The rocket is capable of hauling payloads of up to 23,000 kilograms to low Earth orbit thanks to its 9 massive Merlin engines (first stage). In true Elon Musk fashion, horsepower is exactly what we get. The lofty credentials and heavy workload mean that this thing has to be packing some serious horsepower. rockets, and the latest version, the Block 5, is regarded as the most advanced launch vehicle on Earth. The Falcon 9 has the most launches among all (currently operational) U.S. SpaceX has been contracted by NASA to use the vehicle to ferry astronauts to the ISS since 2008. The Falcon 9 is a high-performance medium-lift launch vehicle that is designed (and certified) to transport humans and cargo to the International Space Station. How much pollution does a Falcon 9 produce? We take a closer look at the Falcon 9’s by-products and how much damage they are capable of wreaking on the environment. The production of the liquid oxygen leads to a by-product of carbon dioxide while the burning of RP-1 also deposits soot into the atmosphere. The launch vehicle makes use of a liquid oxygen and Rocket Propellant 1 (RP-1) fuel blend. The Falcon 9 produces 1,115 tonnes of carbon per launch. However, the environmental impact of this craft is yet to be explored fully. The rocket’s achievements and missions have been well documented and lauded. The two-stage launch vehicle is Elon Musk’s pride and joy, and it is the latest in a line stretching back to 2006. SpaceX hopes to address this problem with its Starship vehicle by making the entire vehicle reusable, with both the Super Heavy rocket and Starship upper stage returning to Earth for reuse.SpaceX’s Falcon 9 is an engineering marvel that is steadily inching its way to iconic status. Today, they're a big contributor to the problem of orbital debris, so there is pressure on rocket companies to "dispose" of their second stages, either by deorbiting them or sending them into heliocentric orbits. Historically, when rockets deployed their payloads at higher orbits, these spent second stages were often just left in space for decades. There were no immediate reports of any injuries. The second stage of Falcon 9 burning up upon re-entry above my home in the Puget Sound.ĭid any pieces make it to the ground? It's possible that some of the more dense components of the rocket, such as pieces of the Merlin engine or composite overwrap pressure vessels, withstood re-entry and landed on the ground in the Rockies. It is likely that the second stage completely broke apart over the Rocky Mountains near the United States and Canadian border. This was, however, simply the Falcon 9 rocket's second stage-which weighs about four metric tons unfueled-breaking apart in the atmosphere and burning up. Videos shared on various social media networks showed what appeared to be an invasion by an alien armada. On Thursday night, three weeks after launching, this second stage re-entered the thicker part of Earth's atmosphere and, in doing so over populated areas, provided some spectacular views for the Portland and Washington state region. This high above the Earth, it was still susceptible to drag from the thin wisps of our planet's upper atmosphere. In this case, the Falcon 9 upper stage still comes back because when it released the Starlink satellites, the vehicle was orbiting Earth at an average altitude of about 250 km. So the propellant was vented into space, and the second stage was set to make a more uncontrolled re-entry into the atmosphere. However, there was not enough propellant after this launch to ignite the Merlin engine and complete the burn. just caught this flying over my home in SW Portland. Typically, within an orbit or two of launching, the Falcon 9 rocket's Merlin vacuum engine will relight and nudge the second stage downward so that it harmlessly re-enters Earth's atmosphere into the Pacific Ocean. The entire mission was nominal, except for a problem with the rocket's second stage. It was the first of four such missions flown this month by SpaceX. A little more than three weeks ago, a Falcon 9 rocket launched from Florida's Kennedy Space Center carrying a payload of 60 Starlink satellites into low Earth orbit. ![]()
