Hubble Space Telescope Call for Proposals for Cycle 22 > Chapter 7: Guidelines and Checklist for Phase I Proposal Preparation > 7.1 General Guidelines

7.1 General Guidelines
7.1.1 Deadline
Please submit well before the deadline whenever possible, to avoid possible last-minute hardware or overloading problems, or network delays/outages. Late proposals will not be considered.
 
Questions about policies and technical issues should be addressed to the STScI Help Desk (see Section 1.5) well before the deadline. While we attempt to answer all questions as rapidly as possible, we cannot guarantee a speedy response in the last week before the deadline.
7.1.2 Phase I Proposal Format
Cycle 22 Proposals must be submitted electronically. A Java-based software tool, APT (the Astronomer’s Proposal Tool; see Section 1.4.5) is the interface for all Phase I and Phase II proposal submissions for HST.
A Phase I proposal consists of two parts:
Both are submitted to STScI directly from within APT. Student Principal Investigators should also arrange for a certification letter to be sent by their faculty advisor (see Section 2.3.3).
Please study Chapter 7, Chapter 8, and Chapter 9 carefully. We recommend doing so well before the submission deadline, to give the STScI Help Desk (see Section 1.5) ample time to answer any questions you may have.
7.1.3 Page Limits for PDF Attachment
There are page limits on the size of your PDF attachment. Table 7.1 outlines these limits for different proposal categories.
