NASA's planned programs for establishing a permanent human presence on the Moon may represent more than just a technological challenge. According to specialists quoted by Newsweek, long-term living on the lunar surface could cause profound changes in how people think, feel, and interact, given the conditions of isolation, confined space, and distance from Earth.
Although being on the Moon opens new horizons for space exploration and human development, neuroscientists and psychiatrists warn that this experience could subject inhabitants to significant mental health risks, necessitating the development of new adaptation strategies.
NASA has accelerated its plans to create a long-term base near the Moon's South Pole, scheduling the final stage of 'sustainable human presence' on the lunar surface starting in 2032. The agency acknowledges that the psychological difficulties of space missions are a serious issue. NASA notes that isolation and confined spaces can lead to a decline in cognitive and behavioral performance.
While measures taken on the International Space Station (ISS) have largely helped mitigate these risks, NASA warns that missions beyond low Earth orbit will face greater difficulties because traditional astronaut support systems will be harder to implement.
A study conducted by the agency itself and published in November 2024 in the journal Frontiers in Physiology analyzed astronauts who were on the ISS for six months. The results showed that while overall cognitive function remained stable, there were periods of reduced information processing speed, attention, and working memory during the missions.
Psychiatrist and neurobiologist Dave Rubin, author of A Simple Guide to Being Alive, believes that long-term stay on the Moon will place unprecedented pressure on the human nervous system. He told Newsweek that 'long-term lunar residency will challenge the nervous system in one of the most fundamental ways.'
According to Rubin, humans evolved in environments characterized by sunlight, Earth's gravity, natural landscapes, and social interaction. The prolonged absence of these elements can increase the risk of insomnia, anxiety, depression, irritability, and cognitive impairment. The specialist describes space as a 'psychologically cruel' environment conducive to hallucinations, sleep disturbances, and emotional suffering.
Rubin cautions that 'admiration without a sense of belonging can turn into existential vertigo.' He emphasizes that the main problem may not be boredom, but the loss of natural cues that help people feel at home. He added: 'No random reminder of the living world that you are part of something bigger than your own thoughts.' He explains that this is important because the human brain evolved in natural, rhythmic, and diverse conditions rich in movement, sounds, smells, light, and texture.
Rubin compares a lunar settlement to an 'absolute sensory deprivation chamber with a view.' Without climate, animals, changing seasons, or familiar natural sounds, residents may become increasingly dependent on artificial stimuli and more self-focused.
According to Rubin, the effects of gravity go far beyond simple locomotion. The expert explains that balance, posture, circulation, sleep quality, movement, and spatial orientation depend on gravity. Although the Moon has gravity, it is significantly weaker than Earth's.
He asserts that 'over time this can indirectly affect cognitive functions and mood through changes in sleep quality, movement patterns, cardiovascular regulation, inflammation, vestibular processing, and the ingrained sense of body.' He also adds: 'The body evolved on Earth. It remembers Earth, even when the mind tries to leave.'
Matt Grammar, head of clinical counseling and founder of Therapy Training, posits that a lunar colony will eliminate many external stimuli that help people regulate mood and form their identity. In his view, factors such as climate, vegetation, natural sounds, and the alternation of days play an important role in psychological balance.
Grammar argues that prolonged confinement can contribute to anxiety, depression, irritability, emotional numbness, and decision-making problems. Unlike astronauts on the ISS, residents of a permanent base must create a functional society, not just complete a temporary mission. 'On the Moon, the mind may fight less against fear than against the emptiness of monotony,' he noted.
For the specialist, people need constant change. 'It's very simple, we humans need variety. This can be through climate, seasons, nature, our community, and daily activities and routines. Without this, a lunar resident will have to provide artificial signals—otherwise the mind may begin to perceive the environment as emotionally empty.'
Zand, a psychiatrist and CEO of Anywhere Clinic, believes that the hardest test will be maintaining human connections. She stated: 'The most difficult experience of living on the Moon is the danger of prolonged confinement and separation.'
Comparing future lunar colonization to polar expeditions and space missions, Zand notes that people need diversity and elements considered normal to thrive. 'Our bodies adapt and adjust to new circumstances, but there is no guarantee that our psyche will follow suit.'
