NASA’s Orion Spacecraft Engineers begin Summer with Safety System Tests

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Engineers working on NASA’s Orion kicked off summer with a series of important tests for some of the spacecraft’s critical safety systems. In the Utah desert, the skies over Arizona and the water at Johnson Space Center in Houston, the team is making sure Orion is safe from launch to splashdown.

At the Promontory, Utah, facility of Orion subcontractor Orbital ATK, engineers tested the abort motor for Orion’s launch abort system June 15th, firing the 17-foot tall motor for five seconds. The motor was fastened to a vertical test stand with its nozzles pointed toward the sky for the test. It produced enough thrust to lift 66 large SUVs off the ground and helps qualify the system for future missions with astronauts.

NASA’s Mars Exploration Rover Opportunity passes Crater that’s reminder of Apollo 16 mission

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Mars Exploration Rover Opportunity passed near a young crater this spring during the 45th anniversary of Apollo 16’s trip to Earth’s moon, prompting a connection between two missions.

Opportunity’s science team informally named the Martian feature “Orion Crater.” The name honors the Apollo 16 lunar module, Orion, which carried astronauts John Young and Charles Duke to and from the surface of the moon in April 1972 while crewmate Ken Mattingly piloted the Apollo 16 command module, Casper, in orbit around the moon. Orion is also the name of NASA’s new spacecraft that will carry humans into deep space and sustain them during travel beyond Earth orbit.

NASA reports Short Spacewalk Complete After Successful Installation Work

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA concluded their spacewalk at the International Space Station at 9:06pm CDT. During the spacewalk, which lasted two hours and 46 minutes, the two astronauts successfully replaced a computer relay box, and installed a pair of antennas on station to enhance wireless communication for future spacewalks.

Spacewalkers have now spent a total of 1,250 hours and 41 minutes working outside the station during 201 spacewalks in support of assembly and maintenance of the orbiting laboratory.

NASA looks at the Super Bowl – 5 Things Football has in Common with Space

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As Super Bowl LI in Houston Texas approaches and players, coaches and a host of personnel behind the scenes prepare for the big game in Space City, NASA remains on the cutting edge of human space exploration, setting its sights on the journey to Mars.

A football player’s journey to the end zone, though, has a lot more in common to space exploration than one might think.

Here are five similarities.

NASA Astronauts complete Second Spacewalk of the year on International Space Station

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Expedition 50 Commander Shane Kimbrough and Flight Engineer Thomas Pesquet concluded their spacewalk at 12:20pm EST. During the nearly six hour spacewalk, the two NASA astronauts successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station.

The new lithium-ion batteries and adapter plates replace the nickel-hydrogen batteries currently used on the station to store electrical energy generated by the station’s solar arrays.

NASA to test Space Launch System’s Largest Fuel Tank

 

Written by Tracy McMahan
NASA’s Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Major construction is complete on NASA’s largest new Space Launch System structural test stand, and engineers are now installing equipment needed to test the rocket’s biggest fuel tank.

The stand is critical for ensuring SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent on its first flight, and later on the second flight, which will carry up to four astronauts in the Orion spacecraft on a journey around the moon, into the deep-space proving ground for the technology needed for the journey to Mars.

NASA advances Exploration Objectives in 2016

 

Written by Bob Jacobs / Allard Beutel
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.

“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”

NASA’s Orion Spacecraft to make leaps forward in 2017

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – From the beginning of assembly work on the Orion crew module at NASA’s Kennedy Space Center in Florida to testing a range of the spacecraft systems, engineers made headway in 2016 in advance of the spacecraft’s 2018 mission beyond the moon.

A look at the important milestones that lie ahead in the next year give a glimpse into how NASA is pressing ahead to develop, build, test and fly the spacecraft that will enable human missions far into deep space.

NASA’s Journey to Mars builds ground work for missions beyond our Solar System

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Humanity’s great leap into the space between the stars has, in a sense, already begun. NASA’s Voyager 1 probe broke through the sun’s magnetic bubble to touch the interstellar wind. Voyager 2 isn’t far behind. New Horizons shot past Pluto on its way to encounters with more distant dwarf worlds, the rubble at the solar system’s edge.

Closer to home, we’re working on techniques to help us cross greater distances. Astronauts feast on romaine lettuce grown aboard the International Space Station, perhaps a preview of future banquets en route to Mars, or to deep space.

NASA Scientists develop Food Bars for Orion Spacecraft Astronauts

 

NASA Headquarters

NASA - National Aeronautics and Space Administration

Washington, D.C. – When astronauts in the Orion spacecraft travel beyond the moon to explore deep space destinations, they’ll need a robust diet to keep them healthy and sharp.

While crew members aboard the International Space Station can choose from approximately 200 items for their meals and have the space to stow an array of options, feeding the crew on deep space missions presents several unique challenges that NASA scientists are working to tackle.
