Deputy Observatory Manager – Goddard Space Flight Center Growing up in Malaysia and Singapore, Hsiao Smith — now the deputy observatory manager for NASA’s Nancy Grace Roman Space Telescope — never imagined she’d have a career at NASA. But when she moved near NASA’s Goddard Space Flight Center in Greenbelt, Maryland, things quickly fell into place. A high school counselor noticed her aptitude for math and science and encouraged her to apply for a junior fellowship program at Goddard. “I never could have imagined that a summer internship would change my life and lead to such a fulfilling career at NASA!” Hsiao says. “Prior to that, I had no idea what an engineer did.…

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 distr…

NASA This Feb. 5, 1971, photo gives an excellent view of the Apollo 14 lunar module on the Moon’s surface after landing. At left, we can see that the astronauts – Alan Shepard and Edgar Mitchell – deployed the U.S. flag before taking this photo of the lunar module. Shepard and Mitchell touched down in the Fra Mauro highlands region and conducted two moonwalks lasting more than nine hours in total. They set up an experiment package and collected 93 pounds of rock and soil samples to return to waiting scientists on Earth. In the meantime, astronaut Stuart Roosa, who remained in orbit aboard the command module, conducted observations and photography of the lunar surfac…

5 Min Read Planetary Alignments and Planet Parades A sky chart showing Mars, Jupiter, Saturn, and Venus in a “planet parade.” Credits: NASA/JPL-Caltech On most nights, weather permitting, you can spot at least one bright planet in the night sky. While two or three planets are commonly visible in the hours around sunset, occasionally four or five bright planets can be seen simultaneously with the naked eye. These events, often called “planet parades” or “planetary alignments,” can generate significant public interest. Though not exceedingly rare, they’re worth observing since they don’t happen every year. Why Planets …

NASA, ESA, CSA, and STScI This image from NASA’s Hubble Space Telescope, released on Feb. 4, 2025, shows the gargantuan galaxy LEDA 1313424, aptly nicknamed the Bullseye. A far smaller blue dwarf galaxy went through the Bullseye’s center, leaving nine star-filled rings. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings. Hubble and Keck’s follow-up observations also helped the researchers prove which galaxy plunged through the center of the Bullseye…

Seeds survive space A close-up view of the Materials International Space Station Experiment hardware housing materials for exposure to space.NASA Researchers found that plant seeds exposed to space germinated at the same rate as those kept on the ground. This finding shows that plant seeds can remain viable during long-term space travel and plants could be used for food and other uses on future missions. Materials International Space Station Experiment-14 exposed a variety of materials to space, including 11 types of plant seeds. The work also evaluated the performance of a new sample containment canister as a method of exposing biological samples to space w…

3 Min Read How Does the Sun Behave? (Grades K-4) This article is for students grades K-4. The Sun is a star. It is the biggest object in our solar system. The Sun is about 93 million miles away from Earth and about 4.5 billion years old. The Sun affects Earth’s weather, seasons, climate, and more. Let’s learn about how the Sun behaves. Why is the Sun warm and bright? The Sun is a giant ball made of hydrogen and helium gases. Deep in the center of the Sun, hydrogen atoms are pressed together. This forms helium. When this happens, energy is released. That energy is the heat and…
