2020s visions: We'll get flying cars just before becoming software-based people Each OneWeb satellite is roughly the size of a refrigerator and will climb to an altitude of 746 miles (1,200 kilometers). The service will be racing to start operations as SpaceX also ramps up launches of its Starlink satellites. SpaceX is aiming to have more than 1,600 of its own satellites in the sky this year -- all at a lower altitude than where OneWeb will operate initially -- with hopes of starting up its services for a limited number of customers as well. This rapid increase in satellites around the Earth has raised concerns from astronomers who've seen their observations of the universe disrupted over the past year by trains of highly reflective Starlink satellites. UFO sightings are also up thanks to the increase in orbital traffic. At a recent American Astronomical Society meeting in Hawaii, leaders from the astronomical community said they've been in discussions with both OneWeb and SpaceX to address the problem. Meanwhile, the launches continue. The third OneWeb launch is set to take place sometime in the coming weeks. Originally published Feb. 6, 10:08 a.m. PT.