In her opinion, future lunar settlements will need to recreate aspects of earthly life to help residents 'feel connected to something greater than themselves.' Despite the challenges, experts believe that humans possess a huge capacity for adaptation. However, according to Dave Rubin, this adaptation may lead to the emergence of a new human identity. He predicts that a permanent presence on the Moon 'will ultimately create a new type of human identity—people who are biologically human but culturally shaped by distance from Earth,' which may be 'exciting in the short term, but also strange, lonely, and spiritually destabilizing.'
According to the neuroscientist, the main psychological question for future colonists will be defining their own existence. 'Do lunar colonists feel like pioneers expanding human capability, or exiles separated from the only living world that created them?' As NASA advances its plans for maintaining a permanent presence on the Moon, experts believe that the greatest challenge may not only be ensuring the survival of the inhabitants but also preserving their sense of humanity in an environment completely different from Earth.
Linus Torvalds, known as the creator of Linux, stated in a project discussion list to defend the incorporation of artificial intelligence (AI) into kernel development. He clarified that the project does not have an 'anti-AI' stance.
Torvalds argued that AI should be seen as just another support tool for kernel development, similar to other tools already used in the project. According to him, this technology should only be used when it demonstrates real utility, and not by following trends.
He acknowledged that AI can present challenges, citing the fact that it occasionally generates 'embarrassing bugs'. This observation was contextualized by Torvalds, who had complained during the development of Linux kernel 7.1 about the excessive volume of failure reports generated by AI tools. He emphasized that his criticism was not aimed at AI itself, but rather at the disproportionate use of these tools, which overloaded developers with notifications of problems that had already been resolved or were not a priority.
In general terms, Torvalds reinforced that he does not oppose the use of AI in software development, as long as its use is consistent and its limitations are not neglected. He stated that decisions within Linux are based on technical merit, not fear of new technologies.
In his message, he declared that Linux is not an anti-AI project and that those with objections can choose to create a fork or abandon the project. Torvalds concluded that AI is undeniably a useful tool, and that the kernel community works with open source code aiming for superior technology, not for religious reasons.
As part of a new scientific and agricultural initiative, South Africa has launched the 'Rooibos in Space' program. For the first time for South Africa, rooibos seeds will be sent to the International Space Station (ISS) in October.
This program combines research in space biology with practical education in science, technology, engineering, and mathematics (STEM). The launch of the program took place on Thursday at the Parkland College Innovation Centre. The event gathered representatives from academic circles, education, agriculture, government, and the developing space economy.
The concept of the program belongs to the South African Rooibos Council (SARC) and is implemented jointly with MaxIQ Space with the support of the South African National Space Agency (SANSA). The project links rooibos to the growing international interest in studying plant biology in space and developing sustainable off-Earth agricultural systems.
During the program, rooibos seeds will be delivered to the ISS in October, where they will remain for several weeks under the influence of microgravity and cosmic radiation. After returning to Earth, the seeds will be planted alongside control samples for a comparative analysis that will study germination, growth, resilience, and yield.
Students from seven schools in the Sedderberg region, as well as students from Parkland College, will participate in the experiments after the seeds return. The experiment will be conducted by students from the Sedderberg region, which is the homeland of rooibos. Working with local farms, students will collect and analyze data as part of a structured scientific investigation. A parallel experiment at Parkland College will provide additional comparative data.
The rooibos study complements the extensive body of research on plants in space. Experiments aboard the ISS have already shown that crops such as lettuce can grow in microgravity conditions, and the study of peas and soybeans has provided insight into how plants react to changes in gravity and environmental stress factors. These results contribute to progress in both future space food systems and enhancing agricultural sustainability on Earth.
SARC Director, Dawie de Villiers, noted that the project reflects the industry's commitment to innovation, education, and applied research. He emphasized that this project places rooibos within a broader scientific context where plant biology, space exploration, and education intersect, while also highlighting the importance of investing in scientific literacy and skill development for future researchers.
School students will undergo an expanded STEM education program that will introduce them to space science, plant biology, and sustainable agriculture, aligning with curricula and linking classroom learning to practical scientific application.
Judi Sandrock from MaxIQ Space stated that the goal of the initiative is to improve students' access to authentic scientific learning. She noted that the value of the project lies in providing students with the opportunity to familiarize themselves with real research processes related to space science, offering a structured way to develop scientific thinking and data analysis skills.
