NASA Stennis Plants Artemis Moon Tree

A tree-planting ceremony at NASA’s Stennis Space Center on Oct. 29 celebrated NASA’s successful Artemis I mission as the agency prepares for a return around the Moon with astronauts on Artemis II.

“We already have a thriving Moon Tree from the Apollo years onsite,” NASA Stennis Director John Bailey said. “It is exciting to add trees for our new Artemis Generation as it continues the next great era of human space exploration.”

NASA’s Office of STEM Engagement Next Gen STEM Project partnered with U.S. Department of Agriculture (USDA) Forest Service to fly five species of tree seeds aboard the Orion spacecraft during the successful uncrewed Artemis I test flight in 2022 as part of a national STEM Engagement and conservation education initiative. 

The Artemis Moon Tree species included sweetgums, loblolly pines, sycamores, Douglas-firs, and giant sequoias. The seeds from the first Artemis mission have been nurtured by the USDA into seedlings to be a source of inspiration for the Artemis Generation.

The Moon Tree education initiative is rooted in the legacy of Apollo 14 Moon Tree seeds flown in lunar orbit over 50 years ago by the late Stuart Roosa, a NASA astronaut and Mississippi Coast resident.

NASA Stennis and the NASA Shared Services Center (NSSC), located at the site, planted companion trees during the Oct. 29 ceremony. Bailey and NSSC Executive Director Anita Harrell participated in a joint planting ceremony attended by a number of employees from each entity.

The American sweetgum trees are the second and third Moon Trees at the south Mississippi site. In 2004, ASTRO CAMP participants planted a sycamore Moon Tree to honor the 35^th anniversary of Apollo 11 and the first lunar landing on July 20, 1969.

The road to space for both Apollo 14 and Artemis I went through Mississippi. Until 1970, NASA Stennis test fired first, and second stages of the Saturn V rockets used for Apollo.

NASA Stennis now tests all the RS-25 engines powering Artemis missions to the Moon and beyond. Prior to Artemis I, NASA Stennis tested the SLS (Space Launch System) core stage and its four RS-25 engines.

The Artemis Moon Trees have found new homes in over 150 communities and counting since last spring, and each of the 10 NASA centers also will plant one.

As the tree grows at NASA Stennis, so, too, does anticipation for the first crewed mission with Artemis II. Four astronauts will venture around the Moon on NASA’s path to establishing a long-term presence at the Moon for science and exploration.

The flight will test NASA’s foundational human deep space exploration capabilities – the SLS rocket and Orion spacecraft – for the first time with astronauts.

Bioprinted patches could help wounds heal

Researchers successfully demonstrated the function of a handheld bioprinter that could provide a simple and effective way to treat wounds in space using human skin cells. Crews could use this technology to treat their own injuries and protect crew health and mission success in the future.

Spaceflight can affect how wounds heal. The Bioprint FirstAid device tested a process for bioprinting a patch to cover a wound and accelerate healing. In the future, a crew member’s own cells may be used to create personalized patches for treating an injury. The bioprinting device is easy to use, can be tailored to specific needs, has a low failure rate, and its mechanics are electronics- and maintenance-free. This ESA (European Space Agency) investigation was coordinated by the German Aerospace Center (DLR).

Countering post-flight proficiency challenges

The day they return from spaceflight, astronauts demonstrate significant impairments in fine motor control and the ability to multitask in simulated flying and driving challenges. This finding could help develop countermeasures so crew members can safely land and conduct early operations on the Moon and Mars.

Manual Control used a battery of tests to examine how spaceflight affects cognitive, sensory, and motor function after landing. Researchers concluded that subtle physiological changes that occur during spaceflight degrade post-flight performance. Subsequent tests showed recovery of performance once exposed to the task, suggesting that simulation training immediately before a task could be an effective countermeasure. Researchers also suggest limiting dual or competing tasks during mission-critical phases.

Gamma-ray telescope resilient to space radiation

Researchers found that the station’s Glowbug gamma-ray telescope could perform in the space radiation environment for multi-year missions. Radiation can affect these types of instruments, but Glowbug regularly detected gamma ray bursts (GRBs) during its one-year operation. Studying GRBs can help scientists better understand the universe and its origins.

Glowbug demonstrated technology to detect and characterize cosmic GRBs, primarily short GRBs, which result from mergers of compact binary star systems containing either two neutron stars or a neutron star and a black hole. Short GRBs produce gravitational waves, ripples in space that travel at the speed of light. Studying these gravitational waves could provide insight into the star systems where they originate and the behavior of matter during the mergers.

