India launches space mission to the sun a week after moon landing
(www.theguardian.com)
This is a most excellent place for technology news and articles.
Even though I couldn't find any connection between a space mission to sun and casteism, I could assure you friend the latter is much difficult to solve. That's why countries still struggle with casteism or racism or sexism or some other evil-ism, but we shouldn't let it hold us back from the technical and scientific advancements. In fact one could argue building a science oriented society is the way to eradicate these issues.
Yeah, I love it when people act like America doesn't have a fucking caste system. As though there weren't millions of Americans who voted for a rich guy who planned to build a wall to keep the "illegals" out of the country. And there wasn't a massive lobbyist effort by multi-billion dollar companies and oligarchs to kill unemployment benefits in order to push people back into shitty service jobs that pay peanuts.
