A Pluto orbiter/lander/sample return mission was proposed in 2003. The plan included a twelve-year trip from Earth to Pluto, mapping from orbit, multiple landings, a warm water probe, and possible in situ propellant production for another twelve-year trip back to Earth with samples. Power and propulsion would come from the bimodal MITEE nuclear ...
Pluto (bottom left) compared in size to the Earth and the Moon. Pluto's diameter is 2 376.6 ± 3.2 km [5] and its mass is (1.303 ± 0.003) × 10 22 kg, 17.7% that of the Moon (0.22% that of Earth). [125] Its surface area is 1.774 443 × 10 7 km 2, or just slightly bigger than Russia or Antarctica (particularly including the Antarctic sea ice ...

Held the record for fastest human-made object at the time and the most distant one until Voyager 1 overtook in 1998. Closest approach towards Jupiter was at 02:25 UTC on 4 December 1973. Flew by Callisto, Ganymede, Europa and Io at long distances. Final signal received on 23 January 2003, 12 billion km (80 AU; 7.5 billion mi) from Earth. [5] 2
There’s also round-trip light time—that’s how long it takes a command to go from Earth to the spacecraft and back. In order to receive data on Earth, you have to command the spacecraft to start sending it 4.5 hours earlier. Likewise, if you want to send something, you have to send it to a point the spacecraft is going to be in 4.5 hours.
Clyde William Tombaugh (/ ˈ t ɒ m b aʊ /; February 4, 1906 – January 17, 1997) was an American astronomer.He discovered Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt.
For the first time since 2022, a total lunar eclipse will cause the moon to turn red as it passes through the Earth's shadow. Unlike a total solar eclipse that is visible from only a small area ...
