Revolutionary Rover Tech Tames Extreme Moon Temperatures
A team from Nagoya University invented a heat-switch device for lunar rovers to withstand the Moon’s extreme temperatures. The technology optimizes thermal control, alternating between cooling and insulating, facilitating longer missions with less energy.
Astronauts navigating the moon’s terrain in a vehicle contend with not only the perils of zero gravity and potential crater falls, but also drastic temperature swings. The moon’s climate ranges from searing highs of 127°C (260°F) to bone-chilling lows of −173°C (−280°F).
Team from Nagoya University in Japan developed a heat-switch device designed to enhance the durability of lunar rovers. Their collaborative research with the Japan Aerospace Exploration Agency was featured in the journal Applied Thermal Engineering.
Water on Earth is older than the Sun, which reshapes our understanding of everything
Scientists found that water in our solar system is likely billions of years older than the sun by studying the protostar V883 Orion, linking water from the interstellar medium to our solar system.
This research suggests that water in our solar system was formed long before the sun, planets, and comets, indicating that planetary systems.

The cryptoterrestrial hypothesis: A case for scientific openness to a concealed earthly explanation for Unidentified Anomalous Phenomena
Recent years have seen increasing public attention and indeed concern regarding Unidentified Anomalous Phenomena (UAP). Hypotheses for such phenomena tend to fall into two classes: a conventional terrestrial explanation (e.g., human-made technology), or an extraterrestrial explanation (i.e., advanced civilizations from elsewhere in the cosmos). However, there is also a third minority class of hypothesis: an unconventional terrestrial explanation, outside the prevailing consensus view of the universe. This is the ultraterrestrial hypothesis, which includes as a subset the “cryptoterrestrial” hypothesis, namely the notion that UAP may reflect activities of intelligent beings concealed in stealth here on Earth (e.g., underground), and/or its near environs (e.g., the moon), and/or even “walking among us” (e.g., passing as humans). Although this idea is likely to be regarded sceptically by most scientists, such is the nature of some UAP that we argue this possibility should not be summarily dismissed, and instead deserves genuine consideration in a spirit of epistemic humility and openness.
China’s ‘artificial sun’ achieves breakthrough in nuclear fusion
Chinese scientists have made a groundbreaking milestone in nuclear fusion. They have announced a major achievement in discovering an advanced magnetic field structure “for the first time in the world” using the Huanliu-3 (HL-3) tokamak, also known as China’s “artificial sun.”
The discovery is the result of the first round of international joint experiments conducted on the HL-3 tokamak, a project that opened to global collaboration at the end of 2023.
Voyager 1 Returning Science Data From All Four Instruments
Most distant spacecraft, #Voyager1, is now returning data from all four science instruments for the first time following a technical issue last November.
NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and status of the spacecraft. On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data.
The four instruments study plasma waves, magnetic fields, and particles. Voyager 1 and Voyager 2 are the only spacecraft to directly sample interstellar space, which is the region outside the heliosphere — the protective bubble of magnetic fields and solar wind created by the Sun.
