This is a mischaracterization. Mark Kelly voted against the “One Big Beautiful Bill Act” primarily because of its cuts to Medicaid and food assistance programs, not to defund NASA or the Artemis mission.
The bill included nearly $10 billion for NASA programs, with $4 billion directed to Artemis missions IV and V. Kelly has otherwise been a consistent supporter of space funding—he voted yes on a spending bill that allocated $24 billion to NASA this year.
