Yeah it's still going to be a few days until we really get much more from perseverance as it's undergoing all its checks and is getting set up

Probably getting some audio on Monday they said. Apparently the microphone turned on as the rover hit the atmosphere and recorded all the way down

Unfortunately the microphone didn't work and didn't record the audio of the landing but everything else seems to have worked fine and they got all this video of the landing

Sometimes it is useful to contemplate "Ye Olde" Science - results that may have been forgotten or not sufficiently appreciated - not just shine on the new stuff.

This is a excellent article revisiting a fascinating study from the late 1960's.

Sydney student helps solve quantum computing problem with simple modification
Sydney university student Pablo Bonilla, 21, had his first academic paper published overnight and it might just change the shape of computing forever.

As a second-year physics student at the University of Sydney, Mr Bonilla was given some coding exercises as extra homework and what he returned with has helped to solve one of the most common problems in quantum computing.
...
"We just made the smallest of changes to a chip that everybody is building, and all of a sudden it started doing a lot better.

"It's quite amazing to me that nobody spotted it in the 20-or-so years that people have been working on that model."
...
Mr Bonilla came to Australia with his family as a boy.

"I was 11 years old when I came to Sydney," he said.

"We came from Uruguay in 2011, so it's my parents, one brother and one little sister and they're awesome.
...
Mr Bonilla showed academic promise as a student at Bossley Park High School.

After completing HSC-level maths at the age of just 15, he was invited to work on a research project at the University of Sydney.

Mr Bonilla is now a fourth-year honours student and plans to go on to do his PhD.

Steak-Um is right. Back in the day the Earth being at the center of the universe and diseases being caused by bad humours was “science”.

Science may be about finding truth but it’s not always true.

It is absolutely incredible that we went from not being able to fly a heavier than air aircraft to flying a helicopter on another planet in under 120 years.

Humans are amazing (and terrible, but today I choose to walk on the sunny side of the street).

A flat-Earth conspiracy theorist and YouTuber has taken a spirit level onto a plane to “prove” that Earth is flat once and for all. His "experiment" has since gone viral, just not in the way that he'd hoped.

YouTube conspiracy theorist D. Marble took a flight from North Carolina to Seattle in order to “monitor whether or not the pilot would dip the nose of the plane to compensate for curvature”.

‘Game changer’ treatment cuts heroin use
An opioid treatment being introduced around Australia has been dubbed a game changer after dozens of users at Melbourne’s safe injecting room stopped taking heroin.

The Richmond site was among the first in Australia to provide depot buprenorphine, a slow-release injection given weekly or monthly, outside clinical trials after it was approved for use in September 2019.

The treatment is designed to stop withdrawal symptoms, and in most cases blocks the effects of heroin altogether, helping to reduce and stop heroin use.

Medical director Dr Nico Clark has analysed the experiences of the first 41 people to try it at his clinic, finding that 59 per cent did not use heroin at the safe injecting room at all over eight months of monitoring from September 2019 to April 2020.

“For the majority of people, they either stop or have very, very little heroin use,” said Dr Clark, who believed it was the first injecting room in the world to administer the long-acting treatment.

Participants all used heroin at the injecting room 10 times in the 28 days leading up to treatment, on average. This dropped to an average of less than once in the first 28 days of treatment.

If you tried to start a car that's been sitting in a garage for decades, you might not expect the engine to respond. But a set of thrusters aboard the Voyager 1 spacecraft successfully fired up Wednesday after 37 years without use.

Voyager 1, NASA's farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or "puffs," lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980.
Woooo!!!

Guys like that are pretty comfortable with risk. Both of those projects have been very safety conscious although the Virgin project did lose 1 pilot but they fixed the error that caused the crash. Remember also that both of these projects are suborbital.

Calling where Branson went today "space" is quite a stretch. It only got up to about 86 kilometers which is right around the boundary of the mesosphere and thermosphere and below even where the aurora borealis are. Didn't even get 1/4 of the way up where the space station is. The Kármán line, which is the generally accepted start of space is around 100km. So all it was really was just a high altitude atmosphere flight, not even a suborbital space flight.

Yeah but that's just the same weightlessness you get from being on a roller coaster and not from being in orbital space.

Which was all this is. Alan Shepard did the same thing 60 some odd years ago with the computing power of a Gameboy and balls of steel.
