Our read on each fund

ETF.net Research

NASACTema Space Innovators ETF

ROKTAState Street SPDR S&P Kensho Final Frontiers ETF

In short

NASA It landed the ticker every space fund wanted. NASA is a concentrated, roughly 40-stock read on the space economy, from defense systems to space tourism, and it trades like a much older fund.

ROKT Most space funds stop at the atmosphere. ROKT plays both frontiers: rockets and satellites plus the hardware that explores the deep sea, wrapped in an AI-informed S&P Kensho index running since 2018.

Stated mandate

NASA The Fund seeks long-term growth through investments connected with space-related innovation, including areas such as defense systems and space tourism.

ROKT The fund seeks to track the S&P Kensho Final Frontiers Index, targeting companies whose products and services support innovation in outer-space and deep-sea exploration through an AI-informed, quantitative index methodology.

Why people hold it

NASA One ticker, the whole launchpad: about 40 names tied to space innovation, spanning defense systems through space tourism.
Charges 0.75% a year, right at the median for space ETFs, so the concentrated active approach costs no more than the category norm.
Very actively traded and already north of a billion in assets, so getting in and out is rarely the hard part.
Lands in the upper half of its space-fund peer group on our overall read, helped by how cleanly it trades.

ROKT 0.45% a year, the cheapest sticker in this cohort: ORBX runs 0.50%, while UFO, ARKX and NASA each charge 0.75%.
The index bolts the S&P Kensho Space Index onto the deep-sea exploration names from the Kensho Drones Index, so orbit and ocean floor arrive in one ticker.ssga.com
Trading since 2018 under the SPDR roof, and one of the strongest implementations in the space-theme group on cost, portfolio and staying power.
Roughly 40 stocks, refreshed on the index's annual reconstitution, with cash paid quarterly.ssga.com

Worth knowing

NASA Cheaper orbits exist: ROKT charges 0.45% and ORBX 0.50%, against 0.75% here.
A 2026 launch with about 40 holdings in a story-driven sector: thin history to judge, and single names carry real weight.
Built for long-term growth, not income. It has not paid a distribution.

ROKT Trades lightly next to mainstream ETFs and carries a modest asset base; wider bid-ask spreads are the usual trade-off at that size.
Two frontiers in roughly 40 names is a concentrated slice of the market that can move very differently from a broad index.
The deep-sea sleeve means this is not a pure space bet: part of the portfolio never leaves the water.ssga.com
