3D Printers to Build NASA's Spare Parts & Rocket Engines
Charles Bolden, NASA administrator and former astronaut, praises the potential of 3D printing to one day quickly create any parts that space travelers would need, and do it with material from whatever planet, moon, or asteroid they happen to inhabit.
In his recent State of the Union address,
President Obama spoke glowingly of 3D printing, saying the technology "has the potential to revolutionize the way we make almost everything." At NASA, the revolution is already under way. Engineers are now testing 3D printing (more broadly known as additive manufacturing) for making engine parts for the Space Launch System (SLS), the vehicle slated to take mankind back to the moon, to asteroids, and someday to Mars. A 3D printer will soon head to the International Space Station. And in the future, NASA hopes 3D printers will let astronauts fabricate tools, spare parts, or virtually anything their mission requires throughout the solar system.
"Additive manufacturing is this new technology that really gives us an endless set of possibilities for the products we manufacture at NASA for our terrestrial launch vehicle and our in-space applications," says John Vickers, assistant manager of the Materials and Processes Laboratory at NASA's Marshall Space Flight Center. In a sign of how seriously NASA is taking the technology, on Friday agency chief Charles Bolden toured an additive manufacturing facility at Marshall. "The things going on here are very impressive," Bolden tells PM. "I was surprised by the maturity of the systems already."
In a statement issued Friday afternoon, FAA said US deputy transportation secretary John Porcari, FAA administrator Michael Huerta and other officials from FAA met with senior Boeing executives “to discuss the status of ongoing work to address 787 battery issues.”
FAA grounded the 787 on Jan. 16; 50 Dreamliners had been in service worldwide. The agency stated, “The FAA is reviewing a Boeing proposal and will analyze it closely. The safety of the flying public is our top priority and we won’t allow the 787 to return to commercial service until we’re confident that any proposed solution has addressed the battery failure risks.”

Boeing Says Efficiencies On The Factory Floors Will Allow Hiring To Slow
Boeing says it plans to increase airliner production as airlines place major orders to replace older jets, but that efficiencies on its factory floors will allow it to slow the pace of hiring replacement workers.
In an interview with Dow Jones Newswires, Boeing VP for Marketing Randy Tinseth said that airline passenger growth is expected to continue to grow by about 5 percent this year, after a 6% jump last year, even with the global economic recovery continuing as a sluggish pace. Tinseth described the backlog of orders for new airliners as a "challenge"
But the Puget Sound Business Journal reports that Boeing's workforce will peak at about 83,000 this year, and then the pace of hiring will slow. The company will continue to replace retiring workers, but at a reduced pace from previous years. READ MORE: AINOnline
SpaceX founder Elon Musk (shown below, with friends, in Zero-G) announced April 1st that a consortium of commercial space companies have closed a deal with the federal government for the outright purchase of NASA.
The consortium is led by SpaceX and ULA, which both have operational boosters that are nearly ready to begin carrying humans into orbit. "The Obama administration was thrilled to be shed of the agency, which it saw as nothing more than a cost center," Musk said. "Between the ULA Atlas boosters which are very reliable, and with Falcon 9 nearly ready to begin operations, we just saw this as the right deal at the right time. In very short order, commercial space will be the only space."
Other consortium members include Virgin Galactic, which will become the suborbital research arm of the new CASA ... the Commercial Aeronautics and Space Association. Sierra Nevada Corp and XCOR will be combining their talents to produce the NextGen Space Shuttle to ferry astronauts back and forth between the ISS. "Relying on Russia to carry astronauts to ISS using 40-year-old Soyuz technology is just unacceptable," said Sierra Nevada Corp. CEO Faith Ozeman. "We know we can get people to ISS more efficiently, and since we now own the company, we know that we can accelerate the process of getting human-rated spacecraft flying in very short order. We expect to be flying to ISS in just a couple of years.

Autonomous Quadrotors Fly Amazing Formations
Roboticists at the University of Pennsylvania’s GRASP are able to get as many as 20 of their autonomous microcopters to fly in formation and perform complex maneuvers flawlessly.
In an impressive new video, the GRASP — General Robotics, Automation, Sensing and Perception — team makes their swarm of flying microbots flip, change direction, navigate through obstacles and even fly figure-eights with jaw-dropping agility and precision.
Pilots Of Single-Place And Experimental Jets Given A Reprieve From Proficiency Check Requirements

Pilots Of Single-Place And Experimental Jets Given A Reprieve From Proficiency Check Requirements
The FAA has listened to those commenting on its proposed changes to FAR Section 61.85 and has proposed an amendment to the new rule pushing back the implementation of proficiency check requirements for pilots of single-place and experimental turbojets for a year.
In a final rule published on August 31, 2011 (76 FR 54095). In that rule, the FAA amended its regulations to revise the pilot, flight instructor, and pilot school certification requirements. In particular, the FAA expanded the obligation for a pilot-in-command (PIC) proficiency check to pilots of all turbojet-powered aircraft. This expansion included single-pilot turbojet-powered aircraft and, with some exceptions, also included turbojet-powered experimental aircraft. The FAA intended, and those that commented on the proposed rule expected, a period that would allow pilots of these aircraft sufficient time to come into compliance with the new PIC requirement.
As part of the final rule, the FAA revised Sec. 61.58 to extend the requirements for PIC proficiency checks. Prior to the final rule, this section only required PIC proficiency checks for pilots acting as PIC in aircraft that were type certificated for more than one pilot flight crewmember. In the Notice of Proposed Rulemaking (NPRM) published on August 31, 2009 (74 FR 44779), the FAA proposed to extend the Sec. 61.58 PIC proficiency check requirements to pilots acting as PIC of any turbojet powered aircraft. The FAA received a significant amount of comments opposing the proposed rule as written due to the impact it would have on pilots operating experimental jets. Based on the comments, the FAA intentionally included the Sec. 61.58 PIC proficiency check requirements for pilots operating experimental turbojet-powered aircraft. However, pilots operating experimental aircraft that possessed only one seat through original design or through modification were excepted from these requirements, and pilots of other experimental turbo-jet powered aircraft were given several alternative means of compliance with the Sec. 61.58 proficiency check requirements.
