The system also proved it could open and close in just 1.5 seconds under realistic conditions.Neutron can carry up to 13,000 kg to orbit. The rocket uses carbon composite construction, making it the largest launch vehicle of its type. Development started in late 2021, putting it on pace to be one of the fastest commercially developed rockets ever.What Analysts Are SayingThe fairing will be integrated at Launch Complex 3 in Virginia.
