For more than a decade, Tristan McKnight has been a driving force behind some of NASA’s most iconic events, orchestrating the behind-the-scenes magic that brings each historic moment to life while sharing the agency’s advancements with the public. 

As a multimedia producer on the audiovisual team at Johnson Space Center in Houston, McKnight produces and directs live broadcasts and manages event planning, coordination, and execution. From overseeing resources, mitigating risks, and communicating with stakeholders, he ensures every detail aligns seamlessly.  

McKnight has played an integral role in the audiovisual team’s coverage of major events including the Artemis II crew announcement, where NASA revealed the astronauts who will venture around the Moon and back, to Johnson’s 2023 Open House, which celebrated the agency’s 65th anniversary and the 25th anniversary of the International Space Station’s operations. These achievements highlight key milestones in human space exploration.  

A standout achievement was contributing to the Dorothy Vaughan Center in Honor of the Women of Apollo naming ceremony, held on the eve of the 55th anniversary of the Apollo 11 Moon landing. The event honored the unsung heroes who made humanity’s first steps on the Moon possible. 

The team’s dedication and passion are a testament to their commitment to sharing NASA’s legacy with the world. 

“Not only have these events been impactful to Johnson, but they have also resonated across the entire agency,” McKnight said. “That is what I’m most proud of!” 

One of McKnight’s most memorable events was the 2023 “Back in the Saddle,” an annual tradition designed to refocus Johnson’s workforce at the start of a new year and renew the center’s commitment to safety and mission excellence. McKnight recalled how the speaker transformed Johnson’s Teague Auditorium into a venue filled with drum kits, inspiring messages, and lighting displays. Each audience member, drumsticks in hand, participated in a lesson on teamwork and synchronization to create a metaphor for working in harmony toward a shared goal. 

Like many high-achieving professionals. McKnight has faced moments of self-doubt. Then he realized that he is exactly where he is supposed to be. “As I settled into my role, I recognized that my contributions matter and simply being true to who I am adds value to the Johnson community,” he said.  

Each day brings its own set of challenges, ranging from minor issues like communication gaps and scheduling conflicts to major obstacles like technology failures. One of McKnight’s most valuable lessons is recognizing that there is no one-size-fits-all solution, and each situation requires a thoughtful analysis. 

McKnight understands the importance of the “check-and double-check,” a philosophy he considers crucial when working with technology. “Taking the extra time to do your due diligence, or even having someone else take a look, can make all the difference,” he said. 

“The challenges I’ve faced helped me grow as a problem solver and taught me valuable lessons on resilience and adaptability in the workplace,” he said. McKnight approaches obstacles with a level head, focusing on effective solutions rather than dwelling on the problem. 

As humanity looks to the stars, McKnight is energized about the future of exploration, particularly advancements in spacesuit and rocket technology that will enable us to travel farther, faster, and safer than ever before. His work, though grounded on Earth, helps create the inspiration that fuels these bold endeavors. 

“My hope for the next generation is that they dive deeper into their curiosity—exploring not only the world around them but also the Moon, planets, and beyond,” he said. “I also hope they carry forward the spirit of resilience and a commitment to making the world a better place for all.” 

In Aug. 2024, a team of NASA researchers and partners gathered in Missoula, Montana to test new drone-based technology for localized forecasting, or micrometeorology. Researchers attached wind sensors to a drone, NASA’s Alta X quadcopter, aiming to provide precise and sustainable meteorological data to help predict fire behavior.

Wildfires are increasing in number and severity around the world, including the United States, and wind is a major factor. It leads to unexpected and unpredictable fire growth, public threats, and fire fatalities, making micrometeorology a very effective tool to combat fire.

The campaign was run by NASA’s FireSense project, focused on addressing challenges in wildland fire management by putting NASA science and technology in the hands of operational agencies.

