In less than 3 days, Japan's Hayabusa-2 probe will touch asteroid Ryugu and grab samples from the surface. Here's how it will go: hayabusa2.jaxa.jp/en/enjoy/mater…
Touching down on a tiny asteroid is a delicate operation. It requires precision navigation using a set of special target markers (TM in this diagram).
Part of Hayabusa-2's sample-collection process involves firing a bullet into an asteroid! hayabusa2.jaxa.jp/en/topics/2019…

Here are 180 factual, fully-sourced examples of the impact Brexit is already having on the UK. Jobs going, investment drying up, companies moving assets to the EU, or redomiciling. All happening as Government burns through £billions chasing a no deal Brexit it doesn't have to.
The Government has spent £4.2 billion pounds on Brexit preparations (£2.2 billion in previous Budgets, plus an additional £2 billion in the most recent Budget.) 1/180

EU citizens will be forced to register to stay in the UK after Brexit (deadline is June 2021). The system, which cost the Government £175 million, will have to cope with over 3,500,000 applications, or several thousand a day on average. 2/180

Today in pulp I'm looking back at one of #Japan's greatest science fiction magazines: Hayakawa S-F! #FridayFeeling
Esu-Efu Magajin (S-F Magazine) was first published in February 1960 by Hayakawa Shobō publishing, and has gone on to shape both Japanese SF and champion Japanese authors.
Science fiction had been reasonably popular in Japan before the war, but it was in the mid-1950s that specialist story magazines, such as Takumi Shibano's subscription fanzine Uchūjin (Cosmic Dust) began to appear.

[MASCOT] The MASCOT separation operation has begun! Preparations for the descent of Hayabusa2 towards asteroid Ryugu began in September 30, but today (October 2) the spacecraft will begin to descend. #asteroidlanding
[MASCOT] October 2 at 12:14 JST: The spacecraft was confirmed to have started the descent from the home position (altitude of about 20km) as planned. #AsteroidLanding
[MASCOT] During the MASCOT deployment operation, images taken for navigation with the Optical Navigation Camera - Wide angle (ONC-W1) will be replayed in real time. Come and see our gallery! #asteroidlanding hayabusa2.jaxa.jp/en/galleries/o…

On September 23, 2018, We were able to confirm that Rover-1B hopped! [1/6]

(1/3) #JAXA's hopping "robots will take advantage of [Ryugu the asteroid’s] low gravity, jumping around on the surface – soaring as high as 15 metres (49ft) and staying in the air for as long as 15 minutes – to survey the asteroid’s physical features."
theguardian.com/science/2018/s…
(2/3) Hayabusa2 (Japanese for falcon) is about the size of a large fridge and equipped with solar panels, and is the successor to JAXA’s first asteroid explorer, Hayabusa, which failed to land a rover on another asteroid in a similar mission in 2005. via @nycjim
(3/3) "In October, the Hayabusa2 probe will deploy an 'impactor' that will explode above the asteroid, shooting a 2kg copper missile to blast a small crater into the surface."
