Do NASA Science LIVE on February 21! What’s it mean to be cool?

Snow and ice are everywhere this time of year—mountain tops, Alaska, and even outer space. Grab a cup of hot cocoa and join us for the next Do NASA Science LIVE event as we explore ways to participate in NASA’s winter-themed volunteer research projects. On this interactive Zoom call, you’ll chat with five scientists who will describe how you can participate in their NASA research. No previous experience is required—just access to a computer or smartphone. Registration is free, required, and now open.

Discover how to fill important data gaps in understanding what “cold” means on Earth AND in space. Sometimes cold is relative and the coldest objects in space—still warmer than Jupiter– are vital for teaching us about how stars and planets form. Help us understand and protect our own planet too! We will hear from the researchers behind: Mountain Rain or Snow, Fresh Eyes on Ice, Backyard Worlds: Cool Neighbors, GLOBE Observer Land Cover, and the Sungrazer Project.

Register here to join in the conversation, connect with scientists, and contribute to real science: February 21st at 7pm ET for “What’s it mean to be cool?”. Bring the whole family! Everyone is welcome.

NASA Welcomes Greece as Newest Artemis Accords Signatory

NASA Administrator Bill Nelson participated in a signing ceremony Friday with Greece’s foreign minister, Giorgos Gerapetritis, as his country became the 35th country to sign the Artemis Accords.

The accords establish a practical set of principles to guide space exploration cooperation among nations.

Also participating in the event at the U.S. Department of State were NASA Deputy Administrator Pam Melroy, U.S. Secretary of State Antony Blinken, and Dr. Ioannis Daglis, president of the Hellenic Space Center. The signing occurred during the fifth United States-Greece Strategic Dialogue in Washington.

“Congratulations to Greece on becoming the 35th country to join the Artemis Accords family,” said Nelson. “The U.S. and Greece are long-time partners and friends, and we are excited to expand this partnership in the cosmos. Together, we are shaping the future of cooperation in space for the Artemis Generation.”

The Artemis Accords were established in 2020 by the United States together with seven other original signatories. Since then, the Accords signatories have held focused discussions on how best to implement the Artemis Accords principles.

“As humanity embarks on a great adventure, returning to the Moon and preparing for traveling beyond the Moon, the Artemis Accords serve as a beacon of collaboration and cooperation among nations, paving the way for a sustainable and peaceful exploration of space,” said Gerapetritis.

The Artemis Accords reinforce and implement key obligations in the 1967 Outer Space Treaty. They also strengthen the commitment by the United States and signatory nations to the Registration Convention, the Rescue and Return Agreement, as well as best practices NASA and its partners support, including the public release of scientific data.

More countries are expected to sign the accords in the months and years ahead, which are advancing safe, peaceful, and prosperous activities in space. Learn more about the Artemis Accords at:

Rahul Ramachandran Essay Published on NASA’s EarthData

January 29, 2024 / Earth Science

Rahul Ramachandran (ST11) wrote his American Geophysical Union (AGU)  Leptoukh lecture as an essay titled “From petabytes to Insights: Tackling Earth Science’s Scaling Problem ”. While Ramachandran was unable to present at AGU, the essay was published on NASA EarthData website (https://www.earthdata.nasa.gov/learn/articles/2023-leptoukh-lecture-essay).

The essay addresses the challenge of scaling in Earth science due to increasing data volumes. Ramachandran discusses the integration of Artificial Intelligence into informatics as a potential solution to these challenges. He reflects on his journey in informatics and emphasizes the importance of managing the science data life cycle effectively in the face of ever-growing data volumes, advocating for innovative approaches to support the research life cycle.

Third NASA Enabled Private Flight to Space Station Completes Safely 

The third private astronaut mission to the International Space Station successfully completed its journey as part of NASA efforts to create commercial opportunities in space. Axiom Mission 3 (Ax-3) and its four crew members safely returned to Earth Friday, splashing down off the coast of Daytona, Florida. 

Axiom Space astronauts, Michael López-Alegría, Walter Villadei, Marcus Wandt, and Alper Gezeravci returned to Earth aboard a SpaceX Dragon spacecraft at 8:30 a.m. EST, completing their nearly 22-day mission that included 18 days aboard the space station. Teams aboard SpaceX recovery vessels retrieved the spacecraft and astronauts. 

“Low Earth orbit is now within humanity’s economic sphere of influence. It presents the best opportunities for the U.S. commercial space sector to capture new global and domestic markets and to provide critical capabilities to the nation’s space objectives,” said Phil McAlister, director of NASA’s commercial space division at NASA Headquarters in Washington. “This ground-breaking Ax-3 mission is part of a larger effort, enabled by NASA, to open space to more people, more research, and more opportunities as the agency prepares for the transition to future private space stations at the end of this decade.” 

The Ax-3 mission launched at 4:49 p.m. Jan. 18 on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. Approximately 37 hours later, Dragon docked to the Harmony module’s forward port. The astronauts undocked from the same port at 9:20 a.m. Wednesday, to begin the trip home. 

The crew spent over two weeks conducting microgravity research, educational outreach, and commercial activities. The spacecraft returns to Florida for inspection and processing at SpaceX’s refurbishing facility at Cape Canaveral Space Force Station, where teams will examine the spacecraft’s data and performance throughout the flight. Throughout their mission, the astronauts conducted over 30 science experiments, and returned science, including NASA cargo, back to Earth. 

Supporting private astronaut missions is part of NASA’s strategy to create a vibrant commercial economy in orbit where the agency will become just one of many customers. 

The Ax-3 mission embodies the culmination of NASA’s efforts to foster a commercial market in low Earth orbit and continue a new era of space exploration that enables more people and organizations to fly multiple mission objectives. This partnership expands the arc of human spaceflight history and opens access to low Earth orbit and the International Space Station to more people, science, and commercial opportunities.