“Ensuring that the new technology will be easily adoptable by operational agencies such as the U.S. Forest Service and the National Weather Service was another primary goal of the campaign,” said Jacquelyn Shuman, FireSense project scientist at NASA’s Ames Research Center in California’s Silicon Valley.

The FireSense team chose the Alta X drone because the U.S. Forest Service already has a fleet of the quadcopters and trained drone pilots, which could make integrating the needed sensors – and the accompanying infrastructure – much easier and more cost-effective for the agency.

The choice of the two sensors for the drone’s payload was also driven by their adoptability.

The first, called a radiosonde, measures wind direction and speed, humidity, temperature, and pressure, and is used daily by the National Weather Service. The other sensor, an anemometer, measures wind speed and direction, and is used at weather stations and airports around the world.

“Anemometers are everywhere, but are usually stationary,” said Robert McSwain, the FireSense uncrewed aerial system (UAS) lead, based at NASA’s Langley Research Center in Hampton, Virginia. “We are taking a sensor type that is already used all over the world, and giving it wings.”

Both sensors create datasets that are already familiar to meteorologists worldwide, which opens up the potential applications of the platform.

Current Forecasting Methods: Weather Balloons

Traditionally, global weather forecasting data is gathered by attaching a radiosonde to a weather balloon and releasing it into the air. This system works well for regional weather forecasts. But the rapidly changing environment of wildland fire requires more recurrent, pinpointed forecasts to accurately predict fire behavior. It’s the perfect niche for a drone.

“These drones are not meant to replace the weather balloons,” said Jennifer Fowler, FireSense’s project manager at Langley. “The goal is to create a drop-in solution to get more frequent, localized data for wildfires – not to replace all weather forecasting.”

Drones Provide Control, Repeat Testing, Sustainability

Drones can be piloted to keep making measurements over a precise location – an on-site forecaster could fly one every couple of hours as conditions change – and gather timely data to help determine how weather will impact the direction and speed of a fire.

Fire crews on the ground may need this information to make quick decisions about where to deploy firefighters and resources, draw fire lines, and protect nearby communities.

A reusable platform, like a drone, also reduces the financial and environmental impact of forecasting flights. 

“A weather balloon is going to be a one-off, and the attached sensor won’t be recovered,” Fowler said. “The instrumented drone, on the other hand, can be flown repeatedly.”

The Missoula Campaign

Before such technology can be sent out to a fire, it needs to be tested. That’s what the FireSense team did this summer.

McSwain described the conditions in Missoula as an “alignment of stars” for the research: the complex mountain terrain produces erratic, historically unpredictable winds, and the sparsity of monitoring instruments on the ground makes weather forecasting very difficult. During the three-day campaign, several fires burned nearby, which allowed researchers to test how the drones performed in smokey conditions.

A drone team out of NASA Langley conducted eight data-collection flights in Missoula. Before each drone flight, student teams from the University of Idaho in Moscow, Idaho, and Salish Kootenai College in Pablo, Montana, launched a weather balloon carrying the same type of radiometer.

Once those data sets were created, they needed to be transformed into a usable format. Meteorologists are used to the numbers, but incident commanders on an active fire need to see the data in a form that allows them to quickly understand which conditions are changing, and how. That’s where data visualization partners come in. For the Missoula campaign, teams from MITRE, NVIDIA, and Esri joined NASA in the field.

Measurements from both the balloon and the drone platforms were immediately sent to the on-site data teams. The MITRE team, together with NVIDIA, tested high-resolution artificial intelligence meteorological models, while the Esri team created comprehensive visualizations of flight paths, temperatures, and wind speed and direction. These visual representations of the data make conclusions more immediately apparent to non-meteorologists.

What’s Next?

Development of drone capabilities for fire monitoring didn’t begin in Missoula, and it won’t end there.

“This campaign leveraged almost a decade of research, development, engineering, and testing,” said McSwain. “We have built up a UAS flight capability that can now be used across NASA.”

