Definition
The twenty-first launch of the Falcon 9 (Dec 21, 2015), which achieved the first-ever vertical landing of an orbital-class rocket booster back on land.
Why It Matters
The ORBCOMM mission was the “Moon Landing moment” for the 21st century. It proved that a rocket could go to space and come back to its launch pad, something every “expert” said was impossible or uneconomical. This mission is the literal foundation of the modern space economy—without this landing, Starlink, Starship, and the Mars mission would be impossible. it is the physical proof that “The Old Guard” was wrong and that the “First Principles” of reusability were right.
Core Concepts
- The Comeback: Marked SpaceX’s return to flight after the CRS-7 failure six months earlier.
- Full Thrust Debut: First flight of the Falcon 9 v1.2 using Propellant Densification and higher-thrust Merlin 1D engines.
- The Landing: After deploying 11 satellites, the first stage performed a boostback burn and successfully touched down at Landing Zone 1 (Cape Canaveral).
- The Sonic Boom: The reentering booster produced three building-shaking sonic booms that were initially mistaken for an explosion by the launch team.
