Donald Trump watched the launch of Starship with Elon Musk, but the test flight did not go as planned

Elon Musk's SpaceX has conducted another Starship rocket launch in the presence of President-elect Donald Trump, but the test flight did not go perfectly.

According to foreign media, Telegrafi reports, the 122m high rocket system, designed to land astronauts on the moon and crews on Mars, took off from Boca Chica, Texas.

But its "first part," called the Super Heavy, suddenly blew up in the Gulf of Mexico instead of trying to return to its launch pad, indicating something went wrong.

Trump's appearance signals a deepening alliance with Musk, who will benefit from his recent election victory.

As the media points out, the billionaire entrepreneur is expected to provide favorable treatment from the government, not only for SpaceX, but also Tesla, and help his companies.

Trump has also appointed Musk to co-lead a new government efficiency project.

After separating from the Starship second stage, the booster returned to Boca Chica in Texas, where it was supposed to be "captured and stuck" on what the company describes as "sticks."

But the "capture" was canceled just four minutes into the test flight and the booster fell into the water three minutes later.

The Starship rocket also fell about an hour later, but this time in the Indian Ocean, off the northern coast of Australia.

This was the sixth test for the world's largest and most powerful rocket that SpaceX and NASA hope to use to return astronauts to the Moon and eventually Mars.

NASA is paying SpaceX more than $4 billion to "put" astronauts on the moon via Starship on successive missions later this decade. /Telegraph/
