Heli Greus, the mission’s product assurance and security supervisor, is overseeing checks that embrace excessive noise and vibrations to simulate launch circumstances, and a thermal vacuum take a look at, during which Hera will face the acute temperature and different fluctuations that it’s going to expertise in area. If it passes, Greus would be the final particular person to signal the probe off for launch. However, she says, in each launch marketing campaign, there are at all times surprises.
