Key Takeaways
- Venus Mission by 2024 – ISRO chief in a national conference on Aerospace Quality and Reliability organised jointly by the Society for Aerospace Quality and Reliability, Thiruvananthapuram and Vikram Sarabhai Space Centre (VSSC).
- He also mentioned findings of Chandrayan – 1 and future launch of Chandrayan – 3.
About Venus
- Venus is the second planet from the Sun and is Earth’s closest planetary neighbour.
- It’s one of the four inner, terrestrial (or rocky) planets
- It is called Earth’s twin because it’s similar in size and density.
- It’s the hottest planet in our solar system, even though Mercury is closer to the Sun.
- It have a clockwise rotation which is opposite of the Earth’s rotation
- it has no moons and rings
- It was the first planet to be explored by a spacecraft – NASA’s Mariner 2 successfully flew by and scanned the cloud-covered world on Dec. 14, 1962.
| Note: Why is Venus So hot? Venus has a thick, toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect. |
