SpaceX fires up Starship engines ahead of fifth test flight

SpaceX has just performed a static fire of the six engines on its Starship spacecraft as it awaits permission from the Federal Aviation Administration (FAA) for the fifth test flight of the world’s most powerful rocket.

The Elon Musk-led spaceflight company shared footage and an image of the test fire on X (formerly Twitter) on Thursday. It shows the engines firing up while the vehicle remained on the ground.

For flights, the Starship spacecraft is carried to orbit by the first-stage Super Heavy booster, which pumps out 17 million pounds of thrust at launch, making it the most powerful rocket ever built.

The Super Heavy booster and Starship spacecraft — collectively known as the Starship — have launched four times to date, with the performance of each test flight showing improvements over the previous one.

The first one, for example, exploded shortly after lift off from SpaceX’s Starbase facility in Boca Chica, Texas, in April last year, while the second effort, which took place seven months later, achieved stage separation before an explosion occurred — an incident that was captured in dramatic footage. The third and fourth flights lasted much longer and achieved many of the mission objectives, including getting the Starship spacecraft to orbit.

The fifth test flight isn’t likely to take place until November at the earliest, according to a recent report. It will involve the first attempt to use giant mechanical arms to “catch” the Super Heavy booster as it returns to the launch area. SpaceX recently expressed extreme disappointment at the time that it’s taking the FAA to complete an investigation that will pave the way for the fifth Starship test, and has said that it’ll be ready to launch the vehicle within days of getting permission from the FAA.

Once testing is complete, NASA wants to use the Starship, along with its own Space Launch System rocket, to launch crew and cargo to the moon and quite possibly for destinations much further into space such as Mars. NASA is already planning to use a modified version of the Starship spacecraft to land the first astronauts in five decades on the lunar surface in the Artemis III mission, currently set for 2026.

Climate change is making days longer, as the melting of glaciers and polar ice sheets causes water to move closer to the equator, fattening the planet and slowing its rotation, according to a recent study.

Research published in the Proceedings of the National Academy of Sciences used both observations and reconstructions to track variations of mass at Earth’s surface since 1900.

In the 20th century, researchers found that between 0.3 milliseconds per century and 1 millisecond per century were added to the length of a day by climate-induced increases. Since 2000, they found that number accelerated to 1.3 milliseconds per century.

“We can see our impact as humans on the whole Earth system, not just locally, like the rise in temperature, but really fundamentally, altering how it moves in space and rotates,” Benedikt Soja of ETH Zurich in Switzerland told Britain’s Guardian newspaper. “Due to our carbon emissions, we have done this in just 100 or 200 years, whereas the governing processes previously had been going on for billions of years. And that is striking.”

Researchers said that, under high greenhouse gas emission scenarios, the climate-induced increase in the length of a day will continue to grow and could reach a rate twice as large as the present one. This could have implications for a number of technologies humans rely on, like navigation.

“All the data centers that run the internet, communications and financial transactions, they are based on precise timing,” Soja said. “We also need a precise knowledge of time for navigation, and particularly for satellites and spacecraft.”

Google’s NotebookLM evolves: What IT leaders need to know about its enterprise applications

Google’s NotebookLM evolves: What IT leaders need to know about its enterprise applications

Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More


Google’s research tool NotebookLM made waves recently for a new feature that lets users generate what sounds a lot like podcasts. But while the company has been adding new features, it’s also seeing more and more use cases in the enterprise arena. 

NotebookLM lets users upload PDFs, websites, Google Docs, Google Slides and paste text into a notebook keeping information in one place. People can also ask Gemini questions about the documents inside the notebook. First launched in July 2023 and generally available in the U.S. since Dec. 2023, NotebookLM has slowly expanded the kinds of files it can read.

However, one use case that has seen an uptick is through corporate teams sharing research and information on NotebookLM.

Raiza Martin, product manager at Google handling NotebookLM, told VentureBeat that they’re seeing corporate teams take advantage of the product’s organizational capabilities that let people find the information they need in one place. 

“We saw students using it to accelerate their learning and understanding and analysis, but we also know that the same thing students are doing is the exact same things that professionals are trying to do,” Martin said, adding that over months, Google has seen “an equal, if not larger amount of professionals using NotebookLM.”

Make a podcast to explain your research

Since launching NotebookLM, Google has slowly added new capabilities to the platform. The newest update allows users to generate audio explaining information in the notebook, with two speakers discussing the topic. 

“The conversation style is the first one that we picked because we thought it was novel, and in our early test, it was very engaging. The double speaker dynamic helped people sort of latch on to the content in a totally different way than a single speaker,” Martin said.

Google observed users and teams have used NotebookLM to bring together research and analysis, even some other information employees may need to know. One way enterprises can use NotebookLM is as a shortcut to store data that ultimately makes its way to retrieval augmented generative (RAG) search queries. Martin said NotebookLM itself is a RAG tool that benefits from Google’s Gemini 1.5 Pro. 

I got to use the audio generation feature early and was able to point it to one of my notebooks. I had given NotebookLM several documents about global AI regulations, such as the text of the European Union’s AI Act. The audio it generated summarized the act, but since the other file in the same notebook was an analytical blog post, the discussion took sides. To me, it sounded a lot like the tech-related podcasts I regularly listen to, without the personal banter between hosts.

Some users have begun posting how they’ve used the audio feature, including explaining code bases. 

It can be used to summarize blog posts as well. 

“This is the first of many formats, but in the future, we’ll give you knobs so you can change the number of speakers, the types of voices used and the content altogether,” said Martin.

Different use cases for NotebookLM 

Part of the growth of NotebookLM has been users exploring different use cases for it, and Martin said it means it’s usually up to users to figure out how to make it work for them. Some use cases have been very interesting, including a Dungeons and Dragons dungeon master using it to keep track of a campaign. 

