Space physicists at Umeå University, Sweden, develop measuring instruments for the spaceship Comet Interceptor. The vessel has been selected to be part of the European Space Agency's ESA program to target comets that have just entered our solar system. The launch will take place in 2028.

"We are part of the team that develops instruments with several sensors to measure electric and magnetic fields, as well as neutral and electrically charged particles" says Herbert Gunell, professor of physics at Umeå University. "Here in Umeå we contribute with modeling and simulations needed to design the instruments and plan the observations at the comet."

By studying comets, we can gain new knowledge about the origin of our . But, exploring new, completely pristine comets has so far been difficult. The comet needs to be discovered when it approaches the Sun the first time—and the time to plan for and launch a spacecraft becomes too short.

Technological advances now make such assignments possible. Comet Interceptor is a new kind of spacecraft. In 2028 it will be launched as a "co-passenger" to ESA's exoplanet exploration spacecraft Ariel. The Comet Interceptor will travel with Ariel to the so-called Sun-Earth Lagrange point L2, which is 1.5 million kilometers behind the Earth seen from the Sun. There the can lie still and wait for a suitable comet meeting. When a comet approaches the solar system, the vessel, which actually consists of three separate space probes, can be sent away and split to make fly-bys near the comet. Observations can thus be made from several points around the comet and give a 3-D perspective on the 's core and its gas, dust and plasma environment.

The Dust Field and Plasma instrument to fly on the Comet Interceptor spacecraft is being developed by a consortium of researchers in Belgium, France, Italy, Poland, the UK, Sweden, the Czech Republic and Germany. From Sweden, the Royal Institute of Technology in Stockholm, the Institute for Space Physics in Kiruna and in Uppsala, and Umeå University.

These spacecraft will provide an excellent test for the Electric Comet theory. It's almost as if that was the idea behind the mission. The likelihood is, however, their "primordial" comet will look just like the rest.

"Space physicists?" They're called "astrophysicists." This is a translation error.

This is actually a pretty good idea to make sure to get to such a new comet quickly.

They don't want to be confused with the typical plasma ignoramuses that pervade the astrophysicist community.

Lol. Rosetta did just that. You failed miserably.

You are merely describing yourself, and the rest of the EU idiots. None of whom are qualified plasma physicists. The electric comet woo was a predictable, but nonetheless hilarious, failure. 100% wrong. Of course, we didn't need Rosetta to tell us that. Missions since 1986 had already done that!

You will have jonesy eating out of your hand
A sensor to measure quasi neutral fields!

LOL! How is that dirty snowball working out?

Zero comets have been found that look like your guesswork.

That is just your ignorance of what we have known comets to look like since 1986. Stop listening to tossers like Thornhill, and do some research, woo boy. The Tempel 1 impactor blasted out thousands of tonnes of solid ice. Thereby ending your rock delusion there and then. 4th of July 2005.

Jun 25, 2019
So your dirty snowball guesswork failed in 1986, noted!

And your delusions about what was observed from Tempel is just more of your lies and obfuscation.

Quit lying dumbo. We had never been to a comet until 1986. The idea was to learn about them. That is what science does. What did we learn? That there was shed loads of water. 20 years before the liar Thornhill claimed there wasn't! And that, as predicted, a diamagnetic cavity formed, within which the magnetic field is ~ 0 nT. No electric woo! And a whole bunch of other stuff.
And what did we learn at Tempel 1? That thousands of tonnes of ice were ejected by the impact. Want the links to the papers? And that the crater left by the impact can not have been into rock.
And what about 67P? That the density is very low, as already known less stringently. The diamagnetic cavity was confirmed. The surface material is very weak. The thermal inertia is very low. I could go on....... in short, your woo has been debunked 1OO%.

Jun 25, 2019
Oh, and another observation, alongside the Tempel 1 ice ejection, that the liar Thornhill didn't bother to tell you about; shed loads of solid ice being ejected from Hartley 2 by CO2 jets! So much that they even got pretty pics of it, as well as the spectroscopic confirmation that it is, indeed, water ice;

Diamagnetic cavities are electric woo, created by the electrical properties of the comet while immersed within electric plasma.

And we have seen how water is created at these airless bodies, and get this, water freezes when it is cold...

Wrong, dumbo. Show me the maths. How are you making ice in the coma? Lol. Why is it not happening at asteroids? What are the quantities involved? Where are you getting H+ and O- from? Remember, the solar wind is getting nowhere near the comet when it is most active. Where is this written up?

You see, this is what happens when you have no idea about science. Stick to your faith-based mythology woo. You are out of your depth.

Jun 25, 2019
Oh, and by the way, for the hard of thinking, the D/H ratio of cometary water is waaaaaay different from the solar wind value. And we don't see O-. And the comet is too warm to create water on its surface. That is why it is restricted to permanently shadowed areas on the Moon. Look up the sublimation temperature of H2O. Look at the temperature maps for Hartley 2 and Tempel 1. Et boring cetera.
