The first African and Arab woman to go to space reveals her brutal routine to get the job: 4:30 a.m. training, while juggling a full-time tech gig

Published

Sara Sabry became the world’s first Egyptian astronaut after flying to space on Blue Origin’s New Shepard rocket on Aug. 4, 2022—marking the first time an Arab or African women has ever gone to space, all before even turning 30.

It’s a common childhood dream, but one that few realize. For starters, you need access to a plane just to rack up the 1,000 flight hours required to apply to programs like NASA.

For Sabry, the mission was even more impossible. She wasn’t born into a country with a space agency. There were no astronauts who looked like her. And she didn’t have elite connections or deep pockets.

So to get her foot in the door, the then 28-year-old had to wake up at 4:30 a.m. to squeeze in early-morning training and bioastronautics research, all before reporting to her full-time job as CTO of a Berlin-based tech startup by 9 a.m. 

Then after work, she’d work some more on her own start-up and space training—and it’s the kind of gruelling discipline she says young people today shouldn’t shy away from if they want to unlock their dreams.

“Back then it was, it was really, really, it was really tough,” she recalls in those early days of her career, speaking exclusively to Fortune during her stay in London for the 2025 American Express Leadership Academy. “You would wake up at night, and then you would go back at night, so you barely see the daylight ever.”

She says that she’d tackle the most important tasks of the day before 10 a.m., when others start to trickle online.

“I see a lot of young people now they’re wanting to take the easy route without working so hard. But the truth is, you have to make sacrifices. You have to put yourself through a lot of discomfort,” Sabry adds. “Of course, it’s not easy to wake up 4:30 a.m. every morning and be completely isolated from the world, right? But it goes to show that you can really transform your life—and you have so much control over your life.”

Sabry says the experience radically shifted how she viewed limitations tied to class, geography, and identity.

She didn’t have the passport, the platform, or the privilege, but she pushed through anyway. And in doing so, proved what’s possible when ambition is backed by relentless effort.

“It changed the way I see things now. Having gone to space and having done the thing that was impossible, honestly the likelihood of that happening was around 0.0%, unless I changed my nationality.”

She beat the odds—and over 7,000 other applicants for that Blue Origin flight—to make history.

Now, she’s made it—but still pulling 13-hour days and has a jet-setter schedule

Despite finding success, you still won’t find Sabry kicking up her feet. 

On top of being an astronaut, the now 32-year-old is also the executive director of Deep Space Initiative—a nonprofit she founded to make space more accessible—co-founder of the Egyptian Space Agency’s Ambassador program, and is completing a PhD in aerospace engineering. She is also conducting research on the engineering of the next generation of planetary spacesuits at the NASA-funded Humanspaceflight lab.

If that wasn’t enough, Sabry is building new ventures and growing a speaking career that’s taking her around the world. And with such a packed, jet-setting schedule, she’s learned to adapt her rigid routine into something more flexible. But that doesn’t mean she lies in.

“I haven’t lived in a one place in three years,” she says. “I have to live out of my suitcase, so you have to adapt.”

Nowadays, Sabry starts her day at around 6 a.m. with a workout, before responding to emails and doing “admin stuff.” 

“It’s not 4:30 a.m. anymore, because I have to work late these days,” she explains, adding that the time difference for international calls she has to take while often based in Egypt pushes her work schedule back, bringing her total workday to 13 hours. 

“My first meeting is at 9 a.m. and my last meeting is from 9 p.m. to 10 p.m. so I can’t be waking up too early,” Sabry continues. Eight hours of sleep is non-negotiable—and so is having every task for the day blocked out in her calendar.

“Because I’m balancing a PhD, two companies, my public speaking, and more, I think it’s really about scheduling. As soon as tasks are scheduled in my calendar, I don’t have to think about them,” she adds.

“It’s so easy to get distracted when you’re working on other things, and you think, ‘Oh I have to work on my research or I have to answer emails.’ But no, emails are going to stay in the inbox until the scheduled time for me to be looking at emails. Sometimes, of course, you have to do urgent things. But the things that are not super urgent? You pre-schedule.” 

Eyes on the prize: The cure for exhaustion 

If you feel exhausted just reading about Sabry’s routine, let alone copying it, she says there’s only one way to survive it: become obsessed by your mission.

Sabry said she had no other choice because the alternative was not giving it all and risk not achieving her dream.

“It was always this fight,” she explains. “I was never going to be given an opportunity. Having grown up knowing that things are just not going to be given to me, I never expected anything. It makes you work so much harder. But I never really resented it, or felt like, ‘Oh, I’m doing too much,’ because that was just the necessary thing to do to move forward. There was no other option.” 

