Many team members at NASA’s Johnson Space Center in Houston may recognize Alicia Baker as the talented flutist in the Hispanic Employee Resource Group’s Mariachi Celestial band. Or, they may have worked with Baker in her role as a spacesuit project manager, testing NASA’s prototype spacesuits and preparing Johnson’s test chambers to evaluate vendor spacesuits.

“It was hard taking care of a loved one with cancer and working full-time,” Baker said. “My husband was also disabled from a brain tumor surgery, so I had to help him with reading, writing, walking, and remembering, while managing the household.”
Baker worked closely with her manager to coordinate schedules and get approval to telework so that she could work around her husband’s medical appointments and procedures. She also took medical leave when her husband entered hospice care in 2020. Baker said her manager’s flexibility “saved her job” and allowed her to continue providing for her family. She was even able to advance from project engineer to test director to project manager during this time period.

These caregivers provide help to a person in need who often has a medical condition or injury that affects their daily functioning. Their needs may be temporary or long-term, and they could be physical, medical, financial, or domestic in nature.
Recognizing the challenging and critical role caregivers play in their families, the Johnson community provides a variety of resources to support team members through the Employee Assistance Program. Additionally, Johnson’s No Boundaries Employee Resource Group (NoBo) supports caregivers through its programs and initiatives.
Baker participates in both the support group and NoBo activities and takes comfort in sharing her and her husband’s story with others. “I would do it all over again,” she said of her caregiver role.
Now she looks forward to future missions to the Moon, when NASA astronauts will conduct spacewalks on the lunar surface while wearing new spacesuits. “Then I can say I helped make that possible!” Throughout all of her experiences, Baker has learned to never give up. “If you have a dream, keep fighting for it,” she said.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Coastal locations, such as Drakes Bay on the Point Reyes peninsula in Northern California, are increasingly vulnerable to sea level rise.NOAA/NMFS/WCR/CCO The information will help people who live in coastal areas prepare for impacts caused by rising sea levels.
Earth’s ocean is rising, disrupting livelihoods and infrastructure in coastal communities around the world. Agencies and organizations are working to prepare people as their world changes around them, and NASA information is helping these efforts.
The agency’s global data is now available in the sea level section of the Earth Information Center. NASA developed the global sea level change website in collaboration with the U.S. Department of Defense, the World Bank, the U.S. Department of State, and the United Nations Development Programme.
The site includes information on projected sea level rise through the year 2150 for coastlines around the world, as well as estimates of how much flooding a coastal community or region can expect to see in the next 30 years. The projections come from data collected by NASA and its partners and from computer models of ice sheets and the ocean, as well as the latest sea level assessment from the Intergovernmental Panel on Climate Change, and other sources.
“NASA innovates for the benefit of humanity. Our cutting-edge instruments and data-driven information tools help communities and organizations respond to natural hazards and extreme weather, and inform critical coastal infrastructure planning decisions,” said Karen St. Germain, director of the Earth science division at NASA Headquarters in Washington.
Information to Action
International organizations such as the World Bank will use the data from the global sea level change site for tasks including the creation of Climate Risk Profiles for countries especially vulnerable to sea level rise.
The Defense Department will continue to incorporate sea level rise data into its plans to anticipate and respond to hazards posed to its facilities by the effects of rising oceans. Similarly, the State Department uses the information for activities ranging from disaster preparedness to long-term adaptation planning to supporting partners around the world in related efforts.
“We are at a moment of truth in our fight against the climate crisis. The science is unequivocal and must serve as the bedrock upon which decision-making is built. With many communities around the world already facing severe impacts from sea-level rise, this new resource provides a vital tool to help them protect lives and livelihoods. It also illustrates what is at stake between a 1.5-degree-Celsius world and a current-policies trajectory for all coastal communities worldwide,” said Assistant Secretary-General Selwin Hart, special adviser to the United Nations secretary-general on climate action and just transition.
Rising Faster
NASA-led data analyses have revealed that between 1970 and 2023, 96% of countries with coastlines have experienced sea level rise. The rate of that global rise has also accelerated, more than doubling from 0.08 inches (0.21 centimeters) per year in 1993 to about 0.18 inches (0.45 centimeters) per year in 2023.
As the rate of sea level rise increases, millions of people could face the related effects sooner than previously projected, including larger storm surges, more saltwater intrusion into groundwater, and additional high-tide flood days — also known as nuisance floods or sunny day floods.
“This new platform shows the timing of future floods and the magnitude of rising waters in all coastal countries worldwide, connecting science and physics to impacts on people’s livelihoods and safety,” said Nadya Vinogradova Shiffer, director of the ocean physics program at NASA Headquarters in Washington.
Data released earlier this year found that Pacific Island nations will experience at least 6 inches (15 centimeters) of sea level rise in the next 30 years. The number of high-tide flood days will increase by an order of magnitude for nearly all Pacific Island nations by the 2050s.
“The data is clear: Sea levels are rising around the world, and they’re rising faster and faster,” said Ben Hamlington, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and head of the agency’s sea level change science team. “Having the best information to make decisions about how to plan for rising seas is more crucial than ever.”

An artist’s rendering of NASA’s Gateway space station in lunar orbit, featuring the Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO), left, and a photograph of an antenna undergoing testing in an anechoic chamber at NASA’s Johnson Space Center, right.NASA/Robert Markowitz Engineers at NASA’s Johnson Space Center recently began electric field testing on representative communications hardware for Gateway, humanity’s first space station to orbit the Moon.
An orbiting laboratory for deep space science and a staging ground for lunar exploration, Gateway will help NASA and its international partners establish a sustained human presence on and around the Moon in preparation for the next giant leap – human exploration of Mars.
High-gain antennas are an important component of Gateway’s communication and tracking system that connects operations across the vast distances of the lunar South Pole region, to Gateway in orbit around the Moon, to Earth, and back again.
NASA is conducting rigorous testing on the electric field levels radiated by the antennas to ensure safe and efficient communication and to avoid any interference with Gateway’s crew and equipment. By validating simulation models to accurately predict electric field levels, NASA can establish precise safety zones around the K/Ka-band parabolic reflector antennas to protect astronauts and hardware without sacrificing high-rate communications.
During the meticulous testing process, engineers use electric field and waveguide probes, which measure the strength and quality of electromagnetic signals, to scan the near fields of a representative high-gain antenna. Robotic arms and optical tracking systems provide the precise measurements needed for model validation. The testing is being conducted in an anechoic chamber, a specialized room that provides a controlled environment for measurements of electromagnetic waves.
“We are sharpening our pencil in conducting model validation measurements – ensuring high accuracy in the analysis of electric fields radiated by the high-gain antennas on Gateway,” said Timothy Kennedy, one of the NASA engineers overseeing the tests. “This enables reduced margins on antenna masking needed to protect equipment and crew, while maximizing communication coverage.”
Findings are expected to enhance NASA’s understanding of the electric field levels emitted by Gateway’s antennas and inform critical decisions for operating them safely during Artemis missions, ensuring that Gateway is a safe home for astronauts around the Moon.
