The launch will take off from Cape Canaveral Air Force Station in Florida, and will use a Dragon cargo capsule that SpaceX has already flown twice previously, first in 2014 and then again in 2017.
"Standing down today due to upper altitude winds and high winds at sea creating dynamic conditions around the Of Course I Still Love You droneship", SpaceX's tweet explains. The first RELL unit was launched in 2015 while the second was launched in 2019 as a back-up. "We launch data balloons to measure actual winds". It also needs to be bought outside the space station using the Dextre robotic arm- used to perform maintenance operations.
However, over its lifetime, the space station has accumulated occasional small ammonia leaks at its joints, often as a result of micrometeroids.
For example, RiTS and RELL's capabilities could be employed to detect potential leaks occurring from future human habitats on lunar and other planetary surfaces, as well as the Lunar Gateway.
The leak detectors until now have required 12 hours of preparation time in space, once brought through airlocks, to be usable.
The new place of residence for these robots was developed by the Satellite Servicing Projects Division at NASA's Goddard Space Flight Center in Maryland in collaboration with the Johnson Space Center in Houston. Twenty seeds will be sprouted or grown out.
During Wednesday's mission, the Dragon capsule will separate from the rocket nine minutes after liftoff, according to SpaceX, which projects that it will attach to the space station on December 7.
When the Falcon 9 is finally able to fire its Dragon cargo spacecraft into the sky, it will be carrying a whole bunch of awesome gear.
