The most complete plan for this was proposed by JPL's Slava Turyshev and team. It has been selected for Phase III of NASA Innovative Advanced Concepts. [0]

> In 2020, Turyshev presented his idea of Direct Multi-pixel Imaging and Spectroscopy of an Exoplanet with a Solar Gravitational Lens Mission. The lens could reconstruct the exoplanet image with ~25 km-scale surface resolution in 6 months of integration time, enough to see surface features and signs of habitability. His proposal was selected for the Phase III of the NASA Innovative Advanced Concepts. Turyshev proposes to use realistic-sized solar sails (~16 vanes of 10^3 m^2) to achieve the needed high velocity at perihelion (~150 km/sec), reaching 547 AU in 17 years.

> In 2023, a team of scientists led by Turychev proposed the Sundiver concept,[1] whereby a solar sail craft can serve as a modular platform for various instruments and missions, including rendezvous with other Sundivers for resupply, in a variety of different self-sustaining orbits reaching velocities of ~5-10 AU/yr.

Here is an interview with him laying out the entire plan.[2] It is the most interesting interview that I have seen in years, possibly ever.

The Wikipedia article uses the name "Slava". His homepage on JPL website too (https://science.jpl.nasa.gov/people/turyshev/) I opened a random paper of his from arxiv and there too he uses "Slava".

Would it be possible that Mr. Turyshev uses that name as his preferred name (at least when writing in English) and that we should just respect his decision?

This decision is forced by it being hard for most English speakers to pronounce Vyacheslav.

Sure, but is it his decision to make, and if yes - are we ok to respect it?

I'm from a slavic country myself and my name is almost impossible to pronounce correctly in English - but I continue to use it anyway. If he wanted to do that, he could have done it.

My name is "Pavel", and usually ask Americans to put the accent on the second syllable - which is incorrect, but they can't pronounce my name correctly anyway when they put the accent on the first syllable, and it sounds more wrong to me than the way I prefer to have it pronounced.

Apologies to all the other Pavels out there; I've been training everyone I've met to pronounce it wrong. But it's the way I prefer to be addressed.

Now I'm curious what the _right_ pronunciation is!

You can look it up on Youtube.