The NASA Alta X and its sensor payload will head to Alabama and Florida in spring 2025, incorporating improvements identified in Montana. There, the team will perform another technology demonstration with wildland fire managers from a different region.

The FireSense project is led by NASA Headquarters in Washington and sits within the Wildland Fires program, with the project office based at NASA Ames. The goal of FireSense is to transition Earth science and technological capabilities to operational wildland fire management agencies, to address challenges in U.S. wildland fire management before, during, and after a fire. 

We’ve been talking about this for 2,000 years. Aristotle mentions it. And in our own time, scientists are designing experiments to figure out exactly what’s going on. But there’s no consensus yet.

Here’s what we do know.

The atmosphere isn’t magnifying the Moon. If anything, atmospheric refraction squashes it a little bit. And the Moon’s not closer to us at the horizon. It’s about 1.5 percent farther away. Also, it isn’t just the Moon. Constellations look huge on the horizon, too.

One popular idea is that this is a variation on the Ponzo illusion. Everything in our experience seems to shrink as it recedes toward the horizon — I mean clouds and planes and cars and ships. But the Moon doesn’t do that. So our minds make up a story to reconcile this inconsistency. Somehow the Moon gets bigger when it’s at the horizon. That’s one popular hypothesis, but there are others. And we’re still waiting for the experiment that will convince everyone that we understand this.

So why does the Moon look larger on the horizon? We don’t really know, but scientists are still trying to figure it out.

NASA asked artists to imagine the future of deep space exploration in artwork meant to inspire the Artemis Generation. The NASA Moon to Mars Architecture art challenge sought creative images that represent the agency’s bold vision for crewed exploration of the lunar surface and the Red Planet. The agency has selected the recipients of the art challenge competition.  

The challenge, hosted by contractor yet2 through NASA’s Prizes, Challenges, and Crowdsourcing program, was open to artists from around the globe. Guidelines asked artists to consider NASA’s Moon to Mars Architecture development effort, which uses engineering processes to distil NASA’s Moon to Mars Objectives into the systems needed to accomplish them. NASA received 313 submissions from 22 U.S. states and 47 countries.

The architecture includes four segments of increasing complexity. For this competition, NASA sought artistic representations of the two furthest on the timeline: the Sustained Lunar Evolution segment and the Humans to Mars segment.

• The Sustained Lunar Evolution segment is an open canvas for exploration of the Moon, embracing new ideas, systems, and partners to grow to a long-term presence on the lunar surface. Sustained lunar evolution means more astronauts on the Moon for longer periods of time, increased opportunities for science, and even the large-scale production of goods and services derived from lunar resources. It also means increased cooperation and collaboration with international partners and the aerospace industry to build a robust lunar economy.  

• The Humans to Mars segment will see the first human missions to Mars, building on the lessons we learn from exploring the Moon. These early missions will focus on Martian exploration and establishing the foundation for a sustained Mars presence. NASA architects are examining a wide variety of options for transportation, habitation, power generation, utilization of Martian resources, scientific investigations, and more.

Final judging for the competition took place at NASA’s annual Architecture Concept Review meeting. That review brought together agency leadership from NASA mission directorates, centers, and technical authorities to review the 2024 updates to the Moon to Mars Architecture. NASA selected the winning images below during that review:

The NASA Tournament Lab, part of the Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate, managed the challenge. The program supports global public competitions and crowdsourcing as tools to advance NASA research and development and other mission needs.

You would not expect to see NASA at a car show—but that’s exactly where Johnson Space Center employees were from Jan. 29 to Feb. 2, 2025, driving the future of space exploration forward. 

At the Houston AutoBoative Show, a fusion of the auto and boat show, NASA rolled out its Artemis exhibit at NRG Center for the first time, introducing vehicle enthusiasts to the technologies NASA and commercial partners will use to explore more of the lunar surface than ever before. 

