Vedas are flooded with space topic and other such things. Vedas are filled with mantras where they do yagya and make som ras a kind of anti-aging juice, elixir etc.
The rishis are making somras and offering them to devas to come down from sky or other worlds. Devas then come to consume the somras and in return give various valuable resources to humans. From gold to technology etc.
Vedas clearly and in multiple mantras speak of Devas making Planet Earth habitable. However the biggest problem is they use common words for multiple things. For example they use word Indra for Sun, cow for planet. Top part in screenshot it talks about how sun gives light to all planets, holds them with gravitation. Then indra word is also used for devas who have duty to manage human life. Indra finds cow (planet) hiding in dark caves (dark space) and makes it habitable. Vedas give us idea how devas manage life in a solar system and rakshas or asuras trying to ruin life on a planet.
48 mantra in screenshot tells about people doing yagya and making somras for Indra. When offered to Indra he comes down with a sound of a bull. Word horse is used here for spacecraft, bull sound for the sound it generates. Various bright lights are also mentioned in the horse!. Do horses have lights?. While offering somras people could go to heaven as reward.
23 mantra - The Ashwini Kumars have 3 chakra rath which means some kind of craft or vimana. This vimana is invisible.
There are many references to such flying things, heaven, super sonic speed etc. I will continue in next articles.
