Preparations for Next Moonwalk Simulations Underway (and Underwater)
A crane lowers the steel reflector framework for Deep Space Station 23 into position Dec. 18 on a 65-foot-high (20-meter) platform above the antenna’s pedestal that will steer the reflector. Panels will be affixed to the structure create a curved surface to collect radio frequency signals.NASA/JPL-Caltech After the steel framework of the Deep Space Station 23 reflector dish was lowered into place on Dec. 18, a crew installed the quadripod, a four-legged support structure that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna’s receiver.NASA/JPL-Caltech Deep Space Station 23’s 133-ton reflector dish was recently installed, marking a key step in strengthening NASA’s Deep Space Network.
NASA’s Deep Space Network, an array of giant radio antennas, allows agency missions to track, send commands to, and receive scientific data from spacecraft venturing to the Moon and beyond. NASA is adding a new antenna, bringing the total to 15, to support increased demand for the world’s largest and most sensitive radio frequency telecommunication system.
Installation of the latest antenna took place on Dec. 18, when teams at NASA’s Goldstone Deep Space Communications Complex near Barstow, California, installed the metal reflector framework for Deep Space Station 23, a multifrequency beam-waveguide antenna. When operational in 2026, Deep Space Station 23 will receive transmissions from missions such as Perseverance, Psyche, Europa Clipper, Voyager 1, and a growing fleet of future human and robotic spacecraft in deep space.
“This addition to the Deep Space Network represents a crucial communication upgrade for the agency,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) program. “The communications infrastructure has been in continuous operation since its creation in 1963, and with this upgrade we are ensuring NASA is ready to support the growing number of missions exploring the Moon, Mars, and beyond.”
This time-lapse video shows the entire day of construction activities for the Deep Space Station 23 antenna at the NASA Deep Space Network’s Goldstone Space Communications Complex near Barstow, California, on Dec. 18. NASA/JPL-Caltech Construction of the new antenna has been under way for more than four years, and during the installation, teams used a crawler crane to lower the 133-ton metal skeleton of the 112-foot-wide (34-meter-wide) parabolic reflector before it was bolted to a 65-foot-high (20-meter-high) alidade, a platform above the antenna’s pedestal that will steer the reflector during operations.
“One of the biggest challenges facing us during the lift was to ensure that 40 bolt-holes were perfectly aligned between the structure and alidade,” said Germaine Aziz, systems engineer, Deep Space Network Aperture Enhancement Program of NASA’s Jet Propulsion Laboratory in Southern California. “This required a meticulous emphasis on alignment prior to the lift to guarantee everything went smoothly on the day.”
Following the main lift, engineers carried out a lighter lift to place a quadripod, a four-legged support structure weighing 16 1/2 tons, onto the center of the upward-facing reflector. The quadripod features a curved subreflector that will direct radio frequency signals from deep space that bounce off the main reflector into the antenna’s pedestal, where the antenna’s receivers are housed.
In the early morning of Dec. 18, a crane looms over the 112-foot-wide (34-meter-wide) steel framework for Deep Space Station 23 reflector dish, which will soon be lowered into position on the antenna’s base structure.NASA/JPL-Caltech Engineers will now work to fit panels onto the steel skeleton to create a curved surface to reflect radio frequency signals. Once complete, Deep Space Station 23 will be the fifth of six new beam-waveguide antennas to join the network, following Deep Space Station 53, which was added at the Deep Space Network’s Madrid complex in 2022.
“With the Deep Space Network, we are able to explore the Martian landscape with our rovers, see the James Webb Space Telescope’s stunning cosmic observations, and so much more,” said Laurie Leshin, director of JPL. “The network enables over 40 deep space missions, including the farthest human-made objects in the universe, Voyager 1 and 2. With upgrades like these, the network will continue to support humanity’s exploration of our solar system and beyond, enabling groundbreaking science and discovery far into the future.”
NASA’s Deep Space Network is managed by JPL, with the oversight of NASA’s SCaN Program. More than 100 NASA and non-NASA missions rely on the Deep Space Network and Near Space Network, including supporting astronauts aboard the International Space Station and future Artemis missions, monitoring Earth’s weather and the effects of climate change, supporting lunar exploration, and uncovering the solar system and beyond.

NASA astronaut and Expedition 72 Commander Suni Williams checks out the Astrobee robotic free-flyer in the Kibo laboratory module outfitted with tentacle-like arms containing gecko-like adhesive pads to demonstrate satellite capture techniques. Development of this robotic technology may increase the life span of satellites and enable the removal of space debris.NASA In this picture from Nov. 15, 2024, Astronaut Suni Williams imitates the tentacle-like arms of the Astrobee robotic free-flyer in the foreground.
Astrobee robots help astronauts reduce time they spend on routine duties, leaving them to focus more on the things that only humans can do. Working autonomously or via remote control by astronauts, flight controllers or researchers on the ground, the robots are designed to complete tasks such as taking inventory, documenting experiments conducted by astronauts with their built-in cameras or working together to move cargo throughout the station. In addition, the system serves as a research platform that can be outfitted and programmed to carry out experiments in microgravity – helping us to learn more about how robotics can benefit astronauts in space.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Research scientist Alfonso Delgado Bonal makes important discoveries about patterns in cloud movements while thriving within the NASA Goddard family.
