Plenary sessions are 30 minutes long; no other sessions or events are scheduled in parallel with them. Plenary talks will be prerecorded and there will be Live Q&A Sessions as well as Slack Chat available. Plenary speakers will receive special abstract and presentation instructions from the AAS Executive Office.

Regular oral presentations, as well as dissertation oral presentations, are generally arranged by topic. For a regular oral presentation, allow 7 minutes for the prerecorded talk. For a dissertation oral presentation, allow 12 minutes for the prerecorded talk. Please note that captioning will be added to all live and pre-recorded oral presentations. In order to process the videos, all recordings will be due 9 September. 

Regular, history, and education iPosters allow far more time and flexibility than the corresponding oral presentations. iPosters are arranged by topic and are created online using easy-to-use, web-based templates. Your iPoster will be displayed in the iPoster Gallery and will be downloadable to smartphones, tablets, and desktop computers during the meeting and for at least one year after it concludes. You can add as much text, media content and recorded narration as you need to present your research with all the detail it deserves. iPoster presenters will be scheduled in a session and there will also be Slack Chat available for additional discussions. While iPosters must be “published” by 9 September in order to be included in the Gathertown session, the contents can be edited until the beginning of the meeting. 

Types of Discussion Sessions 

All presenters are expected to participate in asynchronous discussion via slack.  

Live Q&A 

Live sessions (e.g. on zoom) will require presenters to prepare a summary slide ahead of time and give a lightning talk at the beginning of the session, then will participate in a live question and answer session moderated by the session chair.  

Gathertown 

Participating in Gathertown will require presenters to make a poster, even if their primary presentation mode is a pre-recorded oral talk. There will be dedicated time to browse the Gathertown halls.  

Note presenters can choose any combination of discussion formats (slack/live/Gathertown), regardless of presentation format (oral/iPoster). 

• Slack + Live + Gathertown 
• Slack + Live 
• Slack + Gathertown 
• Slack only 

Abstracts must be submitted through the presenting author's AAS record. Co-authors are not eligible to substitute as the presenting author. The presenting author will be notified once the schedule has been determined. 

Abstract Login Instructions 

To submit an abstract, you must first log into the system using your AAS Login. 

• If you are a member of the AAS you should already have a login.  
• If you are not a member of the AAS you may create an AAS Login if you do not already have one. 

Abstract Form Details 

The form contains instructions on the various steps required to complete a submission. 

• The abstract must be complete and submitted by the deadline, 11:59 pm EDT, 22 July 2021. 
• The abstract body text can be a maximum of 2,250 characters (which includes letters, numbers, punctuation, and symbols/special characters). 
• To enter co-authors, you must have the following: full first and last name, e-mail address, and affiliation. 
• You can continue to make changes to your abstract before the deadline. To edit an abstract, sign back in and find the abstract you submitted and make changes. Please remember to resubmit once you have made changes. 

To switch the presenting author to a co-author you must submit a new abstract by logging in as the new presenting author. 

Categories are used as a guide for the Scientific Organizing Committee to build coherent sessions. The final session assignments and session titles are at the discretion of the Committee.

(2) History Contributed Presentations

(3) Education and Community Engagement Contributed Presentations

(4) Workforce Contributed Presentations 

To encourage the sharing of work highly relevant to the planetary science community, but generated by professionals outside of the planetary science community (e.g., social science results relevant to DPS workforce, education/community engagement, or history discussions): a limited number of discounted DPS 2021 meeting registrations are available and can be inquired about via the DPS Professional Climate and Culture Subcommittee: [email protected]. These discounted registrations are intended for persons who submit an abstract to DPS and engage in the meeting, and whose work would benefit the planetary science community, but who in general receive little professional benefit from attending the meeting (and so generally would not attend).

iPoster Presentations 

iPoster Session Tutorials 

Guidelines 

With the iPoster system, you will be able to create an interactive presentation that includes high-resolution images, high-definition videos, narration, interviews, viewer surveys, and more. 

• iPosters are created online using easy-to-use, web-based templates. 
• Your iPoster will be displayed in the iPoster Gallery and will be downloadable to smartphones, tablets, and desktop computers during the meeting and for at least six months after the meeting concludes. 
• All presentations are required to be available for thirty (30) days, if you would like to remove your content after that please contact us for assistance. 
• You can add as much text, media content and narration as you need to present your research with all the detail it deserves. 
• iPoster presenters will be scheduled in a session and are encouraged to participate in scheduled Slack Chats. 

Tips 

• Viewers can reach out to you via the "Contact Author" button at the bottom of your poster. 
• Include narration so attendees can listen to your presentation (while they scroll through your iPoster) even when you're not there. 
• After your abstract is scheduled, you will receive a username and password to login and author your iPoster

Oral Presentations  

Prerecording Your Presentation 

Guidelines 

• All oral presentations will be prerecorded. Training and additional instructions about uploading talks will be provided. 
• Seven (7) minutes are allowed for the normal oral presentation and live discussions and Q&A will be scheduled via Slack Chats. 
• When preparing your presentation, we suggest a maximum of three slides for a seven-minute talk. Slides should be uncluttered and easy to read. 
• Presenters are encouraged to practice a few times so the presentation fits comfortably into the seven-minute slot. 

Dissertation Presentations 

If you would like to present a dissertation abstract or want recognition, please be sure to select the options when submitting your abstract under the "Additional" information section. Dissertation recognition can be given for orals or iPosters. 

• Twelve minutes are allowed for the dissertation oral presentation. Oral presentations will be prerecorded. Q&A will be scheduled via Slack Chats, and authors will have a choice to participate in live discussions via zoom and/or host a poster in Gathertown, same as for regular oral presentations. 
• iPosters will also have Q&A scheduled via Slack Chats, and authors will have a choice to participate in live discussions via zoom and/or host a poster in Gathertown, same as for regular iPosters presentations. 
• Abstracts and presentations should be based upon the author’s dissertation material and will be presented within regular sessions of appropriate topics. 
• Only students or graduates within one year of having a PhD conferred by their university or college are eligible. These abstracts are subject to the same rules of preparation and submission as regular abstracts, but they will be specially marked with a “D” in the program materials. For oral presentations, the author may request 12 minutes instead of the standard 7 minutes.

• Online Program of Abstracts — Available during the meeting; includes full abstract text. 
• Astrophysics Data System (ADS) — Abstracts are sent to ADS and typically published shortly before the meeting. 

Edits to Abstracts 

• If you have a problem with the scheduling of your presentation, please email the abstract help desk. We will try to accommodate your request if possible. 
• We understand that edits sometimes need to be made to abstracts after they are submitted. We try hard to accommodate edits and changes as we lead up to the conference, but due to certain deadlines we will be unable to edit abstracts within two weeks of the meeting start date/.