Furthermore, students from across South Africa will be able to participate in the design of the official 'Rooibos in Space' mission badge in July and August. Bertram Loriston, Deputy CEO for Curriculum Management at the Western Cape Education Department (WCED), stressed the importance of cross-sector partnerships for expanding STEM opportunities.
Thandile Vuntu, Head of Science Engagement at Germinus for SANSA, stated that space science is increasingly integrating into everyday applications. He added that such initiatives help raise awareness of the skills needed for future participation in this sector and align with national priorities for skills development and strengthening South Africa's position in new scientific fields.
DKIM (DomainKeys Identified Mail) is a security mechanism that uses a cryptographic digital signature to certify the authenticity of an email. This standard ensures that the message was actually dispatched by the declared domain and that it has not been modified during its journey to the recipient.
To operate, the system requires a pair of keys: a public key, which is registered in the domain's DNS, and a private key, used to sign the header of each transmission. When the destination server receives the content, it uses the public key to verify the signature, thus confirming the integrity of the email.
This technology protects brands and institutions against phishing threats and enhances the sender's credibility with service providers. By preventing legitimate communications from being classified as spam, the protocol ensures a safer and more reliable flow of information for important messages.
DKIM applies an encrypted digital signature stamp to emails, informing receiving servers that the message is genuine and unaltered. This validation protects the identity of a company or organization, hindering schemes like spoofing and phishing, as it prevents fraudsters from impersonating the legitimate domain.
Additionally, this method improves message delivery and prevents valid sends from ending up in the junk folder. In collaboration with SPF and DMARC, the technology helps strengthen the sender's reputation and optimize email traffic.
The operation of DKIM begins with generating a pair of cryptographic keys in the email server settings. The public key must be entered into a specific DKIM record in the domain's DNS so that recipients can consult it.
At the time of sending, the server creates a unique security code based on the content of each email. This information is then encrypted using the private key and attached to the message header as the DKIM signature. Upon arrival, the receiving server queries the sender's DNS to obtain the corresponding public key. Using this key, it decodes the header and recalculates the security code to compare the data.
If the codes match, the system confirms that the message was not altered in transit and allows it entry. This procedure validates the authenticity of the send, helping the message bypass spam filters and gain the trust of security systems.
Manual configuration of DKIM is not necessary for personal and free accounts, such as common Gmail accounts, as the providers themselves perform the authentication automatically. However, the feature is mandatory for corporate emails that use a proprietary domain in services like Google Workspace or Outlook. The process involves creating a public key in the provider's panel and adding it to the website's DNS settings.
The main benefits of DKIM include integrity assurance, where the signature acts as an inviolable seal, ensuring that no content or link has been tampered with. It also blocks forgeries, as scammers without access to the private key cannot create valid signatures, preventing phishing attacks.
Authenticated messages improve their reputation with security filters, facilitating their passage to the reader and reducing the chance of going to spam. Furthermore, DKIM protection remains valid even when the email is forwarded by third parties. Finally, it serves as a fundamental basis for more advanced security policies, such as DMARC.
The limitations of DKIM include the technical complexity in key generation and DNS record updates, which can be laborious in corporate environments with multiple systems. Any automatic alteration in transit, such as footers inserted by antivirus software, can invalidate the signature, making a legitimate email appear suspicious.
It is important to note that the protocol only validates the message, without determining a specific action in case of failure; for that, it depends on DMARC support. Moreover, DKIM does not prevent replay attacks, allowing a criminal to resend a previously signed valid email. Lastly, it does not guarantee the sender's reliability, only the message's integrity.
While DKIM seals each email with a unique cryptographic signature verified via a public key in the DNS, DMARC establishes strict guidelines, such as rejecting or quarantining messages that fail SPF or DKIM checks. DMARC integrates these protocols into the visible sender address, protecting the inbox. SPF, on the other hand, functions as a public list in the DNS, specifying which servers and IPs are authorized to send emails on behalf of the domain, thereby blocking sends from unauthorized sources.
Unlike encryption, which scrambles all content to ensure absolute confidentiality, DKIM is an authentication method that acts as a digital seal in the header, proving the origin and integrity of the message, but without hiding the text.
