🚀 What Is Falcon 9?
Designed and built by SpaceX, Falcon 9 is the world’s first orbital-class reusable rocket, dramatically reducing launch costs by re‑flighting the first stage .
It stands about 70 m tall and uses nine Merlin 1D engines on the first stage, plus a single vacuum-optimized engine on the second stage .
Key achievements:
First flight: June 4, 2010.
First crewed orbital launch: May 2020, ferrying NASA astronauts aboard Crew Dragon .
As of mid‑2025, over 493 flights with only two in‑flight failures, making it America’s most flown orbital rocket .

🔁 Reusability & Landing
The booster returns either to an ocean‑based droneship (e.g. Of Course I Still Love You, Just Read the Instructions) or to land at launch sites .
Most boosters are now Block 5 variants, certified for at least ten flights with minimal refurbishment .

🛰️ Missions & Payloads
Most common mission: deploying Starlink internet satellites. Recent launches:
June 13 – delivered 23 Starlink V2 Mini satellites .
June 16 & 17 – batches of 26 and 28 Starlinks .
June 25 – launched 27 Starlinks and a crewed Dragon (Axiom‑4) to the ISS .
Also serves government, commercial, national security (e.g. NRO classified payloads) .

🔍 In Summary
Falcon 9: A workhorse rocket enabling frequent, reliable, and cost‑efficient access to space.
Reused dozens of times via booster recovery.
Supports Starlink constellations, ISS crew and cargo missions, rideshare for smaller satellites and even classified gov payloads.
As of July 2025, it's the most-flown orbital rocket in U.S. history, underpinning the modern era of spaceflight.
