A Chinese communications satellite heading for geostationary orbit more than 22,000 miles over the equator lifted off Thursday from the Xichang space base in southwestern China aboard a Long March 3B rocket on the first space launch of 2019.

SpaceX’s next Falcon 9 rocket arrived at Kennedy Space Center’s pad 39A on Thursday for a hold-down engine firing ahead of launch next week with the U.S. Air Force’s X-37B spaceplane. The brief engine ignition occurred at 4:30 p.m. EDT (2030 GMT).

Ground observations of the New Horizons spacecraft’s next target last month revealed the distant object, lurking in the outer solar system more than four billion miles from Earth, might have an unconventional elongated shape, or even consist of two icy bodies orbiting one another in an age-old cosmic dance.
