On August 10th, 2023, Roscosmos’ Luna-25 mission launched from the Vostochny Cosmodrome atop a Soyuz-2 rocket. This mission was the first lunar mission to launch from Russia since the 1970s and would be the first Russian lander to touch down in the South-Pole Aitken basin. This mission was part of Roscosmos’ partnership with China to develop an International Lunar Research Station (ILRS) in the region by 2030. Unfortunately, Russia announced on Saturday, August 19th, that the lander spun out of control and crashed into the surface.
According to the Roscosmos statement, mission controllers lost contact with the craft at 11:57 AM GMT (07:57 AM EST; 04:57 AM PST) after the craft entered its pre-landing orbit. A soft landing was originally planned for Monday and would have been the first time a non-Soviet mission reached the lunar surface. Originally named the Luna-Glob lander, the first of three that would explore the Moon’s southern polar region, the agency decided to change the name to Luna-25 to establish continuity with the Soviet program. As Roscosmos explained on the mission website:
“[D]uring the operation to transfer to the pre-landing orbit, an abnormal situation occurred that did not allow the maneuver to be performed with the specified parameters. According to the results of the preliminary analysis, due to the deviation of the actual pulse parameters from the calculated ones, the automatic station switched to an off-design orbit and ceased to exist as a result of a collision with the lunar surface.”

Roscosmos also indicated a special inter-departmental commission had been established to investigate the reason for the failure. According to Anatoly Zak, the creator and publisher of RussianSpaceWeb (who has been following the mission and posting regular updates), the flight control systems were rumored to be at fault. As he published on August 20th:
“According to one rumor [that] surfaced on August 20, the Onboard Flight Control System, BKU of the lander mishandled the so-called variable thrust controller (privod regulyatora tyagi), which manages the operation of the propulsion system on Luna-Glob. Around the same time, the [official] Russian media quoted IKI scientist Natan Eismont as saying that [the] problems with the spacecraft had been discovered well before the fatal orbit-lowering maneuver, which would have to be postponed to deal with the problem.”
Zak also related a subsequent statement made by Roscosmos Director General Yuri Borisov earlier today, which was also reported by Russian newspaper Moskovsky Komsomolets and Radio Free Europe. All sources confirm that Borisov announced that an engine failure was to blame after it fired for 127 seconds instead of the planned 84 seconds. The failure is a rather significant blow to the Russian space program, which has experienced several setbacks since the beginning of the war in Ukraine, including the termination of its agreement with the ESA to launch the ExoMars 2022 mission and its planned withdrawal from the International Space Station (ISS).
The mission was also intended to raise Russia’s profile in space since the previous Russian-built mission that went to the Moon was the Luna-24 lander in 1976, nearly 50 years ago. Hoping to pick up where their Soviet counterparts left off, Roscosmos initiated the program in 1999 after two years of delays caused by the Russian financial crisis. By the late 2000s, Russia made significant progress, thanks in part to international cooperation and contribution from JAXA and China. This program also served as a pathfinder for the Phobos-Grunt mission, which failed in 2011when its upper-stage engines failed to ignite.
Luna-25 was to be followed by two more robotic landers that would explore the South Pole-Aitken Basin and scout locations and resources for the future ILRS – a program created in response to the Artemis Accords. This failure underscores Russia’s decline as a space power since the days of the Space Race and delivered a blow to

The 10 Best Backpacking Packs of 2024
By Michael Lanza
Backpacks come in many sizes and designs for a reason: so do backpackers. Some of us need a pack for moderate loads, some for heavy loads, and others, increasingly, for lightweight or ultralight backpacking. Some prefer a minimalist pack, others a range of features and access. Everyone wants the best possible fit and comfort, and almost everyone has a budget. But no matter which type of backpacker you are, this review covers the best packs in each of those categories.
Each of my picks for the 10 best backpacking packs stands out for different reasons. I also point out two excellent packs for kids and small adults (at the bottom of the Gregory Paragon/Maven review). My judgments draw from many thousands of miles and more than three decades of backpacking and a quarter-century of testing and reviewing gear—including the 10 years I spent as the lead gear reviewer for Backpacker magazine and even longer running this blog. Few reviewers have lugged as many packs around the backcountry as me.

