SpaceX’s Starship Super Heavy rocket, which is the world’s tallest, is ready for launch pad tests
SpaceX Starship’s Super Heavy Rocket is poised for what could be the final launch pad test before a likely orbital test flight in July.
The massive Super Heavy Booster 7, which has 33 Raptor engines, was transported to its orbital launch pad on June 23.
A huge robotic arm mounted the rocket on the launch pad.
It took a tremendous amount of work for the company to get to this point due to the sheer number of Raptor rocket engines in the Super Heavy.

Missiles gone? Elon Musk has said that SpaceX’s Starship Super Heavy Booster 7 will most likely be ready for an orbital test flight in July
A difference between SpaceX’s rockets and all the ones that came before them – theirs are reusable, which means a huge cost saving. The Super Heavy Booster 7, seen above while being transported to the South Texas launch site, has 33 Raptor engines
As Ars Technica notes that Aerojet Rocketdyne, which also makes propulsion rockets, plans to build just four RS-25 rocket engines for NASA this year.
By contrast, Musk’s company is now building at least four Raptor rocket engines a week. The two different engines are comparable in power.
The South Texas site includes a massive launch and catch tower that will support the fully-stacked missile during all operations.
Shortly after launch, it captures the first stage booster with huge robotic ‘chopsticks’ as the rocket slows to the ground.
“This tower took 13 months from design to construction,” Musk said earlier during a SpaceX presentation.
Musk has long talked about the need for humans to become a multiplanetary species. A Starship SN8 rocket is seen at the SpaceX facility in Boca Chica, Texas

“We’re aiming for quick reusability, so the booster is going to take off and then fly back to the launch tower and land ambitiously on the arms, which sounds insane,” Musk said, explaining the “catch” part of the launch and capture tower.
“If it comes in too fast and slides off the poor, I think it’ll be ‘goodbye to the poor’.”
SpaceX, which has had at least 24 successful launches this year and sent everything from Starlink satellites to classified payloads into orbit, has come a long way since its previous failures.
On June 28, 2015, a 208-foot-tall SpaceX Falcon 9 rocket bound for the International Space Station exploded minutes after liftoff from Cape Canaveral Air Force Station in Florida.
The lost rocket reportedly carried more than 4,000 pounds of payload, including experiments, a spacesuit, a camera to record meteor blasts and a docking adapter that would have served as a parking space for future crew capsules.
SpaceX CEO Elon Musk has tweeted extensively about SpaceX’s ambitions and has given media presentations, like the one above, about its progress.
SpaceX has had a number of launch failures over the years. Above: Debris from a National Wildlife Refuge after an unmanned SpaceX Starship prototype failed to land safely in Boca Chica, Texas
It was later determined that the accident was caused by overpressure in the liquid oxygen tank of the rocket’s upper stage.
With Musk at the helm, SpaceX has made rapid strides in recent years.
The tech billionaire and likely Twitter owner said Starship would be ready to fly in July and that the company will have another Starship stack ready by August.
If SpaceX holds a full wet dress rehearsal — filling the booster with more than 3,000 tons of liquid oxygen and liquid methane — it would be its first for Super Heavy, Teslarati reports.
NASA and SpaceX announced Tuesday that they are targeting the launch of the CRS-25 commercial resupply services mission to the International Space Station no earlier than July 14.
