  • 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."

  • Space Services Inc.: October 11 2005: NOAA Awards Space Services Inc. a Contract to Assess Next Generation Solar Wind and Advanced Telecommunications Space Systems. "A team led by Space Services Inc. (SSI), a client of the Houston Technology Center, has been awarded a contract from the National Oceanic and Atmospheric Administration (NOAA) to assess commercial opportunities in developing and deploying next generation solar wind and telecommunications space systems. The SSI team, comprised of private companies, will examine cutting edge technologies to achieve detection of solar storms."
  • The Planetary Society: September 30 2005: The End of Cosmos 1, the Beginning of the Next Chapter"September 30, 2005: Cosmos 1 was-and is-a great effort, and one we are proud The Planetary Society tried to do. Our independent grassroots organization built and launched a spacecraft whose technology promises to one day open up interstellar travel. ... With our members' support, we are raising funds to build and fly another solar sail, and we are seeking new sponsors."
  • 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."

  • LA Weekly: Quark Soup: Space(F)light: Sailing the solar wind to the stars - Margaret Wertheim reports on the Planetary Society's Cosmos 1 solar sail project, and solar sailing in general. Editor's note: The author correctly explains that solar sails are driven by sunlight. But, there is a "solar wind" that is different from sunlight. It is composed of charged particles, whereas sunlight is photons.
  • Space.com: Reaching for Interstellar Flight - Leonard David reports on the difficulties of interstellar flight, and interviews Steven Howe of Hbar Technologies, who is developing the concept for one solution: the antimatter sail.

  • Ithaca Times: Solar Powered - Ithaca Times covers the Cosmos 1 solar sail mission, as well as a some solar sail history. Editor's note: While James Clerk Maxwell did first predict light pressure from his groundbreaking work on the electromagnetic wave nature of light, he did not discover photons. That was a discovery of quantum mechanics, which came much later.

  • E4Engineering: Setting sail on a solar mission - E4Engineering reports on the solar sail development effort of the European Space Agency and the German Aerospace Center. They intend to construct a 20x20 meter prototype that is intended to be launced within the next two years. It may be launched on a Volna submarine launched rocket, like the Cosmos 1 mission. The German Aerospace Center has already built a number of prototypes, including a 20x20 meter ground demonstration sail.

"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."

"A solar sail mission to deep space could determine the density of the interplanetary medium by measuring the drag force on the huge sail with radiometric navigational data. 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."

September 10th, 2003

  • Space.com: Fresh Spin on Solar Powered Asteroids - A new study in the September 11th 2003 journal Nature suggests that sunlight may have a significant and predictable effect on the spin of asteroids over long time periods. This is similar to the Yarkovsky effect which causes asteroids to drift off course, discovered in 1900 by a Russian engineer of the same name.

The document says on page 3, paragraph 2, that developing this technology will help NOAA and the USAF with their space weather and solar activity monitoring programs. NOAA and the USAF are developing GEOSTORMS just for this purpose.
  • The Znamya 2.5 space mirror experiment has been called off because the mirror became entangled with a communications antenna during deployment. Znamya 2.5 and the Progress cargo spaceraft which it is attached to be dropped into the atmosphere today. For further details, see the following articles:

  • I saw Mir and the [[Web Links#Past Missions | Znamya 2.5 space mirror] tonight at about 6:55 pm pacific standard time, about an hour after sunset from the countryside near Tacoma, Washington in the U.S. The two spacecraft rose from west by northwest and were separated by about 1 degree. The lead spacecraft was much brighter than any satellite I have ever seen, so I assume it was Znamya 2.5, even though the mirror did not fully deploy. About halfway across the sky, they winked out as they passed into Earth's shadow.
  • Znamya 2.5 space mirror failed to open today for its scheduled illumination test. The mirror snagged on an antenna of the Progress resupply spacecraft from which it was deploying. After two unsuccessful attempts to free the mirror and continue deploying it, mission controllers are considering ending the experiment.
