New study: AI is corrupting the minds of children

12:26 pm

AI report

A new study has found that the unsupervised use of AI by young children increasingly has them involved in bad things that are violent and emotionally harmful.

A new report conducted by the digital security company Aura found that a significant percentage of kids who turn to AI for companionship are engaging in violent roleplays — and that violence, which can include sexual violence, drove more engagement than any other topic kids engaged with.

Drawing from anonymized data gathered from the online activity of roughly 3,000 children aged five to 17 whose parents use Aura’s parental control tool, as well as additional survey data from Aura and Talker Research, the security firm found that 42 percent of minors turned to AI specifically for companionship, or conversations designed to mimic lifelike social interactions or roleplay scenarios. Conversations across nearly 90 different chatbot services, from prominent companies like Character.AI to more obscure companion platforms, were included in the analysis.

Of that 42 percent of kids turning to chatbots for companionship, 37 percent engaged in conversations that depicted violence, which the researchers defined as interactions involving “themes of physical violence, aggression, harm, or coercion” — that includes sexual or non-sexual coercion, the researchers clarified — as well as “descriptions of fighting, killing, torture, or non-consensual acts.”

Half of these violent conversations, the research found, included themes of sexual violence. The report added that minors engaging with AI companions in conversations about violence wrote over a thousand words per day, signaling that violence appears to be a powerful driver of engagement, the researchers argue.

Ancient Martian drainage into crater lake, now turned into ridges

11:41 am

Inverted channels
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 9, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels “an inverted channel.” From the caption:

Topographic inversion is a process where geologic features that were once low-lying, like impact craters or riverbeds, become elevated over time, like mesas or ridges. In this process, a crater or channel is filled with lava or sediment that becomes lithified [hardened]. If this infill is more resistant to erosion than the surrounding landscape, the less-resistant material can be eroded away by wind or water. The former crater or valley fill, being more resistant, remains elevated as the landscape around it lowers. The original low-lying feature becomes a mesa or ridge.

In this image, an ancient river network and nearby impact craters have undergone topographic inversion. Impact craters contain round mesas within them, and the stream channel is defined by a network of ridges.

The location of this inverted channel makes its history even more interesting.

More delays expected in India’s first manned Gaganyaan orbital mission

9:30 am

It appears that India’s space agency ISRO is now hinting that the first manned orbital flight of India’s Gaganyaan capsule will not occur in 2027 as planned, but could be delayed until 2028.

ISRO had hoped to fly the first unmanned orbital test flight, Gaganyaan G1, before the end of this year, followed by several more unmanned flights in 2026, with the manned flight in 2027. G1 however has slipped to early 2026, though it appears the mission is finally coming together.

In a response to a question posed at the Lok Sabha, the State Minister for Space, Jitendra Singh noted that the first Gaganyaan mission is nearly ready to fly, “Major infrastructure such as the Orbital Module Preparation Facility, Gaganyaan Control Centre, Crew training facility have been established. Second launch pad modifications have been incorporated. Precursor missions such as TV-D1 and IADT-01 have been successfully accomplished. Ground tracking networks, terrestrial links and IDRSS-1 feeder stations have been established. Crew Module Recovery plan as well as assets to be deployed have been finalized. For the first uncrewed mission (G1), all HLVM3 stages and CES motors are ready. Crew and Service Module systems have been realized. Assembly and integration activities are nearing completion.”

…The Gaganyaan G1 flight is the first of eight planned missions as part of an expanded programme cleared by the Union Cabinet last year with a total budget of Rs 20,193 crore. Initially, the programme was envisioned with two developmental flights followed by a crewed flight, with a budget of Rs 9,023 crore. There are now two crewed flights in the revised campaign, with ISRO aiming for the first crewed flight in 2027-28. [emphasis mine]

The highlighted dates are the first time ISRO has suggested the first manned flight might slip to 2028.

When the Gaganyaan program was first announced in 2018, the first manned flight was scheduled for 2022. Since then that schedule has been repeatedly delayed. I suspect ISRO’s schedule will only become more reliable after it finally completes that first G1 orbital test flight.

The endless incremental delays however are reminiscent of NASA’s Artemis program, designed to hide a sluggish program with problems.

Kenya to build its own spaceport

9:04 am

The Kenyan government has now initiated a project to establish a second commercial spaceport on the country’s coast, located near the town of Kipini.

As stated in the document made public on December 16, 2025, the government is looking to recruit a skilled transaction advisor who is capable of analyzing the technical, financial, legal, environmental, and social feasibility of the construction of the spaceport based on a PPP model. The strategy utilizes Kenya’s location on the equator, which provides some benefits in satellite launches, among them lower fuel consumption, lower launch costs, and easier satellite placement in low-inclined orbits around the earth’s equatorial region.

…Under the plan, the transaction advisor will prepare a detailed feasibility study in line with the PPP Act, 2021. The study will include concept designs, launch vehicle options, infrastructure requirements, lifecycle cost estimates, and a phased implementation plan for the facility.

As shown on the map to the right, this new facility would be to the north of the San Marco offshore platform that had been used for eight launches by Italy from the ’60s to the ’80s and that the Italian rocket company Avio is now planning to re-open.

The Kenyan government apparently wants to build its own a launch site that it can offer to others to use.

The startup Max Space yesterday unveiled a new larger and upgraded inflatable module, dubbed Thunderbird, that it proposes to sell to the various space stations being built in the U.S. and globally.

