- doctoboggan 6y agoDo you know roughly how many "car-hours" this flight would be in terms of green house emissions?
- ceejayoz 6y agoNot car-hours, but a Falcon 9 launch apparently has similar impact to a 777 crossing the Atlantic. Not nothing, but surprisingly little all things considered. https://www.treehugger.com/spacex-launch-puts-out-much-co-flying-people-across-atlantic-4857958 https://www.treehugger.com/spacex-launch-puts-out-much-co-fl...
- rhino369 6y agoYea that is surprisingly low, if accurate.
- ceejayoz 6y agoI mean, they're both 200 foot long tubes full of fuel that gets used up by the end of the flight. Only so much carbon you can fit into a set volume.
- hulahoof 6y agoAgreed, though without considering it as such if someone asked me to compare to an airliner I would have placed it between 10-100x the emissions, and would not have been surprised at more!
- bodhiandphysics 6y agoRemember 3/4 of the rocket is just the oxygen for combustion!
- Bedon292 6y agoDifference being the per person emissions. 4 people, vs upwards for 250. But still not nearly as bad as I thought it might be.
- ImprovedSilence 6y agoper capita, sure. Another way to think about it is this capsule is flying what, twice a year? One 777 will do 2 trips in 24 hrs, 365 days a year. Then add up the thousands of planes doing that a day. I'd be worried if we ALL had a reason (and the means) to take frivolous space flights. Which may come some day out of all this, who knows anymore!?!
- blhack 6y agoAbout 8.4 car seconds of fuel. Data: Us burns about 390,000,000 gallons of gas per day. SpaceX Falcon9 uses about 38,000 gallons of RP-1. 390000000/86400 = 4513 (gallons per second of fuel in the US). 38,000/4500 = 8.4 seconds. On the day this launches, it will represent about 0.0097% of the fuel used for that day in the US. There are about 280 cars in this photo: https://cimg0.ibsrv.net/ibimg/hgm/450x253-1/100/226/parking-lot_100226004.jpg https://cimg0.ibsrv.net/ibimg/hgm/450x253-1/100/226/parking-... If you printed out this image 40 times, you could delete ONE car from this image for one day. That's the difference that this launch will make.
- Bedon292 6y agoThis caused me to look up largest parking lots. You can fit approximately that many cars in the parking lots at Disney in Florida on any given day (11k+ spots). Though I don't know how full they actually get.
