The Starship is being developed as a fully reusable launch vehicle, which is a significant advancement over the partially reusable Falcon Heavy. Despite this, the Falcon Heavy currently has several scheduled launches. It has secured contracts for various missions, including NASA and national security payloads. However, If Starship becomes operational and achieves its expected capabilities, it will likely lead to the eventual retirement of the Falcon Heavy.
Starship already had a significant year in 2023, marked by two full-stack flights and substantial changes to the launch pad, testing facilities, and production site. The first of these flights, conducted in April 2023, was a pivotal moment for SpaceX. The flight plan involved lifting off from SpaceX’s Starbase facility along the south Texas coast, conducting a powered flight to reach a transatmospheric Earth orbit, and then re-entering the atmosphere after roughly 1 hour and 17 minutes of flight. However, multiple Raptor engines failed during the flight, and the vehicle was lost shortly after lift-off.
The second test flight also faced challenges, including engine failures. Despite these setbacks, SpaceX’s aggressive testing and rapid development approach have been fundamental in advancing their Starship program.
Now, SpaceX is preparing for the highly anticipated third test flight of its Starship, expected to take place in February 2024.
The preparations for this upcoming launch are extensive, involving both the Starship vehicle and the infrastructure at the launch site. Significant upgrades have been made to the Orbital Tank Farm and the Orbital Launch Pad since the second flight. These upgrades include the installation of extra pumps and subcoolers, and a reconfiguration of the plumbing, allowing for separate subcoolers for the ship and booster. Additionally, SpaceX has been reinforcing the infrastructure around the launch pad to mitigate damage from sound waves produced during engine firings and static fire tests.
The company has been conducting a series of static fire tests to ensure the readiness of both the Super Heavy booster and the Starship upper stage, known as Ship 28.
A notable aspect of the third launch is the potential demonstration of in-space propellant transfer technology. This technology is crucial for the planned lunar missions under NASA’s Artemis program, where Starship would act as a lunar lander. The concept involves creating a propellant depot in low Earth orbit, which would be filled by a series of Starship tanker launches. This depot would then refuel the lunar lander Starship for its journey to the Moon. The number of tanker launches required for a lunar mission has been a topic of discussion, with estimates ranging from four to more than ten.
In addition to these flight tests, SpaceX also focused on improving its production and launch facilities. This included building a second Mega Bay to enhance vehicle stacking capabilities and upgrading the bridge cranes in Mega Bay 1 for easier booster lifting. The changes at the Sanchez site, like the ship engine install stand, streamlined the production process.
