According to Xinhua News Agency, an American space development company is working on the development of a mini greenhouse that can cultivate flowers on the moon and take the first step toward space greenhouses. Astronauts may one day be able to bid farewell to space foods such as dehydrated compressed foods and semi-liquid batter, and eat fresh vegetables away from the earth.
Agence France-Presse introduced on the 17th that the so-called "lunar oasis" is to send a small enclosed "greenhouse" to the surface of the moon. The "greenhouse" is shaped like a bell, and the exterior is protected by a triangular aluminum frame with a height of 46 cm to ensure that it can safely send the plants used for experiments to the moon and grow smoothly.
The Moon Expedition Limited, which stands out from the "Google Moon X Award," is responsible for sending missions. By then, the "greenhouse" will carry the seeds of Brassica into space. Such plants have a short flowering period, and it takes only 14 days from sowing to flowering in the earth, and it takes only one night to bloom on the moon.
First launched in 2012
Paragon officials said that according to the launch plan of the Moon Expedition, the “Lunar Oasis†test can only be launched in 2012.
“Although it is a long way to develop biomes on the Moon and even on Mars, it is important that we have already started to study it,†said Jan Bonnet, president of Paragon. “It takes time to research and develop a reliable and efficient system. In order to successfully cultivate biomes."
Pillow blocks are advanced applied in places with simple equipment and spare parts, such as agricultural machines, convey system or construction machines. One unit of pillow block consists of deep groove ball bearings with spherical outer rings closed in double sides and a housing made by gray cast iron or punches steel.
A Pillow Block Bearing (Plummer block) is a mounted bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft.
Pillow block bearings are generally self-lubricating.
Pillow block bearings are a form of mounted bearing used to provide load support for a rotating shaft axis. The bearing housing mounts to a surface parallel to the shaft axis. Selection of the appropriate bearings can be accomplished based on the shaft size and the radial and thrust load requirements. Pillow block bearings are designed to support a shaft: the mounting surface is on a parallel line with the axis of the shaft. Elongated bolt holes in the base or feet of the unit allow for some adjustment and easy mounting of the pillow block bearing.
