This photo shows the Optical Telescope Assembly for NASA’s Nancy Grace Roman Space Telescope, which was recently delivered to the largest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md.NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope is one giant step closer to unlocking the mysteries of the universe. The mission has now received its final major delivery: the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror, nine additional mirrors, and supporting structures and electronics. The assembly was delivered Nov. 7. to the largest clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the observatory is being built.
The telescope will focus cosmic light and send it to Roman’s instruments, revealing many billions of objects strewn throughout space and time. Using the mission’s Wide Field Instrument, a 300-megapixel infrared camera, astronomers will survey the cosmos all the way from the outskirts of our solar system toward the edge of the observable universe. Scientists will use Roman’s Coronagraph Instrument to test new technologies for dimming host stars to image planets and dusty disks around them in far better detail than ever before.
“We have a top-notch telescope that’s well aligned and has great optical performance at the cold temperatures it will see in space,” said Bente Eegholm, optics lead for Roman’s Optical Telescope Assembly at NASA Goddard. “I am now looking forward to the next phase where the telescope and instruments will be put together to form the Roman observatory.”
In this photo, optical engineer Bente Eegholm inspects the surface of the primary mirror for NASA’s Nancy Grace Roman Space Telescope. This 7.9-foot (2.4-meter) mirror is a major component of the Optical Telescope Assembly, which also contains nine additional mirrors and supporting structures and electronics.NASA/Chris Gunn Designed and built by L3Harris Technologies in Rochester, New York, the assembly incorporates key optics (including the primary mirror) that were made available to NASA by the National Reconnaissance Office. The team at L3Harris then reshaped the mirror and built upon the inherited hardware to ensure it would meet Roman’s specifications for expansive, sensitive infrared observations.
“The telescope will be the foundation of all of the science Roman will do, so its design and performance are among the largest factors in the mission’s survey capability,” said Josh Abel, lead Optical Telescope Assembly systems engineer at NASA Goddard.
The team at Goddard worked closely with L3Harris to ensure these stringent requirements were met and that the telescope assembly will integrate smoothly into the rest of the Roman observatory.
The assembly’s design and performance will largely determine the quality of the mission’s results, so the manufacturing and testing processes were extremely rigorous. Each optical component was tested individually prior to being assembled and assessed together earlier this year. The tests helped ensure that the alignment of the telescope’s mirrors will change as expected when the telescope reaches its operating temperature in space.
Then, the telescope was put through tests simulating the extreme shaking and intense sound waves associated with launch. Engineers also made sure that tiny components called actuators, which will adjust some of the mirrors in space, move as predicted. And the team measured gases released from the assembly as it transitioned from normal air pressure to a vacuum –– the same phenomenon that has led astronauts to report that space smells gunpowdery or metallic. If not carefully controlled, these gases could contaminate the telescope or instruments.
Upon arrival at NASA’s Goddard Space Flight Center, the Optical Telescope Assembly for the agency’s Nancy Grace Roman Space Telescope was lifted out of the shipping fixture and placed with other mission hardware in Goddard’s largest clean room. Now, it will be installed onto Roman’s Instrument Carrier, a structure that will keep the telescope and Roman’s two instruments optically aligned. The assembly’s electronics box –– essentially the telescope’s brain –– will be mounted within the spacecraft along with Roman’s other electronics.NASA/Chris Gunn Finally, the telescope underwent a month-long thermal vacuum test to ensure it will withstand the temperature and pressure environment of space. The team closely monitored it during cold operating conditions to ensure the telescope’s temperature will remain constant to within a fraction of a degree. Holding the temperature constant allows the telescope to remain in stable focus, making Roman’s high-resolution images consistently sharp. Nearly 100 heaters on the telescope will help keep all parts of it at a very stable temperature.
“It is very difficult to design and build a system to hold temperatures to such a tight stability, and the telescope performed exceptionally,” said Christine Cottingham, thermal lead for Roman’s Optical Telescope Assembly at NASA Goddard.
Now that the assembly has arrived at Goddard, it will be installed onto Roman’s Instrument Carrier, a structure that will keep the telescope and Roman’s two instruments optically aligned. The assembly’s electronics box –– essentially the telescope’s brain –– will be mounted within the spacecraft along with Roman’s other electronics.
