Missile Heart (MISSILE (ミサイル) HEART (ハート) Misairu Hāto) is the two hundred and third chapter of the Dr. Stone manga.


The chapter begins with the Kingdom of Science obtaining fluorite in Barcelona, then making use of its low refractive index to make a better telescope. Kaseki shows off their model rocket, ready to test Xeno's jet engine. In order to calculate the trajectories they'll need, Ryusui says they'll be going to India and founding Math City.

The problem is the new Perseus goes through fuel faster than expected, so going the full route around the Cape of Good Hope will mean waiting for months before they can safely make the journey. Chrome suggests they make their way through the Suez Canal, however there's a risk it's blocked and they'll be left stranded. To avoid the risk of not being able to turn around in the canal, they use their new telescope and a hot air balloon to scan the route.

Chelsea makes a map of the area, only to discover there's a small dam 20 km into the canal, blocking the way. Senku decides that it would be a great opportunity to test their rocket, by filling it with dynamite and firing it directly into the dam to blow a path through.
