When the satellite eventually makes the jump to space—on a rocket out of New Zealand—it’ll be outfitted with a number of instruments provided by the European Space Agency to monitor its integrity.

“The first item we’re embarking is a pressure sensor, which will allow us to identify the local pressure in onboard cavities in the hours and days after launch into orbit,” said Riccardo Rampini, a materials scientist at the ESA, in an agency press release.

“This is an important factor for the turn-on of high power systems and radio-frequency antennas, because small amounts of molecules in the cavity can potentially cause them harm.”.
