Scenes from 30,000 meters above

On February 28th, a team of four Spanish teenage students and their instructor from IES La Bisbal school in Catalonia launched a weather probe they designed and built themselves. Their helium-filled balloon carried a payload of electronics and a camera to take atmospheric measurements and photographs throughout the trip. After getting permission from aviation officials and getting good weather, they released the probe on a trip that took it over 30,000 meters (19 miles) above sea level, through winds gusting up to 100 kph, and temperatures reaching -54C (-65.2F), and traveling 38 kilometers overland in a time of 2 hours and 10 minutes. The Meteotek08 team has collected their images and data on both their blog and flickr page, and has kindly given me permission to share these photos here with you. (28 photos total)

Robots

Robotic systems continue to evolve, slowly penetrating many areas of our lives, from manufacturing, medicine and remote exploration to entertainment, security and personal assistance. Developers in Japan are currently building robots to assist the elderly, while NASA develops the next generation of space explorers, and artists are exploring new avenues of entertainment. Collected here are a handful of images of our recent robotic past, and perhaps a glimpse into the near future. (32 photos total)

Twendy-One demonstrates its ability to hold delicate objects by manipulating a drinking straw between its fingers at the Department of Mechanical Engineering laboratory in Waseda University in Tokyo, Japan, Wednesday, Jan. 14, 2009. The sophisticated robot has been developed by the university's team, led by Dr. Shigeki Sugano, in hope of supporting people in aging societies. (AP Photo/Shizuo Kambayashi)

Hubble Space Telescope Advent Calendar 2008

As we head into the traditional western Holiday Season, I'd like to present this Hubble Space Telescope imagery Advent Calendar. Every day, for the next 25 days, a new photo will be revealed here from the amazing Hubble Space Telescope. As I take this chance to share these images of our amazing Universe with you, I wish for a Happy Holiday to all those who will celebrate, and for Peace on Earth to everyone. - Alan (25 photos total - eventually)

In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our galaxy. The star, called V838 Monocerotis, has long since faded back to obscurity, but observations of a phenomenon called a "light echo" around the star have uncovered remarkable new features over the following years (this animation covers two years' time). The light echo is light from the earlier explosion echoing off dust surrounding the star. Light from the outburst traveled to the dust and then was reflected to Earth. Because of this indirect path, the light arrived at Earth months after light from the star that traveled directly from the star. (NASA, ESA) More (see this on Google Sky)

The International Space Station turns 10

This month marks the 10th anniversary of the first launched module of the International Space Station (ISS). The module Zarya was lifted into orbit on November 20th, 1998 by a Russian Proton rocket lifting off from Baikonur, Kazhakstan. In the decade since, 44 manned flights and 34 unmanned flights have carried further modules, solar arrays, support equipment, supplies and a total of 167 human beings from 15 countries to the ISS, and it still has a ways to go until it is done. Originally planned to be complete in 2003, the target date for completion is now 2011. Aside from time spent on construction, ISS crew members work on a good deal of research involving biology and physics in conditions of microgravity. If humans are ever to leave the Earth for extended periods, the ISS is designed to be the place where we will discover the best materials, procedures and safety measures to make it a reality.

In December 1998, the crew of Space Shuttle Mission STS-88 began construction of the International Space Station - Astronaut James Newman is seen here making final connections the U.S.-built Unity node to the Russian-built Zarya module. The crew carried a large-format IMAX camera from which this picture was taken. (NASA)

Peering into the micro world

A team of University of Michigan researchers has recently created a set of electron microscope images of carbon nanotube structures depicting images of U.S. President-elect Barack Obama. John Hart, leader of the research team says it wasn't a political statement, but an attempt to draw attention to what is possible these days with nanotechnology, and imaging at the very small scale. I'll take him up on this invitation and share with you some other images of very tiny things in our world. For visualizing the scale, most measurements below are in microns - one micron is a millionth of a meter - human hair is approximately 100 microns thick. (32 photos total)

Images of U.S. President-elect Barack Obama, each made with approximately 150 million tiny carbon nanotubes, are photographed using an electron microscope by University of Michigan Mechanical Engineering Department in this image released to Reuters November 10, 2008. The image, based on an original drawing by Shepard Fairey, is just wider than 500 microns and is made of approximately 150 million tiny carbon nanotubes, which is about the number of Americans who voted on November 4, according to John Hart at University of Michigan.

The Baikonur Cosmodrome

When NASA's last scheduled Space Shuttle mission lands in June of 2010, the United States will not have the capability to get astronauts into space again until the scheduled launch of the new Orion spacecraft in 2015. Over those five years, the U.S. manned space program will be relying heavily on Russia and its Baikonur Cosmodrome facility in Kazakhstan. Baikonur is an entire Kazakh city, rented and administered by Russia. The Cosmodrome was founded in 1955, making it one of the oldest space launch facilites still in operation. Here are collected some photographs of manned and unmanned launches from Baikonur over the past several years. (26 photos total)

Large Hadron Collider nearly ready

The Large Hadron Collider (LHC), a 27 kilometer (17 mile) long particle accelerator straddling the border of Switzerland and France, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN) is preparing for its first small tests in early August, leading to a planned full-track test in September - and the first planned particle collisions before the end of the year. The final step before starting is the chilling of the entire collider to -271.25 C (-456.25 F). Here is a collection of photographs from CERN, showing various stages of completion of the LHC and several of its larger experiments (some over seven stories tall), over the past several years.
