NASA Wants to Build a Magnetic Force Field and a Deep Sleep Chamber For Astronauts on Mars
Posted by Quinn Sena in categories: habitats, space
A self-assembling space habitat, a deep sleep chamber to shuttle astronauts on long journeys, and a protective magnetic force field are the latest projects NASA is embarking on.
NASAâs Innovative Advanced Concept (NIAC) Program is responsible for funding futuristic space concepts that could, as NASA puts it, âchange the possible.â Itâs not enough to merely be a cool concept, thoughâprojects are also screened for technical plausibility. In its latest round of funding, NIACâs Phase II program has selected eight projects to move ahead. Among the most promising ones are three focusing on how to build livable future habitats in space.

Researchers shed new light on atomic âwave functionâ
Posted by Genevieve Klien in categories: biotech/medical, quantum physics, space
Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct observation. The new method gives information about the likelihood of finding atoms at specific locations in the system with unprecedented spatial resolution. With this technique, scientists can obtain details on a scale of tens of nanometersâsmaller than the width of a virus.
Experiments performed at the Joint Quantum Institute (JQI), a research partnership between the National Institute of Standards and Technology (NIST) and the University of Maryland, use an optical latticeâa web of laser light that suspends thousands of individual atomsâto determine the probability that an atom might be at any given location. Because each individual atom in the lattice behaves like all the others, a measurement on the entire group of atoms reveals the likelihood of an individual atom to be in a particular point in space.
Published in the journal Physical Review X, the JQI technique (and a similar technique published simultaneously by a group at the University of Chicago) can yield the likelihood of the atomsâ locations at well below the wavelength of the light used to illuminate the atomsâ50 times better than the limit of what optical microscopy can normally resolve.

Space Mining Could Ruin Our Solar System If We Donât Establish Protected Places Now, Researchers Warn
Posted by Quinn Sena in category: space
A new study wants to protect the solar system from runaway human industry by making 85% of extraterrestrial resources off-limits.
Right now Chandra is gazing at a galaxy cluster in Draco. Nearby is the famous Tadpole Galaxy, seen here with thousands of galaxies in the background! The Tadpoleâs tail of stars is over 280,000 light years long, stretched by gravity during a previous close encounter with another galaxy!

NASA To Put Woman On Moon By 2024; Commercial Space Will Play Major Role
Posted by Bruce Dorminey in category: space
NASA finally seems serious about a crewed lunar return; this time with the first female astronaut to walk on the Moonâs surface.
Using a special liquid, engineers are designing new treatments for spacesuits so that they can better resist puncturing from tiny meteorites and other hazards.
