Let The Good TImes Roll

Elon Musk shrugged off naysayers on Friday morning, excitedly tweeting 'let the good times roll' after officially taking over at Twitter and firing three senior executives.

Within hours of taking the keys, Musk fired CEO Parag Agrawal, CFO Ned Segal and top counsel Vijaya Gadde - the woman responsible for banning President Trump after the January 6 riots.

Photos show Musk chatting casually with Gadde and other employees at the HQ's coffee bar, hours before the gauntlet came down.

Gadde, widely considered the 'head of censorship' at Twitter, had been vocal in her criticism of Musk; she cried during a meeting in April after he first announced plans to buy the company.

Musk had publicly slammed her for squashing links to stories about Hunter Biden's incriminating laptop before the 2020 election.

She walked away with a sizeable payout - a total of $72million in stocks that she owned, salary and benefits and stocks that had not yet vested when she was in her position but which are now paid out as part of the deal.  READ MORE...

Space Plane with 3D Printed Engine

A hypersonic 'spaceplane' dubbed Delta Velos (pictured) has been developed in inner Sydney by a team of dedicated engineers

A hypersonic 'spaceplane' is being developed in inner Sydney, but the passengers will be gadgets not people. Named Delta Velos, the sleek vehicle will be powered by four green-hydrogen fuelled scramjet engines to send small satellites into orbit.

Engineer Simon Ringer and his team at the University of Sydney are working with Australian aerospace engineering startup Hypersonix Launch Systems on the zero-emissions spaceplane.

'There will be this Australian-made vehicle which is just a complete leap in technology, travelling at hypersonic speeds,' Professor Ringer told AAP on Thursday.

With the development of sophisticated 3D printers, the so-called additive manufacturing tools, objects have jumped from fun and wacky to industrial and useful.

Additive manufacturing will be used to make flight-critical parts of the spaceplane, which will be powered by the world's first 3D printed scramjet engine.  READ MORE...
