One of the most well known is probably Velcro or Hook And Loop. The astronauts in the lunar lander had this on their boots to hold them to the floor in the low gravity. Additionally, advances in solar cells, spurred by the space program, has led to a thriving solar industry on Earth. Many medical advances can be attributed to the space program, such as the use of the MRI and CAT scanning machines, which use imaging technology invented by NASA's JPL division.
There are many but here are a few, smoke detectors.
The pocket compass is most useful for those adventurous people who do mountain or forest exploration, mountain climbing, hiking or when one is lost in the dessert.
Researching how earth life act in the space conditions. Manufacturing in the absence of gravity can also help some crystals to grow more evenly. No other immediate useful goals.
I'm not sure about all of the inventions but some of the most useful ones include the smoke detector (originally used to detect toxic vapors), satelite TV dishes (developed to reduce noise interference), various fire proof materials and the development of medical internal imaging and of course velcro. Hope it helps.
