The International Space Station, Mars 2020, the James Webb Space Telescope and the Joint Polar Satellite System are some of the projects that the National Aeronautics and Space Administration is working on, as of 2015. Some NASA projects are designed to explore outer space while others are focused on a better understanding of forces that affect Earth.
Maintaining and supplying the International Space Station is a substantial undertaking being handled primarily by NASA. The ISS mission to bring together global resources and personnel for the space research laboratory is a landmark task for the agency.
Currently in the mission design and landing site planning stages, the Mars 2020 program is preparing for the next rover landing to explore Earth's closest neighbor. New technology including a flying sky crane to land the new rover on Mars is on the drawing board. The project is operating on a strict timetable to achieve an optimal launch window for the shortest trip to Mars.
The James Webb Space Telescope is designed to find the origins of the universe. Its equipment is designed to probe for the first light generated from the Big Bang and the first galaxies formed in the process.
NASA is working with the National Oceanic and Atmospheric Association on the Joint Polar Satellite System project, which is a non-geosynchronous, polar orbiting set of environmental satellites. The JPSS can more effectively monitor, detect and predict weather and climate as well as its effects on the Earth's oceans and coastal regions.
