Back‑to‑back GSLV‑Mk III successes restore ISRO’s launch confidence
Summary
- ISRO successfully launched two missions consecutively using the heavy‑lift GSLV‑Mk III (also called LVM3) from Satish Dhawan Space Centre.
- The first flight placed the EOS‑07 Earth observation satellite (≈1,300 kg) into a Sun‑synchronous orbit, while the second deployed the GSAT‑7A communication satellite (≈2,250 kg) into Geostationary Transfer Orbit.
- Both launches demonstrated reliable performance of ISRO’s indigenous cryogenic upper stage and reinforced self‑reliance in high‑capacity launch capability.
- The twin successes came after a series of setbacks with earlier GSLV flights, helping restore national pride and attracting commercial launch interest.
- These missions pave the way for future heavy‑payload projects such as Chandrayaan‑3 and Gaganyaan crewed missions.