And she says having a packed schedule helped her move forward with her goals because she didn’t even have time to think about anything else. 

“Most of the day you’re in the dark, but you’re so consumed by it—having that focus and not having time to look at what’s going on in different places was really, really key,” she tells Fortune

“So being so consumed and having just a really packed schedule, and knowing that I was investing in myself. When you’re working on things that you know are towards your purpose, it just gives you so much peace.”

Ultimately, she’d only be kicking herself today if she knew there was an extra hour or two in the day that she hadn’t used to push herself forward.

“If I wasn’t doing everything that I can and I could do more, then I wouldn’t feel at peace. Then I would kind of go through like the other rabbit hole of, you know, being kind of like extra tough on yourself. So by doing so much, it gave me peace.”

The rise of AI reasoning models comes with a big energy tradeoff

Published

on



Nearly all leading artificial intelligence developers are focused on building AI models that mimic the way humans reason, but new research shows these cutting-edge systems can be far more energy intensive, adding to concerns about AI’s strain on power grids.

AI reasoning models used 30 times more power on average to respond to 1,000 written prompts than alternatives without this reasoning capability or which had it disabled, according to a study released Thursday. The work was carried out by the AI Energy Score project, led by Hugging Face research scientist Sasha Luccioni and Salesforce Inc. head of AI sustainability Boris Gamazaychikov.

The researchers evaluated 40 open, freely available AI models, including software from OpenAI, Alphabet Inc.’s Google and Microsoft Corp. Some models were found to have a much wider disparity in energy consumption, including one from Chinese upstart DeepSeek. A slimmed-down version of DeepSeek’s R1 model used just 50 watt hours to respond to the prompts when reasoning was turned off, or about as much power as is needed to run a 50 watt lightbulb for an hour. With the reasoning feature enabled, the same model required 7,626 watt hours to complete the tasks.

The soaring energy needs of AI have increasingly come under scrutiny. As tech companies race to build more and bigger data centers to support AI, industry watchers have raised concerns about straining power grids and raising energy costs for consumers. A Bloomberg investigation in September found that wholesale electricity prices rose as much as 267% over the past five years in areas near data centers. There are also environmental drawbacks, as Microsoft, Google and Amazon.com Inc. have previously acknowledged the data center buildout could complicate their long-term climate objectives

More than a year ago, OpenAI released its first reasoning model, called o1. Where its prior software replied almost instantly to queries, o1 spent more time computing an answer before responding. Many other AI companies have since released similar systems, with the goal of solving more complex multistep problems for fields like science, math and coding.

Though reasoning systems have quickly become the industry norm for carrying out more complicated tasks, there has been little research into their energy demands. Much of the increase in power consumption is due to reasoning models generating much more text when responding, the researchers said. 

The new report aims to better understand how AI energy needs are evolving, Luccioni said. She also hopes it helps people better understand that there are different types of AI models suited to different actions. Not every query requires tapping the most computationally intensive AI reasoning systems.

“We should be smarter about the way that we use AI,” Luccioni said. “Choosing the right model for the right task is important.”

To test the difference in power use, the researchers ran all the models on the same computer hardware. They used the same prompts for each, ranging from simple questions — such as asking which team won the Super Bowl in a particular year — to more complex math problems. They also used a software tool called CodeCarbon to track how much energy was being consumed in real time.

The results varied considerably. The researchers found one of Microsoft’s Phi 4 reasoning models used 9,462 watt hours with reasoning turned on, compared with about 18 watt hours with it off. OpenAI’s largest gpt-oss model, meanwhile, had a less stark difference. It used 8,504 watt hours with reasoning on the most computationally intensive “high” setting and 5,313 watt hours with the setting turned down to “low.” 

OpenAI, Microsoft, Google and DeepSeek did not immediately respond to a request for comment.

Google released internal research in August that estimated the median text prompt for its Gemini AI service used 0.24 watt-hours of energy, roughly equal to watching TV for less than nine seconds. Google said that figure was “substantially lower than many public estimates.” 

Much of the discussion about AI power consumption has focused on large-scale facilities set up to train artificial intelligence systems. Increasingly, however, tech firms are shifting more resources to inference, or the process of running AI systems after they’ve been trained. The push toward reasoning models is a big piece of that as these systems are more reliant on inference.

Recently, some tech leaders have acknowledged that AI’s power draw needs to be reckoned with. Microsoft CEO Satya Nadella said the industry must earn the “social permission to consume energy” for AI data centers in a November interview. To do that, he argued tech must use AI to do good and foster broad economic growth.

