India Joins Elite Club of Spacefaring Nations With Latest Orbital Test

ISRO—India’s space agency—successfully completed the docking of two spacecraft in orbit, a major accomplishment that makes the agency just the fourth to manage the feat.

The dramatic docking between two satellites occurred late yesterday about 295 miles (475 kilometers) above Earth. The accomplishment is significant; besides the fact that India is now just the fourth country to dock spacecraft in orbit, it is a milestone in the country’s ambitious space program.

According to SpaceNews, the two spacecraft—launched on December 30—were supposed to dock on January 7, but drift in the satellites’ position delayed the maneuver. ISRO announced the docking’s success on X yesterday, and noted that undocking and power transfer checks on the spacecraft will occur in the coming days.

Narendra Modi, India’s prime minister, stated on X that the accomplishment “is a significant stepping stone for India’s ambitious space missions in the years to come.”

Today, ISRO announced that the government approved a third launch pad at the agency’s Satish Dhawan Space Center. According to the agency release, the additional launch pad “boost the Indian Space ecosystem by enabling higher launch frequencies and the national capacity to undertake human spaceflight & space exploration missions.” The agency plans to finish construction of the launchpad within four years.

The docking test success is the latest milestone for ISRO, which is rapidly ramping up its efforts across spaceflight.

In 2019, India deliberately knocked out one of its own satellites in a show of force that planted the country’s flag as a power in space. India became only the fourth country to display anti-satellite (ASAT) capability, after Russia, China, and the United States. India also has ambitions beyond low Earth orbit. In 2023, the country’s Chandrayaan-3 mission landed on the Moon and immediately made observations of its south pole. That same year, India’s Aditya-L1 mission successfully launched and began observing space weather and its effects on our planet. In 2023, the Gaganyaan demonstrator laid the groundwork for what should be ISRO’s first crewed space mission.

Congrats #ISRO. Finally made it. SPADEX has accomplished the unbelievable… docking complete… and it is all indigenous “Bharatiya Docking System”. This paves the way for smooth conduct of ambitious future missions including the Bharatiya Antriksha Station, Chandrayaan 4 &…

Jitendra Singh, India’s Minister of State for Science and Technology, heralded the recent docking in a social media post, noting that it eases the path forward for several ISRO missions. An uncrewed Gaganyaan test flight is planned for later this year, which if successful will put the agency a big step closer to sending people into space.

At the risk of flying to close to a cliché, it was a relatively straightforward maneuver for the ISRO spacecraft, but a big step—and a statement of intent—for the country’s space program.
