The reality of sunlight-based sailing in space began in May 2010, and solar sail technology and science have continued to evolve rapidly through new space missions. Using the power of the Sun's light for regular travel propulsion will be the next major leap forward in our journey to other worlds. This book is the second edition of the fascinating explanation of solar sails, how they work and how they will be used in the exploration of space. Updated with 35% new material, this second edition includes three new chapters on missions operated by Japan and the US, as well as projects that are in progress. The remainder of the book describes the heritage of exploration in water-borne sailing ships and the evolution to space-vehicle propulsion; as well as nuclear, solar-electric, nuclear-electric and antimatter rocket devices. It also discusses various sail systems that may use either sunlight or solar wind, and the design, fabrication and steering challenges associated with solar sails. The first edition was met with overwhelmingly positive reviews, and deemed “a title that needs to be on your shelf if you’re seriously interested in the next step as we move beyond rocketry" (Centauri Dreams, September 2008). Written with a mixed approach, this book appeals to both the general public as well as those with a more scientifically technical background.
Solar sailing offers the possibility of low-cost long-distance missions, impossible for any other type of conventional spacecraft. The book provides a detailed account of solar sailing, at a high technical level but in a way accessible to the scientifically informed layman. Solar sail orbital dynamics and solar radiation pressure form the foundations of the book, but the engineering design of solar sails is also considered, along with potential mission applications. This book introduces the subject and at the same time provides a technical reference source.
This book presents the best contributions of the the Third International Symposium on Solar Sailing Glasgow, 11 – 13 June 2013. It is a rapid snap-shot of the state-of-the art of solar sail technology in 2013 across the globe, capturing flight programs, technology development programs and new technology and application concepts. The book contains contributions from all of the leading figures in the field, including NASA, JAXA, ESA & DLR as well as university and industry experts. It therefore provides a unique reference point for the solar sail technology. The book also includes key contributions from the prospective users of solar sail technology, which will allow the technology to be considered by the user in this unique context.
Louis Friedman, Executive Director of the Planetary Society, presents the first comprehensive look at the science and history behind solar sailing and other designs for space travel. Serious science readers and space buffs alike will be fascinated by designs for the square sail, disk sail, and the heliogyro (which features flexible sails many kilometers long). Friedman compares solar sailing to other proposed propulsion sytems such as ion drives and laser propulsion, and takes an insider's look at the million-dollar JPL project of the late '70s, which was the first attempt at a working model. Illustrated.
Elaborate on the concept of energy using this science inquiry card and lesson. Using vibrant, engaging images for science exploration allows all students to make connections and relate science concepts to new situations.
Solar sails are spacecrafts that use light propulsion to push their large sails to accelerate forward. Just like how sailboats use the wind to move across the ocean, solar sails use the pressure from light particles emitted from the Sun to push them forward. In space, absent of friction, this tiny pressure provides a constant acceleration to the sails and ultimately gain large values of velocity. Solar sails rely heavily on their massively thin sails to remain flat. Unfortunately, these sails are prone to deformations due to external forces encountered in space. If deformations occur, the sail will not receive the maximum amount of solar pressure. Changes in the shape of the sail can also cause the spacecraft to change trajectories. This paper will show the deformation of the sail due to celestial bodies. Solidworks will be used to model and analyze these forces using the finite element method. An analytic approach will be used to find the vibration mode shapes and frequencies for the sail. The vibration mode shapes and frequencies will then be compared with the values obtained from Solidworks to validate the use of the finite vi element method. Once verified, several loads such as solar pressure and gravitational forces from celestial bodies will be applied to the sail. Another test will be conducted to see the amount of deformation caused by changes in sail size. This thesis is focused completely on the analysis of the sails therefore, a simple quad-triangular solar sail configuration is used. The results show that gravitational forces caused by celestial bodies causes deformation to the sails depending on the orientation of the spacecraft. Increasing the sail size causes the deformations to grow exponentially.
