> As a young teen I read the manuals for a (defunct) satellite old retired engineer had, funny as electronics hobbyist I could understand it.

:-) I've been there, too. My first computer was an IBM 1130, with 8kB of 'ram'. From what I can tell, here, we have 0kB and all hard-wired to the devices attached to the receivers and transmitters. The satellite just 'talks' via the transmitter and Earth has to listen, or lose the data. That is "how it was" in 1978 (earlier for the finalisation of the design, and the satellite's set-up of the NSA Deep Space Network ground stations).

+ - ISEE-3 satellite is back in control

Submitted by brindafella
brindafella (702231) writes "In the last two days, the (Reboot Project for the International Sun/Earth Explorer 3 (ISEE-3) satellite has commanded ISEE-3 from the Earth, using signals transmitted from the Aricebo Observatory. Signals were also received by cooperating dishes: the 21-meter dish located at Kentucky's Morehead State University Space Science Center; the 20-meter dish antenna in Bochum Observatory, Germany, operated by AMSAT Germany; and, SETI's Allen Telescope Array (ATA), California. ISEE-3 was launched in 1978, and last commanded in 1999 by NASA. On May 15, 2014, the project reached its crowdfunding goal of US$125,000, which will cover the costs of writing the software to communicate with the probe, searching through the NASA archives for the information needed to control the spacecraft, and buying time on the dish antennas. The project then set a "stretch goal" of $150,000, which it also met with a final total of $159,502 raised. The goal is to be able to command the spacecraft to fire its engines to enter an Earth orbit, and then be usable for further space exploration. This satellite does not even have a computer; it is all "hard-wired"."

That name, Siding Spring, comes from the name of Siding Spring Observatory, the most significant optical observatory in Australia, operated by the Australian National University. The mountain is part of the Warrumbungle Range, in the state of New South Wales, near the town Coonabarabran. It is the site of the Anglo-Australian Telescope, among others.

In the case cited, a business card slipped into the case/box/etc can be a quick identifier. Folded if necessary for a smaller item. For people who don't normally have business cards, then make some for such instances out of card stock or printer paper, and cut along the lines. Most office or publishing programs will help you design and print cards. A hand-written card is also okay, and might even be better in the instance mentioned.

+ - Fishing line as artificial 'muscle'->

Submitted by brindafella
brindafella (702231) writes "Researchers have made what they describe as an "almost embarrassing" discovery, that twisted nylon fishing line can form a "powerful, large-stroke, high-stress artificial muscles" capable of lifting as much as 100 times more weight than human muscles and contracting by 49%, and "generate 5.3 kilowatts of mechanical work per kilogram of muscle weight, similar to that produced by a jet engine." They twisted the fishing line, then heated it to 'set' the shape-memory muscle. The scientists are from the Australian Research Centre of Excellence for Electromaterials Science at the University of Wollongong, and the University of Texas. It's published in Science magazine."

Submitted by brindafella
brindafella (702231) writes "Research from James Cook University's Dr Robin Beaman has aggregated data into a new high-resolution bathymetry model of the Great Barrier Reef and Coral Sea, called gbr100. The 100 metre-resolution gridded bathymetry dataset covers an area of about 3,000,000 km2, from the Gulf of Papua to northern New South Wales, and easterly into the deep Coral Sea. There is also a really interesting colour poster (909kB PDF) to download."

+ - Lowell Observatory pushes to name an asteroid "Travyon"->

Submitted by Flash Modin
Flash Modin (1828190) writes "The observatory where Pluto was discovered is pushing to name an asteroid after a black teenager killed in a controversial confrontation in Florida last year.

William Lowell Putnam III says his family is identified with the cause of African American rights, and thus an asteroid named after Trayvon Martin is perfectly appropriate. Putnam is the sole trustee of the observatory, which was founded by Percival Lowell during his search for canals on Mars.

Astronomers at the observatory discovered the asteroid in 2000, but it has not been formally named.

Putnam has already asked the Minor Planet Center once to designate the asteroid "Trayvon," but they told him the designation was "premature." Now that there's been a verdict, the observatory is reapplying in hopes the naming body will see things different."

+ - Open Source Photometry Code Allows Amateur Astronomers To Detect Exoplanets

Submitted by Anonymous Coward
An anonymous reader writes "Have access to a telescope with a CCD? Now you can make your very own exoplanet transit curves. Brett Morris, a student from the University of Maryland, has written an open source photometry application known as Oscaar. In a recent NASA Press Release, Morris writes: "The purpose of a differential photometry code – the differential part – is to compare the changes in brightness of one star to another nearby. That way you can remove changes in stellar brightness due to the Earth's atmosphere. Our program measures the brightness change of all the stars in the telescope's field of view simultaneously, so you can pull out the change in brightness that you see from the planet-hosting star due to the transit event." The program opens up exoplanet-observing to amateur astronomers and undergraduate students across the globe."

There was a time when Slashdot was for people to bring interesting and informative things, or to ask good questions and get good advice. (That is why I bothered to submit this report of a world-first procedure.)
