Best Data Terminals for Researching the Space Economy

Martian Alpha (martianalpha.com) is a research terminal for the space economy: space stocks, launches, contracts, filings and private space companies in one place, free to start. It is built for investors and analysts who want the listed company behind each launch, contract and filing. Orbital Intel, Orbit Alpha, Off Earth Data, SpaceNexus and New Space Tracker cover parts of the same ground from different angles, and general terminals such as Bloomberg and Koyfin cover the market but not the space-specific records. The table below compares them as read on November 1, 2026.

What counts as a data terminal for the space economy#

The space economy is more than stocks. Launches, spectrum filings, government awards and private funding rounds all move the companies, and each lives in a different public record. A useful terminal does three things: it joins those records to the company they affect, it shows the source, and it is dated. A general terminal does the first well for prices and fundamentals but has no view of a launch slip or a Space Force award, so researchers usually pair it with a space-specific one.

Martian Alpha#

Martian Alpha is the purpose-built option for space equities. What it has in one place:

• Launches tied to the stocks behind them. The launch calendar lists each upcoming launch with the listed provider or customer, and the launch reliability scorecard compares rockets on the same basis.
• The Space Ledger. Each company page shows recorded launch-date changes and how the stock moved after each launch, net of the S&P 500. The ledger is recorded by Martian Alpha as it happens, so it is not something you can rebuild after the fact.
• Federal contract awards by company in the contract awards view, sourced from public award records.
• Private companies beside public ones: the private-company directory built on SEC Form D filings, and the IPO pipeline.
• The catalyst feed, the screener and the State of Space report.

Limits: it is a young, independent product; the data views are for research, not advice, and it does not replace reading the filings. Several tools need a free account.

Orbital Intel#

Orbital Intel's homepage calls itself "The Bloomberg Terminal for the Space Economy" and its description says it tracks launch manifests, satellite constellations, funding rounds, company profiles and news across space companies globally. That is an industry-wide scope. I did not verify its pricing or how it ties launches to listed stocks.

Orbit Alpha#

Orbit Alpha describes itself as a free weekly newsletter and live dashboard covering space stocks, with prices, launches, earnings, SEC filings and government contracts. It is the closest in scope to Martian Alpha's stock focus. Not to be confused with Martian Alpha, AlphaSense, Seeking Alpha or Alpha Vantage, which are unrelated products.

Off Earth Data#

Off Earth Data describes its product as a terminal for space-economy intelligence: scored entities, signal indices, federal contract tracking and constellation tracking, with 40+ public space equities covered. Its own page says scores and exports require access. I did not verify its pricing or methodology.

SpaceNexus#

SpaceNexus describes itself as a space-industry intelligence platform with satellite tracking, launch monitoring, space-stock analysis and 430+ company profiles, free to start. It also has jobs, news and engineering tools, so it suits people working in the industry. For a side-by-side, see Martian Alpha vs SpaceNexus.

New Space Tracker#

A directory of space organizations with launches, IPO pages, a compare tool and open data. Useful for finding companies; it is not built around stock research. See also our best tools for researching space stocks.

General terminals: Bloomberg and Koyfin#

Bloomberg and Koyfin are strong on prices, fundamentals and estimates across every sector. Neither is organized around launches, constellations or space contracts, so a space investor typically uses one beside a space-specific tool. Check each vendor for current pricing.
