The Tema Space Innovators ETF (NASA 9.48%) offers concentrated exposure to space infrastructure and exploration, and includes pre-IPO SpaceX shares. The U.S. Global Jets ETF (JETS 0.21%) provides a more mature, sector-specific play on the global airline industry.

JETS tracks the recovery and operations of global airlines, whereas NASA targets high-growth innovation in space-based data and launch technology across various geographies and market capitalizations.

What this means for investors
The Tema Space Innovators ETF (NASA) and the U.S. Global Jets ETF (JETS) offer very different approaches to investing in the aerospace industry. When it comes to choosing between them, the decision comes down to individual investor goals.
NASA is for investors seeking exposure to space stocks. The nascent space economy has been hot of late thanks to the successful Artemis mission to the moon, and the highly-anticipated public debut of SpaceX. This fund would be of particular interest to retail investors looking to own pre-IPO shares in SpaceX.
However, NASA is a new fund. It launched on March 30, 2026. This means there is little insight into the ETF’s long-term performance. Investing in the fund at this stage would be a risk, particularly since it is entirely reliant on the space sector.
JETS provides investors with an efficient way to gain exposure to the global airline industry. Because this fund has existed since 2015, it has a long history for investors to gauge performance. JETS delivered a one-year return of 24.69% as of June 5. It also provides a dividend for income-oriented investors.
