In total eclipse of a star, New Horizons' future flyby target makes its presence known

Emily Lakdawalla • July 19, 2017

The team reported two weeks ago that the first attempts at observing 2014 MU69 were unsuccessful. But in their third try, on July 17, astronomers in Argentina saw the telltale sign of MU69's presence: a stellar wink.

When New Horizons' next target passed in front of a star, this scientist was watching from Argentina

In the second and final chapter of our series, we’ll explore what the rocket equation has to say about travel through the solar system, using the example of launching a rocket to Pluto.

Spaceflight in 2017, part 2: Robots beyond Earth orbit

Emily Lakdawalla • December 30, 2016 • 4

What's ahead for our intrepid space explorers in 2017? It'll be the end of Cassini, but not before the mission performs great science close to the rings. OSIRIS-REx will fly by Earth, and Chang'e 5 will launch to the Moon, as a host of other spacecraft continue their ongoing missions.

What's up in the solar system, November 2016 edition: Cassini takes a leap, ExoMars starts science, Long March 5 launch

Emily Lakdawalla • November 01, 2016 • 2

Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20 "F-ring" orbits. ExoMars will get two science orbits before beginning aerobraking. Long March 5 will have its first launch, while many Earth-observing missions, including Himawari-9 and GOES-R, will go up. But Juno science is on hold.

DPS/EPSC update on New Horizons at the Pluto system and beyond

What's up in the solar system, October 2016 edition: ExoMars arrives!

Emily Lakdawalla • October 04, 2016 • 2

ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.

What's up in the solar system, September 2016 edition: OSIRIS-REx launches, Rosetta ends

Emily Lakdawalla • August 31, 2016 • 1

The month of September begins with an annular solar eclipse visible from much of Africa on September 1. On or after September 8, we'll see OSIRIS-REx launch into a two-year cruise toward a rendezvous with asteroid Bennu. But September will close, sadly, with the end of the wonderful Rosetta mission.
