# Seven Puerto Rico research projects are headed to the space station — the aerospace pipeline grows without a launchpad

The Science Trust's $350,000 Space Edition grants drew sixteen proposals, four times its 2024 debut.

The Puerto Rico Science, Technology and Research Trust is sending seven local research projects to the International Space Station, each backed by a $50,000 grant — $350,000 in direct research funding, with launch costs covered on top of the awards[^1][^2][^3]. The program runs on funding from the island's Department of Economic Development and Commerce[^4], with commercial space biotech firm Rhodium Scientific preparing the projects for flight[^5].

Interest is scaling fast: the program's first edition in 2024 drew four proposals; this year's drew sixteen[^6][^7]. The 2026 slate runs from agriculture to biotech and materials science — plantain tissue adapted for space conditions[^8], Caribbean sargassum studied for oral-health applications[^9], materials manufactured in orbit[^10], and liquid-crystal sensors that detect substances without markers[^11]. One of the seven, Dr. Christopher A. Sambolín-Pérez's plantain project, asks how plant tissue responds to spaceflight[^12]. The pipeline has precedent: the Trust's first cohort produced Rhodium StemCell 01 — the first Trust-funded mission to reach space — launched aboard SpaceX's CRS-31 cargo mission in November 2024[^13][^14].

The grants ride a larger current. Invest Puerto Rico says the island's aerospace sector grew 62% over five years and added more than 8,200 jobs — a figure the agency does not source[^15][^16]. A May 2026 survey by Estudios Técnicos of 23 aerospace companies found firms planning workforce expansion over the next 12 to 36 months[^17][^18], but also island engineering and aviation salaries running 30% to 60% below California, Florida and Texas levels[^19]. Private money is moving too: Keystone Optical Network has committed up to $75 million to Laser Light Holdings and its planned HALO satellite constellation[^20].

What the island still does not have is a way to launch anything itself. The Local Redevelopment Authority's RFP for a vertical space launch facility at Roosevelt Roads in Ceiba — a site floated as a spaceport since 2023 — was cancelled, with the authority calling the move a best-public-interest decision[^21][^22][^23][^24].
