Summary

This episode of ‘Le Journal de la Starbase’ provides a comprehensive update on SpaceX’s activities at Boca Chica, Texas, as of late December 2021. The video covers the readiness of Starship 20 and Booster 4 for an orbital flight test, the addition of three Raptor 2 engines to future Starship versions, and the mysterious orange boxes on the Starship’s flanks. It details the construction progress of the orbital launch tower, including the cable and pulley system essential for catching the rocket, and the installation of a water deluge system. The video highlights the successful static fire test of the Raptor 2 engine, which achieved 245 tonnes of thrust and 321 bar chamber pressure, surpassing its predecessor. It also discusses Elon Musk’s announcement of a project to capture CO2 from the atmosphere and convert it into rocket fuel using the Sabatier reaction, which could be crucial for producing propellant on Mars. The video concludes with a discussion of the environmental implications and Musk’s motivations, inviting viewer opinions on whether these are genuine resolutions or mere public relations.
