Research Opportunities
Astrophysics research usually begins with writing a proposal. A proposal is a document that is submitted in response to a specific solicitation. This table shows the most common solicitations relevant to NASA astrophysics. Solicitations are released to the public on a specific date, called the Release Date, which is usually about the same day each year for a given solicitation. Some solicitations require submitting a Notice of Intent (NOI). This is a short document declaring your intention to submit a proposal at a later date. If one is required by the solicitation, the deadline is shown in column NOI. Proposals must be submitted by the deadline, called the Submission Date, or they will generally not be accepted. Proposal writing takes time (e.g., three months or more for a first-time proposer). Use the submission date to plan in advance. Hyperlinks on the proposal name will take you to the solicitation. Before you begin writing a proposal, read the solicitation to determine whether you are an eligible proposer, whether your science interests broadly align with the goals of the solicitation, and what will be required to write the full proposal. Good luck!
