Hydranencephaly or hydrancephaly [1] is a condition in which the brain's cerebral hemispheres are absent to varying degrees and the remaining cranial cavity is filled with cerebrospinal fluid.[2]
Mission Objective. The mission objective of the Voyager Interstellar Mission (VIM) is to extend the NASA exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence, and possibly beyond.
When Voyager 1 blasted off from Earth on September 5, 1977, it was designed to last for five years. Today, on its 35th anniversary, the space probe continues to communicate with NASA as it approaches the heliopauseâthe boundary between our solar system and interstellar space. The farthest manmade object from Earth, Voyager 1 may keep exploring space for another 10 or 20 years before its power runs out. Meanwhile, check out these cool facts about the spacecraft and its mission. 1. Voyager 1 has an identical twin. In the early 1970s, the National Aeronautics and Space Administration (NASA) developed a mission called Voyager to make a âgrand tourâ of Jupiter and Saturnâand possibly Uranus and Neptune if all went well.
