Environmentalist and former Vice President Al Gore visited NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on Oct. 16, 2024, to commemorate the upcoming 10th anniversary of the DSCOVR (Deep Space Climate Observatory) mission.
“The image of our Earth from space is the single most compelling iconic image that any of us have ever seen,” Gore said at a panel discussion for employees. “Now we have, thanks to DSCOVR, 50,000 ‘Blue Marble’ photographs … To date there are more than 100 peer-reviewed scientific publications that are based on the unique science gathered at the L1 point by DSCOVR. For all of the scientists who are here and those on the teams that are represented here, I want to say congratulations and thank you.”

Gore’s visit also entailed a meeting with the DSCOVR science team, a view into the clean room where Goddard is assembling the Roman Space Telescope, and a stop at the control center for PACE: NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem mission.
Launched Feb. 11, 2015, DSCOVR is a space weather station that monitors changes in the solar wind, providing space weather alerts and forecasts for geomagnetic storms that could disrupt power grids, satellites, telecommunications, aviation and GPS.
DSCOVR is a joint mission among NASA, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Air Force. The project originally was called Triana, a mission conceived of by Gore in 1998 during his vice presidency.

NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy visited the agency’s Michoud Assembly Facility in New Orleans on Dec. 8, 2021 for tours and briefings on Michoud’s role in the Artemis program and other capabilities that enrich many facets of the nation’s space exploration endeavors. Credit: NASA/Michael DeMocker NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy will lead the agency’s delegation at the International Astronautical Congress (IAC) from Monday, Oct. 14, to Thursday, Oct. 17, in Milan.
During the congress, NASA will discuss its Low Earth Orbit Microgravity Strategy, emphasizing the agency’s efforts to advance microgravity science, technology, and exploration. The agency also will highlight its commitment to space sustainability and several missions, including initiatives that support NASA’s Moon to Mars exploration approach and the Artemis Accords.
NASA will amplify the following talks happening at the congress through its YouTube Channel:
Monday, Oct. 147:45 a.m. EDT (1:45 p.m. CEST): One-to-One with Heads of Agencies featuring Nelson. 12:15 p.m. EDT (6:15 p.m. CEST): Host Plenary on Responsible and Sustainable Space Exploration for Moon to Mars featuring Melroy. Wednesday, Oct. 16 9 a.m. EDT (3 p.m. CEST): A New Era in Human Presence featuring Melroy. A full agenda for this year’s IAC is available online.
Members of the media registered for IAC will have three opportunities to meet with NASA leaders. To register, media must apply through the International Astronautical Federation website. Opportunities include:
Monday, Oct. 14 5:30 p.m. CEST (11:30 a.m. EDT): NASA Deputy Administrator Pam Melroy, Lisa Campbell, president, CSA (Canadian Space Agency), and Teodoro Valente, president, Italian Space Agency, to discuss the 3rd Annual Heads of Agency meeting of the Artemis Accords Signatories. Tuesday, Oct. 15 5 p.m. CEST (11 a.m. EDT): NASA Administrator Bill Nelson to discuss the agency’s international partnerships in the Artemis era. Wednesday, Oct. 16 5 p.m. CEST (11 a.m. EDT): NASA Deputy Administrator Pam Melroy and Robyn Gatens, director of the International Space Station and acting director of Commercial Spaceflight to discuss NASA’s Low Earth Orbit Microgravity Strategy In addition to the events outlined above, NASA will have an exhibit featuring the first sample of the asteroid Bennu to appear publicly in a non-museum setting, as well as information on the Artemis campaign, NASA’s future in low Earth orbit, and several upcoming science and technology missions. NASA also will host subject matter expert talks throughout the week at its exhibit.
NASA will provide photos and updates about its participation in the International Astronautical Congress from its @NASAExhibit account on X.

Video: 00:01:20 Approximately 41 000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere.
Scientists at the Technical University of Denmark and the German Research Centre for Geosciences used data from ESA’s Swarm mission, along with other sources, to create a sounded visualisation of the Laschamp event. They mapped the movement of Earth’s magnetic field lines during the event and created a stereo sound version which is what you can hear in the video.
The soundscape was made using recordings of natural noises like wood creaking and rocks falling, blending them into familiar and strange, almost alien-like, sounds. The process of transforming the sounds with data is similar to composing music from a score.
Data from ESA’s Swarm constellation are being used to better understand how Earth’s magnetic field is generated. The satellites measure magnetic signals not only from the core, but also from the mantle, crust, oceans and up to the ionosphere and magnetosphere. These data are crucial for studying phenomena such as geomagnetic reversals and Earth’s internal dynamics.
The sound of Earth’s magnetic field, the first version of the magnetic field sonification produced with Swarm data, was originally played through a 32-speaker system set up in a public square in Copenhagen, with each speaker representing changes in the magnetic field at different places around the world over the past 100 000 years.
