Preparations for Next Moonwalk Simulations Underway (and Underwater)
Piloted by NASA’s Tim Williams, the ER-2 science aircraft ascends for one of the final science flights for the GSFC Lidar Observation and Validation Experiment (GLOVE) on Feb. 1, 2025. As a collaboration between engineers, scientists, and aircraft professionals, GLOVE aims to improve satellite data products for Earth Science applications. NASA/Steve Freeman In February, NASA’s ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is exploring how instruments analyzing clouds can improve data measurement methods.
Researchers participating in the Goddard Space Flight Center Lidar Observation and Validation Experiment (GLOVE) used the ER-2 – based at NASA’s Armstrong Flight Research Center in Edwards, California – to validate satellite data about cloud and airborne particles in the Earth’s atmosphere. Scientists are using GLOVE instruments installed onboard the aircraft to measure and validate data about clouds generated by satellite sensors already orbiting in space around Earth.
“The GLOVE data will allow us to test new artificial intelligence algorithms in data processing,” said John Yorks, principal investigator for GLOVE and research physical scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “These algorithms aim to improve the cloud and aerosol detection in data produced by the satellites.”

The Roscoe instrument will be uploaded onto NASA’s ER-2 science aircraft.NASA/Steve Freeman The validation provided by GLOVE is crucial because it ensures the accuracy and reliability of satellite data. “The instruments on the plane provide a higher resolution measurement ‘truth’ to ensure the data is a true representation of the atmospheric scene being sampled,” Yorks said.
The ER-2 flew over various parts of Oregon, Arizona, Utah, and Nevada, as well as over the Pacific Ocean off the coast of California. These regions reflected various types of atmospheres, including cirrus clouds, marine stratocumulus, rain and snow, and areas with multiple types of clouds.
“The goal is to improve satellite data products for Earth science applications,” Yorks said. “These measurements allow scientists and decision-makers to confidently use this satellite information for applications like weather forecasting and hazard monitoring.”

The GLOVE instrument will validate data from satellites orbiting the Earth.NASA/Steve Freeman The four instruments installed on the ER-2 were the Cloud Physics Lidar, the Roscoe Lidar, the enhanced Moderate Resolution Imaging Spectroradiometer Airborne Simulator, and the Cloud Radar System. These instruments validate data produced by sensors on NASA’s Ice, Cloud, and Land Elevation Satellite 2 (ICESat-2) and the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE), a joint venture between the ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency).
“Additionally, the EarthCARE satellite is flying the first ever Doppler radar for measurements of air motions within clouds,” Yorks said. While the ER-2 is operated by pilots and aircrew from NASA Armstrong, these instruments are supported by scientists from NASA Goddard, NASA’s Ames Research Center in California’s Silicon Valley, and the Naval Research Laboratory office in Monterey, California, as well as by students from the University of Iowa in Iowa City and the University of Maryland College Park.

NASA NASA astronauts Jim Lovell, Fred Haise, and Jack Swigert launch aboard the Apollo 13 spacecraft from NASA’s Kennedy Space Center in Florida on April 11, 1970. The mission seemed to be going smoothly until 55 hours and 55 minutes in when an oxygen tank ruptured. The new mission plan involved abandoning the Moon landing, looping around the Moon and getting the crew home safely as quickly as possible. The crew needed to go into “lifeboat mode,” using the lunar module Aquarius to save the spacecraft and crew. On April 17, the crew returned to Earth, splashing down in the Pacific Ocean near Samoa.