SpaceX to offer insider shares at record-setting valuation

Published

on



SpaceX is preparing to sell insider shares in a transaction that would value Elon Musk’s rocket and satellite maker at a valuation higher than OpenAI’s record-setting $500 billion, people familiar with the matter said.

One of the people briefed on the deal said that the share price under discussion is higher than $400 apiece, which would value SpaceX at between $750 billion and $800 billion, though the details could change. 

The company’s latest tender offer was discussed by its board of directors on Thursday at SpaceX’s Starbase hub in Texas. If confirmed, it would make SpaceX once again the world’s most valuable closely held company, vaulting past the previous record of $500 billion that ChatGPT owner OpenAI set in October. Play Video

Preliminary scenarios included per-share prices that would have pushed SpaceX’s value at roughly $560 billion or higher, the people said. The details of the deal could change before it closes, a third person said. 

A representative for SpaceX didn’t immediately respond to a request for comment. 

The latest figure would be a substantial increase from the $212 a share set in July, when the company raised money and sold shares at a valuation of $400 billion.

The Wall Street Journal and Financial Times, citing unnamed people familiar with the matter, earlier reported that a deal would value SpaceX at $800 billion.

News of SpaceX’s valuation sent shares of EchoStar Corp., a satellite TV and wireless company, up as much as 18%. Last month, Echostar had agreed to sell spectrum licenses to SpaceX for $2.6 billion, adding to an earlier agreement to sell about $17 billion in wireless spectrum to Musk’s company.

The world’s most prolific rocket launcher, SpaceX dominates the space industry with its Falcon 9 rocket that launches satellites and people to orbit.

SpaceX is also the industry leader in providing internet services from low-Earth orbit through Starlink, a system of more than 9,000 satellites that is far ahead of competitors including Amazon.com Inc.’s Amazon Leo.

SpaceX executives have repeatedly floated the idea of spinning off SpaceX’s Starlink business into a separate, publicly traded company — a concept President Gwynne Shotwell first suggested in 2020. 

However, Musk cast doubt on the prospect publicly over the years and Chief Financial Officer Bret Johnsen said in 2024 that a Starlink IPO would be something that would take place more likely “in the years to come.”

The Information, citing people familiar with the discussions, separately reported on Friday that SpaceX has told investors and financial institution representatives that it is aiming for an initial public offering for the entire company in the second half of next year.

A so-called tender or secondary offering, through which employees and some early shareholders can sell shares, provides investors in closely held companies such as SpaceX a way to generate liquidity.

SpaceX is working to develop its new Starship vehicle, advertised as the most powerful rocket ever developed to loft huge numbers of Starlink satellites as well as carry cargo and people to moon and, eventually, Mars.

U.S. consumers are so strained they put more than $1B on BNPL during Black Friday and Cyber Monday

Published

on



Financially strained and cautious customers leaned heavily on buy now, pay later (BNPL) services over the holiday weekend.

Cyber Monday alone generated $1.03 billion (a 4.2% increase YoY) in online BNPL sales with most transactions happening on mobile devices, per Adobe Analytics. Overall, consumers spent $14.25 billion online on Cyber Monday. To put that into perspective, BNPL made up for more than 7.2% of total online sales on that day.

As for Black Friday, eMarketer reported $747.5 million in online sales using BNPL services with platforms like PayPal finding a 23% uptick in BNPL transactions.

Likewise, digital financial services company Zip reported 1.6 million transactions throughout 280,000 of its locations over the Black Friday and Cyber Monday weekend. Millennials (51%) accounted for a chunk of the sizable BNPL purchases, followed by Gen Z, Gen X, and baby boomers, per Zip.

The Adobe data showed that people using BNPL were most likely to spend on categories such as electronics, apparel, toys, and furniture, which is consistent with previous years. This trend also tracks with Zip’s findings that shoppers were primarily investing in tech, electronics, and fashion when using its services.

And while some may be surprised that shoppers are taking on more debt via BNPL (in this economy?!), analysts had already projected a strong shopping weekend. A Deloitte survey forecast that consumers would spend about $650 million over the Black Friday–Cyber Monday stretch—a 15% jump from 2023.

“US retailers leaned heavily on discounts this holiday season to drive online demand,” Vivek Pandya, lead analyst at Adobe Digital Insights, said in a statement. “Competitive and persistent deals throughout Cyber Week pushed consumers to shop earlier, creating an environment where Black Friday now challenges the dominance of Cyber Monday.”
