@ProfBrianCox There's nothing political about these things, they're just guys who like to fight police officers. No placards, no demands. Just exploiting the situation.

Johnson and his coterie have never met people like this. I’m sure they thought they could wind them up a bit to borrow their votes in order to become PM / get brexit done / whatever / and then put them back in their box. I suspect he now knows it’s not that simple.

@mmealling It's the NASA culture of overtraining and over-rehearsal, designed to ensure every person in space supports a thousand jobs at home.

My wife is watching the Dragon docking with me and she is amazed & frustrated at how long it takes to open a door.

@John_Gardi G7 or its variants was always conceived as the core group of civilized countries. It's right to exclude the USA from that.

@SpaceMoh @unknownsymmetry @AliKhorshidi94 @fazadotir @NASA @timmermansr @spaceagenda @SpaceX @elonmusk @hamed_hamedian Wow! Nailed the landing. Practice makes perfect, I guess.

@AliKhorshidi94 @fazadotir @NASA @timmermansr @spaceagenda @SpaceX @elonmusk @hamed_hamedian It was worth it!

@AwesomeAstroPod Also, there don't seem to be proper equal-volume joints on the suits. If they lose pressure, the people will be splayed out like starfish, unable to do anything. Suits just for show?

The launch is cool. The suits are not. They look like kids going to a fancy dress in wellies.

@SkinnerPm Ed McBain forever!

I would be forever grateful for any recommendations on detective or police mysteries or thrillers.

@unrocket Thanks Paul, that is great to hear. Please post anything you find controversial!

@RichardFPenn I just found your steps to space series, I've read 1,2 will start 3 in the next few days. All in all good engineer stories....

@Nick_Stevens_Gr Usually, big ships have low thrust relative to the mass of the ship.

@exploreplanets @astromonocyte There can be no sensation where there is no life. You'd be dead in milliseconds, feeling nothing.

When you see this photo from the surface of Venus, which sensation do you imagine first? The crushing pressure, the hellish heat, the searing smell?

@SimeonKoning @nyrath Apart from Casimir, which is a myth, those are all anti-particle effects, i.e. opposite charge, not opposite mass.

@ToughSf @nyrath Great painting! Zero to wicked in crazy seconds.

Wonderful painting of the XB-70 Valkyrie. The six General Electric YJ93-GE-3 turbojets produced 120kN in afterburning mode, for a total of 720kN. That still would have given the plane a thrust-to-weight of just 0.3 #art by Julien Lepelletier. artstation.com/artwork/4mLY1

@OkieSpaceQueen Seems to me that the test siren is also a test of the dog, which he's passing with flying colours. I hope someone gave him a toy.

Who on earth is funding these bullshit emdrive projects on Kickstarter?

@SimeonKoning @nyrath Since "negative energy" is entirely fictional, and no theory predicts it should exist, I can't see it's very important. Any unobtainium is a show-stopper; lots of unobtainium is no more so.

@qikipedia Throughout the 1812 war, you get the impression that neither side really had their heart in it.

In 1816, the United States built a fort to protect itself from invasion by Canada. There was only one small problem: due to a surveying error, it was built in Canada. It was later known as "Fort Blunder".

@NASAHubble And yet the next big space telescope, if it ever flies, is deliberately being placed where no servicing mission can reach it. #JWST

💡Fun fact! Astronauts traveled to the Hubble Space Telescope for five servicing missions. Their work is the reason why Hubble has lasted 30 years in space, showing us images of the universe as a more colorful and stranger place than we ever imagined.

Just as cars need maintenance, sometimes spacecraft need fixing, too. 🛠️When astronauts work on spacecraft in orbit, it's called space servicing. Have questions about servicing? Leave a reply in the comments for a Q&A from 12-2 p.m. EDT on 5/14 with astronauts and experts!

@virgingalactic @eventexco @UnderArmour In zero gravity, there is no "vertical."

Thrilled to win Gold in the Global @eventexco Awards for our unveiling of the world’s first spacewear system for private astronauts which we designed in collaboration with @UnderArmour. How do you showcase a spacewear system? On a zero-gravity, vertical catwalk, of course!

@shl That's like the gig economy, only there's no job.

We’ve made an incredible innovation in hiring: Pay someone to do the work they would be doing if they get the job. If they are able to do it, they get the job.

A tale of two theory papers "[the emission is] consistent with ... the synchrotron maser shock model. Rather than arising from the inner magnetosphere." (arXiv:2005.05283) "Emission is generated in the inner parts of the magnetosphere." (arXiv:2005.05093)
