SpaceX is about to launch the world’s biggest and tallest rocket once again. Elon Musk’s private space company has got its final approval from US federal regulators to launch Starship on Friday morning local central time. The first launch of the rocket initially appeared to go well, with the rocket launching up into the sky and preparing for its journey around Earth. But minutes later the spacecraft began to tumble and soon after that it blew up in a vast explosion. Since then, SpaceX has been working to comply with regulators including aviation authorities as well as those tasked with protecting the environment and wildlife around its base in Texas. The Federal Aviation Administration issued its license Wednesday, noting that SpaceX has met safety, environmental and other requirements to launch again. Elon Musk's rocket company said it was targeting Friday morning. After the self-destruct system blew up the rocket over the Gulf of Mexico, SpaceX made dozens of improvements to the nearly 400-foot (121-meter) rocket and to the launch pad, which ended up with a large crater beneath it. SpaceX has a $3 billion NASA contract to land astronauts on the lunar surface as early as 2025, using the spacecraft. A month ago, the FAA completed its safety review of the upcoming Starship launch. It needed more time to wrap up its environmental review. No one was injured in the first attempt, but the pad was heavily damaged as the rocket's 33 main engines ignited at liftoff. The U.S. Fish and Wildlife Service later reported that concrete chunks, steel sheets and other objects were hurled thousands of feet (hundreds of meters) from the pad. It also said a plume of pulverized concrete sent material several miles (up to 10 kilometers) away. Wildlife and environmental groups sued the FAA over what they considered to be the FAA’s failure to fully consider the environmental impacts of the Starship program near Boca Chica Beach. Plans call for the test flight to last 1 /1/2 hours and fall short of a full orbit of Earth. The spacecraft would go eastward, passing over the Atlantic, Indian and Pacific oceans before ditching near Hawaii. Nothing of value will be on board.
