[[NanoSail-D]] will test deployment of a 10 square-meter (100 square-foot) solar sail from a 10x10x30 cm [[wikipedia:CubeSat|CubeSat]]. The mission will also test deorbit using the sail, because atmospheric drag at the low altitude will likely dominate [[Solar Sailing 101#How Does Light Push a Solar Sail|light pressure]]. This is the backup spacecraft to the original [[NanoSail-D]], which was lost when the [http://www.spacex.com/F1-003.php Falcon-1] rocket it was on failed to reach orbit in 2008.

| − | The Second International Symposium on Solar Sailing ran from July 20-22, 2010, in Brooklyn, New York. The conference marked a remarkable step forward in the field of solar sailing. Several talks were given on Japan's [[IKAROS]] spacecraft, which was celebrated for demonstrating a solar sail spacecraft for the first time, and continues to sail on to Venus. Other talks described several small solar sail "nanosatellites" under development, which are planned to fly over the next few years. Other talks covered recent advances in understanding solar sail orbits, hybrid solar sail / solar electric missions, missions to test relativity, climate & weather observation, space weather, communications, alternative sail designs, and others. Refer to the [http://www.citytech.cuny.edu/isss2010/ conference website] for abstracts, program, proceedings, and (coming soon) the presentations.

| − | | + | |
| − | http://www.jaxa.jp/press/2010/07/20100723_ikaros_e.html
| + | |
| − | | + | |
| − | The [[IKAROS]] mission succeeded in steering using solar pressure. As the sail spins, liquid crystal devices along the edges change from reflective to non-reflective. Sunlight pushes harder on the reflective panels, so that one sail edge is pushed harder than the other, causing the sail to turn. Spacecraft like [[Mariner 10]] have used solar pressure to point them before.

| − | | + | |
| − | JAXA confirmed that the [[IKAROS]] spacecraft has generated the expected acceleration from the pressure of sunlight. This effect has been predicted for over a century since [[wikipedia:James Clerk Maxwell|James Clerk Maxwell's]] studies of electromagnetism. Every spacecraft flown since [[wikipedia:Sputnik|Sputnik]] has been affected, to varying degrees, by sunlight pushing on it. Several [[Category:Missions|missions]] have used solar pressure to their advantage. This is the first time a spacecraft specifically designed to propel itself on sunlight - a true solar sail - has done so. Congratulations to the [[IKAROS]] team on their accomplishment! I look forward to seeing what else [[IKAROS]] will accomplish in the days to come.

| − | | + | |
| − | JAXA's [[IKAROS]] project released images taken of the sail with the attitude control actuators active. The actuators consist of thin-film LCD panels along the edge of the sail which change reflectivity. While reflective, the panels reflect more sunlight and generate more thrust at the edge of the sail. While non-reflective, they generate less thrust. By phasing which side of the spinning sail is more or less reflective, they should be able to turn the sail. The images show the LCD panels alternating between reflective and non-reflective.

| − | [http://www.planetary.org/ The Planetary Society] announced the project LightSail to fly three solar sails of increasing size and complexity over the next several years. An anonymous donor provided funding for the missions, which will begin with LightSail-1, a 3-meter square sail deployed from a 10x10x30cm Cubesat. This is similar to NASA's [[NanoSail-D]]. LightSail-2 will be larger and have increased sailing ability out of Earth orbit. LightSail-3 is intended to sail to the sun-Earth L1 Lagrange point to demonstrate solar wind monitoring for geomagnetic storm forecasting. The Planetary Society previously attempted to test fly a solar sail in the [[Cosmos 1]] mission.
