Dear NASA Science Community,
NASA Science wants to deliver science faster, so we’re changing how we compete and select missions. On Monday, October 26, we will host a virtual NASA Science Town Hall, from NASA Headquarters, to explain our new Competition Model 2.0 (CM 2.0), and answer your questions.
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. NASA is committed to doing better — and I’m excited to share with you how we’re making it happen.
I am so pleased that NASA Administrator Jared Isaacman has empowered the Science Mission Directorate to take action and make our mission selection process move more smoothly, efficiently, and effectively. The Administrator has directed us 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. Predictability in delivering incredible science will be at the forefront of what we do.
We are committed to getting this right. Some of these changes will take time to fully implement. We will roll them out in stages, be thoughtful about them, and refine them with your input along the way. But time is also of the essence. By streamlining how missions are proposed, reviewed, and selected, we can make meaningful change right now. That streamlined approach is Competition Model 2.0, or CM2.0, and it is how we are answering the Administrator’s call to get you to science faster.
CM2.0 starts from a simple idea: compete on the science first. Proposals will be science-focused and will not require detailed engineering plans, cost, and implementation work until they are truly needed to make a decision. This frees you to spend more of your time doing science and less of it proposing how to do science.
Here is how we will streamline mission selection across our mission classes:
CM2.0 will not change how we manage our largest missions since that process has already been reformed. After the James Webb Space Telescope, NASA conducted the Large Mission Study which drew lessons from Webb and best practices from our most successful flagships into a single, documented approach for building large missions more efficiently. Flagships will continue to follow that approach, with NASA directing the overall mission to a lead NASA Center and it will then compete the science teams and instruments through targeted solicitations.
These missions will move to a new, accelerated two-step competition:
These updates in the mission selection process will reduce time from AO to step 2 selection by up to 45 percent. This means that the original 35-months timeline will be reduced to about 19.5 months, all while having a stronger, more mature mission at the time of selection.
These missions follow the same two-step approach with an even broader field of implementing organizations, including universities and industry partners. Implementing organizations and partners will be evaluated on past performance on projects of similar complexity and cost prior to mission selection. PI-led teams can request pairing with either a Goddard or JPL implementation team at Step 1 selection, and NASA can provide Center support where it will help with procurement, contract management, or quick resolution of technical challenges. This will result again in an up to a 45 percent reduction in the selection timeline.
These missions will move to a single-step competition with a smaller review team and virtual site visits. They will also be open to a broad range of implementing organizations. The time to final selection will drop from about 32 months to about 19 months which is a reduction of up to 40 percent. Our smallest missions will be riding the momentum of a maturing commercial space economy and will move even faster. This means more missions, more often, with more incredible science at a lower cost.
The commercial space industry has never been stronger—and it’s only gaining momentum. Mission and implementation teams will be expected to adopt industry best practices and emerging commercial capabilities, including commercial buses, subsystems, and multi-mission operations — wherever they offer a technical or cost benefit. No mission class is too large or too complex to benefit from the commercial industry. We will keep assessing the commercial landscape at regular intervals, building on our recent Science as a Service Request for Information.
By competing on science first, established teams and first-time teams stand on equal footing. The best idea wins.
Great science deserves great stewardship. Rigorous cost and schedule control remains mandatory across every mission class. Phase A estimates will inform complexity and scope trades. Therefore, breaches of control thresholds will carry real consequences of up to, and including, mission termination. That discipline is how we keep the pipeline flowing for everyone.
Our NASA Centers lead the world in spaceflight experience. Therefore, by appropriately directing work at Goddard and JPL, we will save taxpayer dollars, eliminate unnecessary competition among NASA Centers, encourage collaboration, and keep critical skills thriving across the agency.
This is a moment of real opportunity. We have an administrator who is empowering us to move faster and a commercial market that is ready to help. We have NASA Centers with unmatched expertise, and a science community whose ideas expand and redefine the bounds of human achievement in the cosmos. CM2.0 brings those strengths together so that more great ideas become great missions, all while being faster and returning more science at an affordable price for the benefit of all.
