  • The shape is a 10cm cube, and the weight is 1.33kg.
  • The main mission of this satellite is to demonstrate the high speed transmitter developed. It can send a jpeg VGA-picture(480x640) within 6 seconds
  • NIWAKA will write messages in the night sky with Morse code as: (JAXA movie 120MB)

  • ultrasmall satellites it's carrying, which are known as cubesats, will likely remain on the orbiting lab until September
  • using the Kibo module's robotic arm.
  • One of the cubesats, FITSAT-1, will write messages in the night sky with Morse code, helping researchers test out optical communication techniques for satellites, researchers said.
  • One of FITSAT-1's experimental duties is to twinkle as an artificial star
  • just under 3 pounds (1.33 kilograms
  • high power light-emitting diodes (LEDs) that will produce extremely bright flashes.
  • hope, will be observable by the unaided eye or with small binoculars
  • the cubesat's high-output LEDs will blink in flash mode, generating a Morse code beacon signal.
  • contains a neodymium magnet that forces it to always point to magnetic north, like a compass.

  • ...9 more annotations...
  • rode his specially-made pressurized capsule via a helium balloon and jumped from an altitude of over 29,455 meters (96,640 feet), falling for 3 minutes, 48 seconds, reaching speeds of 862 km/h (536 mph).
  • this is the final milestone before his attempt of jumping from 36,500 meters (120,000 feet), to break the current jump record held by Joe Kittinger a retired Air Force officer – and Baumgartner’s current adviser and mentor — who jumped from 31,500 m (31.5 km, 19.5 miles) in 1960.
  • test launch was twice delayed due to bad weather
  • balloon took about 90 minutes to reach the desired altitude
  • floated down on his parachute for about eight minutes
  • landed in the New Mexico desert, just about 15 minutes by helicopter from his launch site
  • balloon over four times as large as the one that carried Baumgartner for the first test flight in March
  • did not provide an official date for the record-setting attempt
  • it is now subject to favorable weather conditions and critical post-jump assessments of the capsule and equipment

  • quantitative analysis of nearly half a million songs
  • songs from nearly 45,000 artists
  • Of the million songs therein, 464,411 came out between 1955 and 2010
  • ...15 more annotations...
  • examined three aspects of those songs: timbre (which “accounts for the sound color, texture, or tone quality,” according to Serrà and his colleagues); pitch (which “roughly corresponds to the harmonic content of the piece, including its chords, melody, and tonal arrangements”); and loudness
  • peaking in the 1960s, timbral variety has been in steady decline to the present day
  • implies a homogenization of the overall timbral palette, which could point to less diversity in instrumentation and recording techniques
  • Musicians today seem to be less adventurous in moving from one chord or note to another, instead following the paths well-trod
  • no surprise that music has gotten louder
  • the same notes and chords that were popular in decades past are popular today
  • found that the loudness of recorded music is increasing by about one decibel every eight years
  • The Million Song Dataset, huge as it is, may not provide a representative slice of pop music, especially for old songs
  • heavily weighted to modern music
  • only 2,650 songs released between 1955 and 1959
  • 177,808 songs—released between 2005 and 2009
  • draws on what’s popular now, as well as what has been digitized and made available for download
  • may not be the same ones that people enjoyed when those songs first came out.
  • the trend is consistent in short time spans
  • also consistent for longer time spans

  • eye-writing technology tricks the neuromuscular machinery into doing something that is usually impossible: to voluntarily produce smooth eye movements in arbitrary directions
  • ...8 more annotations...
  • could be of great benefit for people deprived of limb movements, such as those with Lou Gehrig's disease (also known as ALS), the researchers say. It might also help to improve eye movement control in people with certain conditions such as dyslexia or ADHD and/or for experts, such as athletes or surgeons, whose activities strongly rely on eye movements
  • In everyday life, smooth pursuit eye movement is used to track moving targets
  • fact our eyes never cease to move
  • normally impossible to control those movements smoothly in any direction.
  • got a hint that smooth eye movements just might be possible in a completely accidental way
  • technology relies on changes in contrast to trick the eyes into the perception of motion
  • now working on a better version of his eye writer, and tests with ALS patients should start next year
  • He was moving his own eyes in front of an unusual visual display in his lab and discovered that it produced some odd effects. For one thing, he could see his own eye movements. With a little practice, he gradually discovered that he could control those eye movements, too.

  • NASA’s Mars Odyssey will relay near real time signals of this artist’s concept depicting the moment that NASA’s Curiosity rover touches down onto the Martian surface
  • Engines aboard NASA’s long lived Mars Odyssey spacecraft fired for about 6 seconds to adjust the orbiters location about 6 minutes ahead in its orbit. This will allow Odyssey to provide a prompt confirmation of Curiosity’s landing inside Gale crater at about 1:31 a.m. EDT (531 GMT) early on Aug. 6 (10:31 p.m. PDT on Aug. 5) – as NASA had originally planned.
  • Watch NASA TV online for live coverage of Curiosity landing: mars.jpl.nasa.gov or www.nasa.gov
