US President Donald Trump signed an executive order aimed at simplifying regulations governing commercial rocket launches. The order targets expediting environmental review processes for launch licenses issued by the Federal Aviation Administration (FAA). Trump cited inefficient permitting as a hindrance to innovation and investment within US space markets. It calls for removal of outdated rules related to launch and reentry vehicles. The order could potentially benefit companies like SpaceX led by Elon Musk, despite recent disagreements. Environmental groups express concerns about risks associated with deregulating commercial spaceflight.