Still Kickin’ Since the ’70s: NASA’s Voyager Mission Keeps Exploring

NASA’s Voyager mission launched in the 1970s. Today, it’s making history as it conducts new science. But how are two spacecraft from the ’70s not just surviving, but thriving farther out in space than any other spacecraft has been before?

A Little Mission Background

Voyager is a NASA mission made up of two different spacecraft, Voyager 1 and 2, which launched to space on Sept. 5, 1977, and Aug. 20, 1977, respectively. In the decades following launch, the pair took a grand tour of our solar system, studying Jupiter, Saturn, Uranus, and Neptune — one of NASA’s earliest efforts to explore the secrets of the universe. These twin probes later became the first spacecraft to operate in interstellar space — space outside the heliosphere, the bubble of solar wind and magnetic fields emanating from the Sun. Voyager 1 was the first to enter interstellar space in 2012, followed by Voyager 2 in 2018.  

Today, Voyager continues not just because it can, but because it still has work to do studying interstellar space, the heliosphere, and how the two interact. “We wouldn’t be doing Voyager if it wasn’t taking science data,” said Suzanne Dodd, the mission’s current project manager and the director for the Interplanetary Network at NASA’s Jet Propulsion Laboratory.

But across billions of miles and decades of groundbreaking scientific exploration, this trailblazing interstellar journey has not been without its trials. So, what’s the Voyager secret to success? 

In short: preparation and creativity.  

We Designed Them Not to Fail

According to John Casani, Voyager project manager from 1975 to launch in 1977, “we didn’t design them to last 30 years or 40 years, we designed them not to fail.”

One key driver of the mission’s longevity is redundancy. Voyager’s components weren’t just engineered with care, they were also made in duplicate. 

According to Dodd, Voyager “was designed with nearly everything redundant. Having two spacecraft — right there is a redundancy.” 

“We didn’t design them to last 30 years or 40 years, we designed them not to fail.”

A Cutting-Edge Power Source

The twin Voyager spacecraft can also credit their longevity to their long-lasting power source. 

Each spacecraft is equipped with three radioisotope thermoelectric generators. These nuclear “batteries” were developed originally by the U.S. Department of Energy as part of the Atoms for Peace program enacted by President Eisenhower in 1955. Compared to other power options at the time — like solar power, which doesn’t have the reach to work beyond Jupiter — these generators have allowed Voyager to go much farther into space. 

Voyager’s generators continue to take the mission farther than any before, but they also continue to generate less power each year, with instruments needing to be shut off over time to conserve power. 

Creative Solutions  

As a mission that has operated at the farthest edges of the heliosphere and beyond, Voyager has endured its fair share of challenges. With the spacecraft now in interstellar space running on software and hardware from the 1970s, Voyager’s problems require creative solutions.  

Retired mission personnel who worked on Voyager in its earliest days have even come back out of retirement to collaborate with new mission personnel to not just fix big problems but to pass on important mission know-how to the next generation of scientists and engineers.

“From where I sit as a project manager, it’s really very exciting to see young engineers be excited to work on Voyager. To take on the challenges of an old mission and to work side by side with some of the masters, the people that built the spacecraft,” Dodd said. “They want to learn from each other.” 

Within just the last couple of years, Voyager has tested the mission team’s creativity with a number of complex issues. Most recently, the thrusters on Voyager 1’s thrusters, which control the spacecraft’s orientation and direction, became clogged. The thrusters allow the spacecraft to point their antennae and are critical to maintaining communications with Earth. Through careful coordination, the mission team was able to remotely switch the spacecraft to a different set of thrusters. 

These kinds of repairs are extra challenging as a radio signal takes about 22 ½ hours to reach Voyager 1 from Earth and another 22 ½ hours to return. Signals to and from Voyager 2 take about 19 hours each way.

Voyager’s Interstellar Future

This brief peek behind the curtain highlights some of Voyager’s history and its secrets to success. 

The Voyager probes may continue to operate into the late 2020s. As time goes on, continued operations will become more challenging as the mission’s power diminishes by 4 watts every year, and the two spacecraft will cool down as this power decreases. Additionally, unexpected anomalies could impact the mission’s functionality and longevity as they grow older.

As the mission presses on, the Voyager team grows this legacy of creative problem solving and collaboration while these twin interstellar travelers continue to expand our understanding of the vast and mysterious cosmos we inhabit.

