Congratulations!
Global first!
Just now, China's laser pierced the sunlight!
When solar flares obscured the starry sky, Chinese scientists completed an "universe needle"-level operation at noon. On the 29th, the "Tian Du No.1" satellite tore through the sunlight barrier and achieved global-first white-light lunar space laser ranging! This "light-year skill," which once appeared in sci-fi movies, marks a breakthrough in China's deep-space exploration technology that surpasses physical limits. The difficulty of this technology is akin to hitting a coin on the moon with a laser pointer at an Olympic shooting range. The satellite laser ranging needs to capture micron-level signals from 380,000 kilometers away, while the daytime solar background light intensity is one billion times stronger than starlight. China's scientific research team's innovative "photon sieve" technology is like equipping detectors with quantum-grade "sunglasses," accurately capturing satellite echoes from strong light noise, extending observation time from 7 days of the lunar night to all-day observation. As the "space comrade" of the "Magpie Bridge No.2," the "Tian Du No.1" has already built the first all-weather laser channel between Earth and Moon. This breakthrough not only paves the way for "centimeter-level positioning" expressways for international lunar research stations but also enables China to master the "optical clock" of deep-space exploration. As aerospace experts said, "While others are still chasing starlight, we have learned to weave a Milky Way coordinate system in the fiery sun." This laser ballet in broad daylight is dancing out the precision of China among the stars and seas.
