Water on Mars any point in the year but would be ideal for solid carbon dioxide. The carbon dioxide melting in the warmer summer would yield liquid carbon dioxide which would then form the gullies. Even if gullies are carved by flowing water at the surface, the exact source of the water and the mechanisms behind its motion are not understood. The dry gullies are deep grooves etched into the slopes that are there year-round. There are many other features on Mars, and some of them change seasonally. In August 2011, NASA announced the discovery by undergraduate student Lujendra Ojha of current seasonal
Timeline of Mars Science Laboratory start studying the numerous bright veins embedded in the various layers of the ridge, in order to provide more details about the history and habitability of ancient Mars. On September 30, 2017, NASA reported radiation levels on the surface of the planet Mars were temporarily doubled, and were associated with an aurora 25-times brighter than any observed earlier, due to a massive, and unexpected, solar storm in the middle of the month. On October 17, 2017, NASA announced the testing of its systems on "Curiosity" in an attempt to better resume drilling. The drilling system had stopped working reliably in
