NASA is kicking off its new moon program with a test flight of a brand-new rocket and capsule.
Liftoff was slated for early Wednesday from Kennedy Space Center in Florida. The test flight aims to send an empty crew capsule into a far-flung lunar orbit, 50 years after NASA’s famed Apollo moonshots.
The project is years late and billions over budget. The price tag for the test flight: more than $4 billion.
A rundown of the new rocket and capsule, part of NASA’s Artemis program, named after Apollo’s mythological twin sister:
Rocket power
At 322 feet (98 meters), the new rocket is shorter and slimmer than the Saturn V rockets that hurled 24 Apollo astronauts to the moon a half-century ago. But it’s mightier, packing 8.8 million pounds (4 million kilograms) of thrust. It’s called the Space Launch System rocket, SLS for short, although a less clunky name is under discussion. Unlike the streamlined Saturn V, the new rocket has a pair of side boosters refashioned from NASA’s space shuttles. The boosters peel away after two minutes, just like the shuttle boosters. The core stage keeps firing before crashing into the Pacific. Less than two hours after liftoff, an upper stage sends the capsule, Orion, racing toward the moon.
Moonship
NASA’s high-tech, automated Orion capsule is named after the constellation, among the night sky’s brightest. At 11 feet (3 meters) tall, it’s roomier than Apollo’s capsule, seating four astronauts instead of three. For the test flight, a full-size dummy in an orange flight suit occupies the commander’s seat, rigged with vibration and acceleration sensors. Two other mannequins made of material simulating human tissue — heads and female torsos, but no limbs — measure cosmic radiation, one of the biggest risks of spaceflight. Unlike the rocket, Orion has launched before, making two laps around Earth in 2014. For the test flight, the European Space Agency’s service module was attached for propulsion and solar power via four wings.
Flight plan
Orion’s flight is set to last 25 days from its Florida liftoff to Pacific splashdown, about the same as astronaut trips. It takes nearly a week to reach the moon. After whipping closely around the moon, the capsule enters a distant orbit with a far point of close to 40,000 miles (64,000 kilometers). That would put Orion about 270,000 miles (435,000) from Earth, farther than Apollo. The big test comes at mission’s end, as Orion hits the atmosphere at 25,000 mph (40,000 kph) on its way to a splashdown in the Pacific. The heat shield uses the same material as the Apollo capsules to withstand reentry temperatures of 5,000 degrees Fahrenheit (2,750 degrees Celsius). But the advanced design anticipates the faster, hotter returns by future Mars crews.
Hitchhikers
Besides three test dummies, the test flight includes a slew of stowaways for deep space research. Ten shoebox-size satellites pop off once Orion is hurtling toward the moon. NASA expects some to fail, given the low-cost, high-risk nature of these mini satellites. In a back-to-the-future salute, Orion carries a few slivers of moon rocks collected by Apollo 11’s Neil Armstrong and Buzz Aldrin in 1969, and a bolt from one of their rocket engines, salvaged from the sea a decade ago.
Apollo vs. Artemis
More than 50 years later, Apollo still stands as NASA’s greatest achievement. Using 1960s technology, NASA took just eight years to go from launching its first astronaut, Alan Shepard, and landing Armstrong and Aldrin on the moon. By contrast, Artemis already has dragged on for more than a decade, despite building on the short-lived moon exploration program Constellation. Twelve Apollo astronauts walked on the moon from 1969 through 1972, staying no longer than three days at a time. For Artemis, NASA will draw from a diverse astronaut pool and is extending the time crews spend on the moon to at least a week. The goal is to create a long-term lunar presence that will grease the skids for sending people to Mars.
