Spotting NASA's Solar Sail: An Exciting Opportunity

NASA's Advanced Composite Solar Sail System has fully deployed its reflective sail in orbit. This remarkable advance allows stargazers worldwide to spot the spacecraft in the night sky.

Stargazers can participate in NASA's #SpotTheSail campaign. Utilizing the free NASA app, available for both iOS and Android, users can discover when the solar sail will be visible in their area. The app has a location-specific schedule for sighting opportunities and features an augmented reality tool. This tool helps users pinpoint the spacecraft's position in real-time.

To spot the solar sail, follow these steps:

1. Install the NASA app on your iOS or Android device.

2. Open the app and tap the "Featured" tab on the bottom navigation bar.

3. Select the Advanced Composite Solar Sail System mission from the featured missions list.

4. Tap the "Sightings" tab at the bottom to see upcoming sighting opportunities for your location.

5. If you have an iOS device, use the "Sky View" link for augmented reality guidance during your sighting.

The Technology Behind the Sail

NASA’s Advanced Composite Solar Sail System tests innovative technology in low Earth orbit. This includes a composite boom system supporting a four-piece sail. Unlike solar panels, solar sails harness sunlight, allowing small spacecraft to propel themselves without traditional rocket fuel. This technology can reduce costs for deep space missions and broaden access to space exploration.