NASA leads the world in discovery and innovation, but none of that happens on its own. It happens because of you. You are the reason the list of what’s “impossible” keeps getting shorter. I am so proud of what this community has achieved, and what incredible science we will continue to discover together
Thank you for your brilliance, your dedication, and your partnership. The best of NASA Science is still ahead of us, and I cannot wait to see where this journey takes us.
With gratitude and excitement,
Nicola Fox, associate administrator, Science Mission Directorate, NASA Headquarters

NASA tested RS-25 engine No. 10001 on Oct. 21 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
Test teams fired the developmental engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during launch of NASA’s SLS (Space Launch System) rocket.
During the test, operators also fired the engine up to the 111% power level, matching the thrust needed for new production engines to launch the SLS rocket and the Orion spacecraft to orbit.
The main objectives of the test were to acceptance test RS-25 flight components for future Artemis missions and validate the new thermal protection system, which protects the RS-25 engine nozzle from the thermal environment surrounding SLS during launch.
While this developmental engine will not be used in flight, the hot fire test provides NASA and NASA’s prime contractor L3Harris Technologies with the capability to capture critical data to improve engine performance and reliability.
Four RS-25 engines produce up to 2 million pounds of combined thrust to help launch the SLS rocket for each Artemis mission.
All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use. Tests are conducted by a team of operators from NASA, L3Harris, and Nova Space Solutions.

Interstellar probes. Lunar drones. Helicopters on Mars.
When a group of Caltech graduate students and enthusiasts began conducting rocket-propulsion tests in Pasadena’s Arroyo Seco on Oct. 31, 1936, they had no idea that their work marked the inception of the Jet Propulsion Laboratory. Ninety years later, the lab, now managed by Caltech for NASA, isn’t only celebrating the long line of historic firsts accomplished here; it’s paving the way for many to come.
Initially a contractor for the U.S. Army, JPL launched America’s first satellite, Explorer 1 in 1958. But rather than just orbiting Earth like the Soviet Union’s Sputnik, Explorer 1 became the first spacecraft to conduct science, thanks to an onboard Geiger counter that discovered the protective radiation belts encircling Earth.
The lab joined part of the newly formed NASA that same year. Within six years, in 1964, JPL sent the first U.S. mission to the Moon, Ranger 7. It also went on to lead the first planetary flyby, the first probe to visit all four gas giants, the first infrared telescope, the first rovers to roll on Mars, and the first rotorcraft to fly there, among many other historic milestones.
More firsts are on the way.
“Over the course of 90 years, JPL’s first-of-a-kind missions have transformed our understanding of the universe and our place in it,” said Dave Gallagher, JPL’s director since 2025. In 1992, only a couple years after he started as an engineer at the lab, Gallagher led the JPL team that built and tested the Wide-Field and Planetary 2 Camera for NASA’s Hubble Space Telescope, which delivered many of the mission’s most iconic images. “We stand on an extraordinary foundation, and we’re ready to push the boundaries with exciting new missions so that future generations can go even further.”
Aiming for a 2028 launch, the JPL-managed SkyFall mission will deploy three helicopters mid-descent over Mars to search to map hidden ice deposits and analyze weather patterns. Helping advance NASA’s Moon Base, JPL is developing MoonFall, a mission that will land a group of large propulsive drones at the lunar South Pole that same year. Set for a 2027 launch, SunRISE (Sun Radio Interferometer Space Experiment) features six toaster-oven-size satellites that will fly in formation to create a miles-wide radio antenna dish in order to study the Sun’s activity. What it reveals could help make space exploration safer for humans.
Protecting humanity is also the goal of the asteroid-hunting NEO Surveyor (Near-Earth Object Surveyor) mission, which, managed by JPL, will hunt for potentially hazardous space rocks that other telescopes can’t find. Once an object is spotted, NASA can offer a threat assessment and plan accordingly.
Closer to home, the same lab that launched the first oceanographic satellite in 1978 is at work on several missions that will offer a deeper reading of Earth’s vital signs. Where one mission will monitor the movement of water by measuring slight changes in gravity, another will study how powerful tropical convective storms form. A third will detail how different types of air pollution affect human health.
