Comment Deep Space starts where? Politics, once again. (Score 5, Informative) 179

So here is the story: inside NASA, "Deep Space" used to mean (prior to 2003) anything beyond the orbit of the Moon. This was intended to be the domain of work for science and telecommunications ops of the Jet Propulsion Laboratory (JPL), an FFRDC operated by Caltech as a NASA center. Inside the Moon's orbit was the domain of scientific work for NASA's Goddard Space Flight Center (GSFC). This included Earth observing science and telecom as well as astrophysics spacecraft. During the Constellation program, when simply returning to the Moon was not enough justification for the program and seeking a way to justify control of the design of deep space telecom for manned spaceflight, the Constellation Program Office at NASA Johnson Space Center (JSC) and NASA GSFC sought to redefine deep space as anything beyond HEO. This was also an attempt by GSFC to put JPL's Deep Space Interplanetary Network (aka "DSN) on the sideline of the design process for Constellation deep space telecom. (Furthermore, GSFC at the time was lobbying to get new Earth orbiting telecom spacecraft launched and needed additional justification, ergo "they are good for Constellation"). I don't think the issue was every resolved one way or another as far as "official" definitions go and in the end, not much changed before Constellation was cancelled. The lesson is this: Words like "deep space" can mean a lot when government research centers are fighting to protect their charters and business base. I'm glad I'm out of that biz!

Comment Nothing new here; just politics (Score 5, Informative) 179

This is simply a rebranded Orion capsule. I worked on Constellation (from inside NASA) for years and helped the program get started. There is no rocket to launch the capsule. There is no mission for it. Nothing on the books, nothing remotely near ready for approval. Just how "deep" into space will it go with a mission time of 21 days? Hint: The Moon is not "deep space". Mars is deep space. Mars is at least 6 months away - one direction. Finally, how many times (altogether now) have we heard "advanced avionics"? That means they are up to Web 0.42 now, maybe. Bottom line: This is pure pork for Lockheed-Martin (Lockheed HQ is in Maryland; Dem. Senator Mikulski is on the Appropriation Committee). It is a multiple billion dollar gift. It will never fly. Ever. I'll bet a fair share of the related jobs go to Houston and to Huntsville, AL (Rep. Sen. Shelby, also on the Appropriations committee).

No they won't. g-mod organisms, stem cell research, cloning, synthetic biology, ethical treatment of robots ... none of these issue will ever be something that comes before voters. No decisions by voters matter. Scientific advance and technological engineering HAPPENS. All this will simply be part of the emerging future. The tragedy is the danger of a populace ill equipped to deal with it.

It depends on what you want to do. If you want to communicate with other people nearby in the city, then peer-to-peer networking is the way to do it. Set up mobile hotspots with open access. With VoIP you can even use your mobile handsets. Vulnerable to jamming, snooping and RDF. If you want to reconnect with the global network, then a satellite link is one way, or packet data over ham freq, maybe bounced off the ionosphere.

Comment Automotive technology security concerns (Score 1) 344

There are upward of 70 microprocessors, 20 million lines of code (if you include multimedia tech) and hundreds of I/O ports in a typical upscale modern car. Manufacturers are moving towards in-car wireless networking to replace the enormous amount of cabling that current exists. Researchers have already demonstrated to seize control of the engine and brakes by hacking a couple of 2009 model year cars. http://www.newscientist.com/article/dn18901-modern-cars-vulnerable-to-malicious-hacks.html Considering that they won't let me use my ipod on an aircraft during takeoff and landing because IT MIGHT CRASH (tell me about it), yeah, count me worried about automobiles and other transportation as well.

Transcranial Magnetic Stimulation of the brain using induced currents has been around for quite a while. Google it. TMS of certain regions of the brain can induce spiritual feelings (in the religious sense). That said, TMS is a procedure for studying the brain, and uses sophisticated and precisely calibrated equipment you are unlikely to find in a haunted house!

September Is Cyborg Month 118

Snowmit writes "In May 1960, Manfred E. Clynes and Nathan S. Kline presented a paper called 'Drugs, Space, and Cybernetics.' The proceedings of the symposium were published in 1961, but, before that, an excerpt of Clynes & Kline's paper appeared in the September issue of Astronautics magazine (issue 13), entitled Cyborgs and Space [PDF]. Aside from a mention in the New York Times, that's is the first time the word appears in print. This month is the 50th anniversary of that article. To commemorate, a group of writers and artists have gotten together to create 50 Post About Cyborgs. Over the course of the month, there will be essays, fiction, links to great older material, comics, and even a song. We're going to talk about Daleks, IEDs, Renaissance memory palaces, chess computers, prosthetic imagination, Videodrome, mutants, sports, and maybe the Bible. To kick things off, Kevin Kelly wrote this essay arguing that we've been cyborgs all along."

The Sun Unleashes Coronal Mass Ejection At Earth 220

astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

Comment 1995: SKICAT System classified galaxies (Score 1) 40

Sorry to burst the bubble, but automatic classification of galaxies from sky survey data using machine learning techniques was accomplished in the early '90s by the SKICAT system developed at JPL and Caltech. http://adsabs.harvard.edu//abs/1995PASP..107.1243W is a good overview of the system and its accomplishments as of 1995.

RFID Checks Student Attendance in Arizona 554

The student newspaper at UW-Madison is running a piece about the use of RFID to check lecture attendance at Northern Arizona University. One poster to an email discussion list suggested that getting around this system would be simple if "all one has to do is walk into a classroom with 10 RFID-enabled cards in their pocket." "The new system will use sensors to detect students' university identification cards when they enter classrooms, according to NAU spokesperson Tom Bauer. The data will be recorded and available for professors to examine. ... [The spokesman] added the sensors, paid for by federal stimulus money, initially would only be installed in large freshmen and sophomore classes with more than 50 students. NAU Student Body President Kathleen Templin said most students seem to be against the new system. She added students have started Facebook groups and petitions against the sensor system. ... One of the most popular Facebook groups ... has more than 1,400 members." What are the odds that the use of tracking RFID will expand over time on that campus?
