NASA’s MMS Spacecraft Launches on an Atlas V Rocket


The United Launch Alliance Atlas V rocket with NASA’s Magnetospheric Multiscale (MMS) spacecraft onboard launches from the Cape Canaveral Air Force Station Space Launch Complex 41, Thursday, March 12, 2015, Florida. NASA’s MMS mission studies the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.

Expedition 42 Soyuz Landing


The Soyuz TMA-14M spacecraft is seen as it lands with Expedition 42 commander Barry Wilmore of NASA, Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos) and Elena Serova of Roscosmos near the town of Dzhezkazgan, Kazakhstan on Wednesday, March 11, 2015 (Thursday, March 12, Kazakh time). NASA astronaut Wilmore, Russian cosmonauts Samokutyaev and Serova returned to Earth after almost six months onboard the International Space Station where they served as members of the Expedition 41 and 42 crews. The spacecraft touched down safely at approximately 10:07 p.m. EDT.

Expedition 42 Returns to Earth


The Soyuz TMA-14M spacecraft is seen as it lands with International Space Station Expedition 42 commander Barry Wilmore of NASA, Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos) and Elena Serova of Roscosmos near the town of Zhezkazgan, Kazakhstan. The landing took place on the evening of Wednesday, March 11 in the U.S, and early in the morning on Thursday, March 12, in Kazakhstan.

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 largest, most powerful rocket booster ever built successfully fired up Wednesday for a major-milestone ground test in preparation for future missions to help propel NASA’s Space Launch System (SLS) rocket and Orion spacecraft to deep space destinations, including an asteroid and Mars.

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


Engineers at Orbital ATK prepare to test the largest, most powerful booster ever built for NASA’s new rocket, the Space Launch System (SLS), which will fire up for a ground test at 11:30 a.m. EDT on Wednesday, March 11, at Orbital ATK Propulsion Systems’ test facilities in Promontory, Utah.

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


Engineers across the country have been busy taking a closer look at NASA’s Orion spacecraft and the data it produced during its successful flight test in December 2014. Inside the Launch Abort System Facility at NASA’s Kennedy Space Center in Florida, Orion was lifted using a special crane for removal of its heat shield on Feb. 13, 2015. In the background, technicians move the heat shield on a work stand. The spacecraft’s heat shield protected Orion as it reentered Earth’s atmosphere at searing temperatures. Removing the back shell allows the team to get a closer look at Orion’s systems to see how they fared during the trip to space. The heat shield was removed in preparation for shipment to NASA’s Marshall Space Flight Center in Huntsville, Alabama, where special equipment will be used to remove its ablative material. From there, the heat shield will be shipped to NASA’s Langley Research Center in Hampton, Virginia, where it will be outfitted on a test article for water impact testing.

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.

Charter School in Miami Fails, but Proves Useful on Jeb Bush’s Résumé by JASON HOROWITZ



By JASON HOROWITZ


The Liberty City Charter School, the first of its kind in Florida and a pioneer in what became a national movement, is now defunct.
