"NASA Competition Model 2.0: Science First, Half the Paperwork, and Missions in Half the Time"

NASA has decided that the hardest part of getting a science mission into space should be the science, not the paperwork. On 21 October, Nicola Fox, associate administrator of the agency's Science Mission Directorate, announced Competition Model 2.0, a reworking of how NASA picks its science missions, and on 26 October the agency held a virtual town hall to explain it to researchers. The headline numbers are striking: for the medium-sized mission classes, the journey from announcement to selection is to fall from about 35 months to about 19.5, a cut of up to 45 percent. For the smallest missions, it falls from about 32 months to about 19. The question worth asking is not whether faster is better. It is what the old slowness was quietly selecting for.

Under the old two-step process, a team competing for a Discovery, New Frontiers, or Astro-Probe mission had to arrive with much of the engineering and financial case already built before NASA had even decided the science was worth pursuing. That is a filter, and filters have biases. A proposal that demands hundreds of pages of cost and engineering detail before the science case is judged will, all else being equal, favour the institutions that already employ people who write such proposals for a living: big universities, big aerospace firms, the NASA centres themselves. A small team with a brilliant instrument idea and no proposal department starts the race a lap behind. Fox's letter put it plainly, saying the burden of bringing great ideas forward had been too heavy for too long, and that the new process would judge scientific merit first.

The new shape of the competition reflects that. For Discovery, New Frontiers, and Astro-Probes, step one now asks for just three things: a science case, a science implementation plan, and a proof-of-concept mission design, roughly half the material previously required. Only the teams that pass that test go on to step two, a mission implementation study carried out with NASA's Goddard Space Flight Center or the Jet Propulsion Laboratory, where scientific merit, implementation merit, and risk get examined properly. Medium-class Explorer and Earth Explorer missions follow the same two-step pattern but open to a wider field, including universities and commercial organisations, with applicants judged on their track record at similar size and complexity. The smallest missions go furthest: Small Explorer and Earth Venture missions, along with Missions of Opportunity, hosted payloads, and rideshares, move to a single-stage selection, with no second round of competing proposals at all. Fox's summary was deliberately blunt: more missions, more often, at lower cost.

There is a second, quieter shift inside the plan, and it cuts both ways. Goddard and JPL move from being competitors for mission work to being partners in maturing the winning concepts, and principal-investigator-led teams can ask for centre support during step one. That should mean fewer concepts dying because a university team could not navigate procurement or cost estimation alone. But it also concentrates influence in the two centres that already dominate NASA science engineering, and NASA itself acknowledges the tension, promising stricter cost and schedule controls, with breaches carrying consequences up to cancellation. The largest flagship missions, notably, are untouched by all of this: they continue under the reformed process drawn up after the James Webb Space Telescope, with a lead centre directing the mission and competing only the instruments. Reform, in other words, stops where the money gets biggest.

The timing of the announcement makes the stakes concrete. Just weeks earlier, on 23 September, NASA advanced PRIMA, the PRobe far-Infrared Mission for Astrophysics, into Phase B, the first mission of a new Probe Explorers class. With a 1.8-metre telescope, a project cost capped at 1.2 billion dollars excluding launch, and a target launch of 2033, PRIMA will be the first far-infrared space observatory since Europe's Herschel ended operations in 2013, filling a gap between Webb's infrared view and the radio sky. It is exactly the kind of mid-priced, high-value mission the new model is meant to multiply: too big for the old small-mission pipeline, too focused to wait a decade in flagship queues. But PRIMA itself was picked under the old rules, after a competition that drifted from its original 2032 launch target and 1 billion dollar cap. The new model will be judged not by PRIMA but by whatever comes after it.

That is where my own judgement comes in. A reform announced in a letter and explained in a town hall is not yet a reform; it becomes one when the first announcement of opportunity goes out under the new rules and a team that could not have afforded the old process wins a place. NASA has said some parts will take time to implement, and budgets and politics can stall even the best-designed process. Even so, the direction of travel is unambiguous, the town hall has already happened, and the agency has staked its credibility on the new timelines. I expect NASA to open at least one science mission competition under Competition Model 2.0 before the end of 2027, and the team that wins its first step will tell us more about the future of space science than any timeline NASA publishes. If that winner is a small university group rather than a familiar centre, the model will have done what it promised. If it is the usual names again, faster paperwork will have been all it ever was.
