China's Lijian-1 Y5 commercial carrier rocket, which was launched Monday, sent 15 satellites, including one for Oman, into their planned orbits, marking the country's first commercial launch of an international satellite.
The Lijian-1 carrier rocket is a medium-sized launch vehicle with solid-fuel rocket engines, designed for rapid deployment of small and medium satellites into low to medium Earth orbits.
It was developed by CAS Space, a commercial spaceflight company established by the Institute of Mechanics under the Chinese Academy of Sciences. This rocket series completed its maiden flight on July 7, 2022, and has now launched a total of 57 satellites in the course of five flight missions, exceeding five tons of payload delivery.
Among the 15 satellites atop was Oman's remote-sensing satellite, marking China's first commercial launch for an international customer and underscoring the rocket's rising reputation in the global market.
"The cost of Lijian-1 carrier rocket is designed to be around 10,000 U.S. dollars per kilogram of payload. It's highly competitive globally in terms of reliability, cost, and mission adaptability," said Shi Xiaoning, chief designer of the Lijian-1 carrier rocket by CAS Space.
Successfully handling the launch of a foreign satellite demonstrates the Lijian-1's advanced technical capabilities. The timeline from Oman's confirmation of participation to launch took less than six months, showcasing the swift adaptability and responsiveness of the Lijian-1 technical team as they fine-tuned various technical parameters on short notice.
"Though it may appear to be a simple foreign satellite launch, this mission represents a significant technological accomplishment and underscores China's expanding international cooperation in space. Achieving success amid numerous challenges is truly a remarkable feat," said Yang Yuguang, chairman of the International Astronautical Federation's Space Transportation Committee.
Moving forward, plans are in place to expand the Lijian-1's capabilities with sea-based launches and missions targeting special orbital paths, enhancing its flexibility to better meet satellite users' diverse needs.

The Iranian government is focusing on public concerns and maintaining stable supplies of essential goods amid recent protests, Iranian President Masoud Pezeshkian said in a televised interview on Sunday.
In the city of Karaj, northwest of the capital Tehran, daily life has largely continued as normal. A video filmed by a local resident on Sunday shows food stores open and grocery shelves fully stocked.
"This is the block near my home, and there are some food stores here. Daily life continues here. Last night we did not see many protests in Karaj. Right now the city is very safe. This is a grocery store close to my home. All the food is available; nothing is in shortage. Here are noodles and different types of beans. Here are dairy products, cheese, and yogurt. I also checked other grocery stores and didn't see any shortages. Everything is available," said local resident Ali Reza.
Iranian officials have described recent disturbances as acts orchestrated by the "enemy," including some carried out by well-trained and armed "terrorists." The incidents have caused casualties among security personnel and civilians, as well as property damage.
The Secretary of Iran's Supreme National Security Council Ali Larijani has directed authorities to severely punish the "terrorists."
Meanwhile, Iran's police chief Ahmad-Reza Radan said on Sunday that the police had raised alert levels and arrested several leaders of the troublemakers during the operations on Saturday.
President Pezeshkian noted in the interview that the normal demands of the Iranian people are reasonable and justified, but they must realize that triggering riots and carrying out terrorist acts are the enemy's attempts to undermine the country. He urged the public to remain vigilant.
Also on Sunday, Iranian Parliament Speaker Mohammad Baqer Qalibaf warned that Tehran would regard U.S. and Israeli bases and facilities in the Middle East as "legitimate targets" if Washington takes military action against Iran. His remarks followed media reports saying U.S. President Donald Trump is "seriously considering authorizing a strike" against Iran.
Iranian state media reported that at least 109 members of Iran's security forces have been killed in clashes since the protests began 14 days ago. Meanwhile, human rights groups based outside the country said the number of protesters killed has exceeded 200, though the figure could not be independently verified.
The protests initially erupted over a sharp depreciation of the rial and sweeping subsidy reforms. Iranian authorities have blamed the unrest on foreign-linked agents and sanctions imposed by the United States.
