Create, store, and share your datasets through AHED so that other researchers can easily discover, reuse and cite your data. We welcome a broad range of data types (e.g. field, laboratory, computational models, images), from the multiple disciplines in astrobiology.

There are two different options to make data accessible through an AHED dataset:
  • File Upload: Users can upload files directly from their computers, up to 20GB of data.
  • URL: Users can provide URLs, for example, other databases where their data is already publicly available, DOI’s of related manuscripts, project’s website, etc.
Before you begin, we recommend reviewing our Contribution Help-Guide

Five easy steps to contribute

(Hover over cards to read about the sections)


First time users without a NASA badge (NASA Smartcard or AUID), must create a NASA Guest Account to register in AHED. Approval will be dependent on the user’s established association with the astrobiology community, including their relationship to existing astrobiology-relevant projects, academic institutions, government laboratories, non-profit organizations, private foundation or industry. For NASA badge users NO registration is required. Directly log in with NASA launchpad credentials. See Instructions.


Only required to Contribute. Users can Sign in using NASA Launchpad with their NASA Smartcard or Agency ID and Password or using their NASA Guest Account credentials (after registration and approval). See Instructions.


A step-by-step wizard guides users in creating datasets.  Users will upload or link data and fill out associated metadata from the Astrobiology Resource Metadata Standard (ARMS).  


AHED data downloaded and used in publications should be acknowledged and referenced according to AHED’s Terms and Conditions.


Existing datasets can be edited by the creator at any time from  “My Datasets”.
