LightSail 2 was a fully functional spacecraft intended to demonstrate true solar sailing [6] and incorporated the lessons learned from LightSail 1. LightSail is a follow-on project to Cosmos 1 — a solar-sail spacecraft designed by The Planetary Society in the early 2000s, which was destroyed during a launch failure in 2005.
A phased array of ground-based lasers would then focus a light beam on the sails of these spacecraft to accelerate them one by one to the target speed within 10 minutes, with an average acceleration on the order of 100 km/s 2 (10,000 ɡ), and an illumination energy on the order of 1 TJ delivered to each sail. A preliminary sail model is ...
IKAROS, the first space-probe with a solar sail in flight (artist's depiction), featuring a typical square sail configuration of almost 200 m 2. Solar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces.

LightSail 2 with deployed solar sail. Project Forward was launched in 2011 with the purpose of exploring beamed energy propulsion. The project aims to analyze and assess past beamed-powered concepts, describe the construction of sail designs, and provide a starsail system concept. Challenges include lossy divergence of the beam as well as sail ...
A laser-pushed lightsail is a thin reflective sail similar to a solar sail, in which the sail is being pushed by a laser, rather than the sun.The advantage of lightsail propulsion is that the vehicle does not carry either the energy source or the reaction mass for propulsion, and hence the limitations of the Tsiolkovsky rocket equation to achieving high velocities are avoided.
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. [1] It consists of the launch year, a three-digit incrementing launch number of that year [n 1] and up to a three-letter code representing the sequential identifier of a piece in a launch.
Some wives prefer more material tokens of appreciation (a friend on marriage #2 just received a Birkin bag). But after 27 years of marriage, I crave small, constant signs that prove beyond a doubt ...
