Will there be a mission to that dwarf planet sedna?

Hello,

I know the distance is a long way 973 Astronomical units from the sun, I wasn't aware of it, a dwarf planet, until I read about Voyager 1 again about that spacecraft's distance from it within the region, but certainly some distance from it.

It would decades to get there, but that alone would be similar to the Pluto spacecraft several years ago now.


New Horizons (Principal Investigator: Dr. Alan Stern, SwRI): New Horizons flew past Pluto in 2015 and the Kuiper belt object (KBO) Arrokoth in 2019. In its second extended mission, New Horizons will continue to explore the distant solar system out to 63 astronomical units (AU) from Earth. The New Horizons spacecraft can potentially conduct multi-disciplinary observations of relevance to the solar system and NASA’s Heliophysics and Astrophysics Divisions. Additional details regarding New Horizons’ science plan will be provided at a later date.

This is on extension, but yes, it isn't going to be orbiting a planet anywhere near by. There isn't anything on the trajectory, at least nothing unknown.

That would be cool. If one of our boys would have turned out to be a girl, we would have named her Sedna. It ultimately won out over Easterbunny... :LOL:

If you are interested in a possible exploration of Trans-Neptunian objects, maybe have a read of
Exploration of trans-Neptunian objects using the Direct Fusion Drive.

The pdf is free to download. It shows ways to reach Pluto, Haumea, Makemake and Eris within 10 years with a direct fusion drive, using Deuterium fuel (and a little bit of He3). Unfortunately Sedna is not in the list, probably because is Aphelion is so far out.

I mean, as in NASA, I don't mean anything about Orbiter, I haven't used that program in a good several years now.

Like with the example of Voyager, the only reason it is where it is, is because of the planets. So I'm using that example, that would a probe be sent out there anytime in the decades ahead, I don't mean thirty years.

That file is very technical. I read about Sedna through Voyager on wikipedia.😉

I know, hehe

It sure is very far away. Likely for another chunk of rock and ice, one amongst billions. I think places like Europa are more promising in terms of scientific discoveries.

Could be good for propulsion reasons. Testing out a new chemical engine that would take a probe there as its destination. And so on.

Chemical engines we have today can easily send a probe to Sedna. Voyager I & II are even fast enough to escape the Sun gravitational well completely, actually they have entered interstellar space. The limitation usually comes from the mass of the spacecraft, else all you have to do is to get a bigger rocket.

The probes couldn't travel to Pluto. That is the point. They couldn't do anything without more thrust and fuel, and even then still need a power supply to keep transmitting.

Otherwise, they could travel through the oort cloud and there in half the travel time in order to leave. Why three centuries, and not fifty?
