Planetary and Space Sciences PhD Program

This page describes many of the details about the Planetary and Space Sciences PhD Program within the Department of Physics.

Note that the Planetary and Space Sciences PhD Program is a different entity from our Planetary Sciences Track within the Physics MS and PhD program. Both the MS and PhD options of this Track are still active, although we will soon no longer be accepting applications for the Track. Applicants wishing to begin studying planetary science and space science at UCF in Fall 2026 or later should apply to the Planetary and Space Sciences PhD Program and not the Track.

Our PhD Program emphasizes research from the first semester, since writing a paper and submitting it to a journal is a candidacy requirement, and one can only formally start dissertation research once one has been admitted to candidacy (a.k.a. “ABD”).

The best way to learn about our PhD program is to read:

Applying to the Program

For information on general UCF graduate admissions requirements that apply to all prospective students, please visit the Admissions and Registration section of the Graduate Catalog. Applicants must apply online.

Information about admission to the Planetary and Spaces Sciences PhD program itself can be found in (as mentioned above) in the program handbook, the Graduate Catalog, and the departmental website (in particular the admissions page).

If you are an International Applicant and want to ask about either (a) getting a waiver for the application and/or the WES/Josef Silny transcript evaluation, or (b) having us assess whether your application would be competitive for our typical applicant pool: Please contact us — planets@ucf.edu — by June 1st for a Spring Admission or by November 1st for a Fall Admission. You must send us (i) your CV, (ii) an unofficial transcript, (iii) your application essay, and (iv) a clear indication of which 1 to 3 faculty with whom you are interested in working. (If you are concerned about information on your transcript being sent insecurely by email then you can provide us with a link to e.g. Dropbox, Google drive, etc. instead.)

All requested materials must be submitted by the established deadline(s). There is a page with UCF’s application requirements. Requirements for our program in particular are in the Graduate Catalog. Note that we no longer require a GRE score. Our admissions committee recognizes the limitations in the ability of the GRE test to predict success in graduate school. (Background info about this topic is here and here.)

Note that the statement of goals/essay/personal statement is particularly important. In particular:

Applicants should identify one or more projects/areas they would be interested in pursuing as a potential dissertation topic.
- This should include discussion of their specific project interests in their applications.
- (Note that students can change projects once in the program, provided that another project/mentor is available.)
Applicants should identify specific faculty with whom they are interested in working.
- Note that the global planetary-science community maintains a list of faculty looking for new students.
- If your favorite UCF scientist is not on that list, that’s OK! We still want you to apply. But in that case it very much helps to have contacted beforehand the faculty you’re interested in. We highly recommend attempting to have a conversation with potential research mentors.
- Keep in mind that Physics Department graduate students can have UCF faculty in other units as their research advisor. Several of our students work with faculty in FSI and CREOL.
Applicants should check out the advice and suggestions for the application essay found on our Jobs page.
- We need detail about an applicant’s research experiences to fully evaluate your application.
- We will want to know: what did YOU do, what problems did you face, and how did you handle them?
Applicants that get accepted generally have research experience in planetary science, geophysics, geology, astronomy, or astrophysics.
- If your research experience is outside these areas, then it is even more important to discuss in your essay how you fit into our program.

Note that students must be specifically admitted to the Planetary and Space Sciences PhD program. External or internal applications and petitions to switch from the existing Physics graduate program (including the Planetary Sciences Track within the Physics program) are considered by the Planetary Graduate Committee. Please contact us first if you are thinking about switching.

Admission to the program requires a Bachelor of Science or equivalent, typically in physics, astronomy, geology, geophysics, geochemistry, atmospheric sciences, biology, mathematics, or planetary sciences. Those without full academic preparation in relevant natural sciences may be required to complete specified coursework in addition to the core program, as determined by the Planetary Graduate Committee at the time of admission or their Supervisory Committee at a later date.

Note that just meeting minimum UCF admissions criteria does not guarantee admission to the program. We generally have far more high-quality applicants than we have room for! Admission is based on the applicant’s abilities, past performance, recommendations, match of this program and our faculty’s expertise to the applicant’s career/academic goals, the applicant’s potential for completing the degree, available positions, and other factors.