With this milestone, Roman remains on track for launch by May 2027.
“Congratulations to the team on this stellar accomplishment!” said J. Scott Smith, the assembly’s telescope manager at NASA Goddard. “The completion of the telescope marks the end of an epoch and incredible journey for this team, and yet only a chapter in building Roman. The team’s efforts have advanced technology and ignited the imaginations of those who dream of exploring the stars.”

Video: 00:06:45 Smile is the Solar wind Magnetosphere Ionosphere Link Explorer, a brand-new space mission currently in the making. It will study space weather and the interaction between the solar wind and Earth’s environment.
Unique about Smile is that it will take the first X-ray images and videos of the solar wind slamming into Earth’s protective magnetic bubble, and its complementary ultraviolet images will provide the longest-ever continuous look at the northern lights.
In this first of several short videos, David Agnolon (Smile Project Manager) and Philippe Escoubet (Smile Project Scientist) talk about the why and the how of Smile. You’ll see scenes of the building and testing of the spacecraft’s payload module by Airbus in Madrid, including the installation of one of the European instruments, the Soft X-ray Imager from the University of Leicester.
Smile is a 50–50 collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). ESA provides the payload module of the spacecraft, which carries three of the four science instruments, and the Vega-C rocket which will launch Smile to space. CAS provides the platform module hosting the fourth science instrument, as well as the service and propulsion modules.

JPL is a research and development lab federally funded by NASA and managed by Caltech. NASA/JPL-Caltech Workforce statement and memo to employees
JPL statement issued on Nov. 12, 2024:
While we have taken various measures to meet our current FY’25 budget allocation, we have reached the difficult decision to reduce the JPL workforce through layoffs. This reduction affects approximately 325 of our colleagues, an impact of about 5% of our workforce. The impacts are occurring across technical, business, and support areas of the Laboratory. These are painful but necessary adjustments that will enable us to adhere to our budget while continuing our important work for NASA and our nation.
The following is a memo sent earlier today from JPL Director Laurie Leshin to employees:
Dear Colleagues,
This is a message I had hoped not to have to write. I’m reaching out to share the difficult news that JPL will be taking a workforce action tomorrow, Nov. 13, resulting in a layoff of approximately 325 of our colleagues, or ~5% of our workforce. Despite this being incredibly difficult for our community, this number is lower than projected a few months ago thanks in part to the hard work of so many people across JPL. The workforce assessment conducted as part of this process has been both extensive and thorough, and although we can never have perfect insight into the future, I sincerely believe that after this action we will be at a more stable workforce level moving forward.
How we got here:
During our last town hall, I discussed our continued funding challenges and projections of what the potential impact on our workforce could look like. I shared that we had been working through multiple workforce scenarios to address the dynamic funding environment, and that we have been doing everything we can, in partnership with our colleagues at NASA and elsewhere, to minimize adverse effects on JPL’s capabilities and team.
Unfortunately, despite all these efforts, we need to make one further workforce reduction to meet the available funding for FY’25. This reduction is spread across essentially all areas of the Lab including our technical, project, business, and support areas. We have taken seriously the need to re-size our workforce, whether direct-funded (project) or funded on overhead (burden). With lower budgets and based on the forecasted work ahead, we had to tighten our belts across the board, and you will see that reflected in the layoff impacts.
As part of our workforce assessment and determining where reductions are being made, we have taken time to complete a full review of our competencies, future mission needs, and we have established guidance for our core capabilities across the Laboratory. We have worked closely with the Executive Council, division managers, project leadership and others to ensure we maintain the appropriate levels of technical expertise, capacity for innovation, and ability to deliver on an exciting future for JPL. Our focus will continue to be on empowering managers to support their teams through this action and equipping all of us with a variety of resources as we move forward together.
Here are the details about what will happen tomorrow:
Unless notified otherwise, all employees are required to work from home tomorrow Nov. 13, regardless of their telework status. Tomorrow you will be invited to a short, virtual, Lab-wide meeting with myself and Deputy Director Leslie Livesay at 9:30 a.m. We will relay the details of where we are in the process and what to expect. Please look out for the meeting notification that will follow this memo. There will not be organization-level notification meetings as in February. This one meeting will provide the information needed for the entire Lab at once.