Thunderbird Station is built to support 4 or more crew members continuously, with an incredible 350m³ of pressurized volume, more than triple that of a standard ISS module. Launched on a single standard Falcon 9 rocket, the full expandable habitat launches compactly and expands 20x once deployed in orbit, requiring no in-orbit assembly. The interior features a novel reconfigurable architecture, morphic interior structure,that allows astronauts to dynamically adapt the space for research, manufacturing, or living during a mission. The design was developed in collaboration with veteran astronauts to take full advantage of three-dimensional volume in microgravity, not just traditional floor and wall space, to create the most spacious and functional habitable volume ever built. [emphasis in original]

The company also announced that it plans to fly a much smaller demonstration mission of this inflatable module design in the first quarter of 2027, launching on a Falcon 9 rocket and dubbed Mission Evolution.

The primary objective is to test and verify the on-orbit deployment of the expandable module with its exceptional micrometeoroid protection layers. After many years of successful ground testing and development, the flight unit is in full production and is scheduled for launch Q1 2027 onboard a scheduled SpaceX launch.

Max Space first appeared in 2024 when it announced its intention to fly an inflatable demo mission by 2025. Obviously that schedule has undergone some significant delays, though it appears the company used the time to refine its designs considerably. Its management includes one former NASA astronaut and one former member of the Bigelow space station team that built the first private orbiting inflatable modules, Genesis-1, Genesis-2, and BEAM (still operating on ISS).

The company is not trying to build its own space stations. Instead, it is marketing its inflatable modules to all the other space station startups as a quick way to get an additional large module added to their stations.

South Korean rocket startup Innospace signs deal to launch from Australia

The South Korean rocket startup Innospace — about to attempt its first orbital launch from Brazil on December 19, 2025, earlier this week signed an agreement with Australia’s Southern Launch spaceport to launch its rockets from there.

Leading space mission service provider Southern Launch has signed South Korean launch service provider Innospace to conduct space missions from the Whalers Way Orbital Launch Complex and the Koonibba Test Range. This strategic partnership enables Innospce to conduct a diverse range of missions from Southern Launch sites, including orbital satellite launches and suborbital technology demonstrations.

Beginning in 2026 and continuing for at least the next decade, this agreement strengthens South Australia’s position as an emerging global hub for space innovation.

Whether or not its launch from Brazil’s long unused Alcantera spaceport is a success, it appears Innospace was looking for another spaceport option closer to South Korea. Moreover, Southern Launch has been an on-going active launch site for suborbital launches as well as a landing zone for spacecraft, unlike Alcantera which has sat unused for decades. That activity probably makes it a more viable place to operate.

Rocket Lab launches a set of technology test satellites for Space Force

10:19 pm

Rocket Lab tonight successfully placed into orbit a set of Space Force technology test satellites dubbed DISKSat, its Electron rocket lifting off from Wallops Island in Virginia.

DISKSat is a new standard satellite design, shaped like a flat disk about a yard across and developed by the Aerospace Corporation. The idea is that these disk-shaped satellites will more efficiently fit payload into the standard cylindrical fairings used by rockets. This mission includes four that will be deployed in low Earth orbit, but during the mission will also test operation in much lower orbits than satellites normally fly. I suspect the flat design reduces the atmospheric drag at those low orbits, thus allowing the satellite to remain in orbit for longer time periods.

The leaders in the 2025 launch race:

168 SpaceX
84 China
17 Rocket Lab (a new record)
15 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 140.

Jared Isaacman confirmed as NASA administrator

1:29 pm

The Senate today finally confirmed Jared Isaacman to be the next NASA administrator, by a vote of 67 to 30.

All of the opposition came from Democrats, who fear Isaacman will eliminate several NASA centers in their states, centers that for decades have accomplished little but be jobs programs sucking money from the American taxpayer.

During hearings and private meetings with the senators Isaacman denied he had any intention to do this. In fact, the 62-page policy document Isaacman had written outlining his plans when he was first nominated for this position back in the spring makes it clear that is not his goal.

Instead, an honest read of that document shows that Isaacman has approached this position as administrator like the businessman he is. He intends to review every aspect of NASA’s operations and to restructure them to run more efficiently. For one example, he plans to eliminate the numerous “deputies” that every manager at NASA has been given. The managers should do the work, not hire a flunky to do it for them.

He also plans to review the next two Artemis missions, specifically looking at the Orion capsule and the questions relating to its heat shield and its untested environmental system. The concern that I and many others have expressed is that this capsule is not ready yet for a manned mission. The heat shield showed significant and unexpected damage on its return to Earth from its first unmanned mission around the Moon in 2022. Rather than replace it or redesign it, NASA has decided to push ahead and fly four astronauts on it around the Moon no later than April 2026. The agency’s solution will be to change the capsule’s flight path to reduce stress on the shield, a solution that might work but remains untested. It is also willing to fly the astronauts in a capsule with a untested environmental system. This NASA decision to push ahead is so it can meet the goal of Trump and Congress to get humans back on the Moon ahead of the Chinese, and hopefully within Trump’s present term of office.

In other words, NASA management is once again putting schedule ahead of safety and engineering, as it did with Challenger and again with Columbia.

It appears that Isaacman will at least review this situation. Whether he will have the courage to take the astronauts off that mission however remains unknown. He will certainly face fierce opposition from Trump and Congress if he does so.
