Take a deep dive into the science of NASA’s Nancy Grace Roman Space Telescope with Julie McEnery, Roman's senior project scientist. In this video episode of NASA's Curious Universe podcast, learn why Roman’s survey data will be so detailed that they could cover a 4K screen the size of dozens of city blocks and why Julie says she doesn’t hope Roman changes our understanding of the universe—she knows it will.

![Is This How Mars Lost Its Atmosphere?
Mars is losing its atmosphere. Over billions of years, the Red Planet has transformed from a potentially habitable world with lakes, rivers, and a thicker atmosphere into the cold, dry desert we see today. NASA’s MAVEN mission has been tracking this process in real time, catching Mars in the act of slowly sputtering its atmosphere into space.
This phenomenon—called “atmospheric sputtering”—happens when high-energy particles from the Sun slam into Mars’s upper atmosphere, knocking atoms and molecules loose. Without a global magnetic field to protect it, Mars is especially vulnerable. MAVEN has shown that this atmospheric escape accelerates during solar storms, offering a powerful view of how the Sun shapes the evolution of planetary atmospheres.
The data from MAVEN doesn’t just tell us about Mars—it helps us understand how atmospheres behave across the solar system and beyond. It’s a glimpse into what makes a planet stay habitable—or lose that potential entirely.

![5 Ways NASA Uses Solar Power
From studying life on Earth to powering spacecraft across the solar system, NASA uses solar power to explore near and far.
In September 2024, the Heliophysics Big Year theme is Environment and Sustainability. The Heliophysics Big Year is a global celebration of the Sun’s influence on Earth and the entire solar system. From Oct. 14, 2023, to Dec. 24, 2024, the Heliophysics Big Year celebrates under a theme, sharing opportunities to participate in many solar science events and activities. During the Heliophysics Big Year, participation isn’t limited to science – NASA invites everyone to celebrate the Sun with as many Sun-related activities as they can.

![White Dwarf Eating Pluto-Like Object
In a nearby corner of our galactic neighborhood, NASA’s Hubble Space Telescope just caught a white dwarf star having a cosmic snack.
This burned-out star is about half the mass of our Sun, crammed into a body the size of Earth, and it’s tearing apart something a lot like Pluto.
Thanks to Hubble, we are not only witnessing a star’s strange appetite, but glimpsing our own solar system’s possible future.

![NASAs Roman Space Telescope Hardware Highlights: Summer/Fall 2024
Every day, the Nancy Grace Roman Space Telescope moves closer to completion. This video highlights some of the important hardware milestones from part of this journey. Components and systems are built separately, tested, and then integrated with larger parts of the spacecraft to carefully build the full observatory. Roman’s foundation is the primary structure, or spacecraft bus, which houses electronics and support systems. Like the chassis of a car, everything is built up from this aluminum hexagon.
This video, covering the summer and fall of 2024, opens with NASA’s Goddard Space Flight Center’s Space Environment Simulator. This thermal vacuum chamber is used to test Roman’s Instrument Carrier, which will hold and connect the instruments and mirror. Once the hardware is in place, the chamber evacuates the air and generates high and low temperature extremes to simulate the conditions in space. Workers carefully deploy Roman’s High-Gain Antenna to ensure that it will operate as expected. The 5.6-foot (1.7-meter) dish is Roman’s primary means of communication and will be responsible for sending roughly 1.4 terabytes of data back to Earth each day. The Outer Barrel Assembly is tested on Goddard’s 120-foot-diameter centrifuge. This structure will surround and protect Roman’s primary mirror from stray light. Engineers add weights to simulate additional hardware and tip the Outer Barrel Assembly at different angles over multiple spins to certify that it can withstand all the forces it will experience over its life. The Wide Field Instrument (WFI), Roman’s primary science tool, arrives at Goddard after testing at BAE Systems where it was built. Workers push a sealed crate into the clean room where they can remove the WFI and test it to ensure it made the trip safely. The Optical Telescope Assembly is a combination of the 7.9-foot (2.4-meter) primary mirror, the smaller secondary mirror, and many additional optical elements designed to direct the focused beam of light to Roman’s two instruments. It was built and tested at L3Harris and is the last major piece of hardware to arrive at Goddard. Its special shipping container will also house the completed Roman telescope when it leaves for launch. The Coronagraph Instrument is the first major component integrated, or connected, to the Instrument Carrier. The Coronagraph is a technology demonstration capable of directly image planets outside our solar system, was developed and built at JPL in California. The Optical Telescope Assembly is the next piece integrated. It has to be carefully aligned with the Coronagraph so that light from the mirrors can perfectly pass through an opening in the Coronagraph. First comes mechanical integration, where the hardware is physically connected, and then comes electrical integration where all the various electrical systems are hooked up. The final piece is the Wide Field Instrument. Engineers carefully align it with an opening in the Optical Telescope Assembly so light can pass from one to the other. With the addition of this final element, the instruments, mirrors, and carrier are now called the Integrated Payload Assembly. A very large team of engineers and technical crew lift the Integrated Payload Assembly over the Spacecraft Bus and lower it into place. Mechanical integration takes several hours; electrical integration will take days. Now unified, the heart of the Roman spacecraft is complete.
