# An Expedition to Sriharikota (ISRO)

> “Twenty years from now you’ll be more disappointed by the things you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream, Discover.”

> **\-Mark Twain / H Jackson Brown Jr** (Author Uncertain)

These words propelled a bunch of engineering students from [SUIIT](https://suiit.ac.in/), Burla to step out of the safety nets for an expedition to **Satish Dhawan Space Centre (SDSC),** the heart of Indian Space Mission, situated on the island of **Sriharikota** in the SPS Nellore District of Andhra Pradesh State.

It’s the **satellite launching center** of the premier Indian Space Agency [**ISRO**](https://www.isro.gov.in/). Visiting an ISRO space center in 2019, its **golden jubilee year**, wasn’t less than any utopian moment for us!

Due to its nature of carrying out **secret missions** throughout the year, they can’t afford the interference of trespassers in their pursuit of social welfare. So only through having a strong network with any ISRO insiders, access can be granted to this secure zone for a **very limited time.** Aadhaar card and college ID along with formal attires were our saviours for that day!

### Sullurupeta: The Gateway of Sriharikota!

On the **7th January** of **2019,** the journey to Sriharikota began with a bus trip from the nearby Sullurupeta railway station in Andhra Pradesh.

The presence of this space center over an island on the Bay of Bengal with the **Pulicat Lake** nearby enriched with the green lushes of flora makes it a catchy spot for nemophilists.

The group comprising 40 students and 4 teachers after a light breakfast at the Aryabhatta guest house present inside the campus moved ahead to explore this exotic center along with the **instructor** Ashok Kumar Meher, who then served as the **technical officer** at SDSC. Before that, we were instructed to **leave behind our digital gadgets.**

The bus stopped near an **auditorium** to watch some introductory videos on this space center and recall the contributions of **Dr. Vikram Ambalal Sarabhai**, the Father of the Indian space program and **Prof. Satish Dhawan** after whom this center is named.

### **Mission Control Centre**

It's a **circular establishment** inaugurated back in 2012 by then Hon’ble President of India **Mrs. Pratibha Devisingh Patil**, turned our next stoppage. It hosts multiple display screens to showcase **real-time satellite data** and a set of computer chairs meant to be occupied by the top-level scientists during the launching preparation days.

There’s also a **VVIP audience gallery** that hosts the **Prime Minister of India** and other elites during a launch, which is televised on **Doordarshan**.

The instructor Mr. Meher guided us through every curious question shot at him with due care of the **professional secrecy** he had to maintain as an insider.

I was captivated by the name plates displaying **Mission Director** & **Vehicle Director** present over two of the monitors inside MCC. As we were informed, these two persons were referred to as the **prominent bosses** of a space mission.

During the **T-15 Mins** (15 Mins. Before the launch), if there occurs any criticality with the rocket, these two could take the call for **whether to go for the launch or make it delayed.**

It might be the dream of many aspirants to lead a mission from this control center & we were fortunate enough to spend nearly half an hour there!

### **Launchpads**

The bus dropped us next near the **Launchpad I**. As a rocket was in the development stage that day, we were allowed to observe it only from a certain distance.

This one is regarded as the **oldest** and the most reliable Launchpad of ISRO which had India’s successful **Mars Orbiter Mission (MOM)** launched back in Nov 2013 to its credit along with numerous successful missions.

Just standing at that place and observing the assembling process of the rockets was quite a fulfilling experience for me. I was overwhelmed with the sense of respect for those countless unsung scientists who pull their socks and work round the clock in service of mankind.

Followed by this, we arrived at Launchpad **II,** credited with the launch of India’s Moon Mission **Chandrayan II** in 2019 along with the other ones. Although I had seen the videos of several launches from here on the television screens before the visit, I was blown away by the majestic structure installed by the ISRO.

The nearly **80-meter tall** building known as the **umbilical tower** is used for **fuelling & launching the rocket** after getting assembled at a building present exactly 1 KM away from that place.

The structure is much larger and more dynamic than it appears in the photographs. One must visit here once to perceive this fact!

As there was no space mission under progress on the day of our visit, we had the scope to move to an extremely close area of the launchpad which certainly gets **unmanned on the launching days.**

### **It's the time to wrap up!**

The rest of the journey included the observation of the powerful **antennas and radars** installed to capture satellite data, checking a model of the rocket and spending a few minutes in the space museum singing the glittering past of this premier space agency.

The trip concluded with a meal in the canteen and a few clicks at the main gate of SDSC-SHAR where **photography** is permitted.

Meanwhile, I ensured every detail of this tour was entered into my **diary** for the reference in future, along with the **autographs of every single person** on this trip to freeze these moments for the years to come.

Probably, any sum couldn’t replace the experience that ISRO had given us in that one single day! If life permits, I’d not hesitate ever to be in that place again!

We were once at that place, where lies the path to break through the limitations of the sky and get into space!

***The memories of this still give me goosebumps!***