I’m confident at least one of these packs will be perfect for you—plus you’ll find the best prices for them through the affiliate links to online retailers below. Purchasing gear through my affiliate links supports my work on this blog. Thanks for doing that.
I’ve listed the pack reviews below in order by weight because that’s the metric that most defines and influences a pack’s design and functionality. The ratings admittedly tend to favor more-featured packs, which are heavier, and that may not meet your needs; use the ratings as a comparison with packs of similar weight. The pack you ultimately choose may depend partly on weight, but also on design and on your budget. Each pack review in this article links to that pack’s complete review at The Big Outside.

Hike the World’s Most Beautiful Trail: The Alta Via 2
By Michael Lanza
Hiking toward a mountain pass named Furcela dia Roa, on the first day of my family’s weeklong, hut-to-hut trek on the Alta Via 2 in northern Italy’s Dolomite Mountains, we stopped in an open meadow of grass and wildflowers overlooking a deep, verdant valley in Puez-Odle Natural Park. Across the valley loomed a wall of cliffs topped by jagged spires, like a castle a thousand feet tall. I looked at our map and back up at the stone wall before us, puzzled. After a moment, I realized: We have to get over that wall.
Scanning the vertiginous earth before us, I eventually picked out the trail snaking across the head of the valley and making dozens of switchbacks up a finger of scree, talus, and snow leading to the lowest notch in that wall: the Furcela dia Roa, the pass we had to cross.

It was our first encounter with a lesson that would repeat itself many times over the course of our week of hiking on the Alta Via 2: These mountains are so steep and rocky that the trail often traverses ground that, from a distance, looks impassable without ropes and climbing gear.
But in reality, my family, including our young kids, were perfectly comfortable with the exposure, we never

An AI Simulated Interactions Between Different Kinds of Advanced Civilizations
The possibility for life beyond the Earth has captivated us for hundreds of years. It has been on the mind of science fiction writers too as our imaginations have explored the myriad possibilities of extraterrestrial life. But what would it really be like if/when we finally meet one; would it lead to war or peace? Researchers have used a complex language model to simulate the first conversations with civilisations from pacifists to militarists and the outcomes revealed interesting challenges.
The first radio transmissions were made in 1895 and since then the signals, however weak have been leaking out into space. The first intentional transmission out into space was the Arecibo message of 1974 that was sent toward the globular cluster M13 22,180 light years away. That means the signal won’t arrive there for about another 22,131 years! During this time of course, all the signals have been leaking out but the further they travel, the weaker they get. Its likely then that any signals out to a distance of about 100 light years is likely to be so weak as to not be detectable.

It would be so easy to be dragged into other areas of debate about aliens but it feels useful to set the scene of how difficult it will be to make contact or rather, how likely it may be. Assume then, that in some way, we do find ourselves making communication with an alien civilisation. Just how that conversation goes has been modelled by a team led by Mingyu Jin from Northwestern University.
The team used a new artificial intelligence framework known as CosmoAgent to simulate the interaction based upon the unique Large Language Model (LLM). The system uses a Multi-Agent System to enable modelling among a diverse range of civilisations. The civilisations have the ability to choose their own character traits from hiding, fighting or collaborating. This dynamic environment allows for a plethora of outcomes from alliances forming, adherence to rules to rivalries to how a civilisation might respond to an unforeseen event.
Diversity and conditions for life were also inherent in the modelling using transition matrices to analyse how civilisations might grow and change over time. This natural progression of an intelligent life form would inevitably mean ethics, morals, beliefs and sciences would develop along a varied path. These different frameworks would hugely effect just how such a civilisation might respond to alien contact.
There are limitations to the research though, largely from an Earth-centric bias developing the language model. The use of mathematics and algorithms to compute responses and outcomes may not cover the full spectrum of inter-civilisation responses. After all, we cannot even distill our own emotional responses down to a set of algorithms. Add in a speculative set of principles of an alien civilisation, of which, we have no evidence or experience to draw upon.
It is hoped that future research can address these obstacles and develop better models of inter-civilisational interaction. Taking into account a broader range of ethical paradigms and decision making processes to provide a more realistic simulation of just how first contact may just play out.
