The reintroduction, carried out by the ‘San Diego Zoo Wildlife Alliance’ and its partners, is…
When humans leave Earth, even something as basic as knowing which way is up can become confusing. That made fish surprisingly useful subjects for space research. In 1973, Nasa sent two mummichogs and 50 eggs aboard Skylab 3, giving scientists a chance to watch both adult fish and young that developed entirely in orbit. Soon…

India also wants to build a new reusable rocket (representative image) For decades, launching a rocket into space followed a remarkably simple pattern: build it, launch it, use it once and throw most of it away.That model worked, but it was expensive.Now, the world’s space industry is trying to change the equation. Instead of watching…
