The record

Seventy-five years, and the four of them in which nothing happened

The Foundation was filed in 2000. The work it was built on starts in 1951, in a mountain observatory whose grant had lapsed, and runs through a lunar decade, a computing decade, two years of pure paperwork and a seventeen-year survey. This is the whole of it, with the reference numbers, so that anybody can check it.

Before the Foundation

The prior record

The Foundation did not exist, and nothing in this era is its achievement. What existed was a series of private endowments, made quietly, to people who were doing the right work in places where the money had run out. Our archive catalogued them in 2001 as the prior record, and the Foundation claims no credit for any of it.

They are listed here for one reason: every specification the Foundation writes today cites at least one of them, and the work would otherwise be lost. Sums are restated in credits at constant 2000 value.

1951PR-1951-01

Plate spectroscopy at Mount Sabel

Three winters of photographic spectra of Mars at opposition, funded through an observatory visitors’ fund after the station’s own grant lapsed. Forty-seven usable plates.

The result was the first internally consistent seasonal carbon-dioxide exchange estimate taken from a single site, and it is still the earliest entry in our atmosphere series.

Programme LODESTONE

The lunar-era instruments

For fifteen years the endowments went to the Moon — three separate times, for three unrelated reasons. Ranging had to be proved before anybody could navigate; the interior had to be heard before anybody could trust a foundation; and the dust had to be understood before anybody could plan to live in it.

None of this bought a ride. The instruments were built and handed to payload integrators operating vehicles that were not ours, on the single condition that has applied to every award since 1951: the data is published, in full, without embargo. It always was, and we never once had to ask for it.

1969LODESTONE/I

Tranche I opened — because the ranging had to be proved

Design freeze on a passive corner-cube retroreflector array: 104 fused-silica cubes in an aluminium frame, no power, no moving parts, nothing to fail.

1984–1987: the waiting years. The record contains no new commitments for four years. No programmes were opened, no grants awarded, no instruments built. The archive’s standing explanation is the one given at the time: the machines were not good enough yet, and there was no honest way to spend money on the problem until they were.
1988–1997
Programmes MERIDIAN and LATTICE

The decade spent on arithmetic

Two programmes ran in parallel for nine years and neither of them built anything that left the ground. MERIDIAN was a model of the Martian atmosphere. LATTICE was the memory to run it in, because every machine that could hold the model was losing to single-bit errors faster than the model could converge.

It was, on paper, the least ambitious decade in the record. It is the one that made the rest possible: by 1997 there was a defensible answer to the only question a lander programme has to answer first, which is where a vehicle can be put down without guessing.

1988MERIDIAN/01

MERIDIAN opened

A general circulation model, first run: 42 days of wall time to simulate 11 days of weather.

It was wrong. Nold’s opening report makes the important point about it — that it was wrong in a way that could be measured, which is the only useful kind of wrong.

The Foundation is filed

For forty-nine years the money had moved quietly and belonged to no institution. There was no board, no audit, no letterhead and no name — only endowments, a ledger, and a great deal of postage.

On 14 March 2000 all of it was put inside a filing. Nothing about the direction changed. What changed was that the work now had a registration number, a board that could be voted against, accounts that could be audited, and a covenant that could be enforced against the Foundation itself.

Programme PLUMBLINE and family

Seventeen years of site survey

The Foundation has never operated a vehicle on Mars. It has paid for instruments carried on vehicles operated by others, which is roughly two orders of magnitude cheaper and returns the same numbers. The condition of award is the one from 1951: publish.

Because the operators publish, the Foundation has never once had to request data from a surface vehicle. It reads what everybody else reads, on the day everybody else reads it, and spends its money on the instrument instead of the spacecraft. That was the whole arrangement.

The purpose of the survey was not discovery. It was elimination: three hundred and twelve candidate sites down to a number small enough that a crew could be sent to one of them on purpose.

A small machined optical head bolted to a black anodised baseplate, photographed on a plain grey bench. The body is bright milled aluminium with a circular front aperture in a brass retaining ring, knurled brass fibre fittings on the top and left faces, a micrometer adjuster with a black knurled knob on the right, and socket-head screws throughout.
Plate 1 — Errazuriz’s combined Raman and laser-breakdown head, photographed at the Aldern Works in 2004 on the day it was crated. 1.9 kg including the radiator; 532 nm source, 1.9 m standoff, 40 µm slit, detector at −40 °C. The two brass fittings are the fibre feed-throughs, in brass because the head was qualified cold and a plated shell cost less than a second qualification campaign; the adjuster on the right sets the slit and is wired shut before flight. It flew in 2007 and returned mineralogy for six years against a design life of two.

The vessel gets built

The Foundation is not going to Mars in 2027. In 2027 it begins building the thing that goes, and begins putting the plant on the ground that has to be working before anybody is asked to live beside it.

The schedule below is tied to the transfer windows, which are not negotiable and are known to eleven hours — a figure the Foundation owes to four people with mechanical calculators in 1958. Cargo precedes crew by two windows in every case. Nobody is sent to a site that does not already have power, water, shelter and a spare of each.

Construction authorised

Board authorisation for the first hull: LB-1, 68.4 m overall, a 1.4 MWe reactor-electric stage, two 148 m² radiators, a pressure hull of 412 m³ with six berths, and 142 t of water forward doing two jobs at once.

Articles are built at the Aldern Works and assembled in orbit. The vessel is never intended to touch either surface.

Window 1 — the plant goes first

Three tender flights to Thessaly Bench: the power plant, the sinter works that makes the landing pad and the shielding slab, and a consumables cache with a spare of everything on the critical list.

Manifest TDR-01 runs to 11,904 line items. The Foundation publishes all of them, and is aware that no inspector has yet finished reading one.

Window 2 — shelter, and a shakedown

Habitat shells one and two, the water plant, and LB-1 itself flying the crossing uncrewed with the full consumable load aboard and nobody in it.

If the shakedown transit fails, the 2031 crew does not fly. That is written into the programme rather than left to judgement.

Window 3 — first crew

Six people, 258 days out, to a site with two habitat shells, a working power plant, a sintered pad, a water plant and four years of cargo already on the ground.

They are not settlers and the Foundation does not use the word. They are the first crew of a permanently occupied station, and they come home in 2033.

Window 4 — rotation, not expansion

LB-2 carries the second crew out and LB-1 brings the first crew home. The station is occupied continuously from this window onward, by rotation rather than by growth.

Window 5 — permanence

Third rotation, expansion shells four and five, and the point at which the station’s consumables are produced locally faster than they are consumed.

That is the condition the Foundation was filed to reach. The charter says nothing about what happens afterwards.

None of the above is a promise. It is a schedule, which is a different kind of document. The Foundation has held one since 1951 and has missed dates on it before — the 1984 to 1987 gap is four years of missed dates — and it publishes the misses in the same place and the same type as the rest.
Manifest excerpt

TDR-01, twelve lines of eleven thousand nine hundred and four

Every tender manifest is published in full before flight, at the line-item level, with masses to one decimal place and a criticality letter. The Foundation is aware that this is more detail than anybody wants and publishes it anyway; the covenant does not have an exception for tedium.

A note on the record

Seventy-five years is not patience. It is bookkeeping.

Nothing in this history was achieved by anybody working alone, and very little of it was achieved quickly. The 1962 conclusion that shielding is a water problem waited thirty-four years for a number and fifty-one for a measurement. The 1958 transfer tables waited sixty-nine years to be used, and were eleven hours out when they were.

The Foundation’s only real method is to keep the ledger, keep the archive open, and still be here in the year the number is finally needed. The programmes are here, and the grant record is here, line by line.
