NASA Administrator Bill Nelson, U.S. Environmental Protection Agency (EPA) Administrator Michael Regan, and other United States government leaders unveiled the U.S. Greenhouse Gas Center Monday during the 28th annual United Nations Climate Conference (COP28).

“NASA data is essential to making the changes needed on the ground to protect our climate. The U.S. Greenhouse Gas Center is another way the Biden-Harris Administration is working to make critical data available to more people – from scientists running data analyses, to government officials making decisions on climate policy, to members of the public who want to understand how climate change will affect them,” said Nelson. “We’re bringing space to Earth to benefit communities across the country.”

The U.S. Greenhouse Gas Center will serve as a hub for collaboration between agencies across the U.S. government as well as non-profit and private sector partners. Data, information, and computer models from observations from the International Space Station, various satellite and airborne missions, and ground stations are available online.  

As the lead implementing agency of the center, NASA partnered with the EPA, National Institute of Standards and Technology, and National Oceanic and Atmospheric Administration. Science experts from each of these U.S. federal agencies curated this catalog of greenhouse gas datasets and analysis tools.  

“A goal of the U.S. Greenhouse Gas Center is to accelerate the collaborative use of Earth science data,” said Argyro Kavvada, center program manager at NASA Headquarters in Washington. “We’re working to get the right data into the hands of people who can use it to manage and track greenhouse gas emissions.”

The center’s data catalog includes a curated collection of data sets that provide insights into greenhouse gas sources, sinks, emissions, and fluxes. Initial information in the center website is focused on three areas: 

  • Estimates of greenhouse gas emissions from human activities 
  • Naturally occurring greenhouse gas sources and sinks on land and in the ocean. 
  • Large methane emission event identification and quantification, leveraging aircraft and space-based data   

An example of a dataset is the methane gas information detected by NASA’s EMIT (Earth Surface Mineral Dust Source Investigation) mission. Located on the International Space Station, EMIT is an imaging spectrometer that measures light in visible and infrared wavelengths and thus can measure release of methane on Earth. 

Built on open-source principles, the U.S. Greenhouse Gas Center’s datasets, related algorithms, and supporting code are fully open sourced. This allows anyone to test the data, algorithms, and results. The center also includes user support and an analysis hub for users to perform advanced data analysis with computational resources and an interactive, visual interface for storytelling. NASA encourages feedback and ideas on the center’s evolution. The center is part of a broader administration effort to enhance greenhouse gas information, outlined in the recently released National Strategy to Advance an Integrated U.S. Greenhouse Gas Measurement, Monitoring, and Information System.

Unlocking the Next Frontier: Odysseus Lunar Lander’s Historic Mission

“Odysseus lunar lander aims to make history with first U.S. spacecraft touchdown on moon in 50 years. A testament to human ambition and innovation.”

Published

on

In the vast expanse of space, where dreams of exploration meet the harsh realities of technology and finance, Thursday marks a potential landmark moment in the annals of space exploration. The Odysseus lunar lander, a testament to human ingenuity and perseverance, stands on the precipice of making history as it aims to achieve what no U.S.-made spacecraft has done in five decades: a controlled touchdown on the lunar surface.

After a breathtaking lift-off from Florida, Odysseus embarked on its journey towards the moon, capturing awe-inspiring images of our planet Earth along the way. Now, as it hurtles closer to its destination, the anticipation mounts for what could be the most perilous test yet – a soft landing on the moon’s surface.

Intuitive Machines, the pioneering force behind Odysseus, dares to tread where no private company has ventured before. If successful, this endeavor would mark the resurgence of American-made spacecraft landing on the moon since the final Apollo mission in 1972.

However, the road to lunar exploration is fraught with challenges, both technical and financial. While the Apollo program once commanded a budget exceeding 4% of all U.S. government spending, today’s NASA operates on a fraction of that, a mere 0.4%. To stretch resources further, NASA has turned to outsourcing robotic lunar landings to commercial entities like Intuitive Machines, aiming to achieve ambitious goals like the Artemis program’s lunar return with reduced costs.

