Lava on Io is among the many hottest issues within the Photo voltaic System. Volcanoes just like the one pictured above in Io’s Tvashtar Catena area spew lava onto the moon’s floor that reaches searing temperatures. This earns Io a spot among the many hottest locations within the Photo voltaic System. Meet the opposite toasty worlds and their frigid counterparts in our information to a few of the most excessive temperatures on the market.
Magma or lava? What’s the distinction? When magma from the mantle breaks by the crust of a planet and reaches the floor, it turns into lava. However what’s a mantle, and what’s a crust? Get the complete breakdown of what planets are fabricated from, from terrestrial worlds like Earth to ice and gasoline giants and even planets past our personal Photo voltaic System.
NASA’s photo voltaic crusing spacecraft has launched. The Superior Composite Photo voltaic Sail System (ACS3) spacecraft launched into Earth orbit on April 23, starting a mission to check a photo voltaic sail spacecraft with booms fabricated from composite supplies. This mission builds on the legacy of The Planetary Society’s LightSail 2 mission, which demonstrated that small spacecraft like this could use photo voltaic sails for managed propulsion.
The Day of Motion is arising, and you may participate from house. Whereas Planetary Society members meet in Washington, D.C., on April 29 to talk with their representatives in Congress in regards to the worth of investing in area science and exploration, you’ll be able to echo those self same messages from house. Fill out our pledge kind to take at-home actions, and we’ll e mail you with directions and particular alternatives to e mail and make cellphone calls to your members of Congress.
