Why crashing into the sun is harder than escaping it
In short: While falling toward a massive star sounds like a simple descent, physics makes it an engineering nightmare. This video explains why slowing down enough to hit the sun requires more fuel and precision than fleeing our solar system entirely.
To reach the sun, spacecraft must fight against their own momentum. While missions like Voyager 1 and 2 used gravity assists to accelerate outward, a mission to the sun requires braking to cancel out Earth's orbital speed of 30 km/s. This process is complicated by the need to overcome escape velocity while simultaneously enduring extreme temperatures near the corona and intense solar radiation.
Even with advanced heat shields and multiple Venus flybys for gravity assists, the fuel required to decelerate a craft like the Parker Solar Probe—which travels at over 430,000 mph—to a crashing trajectory is currently beyond our technological capacity.