“I think there’s still a lot of education in terms of connecting users on how to use the tool and why this type of tool might be valuable, but I would say that I’m really encouraged by the rate at which people are seeing that value and have used NotebookLM,” Martin said. 

Martin said NotebookLM will remain, for now, a standalone tool. However, some of the learnings from the tool could make their way to other Google productivity platforms.

The Buck Moon is almost here. Here’s when and where to see July’s full moon.

The Buck Moon is almost here. Here's when and where to see July's full moon.


The next full moon is arriving just in time for the weekend. According to NASA, the Buck Moon will make an appearance for three days, from Friday evening to Monday morning, reaching its peak at 6:17 a.m. EDT on Sunday.

The moon is also known as the Thunder Moon, given its overlap with thunderstorm season.

NASA advised viewers to stay safe from the lightning that comes with the storms, but also to indulge in a little fun as the Buck Moon arrives: “As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon.”

Why is it called the Buck Moon?

The name stems from a tradition established by the Maine Farmers’ Almanac in the 1930s, according to NASA, when the publication started listing the names of full moons. The Algonquin tribes of the Northeast reportedly called this month’s moon the Buck Moon – a nod to the deer that emerge this time of year.

“Early summer is normally when the new antlers of buck deer push out of their foreheads in coatings of velvety fur,” NASA said.

Other monikers for July’s full moon include Thunder Moon, Asalha Puja, Guru Full Moon, Hay Moon. and Mead Moon.

When will the next full moon take place?

August’s full moon — known as the Sturgeon Moon, according to the almanac.com — will peak on Monday, Aug. 19. This will be the first supermoon of the year, which means it will appear brighter and larger than other full moons.

Another event for stargazers to look forward to is a meteor shower on Saturday, July 31. Those on the East Coast will have to rise early if they want to catch the spectacle of light. According to NASA, the best time to see the shower from Washington, D.C., will be around 2 a.m.

UPchieve, an online tutor app for low-income students, launches a free tool for teachers

Published

UPchieve, the free, 24/7 online tutoring and college counseling app for low-income students, announced Thursday it’s giving teachers in Title 1 middle schools and high schools a new tool to ensure their students get the academic support they need.

The new offering, called “UPchieve for Teachers,” allows teachers to offer 1:1 support to their students. They can invite students to sign up for tutoring, create classes, and monitor students’ platform usage. Previously, students had to sign up for tutoring services themselves, but with this new product, teachers can now recommend students for 1:1 tutoring at no cost. In the coming weeks, they’ll also be able to assign tutoring sessions to entire classes.

UPchieve for Teachers is available to educators working in Title 1 middle schools and high schools. Title 1 is a federal aid program provided to K-12 schools with the highest number of low-income families within school districts. Approximately 43% of public schools qualify for Title I funding, with fewer than 50,000 schools benefiting from the program.

This new offering is expected to help UPchieve expand its user base by reaching students who may not be aware of free services like this or who may not be actively seeking additional assistance.

“The product is going to be really valuable to teachers because it’s going to help them accomplish some of the hardest parts of their job,” founder Aly Murray told TechCrunch. “Students are coming into the class with different gaps in their foundational skills. Teachers have to try to support all of their students, but there’s not enough time to support each student individually, so that’s a natural place where a tutor can help. We’re really excited about launching a product that’s going to give teachers more control.”

UPchieve was founded in 2016, shortly after Murray graduated from the University of Pennsylvania. As a former low-income student herself, she struggled to access academic support services throughout her schooling and wanted to make it easy for other students to be able to get help whenever they needed it, even when working on homework late at night. 

“I was raised by a single mom, and as an immigrant to the United States, she often wasn’t able to help me with schoolwork and with my college applications. And so that had a big impact on my life. It made things very difficult, and I found that I often needed help late at night when there was really nowhere I could turn to for support,” Murray said. 

UPchieve says it has matched over 190,000 tutoring requests from more than 20,000 students across all 50 states. Its 24/7 online tutoring sessions are conducted in the in-app messenger or via voice chat on the web or mobile app. UPchieve covers over 30 subjects, including math, science, English, history, humanities, and more.

Tutors can volunteer by signing up on the website. Volunteers can even be students themselves; however, they must be in 9th grade or higher. UPchieve currently has around 2,400 tutors active on the platform.

“All of the volunteers on UPchieve go through a background screening, training, and certification process to become a volunteer tutor. Before they’re ever going to work with a student, they have to pass a quiz in every subject that they want to help students with,” Murray explained.

Similar to other edtech companies, the company utilizes OpenAI’s GPT-4o to assist tutors in providing AI-generated feedback and progress reports to students after the sessions are over. In the future, the company also plans to use AI to help tutors create practice problems and offer AI-generated summaries of student sessions through its Teachers product. 

“We have no plans to replace our human tutors with AI tutors anytime in the near future,” Murray added.

As a nonprofit organization, UPchieve relies on charitable donations, grants, and paid partnerships with schools, districts, and corporations. Donors include Atlassian, AT&T, the Bill & Melinda Gates Foundation, Guggenheim Capital, Goldman Sachs, J.P. Morgan, the Skyline Foundation, and Verizon. 

UPchieve has partnered with over 50 schools, and each school or organization pays a $10,000 partnership fee per year or is sponsored by a donor or corporation who pays the fee on their behalf. The company also graduated from Y Combinator’s Winter 2021 batch.

In 2023, UPchieve raised over $4 million through philanthropy and earned revenue from paid partnerships. The company claims its annual recurring revenue (ARR) is currently $840,000, which comes solely from paid and sponsored partnerships.
