The thread for space cadets!

You can create artificial gravity with centrifugal force by spinning an object you are inside. One of the Gemini missions tethered a capsule to another spacecraft and spun it up to test it. The ISS was also originally going to have a large spinning section which was downgraded to a small spinning machine for experimentation but eventually that was dropped.
 
If you are inside a spaceship which moves with constant acceleration ~10 m/c2, you will also experience 'normal' gravitation. With current technology it's impossible to maintain for a long time, but if we are talking about sci-fi movie and interstellar travel, this can be plausible explanation.
 
reading stuff ı discover this Spitzer Space telescobe was supposed to track the Oumua or whatever you spell the stick (11/2017 U1) but failed to see it at a time when it was supposed to pass relatively close by . Is this an already declared thing in addition to its speeding up and down , or "new" as a demonstration that it either has cloaking or has jumped already ?
 
Spitzer has been out of helium for a decade which means it can't see most of what it was designed to see. It's batteries are also failing and based on other telescopes of the same era, I'm going to bet it has serious reaction wheel issues but I haven't been able to confirm that. In other words, if it couldn't see anything, that's not entirely unexpected. It's due to be retired early next year.
 
The YouTuber Everyday Astronaut did a great interview with Jim Bridenstien (the Administrator of NASA) at SpaceX headquarters.

It was a really good interview and the way Jim explained the use-cases and utilities of the Lunar Gateway made a lot of sense and made me less skeptical of the approach. One thing that went unsaid that I think is an important angle of the program is that as a national prestige project, it will be hard to cancel due to shifting political winds once it gets underway. Apollo had an end-goal that it achieved (plus Vietnam and a much smaller US economy) that made it easy to cancel but the ISS has gone on for decades even as everyone has questioned its utility. The shuttle only got sunset when it killed a second group of astronauts but was quickly replaced by new programs. I think if they can get Gateway up and running - and especially if they can land the first female astronaut on the moon - it will be able to continue on and be built upon out of inertia if nothing else.
 
never take no for an answer , if you are going to be something or whatever , so Spitzer is covering up !
 
The first all-female spacewalk in history is scheduled for this week. NASA also unveiled prototypes for new lunar space suits, so that's pretty cool.

SpaceX has filed for permission to launch and additional 30,000 internet satellites.

Proving once again that you can't have a news story about women without mentioning clothing. :)

Ironically, NASA tried to have an all-female spacewalk months back and went on a publicity blitz about it, only to have to cancel it at the last minute because they did not have enough spacesuits of the right size to fit both spacewalkers.
 
NASA has managed to get the heatflow probe on the InSight lander moving again by pressing down on it with the lander's arm. This has enabled it to dig 2 cm deeper and also show that it is a lack of friction and not a rock which was causing it to get stuck. But it's still yet to be seen if the probe will get stuck again once it's fully underground.

Democrats in the House are balking at the potential cost of accelerating the Artemis moon landings by 4 years and Republicans are balking that NASA is considering using commercial rockets for parts of the missions instead of solely using the government's own SLS which is being designed and partially built in Alabama. Free market ftw /s

Latest NASA PR photo - astronauts with ray guns!
(However, it begs the question: what's out there that needs zapping?)

I'm not sure if this qualifies as space-related, but it combines satellite imagery and one of my research interests. :)

The short video shows a usually invisible phenomenon known as atmospheric gravity (not gravitational!) waves.
These sets were created by lightning storms over land in Western Australia and travel for many hundreds of kilometres (or "football fields" if you are viewing from the USA).

Blue Origin is teaming up with Northrup, Draper Labs and Lockheed to work on a manned lunar lander for the Artemis program. This is a smart move from all companies as it's clear that there will be a small number of contract winners for this effort and this means they are more likely to get a chunk of that pie. It's also unclear that the effort will even be funded, so this allows them to share costs on development that may go nowhere. Though to be honest, I doubt any of these partners outside of Blue will spend much on the effort without government contracts.

Nanoracks is planning an experiment to cut up a dummy upper stage on orbit to demonstrate their ability to repurpose upper stages to turn them into usable platforms. They are partnering with a Canadian agency for the test. Cool stuff.

oh my , USN is offended ! So , after this smally little batch of trolling they give up and turn the leadership of Alien "investigations" to US Army ! Which perforce goes and signs a deal with the company in question ! They have pieces of metal that are relics of the Roswell crash ! Turns out they date back to 1990s . Which then naturally leads me to think of the Cold Fusion scam of the said 1990s . Same people , same materials , same methods , same conditions and they can't repeat the outcome of the experiments , which happens to be the bedrock of science or something afterall or something . Some major company owner is named , like even claming ownership of the pieces . Leads me to remember the "science magazines" , actually advertising glossies for stuff ı would never be able to afford and one of them had it , Cold Fusion 2.0 ... The re-awakening of interest in me to buy "science magazines" should match the time my niece won a place in the engineering school in university , so it must be early 2010s and one had this totally cryptic article . A breakthrough in energy producing , you know , nuclear power station on a truck ... They claim they have net production , and on a colossal scale ! And you can just smell they have no actual idea on the theory , despite having some whole factories ready to roll out merchandize immediately , nor they can ever guarantee that it will work on any given day . You know , when you need power ... Like when to fire lazers onto incoming missiles that have towels on their warheads ? So , this is how Lockmart decided they could convert a battery of tons of material they didn't have into a fusion plant ?


