The ISS celebrated 15 years in orbit this week.
Astronaut James H. Newman waves during a spacewalk preparing for release of the first combined elements of the International Space Station. The Russian-built Zarya module, with its solar array panel visible here, was launched into orbit fifteen years ago on Nov. 20, 1998. Two weeks later, on Dec. 4, 1998, NASA’s space shuttle Endeavour launched Unity, the first U.S. piece of the complex. Endeavour’s forward section is reflected in Newman’s helmet visor in this image. During three spacewalks on the STS-88 mission, the two space modules built on opposite sides of the planet were joined together in space, making the space station truly international.
In support of station assembly and maintenance, station and shuttle crews have conducted 174 spacewalks totaling almost 1,100 hours – the equivalent to nearly 46 days of spacewalks to build and maintain the complex. The station, with a mass of almost a million pounds and the size of a football field, is second only to the moon as the brightest object in the night sky.
Pac-Man sets new world record.
According to the Namco Bandai Twitter account, the record was set yesterday:

I don’t think it looks bigger than this 29 story-high game of Pong, but perhaps that game wasn’t officially going for a record.
This is the Cassiopeia A supernova remnant, as captured by NASA’s Chandra X-ray Observatory. It shows the 300-year old remains of a stellar explosion that blew a massive star apart, sending the stellar debris rushing into space at millions of miles per hour.
A European team has found a way to create beams of light that focus more intensely as they travel, forming what looks like a bullet out of light.
Rates of US Adoption of Consumer Technologies
This chart tracks rates of adoption from 10% to 90% penetration in the US.
The interesting trend here is that the lines are getting more and more vertical, indicating that new technologies are becoming adopted faster as time goes on.
