The Japanese probe, named Akatsuki, has gone dark. Mission control thinks that the craft may have lost its pointing with Earth and are working to reestablish contact.

The probe got off to a slippery start. It launched on a Japanese rocket in 2010, then a burn to lower its orbit fired for only three minutes instead of twelve. This put it in an orbit around the Sun, instead of Venus. After much research and study, they were able to get it into the orbit of Venus by venting a large quantity of fuel oxidizer. The orbiter began "taking data in 2016 about the planet and its atmosphere. In 2018, the mission's lifetime was extended, and it has continued to collect data until this spring."

There are two solar probes that occasionally slingshot around Venus for a gravity assist to boost their orbits, but their scientific gazing is focused on the Sun.

As it happens, a woman on Russet's crew is a specialist and somewhat of a noted expert on Venus and studies it frequently. It's a difficult planet to study as the window that it's above the horizon is very small.

IT SURVIVED ITS THIRD LUNAR NIGHT!

Now, this is a probe/lander that HAS NO HEATERS. It was not expected to survive ONE lunar night, much less two. And now it has survived THREE!

The little enginespace probe that could!

It is degrading, of course. Batteries and sensors are failing. But what do you expect? It is so far beyond its operational lifetime and parameters, this is inevitable. But the fact that it is not totally dead is simply amazing.

Now will we see it come back to life after the fourth night? Time will tell.

I recommend clicking on the comments section, they're quite amusing.

This is pretty spectacular. It suffered a landing mishap when one of its engines failed and it toppled over to land on its face. Still, it got useful data - and the landing itself was quite a success in that it landed within a 100 meter target where it was supposed to. For an unmanned probe launched over 200,000 miles away, that's pretty much a bulls eye!

And then night came. It wasn't designed to survive the night, and the ground crew were resigned to that.

But when the next lunar day came, two weeks later, it woke up!

In the words of Monty Python, there was much rejoicing.

But then the next lunar night arrived, and the ground crew expected that to be the end of the probe.

Then two weeks later, the next lunar day arrived, and it woke up again!

It's not in that great of shape as it has been taking a beating with the lunar nights at over 200 degrees below zero Fahrenheit and the lunar days over 200 degrees above, but as I said before: they must have partnered with Timex because it's taking a licking and still ticking!

The failure has been discovered: its altimeter failed! That's kind of bad when you're trying to land a rocket.

They tried to coopt a NASA experiment that was on-board, but it was only partially successful. The lander believed that "it was about 100 meters higher relative to the Moon than it actually was. So instead of touching down with a vertical velocity of just 1 meter per second and no lateral movement, Odysseus was coming down three times faster and with a lateral speed of 2 meters per second."

Whoops! The hard hit and the lateral skid caused one of the landing legs to snap, which resulted on its tipping over on its side. Still, as they say when landing aircraft, any landing you can walk away from!

The other news is that the Japanese lander, SLIM, woke up after a lunar night! Keep in mind that the moon alternates between extremely hot and extremely cold in its day/night cycle. The night is -133c, or -208f! Pretty darn brisk! These probes aren't typically designed to handle that level of cold. The Russian probes that did had radioactive thermal generators and a clamshell covering so they could turtle-up when it got dark and hunker down, then open up again when it warmed up. SLIM? Not so much. Like the Indian probe, it was designed for a short life in the sun, then they expected it to die. The Indian probe did not survive the cold. But apparently SLIM did!

After the night cycle ended, they sent a ping to the probe and it responded! While the rovers it dispersed are probably dead, the lander itself has cameras and sent back some pix. They powered it down to standby as it's pretty hot right now (over 200f!) but the fact that it survived and they will still get some data from it is pretty awesome.

It will be interesting to see how many day/night cycles it will survive. They must have have parts of it built by Timex and Toyota. ;-)

The arsonist, for reasons currently unknown, burst into the offices and doused the building with gasoline, shouting "Drop dead!", before igniting it. Police found knives in the wreckage. People were trapped inside, some fled up to the roof of the structure. He had just previously bought 9 gallons of gas from a nearby station.

The attacker survived but was - hopefully - badly burned and is in hospital, so with luck officials will be able to find out just WTF happened and why he did it. Apparently the man may have thought the studio stole an idea of his without credit or compensation or something, hard to say based on this report.

According to the BBC report, some 36 people are in hospital, many in critical condition.

Kyoto Animation is not a controversial studio. Their animation is not violent or sexual, they make nice, pleasant anime. It is quite a baffling event. I'm not familiar with their content, but they're quite popular. One of their innovations was paying animators a salary rather than a per-cell wage, making for a more relaxed working environment.

Also from the article, "Kyoto Animation, known as KyoAni, was founded in 1981 and has produced popular animation shows including K-On and The Melancholy of Haruhi Suzumiya.

The studio also released a standalone feature anime A Silent Voice in 2016.

One of KyoAni's series, Violet Evergarden, was picked up by Netflix for a global market."

A GoFundMe campaign has started and raised over $300,000 in six hours. It was the first successful anime studio outside of Tokyo. They also publish high school life manga.

This is one of the largest mass casualty events in Japan since World War Two.

This guy (gaijin) goes to Japan, gets very drunk on his birthday, and gets into an altercation with a taxi driver. Huge misunderstandings for lots of reasons, the driver ends up injured, the gaijin ends up in prison.

The Japanese legal system does not sound like a very fun thing.

This is the first part of a series, I haven't delved deeper into it yet: http://www.stippy.com/japan-life/gaijin-in-a-japanese-prison-1/