What’s next
There’s a lot more to be done before astronauts step on the moon again. A second test flight will send four astronauts around the moon and back, perhaps as early as 2024. A year or so later, NASA aims to send another four up, with two of them touching down at the lunar south pole. Orion doesn’t come with its own lunar lander like the Apollo spacecraft did, so NASA has hired Elon Musk’s SpaceX to provide its Starship spacecraft for the first Artemis moon landing. Two other private companies are developing moonwalking suits. The sci-fi-looking Starship would link up with Orion at the moon and take a pair of astronauts to the surface and back to the capsule for the ride home. So far, Starship has only soared six miles (10 kilometers).

FBI Director Christopher Wray said on Tuesday that the bureau has “national security concerns” about popular short-form video hosting app TikTok as the Chinese-owned company seeks U.S. government approval to continue operating in the country.
Speaking during a U.S. House of Representatives Homeland Security Committee hearing on “worldwide threats to the homeland,” Wray said the FBI’s concerns about TikTok include “the possibility that the Chinese government could use it to control data collection on millions of users.”
There is also concern, Wray said in response to a question, that the Chinese government could “control the recommendation algorithm, which could be used for influence operations … or to control software on millions of devices, which gives the opportunity to potentially technically compromise personal devices.”
In written testimony, Wray called the foreign intelligence and economic threat from China “the greatest long-term threat to our nation’s ideas, innovation, and economic security.”
But he declined to answer in an open session a lawmaker’s question about whether the Chinese government has been leveraging TikTok to collect data about U.S. citizens.
Concerns about ties to Chinese government
TikTok’s ties to the Chinese government have been a flashpoint among U.S. lawmakers and officials for years. The app grew in popularity in recent years after its parent company, ByteDance, a China-based company with suspected ties to the Chinese government, bought and later absorbed Musical.ly, which allowed users to create and share lip-sync videos.
Citing national security concerns, then-President Donald Trump issued an executive order in 2020 that would effectively ban TikTok in the United States. But the social platform sued to block Trump’s executive order.
Last year President Joe Biden revoked the Trump directive, asking the Treasury Department to examine security concerns associated with the app.
The Committee on Foreign Investment in the United States (CFIUS), an interagency body headed by the Treasury Department that reviews the national security implications of foreign investments in U.S. companies, has been examining TikTok’s proposal to continue to remain active in the U.S. market and the risks associated with it.
Noting that the FBI’s foreign investment unit is part of the CFIUS review process, Wray said that “our input would be taken into account in any agreements that might be made to address the issue.”
U.S. lawmakers question how data used
Although TikTok has denied having ties to China’s ruling Communist Party, U.S. lawmakers have long expressed concern about the Chinese government’s ability to access U.S. user data collected by the app.
Questioning Wray during Tuesday’s hearing, Republican Representative Diana Harshbarger cited a recent Forbes article that reported ByteDance “planned to use the TikTok app to track the physical location of specific American citizens.”
TikTok later dismissed the allegation raised in the article, saying in a statement it “does not collect precise GPS location information from U.S. users.”
In a June letter, TikTok sought to reassure U.S. lawmakers about its data security, writing that it now stores “100% of US user data, by default, in the Oracle cloud environment.”
‘Spinach’ vs. ‘opium’ versions
Last week, the U.S. TV news magazine “60 Minutes” reported that TikTok has two versions — a limited, educational “spinach version” for Chinese consumers, and an addictive “opium version” for the rest of the world.
While the version used in the West “has kids hooked for hours at a time,” in China, children under 14 years can use TikTok for only 40 minutes per day and view only videos about science experiments, museum exhibits, patriotic videos and educational videos, according to “60 Minutes.”
Wray said the online “threat to our youth is something we’re always concerned about.” The FBI is just as concerned about the way the Chinese government uses its laws as “an aggressive weapon against companies, both U.S. companies and Chinese companies,” he said.
“Under Chinese law, Chinese companies are required to essentially — and I’m going to shorthand here — basically do what the Chinese government wants them to do, in terms of sharing information or serving as a tool of the Chinese government,” Wray said. “And so, that’s plenty of reason by itself to be concerned.”
Beijing has denied similar allegations in the past.
