SOLAR SYSTEM

Detailed explanation-1: -The future of space flight will be the same as it is today: scientific robotic exploration and limited commercial missions, such as communication satellites. Meanwhile, the future of space travel for humans will still be a fantasy. These are just a few reasons why.

Detailed explanation-2: -NASA engineers will develop new technologies to improve air transport at home and meet the challenges of advanced space exploration. Our scientists will work to increase an understanding of our planet and our place in the universe. We will continue to try to answer the question, “Are we alone?”

Detailed explanation-3: -That  18 billion light-year figure is the limit of the reachable Universe, set by the expansion of the Universe and the effects of dark energy.

Detailed explanation-4: -The main objective of Space Biology research is to build a better understanding of how spaceflight affects living systems in spacecraft such as the International Space Station (ISS), or in ground-based experiments that mimic aspects of spaceflight, and to prepare for future human exploration missions far from Earth.

Detailed explanation-5: -The launch of a spacecraft comprises a period of powered flight during which the vehicle rises above Earth’s atmosphere and accelerates at least to orbital velocity. Powered flight ends when the rocket’s last stage burns out, and the spacecraft separates and continues in freefall.

Detailed explanation-6: -Apollo 10 reaches the fastest speed ever traveled by a human: 39, 897 km/h (11.08 km/s or 24, 791 mph), or roughly 1/27, 000 of lightspeed. Neil Armstrong and Buzz Aldrin were first to land on the Moon, during Apollo 11.
