On-orbit Satellite
Refueling:
ISRO is planning to demonstrate
on-orbit satellite refueling by 2025.
This would be a significant
milestone for the space industry,
as it would allow satellites to be
refueled and extended their
lifespans. ISRO is currently
developing a robotic refueling
system that would be attached to
a spacecraft and used to refuel
other satellites in orbit. The system
would use a robotic arm to
grapple the refueling target
satellite and then connect a fuel
line. The fuel would then be
transferred from the refueling
spacecraft to the target satellite.
Quantum communications
ISRO's 2025 plan involves
developing quantum
communication technology for
secure long-distance space
communication. This includes
launching a quantum
communication satellite, setting
up ground stations, and creating
space-specific QKD protocols.
Quantum communication
enhances security and enables
secure data transmission over
long distances in space.
