The Perseverance rover, NASA's wheeled explorer on Mars, has finally reached the rim of the Jezero Crater after a tough climb. On December 10, it paused at "Lookout Hill" to snap some amazing photos. These pictures show a mix of hills, ridges, scattered rocks, and hazy skies. The rover also looked b
NASA has a fresh plan for exploring Mars. They want to send smaller missions more often, with a focus on key scientific questions. These missions could cost between $100 million and $300 million each. The idea is to gather important information before humans ever set foot on the planet. The plan ha
Imagine you're in a spaceship far from Earth, and something goes wrong. Back in 1970, NASA folk had to fix a problem on the Apollo 13 journey using only what they had onboard. They couldn't just pop over to the store for spare parts! So, they used something called a "digital twin" for help. It's lik
The brain is a complex and sensitive organ, protected from the outside world by a series of barriers. These barriers, like the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCSFB), act like a fortress, letting only certain molecules in while keeping out potential threats—including
Eleven months after Ingenuity, a helicopter on Mars, made its last flight, engineers and scientists from NASA and a private company involved in its creation have found the probable cause of its crash. The problem? The chopper's sensors didn't see enough detail on Mars' smooth surface to figure out i
Imagine diving into space exploration without even leaving Earth. NASA has some thrilling plans up its sleeve, according to experts from the National Academies. They suggest focusing on two big projects. First, they want to figure out the magnetosphere, which is like an invisible shield around our p
NASA's Artemis program has hit a few bumps on the road to the moon. The plan to land astronauts there by 2026 has been pushed back to at least mid-2027. This isn't the first delay for the program, which has been adjusting its timeline as it prepares for its first crewed mission to the moon since the
Last week, a weird smell and droplets were found on the International Space Station (ISS) after opening a Russian supply ship. NASA astronaut Don Pettit compared the smell to spray paint. The crew quickly closed the hatch and checked the air. Luckily, the air quality returned to normal the next day.
Imagine going on a cosmic treasure hunt for planets similar to our own. NASA's New Worlds Observer (NWO) mission is an exciting step in this direction. This mission involves a 4-meter space telescope and a 50-meter starshade placed at a stable point between Earth and the Sun, known as L2. The goal?
Two NASA astronauts, Sunita Williams and Barry Wilmore, are living on the International Space Station longer than planned. They were supposed to stay for just eight days, but now it's been five months! People on Earth started to worry about their diet, especially Williams' appearance in photos. But
