Last week NASA InSight put more constraints on Mars' innards. The core is molten, which we knew; blanketing it, is a sheath of melted silicate. Glass, I guess.
Anyway ToughSF calculated how to restart this dynamo: 2e28 joules. 195 billion B41 fusion bombs
, down the mohole. Um.
Better ideas come from the comments: lensing, for about an hour and a half; or pushing asteroids into an elliptic orbit. That latter might start with Phobos which is, you know, already there, and we gotta get rid of it anyway. CybertechDan is more thinking a hundred km diameter Luna-like; Phobos is only eleven. So just move a S-type rock that's in the 90s km diameter down to intersect Mars and crash Phobos... bro.
Apparently this is a slow day for news.
