COSMOS 7 is Officially LIVE with a NEW Time Series Database!

COSMOS 7 is finally HERE! The newest, fastest, most scalable version of aerospace’s preferred orchestration platform is now available for Core and Enterprise customers.

 

COSMOS 7 is a huge leap forward in functionality and extensibility, making COSMOS an order of magnitude faster at data retrieval,easier to use with even more Python support, and more flexible with new workflow support.  

 

 

What’s New With COSMOS 7?

COSMOS 7 is more than a routine update, COSMOS 7 enables developers, engineers, businesses, and organizations to leverage COSMOS for mission success in ways never before possible. Here are some of the revolutionary features jam packed into COSMOS 7:

 

NEW Time Series Database

COSMOS 7 data retrieval has now gotten faster by an order of magnitude, eliminating processed bin files through use of our time series database, QuestDB. COSMOS will now ingest all the existing processed bin files into QuestDB with throttling and move the bin files or mark them as processed. Raw bin files will remain as backup in MINIO.This enables optimizations like the removal of the reducer microservices and associated data, opening the door to a host of new integrations and use-cases including data exploration with SQL!

 

COSMOS Notebooks

Now COSMOS is open to an universe of new possibilities. COSMOS Notebooks is more than an interactive procedure tool. Notebooks is a blank canvas, primed for blocks of Markdown text, checkboxes, executable Script Runner blocks, embedded telemetry screens,and more, providing a structured way to guide operators through complex procedures while maintaining a complete audit trail of execution.

 

Even Greater Python Support

Python continues to be the go-to choice for COSMOSnauts the world over. Now COSMOS is even more Python-friendly thanks to the addition of a protocols for porting GEMS, gRPC interface and SNMP interface to Python.

 

Cleaner API

Several deprecated API methods have been removed from the COSMOS API, making COSMOS lighter and faster.

 

Prettier UI

COSMOS 7 now offers the ability to update and change theme colors for a more branded look and feel.

 

 

Freer COSMOS

For many prospective COSMOS users, AGPL can be a dealbreaker, even when creating plugins for Enterprise COSMOS. COSMOS 7 comes with an updated license, opening the door for COSMOS users to build their own plugins, free of AGPL licensing restrictions. COSMOS Enterprise is now licensed under the OpenC3 Builder's License (https://github.com/OpenC3/cosmos/blob/main/LICENSE.md),which comes with all of the freedoms of the AGPL license but restricts the use of COSMOS as a service and removes the need to account for virality when extending COSMOS. COSMOS Core remains open source and also adheres to theOpenC3 Builders License.

 

 

Get Started with COSMOS 7

To get started with COSMOS 7, please head to GitHub and download the latest build here:

Critical Update Note

If you are updating from a 7.0.0 Release Candidate, a full TSDB cleanup is required as table names now include the SCOPE.

  • Action: Run openc3.sh cleanup (Note: This drops all logged data!!!)
  • Alternative: Manually delete the volume via dockervolume rm xxx-tsdb-v

 

 A huge “thank you” from the dedicated development team atOpenC3 to all COSMOSnauts for helping make COSMOS 7 the best COSMOS ever and for helping usher in a new dawn of COSMOS success!
