All NASA mission directorates are currently gathering requests for High-End Computing Capability time on resources at the NASA Advanced Supercomputing (NAS) facility for awards to begin October 1, 2025. The deadline for submitting requests is July 20, 2025.

• Aeronautics Research Mission Directorate (ARMD)
• Exploration Systems Development Mission Directorate (ESDMD)
• NASA Engineering and Safety Center (NESC)
• Science Mission Directorate (SMD)
• Space Operations Mission Directorate (SOMD)
• Space Technology Mission Directorate (STMD)

ARMD, ESDMD, NESC, SMD, SOMD, and STMD managers will consider eligible requests submitted via the HEC Request Management System (RMS) to the rolling submission calls by the July 20, 2025 deadline.

For work supported by NASA outside of ARMD, ESDMD, NESC, STMD, SOMD, and SMD, you may renew your project(s) and apply for time under the MISC (miscellaneous) category. The MISC category does not have a share of HECC resources, so requests will be evaluated on a case-by-case basis with no guarantee of an award of computer time.

For Continuing Projects

1. Log into the Request Management System.
2. Confirm your project’s Period of Performance end date is correct. If not, click on Request New End Date. Unused FY25 allocations will not be rolled over. Remember to request more resources for the new fiscal year, after completing the extension form.
3. Review your requested resources for FY26 and any future years). If you need to adjust your requested resources, click on the Request More Resources link, and complete the form. You can enter a negative number to decrease your request.
4. If your project’s end date and requested resources for FY26 are correct, no action is required.

Note: You should only submit a new request if significant changes to the project are required. For minor updates, such as a new WBS or change to funding manager, please contact support@hec.nas.nasa.gov. Projects that do not have an FY26 allocation will be disabled.

For New Projects

For new projects, please submit a request if:

• You are responding to a Research and Opportunities in Space and Earth Sciences (ROSES) solicitation (SMD reviews eligible requests quarterly).
• You have NASA funding for a new project you want to begin October 1, 2025.

To submit your request, go to the Request Management System.
