NASA’s Putting its Solar Sail Through its Paces

Those of you following the Advanced Composite Solar Sail System may have heard that its booms and sail are now deployed. It is receiving light pressure from the Sun to propel it through the Solar System. Like a test pilot in a new aircraft, NASA are now testing out just how it handles. Before deployment, the spacecraft was slowly tumbling and now the controllers will see if they can get it under control and under sail power. The reflectivity of the sail means its an easy spot in the night sky, just fire up the NASA app to find out where to look.

NASA’s New Solar Sail Has Launched and Will Soon Deploy

Solar Sails are an enigmatic and majestic way to travel across the gulf of space. Drawing an analogy to the sail ships of the past, they are one of the most efficient ways of propelling craft in space. On Tuesday a RocketLab Electron rocket launched NASA’s new Advanced Composite Solar Sail System. It aims to test the deployment of large solar sails in low-earth orbit and on Wednesday, NASA confirmed everything is looking good for sail deployment

Solar Sails Could Reach Mars in Just 26 Days

A recent study submitted to Acta Astronautica explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could dramatically reduce both the time and fuel required for such missions. This study comes while ongoing research into the use of solar sails is being conducted by a plethora of organizations along with the successful LightSail2 mission by The Planetary Society, and holds the potential to develop faster and more efficient propulsion systems for long-term space missions.

LightSail 2 is Still Solar Sailing, But it’s Getting Lower and Lower with Each Orbit

LightSail 2 captured this image on 25 November 2019. The top end of Australia’s Northern Territory is in the center of the image. North is approximately at the bottom of the image. The city of Darwin is beneath the clouds near the tip of the sail’s middle boom. The island of New Guinea can be seen to the left. A lens flare also appears in the left part of the image. The sail appears curved due to the spacecraft's 185-degree fisheye camera lens. The image has been color corrected and some of the distortion has been removed. Image Credit: The Planetary Society

LightSail 2 deployed it solar sail five months ago, and it’s still orbiting Earth. It’s a successful demonstration of the potential of solar sail spacecraft. Now the LightSail 2 team at The Planetary Society has released a paper outlining their findings from the mission so far.

The Light Sail is Working… It’s Working!

A beautiful sight! In this image, LightSail 2's solar sail is almost fully deployed on July 23rd. The fish-eye camera lens makes the sail appear warped. Image Credit: The Planetary Society

Good news from The Planetary Society: LightSail 2’s solar sail is functioning as intended. After launching on June 25th, then deploying its solar sail system on July 23rd, mission managers have been working with the solar sail to optimize they way LightSail 2 orients itself towards the Sun. Now The Planetary Society reports that the spacecraft has used its solar sail to raise its orbit.
