1 .SpaDeX:
(General Studies-III (250 marks)Technology, Economic Development, Biodiversity, Environment, Security, and Disaster Management)
is a cost-effective technology demonstrator mission for the demonstration of in-space docking using two small spacecraft launched by PSLV. This technology is essential for India’s space ambitions such as Indian on Moon, sample return from the Moon, the building and operation of Bharatiya Antariksh Station (BAS), etc.

In-space docking technology is essential when multiple rocket launches are required to achieve common mission objectives. Through this mission, India is marching towards becoming the fourth country in the world to have space docking technology.
Objectives:
The primary objective of the SpaDeX mission is to develop and demonstrate the technology needed for rendezvous, docking, and undocking of two small spacecraft (SDX01, which is the Chaser, and SDX02, the Target, nominally) in a low-Earth circular orbit. Secondary objectives include:
Demonstration of the transfer of electric power between the docked spacecraft, which is essential for future applications such as in-space robotics,
Composite spacecraft control, and
Payload operations after undocking.
Mission Concept:
The SpaDeX mission consists of two small spacecraft (about 220 kg each) to be launched by PSLV-C60, independently and simultaneously, into a 470 km circular orbit at 55° inclination, with a local time cycle of about 66 days. The demonstrated precision of the PSLV vehicle will be utilized to give a small relative velocity between the Target and Chaser spacecraft at the time of separation from the launch vehicle.
This incremental velocity will allow the Target spacecraft to build a 10-20 km inter-satellite separation with respect to the Chaser within a day. At this point, the relative velocity between the Target will be compensated using the propulsion system of the Target spacecraft.
At the end of this drift arrest maneuver, the Target and Chaser will be in the same orbit with identical velocity but separated by about 20 km, known as Far Rendezvous. With a similar strategy of introducing and then compensating for a small relative velocity between the two spacecraft, the Chaser will approach the Target with progressively reduced inter-satellite distances of 5 km, 1.5 km, 500 m, 225 m, 15 m, and 3 m, ultimately leading to the docking of the two spacecraft.
After successful docking and rigidization, electrical power transfer between the two satellites will be demonstrated before undocking and separation of the two satellites to start the operation of their respective payloads for the expected mission life of up to two years.
The indigenous technologies developed for enabling this docking mission are as follows:
Docking mechanism,
A suite of four rendezvous and docking sensors,
Power transfer technology,
Indigenous novel autonomous rendezvous and docking strategy,
Inter-satellite communication link (ISL) for autonomous communication between spacecraft, incorporated with inbuilt intelligence to know the states of the other spacecraft,
GNSS-based Novel Relative Orbit Determination and Propagation (RODP) processor to determine the relative position and velocity of the other spacecraft,
Simulation test beds for both hardware and software design validation and testing.
In addition, SpaDeX, because of its small size and mass, is even more challenging due to the finer precision required for the rendezvous and docking maneuvers compared to docking two large spacecraft. This mission will be a forerunner for autonomous docking needed for future lunar missions like Chandrayaan-4 without the support of GNSS from Earth.
Docking Mechanism:
The docking mechanism is a low-impact docking system (approach velocity is in the order of 10 mm/s), androgynous (docking systems are identical for both spacecraft, Chaser & Target), and is a peripheral docking system (concept similar to the International Docking System Standard used by other agencies for human missions).
The mechanism is smaller (450 mm) with one degree of freedom for extension and uses two motors compared to the IDSS (800 mm) on a hexapod with 24 motors. Multiple test beds were established to test the hardware and software simulation of the docking kinematics to verify and finalise the docking
approach parameters.
2 .PM Modi extends greetings on Uttar Pradesh’s 76th foundation day:
(GS Paper II: Governance, Constitution, Polity, Social Justice and International Relations)
Uttar Pradesh celebrated its 76th Foundation Day on January 24, 2025, commemorating the renaming of the United Provinces to Uttar Pradesh on that date in 1950.
The celebrations, held at Awadh Shilp Gram in Lucknow, spanned three days, showcasing the state's rich cultural heritage and highlighting its ongoing development. Six individuals were honored with the "Uttar Pradesh Gaurav Samman" for their exceptional contributions in fields like music, agriculture, and education.
Chief Minister Yogi Adityanath emphasized the state's rich history while outlining a vision for a progressive and self-reliant Uttar Pradesh. The Foundation Day served as a platform to reflect on the state's journey, celebrate its achievements, and unite in the mission of fostering a prosperous future.
