Nasa to wake up New Horizons spacecraft for voyage into mysterious Third Zone

Nasa is to wake up its New Horizons spacecraft next month following a five month hibernation, ahead of a journey deeper into one of the most mysterious regions of the Solar System.
New Horizons, which captured incredible images of Pluto in July 2015, was powered down in April to conserve energy as it travelled through the Kuiper Belt, a vast region of icy debris which encircles the Sun and planets, also known as The Third Zone.
On September 11, the spacecraft will awaken for its 16 month journey to MU69, an ancient object which is thought to be one of the early building blocks of the Solar System.

Science fiction from the 1950's...
1952 to be precise. Would love to see one of these printed up in a Herge style chequerboard. Or would that be too close to Peenemunde?

Well, first you need to make science fun again. Things like those chemistry sets with real chemicals and such that you could buy when I was a kid are a thing of the past.



or



These sets were full of stuff that was dangerously cool and fun to experiment with. You actually learned stuff.

The modern equivalent, if you can even find one, is "safe" and full of harmless experiments that aren't nearly as much fun



Science used to be cool because you got involved and did it. That's gone today. Even in schools science is mostly book work and the teachers usually aren't well versed in any aspect of it.

I read a GED prep book made by several female PhD's in education. The science section was illiterate. They said (as one example) that a "turbine" (they meant generator in the commercial sense) generated electricity and that it consisted of two magnets connected by a wire. That was literally how they described an electrical generator.

It was completely wrong and they had no idea what they were talking about. That went for the whole section. It's not that every school teacher is that scientifically illiterate, but most are.

You make science fun by getting kids to do it at an early age. We don't do that today. There's the possibility someone might get an "owie" needing a band aid and sued for millions as a result so schools don't take the risk. Teachers don't need any real background in science and most state curricula is pretty lame in this area.

If you make science fun and interesting, kids will get involved. If their teachers have no knowledge or interest, then the kids won't either.

That varies quite a bit from country to another. Here all teachers have at least master's degree and all subject teachers are required to have master's degree - or expanded minor in the subject, minimum of 60 ECTS (for primary school) or 120 ECTS (for anything after it, like high school) - in the subject they are teaching. Which is about 1 or 2 years of full academic studies in the university. And then they are required to have certain amount of pedagogy studies as well... So here you wouldn't be encountering such issues.

Many US teachers have Master's degrees and such in the US too. But, a Master's in Education, at least in the US doesn't mean you've got any sort of background in what are now being called in jargon STEM (Science, Technology, Engineering, Math) subjects. In fact, I'd say the overwhelming majority are very light to almost ignorant of these subjects.

For example, I got to peruse this GED text written by three women with PhD's and Master's degrees in Education:



The science and technology section of the book wasn't just bad, it was illiterate. The authors literally had no idea what they were talking about. It wasn't just sloppy or vague, it was entirely wrong.
The stuff they had related to physics I think was the worst. They discussed electricity and the whole section was wrong! I'd have given them an F- maybe 10 or 20 points out of 100 if it were graded. They obviously did little or no research on the subject, and if they did they didn't understand any of what they looked at.
They discussed things nuclear too. Same thing. Horribly wrong and no understanding of the subject.

Yet, these supposedly "smart" and well-educated teachers are what we have teaching our kids STEM subjects through most of their K to 12 education. If the teacher has little knowledge or interest in these subjects, she's going to impart that lack of interest on the kids.

I used "she" for a reason. I can't speak on Finland, but in the US public education and teaching is one of the most gender biased occupations there is. About 85% of all US K to 12 teachers are women today. It's above 90% for K to 8. Yet, there is absolutely ZERO push to get more men into teaching and education.

If that situation were reversed the usual crowd of Leftists would be howling about how horribly biased that employment ratio is and demanding that schools hire more teachers, give women all sorts of incentives to get teaching degrees, etc. But, because it's an almost all female occupation? Nada.

What i tried to point out is that here for example grade 7 - 9 physics/chemistry teacher has had to have master's at either physics or chemistry, and then had to have the second one as well as pedagogy (education) as 'expanded' minor subjects. So here any subject teacher is quite capable in his or her field. On grades 10 to 12 (aka gymnasium) the demands are even more strict.

So here teachers know what they are talking about. And they also have quite a few connections in their field as well. For example in nuclear physics course we went to a nuclear power plant (incl. reactor hall, waste caves, etc.). And i didn't even go to a 'specialized' school.

Here only the generic teachers (who major in education) might be somewhat lacking in specific subjects however they only teach during the early education (usually just on grades 1 through 6) but then again their task is not just to teach the basics of the subjects but also (and primarily) to teach the students to learn and study by themselves. If that makes any sense to you.

Not in the US. In fact, having the education degree trumps everything else here. So, you have some person say that's got an MA or whatever in say physics and has worked in the field and industry that now wants to teach. He or she is told to go get their BA in education with x hours of classroom experience and maybe they'll be "qualified."

The result here is teachers that have lots of experience in the bureaucracy and systems of teaching but know $h!+ about the subjects they actually teach.

Same in a way applies here actually - it just seems to be handled in a bit different manner. The teacher training (and practice) for the subject teachers is part of the expanded minor of pedagogy that i discussed earlier.

There are some things left to make science fun again.

1. If you can find it, an electronic experiment set, those that Radio Shack used to have. Hobby Lobby still has science learning kits available on all subjects.

2. Model Rockets. You need access to a big field or a club that has one. You build real flying rockets from kits.

3. Space Engine. A universe simulator where you can explore the known and unknown universe. Pic is the Intersteller Black Hole.

4. Kerbal Space Program computer game. Help the little Kerbals develop their space program by building and flying their rockets. With mods, you can fly real historical missions.


And, of course, model kits.
