Why Did 38 Satellites Fall Out of the Sky?
In 2022, SpaceX thought they'd have a routine launch of their latest batch of Starlink satellites. But of the 49 they sent to orbit, 38 ended up falling out of the sky! What went wrong? Predicting space weather and exactly how it affects the Earth turns out to be a bit complicated.
Correction:
0:20 This is actually not a photo of Starlink! This photo is most likely a long exposure of an airplane crossing the night sky.

At 0:17, your "Long exposure of a Starlink Satellite crossing the night sky" is obviously a long exposure of a plane... The flashing red light with accompanying flashing light just to it's left (obscured by the left steady on light) is a dead giveaway. Plus the distance changing between the two lines indicates that it's either coming closer or moving away from the photographer.
@simpleanswer8954

You must have magic eyes to see blinking lights in a still photo. Also, you seem to have some logic failure. So you believe that a satellite would not be moving across the sky relative to the photographer? How exactly to you think an orbit works? Maybe you're right and that is a plane. But the evidence you give isn't sensible. The lights aren't blinking, and a satellite can still move toward or away from your perspective. It just depends where you stand relative to the direction of its orbit.

You're so worried about that red light, I have to ask: then where's the green light? And since my original point was more about the quality of evidence: you have ignored and failed to address the whole concept of "Moving away from or toward". An orbit can and will make a satellite move away or toward your perspective. So the reasoning is absolutely not perfect. What, do you both think that satellites move straight up instead of around the Earth? If it's moving around the Earth, than it will ALWAYS be moving toward and away from something else on the ground. Both of you have failed to grasp the basic logic here. Maybe you're just ignoring that because you want to agree, but you're just flat wrong about the quality of the reasoning.

It's worse than that. Elon's satellites may destroy all other satellites in orbit.

That's why a higher public skepticism may actually help Like the aviation industry, many safety knowledge can be withheld to one company to make their competitors less safe and riskier for the customers But because people don't treat safety on a per-company basis but industry-wide So airlines with good understanding will not compete in safety There are some concerns about the new tech-style start-ups about EVTOLs that do not understand this safety culture in aviation And we are observing that many critical safety discoveries are kept trade secrets to other competitors We need more public skepticism towards the whole industry to educate these companies that withholding critical information about safety will ultimately be worse for them

If the sun's activity makes the Earth's atmosphere expand then it is also increasing the surface area of the atmosphere for any given pressure level layer and that means a greater ability to radiate heat into space. This would suggest that space weather can significantly impact on Earth weather in a 12 year cycle too.
@emmettturner9452
Жыл бұрын
Surface area only counts when there is a physical medium of exchange. Increased surface area of an aluminum heatsink with air lets you exchange more heat with the air. Increased surface area of the air with… empty space… doesn’t do much. You have to find a way to increase the heat that radiates as infrared light as opposed to simply exciting neighboring molecules.

@@mariebarker4499 Union Pacific 844, also known as the "Living Legend", is a class "FEF-3" 4-8-4 "Northern" type steam locomotive owned and operated by the Union Pacific Railroad for its heritage fleet. Built in December 1944 by the American Locomotive Company (ALCO) of Schenectady, New York, No. 844 is one of four surviving FEF Series locomotives and the only one in operation. The locomotive operated in revenue service until 1959. It was stored while awaiting scrapping, along with the rest of the UP steam locomotive fleet. In 1960, railroad leaders recognized the benefits of having a steam program and retained No. 844 for special activities, the kernel of what has become the Union Pacific's heritage fleet. Today, it is one of UP's oldest serving locomotives and the only steam locomotive owned by a North American Class I railroad that has never been retired. In 1944, Union Pacific and the American Locomotive Company (ALCO) collaborated on the FEF-3, a class of 10 locomotives designed to pull passenger trains at 90 mph. The FEF-3 could reach and regularly run at 120 mph; one locomotive reportedly pulled a 1,000-ton passenger train at 100 mph. All FEF classes were considered by the Union Pacific to be capable of producing between 4,000 and 5,000 drawbar horsepower. The FEF-3 class represented the apex of dual-service steam locomotive development; funds and research were being concentrated into the development of diesel-electric locomotives. Originally designed to burn coal, they were converted to run on fuel oil in 1946. Like the earlier FEF-1 and FEF-2 classes, the FEF-3 locomotives were ultimately reassigned to freight service. UP 844 was the last steam locomotive delivered to the Union Pacific Railroad, constructed as a member of the FEF-3 class of 4-8-4 "Northern" type locomotives. Upon its entry into service, the locomotive spent most of its career pulling a variety of passenger trains, such as the Overland Limited, Los Angeles Limited, Portland Rose and Challenger. From 1957 to 1959, UP 844 was reassigned to fast freight service in Nebraska when diesel-electric locomotives took over passenger service. After commercial steam operations ended in 1959, the 844 and the rest of the FEF-3 class was placed into storage. Saved from scrapping in 1960, No. 844 was chosen for rebuilding and is now used on company and public excursion trains, along with hauling revenue freight trains during ferry moves. Since 1960, No. 844 has run hundreds of thousands of miles as Union Pacific's publicity locomotive. The locomotive often pulled the annual Denver Post-sponsored Cheyenne Frontier Days train that ran round-trip from Cheyenne to Denver every July before it was discontinued in early 2019.
