No-one's watching? :hmm:
Hayabusa 2 is now in low Earth orbit! One orbit away from a second burn that puts it away from Earth.

I was! It was just awfully early in The Netherlands :lol:
Great launch (beautiful rocket!) and congratulations to JAXA

The launch takes place around 1:09:40 on the broadcast. Here's a direct link, starting at T-10, for convenience.

A Hatsune Miku song meant to commemorate the mission (even though it means falcon instead of phoenix, it still represents the "rebirth" theme)

PROCYON asteroid 2000 DP107 fly-by cancelled
Japanese interplanetary probe will not be able to fly by asteroid
05/09/2015
PROCYON (PRoximate Object Close flYby with Optical Navigation) is a 69 kg-class microsatellite developed by the University of Tokyo (UT) and JAXA/ISAS (Japan Aerospace Exploration Agency/Institute of Space and Astronautical Science). Launched with Hayabusa 2, its goal was to perform a close flyby of an asteroid in early 2016.
The on-board ion engine's high voltage power trouble was of the most problematic. As the situation was not resolved end of April 2015, the planned Earth fly-by on 3 December 2015 and the asteroid 2000 DP107 fly-by on 12 May 2016 were abandoned.

Ryugu Detected!
Nearly 3 years later...
Target found!
On February 26, 2018, Hayabusa2 saw its destination —asteroid Ryugu— for the first time! The photographs were captured by the ONC-T (Optical Navigation Camera - Telescopic) onboard the spacecraft. Images were taken between noon JST on February 26th and 9:00am the following morning, with about 300 shots taken in total. Data for nine of these images were transmitted from the spacecraft on February 27th, allowing us to confirm that Ryugu had indeed been seen. The animation shows these nine consecutive frames.

{colsp=2}This is the series of nine pictures taken from about 12:00 (noon) to around 15:00 JST on February 26, 2018. The celestial body moving slightly from left to right near the centre of each frame is Ryugu. Objects that can only be seen momentarily as they appear and disappear between frames are image noise. The viewing angle of the photo is 0.8 deg. (Credit: JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, University of Aizu and AIST. )
Ryugu's brightneess from Hayabusa2 is about magnitude 9, which would be impossible to see with the naked eye but visible with the ONC-T. Looking at the image above, you can see how the position of the surrounding stars relative to Ryugu appears to change as Hayabusa2 moves towards the asteroid. The distance between Ryugu and Hayabusa2 when the images were taken is about 1.3 million km. Ryugu as seen from Hayabusa2 is in the direction of the constellation Pisces.
Ryugu was photographed when the Sun, Hayabusa2 and Ryugu were almost in a line. This configuration can be seen in the figure below, which shows a snapshot of the header from the Hayabusa2 website on February 26, 2018, which continuously updates to show the position of Hayabusa2. If you were to stand on Ryugu, Hayabusa2 would be seen in the direction of the Sun.
The position of Hayabusa2 on February 26, 2018, captured from the diagram at the top of the mission website.
Hayabusa2 is currently using its ion engine to make adjustments to its course. This makes it difficult to alter the orientation of the spacecraft. However, at the alignment shown above, the ONC-T camera can image Ryugu without needing to make significant changes to the spacecraft's orientation. This made February 26th the perfect time to try and capture Ryugu's image with the ONC-T. From the data, Ryugu was observed to be exactly at the expected location based on Hayabusa2's estimated position. This tells us that Hayabusa2 is flying on the planned course.
"Now that we see Ryugu, the Hayabusa2 project has shifted to the final preparation stage for arrival at the asteroid. There are no problems with the route towards Ryugu or the performance of the spacecraft, and we will be proceeding with maximum thrust," explains Project Manager, Yuichi Tsuda.
The remaining images will be transmitted back to Earth from the spacecraft and allow us to further confirm the asteroid and spacecraft location. Although we can currently see Ryugu only as a point, it is very exciting for the whole project team to catch sight of the destination!
