"We've launched more mass to orbit than *everyone else* did *every year* in history, unless you count the lovely Space Shuttle Orbiters by themselves.""What have you done today?"(Graphics by @planet4589: https://planet4589.org/space/stats/pay.html)
Falcon 9 launches 23 @Starlink satellites to orbit from Florida. We’ve now launched 80 times in 2023, delivering more than 1,000 metric tons to orbit
Falcon has delivered over 1000 tons to orbit this year, a world record
This is significantly more than any country has launched with their entire rocket fleet in a year. Second is peak Soviet Union at ~500 tons.For a present day comparison, the rest of the world has delivered ~250 tons to orbit so far this year, mostly by China.
Chart looks somewhat similar to my dV adjusted mass to orbit chart.The biggest dilemma was how to tally the shuttle, as counting the entire mass of the orbiter isn’t a fair representation IMHO.

Including the vehicle does not make sense IMHO.

Including the vehicle does not make sense IMHO.I would not count it if it wasn’t carrying people… but it is, so it’s also not fair to not count at least some of it.The compromise I came to for my method was to estimate how heavy an unmanned version of the shuttle would weigh and subtract the difference.The same will have to be done when a manned Starship flies too.

If they're just there to lower the landing gear neither they nor their life support should count at all.But mass to orbit will always be an imperfect metric. It's better to just accept that than try to refine it into a different, equally imperfect metric.

If they're just there to lower the landing gear neither they nor their life support should count at all.But mass to orbit will always be an imperfect metric. It's better to just accept that than try to refine it into a different, equally imperfect metric.Personally, if I were to determine 'total mass to orbit' launched by an organization, company, or country I would even include the mass of empty rocket stages that entered orbit - even if the stage was only in orbit for less than a couple of orbits.That means that I would include in the mass SpaceX has placed into orbit at least the dry mass of the more than 80 Falcon 9 second stages launched this year - even though most of them have since reentered Earth's atmosphere. That alone would account for 332t to orbit even without taking into account any remaining propellants.My definition also means that the space shuttles entire mass would be included, not just the mass needed to support the crew. In 1985 the Shuttle launched 9 times - accounting for more than 700t placed into orbit.Payload mass to orbit would not count any upper stages that reach orbit unless the useful payload is attached to them.

(11 pics for wiki explanation)Those numbers are delta v adjusted numbers. I feel like it’s explained in the thread, but maybe it isn’t.They are adjusted higher based on the rocket equation using a 320isp hypergolic rocket for orbit raising. e^(((deltav for delivered orbit) - (delta v for 185km LEO))/3136) x launch massIt’s the “least unfair” way I’ve found to tally orbit launch activity, because just counting raw tonnage is also unfair to launches that are delivering payloads to higher energies.

paper, led by Ariel Graykowski of the SETI Institute, and utilising the observations of citizen scientists, the amount of brightening of Dimorphos in the aftermath of the [DART] collision led to an estimate of the mass of the ejecta being 0.3–0.5 per cent of Dimorphos’ total mass.
And that by a single 610 kg probe launched from Earth by a F9
An F9 that launched in 2021, and a spacecraft impact which occurred in 2022.None of which would be countable in a tally of 2023 activities... even if it were reasonable to do so.
In 2022 and 2023 SpaceX launched a total of 157 times, which is slightly more than the 155 times ULA launched over its entire 17 year history.
