Who Has the Best Space Plan: Gingrich, Obama or Romney?
Posted by Val in Space and Satellites on February 2, 2012
Forget about presidential politics for a moment. Forget left and right, Republican and Democrat. Forget the GOP primaries and the same tired old debates that have filled the opinion pages for the last four years.
Instead, to determine the next occupant of the White House, try this question on for size: Would you rather build a moon base or start mining the asteroid belt? Or do you think space exploration should be de-emphasized, and that NASA should be run with the help of the business community?
If you favor the moon base, you’re with Republican hopeful Newt Gingrich. The former speaker, a self-confessed space nerd, made that announcement while campaigning Thursday on Florida’s space coast. “By the end of my second term,” he said, “we will have the first permanent base on the moon, and it will be American.”
Former president George W. Bush also directed NASA to aim for a moon base by 2020. (There’s a commercial purpose to this; the moon is likely full of helium-3, a potential energy source for the fusion reactors of the future.) That plan was scrapped by President Obama, who favors sending a manned mission to an asteroid instead.
The asteroid belt is full of minerals such as iron, cobalt and platinum, each worth trillions of dollars Indeed, the worth of a single M-class rock has been conservatively estimated at $10 trillion. Obama wants NASA to put astronauts in that ballpark by 2025.
Both Gingrich and Obama want humans on Mars in the 2030s. Obama wants NASA to take the lead on that, while Gingrich favors cutting the space agency’s budget by 10% and giving that money to the private sector — in the form of a $10 billion prize for the first organization to land on Mars.
And Romney? Gingrich’s rival in the GOP contest has been far less specific about his space plans. But in a recent debate, he suggested his first step would be to have NASA partly funded by commercial interests. “Bring them together, discuss a wide range of options for NASA,” Romney said. “Let’s have a collaborative effort.”
Romney has also said he favors an Apollo-like mission to “excite young people about the potential of space,” but hasn’t said where that mission should go to.
So whose space policy sounds the smartest? Take our poll below, and sound off in the comments.
ATI’s Top 5 Engineering Course Samplers of 2011
Posted by admin in Acoustics & Sonar, Analysis and Signal Processing, Defense, Including Radar, Missiles and EW, ENGINEERING, Space and Satellites, Systems Engineering and Project Management on February 1, 2012

What Are the Tools of Your Trade?
Our mission here at the Applied Technology Institute (ATI) is to provide expert training and the highest quality professional development in space, communications, defense, sonar, radar, and signal processing. We are not a one-size-fits-all educational facility. Our short classes include both introductory and advanced courses.
ATI’s Top Five Engineering Courses for 2011
The five engineering courses for 2011 are highlighted below:
#1 Practical Statistical Signal Processing – using MATLAB
This 4-day course covers signal processing systems for radar, sonar, communications, speech, imaging and other applications based on state-of-the-art computer algorithms. These algorithms include important tasks such as data simulation, parameter estimation, filtering, interpolation, detection, spectral analysis, beamforming, classification, and tracking. Until now these algorithms could only be learned by reading the latest technical journals. This course will take the mystery out of these designs by introducing the algorithms with a minimum of mathematics and illustrating the key ideas via numerous examples using MATLAB.
Designed for engineers, scientists, and other professionals who wish to study the practice of statistical signal processing without the headaches, this course will make extensive use of hands-on MATLAB implementations and demonstrations. Attendees will receive a suite of software source code and are encouraged to bring their own laptops to follow along with the demonstrations.
#2 Advanced Topics in Digital Signal Processing
This four-day course is designed for communication systems engineers, programmers, implementers and managers who need to understand current practice and next generation DSP techniques for upcoming communication systems. DSP is more than mapping legacy analog designs to a DSP implementation. To avoid compromise solution appropriate for an earlier time period, we return to first principles to learn how to apply new technology capabilities to the design of next generation communication systems.
#3 Engineering Systems Modeling WithExcel/VBA
This two-day course is for engineers, scientists, and others interested in developing custom engineering system models. Principles and practices are established for creating integrated models using Excel and its built-in programming environment, Visual Basic for Applications (VBA). Real-world techniques and tips not found in any other course, book, or other resource are revealed. Step-bystep implementation, instructor-led interactive examples, and integrated participant exercises solidify the concepts introduced. Application examples are demonstrated from the instructor’s experience in unmanned underwater vehicles, LEO spacecraft, cryogenic propulsion systems, aerospace & military power systems, avionics thermal management, and other projects.
