ISRO Launches SpaDeX Mission for Space Docking

News:
The Indian Space Research Organisation (ISRO) successfully launched the Space Docking Experiment (SpaDeX) mission to demonstrate spacecraft rendezvous, docking, and undocking technologies.

Mission Details:

• Launch Vehicle: PSLV-C60.
• Satellites: Two small satellites, SDX01 (Chaser) and SDX02 (Target).
• Payloads: 24 additional experimental payloads.
• Orbit: Satellites were placed in a 475-km circular orbit.

Objectives:

• The mission aims to develop space docking technology essential for future projects such as:
• Manned lunar missions.
• Lunar sample return missions.
• Indian Space Station operations.

Key Milestones:

• The two satellites were launched and separated successfully.
• Over the next few days, they will drift apart by about 20 km before initiating the docking process, expected between January 7 and 10.

Importance:
Only a few spacefaring nations have mastered space docking, and this mission places India among this elite group, further advancing its space capabilities.

Space docking is a sophisticated technology mastered by only a few spacefaring nations. These countries possess advanced capabilities for orbital rendezvous, docking, and undocking essential for space station operations, crewed missions, and interplanetary exploration. Here are the key nations:

1. United States (NASA)

• Key Achievements:
• NASA's Apollo missions (lunar orbit docking).
• The Space Shuttle program (docking with the International Space Station - ISS).
• Crew Dragon (SpaceX) routinely docks with the ISS.
• Development of the Artemis program for lunar docking.

2. Russia (Roscosmos)

• Key Achievements:
• Mastered docking during the Soviet era with missions like Soyuz and the Mir Space Station.
• Continues to play a major role in ISS docking operations using Progress and Soyuz spacecraft.
• The Luna program (lunar docking missions).

3. China (CNSA)

• Key Achievements:
• China demonstrated autonomous docking with the Tiangong space station.
• The Shenzhou spacecraft docked successfully with Tiangong-1, 2, and 3.
• China is expanding space station operations with the Tiangong Space Station.

4. Japan (JAXA)

• Key Achievements:
• JAXA has docked the HTV (H-II Transfer Vehicle) with the ISS.
• Participates in international docking operations, contributing cargo to the ISS.

5. European Union (ESA)

• Key Achievements:
• ESA developed the Automated Transfer Vehicle (ATV), which docked with the ISS multiple times.
• ESA collaborates with NASA for Artemis and lunar gateway projects involving docking.

6. India (ISRO) (Emerging)

• Key Achievements:
• ISRO’s SpaDeX mission (2024) aims to demonstrate autonomous docking for the first time.
• India plans to incorporate docking in the Gaganyaan crewed mission and future lunar missions.
