Space Trucker

Posted by J VanDomelen

J VanDomelen SpaceX this month logged its fifth successful mission to the International Space Station (ISS) and had a hand in yet another historic first: delivering the first 3D printer in space. SpaceX launched its fifth journey to the ISS and fourth official Commercial Resupply (CRS) mission to the orbiting lab early this week, on Sunday, 21 September 2014 from Launch Complex 40 at Cape Canaveral Air Force Station, … Read More

John Day Shortly after I began to write about automotive electronics, a decade or so ago, I attended the SAE Convergence conference. I had been to many electronics industry events in the course of my career but this was my first in-depth exposure to chips, circuits and software for cars. The industry has changed dramatically between then and now and I’m looking forward to seeing the latest in Detroit (Cobo Center) … Read More

Testing, Testing, ISS

Posted by J VanDomelen

J VanDomelen Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have again logged an historic achievement. They have harnessed additive manufacturing (3D printing) to produce complex rocket engine parts faster and at a lower cost than with traditional manufacturing. NASA engineers worked with two different providers: Solid Concepts in Valencia, California, and Directed Manufacturing in Austin, … Read More

Additive Manufacturing at NASA

Posted by J VanDomelen

J VanDomelen The Aerojet Rocketdyne RS-25 engine powered NASA’s Space Shuttle and will power the upcoming Space Launch System (SLS). The SLS is a heavy-lift, exploration-class rocket currently under development to take humans beyond Earth orbit and Mars. NASA engineers recently produced the most complex rocket engine parts in the agency’s history using additive manufacturing, or 3D printing. Three-dimensional printers … Read More

J VanDomelen Late last month, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, completed testing the most complex rocket engine parts ever designed by the space agency and printed with additive manufacturing, or three-dimensional (3D) printing. The highly complex part NASA engineers designed is a rocket engine injector, which is responsible for sending propellant into the engine, and … Read More

Aren’t They All Alike?

Posted by John Day

John Day The past few weeks have been busy ones for Renesas Electronics, a major supplier of chips for automotive and other applications. The company introduced the R-Car V2H, its third-generation R-Car system-on-a-chip (SoC) and the first in the series optimized for advanced driver assistance systems (ADAS); 40 nm RH850/C1x microcontrollers (MCUs) for hybrid and electric vehicle motor control applications, … Read More

Whew!

Posted by John Day

John Day The Intelligent Transportation Society (ITS) World Congress in Detroit last week was quite an event, from Mary Barra’s keynote on Sunday evening, during which she announced GM’s entry into vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology, to Bill Ford’s Monday morning look at the future of transportation, to the myriad demos on Belle Isle, and the array of exhibits and panel sessions … Read More

John Day When Agero, best known for its roadside assistance services, introduced a smartphone-based telematics system for usage based insurance (UBI), I wondered about the benefit(s). Agero said its system offered advantages over OBDII hardware solutions for assessing behind-the-wheel behavior, but those advantages weren’t immediately obvious, so I asked Jeff Blecher, Agero’s senior VP of strategy, about them. He … Read More

Generation Gap

Posted by John Day

John Day This probably shouldn’t be a surprise, but it’s an observation supported by research: younger people are a lot more interested in automotive connectivity than older people are, and they are even more interested in mobile connectivity – smartphones and the like. Lochbridge, formerly the Professional Services Division of Compuware, surveyed consumers ranging in age from 18 to 65 to assess their opinions … Read More

Understanding the Satellite Situation

Posted by J VanDomelen

J VanDomelen On 22 Aug. 2014, Arianespace in France launched two satellites into orbit onboard a Russian Soyuz launch vehicle under contract with the European Space Agency (ESA) for its Galileo program. News that the launch vehicle failed to inject Galileo satellites 5 and 6 into the correct orbit rocked the military and aerospace (mil/aero) community this month. “Observations taken after the separation of … Read More

Inquiry into an Aerospace Anomaly

Posted by J VanDomelen

J VanDomelen Arianespace in France launched two satellites on the Russian Soyuz ST rocket. Telemetry data soon revealed that the spacecraft were placed in elliptical (rather than circular) orbit and in a lower orbit than anticipated; as a result, the satellites are operationally redundant, aerospace engineers indicate. Arianespace officials found that an anomaly occurred during “the flight phase involving the [Russian] … Read More

Billion-dollar Project Botched?

Posted by J VanDomelen

J VanDomelen Europe is in the process of assembling a civilian-operated satellite navigation system, designed to deliver greater precision than the U.S.’s Global Positioning System (GPS) satellite constellation, to the tune of 5.4 billion Euro. The full project calls for 30 modern satellites to be positioned precisely into orbit over the next few years. This week, however, the European Space Agency (ESA) hit a snag … Read More

J VanDomelen European Space Agency (ESA) officials in Paris reported this week an error—specifically, an orbital injection anomaly—in the launch of its two latest satellites under the Galileo program. Galileo, Europe’s global navigation satellite system, is intended to provide accurate, guaranteed global positioning that is under civilian control. It is interoperable with the United States’ Global Positioning System … Read More

The Rapidly Reusable Dragon

Posted by J VanDomelen

J VanDomelen SpaceX has been making a big splash recently with the release of the revolutionary Dragon Version 2. Never before has this military and aerospace (mil/aero) geek seen such a futuristic design that is fully functional. The new Dragon v2 is a major leap forward in manned spaceflight. It features many new, advanced, and life-saving features that this geek will highlight as we explore the Dragon v2 in this … Read More
