NASA's Science Mission Directorate is preparing to fundamentally reshape how it chooses the robotic probes, telescopes, and Earth-observing satellites that carry out its science — replacing a selection pipeline that officials now concede has become too slow, too expensive, and too unpredictable for the community it serves.

In a letter addressed to the NASA science community and titled "Faster to Science," the directorate announced it will roll out a new framework called Competition Model 2.0 (CM 2.0), and will explain the changes at a virtual NASA Science Town Hall on Monday, Oct. 26, broadcast from NASA Headquarters. The event is billed as both a briefing and a question-and-answer session for researchers, institutions, and industry partners who compete for the agency's science missions.

What NASA is changing

The core promise is speed. Under the current two-step process, mission concepts can take years to move from proposal to selection, consuming significant resources from both the agency and the research teams that submit them. NASA says CM 2.0 is intended to shorten that timeline, smooth out contract management, and give scientists a clearer, more predictable path from idea to flight.

Administrator Jared Isaacman has explicitly empowered the Science Mission Directorate to act, directing it to "accelerate the delivery of science, reduce the time and resources spent on long competitive processes, and focus funding on the highest-priority missions across every NASA Science division as quickly and affordably as possible."

The letter is unusually candid about the agency's own shortcomings, acknowledging years of complaints from researchers about the burden of bringing ideas forward:

"We have heard you. We have listened. We know that the burden of bringing great ideas forward has been too heavy for too long. It has taken years to move mission concepts through the current two-step process. This has often come with contract management challenges, unpredictability, and not enough funding."

Why now

NASA's science portfolio spans astrophysics, planetary science, Earth science, heliophysics, and biological and physical sciences, each shaped by a decadal survey produced by the National Academies and each competing for a share of a constrained budget. The traditional architecture — in which concepts mature through increasingly formal proposal stages, often across multiple years — has long been criticized as favoring large, established institutions with the resources to sustain repeated bids.

Officials framed the overhaul as a matter of institutional credibility as much as efficiency. "Predictability in delivering incredible science will be at the forefront of what we do," the letter states, signaling that the agency sees reliable, on-schedule mission delivery as essential to sustaining political and public support.

A staged, deliberately cautious rollout

Despite the ambition, NASA is signaling that the transition will not be abrupt. The directorate said changes will be implemented in stages, that some will take time to fully take effect, and that the agency intends to refine the model with community input along the way — an acknowledgment that past reform efforts have foundered when they were imposed without buy-in from the researchers who depend on the process.

  • The venue: A virtual town hall from NASA Headquarters, open to the science community.
  • The date: Monday, Oct. 26, with questions from participants fielded live.
  • The message: Faster selections, fewer years lost to competition, and funding concentrated on the highest-priority science.

The questions that remain

The letter does not spell out how many competitions will be held, how the two-step structure will be replaced, or whether smaller and early-career research teams will gain or lose ground. Those details are likely to dominate the town hall.

The central tension is one that has shadowed every NASA reform effort: speed and predictability are valuable, but competitive, peer-reviewed selection is what gives the agency's science its legitimacy. A process that moves too quickly, or that concentrates funding on a narrower set of priorities, risks alienating the very community NASA is courting. Conversely, a process that remains slow risks losing missions to cost growth and delays — and, increasingly, to rival space programs abroad and a growing commercial space sector at home.

For now, the agency's framing is one of responsiveness rather than rupture. "We are committed to getting this right," the letter states, pairing urgency with a promise of careful, iterative implementation. Whether that balance holds will be tested the moment the first missions are selected under the new rules.
