Preparations for Next Moonwalk Simulations Underway (and Underwater)
The laser that transmits between NASA’s Psyche spacecraft and Earth-based observatories for the Deep Space Optical Communications experiment successfully reaches its target thanks, in part, to a vibration isolation platform developed by Controlled Dynamics Inc., and supported by several Space Technology Mission Directorate programs. NASA/JPL-Caltech One year ago today, the future of space communications arrived at Earth as a beam of light from a NASA spacecraft nearly 10 million miles away. That’s 40 times farther than our Moon. That’s like using a laser pointer to track a moving dime from a mile away. That’s pretty precise.
That laser — transmitted from NASA’s DSOC (Deep Space Optical Communications) technology demonstration — has continued to hit its target on Earth from record-breaking distances.
“NASA’s Deep Space Optical Communications features many novel technologies that are needed to precisely point and track the uplink beacon and direct the downlink laser,” said Bill Klipstein, DSOC project manager at NASA’s Jet Propulsion Laboratory in Southern California.
One of the technologies aiding that extremely precise pointing was invented by a small business and fostered by NASA for more than a decade.
Whole Lotta Shakin’ Going On (Not!)
Part of the challenge with the precision pointing needed for DSOC was isolating the laser from the spacecraft’s vibrations, which would nudge the beam off target. Fortunately for NASA, Controlled Dynamics Inc. (CDI), in Huntington Beach, California, offered a solution to this problem.
The company had a platform designed to isolate orbiting experiments from vibrations caused by their host spacecraft, other payloads, crew movements, or even their own equipment. Just as the shocks on a car provide a smoother ride, the struts and actuators on CDI’s vibration isolation platform created a stable setting for delicate equipment.
This idea needed to be developed and tested first to prove successful.
The Path to Deep Space Success
NASA’s Space Technology Mission Directorate started supporting the platform’s development in 2012 under its Game Changing Development program with follow-on support from the SBIR (Small Business Innovation Research) program. The technology really began to take off — pun intended — under NASA’s Flight Opportunities program. Managed out of NASA’s Armstrong Flight Research Center in Edwards, California, Flight Opportunities rapidly demonstrates promising technologies aboard suborbital rockets and other vehicles flown by commercial companies.
Early flight tests in 2013 sufficiently demonstrated the platform’s performance, earning CDI’s technology a spot on the International Space Station in 2016. But the flight testing didn’t end there. A rapid series of flights with Blue Origin, UP Aerospace, and Virgin Galactic put the platform through its paces, including numerous boosts and thruster firings, pyrotechnic shocks, and the forces of reentry and landing.
“Flight Opportunities was instrumental in our development,” said Dr. Scott Green, CDI’s co-founder and the platform’s principal investigator. “With five separate flight campaigns in just eight months, those tests allowed us to build up flight maturity and readiness so we could transition to deep space.”
The vibration isolation platform developed by Controlled Dynamics Inc., and used on the Deep Space Optical Communications experiment conducted numerous tests through NASA’s Flight Opportunities program, including this flight aboard Virgin Galactic’s VSS Unity in February 2019. Virgin Galactic The culmination of NASA’s investments in CDI’s vibration isolation platform was through its Technology Demonstration Missions program, which along with NASA’s SCaN (Space Communications and Navigation) program supported NASA’s Deep Space Optical Communications.
On Oct. 13, 2023, DSOC launched aboard the Psyche spacecraft, a mission managed by JPL. The CDI isolation platform provided DSOC with the active stabilization and precision pointing needed to successfully transmit a high-definition video of Taters the cat and other sample data from record-breaking distances in deep space.
“Active stabilization of the flight laser transceiver is required to help the project succeed in its goal to downlink high bandwidth data from millions of miles,” said Klipstein. “To do this, we need to measure our pointing and avoid bumping into the spacecraft while we are floating. The CDI struts gave us that capability.”
The Deep Space Optical Communications technology demonstration’s flight laser transceiver is shown at NASA’s Jet Propulsion Laboratory in Southern California in April 2021. The transceiver is mounted on an assembly of struts and actuators — developed by Controlled Dynamics Inc. — that stabilizes the optics from spacecraft vibrations. Several Space Technology Mission Directorate programs supported the vibration isolation technology’s development. NASA/JPL-Caltech Onward Toward Psyche
The Psyche spacecraft is expected to reach its namesake metal-rich asteroid located between Mars and Jupiter by August 2029. In the meantime, the DSOC project team is celebrating recognition as one of TIME’s Inventions of 2024 and expects the experiment to continue adding to its long list of goals met and exceeded in its first year.

