一 |     Russia's Luna-25 probe likely left a 33-foot-wide crater on the surface of the moon last month when it lost control and crashed down, NASA said Thursday, revealing images that show the suspected impact site.Russia's first moon mission in 47 years ended in failure on August 19 when the Luna-25 probe smashed into the moon after a thruster firing went awry, cutting off communications and putting the spacecraft on the wrong orbital path, according to Roscosmos, the Russian space agency.NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft captured images last week of what the U.S. space agency described as a "new crater" after Roscosmos published an estimate of where the probe had struck.

During the descent to the surface on August 19, the Russian spacecraft Luna-25 experienced an anomaly that caused it to smash into the moon's surface. The faiint arrow in this NASA image shows where the agency believes the probe made impact.                    NASA's Goddard Space Flight Center/Arizona State University             
"Since this new crater is close to the Luna-25 estimated impact point," NASA wrote in a statement, "the LRO team concludes it is likely to be from that mission, rather than a natural impactor."      Moscow has set up a commission to investigate exactly why Luna-25 crashed.The failure was a major disappointment for the Russian space program, which was attempting to up its game amid renewed interest in the moon's southern polar region, where ice deposits may exist in permanently shadowed craters. Ice could offer future space missions a way to produce breathable air, water and even hydrogen rocket fuel.                 The Russians have had little success with independent space exploration since the Luna-24 robot landed on the moon in 1976. It scooped up about six ounces of lunar soil and returned it to Earth in Russia's third successful robotic lunar sample return mission.Twelve NASA astronauts walked on the moon a half century ago in the agency's Apollo program, but no Russian cosmonauts ever made the trip. Russia's only previous post-Soviet deep space robotic missions, both targeting Mars, ended in failure.

Luna-25 was an attempt to pick up the torch and put Russia back into a new space race of sorts, as the U.S., China, India, Japan and the private sector all plan multiple moon missions that could lay the foundations for lunar bases and eventual flights to Mars.India's Chandrayaan-3 Vikram lunar lander made a historic touch-down near the moon's south pole just several days after the Russian probe crashed. It delivered a lunar rover that has already sent back data from soil samples.                      William Harwood contributed to this report.                                  。     8 月 26 日消息,联想 (Lenovo) 昨日宣布在 LOQ 和 Legion 两条游戏电竞产品线推出系列新品,而这其中就包括没有配备独立显卡的 LOQ Essential 15IPH11 入门级游戏笔记本电脑。▲ LOQ Essential 15IPH11LOQ Essential 15IPH11 搭载英特尔酷睿 Ultra X7 处理器 358H,配备至高 16GB LPDDR5X-9600 内存,拥有至高 1TB M.2 2242 PCIe Gen4 SSD 存储,屏幕规格为 15.3" 1920×1200 165Hz 300nits 和 100% sRGB,内置 60Whr 电池,支持 Wi-Fi 6 & 蓝牙 5.3,续航达 21hr。▲ LOQ Essential 15IRH1联想还带来了一款外观类似的独显机型 LOQ Essential 15IRH1。其则采用英特尔酷睿 200 系列处理器和 NVIDIA GeForce RTX 3050 笔记本电脑 GPU,配备 DDR5-5200 SO-DIMM 内存。▲ LOQ Tower 17IRH11台式机方面,联想则推出 LOQ Tower 17IRH11。其采用 MoDT CPU + 桌面 GPU 的硬件组合,至高可选英特尔酷睿 7 处理器 230H 和 NVIDIA GeForce RTX 5060 Ti (8GB) 显卡,整机体积 17L。▲ Legion 27U-20此外,联想还推出 Legion 27U-20 和 Legion 27Q-20 两款 IPS LCD 显示器,前者支持 UHD 180Hz / FHD 360Hz 双模、后者则是 QHD 320Hz,均具有 1ms 灰阶 (GtG) 响应时间、95% DCI-P3 色域、VESA DisplayHDR 400 认证。▲ Legion 27Q-202026 科隆游戏展专题。
