[Artist Concept] When it comes to a spacecraft enduring the extremely hot and fast journey from deep space back to Earth, NASA’s #Orion can withstand the heat. Engineers developing Orion’s thermal protection system have been improving the spacecraft’s heat shield design and manufacturing process since the vehicle successfully traveled to space for the first time last year. They are now enhancing the overall system in advance of the spacecraft’s next mission – a flight that will put Orion through the harshest set of conditions yet. Orion’s thermal protection system is one of the most critical parts of the spacecraft and is responsible for protecting it and the future astronauts it will carry home from deep space destinations. It consists of the spacecraft’s main heat shield that faces into the atmosphere on reentry to slow the spaceship down and also the grid of tiles known as the back shell. During Orion’s next mission atop the agency’s Space Launch System (#SLS) rocket, called Explo...
