Questions & Answers

Q: What are some of the major contributions NASA has made to Earth science?

NASA has a unique perspective of studying Earth from space, allowing scientists to understand the interactions between different components of the Earth's system such as land, water, ice, and atmosphere. The agency is studying the effects of climate change, rising sea levels, and the role of greenhouse gases to improve our understanding of Earth's complex systems.

Q: How is the ozone layer healing according to NASA's satellite data and models?

NASA has been at the forefront of studying the ozone layer for decades. Following the Montreal Protocol, which aimed to limit the production and use of ozone-depleting substances, NASA's data shows that the ozone layer is healing. However, continued efforts are needed to ensure nations comply with the protocol and mitigate any challenges.

Q: How is NASA's x57 Maxwell aircraft powered?

The x57 Maxwell is powered fully by electricity using 14 electric motors along the aircraft. This all-electric technology aims to make flying cleaner, quieter, and more sustainable. The motors are lightweight and positioned in innovative ways, such as at the wingtips, to reduce aircraft drag and improve performance.

Q: How does NASA's Oscar project convert trash into usable resources in space?

The Oscar project converts solid trash found in space missions into gases that can be used for venting off spacecraft or as fuels. By converting the trash, it reduces the volume of waste and explores the potential for more sustainable human presence in space. The technologies developed for Oscar could have applications for waste management on Earth as well.
