PIX4639516: Permanent station project between Mars and the Earth - Artist view - Mars Cycler - Artist view - Artist view of the Mars Cycler project, a space station placed in cylindrical orbit between Mars and Earth; this project defended by Edwin Aldrin would make a permanent connection between the two planets. A Mars cycler is a permanently orbiting vehicle with a path that alternately brings it near Earth and Mars. Once a cycler has been accelerated into orbit it continues on its own momentum, going back and forth between the two planets, only requiring propellant for occasional course adjustments. A one-way trip between Earth and Mars involves six to eight months of space travel, therefore a large and well-equipped Mars cycler would offer space explorers, and possibly even space tourists, better accommodations for these long journeys. Smaller spacecraft would ferry travelers between the planets and the cycler. A Mars cycler is a permanently orbiting vehicle with a path that alternately brings it near Earth and Mars.

PIX4638680: Pneumatophores de Cypres balves - Courant d'Huchet - Landes - Bald Cypress knees - France - Located in the department of Les Landes, the Courant d'Huchet is a natural reserve since 1981. The Louisiana Bald Cypres (Taxodium distichum) was introduced there in the 18th century. This majestic tree can reach 40 m tall, but it is characterized mainly by its aerial roots (pneumatophores), up to one metre high. These roots come out of the earth to capture the oxygen that is missing in the marecagous soil. Taxodium distichum (Bald Cypress, or Swamp Cypress) is a species of conifer. Baldcypress growing in swamps have a peculiarity of growth called cypress knees. These are woody projections sent above the ground or water that are part of the root system.
