Lifespan is basically what happens in life; aging patterns, life expectancy is how long an average person is expected to live. Lifespan hasn't changed recently (if it had, we would assume things like menopause happening later, etc.. happening), but life expectancy has increased rapidly due to better technologies etc
Lifespan is the expression of the biological aging pattern of the species (how rapidly and at what average age different organ systems decline in functionality in a given species). Life expectancy is the average age that individuals in a species tend to die. Life expectancy has changed the most in recent years.
