【推荐1】Space X announced a new ________ on Tuesday for a venture that will send four tourists deeper into orbit than any private citizen before them, in a mission that could take place next year and easily cost more than $100 million.

The company signed the deal with Space Adventures, which is based in Washington and ________ as an intermediary(中介)to send eight space tourists to the International Space Station, or ISS, via Russian Soyuz rockets.

The first of these was Dennis Tito, who paid $20 million for an eight-hour stay on the ISS in 2001. The last to go was Cirque du Soleil founder Guy Laliberte, in 2009.

The new tourists would be carried on Space X’s Crew Dragon ________ , which was developed to transport NASA astronauts and is ________ to make its first crewed flight in the coming months.

Space Adventures said the mission would ________ five days, flying up to four passengers into space to Earth orbit.

“This is a free-flyer mission. No visit to the ISS. It will attempt to reach two to three times higher ________ than the station,” said Eric Anderson, founder of Space Adventures.

“At an altitude of three times the ISS, the view is 10 times,” said Anderson. The ________ altitude of ISS orbit is about 400 kilometers.

Space XPresident Gwynne Shotwell said in a ________ : “This historic mission will ________   to making spaceflight possible for all people who dream of it, and we are pleased to work with the Space Adventures’ team on the mission.”

The capsule was designed to take astronauts from the surface to the ISS. With just nine square meters in volume, there are no ________ areas to sleep, wash or use the bathroom.

Asked about the ________ , Tom Shelley, president of Space Adventure, said, “It’s not cheap.”

The cost of launching a Falcon 9 rocket is $62 million, according to publicly available ________ . Then there will be the cost of building a fresh Dragon capsule. Could it ________ $100million?

“Your ________ is correct, I can’t comment specifically on the numbers, but yeah those are the cost components,” he said.

“We have a pretty good network of ________ individuals around the world, many of whom we know are interested in spaceflight.”

The situation demonstrates a new online reality: the _______ of a new crop of artificial intelligence tools has made it cheaper and easier than ever to create realistic images, as well as audio and videos. And these images are likely to pop up with increasing frequency on social media.

While these AI tools may enable new means of expressing creativity, the spread of computer-generated media also threatens to further _______ the information ecosystem. That risks _______ the challenges for users, news organizations and social media platforms to tell what’s real. There are also concerns that Al-generated images could be misused.

Images, compared to the Al-generated text, can be _______ powerful in provoking emotions when people view them, said Claire Leibowicz, head of AI and media integrity at the Partnership on AI. That can make it harder for people to slow down and _______ whether what they’re looking at is real or fake. _______, bad guys could eventually attempt to create fake content in quantity in order to confuse Internet users and provoke certain behaviors.

Computer-generated image technology has improved rapidly in recent years, from the photoshopped image of a shark swimming through a flooded highway to the websites that four years ago began mass producing mostly _______ photos of people. But in most cases, the creators of the recent hot images don’t appear to have been ill-intended.

There are _______ by platforms, AI technology companies and industry groups to improve the transparency when a piece of content is generated by a computer. Platforms including Meta’s Facebook and Instagram, Twitter and YouTube have policies restricting or even ________ the sharing of media that could mislead users. But as use of AI-generated technologies grows, even such policies could threaten to ________ user trust.

Work is also underway on technical solutions that would, ________, watermark an AI-generated image or include a transparent label in an image’s metadata, so anyone viewing it across the Internet would know it was created by a computer. “All these institutions are ________ disclosure and transparency,” Leibowicz said.

A group of tech leaders, including Musk and Apple co-founder Steve Wozniak, this week wrote an open letter ________ artificial intelligence labs to stop the training of the most powerful AI systems for at least six months, citing “profound risks to society and humanity.” ________, it’s not clear whether any labs will take such a step. And as the technology rapidly improves and becomes accessible beyond a relatively small group of corporations doing responsible practices, lawmakers may need to get involved.
