New work is being done to explore a deep space robotic mission.

A unified view of our heliosphere could be captured by this project. It sounds like it's hard-to-do.

One booster of choice for the mission could be NASA's Space Launch System.

There is a mission idea that is gaining traction.

Long overdue

It's not about where we are. The journey out there is what it is about. It is a journey that has been in the works for a long time.

Today's technology can pave the way, scientifically, technically, andprogrammatically for more ambitious future journeys, and to conquer more go-getting science goals, as shown in a recent study.

With the new class of super heavy-lift launch vehicles in the works, the Interstellar Probe mission can now become a reality.

The team put in a lot of work to make sure the study was thorough and detailed. We are looking forward to what our colleagues with the Solar and Space physics Decadal Survey have to say.

Relay race

Interstellar probe is a decades-long mission to reach several hundreds ofAU away from Earth while providing new unified, measurements of the conditions throughout the heliosphere and through the heliosheath

It will take up the relay race that began with Pioneer 10, followed by the other two.

The Space Launch System Block 2 cargo version could be used to carry a 3rd and 4th stage rocket booster. The solar system's escape speeds should be twice as high as that of the first one.

It has been a topic of discussion for almost 50 years. Further progress requires a new initiative with the 40-year-old Voyagers closing out their operational lifetimes as their power supplies dwindle.

Furthest presence

Since Pioneer 10 was launched in 1972, the human race has traveled farther and farther from the Sun. McNutt told Space.com that there has been a "furthest presence" in the solar system since then.

Sometime in the next 10 years, the Voyagers will stop talking. It's a matter of physics, engineering and the cold equations.

Will that mean a retreat from pushing the bounds of knowledge or a handover of the baton to a different player? McNutt said that we make the history of future generations by our actions. Who are we going to deprive the next generation of? Why right now? Rather, why not now?

Vantage point

According to Paul Gilster, the creative drive behind the website Centauri Dreams, Interstellar Probe is an outstanding idea. It's a mission that could take us to 1000AU in 50 years, he said, and give us a view of the heliosphere.

It is a deep space mission with implications for future exploration. Gilster told Space.com that learning more about the heliosphere would tell us more about the solar wind and its interactions with the outside world.

Gilster said that Interstellar probe needs to be seen.

At some point in the future, there will be two NASA probes, one of which will join the other.

The Local Interstellar Medium was not built to study space outside of our solar system. Gilster said that Interstellar probe would be the first mission designed with this in mind.

Voyager plus?

Is Interstellar Probe just "Voyager Plus?" is a question Gilster hears a lot. Who would want to wait 50 years for data? He said these assumptions are not correct.

Interstellar probe is a brand new class of mission that is designed to operate beyond the Kuiper Belt. The 50 year period is a goal for 1000AU and is based on optimistic ideas about how to find the necessary "delta-V" - the amount of effort that is required to change from one trajectory to another.

Gilster said that science will be done the whole way. We will be learning a lot more about the nature of our Sun's travel through the galaxy than the Voyagers could tell us. We will have lots of targets for study as Interstellar probe moves through the outer solar system.

Deep space precursor

Gilster believes that humankind will eventually want to use technology of the future to explore the Oort Cloud of comets.

Gilster said that it was fitting that the first probe to leave the solar system should be led by a veteran. I wish he and his team at APL good luck as they go through the approval process.

The team's publication "Interstellar probe -Destination: Universe (opens in new tab)" gives a detailed look at how this mission could be accomplished.
