The new lunar space elevator study differs from previous proposal would be anchored on the moon and stretch 200,000 miles toward Earth until hitting the geostationary orbit height (about 22,236 miles above sea level). We do not have materials for …

Tokamak Energy Reaches 24.4 Tesla High Temperature Superconducting Magnets Which Are Key to Nuclear Fusion Plans

Elon Musk indicated that SpaceX will test thin ceramic tiles to protect the Super Heavy Starship from re-entry heat instead of using active transpirational cooling. This will only need to be on 10-20% because the steel alloy could handle most …

The US Air Force is building its first test version of the new next-generation B-21 Raider stealth bomber. The B-21 will have regular stealth against higher-frequency engagement radar and also against lower-frequency surveillance radar. China and Russia have shifted to …

The orbital version of the SpaceX Starship is getting stacked in Texas. Pictures from Maria Pointer show that there seem to be improvements in how each of the ring sections are being constructed. The newest rings appear to be superior …

A large mass of material has been discovered beneath the largest crater on the Moon, the South Pole-Aitken basin, and it may contain metal from an asteroid that crashed into the Moon and formed the crater. If this is a …

There are three major competing Quantum computer technologies for qubits. They are nitrogen-vacancy (NV) centers in diamond lattices, trapped ions, and superconducting qubits. The benefit of trapped-ion systems is that the ions are inherently going to affect one another. They’re …

Map of the Inorganic Metal Nitrides Could Lead to Better Superconductors

The key to harnessing the potential power of quantum systems is being able to create or find structures that allow electron spin to be reliably manipulated and measured, a difficult task considering the fragility of quantum states. Bassett’s lab at …

In 2018 the Parker Solar Probe launched and plans to approach the Sun to within 8.5 solar radii (4 million miles) of its surface. This is seven times closer than any previous mission. Researchers think a new coating could allow …
