China Launches Communication Technology Test Satellite 26A

China successfully launched the Communication Technology Test Satellite 26A on Tuesday, June 23, 2026, from the Wenchang Spacecraft Launch Site in Hainan Province. The satellite was carried into orbit by a Long March 7A carrier rocket and has successfully entered its designated orbit, with the China National Space Administration (CNSA) declaring the mission a complete success, according to Xinhua News.

Mission Overview

The launch took place from China’s only coastal spaceport, the Wenchang Spacecraft Launch Site on the northeastern coast of Hainan Island. The Long March 7A rocket lifted off precisely on schedule, delivering the satellite into its intended orbit approximately ten minutes after launch. Official announcements from Chinese state media confirmed the mission’s success later that morning.

China Central Television (CCTV) reported that this mission marked the 653rd flight of the Long March series of carrier rockets, underscoring the remarkable scale and maturity of China’s space launch program, which has conducted over 650 orbital launches since its first successful launch in 1970.

Satellite Purpose and Capabilities

The Communication Technology Test Satellite 26A (also designated TJS-26A) is primarily designed for satellite communications, broadcasting, television, and data transmission services, and will conduct related technology test verification experiments in orbit. As People’s Daily reported, the satellite serves as an orbital testbed for new communication technologies before they are deployed on operational systems.

The satellite belongs to China’s long-running Communication Technology Test Satellite (TJS) series, which began launching as early as 2015. These satellites are used for multi-band, high-rate satellite communication technology verification, forming a systematic technology development program. The “A” designation in “26A” suggests this may be part of a multi-satellite batch or a variant within the numbering system, potentially indicating a future TJS-26B launch.

The Long March 7A Rocket

The Long March 7A is a medium-to-high-orbit liquid-fueled carrier rocket developed by the China Academy of Launch Vehicle Technology (CALT) under the China Aerospace Science and Technology Corporation (CASC). It is a variant of the Long March 7, designed to fill China’s gap in geosynchronous transfer orbit (GTO) payload capacity of 5.5 to 7 tons.

The rocket stands approximately 60 meters tall with a liftoff mass of about 573 tons. It uses non-toxic, non-polluting propellants — liquid oxygen and kerosene for its boosters and first and second stages, combined with a liquid hydrogen and liquid oxygen third stage inherited from the Long March 3A series. After an initial maiden flight failure in March 2020, the Long March 7A returned to flight successfully in March 2021 and has since conducted multiple successful missions from Wenchang.

Launch Cadence and Space Program Context

This launch follows closely on the heels of the previous TJS mission — the Long March 7A successfully launched the Communication Technology Test Satellite 24 from Wenchang on May 27, 2026, which was the 645th Long March flight. The gap of only 27 days between these two launches demonstrates China’s increasing launch capacity and the maturation of the Long March 7A platform.

As Guancha noted, 2026 is shaping up to be a high-density launch year for China’s space program. Key planned missions include the first flight of the new-generation reusable crew spacecraft “Mengzhou” using the Long March 10A from Wenchang, continued space station application phase operations, and the ongoing deployment of China’s satellite internet constellation, known as “Starnet” or the GW constellation.

Analysis and Implications

The successful launch of TJS-26A continues China’s systematic approach to space communication technology development. Each satellite in the TJS series tests new capabilities that ultimately feed into operational systems, supporting China’s ambitions in satellite communications with both civilian applications — such as broadband and broadcasting — and dual-use capabilities.

China’s space program remains a key component of its national strategy for technological self-reliance and its goal of “building a space power.” The technologies verified on TJS satellites may eventually be commercialized for China’s satellite internet constellation, while the country’s growing space capabilities continue to reshape the global space landscape with implications for satellite communications markets and space governance.

What’s Next

With the 653rd Long March flight now in the books, attention turns to China’s ambitious 2026 launch manifest. The upcoming Mengzhou crew spacecraft test flight, further TJS series launches, and continued space station operations are all expected in the months ahead. The rapid launch cadence — approximately eight launches in less than a month — suggests no slowdown in China’s space ambitions.

Open questions remain about the specific new communication technologies being tested on TJS-26A, the satellite’s precise orbital parameters, and whether a companion TJS-26B satellite will follow. What is clear is that China’s space program continues to advance at a remarkable pace, with each successful mission building on the last.
