Draco: ESA’s Quest to Decode Fiery Spacecraft Reentry
Unraveling the mystery of fiery reentry When a spacecraft returns to Earth, its final moments are a tense blend of heat, shock, and rapid transformation. For decades, scientists have watched from a distance as capsules and satellites torch through the upper atmosphere. But what happens in the exact, high-stakes microseconds of reentry remains a complex…

What happens in a spacecraft’s fiery reentry? ESA’s Draco mission
Unveiling the mystery of reentry Reentry is one of the most perilous phases of a space mission. As a spacecraft hurtles back from orbit, it encounters atmospheric air at temperatures that can melt metal and a speed that creates intense forces. The European Space Agency (ESA) is tackling a long-standing question: what exactly happens to…

What Draco Reveals About a Spacecraft’s Fiery Reentry
Introduction: A mission to shed light on a fiery finale When a spacecraft completes its mission, the descent back to Earth is often the least understood phase. The European Space Agency (ESA) has greenlit a bold project to study exactly what happens during the fiery end of a satellite’s life: the Destructive Reentry Assessment Container…

Time on Mars: Why Clocks Tick Differently on the Red Planet
Introduction: A Crucial Twist in Relativity on Mars Albert Einstein’s theory of relativity tells us that time isn’t a universal constant. The rate at which a clock ticks depends on gravity and motion. In practical terms, clocks tick more slowly in stronger gravity. Earth’s gravity is greater than Mars’s, so, all else being equal, time…
