The Pioneer's Journey: From Montana to Mars Mission Planning

Growing up in Montana's Rocky Mountains, Newman developed an early love for exploration. "Since my earliest memories I think of myself as kind of exploring the natural beauty of the Rocky Mountains where I grew up," she recalls. This natural curiosity, combined with witnessing the Apollo 11 moon landing at age five, set her on a path toward space exploration.

"Apollo 11...I distinctly remember that," Newman shares. "It actually just taught me to dream to any impossible mission could be possible with enough focus." This early inspiration convinced her that humans were destined to become an interplanetary species—a vision she's dedicated her career to realizing.

Newman's Twitter handle, @DavaExplorer, reflects this lifelong passion. As she explains, exploration isn't limited to changing domains but encompasses venturing into any unknown territory, whether natural environments or the vastness of space.

The Search for Life on Mars

Newman expresses confidence that we'll discover evidence of past life on Mars within the next decade. "I think actually in probably the next decade we find probably past life, probably the evidence of past life on Mars," she states. Her optimism stems from understanding Mars' history—approximately 3.5 billion years ago, the planet possessed an electromagnetic shield, atmosphere, and favorable gravity (about 38% of Earth's).

The evidence is mounting: scientists have detected organics, seasonal water, and the necessary building blocks for life on Mars. The challenge lies in digging beneath the radiation-exposed surface to find preserved biological markers.

"We've been exploring Mars for 50 years with our robots," Newman notes, explaining that human explorers would dramatically accelerate scientific discovery. She emphasizes that Mars missions represent "extreme exploration"—requiring eight months of travel to reach the planet and approximately a year and a half to return home.

The Artemis Program: A Stepping Stone to Mars

Discussing NASA's current Artemis program, Newman emphasizes the importance of returning to the Moon before attempting Mars missions. "I love the moon program now, Artemis," she says. "We've been in low Earth orbit...but I just always look at those three phases. Low Earth orbit where we've been 40 years, so definitely time to get back to deep space, time to get to the Moon."

The Moon, just three days away from Earth, provides an ideal testing ground for critical technologies:

• Habitats and life support systems
• Spacesuits for planetary exploration
• Deep space radiation protection
• In-situ resource utilization (ISRU)

"To me it really is a lunar testbed," Newman explains, "and then we use those same investments to think about getting people to Mars in the 2030s." She highlights that the Moon's South Pole, with its permanently shaded craters containing water ice, offers valuable resources for fuel and life support systems.

Newman envisions lunar missions lasting a couple of weeks to a month, given the 14-day lunar day/night cycle. While astronauts will pioneer these journeys, she notes that civilian explorers will eventually follow, thanks to policy changes implemented during her NASA tenure that officially recognize non-government astronauts.

The Democratization of Space

Newman celebrates recent developments making space more accessible, including reusable rockets and CubeSats. She acknowledges the complementary roles of government agencies like NASA and private companies such as SpaceX and Blue Origin.

"It's about the most exciting time I can imagine for spaceflight," she enthuses. "It really is the democratization of spaceflight opening it up."

Regarding SpaceX's achievements with reusable rockets, Newman expresses genuine excitement: "Just seeing that rocket come back and land...it never gets old, it's exciting." She compares the precision landings to "gymnastics for rocket ships," noting that reusability represents a "game-changer" for reducing costs and increasing launch frequency.

Newman also highlights the importance of balancing risk cultures between government agencies and private companies. While NASA prioritizes safety and quality assurance, private industry can push boundaries and take calculated risks. "The best scenario is both of them working together," she explains, noting that government agencies provide critical expertise in human spaceflight safety while private companies drive innovation and cost reduction.

Revolutionizing Spacesuits: The BioSuit

Newman's groundbreaking work on the BioSuit represents a paradigm shift in spacesuit design. Traditional spacesuits, which she describes as "the world's smallest spacecraft," are essentially gas-pressurized balloons weighing approximately 140 kilograms that severely limit mobility.

"Since we're going back to the Moon and Mars, we need a planetary suit, we need a mobility suit," Newman explains. Her approach flips the design paradigm by starting with human movement: "I study astronauts, I study humans in motion, and if we can map that motion, I want to give you a full flexibility."

The BioSuit uses mechanical counter-pressure, applying pressure directly to the skin rather than using gas pressurization. This innovative approach:

• Requires only one-third of Earth's atmospheric pressure to keep astronauts alive
• Dramatically reduces mass compared to traditional spacesuits
• Maximizes mobility for planetary exploration
• Incorporates a gas-pressurized helmet that serves as an information portal

"The helmet then really becomes this information portal," Newman envisions. "I'd have augmented reality, you'll have all the information you need...show me the map, show me the topography."

Developing the BioSuit involves a multidisciplinary team including engineers, designers, and architects, ensuring the final product balances functionality with aesthetics. Newman partners with Guillermo Trotti, who brings industrial design expertise to complement her engineering background.

The Future of Space Exploration

Looking ahead, Newman remains optimistic about humanity's spacefaring future while emphasizing Earth's primary importance. "I think that we'll have lots of people—thousands of people, tens of thousands, people who knows, maybe millions—in low Earth orbit," she predicts.

She envisions substantial human presence on both the Moon and Mars within the next century or two, making humanity truly interplanetary. However, she firmly rejects the notion that Mars represents a "Plan B" for human survival.

"I don't think Mars is option B actually. I think it's all about saving spaceship Earth and humanity," Newman states emphatically. "Earth doesn't need us, but we really need...to live in balance with Earth."

Regarding timeline, Newman is committed to making human Mars exploration a reality in the 2030s, following approximately a decade of lunar missions beginning in the mid-2020s. She sees this as a natural progression: "By the later in the decade, in the 2030s, we will have all the technology and know-how...to get that human mission to Mars."

Artificial Intelligence and Autonomous Exploration

When asked about AI's role in space exploration, Newman emphasizes the necessity of fully autonomous systems for Mars missions. With communication delays of approximately 20 minutes between Earth and Mars, traditional mission control becomes impractical.

"For a Mars mission...we need fully autonomous systems," she explains. "People have to be fully autonomous as well, but all of our systems as well."

Interestingly, Newman currently sees AI's most urgent application in analyzing Earth data to address climate change: "Right now, AI is to eyes on Earth, all of our space data, compiling that, using supercomputers because we have so much information and knowledge, and we need to get that into people's hands."

Conclusion: Balancing Exploration with Earthly Responsibility

Throughout the conversation, Newman maintains a balanced perspective on space exploration—enthusiastically advocating for pushing boundaries while recognizing our primary responsibility to Earth. Her vision encompasses both the wonder of discovery and the practical engineering challenges of making interplanetary travel possible.

"We're all astronauts of spaceship Earth," Newman concludes, "and this is our mission—to take care of the planet."

As we look toward the exciting possibilities of lunar bases and Martian expeditions, Newman's expertise reminds us that such ambitious goals require methodical preparation, technological innovation, and international cooperation. Most importantly, they must complement rather than replace our efforts to preserve Earth—humanity's first and most precious home.
