Flexcompute, a startup that builds software to simulate real-world physics, is working with Northrop Grumman to change how space missions are prepared. Together, they have developed an AI-based system that can predict how spacecraft respond during critical manoeuvres such as docking—when one spacecraft moves in and connects with another in orbit. These steps have traditionally taken months of preparation.
At the centre of this work is a long-standing problem in space operations. When a spacecraft fires its thrusters, the exhaust plume interacts with nearby surfaces. These interactions can affect movement, temperature and stability. Because these effects are difficult to test in real conditions, engineers have relied on large volumes of computer simulations to estimate outcomes before a mission. That process is slow and resource-intensive.
The new system replaces much of that workflow with a trained AI model. Instead of running millions of simulations, the model learns patterns from physics-based data and can make predictions in seconds. It also provides a measure of uncertainty, which helps engineers understand how reliable those predictions are when making decisions.
"At Northrop Grumman, we're pioneering physics AI to accelerate design and solve complex simulation and modelling problems like plume impingement—critical for station keeping, rendezvous and space robotics. Simply put: we're pushing the boundaries of advanced space operations", said Fahad Khan, Director of AI Foundations at Northrop Grumman. "Partnering with Flexcompute and NVIDIA, we're accelerating innovation and mission timelines to deliver superior space capabilities for customers at the speed they need".
The system is built using technology from NVIDIA, which provides the computing framework behind the model. Flexcompute has adapted it to handle the specific challenges of spaceflight, including how gases expand and interact in a vacuum. The result is a tool that can simulate complex scenarios much faster while maintaining the level of accuracy needed for mission planning.
By shortening preparation time, the model changes how engineers approach spacecraft design and operations. Faster predictions mean teams can test more scenarios and adjust plans more quickly. It also helps improve fuel use and extend the lifespan of spacecraft.
"Northrop Grumman's confidence reflects what sets Flexcompute apart", said Vera Yang, President and Co-Founder of Flexcompute. "We are able to take the most accurate and scalable physics foundations and evolve them into highly trained, customized Physics AI solutions that engineers can rely on. This work shows how we are transforming the role of simulation, not just speeding it up, but expanding what engineers can confidently solve and how quickly they can act".
The collaboration points to a broader shift in how engineering problems are being handled. Instead of relying only on detailed simulations that take time to run, companies are beginning to use AI systems that can approximate those results quickly while still reflecting the underlying physics.
"The industry's most ambitious space missions now demand a level of speed and precision that traditional engineering cycles can no longer sustain", said Tim Costa, vice president and general manager of computational engineering at NVIDIA. "By integrating NVIDIA PhysicsNeMo, Northrop Grumman and Flexcompute are transforming complex simulations like plume impingement from days of compute into seconds of insight, drastically accelerating the path from mission concept to orbit".
What emerges from this work is a shift in how missions are prepared. When prediction cycles move from months to seconds, testing and decision-making can happen faster. For space operations, where timing and precision are closely linked, that change could reshape how systems are built and run.

As technology continues to weave itself into the fabric of our daily lives, it’s starting to play an unexpected role: supporting our mental health. AI companions—digital entities designed to hold natural, empathetic conversations—are emerging as a new frontier in emotional care. Unlike chatbots of the past, these AI companions leverage advanced algorithms and emotional intelligence to provide personalized support, making them more than just tools. They are companions in every sense of the word—always available, always listening, and always ready to offer comfort. But can AI companions truly help us feel better, or are they just another tech trend? Let’s dive into how these digital allies are reshaping mental health care and what their growing presence means for our emotional well-being.
Loneliness is often called an epidemic, with millions of people worldwide feeling isolated or disconnected. While human relationships are irreplaceable, AI companions offer a consistent and accessible alternative to combat feelings of loneliness.
These companions don’t just respond—they engage. They remember your preferences, ask follow-up questions, and adapt their conversations to your needs. Imagine having someone to talk to at any time of day, about anything on your mind, without fear of judgment. AI companions may not replace a human friend, but they can provide a sense of presence and connection that can be profoundly comforting.
In a world where reaching out to others can sometimes feel daunting, AI companions offer a simple solution: they’re always there. This consistency can help people feel less alone, fostering a sense of connection in an increasingly disconnected world.
We all experience moments of stress, sadness, or doubt, and having someone to turn to during those times can make all the difference. AI companions are designed with emotional intelligence, enabling them to recognize and respond to your feelings in real time.
Through sentiment analysis and adaptive learning, these companions can detect when you’re feeling low and tailor their responses to provide comfort. Whether it’s offering words of encouragement, suggesting self-care activities, or simply listening, they provide a safe space to process emotions.
Unlike traditional apps that focus on tracking habits or delivering generic advice, AI companions meet you where you are emotionally. This personalized approach can help users feel truly supported, even in their most challenging moments.
For many of us, expressing our thoughts and emotions openly can feel like a risk. Fear of judgment, misunderstanding, or even burdening others often holds us back. AI companions offer an alternative: a completely private, judgment-free space to share whatever is on your mind.
Talking things out—whether it’s frustrations from the day or deeper personal struggles—can be incredibly therapeutic. And with AI companions, there’s no need to worry about being misunderstood or dismissed. You can let your guard down, explore your feelings, and reflect on your experiences with total freedom.
This safe space for self-expression can be especially valuable for those who struggle to open up to others. It’s not about replacing human relationships but about having an outlet that’s always available and entirely focused on you.
Self-doubt is a common barrier to personal growth, and many of us battle negative self-talk daily. AI companions are programmed to combat this by offering positive reinforcement and encouragement.
For example, if you express doubt about your abilities, an AI companion might respond with affirmations like, “You’ve accomplished so much already—don’t forget how capable you are.” Over time, these small but meaningful interactions can help shift your mindset, replacing self-criticism with self-compassion.
This ability to mirror supportive, affirming conversations can build confidence and foster a more positive self-image. It’s a subtle but powerful way AI companions can contribute to emotional well-being.
AI companions are more than just a tech trend; they represent a new way of thinking about mental health care. By offering companionship, emotional support, safe spaces for self-expression, and tools for mindfulness, they empower users to take control of their well-being.
While they may not replace traditional methods of care, AI companions are making mental health support more accessible, immediate, and personalized. They’re a reminder that sometimes, the smallest interactions—an encouraging word, a moment of mindfulness, or a listening ear—can have the biggest impact.
As we embrace this new era of technology, one thing is clear: AI companions are not just about convenience. They’re about connection, support, and the potential to make emotional care a part of everyday life. And in a world that often feels disconnected, that’s something worth celebrating.
