SpaceX Will Use Tesla Car Batteries to Power Movable Wings for Starship Re-Entry
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 a space elevator from the Earth to Geostationary orbit. The moon spaceline would be longer …
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 of the re-entry temperatures. Transpiration cooling will be added wherever we see erosion of the …
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 using a network of low-frequency radar to detect and locate stealth aircraft. The B-21 will …
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 at the joins. Roger Holt shows what all of the pieces will look like when …
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 massive metal resource then it would make lunar colonization and the industrial development of space …
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 easily entangled, plus scientists can turn that interactivity on and off easily so that individual …
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 the University of Pennsylvania approaches this challenge from a number of directions. Recently, the lab …
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 spacecraft to get close as one solar radii (430,000 miles) from the Sun’s surface. This …
