🕮 Spacecraft that was the First Spacecraft to Make a Soft Landing on the Moon

Luna 9 was a Soviet spacecraft that was the first spacecraft to make a soft landing on the Moon. It was launched on January 31, 1966, and landed on the lunar surface on February 3, 1966, in the Oceanus Procellarum region. The spacecraft was equipped with several scientific instruments, including cameras and a penetrometer to study the lunar soil.

After landing, Luna 9 transmitted the first close-up images of the lunar surface back to Earth, which provided scientists with valuable information about the Moon's topography and soil composition. The spacecraft also conducted experiments to measure radiation levels and study the properties of the lunar dust.

Luna 9 was a significant achievement in the history of space exploration, as it demonstrated that it was possible to land spacecraft on the Moon and transmit scientific data back to Earth.

Rotation Curve for a Spiral Galaxy is "Flat"

Question

What do we mean when we say that the rotation curve for a spiral galaxy is "flat"?

Answer

A) The amount of light emitted by stars at different distances is about the same throughout the galaxy.

 B) Gas clouds orbiting far from the galactic center have approximately the same orbital speed as gas clouds located further inward.

C) The disk of a spiral galaxy is quite flat rather than spherical like the halo.

D) All the galaxy's mass is concentrated in its flat, gaseous disk.
