Question

how did satellites impact scientific understanding of space during the late 20th century?
satellites allowed astronauts to successfully navigate around the moon.
satellites allowed for more accurate predictions of solar flares.
satellites provided images from surrounding solar systems that confirmed the existence of other planets with water.
satellites provided high resolution photos that helped scientists research the origins of the universe.

Explanation:

• Option 1: Navigating around the moon was done by spacecraft (like Apollo missions) with onboard systems, not mainly by satellites for that specific navigation.
• Option 2: Satellites (e.g., solar observation satellites) can monitor the sun's activity, enabling more accurate predictions of solar flares by detecting precursor signs, which is a valid impact on space science understanding.
• Option 3: Satellites in the late 20th century did not have the capability to provide images from surrounding solar systems to confirm planets with water (exoplanet detection with such detail came later with more advanced telescopes and methods).
• Option 4: Researching the origins of the universe (cosmology) relies more on telescopes (like Hubble, but even Hubble's early work on cosmic origins was more about deep - field images of distant galaxies, and the high - resolution photos from satellites in the late 20th century were not the primary tool for this compared to solar flare prediction which is a more direct satellite - enabled space science advancement).

Answer:

B. Satellites allowed for more accurate predictions of solar flares.
