🔥 $450 MILLION IN SOLAR PANELS. GONE. ON PURPOSE. HERE IS WHY. ☀️
Most people watching Artemis II splashdown will see Orion's parachutes and cheer.
They will not know that 34 minutes earlier, a $450 million piece of spacecraft was deliberately incinerated.
☀️ Step 1 — The Solar Arrays Power Everything:
Orion's four solar wings are part of the European Service Module (ESM), built by Airbus for ESA.
Each wing stretches 7 meters. Together, they span 19 meters and generate 11.2 kilowatts of electricity, enough to power two average homes.
They power the computers, life support, communications, navigation, thermal control, and all 33 engines.
✂️ Step 2 — Separation at 7:33 PM ET, April 10:
With Earth 400,000 feet below, 300+ explosive pyrotechnic bolts fire simultaneously.
The ESM, solar panels and all, physically detaches from the crew module in a controlled explosive event.
Two separate objects now fall toward Earth on different paths.
🔥 Step 3 — The ESM Has No Heat Shield:
Without Avcoat ablative shielding, the ESM cannot survive the heat of reentry.
The solar wings, the engines, the structure, all of it burns up completely over an uninhabited ocean zone.
It is not a malfunction. It is the plan.
🛡️ Step 4 — Crew Module Alone Survives:
The Orion capsule, protected by its 16.5-foot heat shield, the largest ablative shield ever built, absorbs 2,500°C.
Four parachutes slow it from 25,000 MPH to 325 MPH.
At 8:07 PM ET, Pacific Ocean. Mission complete.
Did you know the ESM was designed to burn up from the very beginning?
