SpaceX market valuation surpasses Amazon after IPO rally

Starship Launch System:

• Composition: Fully reusable transportation system consisting of the Super Heavy booster (first stage) and the Starship spacecraft (upper stage).
• Propulsion: Both stages are powered by Raptor engines, which burn liquid methane (CH4) and liquid oxygen (LOX) propellants.
• Dimensions: When stacked, the Starship system has a height of 121.3 meters (398 ft) or 407 feet combined, and a diameter of 9 meters (30 ft).
• Thrust: The Super Heavy booster generates approximately 7,590 tons (18.1 million pounds) of thrust from 33 Raptor engines, while the Starship upper stage produces about 1,500 tons-force (3.5 million pounds) of thrust from 6 Raptor engines (3 sea-level and 3 vacuum-optimized).
• Payload Capacity: Designed to carry 100-150 metric tons (220,000-331,000 lb) to Low Earth Orbit (LEO), and 27 metric tons (60,000 lb) to Geostationary Transfer Orbit (GTO). With orbital refueling, it can transport over 150,000 kg to LEO, 21,000 kg to GTO, or 150,000 kg to Mars.
• Materials: The bodies of both stages are constructed from stainless steel.
• Heat Shield: The windward side of Starship is protected by a heat shield composed of 18,000 hexagonal black tiles, capable of withstanding temperatures up to 1,400 °C (2,600 °F).
• Control: Utilizes cold gas thrusters for unpowered flight in orbit and reaction wheels for agile attitude control.

Starlink Satellite Internet System:

• Architecture: A constellation of thousands of small satellites operating in Low Earth Orbit (LEO) at an approximate altitude of 550 km.
• Performance: Offers typical download speeds between 45 and 280 Mbps (with many users exceeding 100 Mbps) and upload speeds of 10-30 Mbps. Latency ranges from 25-60 ms on land.
• Satellite Design: Features a compact, flat-panel design to maximize launch efficiency on Falcon 9 rockets.
• Intersatellite Links: Each satellite is equipped with 3 optical space lasers (Optical Intersatellite Links or ISLs) capable of up to 200 Gbps, forming a global internet mesh.
• Antennas: Each satellite uses 5 advanced Ku-band phased array antennas and 3 dual-band (Ka-band and E-band) antennas for high-bandwidth connectivity.
• Propulsion: Employs efficient argon thrusters for orbit raising, maneuvering, and deorbiting, making Starlink the first argon-propelled spacecraft flown in space.
• Power System: Satellites feature a dual solar array and high-capacity battery.
• Navigation: Custom-built navigation sensors (star trackers) determine satellite location, altitude, and orientation for precise broadband throughput placement.
• User Hardware: Starlink Kits include a user terminal (dish), Wi-Fi router, power supply, and mounts, with various dish models available (Standard, Mini, Performance Gen 3, Enterprise).
