SpaceX Prepares for Crucial Starship Test Flight
Thursday’s Launch to Push Development of Mammoth Vehicle
SpaceX is gearing up to launch the seventh test flight of its Starship rocket on Thursday, a critical step in the development of the massive vehicle. The company has a one-hour window, from 5 p.m. ET to 6 p.m. ET, to launch Starship from its private “Starbase” facility near Brownsville, Texas.
Satellite Deployment Test
On board the rocket will be 10 “Starlink simulators” in the payload bay, which will be deployed once in space. This test is crucial for SpaceX, as it needs Starship to deploy its upcoming generation of Starlink satellites. The simulators, made of unknown materials, will follow a similar trajectory to the rocket and are designed to burn up during reentry.
Rocket Capabilities
Assuming the launch goes according to plan, Starship will reach space and travel halfway around the Earth before reentering the atmosphere and splashing down in the Indian Ocean about an hour after liftoff. The rocket’s “Super Heavy” booster will return after separating from Starship and land on the arms of the company’s launch tower.
Starship’s Importance
Starship is vital to SpaceX’s plans, with its $350 billion valuation and dominant position in the space industry. The rocket is both the tallest and most powerful ever launched, standing 403 feet tall and 30 feet in diameter. SpaceX has flown the full Starship rocket system on six spaceflight tests since April 2023, at a steadily increasing cadence.
Super Heavy Booster
The Super Heavy booster, which stands 232 feet tall, is what begins the rocket’s journey to space. At its base are 33 Raptor engines, producing 16.7 million pounds of thrust – about double the thrust of NASA’s Space Launch System rocket.
Ship 33: A Second-Generation Starship
The Starship flying on this launch, tagged as Ship 33, represents a second-generation version of the vehicle, called “Block 2.” This vehicle includes significant upgrades, such as changes to the flaps on the vehicle’s nose, redesigns of its propulsion system, an enhanced flight computer, and a reinforced heat shield.
Fully Reusable and Critical to NASA’s Moon Program
The Starship system is designed to be fully reusable and aims to become a new method of flying cargo and people beyond Earth. The rocket is also critical to NASA’s plan to return astronauts to the moon, with SpaceX winning a multibillion-dollar contract to use Starship as a crewed lunar lander as part of NASA’s Artemis moon program.
