Same-day delivery comes to space, as Impulse promises satellite transport in hours, not months

techcrunch.com Aria Alamalhodaei 2025-09-23 17:07:15

Amazon made same-day delivery the benchmark on Earth. Impulse Space is pitching a similar concept for satellites bound for geostationary orbit about 22,000 miles above Earth, compressing what is typically a months-long transit into a matter of hours. In the span of a week, the in-space propulsion startup announced a trio of deals aiming to unlock geostationary orbit (GEO) for commercial and defense users. That includes a demonstration mission with defense contractor Anduril planned for 2026; a

Rivian breaks ground on $5B Georgia factory ahead of construction in 2026

techcrunch.com Sean O'Kane 2025-09-24 01:03:23

Rivian has officially broken ground on its long-planned factory near Atlanta, Georgia, which will one day allow the company to make as many as 400,000 of its next-generation electric vehicles per year. The company held a shovel ceremony on Tuesday where CEO RJ Scaringe was joined by Georgia officials, including Governor Brian Kemp. But, as TechCrunch first reported in July, the company is still eyeing the first quarter of 2026 for an official construction start-date, with vehicle production sta

Ex-Google X trio wants their AI to be your second brain — and they just raised $6M to make it happen

Three former Google X scientists aim to give you a second brain virtually — not in the sci-fi or chip-in-your-head sense — but through an AI-powered app that gains context by listening to everything you say in the background. Their startup, TwinMind, has raised $5.7 million in seed funding and released an Android version, along with a new AI speech model. It also has an iPhone version.

Geothermal is too expensive, but Dig Energy’s impossibly small drill rig might fix that

techcrunch.com Tim De Chant 2025-10-06 01:00:00

On a farm near Manchester, New Hampshire, I was recently treated to a gusher of dirty water, not exactly the sort of thing that most startups will show a reporter. But for Dig Energy, the mud is a feature, not a bug, of its compact drilling rig. The startup, which has been operating in stealth for the last five years, developed the water-jet drilling rig in an effort to make geothermal heating and cooling so inexpensive that it will displace fossil fuel boilers and furnaces.

Two men fell gravely ill last year; their infections link to deaths in the ’80s

The four cases were tied together not just by their shared location but also by the bacterial strain; whole genome sequencing showed the bacteria causing all four infections were highly related, suggesting a shared source of their infections.

Superhot geothermal energy could unearth big power boost for the AI era

Geothermal energy has been used for thousands of years, powering heating systems as early as the 14th century. It's getting a big upgrade. Beyond geothermal, there's superhot geothermal, which uses ultra-deep drilling to access extremely hot rocks, extracting 5 to 10 times more power per well. Quaise Energy, a Massachusetts-based startup, is in the market developing the technology, which involves an electromagnetic beam that vaporizes rock.

Once upon a time, if you wanted to play Neo Geo games, it took serious financial investment. The original Neo Geo AES (Advanced Entertainment System) home console launched at $650 in 1991, equivalent to about $1,535 in 2025. Games would sell for around $200, around $472 today. The hook, for an emerging underground of gamers, was that the AES was identical at a hardware level to manufacturer SNK's MVS (Multi Video System) coin-op cabinets, meaning games played at home were indistinguishable from

The Pigeon River Is Perched, Which Is Geologically Bad News (2020)

While “soon” can be a very relative term in geology, there is most definitely a good answer to the question. At Canton, North Carolina, the headwaters of Hominy Creek, a French Broad River tributary, are VERY close to capturing the Pigeon River. In human terms, this is still probably a long way off, but it is most certainly geologically “imminent.” The
