No. It's just an eclipse of the Moon. We get them anyway. Passover falls on full Moon and eclipses of the Moon always happen at full Moon so that's not a huge coincidence.

The rest of this is from my article: September 24th, 2015 - Just Another Day In Space - Asteroid Flybys, "Blood Moons" And Armageddon Demystified - which I can of course copy here as I'm the author :).

The moon always goes red during lunar eclipse.
It's rather poetic actually. Our Moon goes red from the light of all the combined sunsets and dawns on the world at the time of the eclipse. At the time of eclipse, the Sun and Moon line up so that the red light shines on the Moon.

The ISS gets sixteen sunrises and sunsets every day for much of the year - if you like to watch them, a low Earth orbit is the place to be, every 45 minutes you'll see one or the other of them (though there are times of year when it is permanently in sunlight and you don't see them, around the summer solstice).


This is the light which turns an eclipsed moon red, as seen from the space station.

As seen from the Moon the Earth would look dark with a very fine red ring all the way around it because of all the light from the sunsets and sunrises.

We actually have a photograph of the Earth from the Moon taken by Surveyor 3. It's actually an animated gif here of several frames, in black and white
APOD: 2014 April 7 (thanks to Jeffrey Phillips in comment for alerting me to this :) )

And a short video by JAXA - not actually from the Moon but from lunar orbit.


We also have a short video of the sun going behind the Earth, as seen by the Apollo 12 crew, Conrad, Gordon and Bean, on their journey back to Earth from the Moon.

(click to show on youtube, this frame is 18 seconds into the video).

And Hana Gartstein, graphic artist from Israel, did a nice simulation of it here, adapting a photo of Earth taken on the Apollo 17 mission.

This would make the landscape go red in colour.
This painting of the Earth as seen from the Moon during an eclipse is by Lucien Rudaux, space artist, living in first half of the twentieth century.

Incidentally, this was painted long before anyone had ever visited the Moon. When most space artists were painting jagged mountains, he pointed out that the mountains were clearly rounded through a telescope, especially when silhouetted against the edge of the disk, writing: "If we reconstruct geometrically the outlines of certain lunar mountains from their observed appearance, we shall find that instead of being steep and jagged, they have quite gentle slopes and their summits are frequently flat or smoothly rounded."  - The first science artist to draw accurate pictures of Mars and the Moon

And here is a video simulation of a lunar eclipse from the Moon, by Ernie Wright, for NASA.
"In the early morning hours of April 15, 2014, the Moon enters the Earth’s shadow, creating a total lunar eclipse. When viewed from the Moon, as in this animation, the Earth hides the Sun. A red ring, the sum of all Earth’s sunrises and sunsets, lines the Earth’s limb and casts a ruddy light on the lunar landscape. With the darkness of the eclipse, the stars come out.

"The city lights of North and South America are visible on the night side of the Earth. The part of the Earth visible in this animation is the part where the lunar eclipse can be seen."

Nothing at all to do with blood. And this happens during every lunar eclipse.
You get these every year, often twice a year. You get lots of lunar eclipses, more than solar eclipses, because the Earth casts quite a large shadow and the Moon is comparatively small. And unlike solar eclipses, everyone on the hemisphere of the Earth facing the Moon sees the eclipse, if you go out to look at it at the right time. But it's easy to miss it because it happens at night. Always at full moon and you can look up the predictions to see when the next one is: List of 21st-century lunar eclipses

This is the September eclipse. which will be visible from Western Europe, Western Africa and the Americas

Simulated view of the night side of Earth during the lunar eclipse for 28th September 2015, as seen from the Moon - by Tomruen. Anyone living in this hemisphere will be able to see the lunar eclipse if the night is clear - if you live near the edges of this region you'll need a clear view to the horizon to see it. September 2015 lunar eclipse

And this animation shows what to expect by way of colour changes during the event:

The colour of the Moon varies, depending on the weather conditions on the Earth, so we can't say for sure, what colour it will be.

For some reason recently people have taken to calling a set of four lunar eclipses a blood Moon. But it's got no historical precedence. Just a new term that people have started to use recently.

It's called a "blood moon" when you have four lunar eclipses within six months. That last happened in 2004, and happens again in 2014-2015. For more on this, Blood Moon (wikipedia). And Home: Four Blood Moons: Total Lunar Eclipse Series Not a Sign of Apocalypse. And on Universe Today, The Science Behind the “Blood Moon Tetrad” and Why Lunar Eclipses Don’t Mean the End of the World,

It's so sad really, that the lunar eclipse, which is normally a matter of wonder, for amateur astronomers, has been reinterpreted in this way as a sign of an approaching apocalypse. And - there's no possible causal connection there. A lunar eclipse just arises when the Moon passes through the shadow of the Earth (something the ISS does 16 times a day)..
