Programa Wichay (Wechua for "the ascent") is a proposed space-access research and development program of the Federation of Nouvelle Alexandrie, chartered in 1759 AN to study whether a momentum-exchange tether could lower the cost of reaching orbit. Such a tether, a long rotating cable held in orbit by a heavier counterweight and often called a skyhook, would catch a suborbital vehicle at the bottom of its swing and release it higher and faster, transferring part of the tether's own momentum to the payload. The program is led by the Aeronautics and Space Administration of Nouvelle Alexandrie (ASANA), the civil space agency of the Department of Research and Development, with the Nouvelle Alexandrie Aerospace Development Directorate as its technical agent and Javelin Industries as principal contractor.
Programa Wichay is a feasibility and technology-development framework rather than an approved flight system. Its 1759 AN charter authorizes a three-year study and a program of materials, rendezvous, and reboost research; it commits no vehicle to orbit and claims no launch capability ahead of a demonstrated capture. The program belongs to the wider diversification agenda that followed the Recession of 1757, the same push behind the solar-sail demonstrator Inti (spacecraft) and the nuclear program Project Kallpa. It draws its funding from the advanced-sciences strand of the Aldurian Economic Diversification and Recovery Act, 1755, with a matching contribution from the Aldurian Development Corporation. Wichay is the newest of the Federation's Wechua-named technology programs, joining Programa Cóndor in aeronautics and Programa Ayar in land systems.
Background
The Federation entered the 1750 ANs dependent on a single export, Alexandrium, and on a launch sector that flew almost entirely on chemical rockets built by Javelin Industries for ASANA. Published by the Institute for Strategic Studies, the 1751 AN report The Alexandrium Horizon warned that the mineral's output would reach its peak within a generation, and the 1757 Alexandrium market crash during the Recession of 1757 turned that warning into policy. The government of the Federal Humanist Party answered with a diversification agenda meant to prove that Nouvelle Alexandrie could build advanced systems rather than sell raw ore, and space access became one of its priorities.
Two limits shaped the space side of that agenda. The cost of every kilogram sent to orbit remained set by the propellant a rocket had to carry to reach orbital speed, and ASANA had long lagged in mission cadence, concentrating instead on new technologies. Inti answered the first limit for one small spacecraft by moving beyond propellant altogether, raising its orbit on sunlight in 1759 AN. Programa Wichay was chartered to ask whether the same principle, letting an external system rather than an onboard tank do the work of acceleration, could be applied to launch itself.
The program carries a material tension. The only material the Federation can manufacture with the strength to build such a tether is an Alexandrium-reinforced composite, so a program conceived to move the economy off Alexandrium extraction would be built, in part, from the mineral it seeks to make less central. ASANA has framed this as a shift from selling Alexandrium as ore to embedding small quantities of it in high-value manufactured goods, and it has directed the Royal University of Parap to study an Alexandrium-graphene variant that reduces the mineral content of the cable. The same paradox runs through Projet Horizon, which builds Alexandrium-free collider magnets, and the two programs share the diversification thesis that value should move from the raw commodity to what is made from it.
Organization and governance
Programa Wichay is administered by ASANA under the Department of Research and Development, which also oversaw the Frontera Program and the Inti demonstrator. Technical direction rests with the Nouvelle Alexandrie Aerospace Development Directorate (NAADD), whose experience with large deployable structures on the Interstellar Research and Communication Array (IRCA) and with the Inti sail-deployment mechanism made it the natural home for tether engineering. Javelin Industries is the principal contractor for the cable, the launch vehicle, and systems integration, and the National Research and Development Corporation administers the program's open, dual-use research in the same role it holds for the civil tracks of Projet Faisceau.
Within NAADD the work is grouped under a dedicated tether-engineering office, which the Directorate has described as fusing two of its existing competencies: the orbital deployment mechanisms it built for IRCA and Inti, and the load-bearing tether engineering developed for the aerostat radar pickets of Programa Cóndor. Feasibility work is organized as a numbered phase program. Phase I, funded through 1762 AN, covers concept definition, materials research, and a rendezvous study, and the program's charter states that no operational claim will be made ahead of a demonstrated capture. Principal investigator for the Phase I study is Dr. Koyllur Ccopa, an ASANA systems engineer who worked on the Inti deployment mechanism.
Funding follows the diversification model established by the Federation's other technology programs. The advanced-sciences strand of the Aldurian Economic Diversification and Recovery Act, 1755 carries the study, and the Aldurian Development Corporation adds a matching contribution to move any resulting materials and manufacturing methods toward industry and export. The program takes no money from defense appropriations and is not tied to the Economic Emergency and Recovery Act, 1758.