NASA, Bhutan Conclude Five Years of Teamwork on STEM, Sustainability

NASA and the Kingdom of Bhutan have been actively learning from each other and growing together since 2019. The seeds planted over those years have ripened into improved environmental conservation, community-based natural resource management, and new remote sensing tools.

Known for its governing philosophy of “gross national happiness,” [Bhutan] has a constitutional mandate to maintain at least 60% forest cover. The government’s goals include achieving nationwide food security by 2030. 

Bhutan first approached the U.S. State Department to partner on science, technology, engineering, and mathematics (STEM) opportunities for the country, and NASA was invited to help lead these opportunities. In 2019, Bhutan’s King Jigme Khesar Namgyel Wangchuck visited NASA’s Ames Research Center in Silicon Valley, California, and was introduced to several NASA programs.

NASA’s Earth scientists and research staff from several complementary programs have helped support Bhutan’s goals by providing data resources and training to make satellite data more useful to communities and decision makers. Bhutan now uses NASA satellite data in its national land management decisions and plans to foster more geospatial jobs to help address environmental issues.

Supporting Bhutan’s Environmental Decision Makers

Bhutan’s National Land Commission offers tax breaks to farmers to support food security and economic resilience. However, finding and reaching eligible farmers on the ground can be expensive and time consuming, which means small farmers in remote areas can be missed. 

A team from SERVIR – a joint NASA-U.S. Agency for International Development initiative – worked with Bhutanese experts to create decision-making tools like the Farm Action Toolkit  (FAcT). The tool uses imagery from the NASA-U.S. Geological Survey Landsat satellites to identify and measure the country’s farmland. SERVIR researchers met with agricultural organizations – including Bhutan’s Ministry of Agriculture and Livestock, National Statistics Bureau, and National Center for Organic Agriculture – to adjust the tool for the country’s unique geography and farming practices. The Land Commission now uses FAcT to identify small farms and bring support to more of the country. 

NASA also develops local capacity to use Earth data through efforts like the Applied Remote Sensing Training Program (ARSET). In early 2024, ARSET staff worked with SERVIR and Druk Holdings and Investments (DHI) to host a workshop with 46 Bhutanese government personnel. Using tailored local case studies, the teams worked to find ways to better manage natural resources, assist land use planning, and monitor disasters. 

“We look forward to continuing this collaboration, as there are still many areas where NASA’s expertise can significantly impact Bhutan’s development goals,” said Manish Rai, an analyst with DHI who helped coordinate the workshop. “This collaboration is a two-way street. While Bhutan has benefited greatly from NASA’s support, we believe there are also unique insights and experiences that Bhutan can share with NASA, particularly in areas like environmental conservation and community-based natural resource management.” 

Encouraging Bhutan’s Future Environmental Leaders

By working with students and educators from primary schools to the university level, Bhutan and NASA have been investing in the country’s future environmental leadership. Supporting educators and “training trainers” have been pillars of this collaboration.

NASA and Bhutan have worked together to boost the skills of early-career Earth scientists. For example, NASA’s DEVELOP program for undergraduates worked directly with local institutions to create several applied science internships for Bhutanese students studying in the U.S. 

Tenzin Wangmo, a high school biology teacher in Bhutan, participated in DEVELOP projects focusing on agriculture and water resources. According to Wangmo, the lessons learned from those projects have been helpful in connecting with her students about STEM opportunities and environmental issues. “Most people only think of NASA as going to space, rather than Earth science,” she said. “It was encouraging to my students that there are lots of opportunities for you if you try.”

NASA is also supporting Bhutan’s future environmental leadership through the GLOBE (Global Learning and Observations to Benefit the Environment) Program. The GLOBE program is a U.S. interagency outreach program that works with teachers to support STEM literacy through hands-on environmental learning. Since 2020, GLOBE has worked through the U.S. State Department and organizations like the Ugyen Wangchuck Institute for Forest Research and Training to support educators at two dozen schools in Bhutan. The program reached more than 650 students with activities like estimating their school’s carbon footprint. 

This focus on STEM education enables students and professionals to contribute to Bhutan’s specific development goals now and in the future. 

Sonam Tshering, a student who completed two DEVELOP projects on Bhutanese agriculture while studying at the University of Texas at El Paso, was able to share the value of these efforts at the 2023 United Nations Climate Conference. “By applying satellite data from NASA, we aimed to create actionable insights for our local farmers and our policymakers back in Bhutan,” she said.
