Solar Eclipse’s Shadow on Earth

Most visible towards the upper side of the image, that is the moon’s shadow over Earth.


  On May 10, 2013, the sun experienced what’s called an annular eclipse — when the moon moves directly in front of the sun, but doesn’t obscure it completely. This leaves a thin, fiery ring, the annulus, visible around the outside. This eclipse was only visible from the South Pacific, along an approximately 100-mile-wide track that traverses Australia, Papua New Guinea, the Solomon Islands and the Gilbert Islands. Other areas in Australia and Indonesia saw a partial eclipse, in which the moon blocks a much smaller region of the sun.

  NASA’s Terra satellite didn’t observe the eclipse directly, but it did see the moon’s shadow darkening the region northeast of Australia including the Solomon Islands. This image was captured by Terra’s Moderate Resolution Imaging Spectroradiometer on May 9, 2013, at 23:30 UTC (7:30 p.m. EDT).

Awesome Lunar Mining Vehicle Concept Art

D.S.I Surveyor Vehicle

The third image in my own series of Lunar mining is this fun looking thing, the Surveyor Vehicle is one of the smallest vehicles used by the mining team and is considered a general purpose vehicle but it also has one very important task, it is tasked with moving ahead of the main mining fleet and surveying the areas to make sure the giant harvester and H3 transports are not met by impassible terrain.

These vehicles also double as general maintenance units outfitted with a robotic arm with multiple attachments and an assortment of tools and replacement equipment they can conduct repairs on drones, communication arrays, and even minor repairs on the larger transports.

With a top speed of 60 mph and advanced multi direction suspension they are often used by the mining staff during down time taking them out for joy rides.

D.S.I Heavy Harvester Platform

Two things inspired this monstrosity, one was the movie Moon where they have set up a mining operation on the moon to harvest Helium 3 (needed for fusion reactors) and the announcement from Deep Space Industries (D.S.I) that they are going to start mining asteroids and the Moon in the near future.

I thought that seeing as it’s on the Moon you wouldn’t really need to worry about things like pollution and noise so you can build them big and loud. So as part of a running series about strip mining the Moon bare I give you the H.H.P (Heavy Harvester Platform) this one is called Leviathan and is number 2 of a fleet of 10 that slowly move over the surface of the Moon at about 3 mph and rip up the surface extracting the Helium 3 in its on board processing plant. Smaller transports take the Helium 3 to nearby depots where it’s fired at the Earth in large containers.

It’s damn dirty as behind each machine is several miles of dust that takes some time to settle and also it leaves behind a trench about 20 metres deep, but damn does it look awesome… Also it has no brakes.

D.S.I Helium 3 Transport Vehicle

Continuing with my Lunar Helium 3 mining project this image shows the Helium 3 Transport Vehicle. Each one of the huge harvesting platforms has a fleet of 6 H3TV’s which can hold a huge amount of refined Helium 3 ferrying it between the constantly moving behemoths to the transport docks dotted around the Lunar surface. Each of these vehicles will make around 6 trips a day and a fully automated but still hold a small crew for safety and maintenance reasons.

Like the giant harvester these vehicles are fitted with polarising plating which prevents the course and dangerous Lunar dust from sticking to the hull and damaging components, despite these methods each vehicle has to undergo a total deep clean once every month to prevent massive systems failure, to make sure the Helium 3 keeps rolling in on time a stand by fleet of H3TV’s are located at each transport dock.

Fact: It takes the moon approximately 27 days (29 to make the full cycle) to make a revolution around the Earth. In the context of astronomy, a revolution is the motion of one body around another (like that of the moon revolving around the Earth). In many time zones, today, January 27th 2013 marks one such revolution.


  As the days go by, the moon will start to look different every day.
  
  The main phases of the moon are the New Moon, Full Moon, First Quarter, and Third Quarter.  The New Moon begins at the start of each month while the Full Moon happens near the end of the month.  The New Moon happens because the moon eventually orbits in between the earth and the sun.  This is called the “dark” side of the moon.
  
