Welcome to Edition 9.04 of the Rocket Report! We've had to wait an extra week for SpaceX to get its 13th Starship test flight off the ground. A last-second abort on July 16 led engineers to roll the booster back to its hangar in South Texas to swap out engines. Starship is now back on the launch pad. Liftoff is set for Friday evening. A flawless launch and reentry will put SpaceX on the cusp of an orbital flight later this year. Ars will have a comprehensive recap story after the completion of the test flight.

India's first private rocket reaches orbit. Indian space officials celebrated the debut flight of Skyroot Aerospace’s Vikram-1 rocket, India’s first fully commercial satellite launcher, as a “grand success” Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal, Ars reports. The Vikram-1 lifted off from India’s primary spaceport on Sriharikota Island around midday local time. The launch was delayed more than a half-hour to resolve a last-minute technical problem. The countdown resumed, culminating in the command to ignite Vikram-1’s solid-fueled first stage booster to propel the rocket off the launch pad.
Running DOOM on weird obscure hardware is a fun hacker pastime that’s been around for a long time now. It’s always enjoyable to see someone port it to an egg timer, or a hat, or whatever else. But what about running the iconic shooteron a CPU of your very own? [Armaan] and [Liam] have done just that.
The CPU in question was designed at the logic gate level, deployed on to an FPGA, and hooked up with the necessary peripherals to run as a going concern. Early testing of the CPU involved running straightforward code to generate Mandelbrot sets and to play a simple game of Pong. But [Armaan] and [Liam] had bigger goals: to port the game that everybody ports to everything. Doing that took some work.
To get DOOM running, the CPU had to get faster, and it needed many tweaks to how memory was handled. There was also work to be done to create a keyboard interface, an HDMI video output, and a hardware timer. From there, the game itself had to then be ported to the custom CPU’s architecture. Eventually, the duo had the game running… at a glacial 0.7 FPS. A success, but not the magical end result that was desired. A bump to clock speed and further optimizations and compiler tweaks eventually got the game up to an impressive 15-20 FPS. The goal for future work is to push it to an entirely-playable figure of 30 FPS or better.
It’s worth checking out the (apparently unembeddable) videos on Instagram to see the CPU in action. We’ve also featured plenty of fun DOOM ports before, too. If you’re brewing up custom CPUs or DOOMports of your own, keep them coming to the tipsline. The latter in particular is often a wonderful milk run for the writer that happens across it. Happy hacking out there!
A study found leading AI chatbots can outperform people at easing anger and fear, raising uncomfortable questions about who we increasingly turn to during difficult moments.
Welcome to Edition 9.03 of the Rocket Report! SpaceX counted down all the way to T-0 on Thursday evening in South Texas before a handful of Raptor engines decided not to light at ignition of the rocket. It is not clear whether the vehicle can be worked on at the pad, or whether Starship will need to be de-stacked before this can occur. In any case, a few days delay beats a significant issue in flight.

Vikram-1 rocket gets a launch date. The debut launch attempt by Skyroot Aerospace of its Vikram-1 rocket is now set for July 18, at 11:30 am local time in India. This will be the first time a commercial rocket developed in India attempts to reach orbit. Designed to carry small satellites weighing up to 350 kg to low-Earth orbit, Vikram-1 is targeting a 450 km orbit at a 60-degree inclination.
For year after year, more Americans have bought Toyota RAV4s than anything that isn't a pickup truck. The brand's reputation for solid reliability has kept it ahead of SUVs from other automakers, and the nation's embrace of SUVs and crossovers relegated the poor old Camry to near-bottom of the top 10. For the latest generation—the sixth since 1994—all RAV4s are electrified. Most will use a mix of internal combustion engine and brakes to recharge their hybrid powertrains' traction batteries, like the millions of Priuses out there on the roads. But there's also a plug-in hybrid EV option, with an all-new powertrain with some noticeable improvements compared to the outgoing PHEV.
Just as Toyota's designers and engineers have tried to improve on the previous RAV4 with each successive generation, their counterparts in the powertrain department have similarly been iterating and improving the combination of electric motors and piston engine. Under the hood there's a naturally aspirated 2.5 L four-cylinder engine that operates on the Atkinson-cycle, aided by variable valve timing on both intake and exhaust sides.
The engine, which on its own generates 186 hp (139 kW) and 172 lb-ft (233 Nm), is connected to one of two electric motors under the RAV4's hood, as well as to Toyota's electronically controlled variable ratio transmission.
Welcome to Edition 9.02 of the Rocket Report! Our attention in the coming days turns to Asia, where there are a couple of notable rocket debuts. Up first is the Long March 10B on Friday, a medium-lift rocket with a reusable first stage. After launch this stage will attempt a landing on a recovery ship. Then, as early as Sunday, the private Indian company Skyroot may attempt to launch its first rocket, Vikram-1.

