China's space programs open up to world
Beijing (XNA) Oct 24, 2018 -
When German scientists were conducting micro-gravity
experiments on China's recoverable satellite in the 1980s, Chinese space
engineer Tang Bochang was busy solving technical problems, while
carefully keeping Chinese secrets.
Tang joined the China Academy of Space Technology in 1970, the
same year China launched its first satellite. He has participated in
the development of returnable sate ...

Weighing asteroids and planets using pulsars
Bonn, Germany (SPX) Oct 24, 2018 -
A team of scientists from the `International Pulsar Timing
Array' consortium, led by researchers from the Max Planck Institute for
Radio Astronomy in Bonn, Germany, has used pulsar timing data to measure
the masses of the dwarf-planet Ceres and other asteroids. The result
for the mass of Ceres is 1.3% of the mass of the Earth's moon. The team
has also measured the masses of the major planets of ...

NASA seeks information for gateway cargo delivery services
Washington DC (SPX) Oct 24, 2018 -
NASA will lead the development of the Gateway, a permanent
spaceship orbiting the Moon, to serve as a home base for human and
robotic missions to the surface of the Moon and ultimately, Mars. The
first orbiting lunar laboratory will be a temporary home and office for
astronauts for up to three months at a time, with cargo deliveries
likely scheduled when crew are not present.
The agency is ...

Minerals of the world, unite
Paris (ESA) Oct 22, 2018 -
Imagine you are on Mars and you stumble upon an
interesting rock. The colours, the shape of the crystals and the place
where you find it all tell you: there is more to it than meets the eye.
Tool in hand, you analyse how light scatters through it. Seconds later
you read the following description on the screen:
Jarosite is a potassium and iron bearing hydrated
sulphate. It crystallises with ...

Europa plume sites lack expected heat signatures
Tucson AZ (SPX) Oct 24, 2018 -
The study of two potential plume sites on Jupiter's
moon Europa has shown a lack of expected hotspot signatures, unlike
Enceladus where plumes have a very clear and obvious temperature
signature, research by Planetary Science Institute Senior Scientist
Julie Rathbun shows.
"We searched through the available Galileo thermal
data at the locations proposed as the sites of potential plumes. Re ...

Dellingr: the little CubeSat that could
Washington DC (SPX) Oct 24, 2018 -
Zipping through the sky 250 miles up is a
shoebox-sized bundle of detectors and electronics named Dellingr. The
namesake of the mythological Norse god of the dawn, Dellingr is among a
new breed of spacecraft known as a CubeSat.
These small satellites, measured in standardized
10-by-10-by-10 cubic centimeter units, weigh no more than a few pounds -
bearing little resemblance to the larger, ...

Caltech mom wins Nobel Prize, son is JPL Mars flight tech
Pasadena CA (JPL) Oct 18, 2018 -
"What the heck does Mom want? Oh, Mom probably
doesn't understand the time difference, she's in Dallas right now and is
probably still thinking it's California time...maybe she just wants me
to go check on her cats..." A litany of mundane explanations ran through
James Bailey's bleary mind at 3:23 a.m. on October 3 when he was
awakened from a deep sleep by three phone calls from his mother's cel

University for Science and Technology (KAUST), astronomers from the
Paris Observatory and the National Astronomical Observatory of Japan
(NAOJ), in collaboration with NVIDIA, is taking the search for habitable
planets and observation of first epoch galaxies to the next level.

UK-led Space Technology on BepiColombo Mission to Mercury
Leicester UK (SPX) Oct 22, 2018 -
As the BepiColombo spacecraft sets off
on its seven year journey to explore the strange world of Mercury this
week, it will be carrying a piece of cutting-edge technology developed
and built by UK scientists - and will represent a first for planetary
science.
The BepiColombo mission is a two
spacecraft mission, and a partnership between the European Space Agency
(ESA) and the Japanese Aero ...

Discovering a previously unknown role for a source of magnetic fields
Plainsboro NJ (SPX) Oct 22, 2018 -
Magnetic forces ripple throughout the
universe, from the fields surrounding planets to the gasses filling
galaxies, and can be launched by a phenomenon called the Biermann
battery effect.
Now scientists at the U.S. Department
of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found
that this phenomenon may not only generate magnetic fields, but can
sever them to trigger magn ...

Ultra-close stars discovered inside a planetary nebula
London, UK (SPX) Oct 24, 2018 -
An international team of astronomers
have discovered two stars in a binary pair that complete an orbit
around each other in a little over three hours, residing in the
planetary nebula M3-1. Remarkably, the stars could drive a nova
explosion, an entirely unexpected event based on our current
understanding of binary star evolution. The team, led by David Jones of
the Instituto Astrofisica de Canar ...

Giant planets around young star raise questions about how planets form
Boston MA (SPX) Oct 22, 2018 -
Researchers have identified a
young star with four Jupiter and Saturn-sized planets in orbit around
it, the first time that so many massive planets have been detected in
such a young system.
The system has also set a new
record for the most extreme range of orbits yet observed: the outermost
planet is more than a thousand times further from the star than the
innermost one, which raises int ...

Plan developed to characterize and identify ocean worlds
Tucson AZ (SPX) Oct 24, 2018 -
Strategies to identify and

Boulder engineers have developed a 3D printing technique that allows for
localized control of an object's firmness, opening up new biomedical
avenues that could one day include artificial arteries and organ tissue.
The study, which was
recently published in the journal Nature Communications, outlines a
layer-by-layer printing method that features fine-grain, programm ...

Understanding the building blocks for an electronic brain
Groningen, Netherlands (SPX) Oct 23, 2018 -
Computer bits are
binary, with a value of 0 or 1. By contrast, neurons in the brain can
have all kinds of different internal states, depending on the input that
they received. This allows the brain to process information in a more
energy-efficient manner than a computer.
University of Groningen
(UG) physicists are working on memristors, resistors with a memory, made
from niobium-doped stro ...

NASA watches airglow, the colors of the upper atmospheric winds
Greenbelt MD (SPX) Oct 24, 2018 -
What does our planet
look like from space? Most are familiar with beloved images of the blue
marble or pale blue dot - Earth from 18,000 and 3.7 billion miles away,
respectively. But closer to home, at the boundary between Earth and
space, you might encounter an unfamiliar sight. If you were to peer down
on Earth from just 300 miles above the surface, near the orbit of the
International Space St ...

Tempur-Pedic Mattress Comparison The
Temperflow? uses a patent pending technology that allows body heat to
ventilate out the mattress, while cooler air can flow back into the
mattress. See www.Temperflow.com
for more information about how their technology works. Or read our
comparison report on two different memory foam mattress products.