Concept and design
A momentum-exchange tether is a cable placed in orbit and set turning end over end about its center of mass, with a counterweight at the far end. The study proposes to build that counterweight from spent MSS CelestiaX upper stages left in orbit, sparing the cost of lifting dedicated ballast. As it turns, the lower tip periodically swings down toward the upper atmosphere, and at the bottom of each swing it moves slowly relative to the ground below. A vehicle that reaches that point does not need to accelerate all the way to orbital velocity; it needs only to match the tip and attach. The tether then carries the payload up through half a rotation and releases it near the top of the swing, where the tip is moving faster than orbital speed for that altitude, and the payload coasts on to a higher orbit. The scheme moves the hardest part of reaching orbit, the final acceleration, from an expendable rocket stage to a reusable structure.
Tether and materials
The cable is the program's central problem. A tether must carry both the payload and its own weight over a length of hundreds of kilometers, so its usefulness is set by specific strength, the ratio of tensile strength to density. Javelin Industries has produced Alexandrium-reinforced composites with tensile strengths above 7 gigapascals while keeping the flexibility and corrosion resistance a rotating cable needs, and these are the baseline material for the study. The Royal University of Parap, which developed the Alexandrium-graphene lattice technique in 1742 AN, and the Institute for Civil Engineering and Materials Science lead the materials research, including a graphene-dominant variant intended to cut the cable's Alexandrium content. The study treats a tapered cable, thicker at the center than at the tips, as the means of holding stress within the material's limit along the whole length.
Rendezvous and capture
Programa Wichay would use an existing vehicle rather than a new one for its first captures. The MSS CelestiaX, the two-stage launcher Javelin flies for ASANA, flies its first stage back to a horizontal landing on a runway, and the study designates that reusable flyback booster as the vehicle that would meet the tether's lower tip. Capture demonstrations would fly from launch complex EL-38 at the Delgado Space Flight Center, the equatorial spaceport on Taras island from which Inti was launched, whose position near two degrees north suits the orbital geometry a tether requires. The rendezvous is the hardest operational step, because the booster and the tip must reach the same point at the same instant within a narrow margin, and the study's rendezvous work is directed at whether existing guidance can hold that tolerance.
Station-keeping and reboost
A tether loses orbital energy each time it throws a payload upward, and a working skyhook must restore that energy or decay. The Federation has direct experience of orbital decay in the Aurora Space Station, whose first module reached orbit in 1715 AN and which disintegrated in 1725 AN once it was no longer maintained. The reboost track studies two answers. An electrodynamic tether would push against the planet's magnetic field using current drawn from onboard power, restoring momentum without propellant. A second option would beam power to the tether from elsewhere, reusing the power-beaming research of Projet Faisceau and the orbital collection of Javelin's Solar Orbital Power program. Both approaches keep to the propellantless principle that Inti demonstrated.
Industrial base
The program draws on the industrial base already built for the Federation's other space and materials work. Javelin Industries supplies the composite cable, the CelestiaX launch vehicle, and integration; ESB Thermodynamics contributes thermal management and deployment hardware, as it did for the Inti sail; and NAADD provides the deployment engineering. Materials research runs through the Royal University of Parap and the Institute for Civil Engineering and Materials Science. ASANA has presented this reuse of established suppliers as a deliberate feature of the diversification programs, which are meant to deepen a domestic capability rather than stand up a new base for each project.
Technical limitations
Programa Wichay has produced no hardware, and its charter records the distance between concept and capability plainly. The tether material, though the strongest in Federation manufacture, sits close to the margin a full-length rotating cable would demand, and the graphene-dominant variant is unproven at length. Rendezvous with a moving tip at the needed precision has not been demonstrated. A deployed tether would meet the same debris and atomic-oxygen environment that ended the Aurora station, across a far larger structure. The concept also depends on a mature, low-cost reusable vehicle to reach the tip, which the CelestiaX booster approaches but has not made routine. The program treats each of these as a Phase I study question rather than a settled result.
Reception
Fred Strong, Vice-President of the Government and Secretary of Defense, welcomed the study while cautioning against reading it as more than that, repeating the line he had used on the Inti and collider programs that a feasibility framework proves a method rather than an industry. Opposition figures were sharper. Yuiza Bohi'o of the Wakara People's Party argued that money spent on an orbital tether was money not spent on the outer regions and island communities, and Francisco Gabaza of the Federal Consensus Party questioned the borrowing behind the diversification appropriations. Marcos Ferreira Gonçalves of the Democratic Socialist Party warned that concentrating the work in a few established contractors favored prestige projects over need. Dr. Rodrigo Castellanos of the Institute for Strategic Studies, whose report The Alexandrium Horizon had framed the diversification debate, asked whether a tether study earned its place in a constrained budget while nearer-term diversification work went unfunded.
