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.
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?

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 ...
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 ...
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 sketch out the foundations of a colony on Mars
EPFL scientists have mapped out the steps required to build a self-sustaining research base on Mars that would be habitable for the long term. Their work can help researchers set priorities for space programs exploring Mars ...
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, ...
A cosmic gorilla effect could blind the detection of aliens
A well-known experiment with young people bouncing a ball showed that observers focusing on counting the passes failed to detect a man in a gorilla suit crossing the screen. According to researchers at the University of Cádiz ...
Comet dust under the microscope
Comet dust from the Rosetta mission is providing insights into the origins of our solar system. A research project focusing on the dust, which is supported by the Austrian Science Fund FWF and being carried at the Space Research ...
