Rocket Report: European rocket reuse test delayed; NASA tweaks SLS for Artemis II

Welcome to Edition 8.11 of the Rocket Report! We have reached the time of year when it is possible the US government will shut down its operations at the end of this month, depending on congressional action. A shutdown would have significant implications for many NASA missions, but most notably a couple of dozen in the science directorate that the White House would like to shut down. At Ars, we will be watching this issue closely in the coming days. As for Artemis II, it seems to be far enough a

Keeping SSH sessions alive with systemd-inhibit

In my Home Lab network I use my desktop for most of my development. Since it’s a desktop and not a server it abides by the power policy setting I have selected. This works great unless I’m working a remote session from anything else such as my laptop, cell, etc. My usual workflow is just an ssh session with tmux, where I wake up the system by issuing a Wake on LAN (wol) from an always on server. After the typical timeout around 30 mins the system goes to sleep which drops the session and forces

Here’s How to Deflect a Dangerous Asteroid Without It Totally Backfiring

In September 2022, NASA deliberately crashed a spacecraft into an asteroid, successfully altering the space rock’s trajectory. The orbital shove demonstrated an asteroid deflection technique that could come in handy if a massive rock were headed in Earth’s direction. As it turns out, however, deflecting a potentially threatening asteroid is only half the battle. Striking an asteroid for deflection purposes could send it back on a collision course with Earth, merely delaying the planet-shatterin

Show HN: Semlib – Semantic Data Processing

Semlib Semlib is a Python library for building data processing and data analysis pipelines that leverage the power of large language models (LLMs). Semlib provides, as building blocks, familiar functional programming primitives like map , reduce , sort , and filter , but with a twist: Semlib's implementation of these operations are programmed with natural language descriptions rather than code. Under the hood, Semlib handles complexities such as prompting, parsing, concurrency control, caching,

You’re a slow thinker. Now what?

I'm not a quick witted person. In fact, I’ve always been worried about my brain’s slow processing time. But recently, I've realised that slow processing time is not as much of an issue as I thought it was. And even if I was wrong about that, I still think I’d do better for myself by leaning into it, instead of spending energy trying to fight it. In this essay, I want to talk about some ways I've been able to skirt around my lack of quick wittedness! To get what I mean by slow processing time,

Osteo-Odonto-Keratoprosthesis

Medical procedure for the eye Medical intervention Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery,[1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.[2] After removal, a longitudinal lamina is cut from the tooth and a hole is drilled perpendicular to the lamina. The hole is then fitted with a cylindrical lens. The lamina is grown in the patients' ch

Evidence of Ancient Asteroid Impact and Tsunami Found in North Carolina

Around 35 million years ago, a small asteroid traveling at 40,000 miles per hour (64,373 kilometers per hour) struck Earth, crashing into the Atlantic Ocean near the modern-day town of Cape Charles, Virginia. The approximately 3-mile-wide (5-kilometer) object created a large impact crater that’s buried half a mile beneath Chesapeake Bay. Hundreds of miles south of the crater, scientists have found new evidence of the asteroid impact and the tsunami that followed the shattering event. Hidden ben

Rocket Report: Russia’s rocket engine predicament; 300th launch to the ISS

Welcome to Edition 8.10 of the Rocket Report! Dear readers, if everything goes according to plan, four astronauts are less than six months away from traveling around the far side of the Moon and breaking free of low-Earth orbit for the first time in more than 53 years. Yes, there are good reasons to question NASA's long-term plans for the Artemis lunar program—the woeful cost of the Space Launch System rocket, the complexity of new commercial landers, and a bleak budget outlook. But many of us w

NASA Says This Martian Rock Holds Potential Signs of Life. Here’s What Must Happen Next

For four years, NASA’s Perseverance rover has searched for possible signs of ancient life on the surface of Mars. It has found myriad interesting features in its travels, including a rock with strange spots, discovered inside Mars’ Jezero Crater. Dubbed “Cheyava Falls,” the 2024 discovery immediately caught the attention of scientists on Earth, as its spots indicated it may hold a potential biosignature—a sign of life. The rover went to work. The bot analyzed the rock’s composition and surface

This American Influencer Traveled to Australia to Film Himself Tackling Crocodiles. Australians Aren’t Happy

Following the rocket’s success, SpaceX founder and CEO Elon Musk is now confident that the massive vehicle will begin flying payloads to space in 2026. During an interview with the All-In Podcast, Musk explained how an upgraded version of Starship will reach orbit by next year and demonstrate full reusability of the Super Heavy booster and its upper stage. “Unless we have some very major s

Has Perseverance found a biosignature on Mars?

Last year, we reported on the discovery of an intriguing arrow-shaped rock on Mars by NASA's Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. Granted, this was not slam-dunk evidence of past life on Mars, and the results were preliminary, awaiting peer review. But it was an intriguing possibility nonetheless. Now further analysis and peer review are complete, and there is a new paper, published in the journal Nature

NASA to Make Major Announcement About Martian Rock Sample on Wednesday. Here’s How to Watch

In July 2024, NASA’s Perseverance rover extracted a rock core from the edge of Neretva Vallis, a river valley cut into the Martian surface by water rushing into the Jezero Crater billions of years ago. This mysterious rock caught the attention of scientists on Earth, as its features may reveal clues about possible ancient life on the Red Planet. At 11 a.m. ET on Wednesday, September 10, NASA will host a press conference to discuss the analysis of the sample, dubbed “Sapphire Canyon,” and the su

Congress and Trump may compromise on the SLS rocket by axing its costly upper stage

There are myriad questions about how NASA's budget process will play out in the coming weeks, with the start of the new fiscal year on October 1 looming. For example, the Trump administration may seek to shut off dozens of science missions that are either already in space or in development. Although Congress has signaled a desire to keep these missions active, absent a confirmed budget, the White House has made plans to turn off the lights. Some answers may be forthcoming this week, as the Hou

The New Math of Quantum Cryptography

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them will doom most forms of cryptography. Several years ago, researchers found a radically new approach to encryption that lacks this potential weak spot. The approach exploits the peculiar features of quantum physics. But unlike earlier qua
