You remember the Apollo moon landings, someone tells you he envies you for that. What you do answer?

Good points indeed, but it seems they were telling the truth this time: they really will manage to get further from Earth than anybody ever did before, as other Dopers have calculated:

Back to the Moon! Artemis program follow along (it's finally happening!)

Not precise, but this page Moon Distance Calculator – How Close is Moon to Earth? shows apogee at 404,970 km on Apr 7, the flyby is Apr 6, so I don’t think anybodies pulling a fast one on farthest ever from Earth. Not at exact apogee, but should easily surpass the 400,041.

Back to the Moon! Artemis program follow along (it's finally happening!)

Apparently, the apogee will be on April 6th (calculator). So something like 405000 km, plus the swing from the free-return trajectory which (Mistral tells me) will take them 7600 km beyond the Moon.

Which, together with this:

The Guinnes Book of Records claims:

The highest altitude reached by humans is 400,041 km (248,573 mi), achieved by American astronauts James Lovell, Fred Haise and John Swigert in the severely damaged Apollo 13 spacecraft. The record-breaking flight was made between 11 and 17 April 1970 from the Kennedy Space Center in Florida, USA, and reached its farthest point from Earth at 00:33 UTC on 15 April, during their free-return loop around the far side of the Moon.

makes it a record.
And for what? Just to come back almost immediately
