There are thousands of satellites currently orbiting the Earth. The exact number can vary, as new satellites are launched and old ones are decommissioned regularly.
The exact number of functioning sattelites is hard to know because a lot of satellites are classified military statellits. There are currently ove 3000 satellites in orbit a lot of which are no longer functioning. The number changes rapidly as new ones are launched all the time
Scientists at NASA do various things. The tasks are all space or physics related. NASA is US's Space Program. They launched satellites like Swift,skylab ect. NASA scientists test zero G, jet propulsion, sample space rocks ect. Space Shuttles and Mars Rovers are one of NASA's achievements.
The NASA project following Project Mercury was called Project Gemini. It served as a bridge between Mercury and Apollo, testing new technologies and techniques needed for the later moon-landing missions.
