Elon Musk says, ‘I specialize in the impossible’; orbital refueling is Starship’s next big challenge |

Word Count: 729 | Estimated Reading Time: 4 minutes

Elon Musk, CEO of SpaceX, has called orbital refueling as the next major engineering hurdle for the company’s ambitious Starship rocket. Speaking at an event, Musk emphasized the complexity of developing a system that allows two massive spacecraft to dock in orbit and transfer propellant—something no one has achieved before. He framed the challenge as part of a broader vision to create a fully reusable rocket system capable of supporting long-duration missions to the Moon, Mars, and beyond. “I specialize in the impossible to merely late,” Musk quipped.

Elon Musk outlines Starship’s critical leap forward in orbit

Musk explained that successful orbital refueling would involve two Starships docking in space and transferring propellant, essentially transforming one vehicle into a fuel depot. This innovation is essential for enabling deep space missions, especially those targeting Mars, which require significantly more fuel than can be carried on a single launch. Musk hinted at the possibility of creating an orbital propellant depot to streamline future missions.Beyond refueling, Musk noted another formidable challenge: creating a fully reusable orbital heat shield. “No one has ever done this before,” he said. Heat shields typically degrade after reentry, making reusability difficult. However, for Starship to become economically viable and mission-ready, solving this engineering issue is paramount.

Starship aims to slash launch costs dramatically

Musk reiterated that the end goal is to make spaceflight dramatically cheaper. A fully reusable rocket and booster system would reduce costs to less than those of the original Falcon 1 rocket, revolutionizing space logistics. Lower costs could open the door to commercial space travel, lunar bases, and sustained Martian exploration.Musk’s remarks also came amid rising political tensions. President Donald Trump recently questioned government subsidies for Musk’s ventures, and the administration is reportedly considering alternate partners for the $175 billion Golden Dome defense project. Musk defended SpaceX, claiming it wins NASA contracts by doing a better job for a fraction of the cost and that the subsidies Trump mentioned did not exist.

Starship’s next launch expected in August

The next major Starship launch is expected in August, and Musk promised further updates ahead of the event. With SpaceX racing toward its vision of interplanetary travel, the success or failure of orbital refueling will be a defining milestone in the company’s quest to reshape space exploration.
