Rocket Lab CEO explains a flaw in Elon Musk’s plan
SpaceX’s Starship may do a lot, but it won’t do everything.
The company’s under-development rocket, first outlined in 2017, is designed to send humans to Mars and beyond. But at its unveiling, CEO Elon Musk said that he wanted “one booster and ship that replaces [the existing] Falcon 9, Falcon Heavy, and Dragon.” That means a ship that can also launch satellite constellations like Starlink.
But in an interview with Inverse, Rocket Lab CEO Peter Beck suggested that this vision might be a step too far. Speaking after the latest updates to its Neutron rocket project, Beck explained that the Starship wouldn’t help build satellite constellations of the future.
“If you want to populate Mars, then the Starship is the vehicle to do that,” he says. “If you want to deploy a bunch of constellations and spacecraft in low Earth orbit, 100 tons of payload is just not going to help you.”

The comments pour cold water on an often-touted feature of the Starship. Where the Falcon 9 can launch around 16 tonnes to low-Earth orbit in reusable configuration, the Starship can launch over 100 tonnes.
Beyond Musk’s comments at the unveiling, he has mentioned after that he plans to use the Starship for satellite launches. In June 2021, he wrote on Twitter that Starlink missions would move to Starship. Current Falcon 9 rockets launch up to 60 Starlink satellites at a time, which could mean a large increase in launch capacity.
Rocket Lab designed its Neutron, set for its first flight in 2024, to launch eight tonnes. Beck argues that a smaller capacity rocket is better for building out constellations because you can target multiple orbital planes with deliveries to orbit.
“If you want to put the constellation in one orbital plane, then that’s fine, but that’s not particularly useful,” Beck says. “Having multiple planes is generally more useful.”
Beck also argues that, using a smaller payload, it makes more sense for manufacturers to use a smaller rocket.
“You don’t get a discount for putting eight tonnes in a 100-tonne rocket,” he says. “The rocket price is the same.”
When paired with the Electron rocket, Beck argues that Rocket Lab can lift around 90 percent of all that’s planned within the coming decade. That still leaves Starship and others for heavy-lift missions.
A rocket that can replace Falcon 9, though? That all depends on whether SpaceX can offer launches at an attractive price. Musk claims the ship could cost just $2 million per launch, severely undercutting the Falcon 9’s $62 million price tag.
The race to make space more accessible than ever is heating up.
