After everyone had put on their spacesuits, the transport vessel began pumping out its air under the system's voiced instructions, reducing the internal pressure to 0.02 standard atmospheres.
Unlike the Hope, these small and medium transport vessels had not been equipped with separate airlocks, considering the need for rapid mass production and cargo capacity. Instead, they evacuated the air from the entire cabin, then replenished it from gas tanks once personnel returned.
The figure of 0.02 standard atmospheres varied according to the planet being landed on. Ross154-4's atmospheric pressure was currently 0.02 standard atmospheres, so the pressure inside and outside had to be equalized before exiting. Otherwise, the moment the door opened, the people inside the transport vessel would be squeezed out by the immense pressure. Anyone with even a little knowledge of physics understood that.
It was simply a matter of human habit, much like how the Hope still used Earth time.
To facilitate the initial work, the landing had been scheduled for morning on this planet, which was three in the afternoon by Earth time. In the planet's own time, it was seven in the morning.
This planet's rotational period was roughly sixty-six hours, so from the moment its star rose in the morning, its daylight lasted approximately thirty-three hours.
Because the planet's various parameters had already been entered into the program, after the personnel landed, the electronic clocks in their hands displayed two times: Earth time and Ross154-4 time.
This was not humanity's first extraterrestrial planetary landing, so all of this was standard procedure. They had done the same thing when landing on Mars and Callisto.
Ross154-4's atmosphere consisted primarily of nitrogen and Carbon Monoxide, accounting for roughly 61.4% and 36% respectively. The remainder was Carbon Dioxide and inert gases.
It was a planet utterly unsuitable for
