ISS现在是full house，一大堆人在上面

”Six spaceships are parked at the space station including Boeing's Starliner spacecraft, the SpaceX Dragon Endeavour spacecraft, the Northrop Grumman resupply ship, the Soyuz MS-25 crew ship, and the Progress 88 and 89 resupply ships.”

现在停靠的龙飞船是送crew8上去的，过几天space X 会送crew9上去，crew8 回来。那两个宇航员以前就在空间站长期工作过，现在计划接替两个crew9的工作，跟crew9一起回来
