Expiring medications could pose challenge on long space missions

Medications used by astronauts on the International Space Station might not be good enough for a three-year journey to Mars. A new study led by Duke Health shows that over half of the medicines stocked in space—staples ...

Image: Orion spacecraft prepares for upcoming launch

Technicians lift NASA's Orion spacecraft out of the Final Assembly and System Testing cell on June 28, 2024. The integrated spacecraft, which will be used for the Artemis II mission to orbit the moon, has been undergoing ...

Robotic rover could support astronauts on moonwalks

Robotic companions are a mainstay of sci-fi series everywhere. From R2D2 to Johnny 5, these characters typically have a supporting role in the story and are helpful to their human companions. But what if they were integral ...

Human bodies mostly recover from space, tourist mission shows

How bad for your health is space travel? Answering this question will be crucial not just for astronauts aiming to go to Mars, but for a booming space tourism industry planning to blast anyone who can afford it into orbit.

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.
