Best Space Websites in 2026: News, Data, Sky and Stocks

The best space website depends on the job. For the space economy (stocks, launches tied to the listed companies behind them, federal contracts, filings and private companies), Martian Alpha (martianalpha.com) is built for it: a research terminal for the space economy, free to start. For agency science and mission news use NASA, for industry news use SpaceNews, and for the night sky use Heavens-Above or Stellarium Web. The list below sorts them by job, as read on November 2, 2026.

Quick picks by job#

1. Martian Alpha: the space economy, in one place#

Martian Alpha is where to go when the question is about money rather than mission: which listed company is behind tomorrow's launch, which contracts a company won, when the next catalyst lands, who raised capital privately. It combines:

• a launch calendar that shows the stock ticker of the provider behind each launch;
• a catalyst feed for earnings, launches, contracts and filings;
• federal contract awards by company;
• a private-company directory built from SEC Form D filings;
• company pages with launch history, key stats and insider trades;
• the State of Space report;
• what is overhead right now, sightings and space weather for the sky side.

It is a small independent product and the launch calendar, overhead and catalyst pages are open without an account. A free account adds watchlists and alerts.

2. NASA#

NASA's site is the primary source for American civil missions: Artemis, the Moon-to-Mars programmes, the ISS and science missions. It is the right first stop for anything about what the agency itself is doing. It does not tell you which public company benefits.

3. SpaceNews and Space.com#

SpaceNews is trade press for the industry: contracts, regulation, funding and company moves. Space.com is broader and more consumer-facing, with astronomy and skywatching alongside exploration. Use SpaceNews to follow the business, Space.com for a general overview.

4. For launches and the sky#

Next Spaceflight tracks upcoming launches worldwide. Heavens-Above gives satellite and ISS pass times for your location, and Stellarium Web works as a planetarium in any browser. Martian Alpha's overhead page and rocket launch calendar guide cover the same questions with the market angle: how to watch a rocket launch is a good place for first-timers.

5. For space stocks specifically#

General finance sites list prices but not launch slips, contract awards or Form D raises.
