CubeSat Launch Visible Around U.S. East Coast Tonight
Hugh Pickens DOT Com writes "Brad Lendon reports at CNN that 29 satellites, the most ever launched at one time, will be aboard a single Minotaur I rocket scheduled to lift off from NASA's Wallops Flight Facility in Virginia Tuesday night at 7:30 pm. The main payload will be the Air Force's Space Test Program Satellite-3, plus 28 tiny satellites called CubeSats about 4 inches on each side, weighing about 3 pounds and with a volume of about a quart. The cubesats will include Ho`oponopono-2 from the University of Hawaii to continue a long-existing radar calibration service for the 80 plus C-band radar tracking stations distributed around the world. It will also have CAPE-2 from the Cajun Advanced Picosatellite Experiment, to give students at the University of Louisiana at Lafayette the opportunity to research, design, develop, and maintain a low earth orbiting satellite, and SwampSat from the University of Florida to advance the TRL (Technology Readiness Level) of CMGs (Control Moment Gyroscopes) appropriate for smallsats. Among the CubeSats is the TJ3Sat, the first satellite made by high-schoolers to go into space, built by the students of Thomas Jefferson High School for Science and Technology in Alexandria, Virginia. It will give students and other amateur radio users the opportunity to send and receive data from the satellite. Approved text strings will be transmitted to the satellite, and the resulting voice interpretation will be relayed back to Earth over an amateur radio frequency using the onboard Stensat radio. Orbital says the 29 satellites should achieve orbit in a little less than 12½ minutes after the rocket ignites. NASA says the launch may be visible from northern Florida to southern Canada and as far west as Indiana. Live coverage of the launch is available via UStream beginning at 6:30 p.m. EST on launch day." -
Malicious E-Cards - An Analysis of Spam
smashr writes "I ran across this article the other day which is a rather clear analysis of a piece of malicious spam the author received. While most of us simply hit the delete key, the author has taken the time to see exactly what is going on when an innocent user clicks on one of these fake e-cards that are going around. From Russian spyware sites to over-writing wmplayer.exe this particular piece of spam is a rather nasty one." -
Game of Life in Postscript
smashr writes "It never really occured to me that postscript could be used for something other than printing, until I came across this page. Evidently someone has written the classic 'Game of life' entirely in postscript. You can even send it to the printer and have it output every single iteration.. now that would be a fun prank."