The Artemis exhibit stood alongside some of the world’s most advanced cars and boats, offering visitors an up-close look at lunar terrain vehicle mockups from Astrolab, Intuitive Machines, and Lunar Outpost. Later this year, NASA will select the rover that will fly to the Moon as humanity prepares for the next giant leap. 

In addition to the rovers, the exhibit featured a mockup of JAXA’s (Japan Aerospace Exploration Agency) pressurized rover, designed as a mobile habitat for astronauts, and Axiom Space’s lunar spacesuit, developed for Artemis III astronauts. 

These capabilities will allow astronauts to explore, conduct science research, and live and work on the lunar surface.  

Johnson Director Vanessa Wyche visited the Artemis exhibit to highlight the importance of these technologies in advancing lunar exploration. Every lesson learned on the Moon will help scientists and engineers develop the strategies, technologies, and experience needed to send astronauts to Mars.  

“By bringing the excitement of lunar exploration to the AutoBoative Show, NASA aims to inspire the next generation of explorers to dream bigger, push farther, and help shape humanity’s future in space,” Wyche said.  

NASA’s Artemis campaign is setting the stage for long-term human exploration, working with commercial and international partners to establish a sustained presence on the Moon before progressing to Mars. 

To make this vision a reality, NASA is developing rockets, spacecraft, landing systems, spacesuits, rovers, habitats, and more.  

Some of the key elements on display at the show included:

• The Orion spacecraft – Designed to take astronauts farther into deep space. Orion will launch atop NASA’s Space Launch System (SLS) rocket, carrying the crew to the Moon on Artemis missions and safely returning them to Earth.

• Lunar terrain vehicles – Developed to transport astronauts across the rugged lunar surface or be remotely operated. NASA recently put these rover mockups to the test at Johnson, where astronauts and engineers, wearing spacesuits, ran through critical maneuvers, tasks, and emergency drills—including a simulated crew rescue.

• Next-gen spacesuits and tools – Through Johnson’s Extravehicular Activity and Human Surface Mobility Program, astronauts’ gear and equipment are designed to ensure safety and efficiency while working on the Moon’s surface.

Guests had the chance to step into the role of an astronaut with interactive experiences like: 

• Driving a lunar rover simulator – Testing their skills at the wheel of a virtual Moon rover. 

• Practicing a simulated Orion docking – Experiencing the precision needed to connect to Gateway in lunar orbit. 

• Exploring Artemis II and III mission roadmaps – Learning about NASA’s upcoming missions and goals. 

Attendees also discovered how American companies are delivering science and technology to the Moon through NASA’s Commercial Lunar Payload Services initiative. 

“Everyone can relate to exploration, so it was great to teach people the importance lunar rovers will have on astronauts’ abilities to explore more of the lunar surface while conducting science,” said Victoria Ugalde, communications strategist for the Extravehicular Activity and Human Surface Mobility Program, who coordinated the lunar rovers’ appearance at the show.

Measuring water loss from space

This study showed that the International Space Station’s ECOSTRESS instrument estimates of evapotranspiration (transfer of water to the atmosphere from Earth’s surface and plants) are comparable to ground-based reference values. This finding suggests space measurements could provide guidance for improved water management on large scales.

Worsening droughts due to climate change require better water management. Evapotranspiration is a critical part of the hydrologic cycle, but data are lacking on local water conditions and demands. California’s Eastern Municipal Water District uses the ground-based California Irrigation Management Information System to track evapotranspiration, but it has limited spatial coverage and consistency. Space-based estimates could be better and more consistent.

Four-legged robotic retrievers

Space station crew members successfully located and retrieved an object in a simulated Mars environment using a remotely controlled four-legged robot, Bert. Legged robots could provide the ability to explore and survey different extraterrestrial surfaces on future missions.

On uneven lunar and planetary surfaces, robots with legs could explore areas inaccessible to wheeled rovers. Surface Avatar, an investigation from ESA (European Space Agency), evaluated remote control of multiple robots in space, providing information on how human operators respond to physical feedback (such as feeling a bump when a robot arm makes contact) and identifying challenges for orbit-to-ground remote operation of robots. The German Aerospace Center is developing Bert.

