After missing multiple deadlines, India’s ambitious Gaganyaan human spaceflight programme is finally edging closer to a crucial milestone. According to the latest update, the first uncrewed Gaganyaan mission (HLVM3 G1/OM1) is now likely to lift off before March 2026, marking a major step toward India’s goal of sending astronauts to space.
This mission will test the entire end-to-end spaceflight sequence — from launch to splashdown — using an unpressurised crew module, ensuring systems are safe before humans fly.

🛰️ What This Mission Will Demonstrate
The upcoming uncrewed flight is designed to validate every critical phase of a human space mission. The human-rated launch vehicle will place the spacecraft in low Earth orbit, after which the crew module will safely re-enter Earth’s atmosphere, deploy parachutes, and perform a controlled splashdown — followed by recovery.
This test is essential before astronauts can be onboard.
⏳ Why Gaganyaan Has Faced Delays
First announced by Prime Minister Narendra Modi in 2018, Gaganyaan was initially targeted for 2021, coinciding with India’s 75th Independence anniversary. However:
- COVID-19 disrupted supply chains
- Manufacturing and system integration faced setbacks
- Revised timelines in FY22, FY23, and FY24 were missed
Even though ISRO committed to multiple missions in FY25 and FY26, the schedule has remained fluid.
🔧 Systems Already Tested & Certified
Despite the delay, ISRO has made significant technical progress:
- Crew Escape System motors tested for high & low altitudes
- Crew Module Thermal Protection System validated
- 10-parachute system successfully tested, including air-drop trials
- Half-humanoid robot performance verified
- Communications, onboard computers & vibration tests completed
- Safety items like survival kits and dosimeters certified
These milestones ensure astronaut safety once crewed missions begin.
🗓️ What Lies Ahead in the Gaganyaan Calendar
The programme has expanded from 3 missions to 8 missions — including:
- 6 uncrewed missions
- 2 crewed missions
- Launch of the first module of the Bharatiya Antariksh Station

❓FAQs
Q1: Why is the first Gaganyaan mission uncrewed?
Uncrewed missions test safety, re-entry, and recovery systems to ensure astronauts face minimal risk during crewed flights.
Q2: When will Indian astronauts finally go to space?
If tests succeed, ISRO aims for the first crewed Gaganyaan mission by late 2027 or early 2028.
