U.S citizens tend to think of NASA when the topic turns to space exploration But the European Space Agency (ESA), established in 1975 to combine the efforts of 19 European nations, has its own ideas for advancing space technology Among the most interesting efforts with which ESA is involved is one aimed at extending Internet connections to spacecraft Though its annual budget is about $5.2 billion compared to NASAs $18 billion, ESA is making important strides in fundamental space research FEATURES 54 Nanosats to test software From Engineer to Rocketman A trained mechanical engineer who seriously dabbled in rocketry as a hobbyist builds a rocket that climbs toover 100,000 ft Engineers and technicians at ESA today control satellites and space experiments using Packet Utilisation Standards, a software suite that dates to 1994 There have been upgrades since then, but the stumbling block to moving to newer software is that space scientists and the organizations that fund them must ensure the software, including operating systems, languages, and interfaces, is fit for space No one wants to use new and possibly problematic software on a multimillion-euro mission in space, says Mario Merri, head of the Mission Data Systems Div at ESA operations center Unfortunately, the only real way to prove software is fit is to take it into space and run it through its paces To lower the cost of validating software, and to ensure no missions are endangered, ESA researchers developed Operations Satellites, dubbed Op-Sats The 30 ì 10 ì 10-cm satellites mission is to test and validate critical onboard and ground software The spacecraft is outfitted with off-the-shelf processors that have more computing power than a satellite usually carries It is also designed to recover easily and quickly from buggy software Researchers on Earth can replace the entire onboard software suite with new and fresh code daily, letting developers troubleshoot their work in a real but safe environment The first Op-Sats could launch next year Spinning an interplanetary Web People increasingly take reliable and fast Internet access for granted Now space scientists want to extend the same simplicity and reliability of the Web to astronauts on the Moon or Mars The first goal will be to let astronauts communicate among themsleves, with control centers on 20 MACHINE DESIGN.com Op-Sats, here shown in an artists conception, are simple spacecraft designed solely to test software They will have a volume of about three liters but will carry offthe-shelf components such as three-axis attitude control systems, deployable fixed solar arrays, GPS receivers, and UHF communication systems It will also have state-of-the-art components such as S-band communications with an uplink rate four times greater than any other ESA spacecraft and a miniaturized X-band transcmitter providing up to 50 Mbps downlink These rates are up to several hundreds times better than any other satellite flown before Earth, and with space ships and bases But who knows; someday top level Internet domains may include such names as moon, mars, or sstation To this end, ESA, NASA, and other major space organizations and industrial partners have been working together as part of the Consultative Committee for Space Data Systems They have developed standards for hardware and data exchange that should pay off even in the short term for commercial space-flight businesses, satellite manufacturers, and space agencies Satellites have already been used for links between Earth and mission spacecraft In 2008, for example, ESAs Mars Express acted as a data-relay node between NASA technicians on Earth and their Phoenix Lander during decent and landing on Mars, It will repeat that task in August this year with NASAs Mars Science Laboratory And last December, ESAs worldwide tracking station network handled contact between Russian controllers and that countrys Phobos-Grunt mission to Mars Then, in October of this year, an astronaut on the International Space Station will practice at remotely controlling a planetary rover at ESAs operations center, simulating orbiterrover communication links on a planet like Mars Establishing technical standards and communication architectures isnt the most high-profile part of space exploration, but its absolutely vital for ensuring that the more-exciting efforts, like sending an astronaut to Mars, will work when that time comes, says Nestor Peccia, the JUNE 14, 2012 Made in America? 76 Hydraulic controls transform press technology Unlike traditional constant-speed hydraulics, variable-speed pump drives supply only the power a processrequires pressure data to the researchers through the entire crash event The original ESA engineer worked to convert the foil into a strip of about 50 individual sensors, each about a square centimeter At the end of each strip is a flexible printed-circuit board with a 50-channel amplifier When it is attached to a fender or bumper, it lets test engineers know how fast that metal is bending, as well as whether it is bending 20 in one direction or 60 in the other VW has now used the sensor in several crash tests and it has contributed to changes that make the cars safer, according to VW managers person responsible for ground software development at ESAs German operations center Tech transfer for piezo foil Back in the early 1990s, a German engineer was developing a new type of pressure sensor that would coat the wings of Hermes, a reusable mannedshuttle that would be launched into space The pressure senor used in VW crash tests is based on pressuresensitive piezo film and consists of 50 individual sensors, each atop an Ariane rocket sq cm, and a 50-channel amplifier, all flexibly printed on a thin and then return to and bendable circuit board Earth on it own, much like the Space Shuttle The sensor had to be light and thin so it would not add bulk or drag to the airfoil The engiA Swarm heads for space neer turned to piezoelectric foil to the job Like other Three identical Swarm satellites will launch from Russias Plesetsk Cosmodrome next month on a four-year mispiezo materials, the thin foil (30-microns thick) converts sion to explore the Earths magnetic field This is the first vibrations and pressures into electrical pulses that can be measured and interpreted continued on page 22 The foil senors were successfully tested in a hypersonic wind tunnel, but the Hermes project was cancelled So over the years, ESA has been looking for civilian uses Piezo material for the piezo sensors One of the earlier applications was suspended in a converting the foil to paint and putting it on a human mopaint was applied lar Scientists used this instrumented tooth to measure to a human molar forces a toothbrush puts on teeth to let scientists But just recently, Volkswagen saw the sensor demonmeasure the strated at the Hannover Fair at a booth set up by ESAs force of a toothbrush on a Technology Transfer Programme Office They quickly detooth cided to use the piezo sensors on crash-test vehicles Traditional sensors well at recording pressure up to the point of impact, then they are too often destroyed in the crash The foil versions, however, survive the crash, sending Leland Teschler Editor Resources: Intel, www.intel.com Semicon West and Intersolar 2012, http:// semiconwest.org/ Most light-emitting diodes are made in Asia, but future generations of LED manufacturing equipment could still be marked Made in the U S A. Though the 300-mm wafer has become the industry standard, chipmakers are transitioning to 450-mm versions, like this example at Innolas Semiconductor GmbH, a maker of wafer-sorting and laser-marking systems The bad news for makers of semiconductor-manufacturing equipment is that sales of most kinds of fab gear are flat to down The good news is that the U.S could end up playing a bigger role supplying manufacturing equipment for the emerging area of solid-state lighting The U.S Dept of Energy used stimulus funds to amplify the supply-chain strengths of the U.S The DOE recognized that the U.S would be an unlikely place for LED fabs, so it tried to seed the development of LED-manufacturing equipment here, explains Tom Morrow, executive vice president, emerging markets group and chief marketing officer for SEMI, the association Will the U S be an ASSEMBLY LEDMECCA?
