Tema Space Innovators ETF (NASA) experienced a significant 24-hour plunge of 5.30% during the night session, underperforming the broader market.

The sharp decline appears linked to cautious remarks from NASA Administrator Jared Isaacman, who stated in an interview that the orbital economy is "grossly overestimated." He further cautioned that without government involvement, it was unclear who would purchase commercial lunar landers, casting doubt on the near-term commercial viability of some space ventures.

These comments likely prompted investor concern regarding the growth prospects and profitability of companies within the space innovation sector, leading to selling pressure on the thematic ETF.
