https://youtu.be/63uNNcCpxHI How are we made of star stuff?
Well, the important thing to understand about this question is that it’s not an analogy, it’s literally true.
The elements in our bodies, the elements that make up our bones, the trees we see outside, the other planets in the solar system, other stars in the galaxy. These were all part of stars that existed well before our Sun and Earth and solar system were even formed.
The universe existed for billions of years before we did. And all of these elements that you see on the periodic table, you see carbon and oxygen and silicon and iron, the common elements throughout the universe, were all put there by previous generations of stars that either blew off winds like the Sun blows off a solar wind, or exploded in supernova explosions and thrust their elements throughout the universe.
These are the same things that we can trace with modern telescopes, like the Hubble Telescope and the James Webb Space Telescope, the Chandra X-ray Observatory. These are all elements that we can map out in the universe with these observatories and trace back to the same things that form us and the elemental abundances that we see in stars now are the same things that we see in the Earth’s crust, we see in asteroids. And so we know that these are the same elements that were once part of these stars.
So the question of, “How are we made of star stuff?”, in the words of Carl Sagan, “The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Piloted by NASA’s Tim Williams, the ER-2 science aircraft ascends for one of the final science flights for the GSFC Lidar Observation and Validation Experiment (GLOVE) on Feb. 1, 2025. As a collaboration between engineers, scientists, and aircraft professionals, GLOVE aims to improve satellite data products for Earth Science applications. NASA/Steve Freeman In February, NASA’s ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is exploring how instruments analyzing clouds can improve data measurement methods.
Researchers participating in the Goddard Space Flight Center Lidar Observation and Validation Experiment (GLOVE) used the ER-2 – based at NASA’s Armstrong Flight Research Center in Edwards, California – to validate satellite data about cloud and airborne particles in the Earth’s atmosphere. Scientists are using GLOVE instruments installed onboard the aircraft to measure and validate data about clouds generated by satellite sensors already orbiting in space around Earth.
“The GLOVE data will allow us to test new artificial intelligence algorithms in data processing,” said John Yorks, principal investigator for GLOVE and research physical scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “These algorithms aim to improve the cloud and aerosol detection in data produced by the satellites.”
Jennifer Moore, a researcher from NASA’s Goddard Space Flight Center, checks the cabling on the Roscoe instrument at NASA’s Armstrong Flight Research Center in Edwards, California, for the GSFC Lidar Observation and Validation Experiment (GLOVE) on Feb. 1, 2025. The Roscoe instrument will be uploaded onto NASA’s ER-2 science aircraft.NASA/Steve Freeman The validation provided by GLOVE is crucial because it ensures the accuracy and reliability of satellite data. “The instruments on the plane provide a higher resolution measurement ‘truth’ to ensure the data is a true representation of the atmospheric scene being sampled,” Yorks said.
The ER-2 flew over various parts of Oregon, Arizona, Utah, and Nevada, as well as over the Pacific Ocean off the coast of California. These regions reflected various types of atmospheres, including cirrus clouds, marine stratocumulus, rain and snow, and areas with multiple types of clouds.
“The goal is to improve satellite data products for Earth science applications,” Yorks said. “These measurements allow scientists and decision-makers to confidently use this satellite information for applications like weather forecasting and hazard monitoring.”

The GLOVE instrument will validate data from satellites orbiting the Earth.NASA/Steve Freeman The four instruments installed on the ER-2 were the Cloud Physics Lidar, the Roscoe Lidar, the enhanced Moderate Resolution Imaging Spectroradiometer Airborne Simulator, and the Cloud Radar System. These instruments validate data produced by sensors on NASA’s Ice, Cloud, and Land Elevation Satellite 2 (ICESat-2) and the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE), a joint venture between the ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency).
“Additionally, the EarthCARE satellite is flying the first ever Doppler radar for measurements of air motions within clouds,” Yorks said. While the ER-2 is operated by pilots and aircrew from NASA Armstrong, these instruments are supported by scientists from NASA Goddard, NASA’s Ames Research Center in California’s Silicon Valley, and the Naval Research Laboratory office in Monterey, California, as well as by students from the University of Iowa in Iowa City and the University of Maryland College Park.

Sols 4511-4512: Low energy after a big weekend?
This image was taken by Left Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4510 (2025-04-14 03:43:40 UTC). NASA/JPL-Caltech Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center
Earth planning date: Monday, April 14, 2025
We all know the feeling: it’s Monday morning after a big weekend and you’re coming into the week wishing you’d had a little more time to rest and recharge. Well, Curiosity probably feels the same way today. Curiosity accomplished a lot over the weekend, including full contact science, a MAHLI stereo imaging test, testing the collection of ChemCam passive spectral data at the same time as data transmission with one of the orbiters, and some APXS and MAHLI calibration target activities, plus a long 57 m drive. It was great to see all of those activities in the plan and to see some great drive progress. But that means we’re a bit tight on power for today’s plan!
I was on shift as Long Term Planner today, and the team had to think carefully about science priorities to fit within our power limit for today’s plan, and how that will prepare us for the rest of the week. The team still managed to squeeze a lot of activities into today’s 2-sol plan. First, Curiosity will acquire Mastcam mosaics to investigate local stratigraphic relationships and diagenetic features. Then we’ll acquire some imaging to document the sandy troughs between bedrock blocks to monitor active surface processes. We’ll also take a Navcam mosaic to assess atmospheric dust. The science block includes a ChemCam LIBS observation on the bedrock target “Santa Margarita” and a long distance RMI mosaic of “Ghost Mountain” to look for possible boxwork structures. Then Curiosity will use the DRT, APXS and MAHLI to investigate the finely-laminated bedrock in our workspace at a target named “The Grotto.” We’ll also collect APXS and MAHLI data on a large nodule in the workspace named “Torrey Pines” (meanwhile the Torrey Pines here on Earth was shaking in today’s southern California earthquakes! All is well but it gave some of our team members an extra jolt of adrenaline right before the SOWG meeting). The second sol is focused on continuing our drive to the south and taking post-drive imaging to prepare for Wednesday’s plan.
Phew! Good job Curiosity, you made it through Monday.

Have we ever been to Uranus?
The answer is simple, yes, but only once. The Voyager II spacecraft flew by the planet Uranus back in 1986, during a golden era when the Voyager spacecraft explored all four giant planets of our solar system. It revealed an extreme world, a planet that had been bowled over onto its side by some extreme cataclysm early in the formation of the solar system.
That means that its seasons and its magnetic field get exposed to the most dramatic seasonal variability of any place that we know of in the solar system. The atmosphere was a churning system made of methane and hydrogen and water, with methane clouds showing up as white against the bluer background of the planet itself.
The densely packed ring system is host to a number of very fine, narrow and dusty rings surrounded by a collection of icy satellites. And those satellites may harbor deep, dark, hidden oceans beneath an icy crust of water ice.
Taken together, this extreme and exciting system is somewhere that we simply must go back to explore and hopefully in the next one to two decades NASA and the European Space Agency will mount an ambitious mission to go out there and explore the Uranian system. It’s important not just for solar system science, but also for the growing field of exoplanet science. As planets of this particular size, the size of Uranus, about four times wider than planet Earth, seem to be commonplace throughout our galaxy.
So how have we been to Uranus? Yes, but it’s time that we went back.
