"Elon Musk's SpaceX gears up for major upgrades and tests ahead of next Starship launch."

Elon Musk announced that SpaceX is implementing over a thousand changes to its Super Heavy/Starship rocket and the launch pad before its second attempt to reach orbit, which is expected in six weeks. The changes include a modified stage separation system, hot staging technique, and adding shielding to the top of the Super Heavy stage. Engineers are also addressing engine problems and damage to the launch pad. The FAA will have to sign off on safety-related upgrades before a launch license will be granted. Musk estimates that SpaceX has invested over $2 billion in the Super Heavy/Starship program to date.
