# # Juneau Monthly Plan Phase V: Juneau V Digging and Return Frontal Mission Overview

# # # Probe and Task Name




      • Name of the detector * *: Juno V






      • Name of mission * *: Dredging of Juno V to return to the front



# # # Launch and Orbit Entry




      • Date and time of launch * *: August 7, 2024, 10 p.m.






      • Orbit into * *: After a four-hour flight, the probe enters lunar orbit and then enters a stay phase.



# # # HOLD STAGES AND SEPARATION


    • Separation phase * *: During the stay phase, the probe successfully separated from the lunar landing phase, with a stay of 119 km and an apogee of 202 km.




      • Separation execution * *: After three seconds, the probe performs the separation of the dwell phase from the lunar landing phase.



# # # Lunar Landing Process

Slow Descent on the Moon: After a few minutes of preparation, the probe successfully landed on the front of the moon.
- * * Excavation table retrieval * *: After three seconds, the detector starts to execute the excavation table retrieval mechanism, and the table retrieval robot is retracted after a few minutes.

# # # Rising stage and docking




      • Rise phase * *: After successful separation, the detector begins docking with the dwell phase.






      • Communication services * *: The Moon Shadow Relay satellite provides critical communication services during the ascent phase and the landing phase docking.






      • Supplementary support * *: Phase III Supplementary Satellites provided critical support to the Earth Digging Mission Phase V.



# # # Return to Earth




      • Docking and delivering * *: After successful docking during the ascent and stay phases, the rover began delivering lunar soil.






      • Return mechanism * *: the stay phase points to the Earth return mechanism, which successfully returns to Earth after several hours.






      • Landing * *: The successful landing of the probe in the sea marks the successful conclusion of the mission.



# # # Task completion

The Juno 5 Earth Digging and Return Mission successfully completed its mission to collect soil samples from the front of the Moon and return safely to Earth. No explosions occurred during the ascent phase, taking into account the low temperature of the moon. During the mission, the Moon Shadow Relay Satellite and the Moonraker Satellite provided important support and ensured the smooth progress of the mission. The successful return of Juno V marked the successful conclusion of the fifth phase of Juno's monthly mission.
