Per capita, a lot. In absolute terms, effectively zero.

Do you know roughly how many "car-hours" this flight would be in terms of green house emissions?

About 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-...

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.

It is a great idea and supporting a good cause! However, does it sound like you have to open a store with them to be eligible?

No, that's one of several options to earn entries. You can just donate to St. Jude.

I like how they say "no earlier than the forth quarter" in their announcement. Though it may not inspire confidence in a deliverable date, I might start trying to use the turn of phrase at my work.

Non-US residents are out of luck for this one, unfortunately. Otherwise, great initiative!

Also: "Participation in the Spaceflight is limited to individuals under six feet and six inches (6’6") in natural height and under two hundred fifty (250) pounds in natural body weight."

"The Inspiration4 crew will receive commercial astronaut training by SpaceX on the Falcon 9 launch vehicle and Dragon spacecraft, orbital mechanics, operating in microgravity, zero gravity, and other forms of stress testing. They will go through emergency preparedness training, spacesuit and spacecraft ingress and egress exercises, as well as partial and full mission simulations"

I would give my

looks at limbs, then looks around

... PS5 ...

to be one of the chosen astronauts.

Not 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-fl...

Yea that is surprisingly low, if accurate.

haha, also, refuse to use any time increment smaller than quarters. "I need to go use the restroom, but I'll be back this quarter."

It would be some next-level-up trolling to send up some Americans with Taiwanese and Hong Kong ancestry, although NASA already has form in this regard with Taylor Wang (ROC-born) and I note Iranian-born American Anousheh Ansari self-funded her way up too.

They should just send up Tom Hanks, some volunteers, and a lot of cameras.

I 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.
