Throwing a shot put more than twenty kilometers was one thing, but when he threw another, the damn thing actually melted in midair and evaporated!
Once the reason was explained, everyone present was left stunned.
The return capsule of a crewed spacecraft could reach an astonishing speed of 15,000 meters per second when entering Earth's atmosphere.
That was not much different from the initial Mach 46 at which Chen Jue had thrown the Positioning Ball.
But after entering the atmosphere, the return capsule would experience intense friction with the air, and the temperature outside its hull could even exceed 8,000 degrees Celsius.
No metal or alloy on Earth could withstand that temperature.
To solve this deadly heat problem, the technical experts working on aerospace materials had finally come up with a solution. They coated the outside of the return capsule with a layer of honeycomb thermal insulation material, which carried away the immense heat generated by atmospheric friction through high-temperature ablation, melting, and sublimation, keeping the cabin at around 30 degrees Celsius throughout.
The Positioning Ball Chen Jue had thrown had no thermal insulation protecting it. Although it was made from the latest high-strength alloy developed at the base and could take quite a beating, it still could not withstand a surface temperature of 8,000°C. Making it five kilometers before evaporating completely was already quite an achievement.
"How about I borrow some insulation material from the Rocket R&D Department?"
"Wrapping the Positioning Ball in a layer of material wouldn't be difficult from a manufacturing standpoint. We could have it done in half a day," Zou Ying suggested.
"There's no need to go to all that trouble. Measuring my raw physical strength is enough."
"By my estimate, enhancing it with Martial Dao Gang Qi would amplify my power output by another
