Can NASA compete with the more cost-efficient SpaceX?Robert Block
The Artemis mission has also faced criticism from people who believe Elon Musk's SpaceX offers a more cost effective and efficient way to travel to space. 阿尔特弥斯任务也面临着一些人的批评,他们认为埃隆·马斯克的美国太空探索技术公司提供了一种更经济、更高效的太空旅行方式。 NASA has big plans ...

Dr. Dodson also said, “An NTR achieves high thrust similar to in-space chemical propulsion but is two to three times more efficient. With a successful demonstration, we could significantly advance humanity’s means for going faster and farther in space and pave the way for the future deployme...
NASA’s Ingenuity helicopter has just flown faster than ever over the surface of Mars. The drone-like flying machine reached a speed of 10 meters per second (22.4 mph) during its 62nd flight on the planet, breaking its previous speed record of 8m/s (17.9 mph) set two flights previously...

That’s the aim of the Deep Space Optical Communications test, which has hitched a ride on the Psyche mission headed to the solar system’s main asteroid belt to test whether it’s possible to use lasers for more efficient communications. The experimentsent back its first test data last year...
Challenges include precisely aligning the transmitters and receivers and making the components small, light and power efficient enough for use in space. ILLUMA-T and LCRD belong to NASA Space Communications and Navigation (SCaN) program. Using laser communications greatly increases the efficiency of dat...
