This event marked yet another significant milestone in India's space research program.
The PSLV-C60/SPADEX mission was launched on December 30, 2024. Following the launch, the first successful docking occurred on January 16, 2025, at 6:20 a.m. The satellites were later undocked on March 13 at 9:20 a.m..
Isro has also announced that further experimental procedures are scheduled to take place over the next two weeks. He further wrote," As informed earlier, the PSLV-C60 / SPADEX mission was successfully launched on 30 December 2024. Thereafter, the satellites were successfully docked for the first time on 16 January 2025 at 06:20 AM and successfully undocked on 13 March 2025 at 09:20 AM. Further experiments are planned in the next two weeks."
On March 13, Isro announced the successful completion of its SpaDeX mission's space de-docking. The undocking process involved a precise sequence of events, culminating in the separation of the SDX-01 (Chaser) and SDX-02 (Target) satellites, which were launched on December 30, 2024, using the Polar Satellite Launch Vehicle (PSLV)-C60 from the Satish Dhawan Space Centre in Sriharikota.
It included the successful extension of SDX-2, the planned release of Capture Lever 3, and the disengagement of the Capture Lever in SDX-2. After these manoeuvres, the decapture command was issued in both SDX-1 and SDX-2, leading to the successful separation of the satellites.
Isro successfully completed the docking of the two SPADEX satellites (SDX-01 and SDX-02) in the early hours of January 16 this year, marking India's entry towards becoming the fourth country, alongside China, Russia, and the United States, in the world to have space docking technology.
According to the space organisation, the groundbreaking mission aims to showcase India's technological prowess in spacecraft rendezvous, docking, and undocking--a critical capability for future advancements, such as satellite servicing, space station operations, and interplanetary exploration.
It is a cost-effective technology demonstrator mission designed to demonstrate in-space docking using two small spacecraft launched by the PSLV.
This technology is essential for India's space ambitions, including sending an Indian to the Moon, returning samples from the Moon, and building and operating the Bharatiya Antariksh Station (BAS). In-space docking technology is essential when multiple rocket launches are required to achieve common mission objectives.
The SpaDeX spacecraft was designed and realised by the UR Rao Satellite Centre (URSC) with the support of other Isro centres (VSSC, LPSC, SAC, IISU, and LEOS).

New Delhi: The first uncrewed mission of the Gaganyaan human spaceflight mission, G1, is ready to launch with the half-humanoid robot -- Vyommitra -- and the launch is expected in December, said V. Narayanan, Chairman of the Indian Space Research Organisation (ISRO) on Thursday. Speaking at a press briefing in the national capital, he also lauded IAF Group Captain Shubhanshu Shukla for his successful mission to the International Space Station -- the first ever by an Indian. Shukla is one of the astronauts selected for the crewed Gaganyaan mission. "The first uncrewed mission, G1, is going to be lifted off by this year's end, maybe close to December. And in that, the Vyommitra, the half-humanoid, is going to fly," Narayanan said, while thanking Prime Minister Narendra Modi for announcing the Gaganyaan programme on August 15, 2018. Lauding the space organisation's efforts, Narayanan said that ISRO made a lot of accomplishments in the last four months. "The entire ISRO programme is purely a teamwork of 20,000 employees, 450 industrial partners and 300 academia partners. Today, along with us, we have got the Gaganyatris joining in hand in hand for our programmes". Mentioning various programmes of ISRO, he stated: "There is telemedicine, tele-education, television broadcasting, and real-time connecting of something around 8,600 trains, 21,000 shipping vessels are connected". Further, the noted rocket scientist said: "ISRO is doing an outstanding job in the area of disaster warning". "A total of 13 out of 17 UN Sustainable Development Goals are being supported by ISRO," he said, while also listing other space achievements like the Aditya L1 Sun mission and the NISAR satellite mission. "We have made a major breakthrough in Cryogenic engine technology. The tests are going very well, and a lot of indigenisation activities are progressing well. "Coming to the Aditya L1, this year we have released 13 terabit data," he said, calling the images of Sun's orbit taken by the satellite, "fantastic achievement". He added that the recently launched NASA ISRO Synthetic Aperture Radar Satellite (NISAR) satellite "is healthy and all systems are working well". "NISAR, launched on July 30, is jointly realised by NASA, JPL, and ISRO. It is the costliest satellite ever realised in the world, and it was lifted off by the Indian launcher GSLV and placed perfectly in orbit. Today, the satellite's health is totally perfect, and the antenna, unfurled (after 17 days), is operational. We will share the first pictures in a couple of days. "In two to three months, we are also going to launch a 6,500 kg communication satellite of the US, on our launch vehicle. To date, 433 satellites of 34 countries have been launched from India," the ISRO chief said.
