Ever wonder why NASA’s Mars rovers sometimes get stuck in the sand? Turns out, scientists may have been testing them wrong here on Earth! A new study says that just making the rover lighter for Mars gravity isn’t enough—the soil itself acts totally different out there. So, the next time a rover gets bogged down, it might be because our Earth tests were a bit too optimistic. Space travel: still not as easy as it looks! #Business #Industry #SpaceFail