NASA Deep Space Station 43 (DSS-43), a 230-foot-wide (70-meter-wide) radio antenna at NASA’s Deep Space Network facility in Canberra, Australia, is seen in this March 4, 2020, image. DSS-43 was more than six times as sensitive as the original antenna at the Canberra complex, so it could communicate with spacecraft at greater distances from Earth. In fact, Canberra is the only complex that can send commands to, and receive data from, Voyager 2 as it heads south almost 13 billion miles (21 billion kilometers) through interstellar space. More than 15 billion miles (24 billion kilometers) away, Voyager 1 sends its data down to the Madrid and Goldstone complexes, but it, too, can only receive commands via Canberra.
As the Canberra facility celebrated its 60th anniversary on March 19, 2025, work began on a new radio antenna. Canberra’s newest addition, Deep Space Station 33, will be a 112-foot-wide (34-meter-wide) multifrequency beam-waveguide antenna. Buried mostly below ground, a massive concrete pedestal will house cutting-edge electronics and receivers in a climate-controlled room and provide a sturdy base for the reflector dish, which will rotate during operations on a steel platform called an alidade.
When it goes online in 2029, the new Canberra dish will be the last of six parabolic dishes constructed under NASA’s Deep Space Network Aperture Enhancement Program, which is helping to support current and future spacecraft and the increased volume of data they provide. The network’s Madrid facility christened a new dish in 2022, and the Goldstone, California, facility is putting the finishing touches on a new antenna.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The radio antennas of NASA’s Canberra Deep Space Communications Complex are lo-cated near the Australian capital. It’s one of three Deep Space Network facilities around the world that keep the agency in contact with dozens of space missions Located at Tidbinbilla Nature Reserve near the Australian capital city, the Canberra complex joined the Deep Space Network on March 19, 1965, with one 85-foot-wide (26-meter-wide) radio antenna. The dish, called Deep Space Station 42, was decommis-sioned in 2000. This photograph shows the facility in 1965.NASA Canberra joined the global network in 1965 and operates four radio antennas. Now, preparations have begun on its fifth as NASA works to increase the network’s capacity.
NASA’s Deep Space Network facility in Canberra, Australia celebrated its 60th anniversary on March 19 while also breaking ground on a new radio antenna. The pair of achievements are major milestones for the network, which communicates with spacecraft all over the solar system using giant dish antennas located at three complexes around the globe.
Canberra’s newest addition, Deep Space Station 33, will be a 112-foot-wide (34-meter-wide) multifrequency beam-waveguide antenna. Buried mostly below ground, a massive concrete pedestal will house cutting-edge electronics and receivers in a climate-controlled room and provide a sturdy base for the reflector dish, which will rotate during operations on a steel platform called an alidade.
Suzanne Dodd, the director for the Interplanetary Network Directorate at JPL, addresses an audience at the Deep Space Network’s Canberra complex on March 19, 2025. That day marked 60 years since the Australian facility joined the network.NASA “As we look back on 60 years of incredible accomplishments at Canberra, the groundbreaking of a new antenna is a symbol for the next 60 years of scientific discovery,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) Program at NASA Headquarters in Washington. “Building cutting-edge antennas is also a symbol of how the Deep Space Network embraces new technologies to enable the exploration of a growing fleet of space missions.”
When it goes online in 2029, the new Canberra dish will be the last of six parabolic dishes constructed under NASA’s Deep Space Network Aperture Enhancement Program, which is helping to support current and future spacecraft and the increased volume of data they provide. The network’s Madrid facility christened a new dish in 2022, and the Goldstone, California, facility is putting the finishing touches on a new antenna.
Canberra’s Role
The Deep Space Network was officially founded on Dec. 24, 1963, when NASA’s early ground stations, including Goldstone, were connected to the new network control center at the agency’s Jet Propulsion Laboratory in Southern California. Called the Space Flight Operations Facility, that building remains the center through which data from the three global complexes flows.
The Madrid facility joined in 1964, and Canberra went online in 1965, going on to help support hundreds of missions, including the Apollo Moon landings.
Three eye-catching posters featuring the larger 230-foot (70-meter) antennas located at the three Deep Space Network complexes around the world.NASA/JPL-Caltech “Canberra has played a crucial part in tracking, communicating, and collecting data from some of the most momentous missions in space history,” said Kevin Ferguson, director of the Canberra Deep Space Communication Complex. “As the network continues to advance and grow, Canberra will continue to play a key role in supporting humanity’s exploration of the cosmos.”
By being spaced equidistant from one another around the globe, the complexes can provide continual coverage of spacecraft, no matter where they are in the solar system as Earth rotates. There is an exception, however: Due to Canberra’s location in the Southern Hemisphere, it is the only one that can send commands to, and receive data from, Voyager 2 as it heads south almost 13 billion miles (21 billion kilometers) through interstellar space. More than 15 billion miles (24 billion kilometers) away, Voyager 1 sends its data down to the Madrid and Goldstone complexes, but it, too, can only receive commands via Canberra.
New Technologies
In addition to constructing more antennas like Canberra’s Deep Space Station 33, NASA is looking to the future by also experimenting with laser, or optical, communications to enable significantly more data to flow to and from Earth. The Deep Space Network currently relies on radio frequencies to communicate, but laser operates at a higher frequency, allowing more data to be transmitted.
As part of that effort, NASA is flying the laser-based Deep Space Optical Communications experiment with the agency’s Psyche mission. Since the October 2023 launch, it has demonstrated high data rates over record-breaking distances and downlinked ultra-high definition streaming video from deep space.
“These new technologies have the potential to boost the science and exploration returns of missions traveling throughout the solar system,” said Amy Smith, deputy project manager for the Deep Space Networkat JPL, which manages the network. “Laser and radio communications could even be combined to build hybrid antennas, or dishes that can communicate using both radio and optical frequencies at the same time. That could be a game changer for NASA.”
