Timeline for Akatsuki's second attempt at orbit insertion

Emily Lakdawalla • December 04, 2015 • 5

This is it: Akatsuki's final chance at Venus orbit insertion. The rocket firing should begin on December 7 at 08:51 Japan time (December 6 23:51 UT / 15:51 PST) and last for 20 minutes. It will take two days for JAXA to determine whether the orbit has been changed enough for Akatsuki to stay at Venus.

Back from the Brink: Akatsuki Returns to Venus

Ralph Lorenz • December 04, 2015 • 2

Perhaps forgotten by the general public in the West, a long-lost spacecraft is set to enter orbit around our sister planet in December, picking up where ESA’s Venus Express left off when its operations ended last year.

Two JAXA mission updates: Akatsuki Venus orbit entry and PROCYON Earth flyby coming up!

Emily Lakdawalla • November 19, 2015

Akatsuki is finally approaching its second attempt to enter Venus orbit, on December 7; let's all wish JAXA the best of luck! And PROCYON, whose ion engines have failed, is still an otherwise perfectly functional spacecraft that is taking photos of Earth and the Moon as it approaches for a flyby.

What's up in solar system exploration: August 2015 edition

I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.

Two more brief mission updates: Philae makes contact; Akatsuki to perform course correction

Emily Lakdawalla • July 10, 2015 • 6

As a followup to yesterday's post about Dawn, Juno, and OSIRIS-REx, I have updates on two more missions. With this post, I hope to have cleared the decks so that I can focus on Pluto for the next week!

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

Emily Lakdawalla • February 09, 2015 • 2

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.

Short updates on Akatsuki and Chang'e missions

Emily Lakdawalla • January 06, 2015 • 1

A few recent newspaper articles provide some updates on the status of Japan's Venus mission, Akatsuki, and the service module of China's Chang'e 5 test vehicle, Xiaofei. In brief: Akatsuki still plans to attempt to enter orbit in December of this year, while Chang'e 5 T1 is headed to lunar orbit. Meanwhile, the Chang'e 3 mission has released an interesting image of M101, the Pinwheel Galaxy.

Intro Astronomy Class 4: Eclipses, Mercury, Venus-Earth-Mars Atmospheres, Venus

Bruce Betts • February 28, 2014

This video of class 4 of Bruce Betts' Introduction to Planetary Science and Astronomy class discusses eclipses, Mercury, Venus, and a comparison of the atmospheres of Venus, Earth, and Mars.

What's up in planetary missions in 2014

Emily Lakdawalla • December 31, 2013 • 4

With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.

What's Up in the Solar System in July 2012

Emily Lakdawalla • July 02, 2012

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.
