ISRO Faces Satellite Replacement Delays
India's space agency, ISRO, has had three satellite missions fail in the last year.
These satellites were important for the country's security.
It will take ISRO 2-3 years to build and launch new ones to replace them.
Many parts for these satellites are made in other countries, which can cause delays.
Meanwhile, a Spanish start-up called Orbital Paradigm had a small capsule called KID that survived a failed mission.
The KID capsule was built quickly and cheaply, and it worked even better than expected.
This shows that small teams can make important space technology without spending a lot of money.
The success of the KID capsule could help with future space missions and offer new solutions for replacing lost satellites.
ISRO lost three strategic satellites in the last 12 months due to mission failures, causing significant financial losses and lost opportunities for India.
Replacing the lost satellites will take 2-3 years due to complex assembly and testing processes, and ISRO's limited annual launches (6-8).
Orbital Paradigm's KID re-entry capsule survived the failed PSLV-C62 mission, delivering valuable in-flight data and validating key technologies for future spacecraft.
The KID capsule was built in just one year by fewer than 10 engineers on a budget of under €1 million, demonstrating that high-performance space hardware can be developed quickly and cost-effectively.
The success of the KID capsule could offer alternative solutions for future missions and potentially accelerate the development of new spaceflight technologies.
