The XRS insert is at 1.3 Kelvin, and all the valves are set for launch. The XRS insert is full of helium, and is connected to a vacuum pump. We will pump on the helium until its temperature drops from 4.2 Kelvin to 1.4 Kelvin, the temperature it will have in orbit. After the helium temperature reaches 1.4 K., we will top off the insert with a little more helium, and close the valves for launch. We completed a spacecraft functional test after the launcher tests.
All systems are still go for launch.
Today the launcher was tested. The launcher team opened the big door on the tower and rotated the rocket out. The rocket is fully assembled. On January 31 it was rolled from the assembly building to the launch tower, where it was lifted up and bolted to the top of the second stage. The nose fairing is attached.
