InSight spacecraft launched by NASA is scheduled to land on Mars on 26 Nov. it will explore interior sections of Mars using Seismic Investigations. Landing process on the surface of Mars is very difficult. However after several years of preparation, engineers developed InSight and sent it to Mars. Health and trajectory of InSight is being tracked continuously by NASA engineers. Additionally, Martian weather will also play key role for safe landing. They are observing Martian weather also so that in case of bad weather they can extend the landing process.
