Starliner, the Boeing spacecraft whose launch was delayed by a helium leak, has now developed four additional helium leaks after docking successfully with the ISS.
They had to delay the docking due to a little problem with thrusters…
Five of the 28 thrusters were not operating but, after troubleshooting, Boeing recovered four of Starliner’s malfunctioning jets and NASA allowed the spacecraft to dock.
A contractor for Nasa urged the space agency to conduct more safety checks before the highly-anticipated first launch of its Starliner rocket – which is set to take off as soon as next week – “before something catastrophic happens”.
It was supposed to launch last week, but someone spotted a valve problem — *minutes* before the countdown procedure was about to start.
They’d better check for door plugs while they’re at it.
Boeing does not give a rat’s ass about whoever uses their products. They‘re only interest in paying dividends to stockholders. And of course paying the CEO’s ridiculously high salary.
NASA is trusting the future of space travel to people like Musk and companies like Boeing. Using taxpayer money to reward greed and incompetence.
Over time, that water has nearly all been lost. Figuring out how, when and why Venus lost its water helps planetary scientists like me understand what makes a planet habitable — or what can make a habitable planet transform into an uninhabitable world.
The process in which Venus lost most of its water is called “hydrodynamic escape.” When Venus got too hot, the hydrogen in its atmosphere left. (The linked article explains this using a metaphor of having too many blankets on your bed.)
However, Venus is still losing hydrogen, even though there is too little of it for hydrodynamic escape to work. So, logically, there must be another process at work: “HCO⁺ dissociative recombination,” in which individually positively charged atoms of hydrogen, carbon, and oxygen in the atmosphere react with negatively charged electrons. The process was first examined on Mars, and based on a reexamination of results from previous missions (Pioneer Venus 1 and Pioneer Venus 2), the same research group thinks it’s time to try it on Venus…perhaps a first step to seeing whether Venus had life at some point.
Japanese space company Astroscale Holdings Inc has unveiled what it calls the world’s first publicly released close-up image taken of space debris, hailing it as progress toward understanding the challenges posed by trash orbiting Earth.
NASA says it is once again able to get meaningful information back from the Voyager 1 probe, after months of troubleshooting a glitch that had this venerable spacecraft sending home messages that made no sense.
There are many words that could be used to describe WASP-76b — hellish, scorching, turbulent, chaotic, and even violent. This is a planet outside the solar system that sits so close to its star it gets hot enough to vaporize lead. So, as you can imagine, until now, “glorious” wasn’t one of those words.
This planet (located in the constellation Pisces) seems to have a rainbow effect of concentric rings…despite being so hot that iron falls from the sky.
Researchers will fly rockets into the path of the eclipse, stand in zoos watching animals, send radio signals across the globe, and peer into space with massive cameras.
And you don’t need to be a scientist to take part.
If you’re lucky enough to have no clouds or rain, that is.
Things the eclipse affects:
Radio waves
Animal behavior
The birds and the bees (seriously; read about what tortoises did last time)
Things scientists can view thanks to an eclipse:
The solar wind (plasma on the surface of the Sun)
Coronal mass ejections (which interfere with satellites)
Dust rings around the Sun and possibly even new asteroids
The East Coast of North America, where most of my relatives live, is currently 13 hours behind me in Japan. So the event will be long over by the time I wake up.
Hope to see video of it on the morning news show tomorrow!
The asteroids in question are Iris (124 miles / 200 km in diameter) and Massalia (84 miles / 135 km). Both are in the asteroid belt between Mars and Jupiter. Iris is about the size of the US state of Maryland, while Massalia is roughly the size of Connecticut.
Note that the same observatory also found water on the Moon, about a “12-ounce bottle” worth. Not nearly enough for a settlement, but where there’s surface water (albeit trapped in soil on the surface), there’s likely to be more underneath.
“It should be able to make a smarter AGI, then an even smarter AGI, then an intelligence explosion,” he added, presumably referring to the singularity.
