At ALMA, every observation depends on the precise work of the Logistics Department. Comprised of Claudia Johnson, ALMA Logistics Lead, and her colleague Ana Salinas, ALMA Logistics Assistant, both with more than 15 years at the Observatory, this team ensures the movement, distribution, and supply of the materials that enable science to continue.

Their work includes coordinating local and international shipments, managing the reception of cargo in Santiago and Antofagasta, processing documents with Customs and the Ministry of Foreign Affairs, and ensuring that every piece, from an electronic card to a complete antenna, arrives on time and in perfect condition to ALMA.

From the construction of ALMA to the current operational phase, they have been behind key milestones such as the arrival of the first antennas from Japan, the United States, Italy, and France. Their work requires coordination with warehouses, carriers, customs agents, and shippers, as well as careful planning to anticipate the needs of scientists and engineers.

“In a place like ALMA, where access is complex and time is of the essence, our commitment is to ensure that every piece of equipment arrives without a hitch. That way, we guarantee that science never stops,” says Claudia Johnson.

In a challenging environment, logistics is not just about moving materials: it’s about sustaining continuous operation, optimizing costs, anticipating solutions, and keeping running the machinery that allows ALMA to continue exploring the universe.

The impact of the team in figures

In 2024 alone, they managed 147 import operations (USD 10,348,337) and 91 export operations (USD 2,427,185). To sustain this movement, they coordinated 32 large trucks on the Santiago–OSF route and 41 smaller trucks in Santiago, other regions, and Antofagasta, moving a total volume of 372 m³ between imports, exports, and local purchases.

During Q1 and Q2 2025, they have carried out 110 import operations (USD 7,522,051) and 73 export operations (USD 2,847,591), using 19 large trucks and 27 smaller trucks, with a transported volume of 250 m³. These figures reflect the magnitude of the quiet but essential work that sustains ALMA daily.
