Distance from earth to gps satellite? Navigation satellites move around Earth at an altitude of about  1,243 miles to 22, 223 miles and at about the same speed of  rotation. These satellites are in what is calle â¦ d Medium-Earth  orbits (MEO).
When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil.
In the summer it is good to mulch the lawn (don't vacuum up the grass) so that you can spend less on water. 8. Aerate your lawn at least once in the spring and again in the fall for a green lawn. The process of aeration makes small holes in the surface of your lawn, allowing water, nutrients and air access to the roots. The water will be less likely to evaporate, and there are generally lower winds. 2  Watering the grass in high wind can cause the grass to dry before the water penetrates the soil. 3  For a green lawn, water your grass until the water penetrates at least 6 inches (15.24 cm) deep into the soil.
