Chronology
Mission timeline
Launch
Chandrayaan-1 launched on a PSLV-XL from Sriharikota
NASA NSSDCA reports 00:52 UT (06:22 local time). The event timestamp is normalized to UTC.
Orbit insertion
Chandrayaan was put into a 7502 x 504 km lunar polar orbit
The page dates this within an unbroken sequence following the launch it prints as 2008-10-22, but does not repeat the year. The year is derived from that sequence, not read.
MoonDeployment
The Moon Impact Probe was released
The page dates this within an unbroken sequence following the launch it prints as 2008-10-22, but does not repeat the year. The year is derived from that sequence, not read.
MoonImpact
The Moon Impact Probe hit the lunar surface near the Moon's south pole
The page dates this within an unbroken sequence following the launch it prints as 2008-10-22, but does not repeat the year. The year is derived from that sequence, not read.
MoonMilestone
Chandrayaan-1 orbit raised from 100 km to 200 km
NASA PDS records the orbit raise on May 19, 2009. Its date precision is day-only.
MoonLoss of contact
Contact was lost abruptly
The page prints "28 August" and "31 August" without a year, and prints no year later than the 2008 launch anywhere. 2009 is derived as the only August falling within the mission after launch.
MoonMission end
ISRO announced the mission had been officially terminated
The year is derived as for the loss of contact; the page does not print it.

Trajectory record
Time-dependent navigation trajectory
Source states place the model at the selected time. Reconstructed flight, estimates, predictions and historical mission plans are identified by interval; gaps remain visible.
Source records and sampling assumptions are retained with the repository data. Model attitude and surface appearance are illustrative.