Technology supports atmospheric studies

Researchers found that the Compact Thermal Imager (CTI) on the space station produced scientifically useful imagery of atmospheric phenomena, including gravity waves, clouds, and volcanic plumes. This technology could change current practices and instrument design for remote sensing of Earth from space.

The CTI is mounted on hardware for Robotic Refueling Mission 3, which tested technology for the robotic transfer and storage of cryogenic fluids in microgravity. The station’s orbit provides near-global coverage and CTI has reduced size, energy use, and cost. Its images can measure fires, ice sheets, glaciers, and snow surface temperatures on the ground and the transfer of water from soil and plants into the atmosphere.

Dozens of suits have been filed that seek to stop some of President Trump’s executive orders. Here’s a brief rundown.

The order came in response to a lawsuit filed by 19 attorneys general accusing the president of failing to faithfully execute the nation’s laws when he let DOGE comb through federal computer systems.

A coalition of attorneys general are seeking to bypass President Joe Biden's last-minute preemptive pardon of Dr. Anthony Fauci to investigate him on a state level for his role in the COVID-19 pandemic response.

The post Republican Attorneys General Seek to Bypass Biden Pardon, Investigate Fauci on State Level appeared first on Breitbart.

Newly-sworn in U.S. Attorney General Pam Bondi has gotten straight to work on her first day by directing the Department of Justice (DOJ) to "pause all federal funding for sanctuary cities," according to a Wednesday report.

The post Report: AG Pam Bondi Orders DOJ to Pause Federal Funding to Sanctuary Cities appeared first on Breitbart.

The department’s current No. 2 official, Emil Bove, escalated his growing conflict with the interim leadership of the F.B.I.

NASA’s Ames Research Center in Silicon Valley invites media to learn more about Distributed Spacecraft Autonomy (DSA), a technology that allows individual spacecraft to make independent decisions while collaborating with each other to achieve common goals – without human input. The DSA team achieved multiple firsts during tests of such swarm technology as part of the agency’s project. 

DSA develops software tools critical for future autonomous, distributed, and intelligent spacecraft that will need to interact with each other to achieve complex mission objectives. Testing onboard the agency’s Starling mission resulted in accomplishments including the first fully distributed autonomous operation of multiple spacecraft, the first use of space-to-space communications to autonomously share status information between multiple spacecraft, and more. 

DSA’s accomplishments mark a significant milestone in advancing autonomous systems that will make new types of science and exploration possible. 

Caleb Adams, DSA project manager, is available for interview on Wednesday, Feb. 5 and Thursday, Feb. 6. To request an interview, media can contact the Ames Office of Communications by email at arc-dl-newsroom@nasa.gov or by phone at 650-604-4789.

For astronauts aboard the International Space Station, staying connected to loved ones and maintaining a sense of normalcy is critical. That is where Tandra Gill Spain, a computer resources senior project manager in NASA’s Avionics and Software Office, comes in. Spain leads the integration of applications on Apple devices and the hardware integration on the Joint Station Local Area Network, which connects the systems from various space agencies on the International Space Station. She also provides technical lead support to the Systems Engineering and Space Operations Computing teams and certifies hardware for use on the orbiting laboratory. 

Spain shares about her career with NASA and more. Read on to learn about her story, her favorite project, and the advice she has for the next generation of explorers. 

Where are you from? 

I am from Milwaukee, Wisconsin. 

Tell us about your role at NASA. 

I am the Apple subsystem manager where I lead the integration of applications on Apple devices as well as the hardware integration on the Joint Station Local Area Network. We use a variety of different software but I work specifically with our Apple products. I also provide technical lead support to the Systems Engineering and Space Operations Computing teams. In addition, I select and oversee the certification of hardware for use on the International Space Station, and I research commonly used technology and assess applicability to space operations.   