#4 Wavelets: A Conceptual, Practical Approach
Fast Fourier Transforms (FFT) are in wide use and work very well if your signal stays at a constant frequency (“stationary”). But if the signal could vary, have pulses, “blips” or any other kind of interesting behavior then you need Wavelets. Wavelets are remarkable tools that can stretch and move like an amoeba to find the hidden “events” and then simultaneously give you their location, frequency, and shape. Wavelet Transforms allow this and many other capabilities not possible with conventional methods like the FFT.
This course is vastly different from traditional math-oriented Wavelet courses or books in that we use examples, figures, and computer demonstrations to show how to understand and work with Wavelets. This is a comprehensive, in-depth, up-to-date treatment of the subject, but from an intuitive, conceptual point of view. We do look at a few key equations from the traditional literature but only AFTER the concepts are demonstrated and understood. If desired, further study from scholarly texts and papers is then made much easier and more palatable when you already understand the fundamental equations and how they relate to the real world.
#5 Computational Electromagnetics
This 3-day course teaches the basics of CEM with application examples. Fundamental concepts in the solution of EM radiation and scattering problems are presented. Emphasis is on applying computational methods to practical applications. You will develop a working knowledge of popular methods such as the FEM, MOM, FDTD, FIT, and TLM including asymptotic and hybrid methods. Students will then be able to identify the most relevant CEM method for various applications, avoid common user pitfalls, understand model validation and correctly interpret results. Students are encouraged to bring their laptop to work examples using the provided FEKO Lite code. You will learn the importance of model development and meshing, post- processing for scientific visualization and presentation of results.

U.S. Must Take Space Storm Threat Seriously, Experts Warn
Posted by admin in Space and Satellites on January 26, 2012
A severe solar storm has the potential to take down telecommunications and power grids, and the country needs to work on being better prepared, said NOAA administrator Jane Lubchenco here at the annual meeting of the American Association for the Advancement of Science. Lubchenco is also the U.S. Under Secretary of Commerce for Oceans and Atmosphere.
“This is not a matter of if, it’s simply a matter of when and how big,” Lubchenco said of the potential for a dangerous solar flare. “We have every reason to expect we’re going to be seeing more space weather in the coming years, and it behooves us to be smart and be prepared.”
The space weather threat is becoming more dire as our sun ramps up toward its period of solar maximum, predicted for around 2013. Activity on the sun fluctuates on a roughly 11-year cycle, and our star has been relatively dormant for a while.
That’s clearly starting to change, though, as evidenced by a class X solar flare – the strongest kind – that erupted from the sun Feb. 14.
“I think the events of this week certainly underscore how important it is for us to be paying attention to space weather and to be prepared to respond to, and mitigate, potential impacts,” Lubchenco said. “As we enter into a period of enhanced solar activity it seems pretty clear that we are going to be looking at the possibility of not only more solar events but also the possibility of some very strong events.”
The Feb. 14 flare unleashed a wave of charged particles that streamed immediately toward Earth, as well as coronal mass ejections, or blobs of plasma, that took days to arrive here. When they did, they interacted with Earth’s magnetic field to cause geomagnetic storms that wiped out radio communications in the Western Pacific Ocean and parts of Asia, and caused airlines to reroute some polar flights to avoid radio outages.
NEXT TIME COULD BE WORSE
However, experts say we got off fairly lucky with this recent solar storm, and that future eruptions could cause worse damage, particularly to the sensitive transformers and capacitors in power grids. If some of these were harmed, there could be power outages for days, weeks, months, or even, in the case of severe damage, years, experts warned.
“It turned out that we were quite well protected this time, so not much happened,” said European Space Agency scientist Juha-Pekka Luntama. “In another case things might have been different.”
Space weather hasn’t posed quite such a threat before, because during the last solar maximum, around 10 years ago, the world wasn’t as dependent on satellite telecommunications, cell phones and global positioning system (GPS) – all technologies that could be disrupted by solar flares.
