From 'cavewalking' to spacewalking

It might not be obvious, but there are many similarities between working deep underground and in outer space.

All-female spacewalk duo set sights on Moon

What's even better than venturing out into the vacuum of space? Landing on the Moon, according to US astronauts Christina Koch and Jessica Meir, the first all-female duo to conduct a spacewalk.

NASA and SpaceX hope for manned mission to ISS in early 2020

SpaceX could launch US astronauts to the International Space Station as early as next year if tests on the company's long-delayed Crew Dragon capsule prove conclusive, NASA Administrator Jim Bridenstine said Thursday.

Luca powers up for a spacewalk

Astronautics

Astronautics, and related astronautical engineering, is the theory and practice of navigation beyond the Earth's atmosphere. In other words, it is the science and technology of space flight.

The term astronautics was coined by analogy with aeronautics. As there is a certain degree of technology overlapping between the two fields, the term aerospace is often used to describe them both.

As with aeronautics, the restrictions of mass, temperatures, and external forces require that applications in space survive extreme conditions: high-grade vacuum, the radiation bombardment of interplanetary space, the magnetic belts of low Earth orbit. Space launch vehicles must withstand titanic forces, while satellites can experience huge variations in temperature in very brief periods. Extreme constraints on mass cause astronautical engineers to face the constant need to save mass in the design in order to maximize the actual payload that reaches orbit.
