When We Left Earth: The NASA Missions (or NASA's Greatest Missions: When We Left Earth in the UK) is a 2008 Discovery Channel HD documentary miniseries consisting of six episodes documenting American human spaceflight from the first Mercury flights and the Gemini program, to the Apollo program and its Moon missions and landings, to the Space Shuttle missions and the construction of the ...
The JPL mission designers planned multiple launches in each block, to maximize the engineering experience and scientific value of the mission and to assure at least one successful flight. [14] Total research, development, launch, and support costs for the Ranger series of spacecraft (Rangers 1 through 9) was approximately $170 million. [15]
Galileo 's prime mission was a two-year study of the Jovian system, but on March 26, 1993, while it was en route, astronomers Carolyn S. Shoemaker, Eugene M. Shoemaker and David H. Levy discovered fragments of a comet orbiting Jupiter, the remains of a comet that had passed within Jupiter's Roche limit and had been torn apart by tidal forces.
The second moon that Earth has captured in its orbit this month is an asteroid called 2024 PT5. Mini-moons like this could be ideal targets for asteroid mining to send humans deeper into space .
Astronomers posed over the past decade that dark comets, or objects that resemble asteroids but move like comets, may exist. Now, scientists have found a total of 14 of them.
