Donald Trump is reportedly planning to attend the launch of Elon Musk’s spaceship.

The president-elect was expected to travel to the launch facility in Texas on Tuesday after the Federal Aviation Administration issued temporary flight restrictions over the area to coincide with the launch.

Flight restrictions in place over Trump’s Mar-a-Lago resort in Palm Beach, Florida, will be lifted for a short time during the same period.

It’s a sign of Trump’s growing relationship with Musk, who has spent an estimated $200 million through a campaign group to boost Republicans’ election efforts in key swing states.

Since Trump’s victory this month, the Tesla billionaire has been at his side almost constantly. He is staying at his resort in Florida and traveling with him to meet Republicans in Washington DC and go to a UFC fight in New York.

Trump’s transition team did not respond to requests for comment. However, two people familiar with the president-elect’s schedule told The New York Times that he planned to attend the SpaceX launch on Tuesday.

Musk’s company will conduct its sixth test of Starship, the largest rocket ever built, at 5 p.m. Eastern Time.

It comes after reports that SpaceX planned to sell insider shares worth $135 each, which would give the rocket company a valuation of more than $250 billion. In June, its value was estimated at around $210 billion, meaning a premium of around $40 billion over five months.

There is speculation that Musk, who is known for his ambition to put humans on Mars, could push Trump to relax regulations on private space flights.

Musk, already the richest man in the world, saw his net worth rise to around $320 billion in the wake of Trump’s election victory.

In the four days after Election Day, Tesla shares rose about 39 percent, boosting Musk’s net worth by about $70 billion as most of his wealth is wrapped up in shares of his electric vehicle maker .

SpaceX’s projects are not without controversy: In June, it was reported that Starship generated sonic booms so powerful it risked causing property damage near its South Texas launch site.

An independent engineer claimed that for residents of South Padre Island and Port Isabel, about six miles from the site, this was the equivalent of being 200 feet away from a Boeing 747 during takeoff, The New York Times reported.

Conservation groups have also accused SpaceX of destroying fragile ecosystems with its test flights of Starship, which is the same height as a 30-story building.
