Upon its release, Live from Space received generally positive reviews from music critics. Marcus J. Moore of HipHopDX gave the album three and a half stars out of five, saying "Ultimately, this album faces the same shortcoming as most live recordings: that you can’t truly appreciate the music until you’ve seen it performed. There’s no way to see the fans’ faces or feel their adulation when their favorite songs drop. You can’t feel the stadium rattle or watch the band actively simulate Miller’s catalog. Live from Space isn’t that visual, so the live tracks quickly lose steam after a few listens. It shouldn’t dissipate Miller’s momentum this year. If anything, it puts a nice ribbon atop the rapper’s valiant comeback." Chayne Japal of Exclaim! gave the album a six out of ten, saying "The pride and effort Mac and Syd's boys brought to the stage should be commended, but for the most part, the songs included on this album, as recordings, didn't need or receive any improvements, nor are they old enough to need updating. The glowing exception is the touching rendition of "Youforia" that swaps the douche-esque Mike Posner vibe of the original for a stripped-down, vulnerable performance that is another example of Mac's versatility."