How would you describe your job to family or friends who may not be familiar with NASA? 

I get the opportunity to provide the iPads and associated applications that give astronauts the resources to access the internet. Having access to the internet affords them the opportunity to stay as connected as they desire with what is going on back home on Earth (e.g., stream media content, stay in touch with family and friends, and even pay bills). I also provide hardware such as Bluetooth speakers, AirPods, video projectors, and screens. 

How long have you been working for NASA? 

I have been with the agency for 30 years, including 22 years as a contractor. 

What advice would you give to young individuals aspiring to work in the space industry or at NASA? 

I have found that there is a place for just about everyone at NASA, therefore, follow your passion.  Although many of us are, you don’t have to be a scientist or engineer to work at NASA. Yearn to learn.  Pause and listen to those around you. You don’t know what you don’t know, and you will be amazed what gems you’ll learn in the most unexpected situations. 

Additionally, be flexible and find gratitude in every experience. Many of the roles that I’ve had over the years didn’t come from a well-crafted, laid-out plan that I executed, but came from taking advantage of the opportunities that presented themselves and doing them to the best of my ability. 

What was your path to NASA? 

I moved to Houston to work at NASA’s Johnson Space Center immediately upon graduating from college. 

Is there someone in the space, aerospace, or science industry that has motivated or inspired you to work for the space program? Or someone you discovered while working for NASA who inspires you?  

I spent over half of my career in the Astronaut Office, and I’ve been influenced in different ways by different people, so it wouldn’t be fair to pick just one! 

What is your favorite NASA memory? 

I’ve worked on so many meaningful projects, but there are two recent projects that stand out.

Humans were not created to be alone, and connection is extremely important. I was able to provide a telehealth platform for astronauts to autonomously video conference with friends and family whenever an internet connection is available. Prior to having this capability, crew were limited to one scheduled video conference a week. It makes me emotional to think that we have moms and dads orbiting the Earth on the space station and they can see their babies before they go to bed, when they wake up in the morning, or even in the middle of the night if needed.  

In addition, since iPads are used for work as well as personal activities on station, it is important for my team to be able to efficiently keep the applications and security patches up to date. We completed the software integration and are in the process of wrapping up the certification of the Mac Mini to provide this capability. This will allow us to keep up with all software updates that Apple releases on a regular basis and minimize the amount of crew and flight controller team time associated with the task by approximately 85%. 

What do you love sharing about station? What’s important to get across to general audiences to help them understand the benefits to life on Earth? 

When I speak to the public about the space station, I like to compare our everyday lives on Earth to life on the station and highlight the use of technology to maintain the connection to those on Earth. For example, most people have a phone. Besides making a phone call, what do you use your phone for? It is amazing to know that the same capabilities exist on station, such as using apps, participating in parent teacher conferences, and more. 

If you could have dinner with any astronaut, past or present, who would it be? 

I would have dinner with NASA astronaut Ron McNair. He graduated from the same university as I did, and I’ve heard great stories about him. 

Do you have a favorite space-related memory or moment that stands out to you? 

As I mentioned previously, human connection is extremely important. As an engineer in the Astronaut Office, I worked on a project that provided more frequent email updates when Ku-Band communication was available. Previously, email was synced two to three times a day, and less on the weekend. When the capability went active, I sent the first email exchange. 

What are some of the key projects you’ve worked on during your time at NASA? What have been your favorite?  

There have been so many projects over the past 30 years that I don’t think I could select just one. There is something however, that I’ve done on many occasions that has brought me pure joy, which is attending outreach events as Johnson’s “Cosmo” mascot, especially Houston Astros games.    

What are your hobbies/things you enjoy outside of work? 

I enjoy crafting, traveling, mentoring students in Pearland Independent School District, spending time with family, and my Rooted Together community. 

Day launch or night launch?  

Night launch! 

Favorite space movie? 

Star Wars (the original version)
