Asaph Hall discovered Deimos on 12 August 1877 at about 07:48 UTC and Phobos on 18 August 1877, at the US Naval Observatory (the Old Naval Observatory in Foggy Bottom) in Washington, D.C., at about 09:14 GMT (contemporary sources, using the pre-1925 astronomical convention that began the day at noon, [16] give the time of discovery as 11 August ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Phobos (/ ˈ f oʊ b ə s /; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.

The Living Interplanetary Flight Experiment [2] (LIFE or Phobos LIFE [3]) was an interplanetary mission developed by the Planetary Society.It consisted of sending selected microorganisms on a three-year interplanetary round-trip in a small capsule aboard the Russian Fobos-Grunt spacecraft in 2011, which was a failed sample-return mission to the Martian moon Phobos.

If Phobos has been orbiting for 4.3 Ga (billion years) then Stickney formed 4.2 Ga ago, but if Phobos has only been orbiting for 3.5 Ga then it formed 2.6 Ga ago. [4] The impact created a large amount of ejecta which escaped Phobos' gravity and entered into orbit around Mars for a period not exceeding 1000 years, some of this material then ...
Indigenous people lived in what is now Texas more than 10,000 years ago, as evidenced by the discovery of the remains of prehistoric Leanderthal Lady.In 1519, the arrival of the first Spanish conquistadors in the region of North America now known as Texas found the region occupied by numerous Native American tribes.
