SpaceX record mass to orbit in 2023

[ZachF]

Here’s what my dV adjusted YTD totals look like:

1,721,637 kga 🌎 World

1,373,983 kga 🇺🇸 United States
1,325,443 kga 🇺🇸 SpaceX
180,032 kga 🇨🇳 China
97,539 kga 🇷🇺 Russia
40,473 kga 🇺🇸 ULA
36,383 kga 🇪🇺 Ariane & Vega
24,459 kga 🇮🇳 India
7,398 kga 🇯🇵 Japan
738 kga 🇳🇿 RocketLab
373 kga 🇰🇷 South Korea
369 kga 🇰🇵 North Korea
351 kga 🇮🇱 Israel
13 kga 🇮🇷 Iran

Is there a number for Northrop Grumman?

I think they only launched Antares once those year, so like ~8,000. (Not at computer)

1,721,637 kga  World

1,373,983 kga  United States
1,325,443 kga  SpaceX
180,032 kga  China
97,539 kga  Russia
40,473 kga  ULA
36,383 kga  Ariane & Vega
24,459 kga  India
7,398 kga  Japan
738 kga  RocketLab
373 kga  South Korea
369 kga  North Korea
351 kga  Israel
13 kga  Iran

While each orbit is calculated individually, here are what the adjustment factors look like for popular orbit insertions:

1.00x 185km x 27d LEO
1.06x 400km x 57d LEO-ISS
1.24x 500km SSO
2.22x GTO-1800
2.42x Molniya
2.44x GTO-1500
2.75x TLI
3.94x Direct GEO


So, Falcon 9 sending 17,250kg of Starlink satellites to 290km x 43d adjusts to 17,986.

Sending a 5,500kg payload to GTO-1800 adjusts to 12,210.

Ariane 5 sending 9,500kg to GTO-1500 adjusts to 23,180.

Delta IV Heavy sending 6,000 kg directly to GEO adjusts to 23,640.

Etc…

What are you counting extra in this year. "total launched 1,172,541 kg this year as per this table as of 2023-12-08" as per Wikipedia Starship was payload less. Crew Dragon mass included?? (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 mass

It’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.

OK it was kga not kg

SpaceX wants to be #1 but World beat it. It may seem impossible for SpaceX to beat World since everything SpaceX launches counts for World too but there's actually a solution to this problem: launch about 400,000 kga from Mars in a year, which counts for a different world. Mars surface to Mars transfer orbit is less delta vee than Earth surface to LEO so it'll take 1000-2000 tonnes of payload launched from Mars to get the adjusted mass needed to win. Fortunately SpaceX has plans to meet this goal. SpaceX's official mission is planetary redundancy but don't let that fool you - that's just a fig leaf to cover the true mission of beating "World" in Zach's ranking. It's an excellent cover - SpaceX would act similarly regardless of which is the true mission.

Zach will probably add The Solar System to the rankings once Mars launches happen, at which point SpaceX will need to go interstellar to beat The Solar System. Then they'll need to go intergalactic to beat The Milky Way. Eventually they'll need to look for new physics to beat The Universe!

I wasn't aware that it's a contest.

If it wasn't adjusted, an impactor to a small rubble pile asteroid would go a long way. Every rock that gets thrown up and doesn't fall back down counts as mass to orbit

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.

(1.33±0.30)×10⁹ kg * (0.3 to 0.5)% makes between 3,090 and 8,150 tonnes, and most of it to orbit
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.

And the credit would go to the spacecraft, not some LV that subcontracted for 610 kg of work.
But DART was just an example, and the context is hypothetical future launches, and the tally for future years.

[deltaV]

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.

[ZachF]

Some people seem to want to attribute all of SpaceX’s crazy 2023 to Starlink, but even if you factor out Starlink SpaceX still accounted for 46% of the world’s adjusted payload to orbit, and ~50% higher than second-place China.

From Elon’s all-hands a couple of days ago

[ZachF]

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.

SpaceX’s 2023 dv adjusted tonnage to orbit (1,417ta) is only slightly less than ULA’s lifetime figure (1,476ta).

Due to continued design improvements, this Falcon 9 carried its highest-ever payload of 17.5 tons of useful load to a useful orbit

This record could have been beaten by low-energy missions by an expendable Falcon or almost any type of Falcon Heavy. Yet this record was set by an ASDS Falcon 9. The types of Falcon and Falcon Heavy launches that could have beaten this record just haven't happened in the past few years.

BTW Ariane V flight VA-219 had a 20,293 kg payload, so Falcon 9 doesn't have the record for the most payload in one launch by a frequently used launcher family.
