SpaceX is preparing for an ambitious seventh test flight of its Starship megarocket, scheduled for Monday at 11 PM French time from Texas. This launch comes just two months after the sixth flight and introduces several innovative features and challenging objectives for the world's most powerful rocket.

The 123-meter-tall spacecraft, crucial for NASA's Artemis lunar program, will attempt multiple groundbreaking maneuvers during this test. For the first time, Starship will try to deploy a payload, consisting of ten mock Starlink satellites. These test units are designed to match the size and weight of next-generation Starlink satellites and will be released approximately seventeen minutes after liftoff, followed by a planned Raptor engine restart in space.

A key objective of this mission is the recovery of the Super Heavy first stage, standing at 71 meters tall. SpaceX aims to catch this reusable booster using robotic arms installed on the launch tower, a feat previously achieved during the fifth flight in October 2024 but unsuccessful in the November 2024 test. The company has indicated that this catching maneuver will only be attempted if conditions are optimal; otherwise, the booster will follow a trajectory for a soft landing in the Gulf of Mexico.

This flight will feature Starship version 2.0, incorporating significant upgrades. The forward fins on the 52-meter second stage have been reduced in size and repositioned closer to the nose, minimizing their exposure to heat during reentry. The thermal protection system features next-generation tiles and includes a backup layer to guard against potential tile damage or loss.

The propulsion system has undergone substantial improvements, including a 25% increase in fuel tank volume to enable longer missions. Technical enhancements include a more powerful flight computer, improved communications systems, high-capacity smart batteries, and over 30 onboard cameras for comprehensive performance monitoring.

A historic milestone for this flight is the reuse of a Raptor engine recovered from the fifth flight's booster. SpaceX is also conducting various experiments during this mission, particularly with the thermal shield. Several tiles have been deliberately removed to test vulnerable areas of the second stage, and multiple metallic tile options will be evaluated during atmospheric reentry.

To optimize the second stage recovery process, the spacecraft features various connection points for the launch tower's robotic arms. New radar sensors on these arms will be tested to improve distance measurements during the recovery attempt, representing crucial developments in SpaceX's pursuit of lunar and Martian missions with Starship.
