Question

1. ccc communicate information identify a spacecraft operated by human beings and describe how it helped add to our knowledge of space.

Explanation:

A suitable spacecraft is the Apollo 11. It was the first manned mission to land on the Moon. By landing astronauts (Neil Armstrong, Buzz Aldrin) on the lunar surface, it provided direct evidence of the Moon's composition (e.g., samples of lunar rock were collected, showing it has similar elements to Earth's crust but different mineralogy), helped us understand the Moon's formation (supporting the giant - impact hypothesis as lunar rocks had ages and isotopic ratios consistent with this theory), and also gave insights into the space environment (like the effects of long - duration spaceflight on human physiology and the nature of the lunar exosphere).

Answer:

One example of a spacecraft operated by human beings is Apollo 11. Apollo 11 was the first manned mission to land on the Moon. When astronauts Neil Armstrong and Buzz Aldrin walked on the lunar surface, they collected lunar rock samples. These samples helped scientists understand the Moon's composition (e.g., it has minerals like plagioclase feldspar, pyroxene) and age (lunar rocks are around 4.5 billion years old, similar to Earth's formation age), which supported the giant - impact hypothesis for the Moon's origin. Also, the mission provided data on the lunar environment (e.g., the lack of a significant atmosphere, the nature of lunar dust) and the effects of spaceflight on human health (e.g., how the human body responds to weightlessness and radiation during long - duration missions), thus greatly expanding our knowledge of space.
