Best Tools for Researching Space Stocks in 2026

No single tool covers everything about a space stock, so the useful question is which tool does which job. For primary records, use SEC EDGAR (filings), USAspending and SAM.gov (government contracts) and Launch Library 2 (launches). For convenience on top of those, there are catalyst calendars (Stock Catalysts, Catacal), a space-stock theme page (VCP Scanner), space-industry platforms (SpaceNexus), launch trackers (SpaceOdysseyHub) and Martian Alpha, which collects space-specific tools in one terminal. Descriptions below come from each tool's own pages as read on October 6, 2026. Features and prices change, so check before you rely on them. We make Martian Alpha, so read that entry with that in mind. This is research, not financial advice.

Quick map: which tool for which job#

Primary sources: free and authoritative#

These are where the numbers originate. Every other tool on this page is built on, or links back to, records like these.

• SEC EDGAR. Every public company's 10-Q, 10-K, 8-K and Form 4, plus Form D and S-1 filings for companies that are raising money or listing. It's free and authoritative, but it's a database, not a research workflow. Our filing-by-filing guide shows how to use it.
• USAspending and SAM.gov. USAspending describes itself as the official source for US government spending data; SAM.gov carries solicitations and awards. Together they show who is winning NASA, Space Force and DoD work. See our DoD space contracts guide.
• Launch Library 2. The Space Devs' launch API, used by several launch trackers. It's a data feed for developers rather than a finished website.

If you only use one thing from this page, use EDGAR.

Catalyst calendars#

A catalyst is a scheduled or newly reported event, such as earnings, a launch or a contract award. Two general calendars are worth knowing:

• Stock Catalysts (stockcatalysts.ai) describes itself as a catalyst calendar across hundreds of publicly traded companies, including examples such as a SpaceX launch. Each event gets an importance score from 0 to 100, filterable in the feed, and it emails a daily digest of newly added catalysts, with a watchlist option.
• Catacal (catacal.com) says it is free and updated daily. It lists earnings, IPOs, macro releases and lock-ups, adds AI "impact scores" and offers reminders and a weekly list of top catalysts.

Both are general-market tools, not space-specific. They're a good fit if you follow space stocks alongside other sectors. If you want launches, FAA and contract events in the same feed as earnings, you need a space-specific one.

Launch trackers#

• SpaceOdysseyHub (spaceodysseyhub.com/launches) shows a launch calendar with countdowns, a provider scoreboard with fleet success rates, cadence charts and cost-per-kilogram estimates. It states its launch counts come from Launch Library 2 and notes its own estimates and methodology on the page. Its focus is the industry and spaceflight, not stocks.
• Launch counts differ between trackers because of cut-off dates and what counts as a failure. Our launch success rate guide explains why, and how to compare rockets fairly.

Theme and screening pages#

• VCP Scanner (vcpscanner.com) has a "Space Stocks" theme page that ranks a basket of 31 companies by return and growth, with valuation and analyst-rating summaries and upcoming earnings. Its basket mixes pure-play space companies with large diversified companies, and the page says the composition is reviewed periodically; check the basket matches what you mean by "space stock".
• MarketBeat publishes recurring "space stocks to watch" lists generated from its stock screener. They're useful as a headline list, but they're lists, not a research workflow.

Space-industry platforms#

• SpaceNexus (spacenexus.us) is a platform for the space industry broadly: its own comparison page lists company profiles, news aggregation, satellite tracking, a launch database, engineering calculators, funding tracking, AI insights, regulatory tools, a jobs board, community features and API access. It states a Pro plan at $19.99 per month and says it aggregates 50+ data sources. It's aimed at people who work in the industry as well as investors, so it covers more than stocks. Check its site for current plans.

• Stock Titan (stocktitan.net) is a general-market news and SEC filings site. Its navigation lists a live news feed, a live filings feed with pages for Form 4, 8-K, 10-K, 10-Q, S-1 and other form types, stock themes including "Space & Satellite", a heatmap, rankings, short-interest lists and tiered tools. It is not space-specific, so it suits people who follow space stocks next to the rest of the market; I did not check its prices or limits.

• New Space Tracker (newspacetracker.com) is a directory of space organizations. Its homepage title reads "1,816 Space Companies and Agencies", and the site lists launch providers, rockets, a launch calendar, a Starlink tracker, upcoming IPOs, a company compare tool, news and an open CSV/JSON dataset. It is built for the industry rather than for stock research (as read October 12, 2026).

Martian Alpha#

Martian Alpha (martianalpha.com) is a research terminal for space stocks. This is what the site's free plan includes today: a sector dashboard and heat map, a CANSLIM screener (fixed factors), a launch calendar and rocket viewer, a Catalyst Feed and contract award ticker, company profiles with an AI Deep Dive (2 a week), AI research chat (5 a day), watchlist with price and news alerts (2 tickers), a constellation tracker, a launch reliability scorecard, a private company directory based on SEC Form D filings, a government contract explorer and an engineering toolkit. Paid plans run from $5 to $100 per month and add higher limits and tools such as insider (Form 4) alerts and an IPO and SPAC pipeline monitor; see the plans page for the exact split.

What it doesn't do: it has no cash runway figure or backlog column on company pages (our cash runway and backlog guides show the manual method), and it's not a replacement for reading the filings. Its pitch is narrower: the space-specific events and tools in one place, with links back to the sources. Try the Catalyst Feed, launch calendar or screener first; they're free.

At a glance (as read October 12, 2026)#

"Not listed" means the item does not appear on the pages I read, not that the product lacks it. Each row reflects the vendors' own pages on the date shown; check them before relying on this table.

How to choose#

1. Start from the question. "When is the next event?" is a calendar; "how much cash is left?" is a 10-Q.
2. Prefer tools that link to the source. A number you can't trace to a filing, release or launch record is a lead, not a fact.
3. Check the universe. A "space stocks" list may include large conglomerates or leave out small caps. See what's in it.
4. Check the date. Pages and counts go stale; look for an "as of" date.
5. Budget for overlap. Two calendars plus EDGAR is usually enough; more subscriptions rarely add information.

FAQ#

What is the best free tool for researching space stocks?#

For accuracy, SEC EDGAR, because the filings are the source for most other tools. For convenience, a free catalyst calendar or Martian Alpha's free plan can save time.

What are the alternatives to Martian Alpha for space stock research?#

Stock Titan for general news and filings feeds, New Space Tracker for an industry directory and launch data, SpaceNexus for a broader industry platform, and SEC EDGAR for the primary filings. The table above compares them as of October 12, 2026.

Is there a free launch calendar tied to space stocks?#

Several launch trackers are free, such as SpaceOdysseyHub, and Martian Alpha's launch calendar links launches to the listed companies involved. Launch Library 2 is the underlying data source for many of them.

Do I need a paid platform to research space stocks?#

Not necessarily. Filings, contract databases and launch records are free. Paid tools mainly save time or add limits and alerts; whether that's worth it depends on how often you use them.

How do I check if a space-stock list is reliable?#

Look at which companies are in it, when it was last reviewed, and whether each figure links to a filing or a dated source.

Is this a recommendation to buy any stock?#

No. It compares research tools and isn't investment advice.
