Notes for SpaceX 2023 summary by Elon Musk
- Falcon
- Most launches in a single year: 96, more than Soviet Soyuz 63 times.
- Heavy Falcon: 5 times, more than Saturn-V
- Starlink tasks: 2/3 of all tasks
- Falcon 9: 19 repeated launches
- 260 landings of boosters in the last 8 years
- Fairing recovery: 300s times
- Mass to orbit
- 1200 tons in 2023, 80% of the world, 90% expected in 2024.
- Only 20% of the mass in Earth orbit can reach Mars. About one million tons of goods should be sent to Mars in order to be self-sustainable.
- Dragon
- Have run for 1300 days in orbit
- 43 total successful launches
- 39 visits to ISS
- 22 reflights
- sent 42 humans to space and taken back
- Two towers in Florida
- Walk in space in 2024
- Starlink
- Enable people in remote places to learn
- Improve the quality of people’s lives
- V2 minis: next generation Starlink satellite
- Increase data rate from 88 TBps to 165 TBps
- Target: delay below 20 ms
- Argon-Hall thruster
- In-space laser
- 9000 active space lasers
- Each laser link has 100 Gbps transfer rate
- Direct link to cell
- 7 Mbps
- Good for text messages
- Suitable for remote regions, save people’s lives
-
Starship
- Thrust: currently is more than 2 times than Saturn V. The target is more than 20 million pounds, while Saturn V is 7.5 million pounds.
- Earth-to-earth transportation
- Upgrades between 1st and 2nd launch
- Launch pad: large water pressure
- Will build 2nd tower
- Migrate hydraulic to electric actuation of engines
- Almost everything has been upgraded from the 1st to 2nd launch, thousands of upgrades
- Hot staging achieved within 3 to 4 months
- If there were actual load, there would have been no oxygen venting and Starship would have go into orbit.
- 3rd launch
- Accelerate build and test: time is more expensive than hardware
- Becomes taller: 140 or 150 m
- Target
- Enter orbit and de-orbit
- Propellant transfer between header and main tanks at a tipping point
- Mass to orbit: 150 tons, while Falcon Heavy is 64 tons.
- On orbit refilling at the end of 2024 or early 2025
- Starlink deploy at the end of 2024
- NASA human landing system, Artemis program. Land on moon and build moon base