Name: Alfonso Delgado Bonal
Formal Job Classification: Research scientist
Organization: Climate and Radiation Laboratory, Science Directorate (Code 613)
Alfonso Delgado Bonal is a research scientist for NASA’s Goddard Space Flight Center’s Climate and Radiation Laboratory in Greenbelt, Md.NASA What do you do and what is most interesting about your role here at Goddard?
As a theoretical physicist, I study data from the DSCOVR satellite to analyze daytime variability of cloud properties. We are discovering diurnal (daylight) cloud patterns using a single sensor.
What is your educational background?
I have an undergraduate degree in theoretical physics from the University of Salamanca, Spain. I have a master’s in astrophysics from the University of Valencia, Spain, and a second master’s in space technology from the University of Alcalá, Spain. In 2015, I received a doctorate in theoretical physics from the University of Salamanca.
From 2016–2018, I had a postdoctoral fellowship with the Spanish National Research Agency. From 2018–2020, I had a postdoctoral fellowship at Goddard’s Climate and Radiation Laboratory.
I also have an undergraduate degree in economics from the Spanish Open University and an undergraduate degree in law from the University of La Rioja, Spain. I am considering returning to school for a master’s in law to sit for the bar.
What fascinates you about clouds?
As a child, I remember watching clouds moving. I never questioned whether these clouds moved randomly or in a pattern. One day, Sasha Marshak, my supervisor and one of my mentors, asked me to determine if clouds move randomly or in a pattern.
Clouds have a profound impact on our planet. They regulate the Earth’s energy budget. Some clouds reflect radiation that cools our planet while other clouds trap radiation which warms our planet. Cloud behavior is one of the most important factors in regulating climate change.
What is the data from the DSCOVR satellite telling you?
DSCOVR is the only satellite capturing data that shows the entire sunlit part of the Earth at once. The left part of an image is early morning and the right part of an image is nearing sunset. For the first time, we can see how clouds evolve throughout the entire day. Other satellites only capture either a fixed time or a small region of the planet.
We discovered that clouds do not move randomly, they move in patterns. We measure these patterns in terms of cloud fraction (the amount of sky covered by clouds), cloud height and cloud optical thickness. In general, at noon we have the maximum cloud coverage over land and the minimum cloud coverage over sea. Also, at noon, clouds are generally lower and thicker. There is some predictability in the general pattern of cloud movement.
Coming from Spain, what was the most unusual cultural aspect you had to adjust to when you joined your lab?
When I arrived from Spain, my English was not great and I did not understand the cultural aspects. My first email was from Headquarters thanking the whole NASA family. The idea of a work family was something unfamiliar. To me, family meant blood relatives.
After one or two years, I felt that members of my lab were indeed my family. They really care about me as a person and I feel the same about them. We have parties where we do not talk about work, we talk about ourselves and our families. Our lab has people from all over the world, and we all share the same feeling about being part of the NASA family. We have a family at home and also a family at NASA.
Every time I see Sasha, he always asks about my family and about myself before talking about the work. Lazaros Oreopoulos, Sasha’s supervisor, does the same. They really inspire me.
As your mentors, how did Sasha and Lazaros made you feel welcome?
I came here from a different world. I was doing theoretical physics in Spain but my NASA post doc involved data analysis, which is what I am doing now. Sasha also came from a different county and also had a strong mathematical background. I felt that he understood me and the challenges before me. He made me feel extremely welcome and explained some cultural aspects. He made sure that I understood how the lab worked, introduced me to everyone, and invited my wife and me to dinner at his home. He really made me feel part of the NASA family.
Lazaros strikes the perfect balance between being a respected supervisor and acting like family. He always has a winter party for the entire office where everyone brings in homemade food from their country. Our lab has people from many different countries. Lazaros always checks in with me to see how I am doing. He has created a marvelous place where we all feel like family and do great work.
Lazaros and Sasha gave me a chance when they invited me to join their lab. I do not have words to thank them enough for believing in me when I was just a post doc and for guiding me through my career and, most of all, for their incredible advice about life. They are now both family to me.
What advice have your mentors given you?
Both Sasha and Lazaros taught me creativity. They both always ask questions. Even if a question seems at first impossible to answer, eventually you will develop the tools to answer the questions. It was Sasha who asked me if clouds have random behavior or move in patterns. It has taken me a few years to answer his question and now we are making unexpected and important discoveries about clouds.
What do you do for fun?
Now that I have two young children, my fun now is spending as much time as I can with my wife and children. My wife is a biologist and I have learned a lot from her.
What book are you currently reading?
I love reading. I am rereading the “Iliad,” one of my favorites. My favorite book is “The Little Prince.” I read my children a bedtime story every night and now that they are a little older, sometimes they read one to me.
What is your one big dream?
To see my kids have great lives and be happy.
What is your motto?
“If you’re going to try, go all the way.” —Charles Bukowski
