Now more than two years outbound from its historic encounter with Pluto, NASA’s New Horizons spacecraft is on target for a fleeting flyby less than 2,200 miles from 2014 MU69, an icy, city-sized world set to become the most distant object ever visited, just after midnight Jan. 1, 2019. Scientists now say the probe may be able to pursue another destination some time in the 2020s.

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.

NASA’s Juno spacecraft to remain in current orbit around Jupiter

Concerns about the health of the Juno spacecraft’s main engine have compelled NASA managers to keep the research probe in its current arcing, high-altitude orbit around Jupiter, a decision that will delay the full science return from the $1.1 billion mission but should still allow it to meet all predetermined objectives.

NASA’s Juno spacecraft made a high-speed pass less than 3,000 miles over Jupiter’s turbulent clouds Thursday, taking dozens of pictures, measuring radiation and plasma waves, and peering deep inside the planet’s atmosphere, but officials still have not cleared the orbiter’s main engine for a planned maneuver to position the probe for improved science observations.
