Key Details at a Glance
| Item | Detail |
|---|---|
| Test | CM-SM separation |
| Location | VSSC, Thiruvananthapuram |
| Subsystems checked | Avionics, inertial navigation, heat shields, umbilical shield, pyrotechnic devices |
| First uncrewed mission (G1) | Targeted for 2026; no date in the report |
What was tested
The tests simulated the integrated assembly with heavy instrumentation, including severing multiple umbilical connections. ISRO said they showed robustness and shock survivability of the subsystems.
Why separation matters
Before re-entry, the crew module separates from the service module through precisely sequenced pyrotechnic and jettison events. Any failure here would endanger a crew, so validation is critical. Read about Gaganyaan.
What is not stated
The report gives no test dates or counts, and no specific G1 launch date. Do not treat any date you see elsewhere as confirmed until ISRO announces it. More in our ISRO coverage.
What Is Not Confirmed
- The G1 launch date is not confirmed in the report.
