What's up in solar system exploration: April 2016 edition

This month (actually, today), Cassini had a relatively close flyby of Titan, and New Horizons will observe a very distant Kuiper belt object named 1994 JR1. Akatsuki has just fine-tuned its orbit around Venus, and Hayabusa2 has begun an 800-hour ion engine thrusting phase to steer it toward near-Earth asteroid Ryugu.

How do you pronounce "Ryugu?"

With some help from astronomer Elizabeth Tasker and a group of astronomy graduate students from the University of Hokkaido, I learn how.

Hayabusa2's target asteroid has a name!

JAXA announced today the results of the naming contest for Hayabusa2. The target of the sample-return mission, formerly known as 1999 JU3 and still numbered 162173, is now named 162173 Ryugu.

Name Hayabusa2's asteroid target!

Have you ever wanted to name an asteroid? JAXA is offering the opportunity to name Hayabusa2's target asteroid, 1999 JU3 to the public through a contest that runs through August 31.

PROCYON update: Asteroid 2000 DP107 target selected, ion engine stopped

PROCYON (PRoximate Object Close flYby with Optical Navigation) is a microsatellite that launched on December 3 as a secondary payload with Hayabusa2. The mission has now selected their asteroid flyby target -- a binary asteroid named 2000 DP107 -- but is reporting a problem with their ion engines.

A new mission for Akatsuki, and status updates for Hayabusa2 and Chang'e

Brief updates on four ongoing missions: JAXA's Akatsuki and Hayabusa2, and China's Chang'e 3 and Chang'e 5 test vehicle. JAXA has articulated the new science plan for Akatsuki. Hayabusa2's ion engines have checked out successfully. The Yutu rover is still alive on the Moon, and Chang'e 5 test vehicle has successfully tested crucial rendezvous operations in lunar orbit.

Hayabusa2 launches toward asteroid rendezvous

Hayabusa2 successfully launched on December 3, 2014 at 04:22 UTC, and embarked on its interplanetary journey about two hours later. During the launch, cameras captured video of the spacecraft fairing separation.

Hayabusa2 is about to launch! [UPDATED]

Hayabusa2's H-IIA rocket has just reached its launchpad! Japan's next asteroid sample return mission was supposed to launch this weekend, but weather has not been good at the Tanegashima launch site and it has been delayed four days already. If the weather holds, it will launch December 3 at 04:22 UT (13:22 JST, or December 2 at 20:22, PT). UPDATED to add links to live webcasts.
