Inti is a solar-sail technology-demonstrator spacecraft built for the Aeronautics and Space Administration of Nouvelle Alexandrie (ASANA), the civil space agency of Nouvelle Alexandrie under the Department of Research and Development. Launched in 1759 AN from the Delgado Space Flight Center, the spacecraft deploys a reflective sail that produces thrust from sunlight alone, without carrying propellant. It is named for Inti, the Wechua sun deity.

The spacecraft was the first in ASANA's program to move beyond chemical launch toward propellantless propulsion. The mission is one of the earliest visible products of the federal diversification agenda that followed the Recession of 1757, the effort to shift the New Alexandrian economy away from its dependence on Alexandrium extraction and toward advanced science and manufacturing.

Background

The collapse of Alexandrium prices during the Recession of 1757 pushed the federal government to fund research that did not depend on the mineral, the diversification response to the long decline of Alexandrium. ASANA, whose launch vehicles and orbital operations had until then relied on conventional chemical rockets built by Javelin Industries, proposed a demonstrator that would prove a propulsion method requiring no fuel at all. A solar sail carries no propellant, which made it a fitting emblem for an agency asked to show that Nouvelle Alexandrie could build advanced systems rather than sell raw ore.

The mission took the name Inti, the Wechua sun deity, a choice that reflected both the sail's reliance on sunlight and the Wechua heritage of much of the federation's southern industrial base. It was the first ASANA spacecraft to carry a Wechua name, the agency's earlier craft having borne Martino and Alexandrian ones. Program managers described Inti as the space sector's contribution to a wider push, alongside the collider upgrade at Alduria, the advanced-materials work of Foundation 1768, and the photonics program Projet Prisme, to establish propellantless and high-technology capability as a national specialty independent of Alexandrium.

Development

ASANA authorized the Inti demonstrator in 1758 AN, drawing its funding from the advanced-sciences strand of the Aldurian Economic Diversification and Recovery Act, 1755 and a matching contribution from the Aldurian Development Corporation. The program budget was NAX€90 million, a small figure for a national space project, chosen deliberately to test a high-value technology at low cost. The appropriation followed the pattern set by the Frontera Program, the federal science-funding vehicle of 1738 AN, a precedent for several diversification-era projects.

Javelin Industries supplied the microsatellite bus and integrated the spacecraft, while ESB Thermodynamics produced the aluminized polymer sail film. The Nouvelle Alexandrie Aerospace Development Directorate provided the deployment-mechanism engineering, drawing on its experience with the Interstellar Research and Communication Array. The mission's principal investigator was Dr. Sayri Mamani, an ASANA propulsion engineer who had argued for a sail demonstrator since the mid-1750 ANs.

Qualification of the boom-deployment mechanism ran roughly seven months behind schedule after ground tests showed that the folded film could bind against its storage drum in vacuum. Engineers redesigned the drum liner and requalified the mechanism before flight. Opposition members later cited the delay during the 1759 general election campaign.

Spacecraft

Inti is built on a 12-unit microsatellite bus with a launch mass of 24 kilograms. Its sail measures 200 square meters, roughly 14 meters on a side, and is made of aluminized polymer film about two micrometers thick, folded around a central drum and pulled taut by four diagonal booms of coiled composite. Body-mounted photovoltaic panels power the avionics, and a small cold-gas reaction-control system detumbles the spacecraft before deployment and provides coarse pointing.

Four miniature cameras on the bus record the sail as it unfurls, both to confirm the deployment and to return imagery for the program's public-outreach work. The spacecraft carries no scientific payload beyond the instruments needed to measure the sail's performance: accelerometers, a sun sensor, and a set of strain gauges on the booms.

Mission

Inti launched from the Delgado Space Flight Center in 1759 AN as a secondary payload aboard a Javelin-built MSS CelestiaX, which placed it in a circular orbit near 1,000 kilometers, high enough that atmospheric drag would not overwhelm the faint push of sunlight. After a checkout period the spacecraft detumbled and began sail deployment.

The deployment did not proceed cleanly. One of the four booms extended only partway, leaving a quadrant of the sail creased and unopened. Controllers spun the spacecraft slowly about its long axis to draw the folded film outward by centrifugal force, and after several days the fourth quadrant reached full extension. With the sail deployed, ASANA measured a photon-pressure thrust of a few tens of micronewtons and used the sail's orientation to raise the orbit by a measurable margin over the following weeks, the first propellantless orbital maneuver by a New Alexandrian spacecraft.

Reception

The governing Federal Humanist Party presented Inti as proof that the diversification program could deliver, and the deployment imagery featured in party material during the 1759 general election. Opposition figures were less persuaded. Yuiza Bohi'o of the Wakara People's Party argued that a 24-kilogram demonstrator did little for constituents outside the industrial regions. Francisco Gabaza of the Federal Consensus Party questioned the cost against its return, and Marcos Ferreira Gonçalves of the Democratic Socialist Party pointed to the contractor share of the budget. Even within the government, Vice-Premier and Secretary of Defense Fred Strong, whose office managed the dual-use side of the diversification agenda, welcomed the result but cautioned that a single demonstrator proved a method rather than an industry, and that ASANA had a record of announcing ambitions ahead of demonstrated capability.

ASANA maintained that the demonstrator met its objectives and used the results to argue for a larger follow-on, a heliocentric sail provisionally named Killa for the Wechua moon deity, a deliberate pairing of sun and moon, which would carry the technique into interplanetary space.
