Built for space professionals
SpaceNexus is a comprehensive space industry intelligence platform that provides real-time data on satellite tracking, launch schedules, space stocks, regulatory compliance, and 530+ company profiles across 40+ modules.
Yes! Our Explorer plan is completely free and includes access to mission countdowns, basic news feeds, the full satellite catalog, launch tracking, launch alerts (up to 10 alert rules by email, push and in-app with a free account; launch emails and the calendar feed need no account), 3 business alert rules on news, stocks, filings, contracts, funding, leadership moves, hiring changes and space weather, the Space Tycoon game, and every news story, article and analysis with no daily limit.
Your free 14-day Professional trial starts the first time you use a Professional feature: a 4th business alert rule, a Slack or Discord webhook, or a Professional API key. No card needed. It lasts 14 days and includes everything in Professional, with the Professional API capped at 1,000 calls in total during the trial. One trial per account. When it ends your account moves to the free plan on its own; you do not need to do anything. Signed in, you can also start it yourself from this page.
Professional ($19.99/month) is for people who use SpaceNexus for work: alert rules on news keywords, daily stock closes, regulatory filings, federal contract awards, funding rounds and geomagnetic storms (up to 50 rules), Slack or Discord webhooks, an unlimited company watchlist, API access (25,000 requests a month) and no display ads (clearly labelled sponsorships and partner articles can still appear on some pages). Everything else on the site (trackers, launch alerts, the funding-round database, patents, procurement, a sample of the sourced supply-chain map, the regulatory calendar, the compliance hub, the customer-discovery database, AI insights, Space Score and the game) is free for everyone, on purpose.
Yes. Professional is billed monthly or annually with no long-term commitment; cancel anytime and keep access until the end of the period you paid for. SpaceNexus Research ($399/year, 5 named seats) is an annual subscription: cancelling stops the renewal, and access continues to the end of the paid year.
Yes. Research has no free trial, so instead: ask for a refund within 30 days of your first Research payment and we refund the full amount. Write to us through the contact page and choose the subject "SpaceNexus Research refund". Cancelling on My Desk on its own does not request a refund. After 30 days, cancelling stops the next renewal and you keep access to the end of the year you paid for. The full terms are on our Terms page.
No. Claiming a company profile, and every claim function, is free, forever. We never charge to claim, to verify or to correct a profile. Anyone can ask for a correction, with or without an account.
Card payments through Stripe. Wallets such as Apple Pay or Google Pay may appear at checkout where Stripe supports them for your device and country.
Most of what SpaceNexus shows starts as public data (NASA, NOAA, SEC EDGAR, USAspending, SAM.gov and 36 named sources in all), but collecting it, cleaning it, matching it to companies and keeping it current is continuous engineering work. SpaceNexus does that work and publishes the sources and methods behind it. The enthusiast core is free, and Professional is $19.99/month.
Two. Professional ($19.99/month) is for individuals who use SpaceNexus at work and adds alert rules, webhooks, full API access, an unlimited watchlist and no display ads. SpaceNexus Research ($399/year, 5 named seats) is the team plan: the paying account carries everything in Professional, and every seat adds the Research workspace: exports, saved screens, federal awards, SEC insider activity, Space Score history and the quarterly report. Teams that need something else can contact us.
Yes. SpaceNexus Research is the team plan: 5 named seats for $399 a year on one invoice. The paying account also carries everything in Professional.
We aggregate real-time data from NASA, NOAA, ESA, SpaceTrack, SEC filings, SAM.gov procurement and 60+ RSS feeds. Articles drafted with AI are labelled as AI-drafted.

Research is a strict superset of Professional: every Professional row above is repeated because the tier model repeats it, not because we say so, so the account that pays for Research does not need a Professional subscription as well. An invited seat unlocks the Research rows; /research explains the difference in full.
