mechanical fit testing. This inert motor will not be used for flight, but will be used to certify flight hardware assembly in preparation for a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019. During the test, the booster will launch from SLC 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. NASA's Orion and Exploration Ground Systems programs and their contractors from Jacob's and Northrup Grumman in conjunction with the Air Force Space and Missile Center's Launch Operations branch SMC/LEXO, are performing the pathfinding exercises and flight operations for AA-2.

ISS014-E-13598 (29 Jan. 2007) --- Montevideo, Uruguay is featured in this image photographed by an Expedition 14 crewmember on the International Space Station. Reflective roofing materials and dark asphalt streets outline the urban grid pattern of Uruguay's capital city of Montevideo in this image. The city may be viewed as a precursor of the predicted global population shift from dominantly rural to urban environments (by 2030, according to recent United Nations estimates) -- nearly half of Uruguay's total population now lives in the Montevideo metropolitan area. Located on the southern coastline of Uruguay along the Rio de la Plata, Montevideo Bay provides an important harbor and port facilities for transport of South American agricultural products. This view is of sufficient resolution (approximately 7 meters/pixel) to discriminate between dark green canopied tree cover and light green grass - important information for study of urban ecology and climate, as well as city water use planning - in a large golf course located at the southern edge of the city (near center right). Sediment plumes along the coastline to the southeast of the city are also visible; rough patterns in the water surface of Montevideo Bay and the Rio de la Plata are a combination of wind disturbance and sediments.

LAS VEGAS -- The Boeing Company tests the forward heat shield FHS jettison system of its CST-100 spacecraft at the Bigelow Aerospace facility in Las Vegas as part of an agreement with NASA's Commercial Crew Program CCP during Commercial Crew Development Round 2 CCDev2) activities. The FHS will protect the spacecraft's parachutes, rendezvous-and-docking sensor packages, and docking mechanism during ascent and re-entry. During a mission to low Earth orbit, the shield will be jettisoned after re-entry heating, allowing the spacecraft's air bags to deploy for a safe landing. In 2011, NASA selected Boeing for CCDev2 to mature the design and development of a crew transportation system with the overall goal of accelerating a United States-led capability to the International Space Station. The goal of CCP is to drive down the cost of space travel as well as open up space to more people than ever before by balancing industry’s own innovative capabilities with NASA's 50 years of human spaceflight experience. Six other aerospace companies also were selected to mature launch vehicle and spacecraft designs under CCDev2, including Alliant Techsystems Inc. ATK, Excalibur Almaz Inc., Blue Origin, Sierra Nevada Corp. SNC, Space Exploration Technologies SpaceX, and United Launch Alliance ULA. For more information, visit www.nasa.gov/commercialcrew.

LAS CRUCES, N.M. -- Pratt & Whitney Rocketdyne tests a thruster destined for Boeing's CST-100 spacecraft. The thruster was fired in a vacuum chamber that simulated a space-like environment of 100,000 feet at NASA's White Sands Test Facility in Las Cruces, N.M., to verify its durability in extreme heat, evaluate the opening and closing of its valves and confirm continuous combustion and performance. Twenty-four thrusters will be part of the spacecraft's orbital maneuvering and attitude control system OMAC, giving the CST-100 the ability to maneuver in space and during re-entry. The thrusters also will allow the spacecraft to separate from its launch vehicle if an abort becomes necessary during launch or ascent.

This radar image of the Shangri-La Sand Sea on Titan from NASA's Cassini spacecraft shows hundreds of sand dunes are visible as dark lines snaking across the surface. These dunes display patterns of undulation and divergence around elevated mountains (which appear bright to the radar), thereby showing the direction of wind and sand transport on the surface. Sands being carried from left to right (west to east) cannot surmount the tallest obstacles; instead, they are directed through chutes and canyons between the tall features, evident in thin, blade-like, isolated dunes between bright some features. Once sands have passed around the obstacles, they resume their downwind course, at first collecting into small, patchy dunes and then organizing into larger, more pervasive linear forms, before being halted once again by obstacles. These patterns reveal the effects not only of wind -- perhaps even modern winds if the dunes are actively moving today -- but also the effects of underlying bedrock and surrounding topography. Dunes across the solar system aid in our understanding of underlying topography, winds and climate, past and present. Similar patterns can be seen in dunes of the Great Sandy Desert in Australia, where dunes undulate broadly across the uneven terrain and are halted at the margins of sand-trapping lakes. The dune orientations correlate generally with the direction of current trade winds, and reveal that winds must have been similar back when the dunes formed, during the Pleistocene glacial and interglacial periods. The image was taken by the Cassini Synthetic Aperture radar (SAR) on July 25, 2016 during the mission's 122nd targeted Titan encounter. The image has been modified by the denoising method described in A. Lucas, JGR:Planets (2014). http://photojournal.jpl.nasa.gov/catalog/PIA20711
