LPI Summer Internship in Planetary Science: 2026 Historical Reference

LPI Summer Internship in Planetary Science: 2026 Historical Reference

The 2026 LPI Summer Intern Program in Planetary Science was a 10-week undergraduate research program run by the Lunar and Planetary Institute (LPI), an institute operated by the Universities Space Research Association. Students worked with scientists at LPI or NASA’s Johnson Space Center in Houston, Texas. This page is now a historical reference: the official LPI application page says that applications for Summer 2026 closed on December 12, 2025, and the official LPI pages do not publish an application window for the next cycle.

Do not treat this page as an open application. The official program site remains the right place to watch for a future round, but there is no current deadline here for a later cohort. The closed 2026 date stays in the metadata because it is the real deadline for the cycle described below.

2026 program at a glance

The financial support should not be read as a separate cash award on top of every expense. LPI says that selected interns receive at least $13,351 in support for their stay in Houston. The amount covers the internship stipend, travel, housing, and cost-of-living expenses. Housing is paid directly to the housing vendor from that total and is deducted from the total stipend amount. The official support page does not list an additional payment beyond this support, so the older extra-payment claim has been removed from this historical listing.

What the 2026 opportunity offered

The program was designed for undergraduate students who wanted supervised research experience in lunar and planetary science. During the 10-week placement, each intern worked one-on-one with a scientist from LPI or NASA Johnson Space Center on a research project. The program also included lectures, career-development activities, planetary science seminars, and visits connected with NASA Johnson Space Center facilities.

The research setting was broad rather than limited to one mission or one technical method. LPI’s program materials describe work connected with planetary science and related areas such as planetary geology and surface processes, impact cratering, remote sensing and spectroscopy, geochemistry, petrology and mineralogy, planetary interiors and geophysics, lunar science and exploration, asteroids and other small bodies, interplanetary dust and presolar grains, meteorites and sample analysis, astrobiology, planetary atmospheres, and icy satellites. The exact project depended on the mentors and projects available for that cohort.

The program was held in person in Houston for participating interns. LPI and NASA Johnson Space Center are near one another, but an applicant should not assume that every project has identical day-to-day arrangements. The FAQ says interns were housed at University Forest Apartments and that access to a car was recommended in most cases. If a selected intern’s project required travel to an off-site location, the intern was responsible for providing transportation.

Eligibility for the closed 2026 cycle

The official eligibility page states that applicants needed to be undergraduates who had completed at least 50 semester hours of credit. Students majoring in physical or natural sciences, engineering, computer science, or mathematics were preferred, but LPI said that all eligible students would be considered. Selection was based on scholarship, curriculum and experience, career objectives and scientific interest, and the match between the applicant’s interests and available research projects.

The opportunity was open to U.S. citizens and foreign nationals, with an important restriction: citizens of countries on the U.S. State Department Designated Countries list were not eligible because of security requirements. International applicants therefore needed to check the official eligibility information and the linked export-control guidance rather than assume that “international” meant every nationality was accepted.

The FAQ adds context for students who already hold a bachelor’s degree. LPI could consider a degree conferred in the fall or spring semester preceding the summer program, but the main focus was students actively pursuing a bachelor’s degree and enrolled in a college or university during the semester before the internship. Someone pursuing a second, relevant bachelor’s degree could still be eligible under the conditions described by LPI.

Foreign nationals whose primary language was not English needed current proof of English proficiency. LPI accepted a TOEFL score, an IELTS score, or a letter from a professor in the applicant’s college English department confirming sufficient spoken and written English skills for successful participation. The application materials themselves had to be submitted in English, and the FAQ says transcripts in another language had to be translated into English by the applicant’s institution.

Application requirements and process

The 2026 application was online only. Paper applications were not accepted. LPI instructed applicants to complete every question in the online form, including the essay-style questions, and to submit all materials in English. After submission, the applicant received a confirmation email with an application number and a link for tracking recommendation letters.

The required materials were:

• The completed online application, including the essay-style questions.
• At least two letters of recommendation, with a maximum of three, submitted through the online application system.
• An official transcript. LPI accepted an official original transcript by mail or an official electronic transcript sent directly by the institution’s registrar or transcript service.
• Current English-proficiency evidence for foreign nationals whose primary language was not English, using one of the three options listed above.

Recommendation letters could not be replaced by emailed or mailed letters. Each recommender received a unique link and submitted the recommendation electronically through the application system. LPI preferred recommendations from faculty at the applicant’s current institution, but the FAQ also lists teaching assistants, academic advisers, faculty from a previous institution, employers, and supervisors as possible recommenders when they could speak meaningfully about the applicant’s qualifications, character, relevant experience, or academic potential. LPI staff and current Johnson Space Center mentors were not appropriate recommenders.

Applicants did not need to identify a potential mentor before applying. They could submit the application before all recommendations arrived, but the recommendations still had to be completed through the system for the application to be considered. Official electronic transcripts had to be sent directly by the institution or its transcript vendor to the email address listed on LPI’s application page, with the application number included in the delivery details. A mailed original transcript was sent to the LPI Summer Intern Program at 3600 Bay Area Boulevard, Houston, Texas 77058-1113, with the application number when available.

2026 timeline

The official LPI dates page lists December 12, 2025 as the application deadline. The eligibility page specifies 11:59 p.m. U.S. Central Standard Time and says incomplete or late applications would not be considered. LPI expected to notify applicants of selections in March 2026, and selected students had two days to respond to an offer.

The program began on June 1, 2026 and ended on August 7, 2026. The official schedule lists the LPI Summer Intern Conference on August 5, 2026, followed by departure on August 8, 2026. Interns were expected to be present for the complete program and could not miss orientation on the first day. The FAQ says the core working hours were Monday through Friday, 9:00 a.m. to 5:00 p.m., with short absences considered only for limited valid reasons such as illness or binding personal and academic commitments.

What applicants could prepare before the deadline

For the closed cycle, the strongest preparation would have been practical and evidence-based. An applicant could first confirm that at least 50 semester hours would be complete, that the student status requirement would be met, and that nationality and security restrictions did not create an eligibility problem. Next, the applicant could review the research areas and identify two or three specific interests, such as spectral analysis, planetary geology, sample science, or computational work with planetary data.

The essay responses should have connected those interests to actual preparation. A useful answer would name relevant courses, laboratory work, coding, data analysis, field experience, technical writing, or a research project and explain what the applicant learned from it. General enthusiasm for space was not enough on its own. The selection criteria made the connection between academic experience, scientific interests, and available projects important.

Reference writers needed enough time to submit through the online system. A concise packet containing a résumé, transcript, project notes, the program description, and a draft of the applicant’s research interests could help a recommender write a specific letter. Transcripts and English-proficiency evidence also deserved early attention because the transcript had to be official and recommendations could not be sent by ordinary email.

Applicants should have checked the application confirmation and recommendation status after submitting. They should also have kept copies of their essays and verified that the registrar or transcript service used the application number. These steps would not replace the official instructions, but they would reduce avoidable administrative problems near the deadline.

Historical status and where to check next

LPI announced the 2026 class in April 2026, confirming that the selection stage had occurred. The 2026 program dates and the closed application statement remain useful for applicants comparing past rounds, planning future coursework, or understanding the scale of the support. They are not an invitation to submit an application now.

No deadline or application form for the next cycle was announced on the official LPI program, eligibility, dates, application, support, FAQ, or internship overview pages reviewed for this update. Because a future cycle has not been published, this page does not invent a replacement date. Anyone interested in a later round should use the official LPI program page below and confirm the new eligibility, funding, dates, and application instructions when LPI posts them.
