Carnival of Space # 286 Light pollution special edition here @ LINKS THROUGH SPACE


(Images: International Dark-Sky Assocation. When the eastern power grid failed, from Ontario to New York City, in August 2003, it revealed something many city dwellers had never seen: from horizon to horizon, a sky full of stars. Then the power came back on.)
Welcome to Links Through Space, astronomy for everyone.
This is the blog of our Astronomy Club here in Kustavi, Finland
We write/post news about space related topics and we showcase our Astrophotos and Timelapses.
Our blog is a way for you to follow Space/Astronomy news and find new links through the Internet about Space and astronomy.
So here we have it, Ladies and Gentlemen!
Links Through Space is honored to declare the 286th Carnival of Space live from Kustavi Finland.
 OPEN!
This Carnival of space #286 includes a Light pollution special edition.
Links Through Space has an article on Light pollution. A view of light pollution in astronomy these days.
Please visit the links in the article on light pollution carefully and participate actively to the many programs and events.
Thank You!

Space Missions
Planetary Resources has an interesting update, video and press release. In the accompanying video, you can see one of our full scale Arkyd-100 mechanical prototypes. The Arkyd-100 is our space telescope and technology demonstrator for our Arkyd Series prospecting missions.

Deep Space Industries is a competitor to Planetary Resources which also is working towards space asteroid mining. Deep Space Industries plans to launch a fleet of prospecting spacecraft in 2015, then begin harvesting metals and water from near-Earth asteroids within a decade or so. Such work could make it possible to build and refuel spacecraft far above our planet's surface, thus helping our species get a foothold in the final frontier.

Russia’s Federal Space Agency (Roscosmos) has begun the process of designing and building a replacement for its ageing Soyuz rocket and space capsule system, with the aim of putting it into operation by 2020. The Russian budget for a new rocket and capsule has been set at 2.1 trillion rubles (£43 billion), according to the programme details on the Roscomos website. The new "energy transportation module with a promising propulsion installation that will be ready for testing by 2018" is intended for "detailed study of the Moon," using "an entirely new class of interplanetary travel technology.

NASA has new study of nuclear thermal rockets. An initial pre-conceptual CERMET Nuclear Thermal Propulsion reactor system is investigated within this paper. Reactor configurations are investigated where the fuel consists of 60 vol.% UO2 and 40 vol.% W where the UO2 consists of Gd2O3 concentrations of 5 and 10 mol.%.Gd2O3. The fuel configuration consisting of 5 mol.% UO2 was found to have a total mass of 2761 kg and a thrust to weight ratio of 4.10 and required a coolant channel surface area to fueled volume ratio of approximately 15.0 in order to keep the centerline temperature below 3000 K. The configuration consisting of 10 mol.% Gd2O3 required a surface area to volume ratio of approximately 12.2 to cool the reactor to a peak temperature of 3000 K and had a total mass of 3200 kg and a thrust to weight ratio of 3.54. It is not known yet what concentration of Gd2O3 is required to maintain fuel stability at 3000 K; however, both reactors offer the potential for operations at 25,000 lbf and and at a specific impulse which may range from 900 to 950 seconds. This compares to the 1960s 850 seconds of the old NERVA project, where actual hardware was produced and tested.

This week marks a milestone in the openFITS collection as we've nearly doubled the amount of data offered up for curious minds to explore and create their own images. We now offer a collection of 17 data sets covering supernova remnantsgalaxiesneutron stars, pulsars, and the supermassive black hole at the center of our very own galaxy, the Milky Way.

Earth is the only place we know having lights turned into Light pollution. The Main Topic this week is Light pollution and Links Through Space has an article on effects of light pollution around the world.
Read this great article and comment please, we surely want to know what is going on around your local area.

Choose your lighting, the eye adapts well to the darkness.
30-45 minutes your eyesight will be adequate in night time.

A discussion of some images from the Mars Reconnaissance Orbiter that resemble dark plants growing on Mars and a set of spiders. We explain how seasonal changes due to dry-ice sublimating can explain the strange pictures.

To conclude The Carnival of Space #286 is all about the future of us seeing, exploring, feeling the future of space as we call it. Universe as it is.
 The National Space Society (NSS) wants to give you a truly inspiring and informative look at the future of space development.  NSS is the leading grassroots space advocacy group in the U.S., and fights for both space exploration and commercial development of space.   We believe in a bright future with humanity charging out into the solar system.

 So here you have it! All the thrills and excitements of the Astronomy/Space community.
The Carnival of Space #286.
If you run a space/astronomy related blog, and would like to get more awareness, participate in the Carnival of Space. Every week, a different webmaster or blogger hosts the carnival, showcasing articles written on the topic of space. It’s a great way to get to know the community, and to help your writing reach a wider audience. If you’d like to be a host for the carnival, please send email to carnivalofspace@gmail.com
