No one had ever launched a commercial nuclear satellite. SpaceX and City Labs just did it with Transporter-17

SpaceX has launched the first commercial nuclear satellite in history. This is BOHR, a CubeSat developed by the City Labs company, and has been completely successfully placed into orbit as part of the Transporter-17 mission, from Elon Musk’s space company. This is intended to demonstrate that the use of nuclear energy to power vehicles, satellites and space probes is not just a matter for large public agencies. Tritium to make history in space. Betavoltaic Orbital High-Reliability (BOHR) is a CubeSat in which a nuclear reaction similar to the one that has been used for decades takes place. to propel the Voyager probes through space. Although there is a difference. While these obtain energy from the heat generated by the disintegration of plutonium, in this case the beta particles released by the disintegration of tritium are used. Afterwards, these They are transformed into electricity through a semiconductor. The use of tritium is an advantage, as it emits much less radiation, making its pre-launch handling safer. Speaking of the launch. This nuclear satellite was one of the 81 payloads that were part of the Transporter-17 mission on July 7. A Falcon 9 rocket of SpaceX propelled all of them into space after launching from said company’s platform, located at the Vandenberg base. Just 50 minutes after launch, each of the payloads, including BOHR, were placed into their respective orbits. Two possible uses. The use of nuclear energy in space is something that has been studied a lot for two reasons. Firstly, because it can be useful for ships that are going to travel very far, so that they cannot carry enough fuel on board. It is precisely the reason why this energy source was used with Voyager probes. On the other hand, nuclear energy is useful when solar energy is not an option. The Voyager probes traveled a long way from the Sun, but you don’t have to go that far either. The lunar south pole It is constantly in shadow, so in the future, when the Artemis bases are built there, nuclear power could be very necessary. A project with many supports. The development of BOHR was funded under a contract from the United States Department of Defense. In addition, it is the first nuclear mission that has received nuclear launch approval from the Federal Aviation Administration, specifically under the Presidential National Security Memorandum 20 of Donald Trump. Therefore, despite being a private project, it has received all the public support necessary for its implementation. That, along with its inclusion within a SpaceX mission, shows that there are many powerful eyes on this project. It’s just a test. In fact, BOHR has been used to prove that this way of obtaining nuclear energy is viable in space and that it can be used commercially. Currently, the satellite is in orbit, ready to launch the test reaction. However, the CubeSat uses solar panels to obtain energy for its own operation. The next step could be a satellite that exclusively uses tritium decay. For now, this first proof of concept has marked what may be the future of many commercial space missions.

Airra Labs has thought just the opposite

We have become accustomed to the mouse being a mature, almost closed tool, as if there was little room left to change what we do with it every day. Its design has improved a lot: it has gained precision, better materials, more capable sensors and, in some very specific models, such as gaming ones, a number of buttons that years ago would have seemed excessive. But just look at how we scroll through a page to find a surprising continuity: a finger that pushes, the content that goes up or down and a gesture so assumed that any alternative is born with an obvious disadvantage. First he has to convince us that the habit was not untouchable. At my desk, this gesture is almost always solved by a Logitech MX Master 3Sa mouse designed for productivity that relies on a very precise and comfortable physical wheel to scroll through long documents or endless pages. In the backpack, however, I have a Magic Mousewhich eliminates that wheel and turns the top of the mouse into a touch surface. Both seem natural to me in different contexts, and perhaps that is why this proposal draws attention: it does not try to polish what is known, but rather to change the movement that we take for granted. A mouse to rotate, not to scroll That’s where the Rotary Mouse comes in, Airra Labs’ proposal to change a very specific part of our relationship with the computer. The idea is not to add more buttons or improve the usual wheel, but to replace it with a rotary mechanism integrated into the mouse itself. According to the companythe user places their finger on that piece and turns it as if it were a dial, with tactile clicks and direct control over the speed and direction of movement. The goal is to move more fluidly through web pages, documents, spreadsheets, code or timelines. On paper, Airra Labs does not focus its speech only on speed. The company claims that the Rotary Mouse can scroll up to 2.5 times faster than a conventional mouse, but it accompanies that figure with another equally important idea: more control. Its rotating wheel includes tactile clicks, supports traditional vertical scrolling and, according to its creators, allows you to move with precision by turning slowly or advance quickly by increasing the pace. The ergonomic part comes with the so-called ROM, acronym for range of motion, a range of motion exercise with which Airra Labs says it wants to reduce the tension accumulated in the fingers. When you see it in images, the first thing that appears is not a certainty, but a strange sensation. This circular movement of the finger is not very similar to the gesture we make with a traditional wheel or sliding on a touch surface like that of the Magic Mouse. It may seem uncomfortableperhaps because we have spent years training our hand for something else, but that visual impression has an obvious limit: it does not replace the real experience of use. And that is precisely what is interesting. Sometimes an idea seems strange not because it is poorly stated, but because we do not yet have the necessary habit to understand it. Where the proposal can gain meaning is in those jobs in which moving is not a secondary action, but a constant part of the task. Airra Labs mentions very specific examples on its website: video timelines, long spreadsheets, long documents, code, JSON files and long web pages. In all these cases, the problem is not only getting to a point sooner, but doing so without losing precision along the way. It even proposes the use of the rotary wheel as a kind of small steering wheel for driving simulators. There is, however, a necessary caution: the Rotary Mouse arrives in the launch phase through a financing campaign and we have not been able to test it yet, so it is advisable to keep a certain distance before drawing conclusions. Airra Labs now places its estimated price between 49 and 109 dollarsa fork that will depend on the version chosen. Even so, the idea has something valuable even if it later has to pass the most important test: it reminds us that even the most established gestures can be put back on the table.

