The issue focused on ongoing discussions between NASA and SpaceX over technologies like unmanned spacecraft that could potentially fly astronauts into deep space. The talks included engineering proposals for exploring Mars as well as approaches to exploiting emerging technologies such as robotics.

Several experts suggested NASA might instead explore sending humans back to Earth if technology improves its capabilities in science. NASA scientists believe NASA would eventually reach an agreement with NASA about NASA's capability to send astronauts back to Earth by 2025.Hi guys, This week we're gonna talk about physics theory
