First contact application

*Edited entry from 04/05*
After the removal of the NI payload from the tower and its transfer to the Clean Room in CB, I applied First Contact to the AR side of the mirror (the CP and the rear baffle was dismounted and separated from the payload). Tomorrow morning (05/05/26) a second application in the HR face is planned.

melo, majorana, naticchioni, ricci - 20:56 Tuesday 05 May 2026 (69071)

Today, after the dismountling of the two baffles in front of the mirror (HR side) by L. Naticchioni e M. Ricci, I applied First Contact on the payload HR surface.

Before applying the FC, I inspected a bit the surface and I could spot many dust particles (Figs. 1 to 2). I could also find a big scratch on the upper left side of the mirror (Fig. 3). Moreover, it was possible to observe by eye the big point absorber found previously with the thermocamera (VIR-0106A-26) roughly at 9 cm to the right wr.t. the center of the mirror (Fig. 4). Measuring it on the picture, a slight more precise estimation is 8 cm, instead of 9 cm.

Figs. 5 to 7 show the FC application process and the completed work.
