Солнце достигало пика активности в пределах 11-летнего цикла.
The Sun has reached a maximum period of activity. Expect more aurora, NASA says.
We can expect additional aurora displays and potentially more impacts to technology over the next year or two, according to NASA and the National Oceanic and Atmospheric Administration.
Между тем, с взлетного стола уже сняли вернувшийся бустер, установили новый и успели протестировать на нем двигатели. Интересно, когда собираются следующий полет делать.
Часов через 6 должен вернуться 8-й Дракон, возвращение которого 8 раз откладывали из-за непогоды. Среди членов экипажа должен по плану находиться также русский космонавт.

Тут рассказывают особытиях этой недели. Вначале о прогрессе российской программы (модуль Орел) и китайской программмы, вернее китайской частной компании LandScape, которая впервые и раньше SpaceX запустила вывела на орбиту спутники с помощью ракеты на метановом двигателе.
The issues he mentioned included the July Falcon 9 launch failure when the second stage failed to perform a second burn, grounding the rocket for about two weeks. Another upper stage engine anomaly on the Falcon 9 launch of the Crew-9 mission Sept. 28 during a deorbit burn also grounded the vehicle, with the exception of one mission, for two weeks. Falcon 9 launches were also briefly halted in August when a Falcon 9 booster was lost attempting a droneship landing.
“When you look at these recent incidents over the last handful of weeks, it does lead one say that it’s apparent that operating safely requires significant attention to detail as hardware ages and the pace of operations increases,” he concluded. “Both NASA and SpaceX need to maintain focus on safe Crew Dragon operations and not take any ‘normal’ operations for granted.”
Launched in 1969, just a few months after humans first set foot on the Moon, Skynet-1A was put high above Africa's east coast to relay communications for British forces.
When the spacecraft ceased working a few years later, gravity might have been expected to pull it even further to the east, out over the Indian Ocean.
But today, curiously, Skynet-1A is actually half a planet away, in a position 22,369 miles (36,000km) above the Americas.
Orbital mechanics mean it's unlikely the half-tonne military spacecraft simply drifted to its current location.
Almost certainly, it was commanded to fire its thrusters in the mid-1970s to take it westwards. The question is who that was and with what authority and purpose?
SpaceX’s new Starship rocket far exceeds projected maximum noise levels, generating a sonic boom so powerful it risks property damage in the densely populated residential community near its South Texas launch site, new data suggests.
Starship, as tall as a 30-story building, is so large that it generates 10 times as much noise as the Falcon 9 rocket that SpaceX now uses to get cargo and astronauts to orbit, the new data shows. SpaceX plans another test this week.
For residents of South Padre Island and Port Isabel, which are about six miles from SpaceX’s launch site in South Texas, the noise during the October test flight was the equivalent of standing 200 feet from a Boeing 747 plane during its takeoff, said Kent L. Gee, an independent acoustics engineer who conducted the monitoring.
