SpaceX's workhorse Falcon 9 rocket expected to reach major launch milestone in 2020

Hours after SpaceX launched its 240th new Starlink satellite into orbit, Elon Musk took to Twitter to cryptically reveal that the company’s workhorse Falcon 9 rocket could “reach triple digits this year” if everything goes according to plan.

Designed and built by SpaceX in the late 2000s, the Falcon 9 rocket launched for the first time in June 2010. Developed for the unfathomably low price of $300 million from clean-sheet design to first orbital launch, the original single-core Falcon 9 rocket – known as V1.0 – was about 48m (160 ft) tall, weighed 333 metric tons (735,000 lb) fully fueled, and was capable of launching almost 10.5 metric tons (23,000 lb) into low Earth orbit (LEO). Famously, when provided with Falcon 9’s basic specifications and characteristics, an independent NASA study estimated that the rocket’s development would have cost the agency anywhere from $1.7 billion to $4 billion to design and build.

NASA came to this conclusion in 2011, less than a year after Falcon 9’s first launch, and that the disconnect between the status quo held by NASA and the broader US spaceflight industry and what SpaceX tangibly achieved came to almost perfectly symbolize the rocket’s first six or so years of operations. Although SpaceX stumbled hard with two catastrophic rocket failures in June 2015 and September 2016, the company ultimately picked itself up, learned from those still-agonizing lessons, and has since shaped Falcon 9 into one of the most capable, reliable, reusable, and prolific launch vehicles ever flown. That latter characteristic – the sheer volume of launches Falcon 9 has come to represent – is what CEO Elon Musk was referring to earlier this week.
