Because they're expensive and/or seem to have not enough chance to succeed.
Nobody knows but NASA might know in the future.
Yes, NASA continually experiments with various forms of hydroponics so that they could be possibly included in some future space exploration projects. These projects have two benefits, production of food and the conversion of carbon dioxide back into breathable oxygen.
In the future, NASA plans to focus on ambitious projects, including the Artemis program, which aims to return humans to the Moon by the mid-2020s and establish a sustainable presence there. The agency is also working on the Mars Sample Return mission, which seeks to bring samples from the Martian surface back to Earth. Additionally, NASA will continue to advance its Earth science missions and develop technologies for future deep-space exploration, including crewed missions to Mars in the 2030s. Overall, NASA's future endeavors will emphasize international collaboration, scientific discovery, and technology innovation.

The goal is to get pictures of mars to find out more about it .NASA is looking at mars for a future home.
One way to introduce your projects to NASA is to participate in their challenges or competitions, such as the NASA Innovative Advanced Concepts program or the NASA iTech initiative. You can also attend industry conferences and workshops where NASA representatives are present to showcase your projects and network with potential collaborators within the organization. Another option is to submit a proposal in response to NASA's open solicitations or calls for proposals related to your area of expertise.
NASA is the acronym for the US's National Aeronautics and Space Administration. While the former Soviet Union made great inroads early on regarding space exploration, NASA has leaped ahead and by its trips to the moon, sending a probe to Mars, and planning at some point in time a manned mission to that planet. History has now changed as it can be foreseen that manned space travel is a real possibility in the future. This will be a remarkable set of events pioneered by NASA.
Not in the near future. It is inevitable that earth will be hit eventually, but a significant impact might not occur for thousands, even millions of years. Currently, NASA does not know of any objects that have a significant risk of impacting earth.
All the Nasa projects would be useless,then all the investment for Nasa projects on mars would be used to help people on earth out of hunger .
According to NASA, future helicopters may be probably made of shape-changing materials.
