Saturday, 5th August, 2023 marked a significant
achievement for the Chandrayaan-3 mission as it successfully accomplished the
Lunar Orbit Insertion (LOI) milestone. The Lunar Orbit Insertion (LOI)
procedure was executed by performing a retro-burn at the point closest to the
moon (Perilune) for a duration of 1835 seconds, beginning at 7:12 PM IST from
Mission Operations Complex (MOX), ISTRAC, Bengaluru. This action resulted in
the desired orbit of 164 km x 18074 km.
The upcoming lunar-bound orbit maneuver is
slated for August 6, 2023, between 22:30 and 23:30 Hrs. IST.
Chandrayaan-3's health remains stable,
continuously monitored from the Mission Operations Complex (MOX) at ISRO
Telemetry, Tracking, and Command Network (ISTRAC), along with support from the
Indian Deep Space Network (IDSN) antenna near Bengaluru and assistance from ESA
and JPL Deep Space antenna.
ISRO has successfully placed its spacecraft
into lunar orbit for the third consecutive time, in addition to achieving a
similar feat with Martian orbit insertion.
As the mission progresses, a sequence of
planned maneuvers will gradually lower Chandrayaan-3's orbit, positioning it
over the moon's poles. Following certain maneuvers, the propulsion module will
detach from the lander while in orbit. Subsequently, a series of intricate
braking maneuvers will be conducted to enable a gentle landing in the Moon's
South Polar region on August 23, 2023.
On the accomplishment of successful LOI, ISRO
tweeted,
"Chandrayaan-3 Mission:
“MOX, ISTRAC, this is Chandrayaan-3. I am
feeling lunar gravity 🌖”
🙂
Chandrayaan-3 has been successfully inserted
into the lunar orbit.
A retro-burning at the Perilune was commanded
from the Mission Operations Complex (MOX), ISTRAC, Bengaluru.
The next operation - reduction of orbit – is
scheduled for Aug 6, 2023, around 23:00 Hrs. IST."
