The Planetary Society announced that it will launch a brand new solar sail ship in 2015. Its greatest feature is the use of light pressure power drive. It is a new driving force for future interplanetary flight. The solar sail ship that may launch in 2015 is named LightSail- A. It uses almost the same hardware equipment as LightSail-B. It is a solar sail ship developed under the LightSail-1 mission.
The newest SolarSail spacecraft of the LightSail series will be launched into orbit around 2015, and the solar sail ship will enter a new period of development in the next few years. At present, Japan is in a leading position in this field.
The solar sail ship will be one of the most promising space dynamics in this century, but the acceleration of light pressure drive is very slow
On July 9th, the Planetary Society announced that it will launch a brand new solar sail ship in 2015. Its greatest feature is the use of light pressure power drive. It is a novel driving force for future interplanetary flight. The solar sail ship that may be launched in 2015 will launch. Named LightSail-A, it uses almost the same hardware as LightSail-B, which is a solar sail ship developed under the LightSail-1 mission. The LightSail-B's orbit is not far away. It is mainly operated in low-earth orbit. It only needs solar radiation to drive the spacecraft forward. However, whether the solar sail ship can make a trip is still unknown because it will be used by SpaceX's "Hybrid Hunting." The Eagle rocket fired off, but the rocket is still not ready.
The LightSail-B spacecraft does not enter the orbit as a direct payload and it still requires the support of another spacecraft. This is the Prox-1 detector. This platform is a science and technology project of the Georgia Institute of Technology. When the Prox-1 probe When the device enters Earth orbit, LightSail-B will be released and then the solar sail will be deployed. According to the Planetary Association, we can even see the development of solar sails through professional observation tools. The solar sails on the LightSail-B spacecraft reach 344 square feet, about 32 square meters, which is obviously larger than some orbiting satellites. In fact, if the observation conditions are good, it is possible to photograph the spacecraft on the orbit.
Prior to the LightSail solar sail project, scientists also conducted a number of solar sail research projects, such as the launch of the "Cosmos-1" solar sail ship by Russia in 2005, which cost 4 million U.S. dollars. The spacecraft consists of eight huge ones. The polymer film is composed but it fails to enter the orbit. Japan JAXA also tested the solar sail ship in 2010. Currently, the United States, Japan, and Europe all have their own progress on the solar sail ship. The Planetary Society believes that the solar sail ship has great potential and can save a lot of space compared to the traditional spacecraft. Fuels and optical pressure-driven acceleration are slow and require a lot of time to increase speed, but scientists think this is a very economical exploration program. If there is enough time, it can complete the investigation in the solar system.
The cost of the LightSail solar sail ship is about US$4.5 million, but the launch date may be affected by the SpaceX launch vehicle. It is worth noting that the Japanese solar sail detector is currently at the forefront of technology and its solar sail ship has been developed. Interplanetary flight was completed, flying over Venus, and NASA's deployment of the NanoSail-D spacecraft in Earth orbit was also a validation project. At the same time, a project called Sunjammer was underway. It is expected that solar sail will be between 2015 and 2016. Spacecraft development peak.
Tool pouch is a small bag or pouch designed for carrying and storing hand tools. It is typically made of durable materials like canvas, leather, or nylon and may have multiple pockets or compartments for organizing different types of tools.
Tool pouches are commonly used by professionals such as carpenters, electricians, and plumbers who need quick and easy access to their tools while working. They are also useful for DIY enthusiasts and homeowners who need to keep their tools organized and easily accessible.
There are many different types of tool pouches available, ranging from basic pouches with a few pockets to more advanced models with specialized pockets for specific tools. Some tool pouches can be attached to a tool belt for hands-free carrying, while others are designed to be carried on their own using a shoulder strap or handle.
Overall, a tool pouch is a convenient and practical accessory for anyone who regularly uses hand tools and wants to keep them organized and accessible.