Our approach is to prioritize notifying everyone via email as quickly as possible whether their role is being affected by the layoff or not. Then we can rapidly shift to providing personalized support to our laid-off colleagues who are part of the workforce reduction, including offering dedicated time to discuss their benefits, and several other forms of assistance. Because of system limitations, the individual email notifications will take place over several hours tomorrow. A schedule of the notifications, which will occur by organization, will be shared in the virtual briefing tomorrow morning and also posted on JPL Space, the JPL HR Website, and Slack. You can also find answers to Frequently Asked Questions (FAQs) on our website here.
Our JPL Community:
I know the absence of our colleagues will be acutely felt, especially after a very challenging year for the Lab. To those leaving JPL as a result of this action, we are grateful for your many vital contributions to JPL and to NASA. We will be here to support you during this time to ensure this transition is as smooth as possible.
To reiterate to you all, I believe this is the last cross-Lab workforce action we will need to take in the foreseeable future. After this action, we will be at about 5,500 JPL regular employees. I believe this is a stable, supportable staffing level moving forward. While we can never be 100% certain of the future budget, we will be well positioned for the work ahead. This may not help much in this difficult moment, but I do want to be crystal clear with my thoughts and perspective. If we hold strong together, we will come through this, just as we have done during other turbulent times in JPL’s nearly 90-year history. Finally, even though the coming leadership transition at NASA may introduce both new uncertainties and new opportunities, this action would be happening regardless of the recent election outcome.
While I know many of us are feeling anger or disappointment with this news, I encourage everyone to act with grace and empathy toward one another, and to lean on each other for support. I will be speaking with you again very soon to discuss our path ahead. Until then, know that we are an incredibly strong organization – our dazzling history, current achievements, and relentless commitment to exploration and discovery position us well for the future.
Laurie

Sols 4359-4361: The Perfect Road Trip Destination For Any Rover!
NASA’s Mars rover Curiosity acquired this image of its workspace, which includes several targets for investigation — “Buttress Tree,” “Forester Pass,” “Crater Mountain,” “Mahogany Creek,” and “Filly Lake.” Curiosity used its Left Navigation Camera on Nov. 8, 2024 — sol 4357, or Martian day 4.357, of the Mars Science Laboratory mission — at 00:06:17 UTC. NASA/JPL-Caltech Earth planning date: Friday, Nov. 8, 2024
After the excitement of Wednesday’s plan, it was a relief to come in today to hear that the drive toward our exit from Gediz Vallis completed successfully and that we weren’t perched on any rocks or in any other precarious position. This made for a very smooth planning morning, which is always nice on a Friday after a long week.
But that isn’t to say that Curiosity will be taking it easy for the weekend. Smooth planning means we have lots of time to pack in as much science as we can fit. Today, this meant that the geology group (GEO) got to name eight new targets, and the environmental group (ENV) got to spend some extra time contemplating the atmosphere. Reading through the list of target names from GEO felt a bit like reading a travel guide — top rocks to visit when you’re exiting Gediz Vallis!
If you look to the front of your rover, what we refer to as the “workspace” (and which you can see part of in the image above), you’ll see an array of rocks. Take in the polygonal fractures of “Colosseum Mountain” and be amazed by the structures of “Tyndall Creek” and “Cascade Valley.” Get up close and personal with our contact science targets, “Mahogany Creek,” “Forester Pass,” and “Buttress Tree.” Our workspace has something for everyone, including the laser spectrometers in the family, who will find plenty to explore with “Filly Lake” and “Crater Mountain.” We have old favorites too, like the upper Gediz Vallis Ridge and the Texoli outcrop.
After a busy day sightseeing, why not kick back with ENV and take a deep breath? APXS and ChemCam have you covered, watching the changing atmospheric composition. Look up with Navcam and you may see clouds drifting by, or spend some time looking for dust devils in the distance. Want to check the weather before planning your road trip? Our weather station REMS works around the clock, and Mastcam and Navcam are both keeping an eye on how dusty the crater is.
All good vacations must come to an end, but know that when it’s time to drive away there will be many more thrilling sights to come!