The application deadlines are as follows:

Admission semester:	Fall Priority	Fall	Spring
Domestic applications	December 1	July 1	December 1
International applications	December 1	December 1	July 1

If you are applying for Fall Admission: We prefer to receive complete applications by December 1, so please do not wait until July 1 (domestic) to complete your application. We of course look at all applications that are submitted by the deadline, but even a great application may be rejected if it is submitted so late in the process that we simply do not have any more open slots for new students.

If you are applying for Spring Admission: Please contact us ahead of time to see if it is worth it to apply. For academic, logistical, and financial reasons, we usually do not admit many students to start in the Spring, so in many cases it is just more sensible for you to apply for Fall Admission instead. Please get into contact with the faculty here with whom you are interested in working, and ask them if they are planning on adding students in the Spring semester. If they are not, then it is unlikely that you’d be admitted. Alternately, send email to our general address — planets@ucf.edu — with any questions or concerns you have about Spring Admission.

For Fall Admission: applications received by December 1 will receive full consideration for funding, and fellowships are unlikely for applications received after this date. We evaluate applications in December, January, February, and March each year and make most admissions decisions and funding commitments (GRAs and GTAs) then. Officially, we can admit as late as July (domestic) for Fall enrollment, and we can admit for Spring enrollment, but such cases are atypical. Since July 1 is UCF’s official cutoff for Fall, that is listed as the application deadline, but those seeking financial support should apply by December 1.

Graduate students may receive financial assistance through fellowships, assistantships, tuition support, or loans. For more information, see Financing Grad School, which describes the types of financial assistance available at UCF and provides general guidance in planning your graduate finances. The Financial Information section of the Graduate Catalog is another key resource.

Note that UCF does have a policy regarding parental leave for GTAs and GRAs; paid leave is provided for up to six weeks.

Example Course Sequences for Graduate Students

Here are some example course sequences. Full-time, pre-candidacy students must take 9 credits in Fall, 9 credits in Spring, and 6 credits in Summer. PhD candidates must take at least 3 credits in each of Fall, Spring, and Summer (typically these are Dissertation credits), and may register for more, such as electives, with advisor approval. Note that some GRAs and Fellowships do not cover more than the minimum tuition.

In the parlance of UCF, 9 credits of courses — even if some of those credits are research credit — is considered a half load and ostensibly this takes up 20 hours per week of a 40-hour work week. The other half, the other 20 hours of a work week, is typically taken up by the job you are paid for: i.e., a Graduate Teaching Assistant (GTA) or Graduate Research Assistant (GRA). As a “full-time” GTA, you are paid for 20 hours per week as a teaching assistant. As a “full-time” GRA, you are paid for 20 hours per week on research.

The research that you do in your first two years is supposed to be the research that leads to a submitted manuscript in time for your candidacy exam. See the Graduate Program Handbook for discussion of the candidacy paper’s presentation and the oral defense.

Students entering in the program in Fall 2026:

Fall 2026	Spring 2027	Summer 2027	Fall 2027	Spring 2028	Summer 2028
PHY 6246 (3cr) Classical Mech.	AST 6112 (3cr) Origins	Research (6cr)	AST 5145 (3cr) ACM	AST 6165 (3cr) Atmo.	Research (6cr)
AST 5151 (3cr) PPP	AST 5154 (3cr) Geophys.	…	Research or elective (3cr)	AST 5263 (3cr) Obsv.	…
AST 5765 (3cr) Data	Research or elective (3cr)	…	Research or elective (3cr)	Research or elective (3cr)	…

“Research” in the above table refers to usually AST 6918, directed independent research. That research work can be aligned with the research you would already be doing anyway for your candidacy-exam project.

By the end of your second year (i.e. end of 6th semester) you should have accumulated 48 credits. This will include all 18 required credits for core courses, and 30 out of the 39 required credits from electives. Generally this means that students take the remaining 9 credits of electives during their third year. Depending on your supervisory committee and on current College of Graduate Studies rules, you may be able to take your candidacy exam during the summer of your second year or the fall of your third year. Ideally, the candidacy exam should be taken no later than the spring of your third year.