They add to a fleet of other Earth missions and projects JPL helps lead, including NISAR (NASA-ISRO Synthetic Aperture Radar) a joint mission with the Indian Space Research Organisation that can pinpoint how Earth’s surface changes in relation to natural disasters. Another, one of a series of instruments called AVIRIS (Airborne Visible Infrared Imaging Spectrometer), can even detect rare Earth elements critical to modern technology.
Flown on airplanes, the AVIRIS sensors were developed at JPL’s Microdevices Laboratory, which invented the “camera on a chip” technology that enables cellphones to take pictures. It’s also where the detectors are being developed for PRIMA (PRobe far-Infrared Mission for Astrophysics), a newly announced NASA mission that will strengthen humanity’s understanding of the universe by studying radiant energy visible only in the far-infrared.
“Bringing together the very best of scientific brilliance and engineering ingenuity from across Caltech and JPL continues to advance NASA’s priorities and empower America’s space leadership,” said Caltech’s president Ray Jayawardhana, who is also a professor of astronomy. “I can only imagine what those Caltech students experimenting with rockets in a little patch of dry riverbed would think if they could to see what Caltech and JPL have accomplished since, and where we’re headed next. Ninety years later, the same spirit of daring is still opening new frontiers and inspiring humanity.”
The 90th anniversary comes just a few weeks before another milestone, when on Nov. 18 Voyager 1 reaches a full light-day — the distance light will travel in 24 hours, which is some 16 billion miles, or 26 billion kilometers — from Earth. Ed Stone led the mission for 50 years, serving as JPL’s director for 10 of them. Stone died in 2024, but the Voyagers are continuing on their journey deeper into interstellar space, a place no other spacecraft have ventured. Turning 50 next year, they rely on NASA’s Deep Space Network (developed by JPL in the Apollo era) to receive commands and send back science data. Stone said that with both Voyagers exploring regions never before visited, “every day is a day of discovery.” The same could be said for JPL.

Since the last blog update, Perseverance has achieved a major milestone on Mars. On Sol 2006 (Oct. 11, 2026), its odometer reached 45.22 kilometers (28.10 miles), setting a new record for the farthest distance driven on another celestial body. Its engineering twin here on Earth even received a plaque from Guinness World Records celebrating the achievement.
Two months ago, on Sol 1947, the odometer sat about 200 meters away from the milestone, a distance easily achievable with a single drive using Autonomous Navigation (AutoNav). However, the rover found itself in a very scientifically interesting area and spent time executing short drives to perform rock abrasions and proximity science on ancient rock outcrops. When Perseverance was finally ready to move on to a new site, it sailed past the record.
On its way to the drive record, Perseverance has navigated challenging terrain while also pioneering new ways to drive across the Martian surface. Perseverance’s various encounters with dense boulder fields and steep slopes have pushed the team to re-evaluate driving guidelines so the rover is better prepared to handle tough terrain. After running thousands of simulations, the team raised the rover’s tilt limit to 24 degrees and reduced the clearance required under the rover’s belly pan to 20 centimeters (about 7.9 inches). The team also updated the rover’s braking software to avoid rock hazards, nearly doubled steer motor current limits, updated flight software with “dynamic slip tables” to model expected slip, and used cross-slope driving to better anchor wheels on exposed bedrock.
One of the most exciting updates the team has made is an autonomous drive capability called onboard Global Localization (GBLC). GBLC repurposes the high-speed commercial processor inside the Ingenuity Helicopter Base Station to compare ground and orbital imagery to autonomously locate the rover in global coordinates at the end of a drive (as though we had GPS on a world without it), enabling Perseverance to drive longer distances without human intervention. Unlike Perseverance’s main flight computer, this coprocessor is not hardened against the punishing radiation environment of the Martian surface, where a thin atmosphere and the lack of a global magnetosphere leave little shielding. This radiation can induce “transient bit flips” in memory the software needs to function, and the team developed an effective software-based approach to radiation hardening. Looking forward to the greater demands of longer drives and to planning more activity with fewer resources, the team is also exploring the use of generative SI to help efficiently propose solutions to steer AutoNav along the many legs of a strategic path.
The team is using hard-won lessons from 45 kilometers (more than 28 miles) of driving to reinvent how the rover drives across the Martian surface. As Perseverance climbs higher along the crater rim, the next leap in autonomous exploration on Mars is just getting started.
