  Low Earth orbit Satellite Networks (LSNs) have been advocated as a key
infrastructure for truly global coverage in the forthcoming 6G. This paper
presents our initial measurement results and observations on the end-to-end
network characteristics of Starlink, arguably the largest LSN constellation to
date. Our findings confirm that LSNs are a promising solution towards
ubiquitous Internet coverage over the Earth; yet, we also find that the users
of Starlink experience much more dynamics in throughput and latency than
terrestrial network users, and even frequent outages. Its user experiences are
heavily affected by environmental factors such as terrain, solar storms, rain,
clouds, and temperature, so is the power consumption. We further analyze
Starlink's current bent-pipe relay strategy and its limits, particularly for
cross-ocean routes. We have also explored its mobility and portability
potentials, and extended our experiments from urban cities to wild remote areas
that are facing distinct practical and cultural challenges.
