ISRO PSLV C-61 Launch Failure

Just recently, ISRO attempted to launch its PSLV C-61 mission, officially named EOS-09. Now, most people only hear about rocket launches in passing, but very few understand why the mission was launched, what its actual purpose was, and how important it truly was.

In this blog, let us break it down for you, in simple terms, but with all the crucial facts. We’ll also explore whether this failure could be a national security concern.

What Was PSLV C-61 and EOS-09 All About?

(PSLV C-61 failure)- On 18th May at 5:59 AM, ISRO launched the EOS-09 satellite aboard the PSLV C-61 rocket. PSLV, or Polar Satellite Launch Vehicle, has been the backbone of many successful Indian space missions. But this time, the mission faced a failure in its third stage.

No, the rocket did not explode. But it failed to reach its intended orbit. Which means the EOS-09 satellite could not reach the position from which it was supposed to function effectively.

So now the question arises – what was EOS-09 supposed to do?

It was an advanced Earth Observation Satellite equipped with SAR (Synthetic Aperture Radar) technology – capable of capturing ultra-clear images of Earth in all weather conditions – clouds, fog, rain, even dense forest cover.

SAR Technology: This Is Not a Camera, It’s a Radar

Unlike traditional satellites that rely on optical cameras, EOS-09 worked on SAR, which uses radio waves to scan Earth. These waves bounce back after hitting the surface, and the satellite constructs highly accurate images, even through clouds or at night.

This is not just useful, it is critical, especially when visibility is low in high-altitude or border regions.

Now ask yourself – if a satellite can provide real-time images even during bad weather or at night, doesn’t that give a strategic advantage?

Absolutely. And that’s where national security comes into the picture.

How EOS-09 Ties into National Security (PSLV C-61 failure)

India shares sensitive and volatile borders with countries like China and Pakistan, especially in regions like Jammu & Kashmir, Ladakh, and Arunachal Pradesh. Troop movement, construction of bunkers or roads – these happen regularly on both sides.

When clouds cover the sky or during harsh winters, traditional satellites struggle. That’s where SAR satellites like EOS-09 become crucial. They provide 24×7 surveillance, regardless of weather.

Did you know? The USA and Russia possess similar SAR tech, but they do not share it with anyone. It’s considered strategic and highly classified.

India developing its own SAR system is not just an achievement; it’s a game-changer.

Military and Satellites: The New-Age Defence Combo

In today’s era, wars are not only fought on the ground, but also in space and cyberspace. Military-grade satellites are now as important as tanks and missiles.

When the USA invaded Iraq, they had live satellite feeds guiding their troops. In the Russia-Ukraine war, both sides are using satellite imagery for real-time military strategy.

So, if India wants to monitor Chinese activity in the Himalayas or detect enemy movement in advance, we need satellites like EOS-09 in orbit.

EOS-09 Was Not Just About Security

While national security was its top priority, EOS-09 also had several civil applications:

• Agriculture monitoring
• Forest mapping and tracking
• Disaster management
• Topographical mapping of difficult terrains

But here’s the twist – while we can buy agricultural data from global agencies if needed, security-related satellite data is never sold. It’s strictly restricted.

So, in the absence of EOS-09, we lose a vital independent surveillance tool.

Should India Be Worried About PSLV’s Failure? (PSLV C-61 failure)

Let’s be honest – this is not the first time a space mission has failed, and it won’t be the last. Even global giants like NASA and SpaceX face similar setbacks.

To date, ISRO has launched 59 PSLV missions, with a success rate of over 90%. That’s remarkable by global standards.

Yes, the failure of PSLV C-61 is disappointing, but each failure teaches scientists more than success ever can. ISRO has already started analysing the issue, and the upcoming missions – like Gaganyaan, NISAR, and Chandrayaan-4 – will incorporate better safeguards and technologies.

Here’s a Question for You:

Should India now aim to become a space superpower like the USA, Russia, or China?

Is it not essential for us to develop and own our technologies, whether in defence, space, or digital infrastructure?

If your answer is yes, then it’s time we support ISRO, not just when it succeeds, but even when it falters. Because the real success lies in learning, rebuilding, and moving forward.
