NASA Launches Comet-Hunting Space Camera

NASA on Monday successfully launched a space telescope designed to create a highly detailed map of the heavens and spot comets and asteroids that could pose a threat to life on Earth.

NASA’s Wide-field Infrared Survey Explorer, or WISE, lifted off from California’s Vandenberg Air Force Base atop a Delta II rocket at 6:09 a.m. PST.

“”WISE thundered overhead, lighting up the pre-dawn skies,” said William Irace, mission project manager at NASA’s Jet Propulsion Laboratory, in Pasadena, Calif.

“All systems are looking good, and we are on our way to seeing the entire infrared sky better than ever before,” said Irace.

WISE will use an infrared camera to map the cosmos. The mission calls for the unmanned spacecraft to cover the entire sky one-and-a-half times, until its frozen coolant runs out. NASA hopes it will capture everything from near-Earth asteroids to distant galaxies teeming with stars.

“The last time we mapped the whole sky at these particular infrared wavelengths was 26 years ago,” noted UCLA’s Edward Wright, who is principal mission manager.

“Infrared technology has come a long way since then. The old all-sky infrared pictures were like impressionist paintings—now we’ll have images that look like actual photographs,” said Wright.

WISE is designed to provide information about the size, composition, and texture of near-Earth objects such as comets and asteroids.

“We can help protect our Earth by learning more about the diversity of potentially hazardous asteroids and comets,” said Amy Mainzer, deputy project scientist for the mission at JPL.

WISE will also attempt to document the cycle of life in the Universe, as it will capture faraway images of star-hatching galaxies and ravenous, planet-eating black holes.

Internet Turns 40 Today: First Message Crashed System

Everyone surfing for last-minute Halloween costumes and pictures of black Lolcats today—what you might call the 40th anniversary of the Internet—can give thanks to the simple network message that started it all: “lo.”

On October 29, 1969, that message became the first ever to travel between two computers connected via the ARPANET, the computer network that would become the Internet.

The electronic dispatch was supposed to be the word “login,” but only the first two letters were successfully sent before the system crashed.

Still, that humble greeting marked the start of a phenomenon that has become such an important part of modern life that many experts argue access to it should be a right rather than a privilege.

ARPANET — The First Internet

The ARPANET was the first wide area packet switching network, the “Eve” network of what has evolved into the Internet we know and love today.

The ARPANET was developed by the IPTO under the sponsorship of DARPA, and conceived and planned by Lick Licklider, Lawrence Roberts, and others as described earlier in this section.

The ARPANET went into labor on August 30, 1969, when BBN delivered the first Interface Message Processor (IMP) to Leonard Kleinrock’s Network Measurements Center at UCLA. The IMP was built from a Honeywell DDP 516 computer with 12K of memory, designed to handle the ARPANET network interface. In a famous piece of Internet lore, on the side of the crate, a hardware designer at BBN named Ben Barker had written “Do it to it, Truett”, in tribute to the BBN engineer Truett Thach who traveled with the computer to UCLA on the plane.

The UCLA team responsible for installing the IMP and creating the first ARPANET node included graduate students Vinton Cerf, Steve Crocker, Bill Naylor, Jon Postel, and Mike Wingfield. Wingfield had built the hardware interface between the UCLA computer and the IMP, the machines were connected, and within a couple of days of delivery the IMP was communicating with the local NMC host, an SDS Sigma 7 computer running the SEX operating system. Messages were successfully exchanged, and the one computer ARPANET was born.

. . .

The first full ARPANET network connection was next, planned to be with Douglas Engelbart’s NLS system at the Stanford Research Institute (SRI), running an SDS-940 computer with the Genie operating system and connected to another IMP. At about 10:30 PM on October 29’th, 1969, the connection was established over a 50 kbps line provided by the AT&T telephone company, and a two node ARPANET was born. As is often the case, the first test didn’t work flawlessly, as Kleinrock describes below:

At the UCLA end, they typed in the ‘l’ and asked SRI if they received it; ‘got the l’ came the voice reply. UCLA typed in the ‘o’, asked if they got it, and received ‘got the o’. UCLA then typed in the ‘g’ and the darned system CRASHED! Quite a beginning. On the second attempt, it worked fine!

Below is a record of the first message ever sent over the ARPANET.
