The Proba-3 program, ESA's 150-m long formation-flying solar coronagraph takes an important (long-awaited) step in the integration of its two satellites.

- "AMOS recently completed the Optical Head Unit of the Fine Lateral and Longitudinal Sensor (FLLS) for the Proba-3 mission. [...] The Optical Head Unit has now been delivered to Switzerland where it will undergo themal testing. It will then travel to England for calibration testing before being integrated into the spacecraft during spring of 2023."

- "ROB/SIDC [Solar Influences Data Analysis Center of the Royal Observatory of Belgium] has successfully passed the Flight Acceptance Review of its Science Operations Centre for PROBA-3/ASPIICS"

Proba-3 complete: Formation-flying satellites fully integrated, and should now launch early 2024.

Proba-3 has begun thermal-vacuum testing at IABG.
