NASA partners Boeing and SpaceX complete latest round of Parachute TestsWritten by Marie Lewis
On March 4th, SpaceX performed its 14th overall parachute test supporting Crew Dragon development. This exercise was the first of several planned parachute system qualification tests ahead of the spacecraft’s first crewed flight and resulted in the successful touchdown of Crew Dragon’s parachute system. ![]() At left, Boeing conducted the first in a series of parachute reliability tests its Starliner flight drogue and main parachute system Feb. 22, 2018, over Yuma Arizona. (NASA) At right, SpaceX performed its fourteenth overall parachute test supporting Crew Dragon development March 4, 2018, over the Mojave Desert in Southern California. The test demonstrated an off-nominal, or abnormal, situation, deploying only one of the two drogue chutes and three of the four main parachutes.

NASA Engineers successfully use 3-D Printed Part on RS-25 Rocket EngineNASA Headquarters
During flight, a rocket may experience powerful up-and-down vibrations mainly due to the engines and propellant in the feed lines. This is called the pogo effect and is similar to the up-and-down motion of bouncing on a pogo stick. The 3-D printed part tested, called the pogo accumulator, is a beachball-sized piece of hardware that acts as a shock absorber by regulating liquid oxygen movement in the engine to prevent the vibrations that can destabilize a rocket’s flight. ![]() The successful hot-fire test of an RS-25 development engine at NASA’s Stennis Space Center on Dec. 13 included NASA’s largest 3-D printed rocket engine component to date, the pogo accumulator assembly. The test was the first of 50 for NASA’s restart of RS-25 engine production. (NASA/Stennis) «Read the rest of this article» Sections: Technology | No Comments
NASA to do feasibility study on manning Orion Spacecraft’s first flightWritten by Cheryl Warner
Acting Administrator Robert Lightfoot announced February 15th that he had asked William Gerstenmaier, associate administrator for NASA’s Human Exploration and Operations Mission Directorate in Washington, to conduct the study, and it is now underway. NASA expects it to be completed in early spring. ![]() NASA Continues Progress to Send Humans to Deep Space. Pictured is NASA’s Space Launch System (SLS) rocket.

NASA to test Space Launch System’s Largest Fuel TankWritten by Tracy McMahan
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. ![]() Robert Bobo, left, and Mike Nichols talk beneath the 221-foot-tall Test Stand 4693, the largest of two new Space Launch System test stands at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Bobo manages SLS structural strength testing, and Nichols is lead test engineer for the SLS liquid hydrogen tank, which the stand will subject to the forces it must endure during launch and flight.

NASA says Machines of the future will Self Diagnosis themselvesNASA Headquarters
“There’s going to be an integrated system-health engine as part of every system out there, and it will be able to interface with other systems and components,” says Cirulli. “That’s what’s missing today.” He compares the capability to how sick human patients can verbalize symptoms to a doctor, giving them the crucial information they need to diagnose a problem. ![]() The IMS that CEMSol licensed from Ames Research Center to develop its ISHM software has also been applied to the Black Hawk helicopter engine.

NASA prepares Orion spacecraft and Space Launch System rocket for first test flightNASA Headquarters
Orion’s first flight atop the SLS will not have humans aboard, but it paves the way for future missions with astronauts. Ultimately, it will help NASA prepare for missions to the Red Planet. During this flight, currently designated Exploration Mission-1 (EM-1), the spacecraft will travel thousands of miles beyond the moon over the course of about a three-week mission. ![]() NASA¹s Space Launch System rocket will launch with Orion atop it from Launch Complex 39B at NASA¹s modernized spaceport at Kennedy Space Center in Florida.

NASA’s Mars Reconnaissance Orbiter discovers large new Crater on MarsWritten by Guy Webster
The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in the Martian sky caused by intense friction between an incoming asteroid and the planet’s atmosphere. ![]() This is the largest fresh impact crater anywhere ever clearly confirmed from before-and-after images. It is 159 feet across. (NASA/JPL-Caltech/Univ. of Arizona) «Read the rest of this article» Sections: Technology | No Comments
NASA Astronauts Test Tools Underwater for Asteroid MissionNASA’s Johnson Space Center
Stan Love and Steve Bowen have between them spent more than 62 hours in the vacuum of space on nine shuttle mission spacewalks, and they’re putting that experience to use here on Earth by helping engineers determine what astronauts will need on NASA’s next step toward Deep Space. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Curiosity Mars rover captures first ever photo of Asteroids from the surface of MarsWritten by Guy Webster
These two — the largest and third-largest bodies in the asteroid belt between Mars and Jupiter — are the destinations of NASA’s Dawn mission. Dawn orbited Vesta in 2011 and 2012, and is on its way to begin orbiting Ceres next year. Ceres is a dwarf planet, as well as an asteroid. ![]() NASA’s Curiosity Mars rover has caught the first image of asteroids taken from the surface of Mars. The image includes two asteroids, Ceres and Vesta. This version includes Mars’ moon Deimos in a circular, exposure-adjusted inset and square insets at left from other observations the same night. «Read the rest of this article» Sections: Technology | No Comments
