Using deep neural networks to explore chemical space
Expert Opinion on Drug Discovery, 2021The popularity and success of advanced AI methods like deep neural networks has led to novel ways for exploring chemical space. Their opaque nature poses challenges for model evaluation regarding novelty, uniqueness, and distribution of the chemical space covered.

Exploring and Exploiting Deep Ocean Space
2021Jules Verne’s life was framed by the second phase of the British Industrial Revolution. In his nineteenth-century world, a transition to steam occurred. It was a time of rapid technological developments and explorations of every corner of the Earth’s surface. Then the world population clock ticked slowly and was well below 1.3 billion. Today, more than

Cryogenic air purification for deep space exploration
Journal of Space Safety Engineering, 2021Abstract Deep space exploration and settlement represents a new frontier for the progress of mankind. From the first stratospheric flight to the Apollo missions, to the International Space Station and in the near future sustainable life on the moon, the occupancy and duration of flights have risen dramatically. This has put increasing demands on life

Self-reconstruction Space Cellular Robot for Deep Space Exploration
2018 International Computers, Signals and Systems Conference (ICOMSSC), 2018In view of the changeful topography of the surface of the extraterrestrial planet, this paper presents a detection robot (Cell-robot) based on space cellular robotics system, which is in a complex unstructured environment. Cell-M cells can be restructured to form a more powerful assembly robot by connecting to other cell modules independently.

Deep space flight of Hayabusa asteroid explorer
SPIE Proceedings, 2008The Hayabusa spacecraft rendezvoused with the asteroid Itokawa in 2005 after the powered flight in the deep space by the μ10 cathode-less electron cyclotron resonance ion engines. Though the spacecraft was seriously damaged after the successful soft-landing and lift-off, the xenon cold gas jets from the ion engines rescued it.

Human Space Exploration in the “Deep Space Proving Grounds”
2016Freeman Dyson once said “there is nothing so great or so crazy that a technological society cannot be moved to do, provided that it is physically possible.” He is one of the few surviving giants among visionaries from the space race of the 1960s. In his book Disturbing the Universe, he presents heretical ideas, such as space colonisation and the ...

Testing autonomous systems for deep space exploration
1998 IEEE Aerospace Conference Proceedings (Cat. No.98TH8339), 2002NASA is moving into an era of Increasing spacecraft autonomy. However, before autonomy can be routinely utilized, we must develop techniques for providing assurance that the system will perform correctly in flight. We describe why autonomous systems require advanced verification techniques, and offer some management and technical techniques for ...

New Approaches for Human Deep-Space Exploration
The Journal of the Astronautical Sciences, 2013We are undertaking a Russian-American study of orbital options to extend human exploration beyond the Moon’s orbit. For a viable program, an international collaboration (as now for the ISS) and reusable spacecraft will be needed. With reusable spacecraft, high-energy Earth orbits can be drastically modified with lunar swingbys and small maneuvers near ...

A reusable system for deep-space exploration
Journal of Spacecraft and Rockets, 1970If nuclear-rocke t propellant (hydrogen) can be found on the moon, the proposed reusable deep-space transportation system appears highly attractive for Earth-moon transportation and exploration of the near planets. For planetary missions, powered Earth swingby for departure and return permits system capabilities substantially beyond any previously ...
