WHAT'S NEXT
​
The top 10 teams with the best Semifinal Round will advance to the National Finals event in Denver, CO. 
 
For the teams that do not qualify for the Semifinals Round or National Finals, we hope you learned something new about space operations and more importantly had a fun time competing. We encourage you to continue learning about space and aerospace engineering. As hopefully you can see, it’s a challenging and exciting field.
 
Good luck with the rest of your school year and have a wonderful summer. We hope to see you all again in the fall for the 2025-2026 StellarXplorers season! Registration for the new competition season will open May 1, so mark your calendars.

IMPORTANT REMINDER – DESTRUCTION OF STLX COMPETITION MATERIALS ​
All copies of the SFR competition scenario booklet, score sheets, STK VDFs, round emails, and team-produced documents must be collected and destroyed, or deleted, prior to March 7, 2025. 

ALL materials from previous rounds (PR1, QR1, PR2, QR2, PR3, and QR3) MUST have been destroyed by now.​

PROCEDURAL OBSERVATIONS
​​Team Numbers
Your team number (STLX11-XXXX) is very important during the StellarXplorers competition. It is how we track your results, store your files, and most importantly grade your solution.

Our automated grading system looks for your team number in order to launch the scoring process. It looks for precisely 11 characters (STLX11-XXXX) to find and score your file. If there are more than or less than these 11 characters, the grader will abort the scoring process for all teams, and we must manually repair the incorrect team number. For example, say your team number is STLX11-0987.  Typing anything other than STLX11-0987 will cause the grader to abort.
 
To help you avoid this mistake in the future, view the newly created “Penalty Paper” to see a list of all the wrong ways (and the only right way) to provide your team number. This document also outlines other common penalties and how to avoid them. If you need clarification, contact [email protected].
Moving forward, teams will be penalized 5 POINTS each time they submit something with an incorrect team number. This includes the start form, academic quiz, solution upload/submission form, and/or VDF filename. It is imperative that you provide the correct team number in the correct STLX11-XXXX format.
 
And as always, include your team number in the subject line of all messages to us. It makes it easier for us to find you in our database and to file the information that you send to us.
 
Running Systems Tool Kit (STK)
As emphasized in prior communications, teams should load STK 12.5 Pro with the Planetary Data Supplement onto their computers and test that the software is operating successfully BEFORE STARTING THE ROUND. By “before” we mean days before, and also immediately prior to starting. We cannot guarantee staff support for last-minute technical issues, and teams will not be given any time relief if they do not have STK running on their computers at the start of the competition period. If needed, sample VDFs are available with our Training Materials, and can be used to test the software.
 
For those still needing licenses, please reach out to the StellarXplorers Program Staff as soon as possible to request them.

Incomplete Submissions
Be sure you hit SUBMIT once you've made your selections. You'll know your selections have been submitted, when you receive the automated emailing confirming the team's selections. There's no automated email notification for the VDF upload, but you will receive a confirmation message on the screen once the process is completed.
  
​Space Foundations Course (Nova Space)
Please make sure your team has access to the Nova Space learning platform BEFORE starting the round. Utilization of this course is instrumental in preparing for the academic quiz. If you need help accessing the course, please contact the StellarXplorers Program Office.
 
Confirmation Emails
Team directors will receive automated confirmation emails upon submission of a team’s start form, scenario component selections (in rounds 2 and 3), and academic quiz (when applicable). Currently, we are unable to provide automated confirmation emails for receipt of VDF submissions, but you will receive a confirmation message on the screen once the process is completed.
 
Confirmation emails are sent to the email address provided in the “Team Director Email” field of the forms. To ensure there’s no delay in the delivery of these automated emails, competitors should pay close attention to the email address they are providing. There were significantly fewer instances of incorrect email addresses this round.