RFA sets launch date for August. Almost two years after an RFA One first stage burst into flames during a static fire test, German rocket-builder Rocket Factory Augsburg is preparing for a second attempt at the rocket’s inaugural flight from SaxaVord Spaceport in Scotland, European Spaceflight reports. The launch window will open on August 10, the Spaceport said in its announcement.
Microsoft has just four more years to reach its ambitious goal of removing more planet-warming carbon that it produces. But the company’s annual sustainability report, released Thursday, shows it’s moving in the opposite direction, as its 2025 emissions spiked 25% over the previous year.
Despite the troubling increase, Microsoft leaders say they remain committed to the longer-term goal.
“We continue to really be focused around carbon negativity by 2030,” said Melanie Nakagawa, chief sustainability officer, in an interview with GeekWire.
The Redmond, Wash.-based company is the latest tech giant to fall further behind its climate targets as they invest billions of dollars in new, energy-hungry data centers to power the AI boom. Amazon’s carbon footprint jumped 16% last year, while Google’s greenhouse gas emissions swelled 18%.
The report also shows how much energy use drove that increase, with Microsoft’s total electricity consumption growing by 24% last year.
In total, Microsoft produced 20 million metric tons of carbon dioxide equivalent in 2025, which would have been roughly 34 million metric tons without carbon reducing initiatives including purchasing clean electricity and sustainable fuels, Xbox console efficiency and Surface device decarbonization. The reduced number puts the company’s footprint roughly on par with the total emissions of Panama or Lithuania.
In addition to data center expansion, Nakagawa said, the carbon increase was also driven by Microsoft’s decision to stop buying unbundled, short-term renewable energy certificates, or RECs — a mechanism companies can use to quickly lower their reported emissions for a given year. Microsoft is instead prioritizing longer-term initiatives with bigger impact, she said.
The challenge Microsoft wants to answer, she said, is how to take a “portfolio approach” that spans carbon dioxide removal, carbon-free electricity, sustainable materials, and fuels — addressing all of them together rather than in isolation.

Where Microsoft made gains
The annual report highlighted areas of success. That includes:
Matching its electricity consumption worldwide with clean energy sources.
For the first time, replenishing more fresh water globally than it withdrew, making important progress on its 2030 goal of being water positive across operations.
Achieving 92% reuse and recycling of decommissioned cloud servers and components for the second consecutive year.
Reaching a total of 40 gigawatts of clean power purchase agreements across 26 countries, with 19 gigawatts currently online. (Forty gigawatts is roughly enough power to serve 30-40 million typical U.S. homes at once.)
Scrutiny over recent moves
Microsoft’s sustainability disclosures come after a series of announcements and news reports that have raised concerns among climate advocates.
Last month, Microsoft and Chevron announced an agreement to build a natural gas facility in Texas with a 2.67 gigawatt capacity, providing dedicated electricity to the tech company for 20 years.
In May, Bloomberg reported that Microsoft was considering scaling down or scuttling a pledge to match its electricity use with carbon-free power around the clock by 2030.
In April, the New York Times reported that Microsoft was pausing future purchases of carbon removal credits, after years as the market’s top buyer.
Nakagawa said the company has not canceled any removal projects, though she did not provide specifics about new purchases going forward. “We’re just continuing to take a hard look at each of the deals that are coming through,” she said, and looking for “credible opportunities to scale.”
Asked about Microsoft’s commitment to purchasing clean energy 24/7 — an approach that would eliminate reliance on coal- or gas-powered energy when wind and solar aren’t available — Nakagawa declined to confirm it. “We still are looking towards opportunities around carbon-free electricity,” while focusing on the 2030 carbon negative goals, she said.
As to the natural gas deal, the chief sustainability officer said Microsoft has also contracted to purchase 4.7 gigawatts of renewable power in Texas alone and that the company evaluates its energy investments as part of a broader mix.
Looking for efficiencies elsewhere
Even as data centers remain the prime driver of Microsoft’s rising energy use and emissions, the company points to other steps aimed at reducing the environmental footprint of the facilities.
That includes increasing the use of lower-carbon steel and concrete and incorporating mass timber into data center buildings. And In the past year, Microsoft has added a seventh Circular Center — one of several facilities worldwide where the company recycles and reuses electronics from data center operations.
Microsoft is also working with developers to use AI models more efficiently and build right-sized products. AI agents can review, test and improve code so it uses less energy when it runs, Nakagawa said.
“I definitely think there’s an opportunity here,” she said.

