  • Spaceflightnow.com: Japanese infrared space observatory goes into orbit - Japan launched the ASTRO-F infrared telescope (now named "Akari"). A solar sail was a secondary payload, described (in Japanese) in the ASTRO-F/M-V-8 data sheet. From the article: "Another apparatus catching a ride to space aboard the M-5 rocket was a deployment test mechanism containing a solar sail made of aluminized polymer film that was supposed to deploy a maximum diameter of around 35 feet beginning just over eighteen minutes after liftoff. Two cameras positioned near the device would capture images of the critical unfurling of the solar sail for downlink to the ground. The experiment is a follow-up to a sub-orbital test conducted in 2004."

  • NASA's Centennial Challenges Program Seeks Input On New Prize Competitions. "NASA's Centennial Challenges Program released today draft rules for six new prize competitions. NASA is seeking external comments and collaborating organizations in order to finalize and initiate these Challenges. The six prize competitions encompass a range of capabilities and technologies, including: on-orbit propellant provisioning, lunar astronaut rovers, space suits, advanced power storage, orbital sample return, and solar sails."

  • JAXA: October 25 2005: Solar Radiation Pressure Force acting on Hayabusa Station Keeping "Hayabusa has kept its position controlled since it arrived at the Gate Position, 20 km from Itokawa. The biggest disturbance worked is the Solar Radiation Pressure force. The force is simply Light Force acting on everyone everyday. From bright walls, also from heaters, we receive this small force that is never felt on the ground. It is due to the photons that come from the Sun or anything illuminating. The force becomes large when the projected area becomes large and also when the exposed surface has high reflectivity. It is 1/100 with respect to the ion engines thrust, but ten times larger than the gravity of Itokawa at the Home Position."

Google News story] if you have trouble reading the official release. L'Garde was selected to conduct further studies of their solar sail technology for the next phase of the New Millenium Space Technology 9 (ST9) mission. After their studies and those of the other technology providers are complete, one technology will be selected to fly as ST9.

  • The Plain Dealer: Setting sail on sun-power research: Technology for space travel being tested in a vacuum in Sandusky, by Madison Park. Story no longer available. A story covering solar sails in general and the recent tests of L'Garde's 20-m square solar sail in the giant thermal-vacuum chamber at the NASA Glenn Plum Brook Station.

  • The Cosmos 1 solar sail mission is set for launch on Tuesday, June 21, 2005. Various updates are available on their website including videos by Louis Friedman and Bill Nye and two updates under the "What's New" section as well as the Cosmos 1 Weblog.

  • [http://www.planetary.org/solarsail/prelaunch_report1_20050523.html The Planetary Society: Solar Sail Update, May 23, 2005: Cosmos1 Ships in Preparation for June Launch: First Solar Sail Spacecraft Ready for Daring Flight. "Cosmos 1, the world's first solar sail spacecraft, has shipped in preparation for a launch window that opens on June 21, 2005, traveling from the test facility of Lavochkin Association in Moscow to Severomorsk, Russia. The innovative and first-of-its-kind solar sail, a project of The Planetary Society and Cosmos Studios, will launch atop a converted ICBM from a submerged Russian submarine. It will deploy in Earth orbit and attempt the first controlled flight of a solar sail."

  • [A 58 MB 12-minute video on the Columbus 500 Space Sail Cup has been made available by one of the creators, Greg Granville. The video shows animations of several of the solar sail designs intended to compete in the the Columbus 500 Space Sail Cup, as well as introduction to solar sailing. Also includes a news segment from NBC on the Znamya space mirror and solar sailing.

I have also placed a link to the video in Web Links#Documents.

  • <a href="http://planetary.org/solarsail/update_20050209.html">The Planetary Society: Solar Sail Update, February 9, 2005: A Pre-Launch Review.</a> All flight components have been delivered and tested, and a full mission sequence has been simulated with the flight computer. Some necessary corrections and fixes were done as a result of the testing. After reviewing the progress, the estimated launch period has slipped to some time in April, rather than March 1st to April 5th.

"Analysis of the radio tracking data from the Pioneer 10/11 spacecraft at distances between 20 - 70 AU from the Sun has consistently indicated the presence of an anomalous, small Doppler frequency drift. The drift can be interpreted as being due to a constant acceleration of a_P = (8.74 \pm 1.33) x 10^{-8} cm/s^2 directed towards the Sun. Although it is suspected that there is a systematic origin to the effect, none has been found. As a result, the nature of this anomaly has become of growing interest. We have developed a concept for a deep-space mission that would reveal the origin of the discovered anomaly. A number of critical requirements and design considerations for such a mission are outlined and addressed. In particular we explore the use of a solar sail as a means to reach a great distance from the Sun in a short period of time."

Thus, a mission similar to the Interstellar Probe might consider retaining its sail beyond the orbit of Jupiter to measure the matter density in deep space. Such an experiment would a yield an independent, new type of measurement of the interplanetary medium and should be pursued."
