A. What is the primary mission of the Orbital Debris Observatory?
It is used as part of our national security to listen in on communication.
b. It is used to make three-dimensional models of the galaxies.
It locates spy satellites and decodes secret military languages.
d. It locates old satellites, lost equipment, and space-related garbage.
C.

The telescope is part of the ARES Division's Orbital Debris Program Office, whose mission is to determine the total amount of orbital debris and predict the risk it poses to spacecraft, including the International Space Station

Explanation:

The answer would be (D.) It locates old satellites, lost equipment, and space-related garbage.

Explanation: The prime objective is to monitor and assess the orbital debris environment by surveying orbiting objects at all orbital altitudes: LEO, medium Earth orbit, GTO, and GEO. The goal of the ODMSP was to limit the generation of new, long-lived debris by the control of debris released during normal operations, minimizing debris generated by accidental explosions, the selection of safe flight profile and operational configuration to minimize accidental collisions. There are millions of pieces of space junk flying in LEO. Most orbital debris comprises human-generated objects, such as pieces of space craft, tiny flecks of paint from a spacecraft, parts of rockets, satellites that are no longer working, or explosions of objects in orbit flying around in space at high speeds.

Have a great day!

world war i began in 1914, after the assassination of archduke franz ferdinand, and lasted until 1918. during the conflict, germany, austria-hungary, bulgaria and the ottoman empire (the central powers) fought against great britain, france, russia, italy, romania, japan and the united states (the allied powers). to new military technologies and the horrors of trench warfare, world war i saw unprecedented levels of carnage and destruction. by the time the war was over and the allied powers claimed victory, more than 16 million people—soldiers and civilians alike—were dead.

explanation:

the name of the theory is landmass theory.