While investors spent much of the spring concerned that frontier AI models from companies like Anthropic and OpenAI would consume the software industry, Dave Clark was closing a funding round for exactly the kind of enterprise software those models are supposedly going to replace.
Auger, the supply chain technology startup founded in Bellevue, Wash., by the former Amazon executive, has raised $50 million in Series B funding led by Eclipse, with existing investor Oak HC/FT also participating in the new round.
The round brings total funding to $150 million for the company, which has grown to about 130 employees and counts Meta’s virtual and augmented reality division, sports merchandise giant Fanatics, and consumer products maker Kimberly-Clark among its customers.
Clark’s view is that general-purpose AI can generate insights but can’t handle deeply specialized domains like running a supply chain. Making financial and operational decisions and executing them at the scale of big companies requires systems built on strong supply chain expertise — what Auger calls its ontology, essentially a detailed map of how supply chains actually work.
“Many a pure technology company died on the hill of supply chain over the last decade,” said Clark, the company’s CEO, in an interview this week. “You really need to understand the complexity and the contextual requirements.”
Auger sits on top of a company’s existing systems — ERP, warehouse management, transportation management, and demand planning tools — and unifies the data into a single operating layer. Rather than replacing those systems, it connects them, using AI agents and traditional optimization models to make decisions and execute them automatically, as much as possible.
For example, in a recent demo at the company’s Bellevue office, Clark showed how the system would handle a supplier missing a delivery commitment when there isn’t enough product to go around. Auger identifies the shortfall, determines which customers get priority, reallocates inventory, and pushes the updated plan back to the company’s existing systems.
Most supply chain software, Clark said, generates alerts and waits for a person to act. Auger is designed to make routine decisions on its own and flag the exceptions for human review.
“We’re not really a tool,” he said. “We’re really the new employee.”
At Fanatics, the sports merchandise company, Clark said about 85% of decisions in the process Auger manages are happening autonomously, with a goal of reaching the mid-90s soon. In addition to the customers it has named so far, Clark said another eight to 10 companies are in contract negotiations or pilot programs.
Clark spent 23 years at Amazon, rising to lead the company’s worldwide operations and later its worldwide consumer business. He left in 2022 and became CEO of Flexport, the freight forwarding startup, but that tenure lasted less than a year amid a turbulent period for the company.
He launched Auger in 2024 with a team that includes Leigh Anne Clark, his wife, who serves as co-founder and president of the company’s fashion and beauty division, focused on an industry Clark describes as one of the most wasteful supply chains outside of groceries.
Clark moved back to the Seattle area from Texas to tap the region’s talent pool, and raised a $100 million Series A from Oak HC/FT. The company quickly assembled a C-suite drawn heavily from Amazon’s senior ranks, along with leaders from Johnson & Johnson, Microsoft, and Salesforce, spanning supply chain operations, AI, data science, and product development.
In March, Auger was named a premier supply chain partner on Microsoft Fabric, the tech giant’s data platform. Auger’s product is built on Azure, and Microsoft sales reps can earn commission on Auger deals. Clark said the partnership has generated engagement but is still early.
Clark said Auger went out for the Series B early, before the company needed it, to avoid the distraction of fundraising during what he expects to be a busy fall of customer onboarding.
With the investment, Eclipse partner Jiten Behl joined the Auger board, which also includes Clark, president and CFO Alex Ceballos, and Oak HC/FT’s Matt Streisfeld.
Auger hasn’t disclosed revenue or other financial metrics, but Clark said the valuation was roughly double the level set by Auger’s initial round. “We didn’t shoot for the crazy astronomical valuation,” he said. “We sat at a place that we felt really comfortable with.”
That pragmatic approach extends to how Auger operates. In Bellevue, the company works out of an office it subleased after Microsoft vacated the space. Auger kept the desks, monitors, and chairs the tech giant left behind, furnishing its new offices for next to nothing.
But Clark’s ambitions for the company are anything but modest. He said Auger’s goal is to have half of U.S. GDP flowing through its platform by 2030, with revenue exceeding $1 billion.
“That requires a pretty steep curve to get there,” he said. “We’re not playing small.”

