Six Ways Supercomputing Advances Our Understanding of the Universe

NeRD

At NASA, high-end computing is essential for many agency missions. This technology helps us advance our understanding of the universe – from our planet to the farthest reaches of the cosmos. Supercomputers enable projects across diverse research, such as making discoveries about the Sun’s activity that affects technologies in space and life on Earth, building artificial intelligence-based models for innovative weather and climate science, and helping redesign the launch pad that will send astronauts to space with Artemis II.  These projects are just a sample of the many on display in…

Two Years Ago: Artemis I Liftoff

NeRD

NASA/Joel Kowsky In this photo, NASA’s SLS (Space Launch System) rocket, carrying the Orion spacecraft, lifts off the pad at Launch Complex 39B at the agency’s Kennedy Space Center in Florida at 1:47 a.m. EST on Nov. 16, 2022. Set on a path to the Moon, this officially began the Artemis I mission. Since the completion of Orion’s 25.5-day mission around the Moon and back, teams across NASA have been hard at work preparing for the upcoming Artemis II test flight, which will send four astronauts on a 10-day mission around…

NASA Satellites Reveal Abrupt Drop in Global Freshwater Levels

NeRD

4 min read NASA Satellites Reveal Abrupt Drop in Global Freshwater Levels Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers GRACE satellites measure gravity as they orbit the planet to reveal shifting levels of water on the Earth (artist’s concept). NASA/JPL-Caltech An international team of scientists using observations from NASA-German satellites found evidence that Earth’s total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the researchers suggested the shift could indicate Earth’s…

Aurora activity is just getting started. Here’s why the best northern lights are yet to come.

NeRD

There’s no doubt we’ve been treated to some remarkable aurora shows this year (the May superstorms and the recent strong activity in October spring to mind) but what if I told you this was only the beginning of some incredible northern lights activity? In October 2024, scientists announced that the sun has reached solar maximum, a period of heightened solar activity and sunspot frequency that occurs during the sun‘s approximately 11-year solar cycle. During the solar maximum period, the sun emits more energized particles as it erupts with coronal mass…

Did NASA’s Viking landers accidentally kill life on Mars? Why one scientist thinks so

NeRD

In 1975, NASA’s Viking 1 spacecraft entered orbit around Mars, carrying a mission to unlock the secrets of the Red Planet. Soon, it released twin landers that drifted toward the Martian surface and eventually made history as the first American spacecraft to touch down on the world. For over six years, Viking 1 continued to orbit Mars’ Chryse Planitia region while its landers collected soil samples using robotic arms and onboard laboratories, marking a groundbreaking chapter in humanity’s exploration of the Martian environment. At the time, however, little was known…

Parallels between spaceflight and the aging process may extend to encompass frailty.Figure Left: Venn diagram of differentially expressed frailty genes in rodent and human samples shows the common differentially expressed genes between the two species.Figure Right: Schematic of the Inspiration4 experiments and samples.This study relied on data from the OSDR, including 7 rodent spaceflight datasets, 2 human space analog datasets, astronaut data from the Japan Aerospace Exploration Agency (JAXA) and Inspiration4. Data on sarcopenia were mined from National Center for Biotechnology Information’s Gene Expression Omnibus. Spaceflight accelerates the symptoms of…