  The Full Moon means that the “light” side of the moon is visible to earth. When you see only half of the moon, you are usually seeing the first and third quarter moon phase.  When the moon is at a 90 degree angle and is at the point where the sunlight shines in the side of the moon. This creates a half-moon.
  
  The rest of the different phases are called the crescent and gibbous.  To make it easier to figure out which is which, crescent and gibbous also get either waxing or waning.  Waxing means that the moon is getting brighter while waning means that the moon is getting darker.

Penumbral Lunar Eclipse over Baku

A total penumbral eclipse is a lunar eclipse occurs when the moon becomes completely immersed in the penumbral cone of the Earth without touching the umbra.

The umbra, penumbra and antumbra are the names given to three distinct parts of a shadow, created by any light source. For a point source only the umbra is cast.

Gravity Map Reveals a Surprisingly Battered Lunar Surface


  The moon and other rocky bodies in the inner solar system were pounded by long-ago impacts far more violently than previously thought, two NASA spacecraft have found.

  NASA’s twin Grail probes have created an ultra-precise gravity map of the moon, revealing that its crust is almost completely pulverized. The surprising find suggests that Earth, Mercury, Venus and Mars endured a similar beating billions of years ago, researchers said.
  
  The discovery “really opens a window to this early stage of just what a violent place the surfaces of all terrestrial planets were early in their history,” Grail principal investigator Maria Zuber of MIT said during a press conference here today (Dec. 5) at the annual fall meeting of the American Geophyiscal Union.

A Quadruple Lunar Halo Over Spain

Sometimes falling ice crystals make the atmosphere into a giant lens causing arcs and halos to appear around the Sun or Moon.

Image Credit & Copyright: Dani Caxete

This past Saturday night was just such a time near Madrid, Spain, where a winter sky displayed not only a bright Moon but as many as four rare lunar halos. The brightest object, near the top of the above image, is the Moon. Light from the Moon refracts through tumbling hexagonal ice crystals into a 22 degree halo seen surrounding the Moon.

Elongating the 22 degree arc horizontally is a circumscribed halo caused by column ice crystals. More rare, some moonlight refracts through more distant tumbling ice crystals to form a (third) rainbow-like arc 46 degrees from the Moon and appearing here just above a picturesque winter landscape.

Furthermore, part of a whole 46 degree circular halo is also visible, so that an extremely rare — especially for the Moon — quadruple halo was actually imaged. The snow-capped trees in the foreground line the road Puerto de Navacerrada in the Sierra de Guadarrama mountain range near Madrid. Far in the background is a famous winter skyscape that includes Sirius, the belt of Orion, and Betelgeuse all visible between the inner and outer arcs. Halos and arcs typically last for minutes to hours, so if you do see one there should be time to invite family, friends or neighbors to share your unusual lensed vista of the sky.

Total Solar Eclipse and Minor Lunar Eclipse to Grace Nov. Skies

November’s a good month for celestial shadow play. Stargazers will get two eclipses in about as many weeks, the first a dazzling total solar eclipse that will showcase the sun’s corona approaching peak activity, and the second a subtler lunar eclipse that will be visible across much of the United States.

The theatrics start on Nov. 13, when residents of northeastern Australia get a false-start sunrise. Just an hour after the sun breaks the horizon in the coastal city of Cairns, it will be fully obscured by the moon, whose shadow will darken the sky and bring the stars back into view for 2 minutes there.

The only visible part of the sun during the total eclipse will be its glowing corona, or outer atmosphere, protruding around the moon’s silhouette.

“Occurring as [the eclipse] does within months of the expected solar max, the solar corona should take on a ‘wound up’ circular shape, with a high potential for tongues of pink nuclear fire leaping from the Sun’s edge,” said astronomer Robert Berman, who writes for Astronomy Magazine.