“Many things we take for granted today are so much more prone to the effects of space weather than was the case during the last maximum,” Lubchenco said. The problem is likely to get even worse as the world could likely become more technologically dependent by the time the next solar maximum rolls around, and the next.
Russia Talks Of Permanent Moon Base
Posted by admin in Space and Satellites on January 19, 2012
Russia’s space agency Roscosmos says it is in talks with European and U.S. partners about creating permanent manned research bases on the moon.
“We don’t want the man to just step on the moon,” Roscosmos chief Vladimir Popovkin said in a radio interview Thursday.
“Today, we know enough about it, we know that there is water in its polar areas,” he said, and “we are now discussing how to begin [the moon's] exploration with NASA and the European Space Agency.”
Talk of a base harkens back to Cold War-era plans to create a permanent outpost on the moon, a subject of interest to Soviet and U.S. scientists since the late 1950s, RIA Novosti reported.
Popovkin mentioned two options, to “either to set up a base on the moon or to launch a station to orbit around it.”
Russia is proceeding with plans to send two unmanned missions to the moon by 2020, the Luna Glob and the Luna Resource.

Russia’s Phobos-Ground To Crash Into Indian Ocean
Posted by Val in Space and Satellites on January 12, 2012
Russia’s space agency predicts that the fragments of a failed Russian space probe’s could fall into the Indian Ocean, far away from any populated areas.
Roscosmos said yesterday that the Phobos-Ground’s debris could fall between Saturday and Monday anywhere along a broad swath between 51.4 degrees north to 51.4 degrees south.
That includes the bulk of the land surface, but spares most of Russia’s territory along with Scandinavia and a large part of Canada.
The agency said the mid-point in the three day window at 1448 IST Sunday when fragments could come crashing down correspond to a place in the Indian Ocean, about 1,700 kilometres west of Jakarta.
Roscomos said, however, that the forecast will be clarified as the probe’s orbit draws closer to Earth.

Thanks to some Tweeter happy astronauts and a new camera technology that was able to shoot high-resolution photos even as the station moved at a rapid 17,500 miles an hour some 240 miles above Earth’s surface.
The amazing photo tweets were first noticed in 2010 by author L. Douglas Keeney. He went through 300,000 NASA images and chose the best 400 photos for his book Lights of Mankind: The Earth at Night as Seen from Space.
Here are just a few of them. Enjoy!

Will Air Force’s Secret Robot Space Plane Be Spying on China?
Posted by Val in Space and Satellites on January 5, 2012
The U.S. Air Force’s top secret X-37B space plane may be spying on China, according to a report in Spaceflight magazine.
The unmanned craft was launched into Earth’s orbit 10 months ago, but the Air Force has kept quiet on its mystery mission, where it’s been, and when it will return. Faithful onlookers now believe the space plane might be snooping on China’s new space station, Tiangong-1 — after discovering how closely their orbits matched.
The U.S. Air Force launched the robotic X-37B space plane in early 2010 on a space mission that remains a secret — even after the craft touched ground 225 days later at Vandenberg Air Force Base. In early 2011, the ship took off again on its latest mission.
“Space-to-space surveillance is a whole new ball game made possible by a finessed group of sensors and sensor suites, which we think the X-37B may be using to maintain a close watch on China’s nascent space station,” Spaceflight Editor Dr. David Baker told the BBC.
Built by Boeing’s Phantom Works division, the 29-foot-long X-37B spacecraft was originally developed by NASA in 1999 before it was eventually taken over and classified by the Defense Advanced Research Projects Agency (DARPA).
The robot craft’s official purpose is to test new spaceflight technologies but there has been speculation about X-37B’s potential military capabilities with Iran’s PressTV calling the vehicle a “secret space warplane” — an opinion partly echoed by Brian Weeden, a technical adviser to the Secure World Foundation and a former orbital analyst with the U.S. Air Force.
Weeden suspects that the X-37B may be testing out gear for the National Reconnaissance Office, the intelligence agency that builds and operates the U.S.’s spy satellites — which would explain the secrecy.
“As we know through experience, everything and anything about them [the NRO] is classified,” Weeden told Space.com early last year.
The space plane, also known as the Orbital Test Vehicle-2, was boosted into Earth orbit atop an Atlas 5 rocket from Cape Canaveral, Fla., on March 5, 2011, and amateur skywatchers have been keenly tracking it ever since.
