Can NASA compete with the more cost-efficient SpaceX?Robert Block
For more than 40 years, NASA astronauts have performed spacewalks outside the space station for maintenance and upgrades while wearing the Extravehicular Mobility Unit (EMU) spacesuit design that debuted during the Space Shuttle Program in the 1980s. While the spacesuit has far exceeded its planned...
— SpaceX (@SpaceX)March 12, 2025 During its two-year mission, theSPHEREx(Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) Observatory will gather data on more than 450 million galaxies and more than 100 million stars. The collected data will help...

"It’s getting increasingly real," Henry Stone, Psyche's project manager at NASA's Jet Propulsion Laboratory (JPL) in Southern California, said in astatement on Wednesday. "We are counting the days. The team is more than ready to send this spacecraft off on its journey, and it's very...

stainless steel rocket and spaceship is faster, more efficient, and less disruptive than trying to convince NASA to get its foot in the door, SpaceX might have to forge its own path. If SpaceX can raise enough funding to develop its next-generation rocket independently, what comes next is ...
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 ...
make its four-to-seven-month trip to the Moon (depending on the launch date) as efficient as possible, the mission’s design and navigation team has planned a trajectory that will use the gravity of the Sun, Earth, and Moon to guide the spacecraft — a technique called low-energy ...
This was supposed to be a much more efficient and streamlined option than relying on commercial options for deep space missions. At the time, private US rockets — like ULA’s Atlas V and Delta IV, or SpaceX’s fledgling Falcon 9 rocket — would have needed to launch multiple rockets to...
