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

The correct answer is B: Satellites allowed for more accurate predictions of solar flares.

Solar flares are sudden eruptions of coronal mass that happen in the sun's surface. Since these ejections release high energy particles that may interfere with radio communication and affect Earth's atmosphere it is important to study them and predict their cycles. For this reason, since the mid-1970s there have been several satellites and space observatories used in order to study and make accurate predictions of solar flares. Some of these satellites are:

-GOES (Geostationary Observational Environmental Satellite) system, the first satellite of this system was launched in 1974 by the NOAA from the US.

-YOHKOH, launched by the Japanese Institute of Space and Astronautical Science in 1991, it provided the first soft X-ray images of the sun.

-WIND, launched by NASA in 1994. It traces solar flares effects in the interplanetary medium.

-SOHO (Solar and Heliospheric Observatory), launched by the European Space Agency in 1995. It is one of the main sources of solar data.

Satellites allowed for more accurate predictions of solar flares.