“The parallels with X-37B [and Tiangong-1] are clear,” Baker said in this month’s Spaceflight. “With a period differential of about 19 seconds, the two vehicles will migrate toward or against each other, converging or diverging, roughly every 170 orbits.”
But Weeden and others believe the orbital similarities between the two could be a red herring.
“A typical spy satellite is in a polar orbit, which gives you access to the whole Earth,” Weeden told the BBC.
“The X-37B is in a much lower inclination which means it can only see a very narrow band of latitudes — and the only thing that’s of real interest in that band is the Middle East and Afghanistan.”
China’s Ambitious Space Plans: What are they and can they be achieved by 2016?
Posted by Val in Space and Satellites on December 29, 2011
Yesterday, China unveiled its space plans up to 2016. One of the most ambitious ones is to put an astronaut on the surface of the Moon. This feat hasn’t been accomplished since 1972 with Gene Cernan being the last to step off the lunar surface (Appolo 17).
What are China’s plans?
- Launch space labs and manned ships and prepare to build space stations over the next five years
- Continue exploring the moon using probes, start gathering samples of the moon’s surface, and “push forward its exploration of planets, asteroids and the sun.”
- Improve its launch vehicles, improve its communications, broadcasting and meteorological satellites and develop a global satellite navigation system, intended to rival the United States’ dominant global positioning system (GPS) network
- Use spacecraft to study the properties of black holes and begin monitoring space debris and small near-Earth celestial bodies and build a system to protect spacecraft from debris
Can China pull it off?
It is quite possible since China has been make remarkable progress in this area in recent years.
In 2003, China became the third country behind the U.S. and Russia to launch a man into space and, five years later, completed a spacewalk. Toward the end of this year, it demonstrated automated docking between its Shenzhou 8 craft and the Tiangong 1 module, which will form part of a future space laboratory.
In 2007, it launched its first lunar probe, Chang’e-1, which orbited the moon, collecting data and a complete map of the moon.
Since 2006, China’s Long March rockets have successfully launched 67 times, sending 79 spacecraft into orbit.
What does this mean for us?
Some elements of China’s program, notably the firing of a ground-based missile into one of its dead satellites four years ago, have alarmed American officials and others who say such moves could set off a race to militarize space. That the program is run by the military has made the U.S. reluctant to cooperate with China in space, even though the latter insists its program is purely for peaceful ends.
Soyuz Spacecraft Heads For International Space Station
Posted by admin in Space and Satellites on December 21, 2011
A Soyuz spacecraft carrying a Russian, an American and a Dutchman to the International Space Station blasted off flawlessly from Russia’s launch facility in Kazakhstan on Wednesday.
Mission commander Oleg Kononenko and his colleagues, American Don Pettit and European Space Agency astronaut Andre Kuipers are to dock with the space station on Friday.
The blastoff from the snowy launchpad in Baikonur, Kazakhstan, took place without a hitch and the spacecraft reached Earth orbit about nine minutes later. Video from inside the craft showed the three crew members gripping each others’ hands in celebration as the final stage of the booster rocket separated.
The three aboard the Russian spacecraft will join three others already on the ISS, NASA’s Dan Burbank and Russians Anton Shkaplerov and Anatoly Ivanishin. The six are to work together on the station until March.
The launch came amid a period of trouble for Russia’s space program, which provides the only way for crew to reach the space station since the United States retired its space shuttle program in July.
The launch of an unmanned supply ship for the space station failed in August and the ship crashed in a Siberian forest. The Soyuz rocket carrying that craft was the same type used to send up Russian manned spacecraft, and the crash prompted officials to postpone the next manned launch while the rockets were examined for flaws. The delayed mission eventually took place on Nov. 14.
Just five days before that launch, Russia sent up its ambitious Phobos-Ground unmanned probe, which was to go to the Phobos moon of Mars, take soil samples and return them to Earth. But engineers lost contact with the ship and were unable to propel it out of Earth orbit and toward Mars. The craft is now expected to fall to Earth in mid-January.
Last December, Russia lost three navigation satellites when a rocket carrying them failed to reach orbit. A military satellite was lost in February, and the launch of the Express-AM4, described by officials as Russia’s most powerful telecommunications satellite, went awry in August.
