Apollo 13 is a 1995 American space docudrama film directed by Ron Howard and starring Tom Hanks, Kevin Bacon, Bill Paxton, Gary Sinise, and Ed Harris. The screenplay by William Broyles Jr. , and Al Reinert dramatizes the aborted 1970 Apollo 13 lunar mission and is an adaptation of the book Lost Moon: The Perilous Voyage of Apollo 13 by astronaut Jim Lovell and Jeffrey Kluger. The film depicts astronauts Lovell, Jack Swigert, and Fred Haise aboard Apollo 13 for America’s third Moon landing mission. En route, an on-board explosion deprives their spacecraft of most of its oxygen supply and electric power, forcing NASA’s flight controllers to abort the Moon landing, and turning the mission into a struggle to get the three men home safely.
The GRAIL mission was managed by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, for NASA's Science Mission Directorate in Washington. The mission was part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Alabama.
Water in its life-sustaining liquid phase exists beyond our own planet, both in our Solar System--and elsewhere. With oceans of water sloshing around on 71% of our own planet's surface, Earth still remains the only planet known to have stable bodies of liquid water. Liquid water is essential for all known life forms on Earth. The existence of water on the surface of Earth is the outcome of its atmospheric pressure and a stable orbit in our Sun;s circumstellar habitable zone. The habitable zone is that Goldilocks region, surrounding a star, where the temperature is not too hot, not too cold, but just right for life sustaining water to exist in its liquid phase. However, the origin of Earth's water still remains unknown.
GRAIL has also generated new maps showing lunar crustal thickness. These maps have managed to uncover still more large impact basins on the near-side hemisphere of Earth's Moon--revealing that there are fewer such basins on the far-side, which is the side that is always turned away from Earth. This observation begs the question: How could this be if both hemispheres were on the receiving end of the same number of crashing, impacting, crater-excavating projectiles? According to GRAIL data, the answer to this riddle is that most of the volcanic eruptions on Earth's Moon occurred on its near-side hemisphere.