Amazon’s carbon footprint jumped 16% last year after several years of little or no increase. The company emitted nearly 80.9 million metric tons of carbon dioxide equivalent in 2025. By comparison, that’s slightly higher than the nation of New Zealand’s emissions.
Amazon disclosed its climate-related data in its most comprehensive sustainability report to date, which includes a breakdown of its carbon sources, water use and other environmental impacts.
Not surprisingly, energy use showed the biggest rate of increase in the 2025 carbon tally as Amazon and other tech companies are working to rapidly expand their data center capacity to meet AI computing demand.
For the first time since 2019, the company also reported an uptick in its “carbon intensity” — a measure of how much carbon was emitted relative to each dollar of revenue. Amazon has promoted this metric as a sign that it can decouple its growth from its climate impacts.

Despite emissions moving in the wrong direction and ongoing data center-driven challenges, the Seattle-area company remains committed to its pledge of net-zero carbon emissions by 2040.
When it comes to that goal, “I remain confident and optimistic in the overarching vision and the long-term progress we continue to make toward it,” said Kara Hurst, Amazon’s chief sustainability officer, in the foreword to the company’s annual report.
The report highlights areas of success that include:
Data center efficiency: Amazon’s data centers are 9% more efficient than the public cloud average and 30% more efficient than on-premises data centers at directing energy toward computing rather than cooling, lighting or overhead.
Data center water use: Amazon is seven times more efficient in its water use than the industry average thanks to its use of air cooling at most sites, most of the year.
100% clean energy overall: For the third year running, Amazon matched its company-wide electricity use with an equivalent volume of purchased clean energy, although it technically still draws on fossil fuels for some of its energy.
Electric vehicle fleet: It has the largest corporate EV fleet in North America, with more than 52,700 delivery vans worldwide. It’s halfway to meeting its 2030 goal of 100,000 EVs.
The company also reported improvements in reducing packaging and plastic use in delivered items; increasing use of low-carbon building materials in data center construction; and progress toward becoming water positive at its data centers, meaning it aims to replenish more water to communities than it uses.
The Amazon-backed Climate Pledge — an effort to get other organizations to commit to net-zero carbon emissions by 2040 — has grown to 656 signatories after adding 107 companies this year. It marks a notable increase at a time when companies are growing quieter about climate commitments, with some stepping back from earlier goals.
But the surge in data center investment shows little sign of slowing, which will keep complicating Amazon’s path to lower emissions. CEO Andy Jassy said Amazon expects to spend a record $200 billion in capital expenditures this year, including “AI, chips, robotics, and low-Earth orbit satellites.”
Not all reactions to that buildout have been positive — even within the company. Members of Amazon Employees for Climate Justice this month testified before the Seattle City Council in favor of data center requirements for renewable energy and labor protections, though Amazon doesn’t operate any data centers within city limits.
In response to the sustainability report, the employee group was critical of the increased emissions and accused the company of pressuring carbon accounting standards bodies — including the Greenhouse Gas Protocol and the Science-Based Targets Initiative — to adopt weaker rules.
More than 1,000 employees have signed an open letter drafted last year criticizing Amazon’s “warp-speed approach” to its AI development, the group added.
In the report, Amazon CSO Hurst acknowledged that AI-fueled advances could catalyze sustainability solutions or slow progress toward climate goals.
“But what alternative do we have,” she said, “but to continue to invest, learn, and move forward to try to solve one of the world’s most challenging issues?”
