Have you ever wanted to work with ISRO scientists on real rocket science and satellite data? The Bharatiya Antariksh Hackathon 2026 is your ticket to doing exactly that. ISRO just launched the third edition of this massive space-tech hackathon, and registrations are officially open. You don't need to be a PhD rocket scientist to apply. Whether you are building an AI model for weather prediction or writing code to find lunar ice, this guide breaks down how to get in.
Things are moving fast.
Honestly, they want student minds to solve 15 problems. In my experience, getting into space tech is usually a massive pain. Look, we cover a lot of these space policy shifts in our latest tech news section. But today, let's focus on how you get in.
The timeline you need to remember
Don't wait until the last minute. The registration window is narrow, and you'll need time to form a team and write a solid proposal. Here's the schedule you must follow:
- June 15 and June 16, 2026: Online sessions where ISRO scientists explain each problem statement in detail.
- July 1, 2026: The absolute deadline for submitting your team registration and proposal.
- July 20, 2026: Announcement of selected teams that make it to the finals.
- August 6 and August 7, 2026: The grand finale hackathon. Finalists will build their solutions during a 30-hour run.
If you ask me, you really should attend the explainer sessions on June 15 and 16. Missing them is a bad idea. They are your only chance to ask questions directly to the scientists who designed these challenges.

Who can apply? Eligibility criteria for the hackathon
ISRO's kept the rules pretty simple but strict. They want students. Corporate professionals can't get in. This is how they keep things fair for younger innovators.
Only students currently enrolled in undergraduate, postgraduate, or doctoral programs at recognized Indian institutions can register. Working professionals can't participate.
Here's what you need to meet before you hit that sign-up button:
- You must form a team of 3 to 4 members. Solo participation is not allowed.
- All team members must be from the same college or university, or you can mix and match from different Indian institutions if you prefer.
- Your team must select one leader who will handle all submissions and communications.
- You must have a faculty mentor from your college, though this is usually optional for PhD scholars.
I think this student-only rule is a great decision. Too often, national hackathons get dominated by experienced software engineers who build polished products in their free time (which is incredibly annoying, if you ask me). By limiting this to active students, ISRO makes sure raw academic research gets a real chance.
The role of your faculty mentor
Don't just pick any professor as your mentor. Get someone who knows data science. They won't write the code, obviously, but they'll help you refine the technical proposal that determines whether you make the cut. Plus, they are the official contact point between your college and ISRO. That saves a lot of administrative headaches.
Forming inter-college teams
One cool thing is the flexibility in team building. You don't have to stay in your own department or college. If you're a computer science student who knows Python, but you need someone who understands orbital mechanics, you can partner with an aerospace student from another university. This is exactly how real space missions are built.
The 15 ISRO space-tech challenges you can solve
ISRO's divided the 15 challenges into multiple technical areas. In my experience, these are not dummy projects. They're real problems that scientists at space centers face every single day. Let's break down the best ones.
Predicting solar flares with Aditya-L1 data
India's first solar observatory, Aditya-L1, is constantly monitoring the sun. It's collecting massive amounts of solar radiation data. One challenge asks you to use this data to predict solar flares (which makes sense, actually, because flares can wreck satellites and disrupt networks on Earth). An AI model that predicts them before they hit can save millions of dollars in space assets.
Finding water on the moon
Finding ice on the lunar south pole is a big deal for future space missions. The Chandrayaan-2 orbiter is still sending back high-resolution radar data. Your job is to analyze this data. You'll need to write algorithms that tell the difference between dry lunar soil and ice hidden just below the surface. This is heavy math, but it's incredibly important for future bases.
Building a digital twin of India's climate
This one is the most ambitious challenge. They want you to build a digital twin of our climate. Think of it as a massive simulation that uses satellite weather data to model temperature changes and monsoons. It helps cities plan for extreme weather. It's a massive task that requires handling petabytes of climate data.
Monitoring air quality and forecasting radiation
Air pollution is a major concern across Indian cities. Another challenge focuses on using satellite remote sensing to track particulate matter and predict air quality trends. Alongside this, there's a space radiation forecasting problem. High-energy cosmic rays and solar particles pose a constant threat to electronic systems in orbit. Teams must build predictive models to warn satellite operators about incoming radiation spikes. This is super important for space safety.
Other challenges cover rover mobility and crop health monitoring. Go check out the full list of fifteen problems on the registration portal.
How to register: Step-by-step hackathon registration
Registrations are managed through the Hack2Skill platform. Honestly, the numbers here are a bit fuzzy, but we try to track online safety in our scam warning repository to keep you safe. In my experience, scammers love targeting these events, so watch out for sketchy links. Follow these steps to register safely:
- Go to the official portal at https://hack2skill.com/event/bah2026/ to start.
- Create a team profile and add the details of all your members. Ensure you have their student ID cards ready for verification.
- Select your preferred challenge from the list of fifteen.
- Submit a detailed proposal document. This document must explain your approach, the tools you plan to use, and why your team is qualified.
- Wait for the evaluation. ISRO scientists will review every proposal and select the best ones for the final round.
Signing up is totally free. You don't need to pay a single rupee to submit your proposal. So if a website asks for money, close it immediately.
Why this space hackathon is different
Most college hackathons end with a certificate and a small cash prize. This is different. Finalists travel to an ISRO center (which is a massive deal, honestly). If you ask me, getting to work alongside ISRO scientists who mentor you is the real prize.
Think about it. Having a recommendation letter or mentorship record from an ISRO scientist on your resume is worth far more than any cash prize. It's going to open doors to research positions or space startups. India's space sector is growing rapidly, and private companies want people who know how to handle satellite data. This is the easiest way to prove you have those skills.
A launchpad for private space careers
India's private space sector has exploded over the last few years, with startups building their own launch vehicles and satellites. These companies need engineers who have worked with real-world geospatial datasets and space physics. Participating here and analyzing actual ISRO data puts your resume right at the top of the pile.
So, grab some friends and start working on your proposal. The July 1 deadline is coming up fast.
