NASA astronauts got a “pretty awesome” view of SpaceX’s Crew Dragon vehicle docked with the International Space Station during a spacewalk on Friday (June 29).

Astronauts Chris Cassidy and Bob Behnken got the view of a lifetime when they stepped outside the space station to replace the outpost’s old solar array batteries. The star of that view was Endeavour, the SpaceX Crew Dragon spacecraft that delivered Behnken and his fellow NASA astronaut Doug Hurley to the station May 30 on their Demo-2 mission.

Dr. Charles Forsberg observes technological overlap between Molten-Salt Reactor (fission) development and Fusion Reactors due to manufacturing breakthrough of Rare-Earth Barium Copper Oxide (REBCO) Superconducting Magnets onto steel tape.

REBCO superconducting tape enables doubling magnetic fields.

Size of magnetic fusion system for any given power output varies as one over the fourth power of the magnetic field. Higher magnetic fields can shrink fusion system size by an order of magnitude, power density in the fusion blanket increases by an order of magnitude.

Higher power densities in the blanket make it difficult to cool solid blankets. High magnetic fields create large incentives to have a coolant with low electrical conductivity to avoid coolant/magnetic field interactions.

The Chinese government is taking draconian measures to slash birth rates among Uighurs and other minorities as part of a sweeping campaign to curb its Muslim population, even as it encourages some of the country’s Han majority to have more children.

While individual women have spoken out before about forced birth control, the practice is far more widespread and systematic than previously known, according to an AP investigation based on government statistics, state documents and interviews with 30 ex-detainees, family members and a former detention camp instructor. The campaign over the past four years in the far west region of Xinjiang is leading to what some experts are calling a form of “demographic genocide.”

The state regularly subjects minority women to pregnancy checks, and forces intrauterine devices, sterilization and even abortion on hundreds of thousands, the interviews and data show. Even while the use of IUDs and sterilization has fallen nationwide, it is rising sharply in Xinjiang.
