India Achieves Milestone in Space Technology with SpaDeX Mission..
Bengaluru: India has achieved a major step in space technology. ISRO has successfully demonstrated in-space docking through the SpaDeX mission. The mission was launched on December 21, 2024, using the PSLV-C60 rocket.
This achievement makes India one of the few countries to master this technology. It is essential for missions like returning samples from the Moon, building space stations, and human spaceflights.
ISRO officials called this a "game-changer" for India’s space exploration. An ISRO spokesperson said that the SpaDeX mission shows India’s ability to dock two satellites in space. This ability is essential for large missions that need multiple rocket launches.
What is SpaDeX?
The SpaDeX mission involved two satellites. These satellites were named SDX01 (Chaser) and SDX02 (Target). Each satellite weighs about 220 kilograms. They were launched into space at an altitude of 470 kilometers.
After being launched, the two satellites moved closer to each other in stages. They eventually docked successfully. The mission also tested transferring power between the docked satellites. This power transfer is essential for future long-term space missions.
“This mission is a major leap in our space journey,” ISRO said. “It will help us tackle ambitious projects like Chandrayaan-4 and the Bharatiya Antariksh Station.”
How It Works
The docking process was carefully planned. The satellites were launched at a slight distance apart. Onboard systems helped the satellites move closer to each other.
They finally docked at a slow speed of just 10 millimeters per second. After docking, ISRO tested the transfer of power between the satellites. This test proved that the satellites could share energy.
Once the tests were completed, the satellites were separated. They will now carry out their individual tasks.
Future Applications
The two satellites will work in space for two years. They will carry out several important tasks. These include high-resolution imaging for natural resources and vegetation studies.
One satellite has a high-resolution camera. The other satellite has a multi-spectral imaging system and a radiation monitor.
A National Effort
The SpaDeX mission was developed by ISRO’s UR Rao Satellite Centre. Several other ISRO centers and private companies also contributed.
ISRO’s ground stations are now controlling the satellites in orbit. This ensures smooth operations.
“This success is a proud moment for India,” ISRO said. “It brings us closer to our dream of having a strong space program.”
SpaDeX is a big step for India. It opens the door for more ambitious projects in the global space race.
