The Daring LightSail 2 Spacecraft Is Being Sucked Into Fiery Doom

Jun 30, 2022

The Planetary Society’s LightSail 2 launched in June 2019 and unfurled its 344-square-foot (32-square-meter) solar sail a month later. Just two weeks after spreading its wings, LightSail 2 gained 2 miles (3.2 kilometers) of altitude, making this experiment a success. But for the past few months, LightSail 2 has been losing altitude at an increasing rate. It is now sailing at an average altitude of about 390 miles (627 km), down from about 446 miles (718 km) at the beginning of the mission, according to the Planetary Society. The scientists behind the mission are anticipating that LightSail 2 will reenter Earth’s atmosphere within the next several months, but they don’t have an exact date. During reentry, the spacecraft will be moving so quickly that it will create an energetic pressure wave ahead of it, causing the air around it to heat up and burn LightSail into a fiery shroud. Advertisement “Imagine throwing a rock compared to throwing a piece of paper. Atmospheric drag will stop the paper much faster than the rock.” Solar sails run on photons from the Sun, causing small bursts of momentum that propel the spacecraft; as the photons hit LightSail’s wings, the spacecraft is pushed further away from the Sun. If a spacecraft is able to surpass the drag from Earth’s atmosphere, it could potentially reach very high altitudes. Advertisement Throughout its mission, LightSail 2 has enjoyed some highs and lows (literally). The orbiter sometimes lost a few meters of altitude per day and sometimes gained a few meters. But after three years of sailing around the Earth, the experimental device began to experience a steep drop in altitude as the result of several factors. This graph shows LightSail’s average altitude with time (shown in blue). Illustration: The Planetary Society Advertisement As the spacecraft got lower, the atmospheric density increased very rapidly, resulting in atmospheric drag. LightSail smashed into atmospheric particles as it traveled at speeds reaching 20,000 miles per hour (32,000 km/hr), causing the spacecraft to slow down. “Our case is more extreme than most spacecraft because the area of our sail is very large compared to the mass of the spacecraft,” the Planetary Society wrote in a statement . “Imagine throwing a rock compared to throwing a piece of paper. Atmospheric drag will stop the paper much faster than the rock.” Ironically, the Sun also worked against LightSail 2. When the Sun is more active, it heats Earth’s upper atmosphere, causing it to expand into higher altitudes. At the start of the mission, the Sun was going through some downtime as part of its 11-year cycle, but our host star recently revved up its activity for its solar maximum period. This has caused the atmosphere to be denser at higher altitudes, even reaching the spacecraft, causing LightSail 2 to drag downwards. Advertisement The third factor leading to LightSail’s demise is more human than cosmic. The mission suffered communication glitches due to faulty equipment at the ground station. During times of communication drop-off, the team was unable to send data to the spacecraft, causing its sailing to suffer, albeit slightly. Although LightSail 2 will soon meet its fiery death, the spacecraft’s legacy will still live on. The orbiter has inspired several other missions, including NASA’s NEA Scout mission to a near-Earth asteroid (scheduled for launch in August), NASA’s Advanced Composite Solar Sail System to test out sail boom material in Earth orbit (scheduled for launch sometime mid-2022), and NASA’s Solar Cruiser  (scheduled for a 2025 launch). The era of the solar sail, it would seem, is quickly approaching. Advertisement
