A Chinese communication and navigation technology test satellite, known as the Tiandu-1, has recently conducted a laser ranging technology test in the Earth-Moon space under strong daylight interference conditions, marking a world first, according to the satellite's developer, China’s Deep Space Exploration Lab (DSEL), on Tuesday.
This achievement represents a major technological breakthrough for China in the field of precise measurements in deep space orbits.
Laser ranging on satellites in the Earth-Moon space is akin to targeting a single hair from 10,000 kilometers away while performing precise tracking and signal capture. In the past, such tests could only be conducted at night when light interference was minimal.
The successful daylight laser ranging test has effectively expanded the observation window, providing crucial support for major deep space exploration missions, such as the International Lunar Research Station.
The Tiandu-1 and Tiandu-2 satellites were launched into space alongside the Queqiao-2 relay satellite on March 20, 2024. They entered their target circumlunar orbits on March 29 and separated on April 3. The Tiandu-1 has already completed multiple new technology tests in orbit.

China launched the second event of its 2026 "Big Market for All: Export to China" campaign in Hangzhou City of east China's Zhejiang on Sunday, as part of the country's broader push to expand imports and tap the purchasing power of its vast consumer market.
The three-day event, co-hosted by China's Ministry of Commerce and the People's Government of Zhejiang Province, is bringing together global brands, importers and consumers under one roof.
Minister of Commerce Wang Wentao attended the launch ceremony of the event and delivered an address.
More than 1,000 imported products are on display, from food and consumer goods to advanced industrial components.
The campaign aims to turn China's massive market into a gateway for global products, according to officials.
"The event highlights China's determination to independently expand unilateral and self-reliant opening-up. It is also China's active response to the needs of its global trading partners and our practical step to work together with them to grow the pie of international trade," said Xiao Lu, deputy director of the Department of Foreign Trade at the Ministry of Commerce.
Nearly 100 import-focused companies are taking part, showcasing products and exploring opportunities in China's fast-growing consumer market.
"We have selected popular product choices favored by Chinese tourists who have visited Egypt," said Cao Kezhen, chief representative for China at the CHIMENA (China-India-Middle East-North Africa) Business Council.
Starting from May 1, 2026, China will fully implement zero-tariff treatment for 53 African countries that have established diplomatic relations with China, so many Egyptian businesses are eager to explore the Chinese market, Cao said.
New technologies are also helping bring overseas products closer to Chinese consumers.
"In recent years, China has introduced a range of policies to encourage imports. These measures allow Chinese consumers to buy quality products from around the world at competitive prices through cross-border e-commerce. Going forward, we plan to shift more focus onto the development of a digital supply chain from the traditional supply chain, customs declaration and inspection, logistics, warehousing and distribution," said Shan Li, chairman of High Store Tech, a supply chain service provider for global brands.
Sunday's event followed the inaugural gathering, which took place under the same theme in the national capital Beijing in February.
