Expedition 42 Returns to Earth
The three crew members returned to Earth after a 167-day mission on the orbital outpost that included hundreds of scientific experiments and several spacewalks to prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft.

Test Firing of Booster for NASA’s New Rocket
The booster fired for two minutes, the same amount of time it will fire when it lifts the SLS off the launch pad, and produced about 3.6 million pounds of thrust. The test was conducted at the Promontory, Utah test facility of commercial partner Orbital ATK, and is one of two tests planned to qualify the booster for flight. Once qualified, the flight booster hardware will be ready for shipment to NASA’s Kennedy Space Center in Florida for the first SLS flight.

Preparing to Test the Booster for NASA’s New Rocket
The two-minute static test is a significant milestone for the SLS as part of NASA’s journey to Mars, and follows years of development. It is one of two ground tests to qualify the booster for flight. A second test is planned for early 2016. Once qualification is complete, the hardware will be ready to help send the rocket, along with NASA’s Orion spacecraft, on its first flight test. When completed, two five-segment, solid-rocket boosters and four RS-25 main engines will power the SLS as it begins its deep space missions. The boosters operate in parallel with the main engines for the first two minutes of flight, providing more than 75 percent of the thrust needed for the rocket to escape Earth’s gravitational pull.
The first flight test of the SLS will feature a configuration for a 70-metric-ton (77-ton) lift capacity and carry an uncrewed Orion spacecraft beyond low-Earth orbit to test the performance of the integrated system. As the SLS is updated, it will provide an unprecedented lift capability of 130 metric tons (143 tons) to enable missions even farther into our solar system.
Live coverage of the test on NASA TV begins on Wednesday at 11:00 a.m. EDT.

Taking a Closer Look at Orion After Successful Flight Test
Meanwhile, NASA and Lockheed Martin, the prime contractor for Orion, continue to take a look at the data the flight test produced to validate pre-flight models and improve the spacecraft’s design. Analysis of data obtained during its two-orbit, four-and-a-half hour mission Dec. 5 will provide engineers detailed information on how the spacecraft fared.

Ceres Seen From NASA’s Dawn Spacecraft
This image of Ceres was taken by the Dawn spacecraft on March 1, just a few days before the mission achieved orbit around the previously unexplored world. The image shows Ceres as a crescent, mostly in shadow because the spacecraft’s trajectory put it on a side of Ceres that faces away from the sun until mid-April. When Dawn emerges from Ceres’ dark side, it will deliver ever-sharper images as it spirals to lower orbits around the planet.
The image was obtained at a distance of about 30,000 miles (about 48,000 kilometers) at a sun-Ceres-spacecraft angle, or phase angle, of 123 degrees. Image scale on Ceres is 1.9 miles (2.9 kilometers) per pixel. Ceres has an average diameter of about 590 miles (950 kilometers).
Dawn’s mission is managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, for NASA’s Science Mission Directorate in Washington. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. The University of California, Los Angeles, is responsible for overall Dawn mission science. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.

Astronaut Scott Kelly Preparing for Launch on One-Year Mission
Island of Hawaii From the International Space Station
Crewmembers on the space station photograph the Earth from their unique point of view located 200 miles above the surface as part of the Crew Earth Observations program. Photographs record how the planet is changing over time, from human-caused changes like urban growth and reservoir construction, to natural dynamic events such as hurricanes, floods and volcanic eruptions. Astronauts have used hand-held cameras to photograph the Earth for more than 40 years, beginning with the Mercury missions in the early 1960s. The ISS maintains an altitude between 220 – 286 miles (354 – 460 km) above the Earth, and an orbital inclination of 51.6˚, providing an excellent stage for observing most populated areas of the world.

The NACA Spirit Captured, 1945
The NACA was the main institutional basis for creating NASA in 1958.
On March 3, 1915 – one hundred years ago — the U.S. Congress established the NACA in order “to supervise and direct the scientific study of the problems of flight with a view to their practical solution.”
From humble beginnings with a $5000 budget, no paid staff and no facilities, the NACA won the Collier trophy five times. Its researchers made critical contributions to victory in World War II, spawned a world-leading civil aviation manufacturing industry, propelled supersonic flight, supported national security during the Cold War, and laid the foundation for modern air travel and the space age.
