With all the (rightful!) vitriol surrounding the Space Flight today, please don't let the conversation ignore Amanda Nguyen (because the media certainly has..).

Ms Nguyen went to Harvard and interned at Nasa twice. She conducted research on exoplanets for the Harvard-Smithsonian Centre for Astrophysics.

While she was a student at Harvard and interning with Nasa in 2013, she was raped. This paused her dream of becoming an astronaut and experiencing space travel. As a result of her strength and compassion in response to that attack, Ms Nguyen decided to leave Nasa and engage in activism work that challenged the narrative around victim-survivors, and ultimately she created Rise - a non-profit organisation which aims to protect the civil rights of sexual assault victims and rape survivors.

In 2016, the Sexual Assault Survivors' Rights Act passed through the Senate and the House of Reps, and was signed into law by Obama. The law protects, among other rights, the right to have the evidence of a rape kit preserved without charge for the duration of the statute of limitations, and the right to be notified before the destruction of evidence held in your case so you can apply for it to be kept and archived.

Amanda Nguyen is a brilliant and amazing person who was able to experience a tiny edge of a dream she had given up on. Please be gentle with her story when (rightfully) protesting some of the other women involved.

Studierende der #TUGraz aufgepasst: im Jänner gibt's an 3 Donnerstagen Nachmittag eine IMHO wirklich spannende LV, die von Kolleg:innen meiner Firma gehalten wird.

Die erzählen aus unserer Praxis mit großen Industrie-Software-Projekten und zeigen auf, wo was heikel war, worauf man aufpassen muss und so weiter.

Fand ich damals als Student selber höchst spannend, da man sowas selten bis nie wo hört.

Efficiency gains from engines will still be vital for the industry.

The most marked change in the appearance of #engines could be the return of the open #propeller.

The design dispenses with the #nacelle
– the cover
– to allow for a bigger fan that offers more propulsive force.

Superficially, it will look like existing turboprop engines,
but with the ability to fly at Mach 0.8, or 80% of the speed of sound
– the same as current jet engines.

#CFM, a joint-venture between America’s General Electric and France’s Safran, has said that its open fan #Rise engine could theoretically reduce fuel consumption and carbon emissions by 20%.

The company says it can reduce noise, which put paid to a previous prototype in 1986.

It will still have to persuade regulators and passengers that the engines will be safe if a blade breaks in midair.

As well as radical changes to airframes or engines, manufacturers are constantly looking for ways to salami-slice #fuel burn via small gains.

#Winglets, the curved tips of wings, were first introduced in the 1970s in response to the then oil crisis,
mimicking birds’ wings to reduce drag.

The split winglets on the 737 family since 2014 can reduce fuel burn by as much as 2% during a long journey, according to the Seattle-based manufacturer Aviation Partners.

(For plane-spotters, they double as the easiest way to distinguish a 737 from an A320.)

Birds have had millennia to evolve the ideal features for efficient flight,
so aviation designers have constantly used them for inspiration.

Airbus is experimenting with #gust #sensors on the front of the aircraft to register during turbulence,
with automatic responses from control surfaces of the wing,
similar to a bird’s constant adjustments to movements in the air.

#Concorde, which flew on only a limited number of routes, was the last passenger plane in service with a truly distinctive design.

The supersonic jet, which had swept-back, delta wings, was retired in 2003.

#Boom #Supersonic, a startup, is testing the technologies for a proposed “son of Concorde” with a similar look.

That plane would only ever be a niche service, flying 80 passengers at a time on premium routes.

But there is a possibility that Boeing and Airbus take radically different approaches to the workhorses that carry billions of passengers each year.

If the manufacturers go in different directions, then passengers might start paying serious attention to plane design, says Addison Schonland, an analyst who tracks the industry at AirInsight.

“I don’t think we’ve ever had a situation before, to look at an aeroplane and say, ‘that’s completely different’,” he says.

“How will people react to seeing those novel shapes?”
