Before we could see the shape of Ryugu, what did the Hayabusa2 team expect? From the realistic to the horrifying to the edible, these were our best guesses! http://www.hayabusa2.jaxa.jp/topics/20180626_e/index_e.html …

«7-й корректирующий манёвр траектории», написанный ранее ранее, был ошибкой. Следует читать «9-й корректирующий манёвр траектории». Приносим извинения.

Our 9th Trajectory Control Manoeuvre (TCM09) for optical navigation was made on June 26 at ~10:10-10:20JST. Thrusters changed the velocity by ~0.8cm/s (-x), 0.3cm/s (+y), 10cm/s (+z). Ryugu to Hayabusa2 distance was ~23km & the speed towards the asteroid after TCM09 was ~2cm/s.

Looks like Hayabusa-2 has reached the 20 km rendezvous point off Ryugu.
Congrats @jaxa_en

 
Через 1302 дня после запуска зонд Хаябуса-2 прибыл к астероиду Рюгю. Съёмка с расстояния около 22 км.

ついに、☆リュウグウ☆に到着したよ
打ち上がってから1302日。
長かったけど、あっと言う間という感じも。
これがリュウグウ(約22kmから撮影)
これからが探査の本番だね。

Hayabusa2 Rendezvous with Ryugu
June 27, 2018 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)
JAXA confirmed Hayabusa2, JAXA's asteroid explorer rendezvoused with Ryugu, the target asteroid.

On June 27, 2018, JAXA operated Hayabusa2 chemical propulsion thrusters for the spacecraft's orbit control.*
The confirmation of the Hayabusa2 rendezvous made at 9:35 a.m. (Japan Standard Time, JST) is based on the following data analyses;
  • The thruster operation of Hayabusa2 occurred nominally
  • The distance between Hayabusa2 and Ryugu is approximately 20 kilometers
  • Hayabusa2 is able to maintain a constant distance to asteroid Ryugu
  • The status of Hayabusa2 is normal
From this point, we are planning to conduct exploratory activities in the vicinity of the asteroid, including scientific observation of asteroid Ryugu and surveying the asteroid for sample collection.

*Hayabusa2 operation hours: 7:00 a.m. (JST) through 3:00 p.m. (JST), June 27. The thruster operation was pre-programmed in the event sequence earlier on the day and the command was automatically executed.

Our 10th Trajectory Control Manoeuvre (TCM10) for optical navigation was made on June 27, 2018. This is our “Arrival TCM”! Thrusters adjusted the spacecraft velocity between ~09:30 - 09:35 JST by 0.7 cm/s (x) and 2.8 cm/s (z). (1/2)

The distance between Hayabusa2 and Ryugu at the time of the TCM was 20.7 km and the relative speed after TCM10 was less than about 0.01 m/s (1 cm/s). Finally we have arrived at Ryugu. (2/2)

Japanese spacecraft reaches asteroid after three-and-a-half-year journey
June 28, 2018 | Stephen Clark

Japan’s robotic Hayabusa 2 spacecraft arrived Wednesday at asteroid Ryugu, a diamond-shaped object more than a half-mile wide where the probe will attempt a brief landing later this year to collect rock specimens for return to Earth.

After creeping up to the asteroid at an ever-slowing pace, thrusters on the Hayabusa 2 spacecraft stopped its approach Wednesday at a distance of about 12 miles, or 20 kilometers, according to the Japan Aerospace Exploration Agency.

The milestone marked the conclusion of a three-and-a-half-year voyage spanning nearly 2 billion miles (3.2 billion kilometers) since Hayabusa 2’s launch fr om southern Japan on an H-2A rocket in December 2014.

The space probe and asteroid Ryugu, seen up-close for the first time, are currently located roughly 177 million miles (285 million kilometers) from Earth. Under remote control from engineers and scientists in Japan, Hayabusa 2 will spend the next few weeks surveying Ryugu, moving closer in a sequence of maneuvers to obtain higher-resolution imagery and data on the asteroid’s gravity field.