But cost isn’t the only hurdle. The technical feat of landing a spacecraft precisely on a celestial body a quarter of a million miles away is akin to hitting a golf ball from New York to Los Angeles and landing it in a specific hole – a daunting task even with today’s advanced technology. Compounding the challenge is the time delay of roughly three seconds for signals to travel between Earth and the moon, leaving little room for error during critical maneuvers.

Moreover, the legacy of Apollo-era expertise has waned over the decades, leaving a gap that new technology alone cannot bridge. As Dr. Scott Pace of George Washington University’s Space Policy Institute aptly notes, “These are people doing it for the first time, and there’s no substitute for that experience.”

Yet, amidst these challenges, there’s an undeniable sense of optimism and determination. As Lisa Altemus of Intuitive Machines emphasizes, success in lunar exploration requires collective resilience, collaboration, and a willingness to learn from failures. It heralds not just a scientific achievement but the dawn of a new era – an emerging lunar economy where the moon’s resources could unlock boundless opportunities for humanity.

If Odysseus achieves its mission, it will not only mark the first U.S. spacecraft landing on the moon in half a century but also pave the way for future lunar endeavors, including the exploration of the moon’s south pole, a region rich in potential resources like ice and water.

As we stand on the brink of this historic moment, let us marvel at the audacity of human ambition, the tenacity of scientific endeavor, and the boundless possibilities that lie beyond Earth’s confines. The journey to the moon may be fraught with challenges, but with each step, we inch closer to unlocking the mysteries of our celestial neighbor and forging a new chapter in the saga of space exploration.

New NASA Mission will Study Ultraviolet Sky, Stars, Stellar Explosions

Published

on

WASHINGTON /PRNewswire/ — As NASA explores the unknown in air and space, a new mission to survey ultraviolet light across the entire sky will provide the agency with more insight into how galaxies and stars evolve. The space telescope, called UVEX (UltraViolet EXplorer), is targeted to launch in 2030 as NASA’s next Astrophysics Medium-Class Explorer mission.

In addition to conducting a highly sensitive all-sky survey, UVEX will be able to quickly point toward sources of ultraviolet light in the universe. This will enable it to capture the explosions that follow bursts of gravitational waves caused by merging neutron stars. The telescope also will carry an ultraviolet spectrograph to study stellar explosions and massive stars.

“NASA’s UVEX will help us better understand the nature of both nearby and distant galaxies, as well as follow up on dynamic events in our changing universe,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “This mission will bring key capabilities in near-and far-ultraviolet light to our fleet of space telescopes, delivering a wealth of survey data that will open new avenues in exploring the secrets of the cosmos.”

The telescope’s ultraviolet survey will complement data from other missions conducting wide surveys in this decade, including the Euclid mission led by ESA (European Space Agency) with NASA contributions, and NASA’s Nancy Grace Roman Space Telescope, set to launch by May 2027. Together, these missions will help create a modern, multi-wavelength map of our universe.

“With the innovative new UVEX mission joining our portfolio, we will gain an important legacy archive of data that will be of lasting value to the science community,” said Mark Clampin, director of the Astrophysics Division at NASA Headquarters. “This new telescope will contribute to our understanding of the universe across multiple wavelengths and address one of the major priorities in Astrophysics today: studying fleeting changes in the cosmos.”

NASA selected the UVEX Medium-Class Explorer concept to continue into development after detailed review of two Medium-Class Explorer and two Mission of Opportunity concept proposals by a panel of scientists and engineers, and after evaluation based on NASA’s current astrophysics portfolio coupled with available resources. The UVEX mission was selected for a two-year mission and will cost approximately $300 million, not including launch costs.

The mission’s principal investigator is Fiona Harrison at Caltech in Pasadena, California. Other institutions involved in the mission include University of California at Berkeley, Northrop Grumman, and Space Dynamics Laboratory.

The Explorers Program is the oldest continuous NASA program. The program is designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the agency’s astrophysics and heliophysics programs.

Since the launch of Explorer 1 in 1958, which discovered the Earth’s radiation belts, the Explorers Program has launched more than 90 missions, including the Uhuru and Cosmic Background Explorer missions that led to Nobel prizes for their investigators.

The program is managed by NASA’s Goddard Space Flight Center for the Science Mission Directorate, which conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe.