Thousands of people were following the Iran war with satellite images from Planet Labs. So the US has closed it

The satellite images are a key piece for modern military intelligence. They are the eyes on the ground, they allow you to see where the enemy is, their supply routes, their defenses and plan more precise attacks. For the public, they are the direct window to the battlefield and in the Iran conflict there are two companies that are deciding whether to let us watch or not, one is American and one is Chinese. Guess who is who. The Planet Labs blackout. It is a satellite earth imaging company based in San Francisco. It operates a network of more than 200 satellites that allows them to provide global coverage of the planet, recording more than 300 million square kilometers of images collected every day. Planet Labs images have been key in conflicts such as the ukrainian war or the escalation of tensions between China and Taiwan. However, when it comes to a conflict in which the US is the protagonist, things change. The restriction: On March 6, Planet Labs announced a four-day delay in the publication of its images of the Middle East, a measure they described as “temporary and intended to protect personnel and operations.” The controversy: What is striking is that the delay affected countries with a US military presence (Iraq, Kuwait, Saudi Arabia and the United Arab Emirates), while the images of Iran continued to be published almost in real time. This unleashed reviews on Xcalling it a measure to manipulate public opinion by hiding the damage to US bases, while only showing the damage caused to Iran. The extension: The company recently extended this delay to 14 days. According to statements to Reutersseek to ensure that your data “does not contribute in any way to attacks against allied, NATO personnel or civilian populations.” Mizar Vision. Given the Planet Labs blackout, there is a company that continues to offer satellite images almost in real time. It is about Mizar Vision, a Chinese startup based in Shanghai that does not have its own satellites, but instead purchases commercial images. Its value is that it applies an AI layer that detects, geolocates and tags military assets in almost real time and publishes them on Weibo, the Chinese social network. There is an account on X with the same name, but the company has already confirmed that It is not an official account. Attack prediction. Two days before the attack on Iran, Mizar Vision published images which showed planes lined up on the runway of the Diego García base, signaling that the attack was imminent. They were high resolution images in which details such as the model of the aircraft could be distinguished. They also identified other key infrastructures such as the anti-missile systems that the US has in Jordan and the al-Udeid base in Qatar, all of them. attacked by Iran days later. Mizar Vision is the open window to the battlefield, but we can all look, the Iranian army too. The shadow of Beijing. The images prior to the attack were shared by accounts with links to Chinese People’s Liberation Army. They count in The Country That analysts wonder to what extent the Chinese government is encouraging the publication of such detailed images, with such precision and in real time in a context of such tension. The company continues to publish images of US military movements in the region.
