Acta Astronautica is sponsored by the International Academy of Astronautics. Content is based on original contributions in all fields of basic, engineering, life and social space sciences and of space technology related to: The peaceful scientific exploration of space, Its exploitation for human welfare and progress; Conception, design, development and operation of space-borne and Earth-based systems. In addition to regular issues, the journal publishes selected proceedings of the annual International Astronautical Congress (IAC), transactions of the IAA and special issues on topics of current interest, such as microgravity, space station technology, geostationary orbits, and space economics. Other subject areas include satellite technology, space transportation and communications, space energy, power and propulsion, astrodynamics, extraterrestrial intelligence and Earth observations.
Habitat is designed to provide stay on the moon, sleeps two
(Phys.org)—People have felt the excitement of seeing their courageous space heroes embark from the Earth to the moon. Those same heroes went up because, beyond completing the journey, they hoped to—in one word— explore. ...

Working out in artificial gravity
Astronauts on the International Space Station (ISS) have a number of exercise options, including a mechanical bicycle bolted to the floor, a weightlifting machine strapped to the wall, and a strap-down treadmill. They spend ...
Environmental protection in outer space
Should regulations for environmental protection be valid beyond our solar system? Currently, extra-terrestrial forms of life are only deemed worth protecting if they can be scientifically investigated. But what about the ...
A radio search for artificial emissions from 'Oumuamua
It's the first time a visitor from another star system has been seen nearby. But what is it? An asteroid, a comet … or an alien artifact?
Seeding the Milky Way with life using 'Genesis missions'
When exploring other planets and celestial bodies, NASA missions are required to abide by the practice known as "planetary protection." This practice states that measures must be taken during the designing of a mission to ...
Exactly how we would send our first laser-powered probe to Alpha Centauri
The dream of traveling to another star system, and maybe even finding populated worlds there, is one that has preoccupied humanity for many generations. But it was not until the era of space exploration that scientists have ...
Scientists design conceptual asteroid deflector and evaluate it against massive potential threat
Lawrence Livermore National Laboratory (LLNL) scientists are part of a national planetary defense team that designed a conceptual spacecraft to deflect Earth-bound asteroids and evaluated whether it would be able to nudge ...
Scientists discover new way to prevent spacecraft errors
Scientists from the National Research Nuclear University MEPhI (Russia) and the Scientific Research Institute of System Analysis of the Russian Academy of Sciences have recently developed components for designing fault-tolerant ...
Batches of shoebox-sized satellites could improve estimates of Earth's reflected energy
A team of small, shoebox-sized satellites, flying in formation around the Earth, could estimate the planet's reflected energy with twice the accuracy of traditional monolith satellites, according to an MIT-led study published ...
Study explores options that optimize profit in broadband satellite constellations
Several large telecommunications companies have proposed plans to provide global broadband services by launching hundreds and even thousands of satellites into orbit. Although broadband for everyone sounds like a great idea, ...
