    Fostering my sons love for space

    My son is 3 years old and I am blown away by the amount of information he has soaked up about space.

    His interest was sparked when learning about the dinosaurs, he thought they were cool and all but he was was enthralled by the asteroid that killed them more than anything.

    We got him a book about Earth and he memorized every factoid in the book. We got more and more books and he memeroized all the facts from those too.

    His interest has sparked my interest and I've put on documentaries like "secrets of the universe" and "the edge of all we know" for myself while he's playing or doing something and he will wander in and sit down and watch it with me. Glued to the TV like it's a cartoon.

    He can tell you all of the planets in our solar system. Which is closest and farthest from the sun, the smallest and largest, coldest and hottest. He knows Mars' moons and largest moons.
    He knows how a star is born and what happens when they die. He knows the different kinds of stars and knows the names of some of the larger ones. He knows about galaxy's and that when two spiral galaxy's collide they create an elliptical galaxy. Did I mention that he's 3?

    We just recently got a telescope but I'm still trying to learn it before I get him too excited about it. We also have a trip to a local observatory planned soon and are greatly looking forward to the upcoming eclipse. I am really hoping to take a family trip to Cherry Springs Pennsylvania this summer or fall but we will see about that one. I gotta sell the wife on that first.

    Any other suggestions to continue to foster this would be appreciated.

    I was intrigued in the science class talking about the solar system, but there are a few questions my teacher has trouble explaining them.

    What does “the sun shines directly between Tropic of Cancer and the Tropic of Capricorn” mean? The sun is a ball right? How does it shine on the other ball? I could only imagine the sun shines on the whole sphere of the earth that faces it, instead of part of it?

    And the distance between the sun and the earth is 92 million miles, comparing to the diameter of earth, which is 8k miles, the latter could be almost ignored. Then why the summer and winter are determined by the obliquity, instead of the earth’s location during revolution?

    I think I got it, upvoted all the replies. Thank you everyone!

    Soviet space program question

    I am trying to find some more information on an event in the Soviet space program: Some time in the 60s (I think) an engineer did a mistake or screwup of some kind and instead of being fired or sent to a gulag, he was awarded an engraved wrist watch from the man running the program for telling his superiors about the mistake.

    This is a very good example of how to create a safety-culture rather than a fear-culture and even in a country that strongly believed in the power of a good punishment.

    If anyone knows more about this, I would greatly appreciate the whole story or even a picture of the watch. The reason I am looking for this is that I want to use it in my "human factors" class, I work at a school that are training aircraft mechanics and this is a very important lesson in our line of work.

    President Biden Proposes 9.1% Increase in NASA Budget (Total $25.4B)

    EDIT: 9.1% Increase since the START OF BIDEN'S ADMINISTRATION. More context in comments by u/Seigneur-Inune.

    Taken from Biden's 2025 budget proposal:

    "The Budget requests $25.4 billion in discretionary budget authority for 2025, a 9.1-percent increase since the start of the Administration, to advance space exploration, improve understanding of the Earth and space, develop and test new aviation and space technologies, and to do this all with increased efficiency, including through the use of tools such as artificial intelligence."

    Suggestion/Question : Uranus's name

    Why won't the IAU change Uranus's name to Oranus (Oo-Ra-Noos)? It's the original Greek pronunciation, it will stop the confusion and jokes about the name and a lot of non English speaking countries are already using it. It's really a pain to teach about that planet and sure most people will find it difficult to adapt to the new pronunciation but once you change the spelling it will slowly become more and more universal.
