Commander Chris Hadfield says goodbye to the International Space Station through the medium of David Bowie

Highest music video since Snoop Dogg's last one.

Commander Chris Hadfield – the Canadian astronaut who has spent the last five months acting as a sort of ambassador from space to the internet, tweeting, tumbling and YouTubing the wonders of zero-g living – is preparing to leave the International Space Station. At eight minutes past midnight tonight (UK time), the Soyuz capsule returning him, US astronaut Tom Marshburn and Russian cosmonaut Roman Romanenko to earth will undock, and two and a half hours later it will begin its descent towards the Kazakhstani steppes where it is planned to land. If everything goes according to the plan, it will touch down at 3:31am on Tuesday morning.

There's a lot for Commander Hadfield to do between now and then, which is why his goodbye video went up 24 hours in advance. Written by David Bowie, performed (largely) in space by Commander Chris Hadfield, it's a Space Oddity:

Hadfield is a mean musician; here's his (earthbound) performance of Ride On from earlier this year, and here's him playing his low-weight guitar on the Russian space-station Mir in 1995. If you need something to boost you on an overcast Monday morning, try watching the rest of his videos from space.

Videos from space. Can't say that enough, really.

Goldsmiths diversity officer Bahar Mustafa receives court summons in wake of “#KillAllWhiteMen” outcry

Mustafa will answer charges of "threatening" and "offensive/ indecent/ obscene/ menacing" communications.

In May this year, Bahar Mustafa, then diversity officer at Goldsmiths, University of London, posted a Facebook message requesting that men and white people not attend a BME Women and non-binary event. There was an immediate backlash from those also enraged by the fact that Mustafa allegedly used the hashtag #KillAllWhiteMen on social media. 

Today, Mustafa received a court summons from the Metropolitan Police to answer two charges, both of which come under the Communications Act 2003. The first is for sending a "letter/communication/article conveying a threatening message"; the second for "sending by public communication network an offensive/ indecent/ obsecene/ menacing message/ matter".

It isn't clear what communciation either charge relates to - one seems to refer to something sent in private, while the use of "public communication network" in the second implies that it took place on social media. The Met's press release states that both communciations took place between 10 November 2014 and 31 May 2015, a very broad timescale considering the uproar around Mustafa's social media posts took place in May. 

We approached the Met to ask which communications the summons refers to, but a spokesperson said that no more information could be released at this time. Mustafa will appear at Bromley Magistrates' Court on 5 November.
