Rather than docking with the International Space Station (ISS) like SpaceX’s other crewed missions, the mission’s Crew Dragon spacecraft will instead remain in Earth orbit for three days under its own power The crew will eat, drink, sleep, and use the toilet within the confines of their spacecraft, named Resilience, which boasts about three times the interior volume of a large car. To keep them occupied, the docking port of the spacecraft, which would normally be used to connect to the ISS, has been converted into a glass dome, affording the crew glorious panoramic views of Earth and the universe beyond.
Beyond this, the goals of the mission are limited. There are some scientific experiments planned, but the most notable aspect of the mission is what will not happen. In particular, none of the crew will directly pilot the spacecraft. Instead, it will be controlled autonomously and with the help of mission control back down on Earth. That is not a trivial change, explains McDowell, and there are risks involved. “For the first time, if the automatic systems don’t work, you could be in real trouble,” he says. “What this shows is the increased confidence in the software and automatic control systems that allow you to fly tourists without a chaperone.”
All of this combines to make the launch of Inspiration4 an exciting moment in human spaceflight, albeit one that has been tentatively attempted before. In the 1980s, NASA had hoped to begin something similar—the Space Flight Participant Program, an effort to give various private citizens the opportunity to fly to space on the space shuttle. “It was felt that some of the astronauts were a little reserved in their descriptions of the flight,” says author Alan Ladwig, who led the program. NASA wanted people who could communicate the experience better and selected a teacher, a journalist, and an artist.
The program, however, came to a tragic end. Its first participant, Christa McAuliffe, a teacher from New Hampshire, died in the space shuttle Challenger explosion of 1986, along with the other six members of the crew. The program was canceled, and the space shuttle program as a whole stagnated. Experts once envisioned it would fly hundreds of missions a year, but only 110 more launches took place in the subsequent 25 years, until the shuttles were retired in 2011.
The majority of space travel will remain the remit of professional astronauts and the extremely wealthy for the time being. If you’re not rich, you will still be limited to applying for competitions or hoping for a ticket from a wealthy benefactor—perhaps not the glorious future of space travel many envisioned.
But Inspiration4 shows that opportunities for more “regular” people to go to space, though few and far between, are available. “It is a milestone in human access,” says space historian John Logsdon, professor emeritus at George Washington University’s Space Policy Institute. “In a very simplistic sense, it means anybody can go.”
You won’t be flying in a Pan Am space plane on your way to a giant rotating space hotel just yet, but who’s to say what the future might hold. “This is a brand-new industry in its infancy, and we’re seeing the first steps,” says Forczyk. “We don’t know how far it’s going to run.”
A bot that watched 70,000 hours of Minecraft could unlock AI’s next big thing
The researchers claim that their approach could be used to train AI to carry out other tasks. To begin with, it could be used to for bots that use a keyboard and mouse to navigate websites, book flights or buy groceries online. But in theory it could be used to train robots to carry out physical, real-world tasks by copying first-person video of people doing those things. “It’s plausible,” says Stone.
Matthew Gudzial at the University of Alberta, Canada, who has used videos to teach AI the rules of games like Super Mario Bros, does not think it will happen any time soon, however. Actions in games like Minecraft and Super Mario Bros. are performed by pressing buttons. Actions in the physical world are far more complicated and harder for a machine to learn. “It unlocks a whole mess of new research problems,” says Gudzial.
“This work is another testament to the power of scaling up models and training on massive datasets to get good performance,” says Natasha Jaques, who works on multi-agent reinforcement learning at Google and the University of California, Berkeley.
Large internet-sized data sets will certainly unlock new capabilities for AI, says Jaques. “We’ve seen that over and over again, and it’s a great approach.” But OpenAI places a lot of faith in the power of large data sets alone, she says: “Personally, I’m a little more skeptical that data can solve any problem.”
Still, Baker and his colleagues think that collecting more than a million hours of Minecraft videos will make their AI even better. It’s probably the best Minecraft-playing bot yet, says Baker: “But with more data and bigger models I would expect it to feel like you’re watching a human playing the game, as opposed to a baby AI trying to mimic a human.”

We can now use cells from dead people to create new life. But who gets to decide?
His parents told a court that they wanted to keep the possibility of using the sperm to eventually have children that would be genetically related to Peter. The court approved their wishes, and Peter’s sperm was retrieved from his body and stored in a local sperm bank.
We have the technology to use sperm, and potentially eggs, from dead people to make embryos, and eventually babies. And there are millions of eggs and embryos—and even more sperm—in storage and ready to be used. When the person who provided those cells dies, like Peter, who gets to decide what to do with them?
That was the question raised at an online event held by the Progress Educational Trust, a UK charity for people with infertility and genetic conditions, that I attended on Wednesday. The panel included a clinician and two lawyers, who addressed plenty of tricky questions, but provided few concrete answers.
In theory, the decision should be made by the person who provided the eggs, sperm or embryos. In some cases, the person’s wishes might be quite clear. Someone who might be trying for a baby with their partner may store their sex cells or embryos and sign a form stating that they are happy for their partner to use these cells if they die, for example.
But in other cases, it’s less clear. Partners and family members who want to use the cells might have to collect evidence to convince a court the deceased person really did want to have children. And not only that, but that they wanted to continue their family line without necessarily becoming a parent themselves.
Sex cells and embryos aren’t property—they don’t fall under property law and can’t be inherited by family members. But there is some degree of legal ownership for the people who provided the cells. It is complicated to define that ownership, however, Robert Gilmour, a family law specialist based in Scotland, said at the event. “The law in this area makes my head hurt,” he said.
The law varies depending on where you are, too. Posthumous reproduction is not allowed in some countries, and is unregulated in many others. In the US, laws vary by state. Some states won’t legally recognize a child conceived after a person’s death as that person’s offspring, according to the American Society for Reproductive Medicine (ASRM). “We do not have any national rules or policies,” Gwendolyn Quinn, a bioethicist at New York University, tells me.
Societies like ASRM have put together guidance for clinics in the meantime. But this can also vary slightly between regions. Guidance by the European Society for Human Reproduction and Embryology, for example, recommends that parents and other relatives should not be able to request the sex cells or embryos of the person who died. That would apply to Peter Zhu’s parents. The concern is that these relatives might be hoping for a “commemorative child” or as “a symbolic replacement of the deceased.”
