NASA is scheduled to launch a "planetary defense-driven test" late Tuesday night.

The goal of the Double Asteroid Redirection Test (DART) is to adjust the speed and path of an asteroid by using kinetic impactor technology.

The asteroid DART will be targeting is not a threat to Earth, NASA said.

"While no known asteroid larger than 140 meters in size has a significant chance to hit Earth for the next 100 years, only about 40 percent of those asteroids have been found as of October 2021," NASA said.

The DART spacecraft is scheduled to launch at 10:20 p.m. PT aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California.

The spacecraft is expected to reach its destination in September 2022 and begin testing its impact on the asteroid.

The European Space Agency says this will be the first time humans have tried to alter the dynamics of a solar system body, according to CNN.

VAN HORN, Texas —

Jeff Bezos blasted into space Tuesday on his rocket company’s first flight with people on board, becoming the second billionaire in just over a week to ride his own spacecraft.

The Amazon founder was accompanied by a hand-picked group: his brother, an 18-year-old from the Netherlands and an 82-year-old aviation pioneer from Texas — the youngest and oldest to ever fly in space.

Named after America’s first astronaut, Blue Origin’s New Shepard rocket soared from remote West Texas on the 52nd anniversary of the Apollo 11 moon landing, a date chosen by Bezos for its historical significance. He held fast to it, even as Virgin Galactic’s Richard Branson pushed up his own flight from New Mexico in the race for space tourist dollars and beat him to space by nine days.

Unlike Branson’s piloted rocket plane, Bezos’ capsule was completely automated and required no official staff on board for the anticipated 10-minute, up-and-down flight.

Blue Origin was shooting for an altitude of roughly 66 miles, more than 10 miles higher than Branson’s July 11 ride. The 60-foot booster accelerated to Mach 3 or three times the speed of sound to get the capsule high enough, before separating and landing upright.

The passengers had several minutes of weightlessness to float around the spacious white capsule. The window-filled capsule landed under parachutes, with Bezos and his guests briefly experiencing nearly six times the force of gravity, or 6 G’s, on the way back.

Sharing Bezos’ dream-come-true adventure was Wally Funk, from the Dallas area, one of 13 female pilots who went through the same tests as NASA’s all-male astronaut corps in the early 1960s but never made it into space.

Joining them on the ultimate joyride was the company’s first paying customer, Oliver Daemen, a last-minute fill-in for the mystery winner of a $28 million auction who opted for a later flight. The Dutch teen’s father took part in the auction, and agreed on a lower undisclosed price last week when Blue Origin offered his son the vacated seat.

Blue Origin — founded by Bezos in 2000 in Kent, Washington, near Amazon’s Seattle headquarters — has yet to open ticket sales to the public or reveal the price. For now, it’s booking auction bidders. Two more passenger flights are planned by year’s end, said Blue Origin CEO Bob Smith.

The recycled rocket and capsule that carried up Tuesday’s passengers were used on the last two space demos, according to company officials.

Virgin Galactic already has more than 600 reservations at $250,000 apiece. Founded by Branson in 2004, the company has sent crew into space four times and plans two more test flights from New Mexico before launching customers next year.

Blue Origin’s approach was slower and more deliberate. After 15 successful unoccupied test flights to space since 2015, Bezos finally declared it was time to put people on board. The Federal Aviation Administration agreed last week, approving the commercial space license.

Bezos, 57, who also owns The Washington Post, claimed the first seat. The next went to his 50-year-old brother, Mark Bezos, an investor and volunteer firefighter, then Funk and Daemen. They spent two days together in training.

University of Chicago space historian Jordan Bimm said the passenger makeup is truly remarkable. Imagine if the head of NASA decided he wanted to launch in 1961 instead of Alan Shepard on the first U.S. spaceflight, he said in an email.

“That would have been unthinkable!” Bimm said. "It shows just how much the idea of who and what space is for has changed in the last 60 years.”

Bezos stepped down earlier this month as Amazon’s CEO and just last week donated $200 million to renovate the National Air and Space Museum. Most of the $28 million from the auction has been distributed to space advocacy and education groups, with the rest benefiting Blue Origin’s Club for the Future, its own education effort.

Fewer than 600 people have reached the edge of space or beyond. Until Tuesday, the youngest was 25-year-old Soviet cosmonaut Gherman Titov and the oldest at 77 was Mercury-turned-shuttle astronaut John Glenn.

Both Bezos and Branson want to drastically increase those overall numbers, as does SpaceX’s Elon Musk, who’s skipping brief space hops and sending his private clients straight to orbit for tens of millions apiece, with the first flight coming up in September.

Despite appearances, Bezos and Branson insist they weren’t trying to outdo each other by strapping in themselves. Bezos noted this week that only one person can lay claim to being first in space: Soviet cosmonaut Yuri Gagarin, who rocketed into orbit on April 12, 1961.

“This isn’t a competition, this is about building a road to space so that future generations can do incredible things in space,” he said on NBC’s ”Today.”

Blue Origin is working on a massive rocket, New Glenn, to put payloads and people into orbit from Cape Canaveral, Florida. The company also wants to put astronauts back on the moon with its proposed lunar lander Blue Moon; it’s challenging NASA’s sole contract award to SpaceX.
