★ Hayabusa2 status (the week of 2018.7.16) ★

Last week we performed short-term operations at an altitude of about 6 km. This allowed closer observations of Ryugu in more detail and the data downlink is happening now. While usual operations are “BOX-A”, these operations at a different maintenance altitude are called “BOX-C” operations. While we did not keep the order, we will do “BOX-B” operations. Do look forward to these!

Last week, Hayabusa2 descended to make a closer inspection of asteroid Ryugu. Take a look at what Ryugu's surface looks like at just 6km away!

МОСКВА, 26 июл – РИА Новости. Зонд "Хаябуса-2" получил первые сверхчеткие фотографии поверхности астероида Рюгю, сблизившись с ним на расстояние в шесть километров. Снимки и первые результаты наблюдений были представлены на сайте JAXA.

В момент максимального сближения зонд и Рюгю разделяло всего шесть километров пустоты, что позволило ученым повысить четкость снимков примерно в 3,4 раза и рассмотреть новые детали его рельефа. К примеру, оказалось, что поверхность астероида покрыта необычно большим числом крупных "булыжников", чье происхождение пока остается загадкой для планетологов.

Ryugu - a ‘diamond’ in space

  • Asteroid Ryugu was imaged for the first time fr om a distance of just six kilometres
  • Among other things, the images serve as preparation for the landing site selection. The MASCOT lander, which was developed and built at DLR, is due to land on the asteroid in October.
  • Focus: Space, Exploration

As the Japanese Hayabusa2 spacecraft closes in on asteroid Ryugu, more details become visible to the planetary scientists. On 20 July 2018, from a distance of just six kilometres, the spacecraft’s Optical Navigation Camera - Telescopic (ONC-T) acquired an image of the asteroid’s surface, with its largest crater. "We see that the entire surface of Ryugu is strewn with large boulders – we have not yet seen this on an asteroid," says Ralf Jaumann, a planetary scientist at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and Principal Investigator for the MASCOT (Mobile Asteroid Surface Scout) lander aboard the Japanese spacecraft. It is anticipated that on 3 October 2018, MASCOT will land on Ryugu and examine the asteroid surface using four instruments.

★ Hayabusa2 status(the week of 2018.7.23)★

This week, we returned from the 6km altitude “BOX-C” to “BOX-A”, staying at an altitude of 20km±1km while images taken at BOX-C were downloaded. The images released on July 25 showed a detailed view of the unevenness of Ryugu’s surface. Meanwhile, we conducted a test on the laser distance measurer, LIDAR, in preparation for the “Middle Altitude Observation Operation”, in which the spacecraft will descend to hover at a 5km altitude and then perform the “Gravity Measurement Descent Operation” which decreases the altitude to just 1km. We are ready!

A spectroscopic image of Ryugu at high resolution

The article posted on July 25, 2018 introduced an image captured when Hayabusa2 descended towards asteroid Ryugu, reaching an altitude of just 6km above the surface. At this time, we also took photographs in which the viewing angle towards the asteroid gradually changed as Ryugu rotated. Using the previously published image and a second image fr om a slightly different angle (see the referlence at the end of this page), we created a composite frame where the two photographs are superimposed in red and blue (Figure 1). If you view this image with red-blue stereoscopic glasses (right eye should be blue, left eye is red), you can see this high resolution image of the asteroid in three-dimensions and explore the shape and topography of this small world.

Hayabusa2 Project
HAYABUSA2@JAXA‏ @haya2e_jaxa 8 ч. назад

[MAltOp] Today, we are beginning our Medium Altitude Operation, descending to ~5km from Ryugu’s surface. Currently, the Goldstone Station is being used for communication with Hayabusa2. @haya2_jaxa is live tweeting our progress & the English account will follow with a small delay
HAYABUSA2@JAXA‏ @haya2e_jaxa 8 ч. назад

[MAltOp] 9:35am was “Gate1”: the time when we judge if we can begin with the descent operation. After checking the status of both the spacecraft and ground-based systems, no hindrance was found to starting the descent. The Medium Altitude Operation is “Go”!

[MAltOp] At 10:38 JST we confirmed that Hayabusa2 had started the descent. The starting altitude was about 20 km and the descent speed was 40 cm/s.

[MAltOp] Hayabusa2’s wide-angle optical navigation camera (ONC-W1) snapped this photograph of Ryugu for navigation at 08:00 JST on August 1, 2018.

[MAltOp] At around 10:00 JST on August 1, 2018, Hayabusa2 took this image for navigation using the onboard wide-angle navigation camera (ONC-W1).

[MAltOp] At 18:00 JST (09:00 UTC) the ground operation station used to communicate with the spacecraft was handed over from JAXA’s Usuda Deep Space Center to DSN Madrid.

[MAltOp] At 20:32 JST we reached "Gate 2 (target altitude reached)": the checkpoint near the 5km target altitude for observations. We have confirmed the descent of Hayabusa2 has stopped. The navigation guidance state and the state of the spacecraft is normal.
Замечательное достижение японцев.
Теперь они по заказам корпораций смогут доставлять пробы любых астероидов
, на которых есть платина, редкие изотопы и т.д. на околоземную орбиту, к международной космической станции или на землю.
