So now, it is important that the United States has an independent capability of being able to launch people to space. Demo-2 will be the first time that the Dragon spacecraft takes astronauts into space, and if the demonstration mission goes to plan, SpaceX is contracted to supply six more flights to the ISS.
The return of launches to U. Boeing is slightly behind SpaceX though, with the company hoping to conduct a manned test flight of the Starliner in Read more.

Astronomers will also use Webb to look at how galaxies form and evolve, to study the birth of stars, and to learn more about the atmospheres of planets that may be hospitable for life outside our solar system.
Webb will be the largest space telescope ever launched, with a primary mirror made of 18 gold-coated beryllium segments stretching to a diameter of A decade ago, the Obama administration and Congress outlined three priorities for NASA in the s: Debut new commercial crew and cargo transportation to help utilize the International Space Station, develop the SLS and Orion spacecraft, and complete construction of Webb.
At the time, NASA aimed to launch the first commercial crew flight to the space station in Both programs faced delays, but the commercial crew contracts were set up as fixed price agreements, meaning the contractor was responsible for paying for cost overruns. As before, NASA will adapt solutions to these and other challenges into technologies that will improve life at home.
NASA is developing more advanced printers that can add metals and other materials like regolith into the mix. Being able to make parts in space will come in handy during emergencies. Communicating from Earth to any spacecraft is a complex challenge, largely due to the extreme distances involved. When data are transmitted and received across thousands, millions, and even billions of miles, the delay and potential for disruption or data loss is significant.
Advanced communication technologies are essential to enhance deep space exploration for both robotic and human missions. DTN will enable a Solar System Internet with automated data delivery between users no matter how distant and intermittent their connections may be. The modems encode data into laser light to be transmitted to the ground from a satellite orbiting at the same speed Earth is turning. Nearly a half-century ago, Apollo 11 astronaut Neil Armstrong walked on the Moon.
NASA is now preparing for an ambitious new era of sustainable human spaceflight and discovery. The agency is building the Space Launch System rocket and the Orion spacecraft for human deep space exploration. With the help of commercial and international partners, NASA will develop new opportunities in lunar orbit, including a platform to aid surface exploration and serve as a gateway to Mars.
The space station will also facilitate the growth of additional privately owned spaceships for continued research and transportation in low-Earth orbit.
