- What is one of the Mars missions that is currently operating and write about the mission’s history, goals, and accomplishments to date.Which of the following planetary traits is well established? choose one of the following: a) Mercury has a similar compositon to that of our moon, in that they both have a substantial metal content. b) Venus rotates more rapidly than Earth, but in the opposite direction. c) Earth's atmosphere exhibits a slightly stronger greenhouse effect than that seen on Venus. d)Astronomers have precisely calculated the mass of Mercury thanks to artificial satellites sent from Earth.If the cloud layer of Venus is so thick, how is it possible for any sunlight to reach the surface planet the
- Mars has the largest volcanoes in the solar system. (T/F)Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?Eventually, space telescopes have shown that Venus is shrouded by a very dense atmosphere (see Figure 6). To pierce through the dense clouds and study its surface, astronomers had to use radio imaging (see Figure 7). Venus’ atmosphere is transparent to radio waves. Research and explain briefly how, through radio imaging, Venus’ surface could be reconstructed.