the change of guard is also cool . USN makes it parting shot with how they ruled the wawes and it was only down to inexperienced youths failing on their first missions that the Red Banner Fleet could photograph US carriers just twice or something , through submarine periscobes , otherwise cool and informative kind of articles ... US Army enters with the pictures of what they will do , when they actually learn what they are supposed to be talking about . Like watching dynasours or parlour tricks like putting your arm into a tear in time and space and it appears somewhere else . Obviously not true , even if the source website had them in the first outing like months ago , because they are obviously related to this American thing , the girl next door , to peep/check on what she's doing and grabbing when she's not looking . But then the portable wormholes will be the biggest invention since the portable toilet - and as a military tactic as well : Crp on your enemy / rain excrement on 'em !

but then this is like old stuff . It's called the Atomic Battlefield Infantry , dear people , especially the webmaster of the source site , called area of fighting or whatever . ı DO really hate it when opening like 5 pages (simultaneously to save them) like drives the webcafe computer to saturation and when saved half of the pictures do not appear anyhow . Yeah , there are people who can't just read stuff one by one . Like ı have neither the time nor money . Anyhow , this is like 50s stuff when Russians teleport heavily armoured troops with edged weapons , like a bayonet charge , because Dark Magic , because Rasputin was a shaman , because you are worthless and worth nothing if you challenge Americans who know everything , including Dark Magic . So , US Army goes 7.62x51 which kicks as much as the old Springfield round (so not much use in automatic fire) , but balistically poor when compared to the old Springfield round ... which means nothing . As it has to penetrate the chargin' mujik in lead plate in 10 yards distance . You would think Russians would ride bears into battle ? ı would think Rasputin would fly all about the field , breaking hypersonic wind , shooting lightning bolts from his eyes and slapping people silly with his flapping beard ? US Army thought this to refuse the British .280 round .

oh also , while ranting about how ı fail to get stuff from the web , one must remember this cool magazine . One ı had proven that ı was reading through stuff with a post possibly in late June 2018 , with "proving" P-38 as a divebomber . You know , some Brit author attacks Lockmart in WW II with the foolishness they showed in the original Lightning and this will "help" with the Qatari Fighter jet they are doing in Ankara . And they deny , with a deal with a pirate site and Google and stuff , because it takes months for me to be translated/understood . As if Somebody would not have a subscription already and would not make it available as soon as ı leveled the US with orbital bombardment and have a piece on why they have it wrong with the Harrier , even if ı still don't know what . (Oh , of course they have every right as owners and authors)

and naturally it's just down to the mighty great US now able to analyse UFO "pieces of metals" ... Which they were most unable to understand as magnesium in 1947 or '87 or 2017 . A wide range of reading might instead help a clearer vision . Like one of those Tuskagee men from the Red Tails (who was the last of them to pass away) was a Colonel or whatever that ran the Project Blue Book for a while , 'cause every human being must unite when facing a real true danger , irregardless of what might the Devil say about the glory of the Whiteman . An ace in the sleeve , ready to be used in "emergengencies" , hinting they have all the "Bell" and all those Nazi Flying Saucers , ready to implement Heil Nixon! to Heil Obama! come some rainy day . While Reagan was truly a genuwine , calling on the world to see truth and join good old America when he had his concept images of SDI ... While it was equally logical for Mugabe to lead the world , because ı don't know , Zimbabwe is the last in any alphabetical list of countries and why not ... Then , now ? Simply changed into "All Hail Mighty Glorious Trump, First, Last, Unique, Threatens Sanctions, Dooms China And All Comers!" because he faces impeachment ...


and finally the former pinnacle of yellow journalism assures us Trump is Darth Vader , because he forced Microsoft to win over Amazon in some US Military project called JEDI , something of a cloud in the net . Dear BSS , now that we didn't make you US President , we won't impeach you either , and aren't you mighty or anything ?

done ? Just about ... The true response of America to teleporting mujik was the Earth Warriors or Monks or whatever , reaching to its zenith in Reaganite times . Those who stared at goats . Well , being the idiot ı am , ı have truly failed to see the essense here . Were goats used in looks-can-kill experiments because they were aplenty and were already in general use , wounding them so that the Special Forces crew could study first aid and medical care with limited means ? Or every enemy of the US is a "goat-lover" and destroying goat stocks of targeted countries would start rebellions or something ?
 
The heat flow probe of the Mars Insight lander made some good progress in digging itself into the regolith and then unexpectedly nearly ejected itself from the hole. The probe is the white stick to the left in this image and it should be inside the ground, not above it.

insightmole-2019oct27.jpg


I don't know if they'll be able to save it. It seems that this probe is not fit for function in the Martian environment. There could be a few different problems, either the soil has material properties that were unexpected or perhaps the lower gravity means that the hammering mechanism is not as effective as anticipated.