Mars 2020 Perseverance Joins NASA’s Here to Observe Program
Katie Stack Morgan and Nicole Spanovich with the NASA Here to Observe Program students and faculty from Kutztown University. Kutztown University The Mars 2020 Perseverance mission has recently joined the NASA Here to Observe (H2O) program, where NASA planetary missions are partnered with universities to encourage undergraduate students from historically marginalized groups to pursue a career in STEM. As part of this program, the Perseverance mission has been paired with Kutztown University, located in Kutztown, Pennsylvania. Selected undergraduate students at the university will be able to observe and interact with Perseverance mission team members throughout this academic year to learn about the individuals who are part of the team and what it means to work on the rover mission.
To help kick off the program and our new partnership, I traveled to Kutztown along with the Perseverance Deputy Project Scientist, Katie Stack Morgan. We met several members of the Kutztown faculty and staff, toured their beautiful campus, and spent time getting to know the students participating in the H2O program this year. Katie and I were impressed by the enthusiasm and engagement exhibited by the students during our visit. We presented an introduction to the Perseverance mission including the recent discoveries, upcoming plans, and who comprises the mission team. There was also ample time to answer the many thoughtful questions about both the mission and the career paths of both me and Katie.
As part of this program, the students will observe select Perseverance mission meetings and activities. We kicked this off in October when the students observed a Geologic Context Working Group meeting to learn how scientists work together to understand the data gathered by the rover and make decisions about what the rover should do next. The students will also be paired with mentors from the Perseverance mission team throughout this academic year where they’ll have the chance to learn about the various career paths our team members have taken, read scientific papers, and prepare for a trip to the Lunar and Planetary Sciences Conference.
Overall, we have a great plan for our H2O partnership and are looking forward to welcoming Kutztown University to the Perseverance mission!

Sols 4352-4354: Halloween Fright Night on Mars
NASA’s Mars rover Curiosity acquired this image of the target surface feature nicknamed “Reds Meadow,” using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm. Curiosity captured the image Oct. 31, 2024, at 19:09:10 UTC, on sol 4350 — Martian day 4,350 of the Mars Science Laboratory Mission. NASA/JPL-Caltech/MSSS Earth planning date: Friday, Nov. 1, 2024
Yesterday evening (Thursday) was Halloween for many of us here on Earth. My neighborhood in eastern Canada was full of small (and not so small!) children, running around in the dark collecting sweets and candy but also getting scared by the ghostly decorations hung at each house. Little did we suspect that our poor rover on Mars was also getting spooked. Curiosity completed about a meter (about 3 feet) of the planned drive before becoming unsettled … scared, if you will! … when its left front wheel got hung up on a rock and stopped moving.
Luckily, we understood this kind of frightened behavior and were able to resume planning today as per usual. That meter was enough to give us a whole new set of targets to choose from. As APXS Strategic Planner this week, I had chosen darker-looking targets in the workspace — “Ladder Lake” and “Reds Meadow” (shown in the accompanying MAHLI image) — earlier in the week. I was happy that bumping backwards by a meter allowed us to reach some of the more typical pale colored bedrock at “Eureka Valley” and a second APXS analysis on “Black Bear Lake,” which is a mixture of both pale bedrock and some darker layers. MAHLI added in a bonus set of images on “Stag Dome,” focusing on small, rougher patches on the pale bedrock.
ChemCam is taking advantage of the short bump, too, adding a passive observation on the brushed Reds Meadow target, analyzed by APXS and MAHLI in Monday’s plan. A ChemCam LIBS target “Hoist Ridge” focuses on a small vertical face of dark material. Two long distance images planned for ChemCam’s Remote Micro Imager (RMI) look at the distribution of rocks along the Gediz Vallis ridge in the distance.
Mastcam is taking several mosaics this weekend (must have gotten extra energy from the Halloween sugar!). Close to the rover, Mastcam will acquire single-frame images of the targets Hoist Ridge and Eureka Valley, and a small mosaic of some surficial troughs just a little further away. Moving further afield, a small 3×1 mosaic (three images in one row) will image the same area as the ChemCam RMI of the Gediz Vallis ridge, and a larger 9×2 mosaic will focus on the faraway yardang unit, where we hopefully will be in a few years.
Then for the really big images: Mastcam will image the whole landscape in a special 360-degree view, so big it needs to be broken into two parts. The first will have 43×4 frames, the second 34×5 frames. These mosaics are huge, so we save them for when we are at a really good vantage point to allow us to capture as much detail as possible for science and engineering planning.
As ever, we continue our environmental monitoring of conditions, with Mastcam and Navcam movies and images looking at dust in the atmosphere above and around us in Gale crater, and watching out for dust devils.
