I am talking o a reporter about this in a couple hours: https://regina.ctvnews.ca/from-outer-space-sask-farmers-baffled-after-discovering-strange-wreckage-in-field-1.6880353

This is about an hour away from my farm, so this'll be a fun conversation, and yet another great opportunity to tell a lot of people about what a huge problem we have with unregulated commercialization of orbit. (Also I just redid my slides for my public talk next week, this is going in!)

@michael_w_busch @WTL @sundogplanets There was that chunk of metal that crashed through the roof of a house in Florida. It was not hot enough to start a fire, but did damage the house.

NASA appears to be desperate to find a way to get Americans to accept sonic booms. Their mission now? How loud can they be all day long before people get really pissed off?

EricFielding,
@EricFielding@mastodon.social avatar

@lauren Yes, the NASA Space Shuttle caused sonic booms over LA on its way to landing at Edwards Air Force Base in Palmdale. I believe that 1985 was the year they flew the most times, 9 times that year, with 7 landing at Edwards.

BATTLE FOR THE HORN:
Just here to provide some updates on the geopolitical skirmishing that has involved a number of major players in a race for control and influence of Somalia's coastal frontiers off the Gulf of Aden...which borders the Red Sea and the lucrative Bab El Mandeb strait. That strait has a huge impact on global oil shipments, and has been explored as a possible Israel weapons delivery portal.

@ZekuZelalem Thanks for your explanation about this topic. The news media in the USA has been ignoring this.

Some 'science' photo libraries are...questionable.

This photo claims to be "Ant carrying aphid egg, SEM" colorized to highlight the "egg" but look closely! (https://www.sciencephoto.com/media/370844/view/ant-carrying-aphid-egg-sem)

It's NOT an egg. That's just part of the ant's mouth! Take a look at the second set of photos by Hugo Darras. ( https://flickr.com/photos/fourmis/5004761756 ) you can see this is part of her maxillae, the part she uses to collect liquid.

How did they decide it was an aphid egg? Most aphids don't even lay eggs they give live birth!

Three photos of an ant's head as seen from below. The photos show how the maxillae can extend, it also shows that the "egg" in the other photo was just part of the ant's mouth.

@futurebird I also see a lot of videos on YouTube with crazy interpretations of geology and geophysics. Not quite the same as this site that claims to be science photos, but scientific misinformation is spreading rapidly these days. I don’t know how we can reduce the impact.

Hello Toronto - I'm giving a public talk there in 8 days. Want to hear me yell about satellites for an hour? Come say hi!

@ai6yr @chris_bloke There are many more Irish-Americans than people in Ireland.

EricFielding,
@EricFielding@mastodon.social avatar

@ai6yr @EricFielding @chris_bloke Yes, about 30 million people in the USA have Irish ancestry and there are only 7 million people in Ireland now. https://en.wikipedia.org/wiki/Irish_Americans?wprov=sfti1#

EricFielding,
@EricFielding@mastodon.social avatar

@chris_bloke @EricFielding @ai6yr True, many immigrants from Ireland came to the USA in 1849-1850 during the Potato Famine, which was a long time ago, but some have kept a strong identity as Irish-Americans, especially in Boston and New York.

@ai6yr @tsherrygeo @douglasvb @jds @bosquebill The San Andreas Fault in SoCal has had earthquakes every 150-300 years for probably at least 5 million years, so the deformation near the fault is accumulation of many earthquakes.

@mattblaze Interesting to see how the lens and camera you used was able to remove the usual perspective distortion. It makes the photo more surreal to my mind, in addition to the geometry of the buildings. The O'Keeffe paintings have more regular perspective.

What is proper to say for , an anthropomorphism but nonetheless an expression of love, is that it stayed in the battlefield erect and functioning until the very end.

The is still alive, and we'll probably be hearing about it for as long as it has power to transmit its beacon and continues to devote a few minutes of 's time every sol to listening for it, which may be well into Martian autumn.

What a journey this has been!

EricFielding,
@EricFielding@mastodon.social avatar

@65dBnoise Yes, it is sad that helicopter is not going to fly again. It has done so much more than the original mission was designed to do. They have learned so much about how to operate helicopters on Mars that they are including more powerful helicopters in the Mars Sample Return mission planning. signing off.

Happy mother’s day to my Camponotus pennsylvanicus queen! She is nearly four years old this summer and the proud mother of nearly 700 beautiful daughters. Here she is today and years ago where her colony had only 30 ants. She has done an amazing job raising a huge colony!

The same queen protects a small pile of brood.

@futurebird Can one queen have 20,000 baby ants? That seems difficult.

Morocco interferogram from NASA Caltech-JPL ARIA processing. Edit: after original posting, we realized that the sign of the displacement colors was reversed. The online version at this URL is the correct version. The ground near and east of the epicenter (red symbol) moved up and southeast, towards the satellite, as expected for thrust earthquake. https://d1z62tir4fw0q0.cloudfront.net/202309_Morocco_EQ/Displacements/Sentinel1/D154_20230911_20230830/MOROCCO_S1_20230830_20230911_UNW.png

    What is the best way for an organization to create a shared account here on Mastodon or another Fediverse instance? An organization that I work with wants to migrate from the former bird site and create an account but they are concerned about the security risk of a shared password. @mastodonmigration

    : A $19 Million investment has been made into installing solar panels over irrigation canals in the USA, to generate renewable energy and increase water conservation. What are your thoughts on this plan? News Source: https://cleantechnica.com/2024/04/05/19-million-for-innovative-solar-panel-installation-over-canals-from-investing-in-america-agenda/

    EricFielding,
    @EricFielding@mastodon.social avatar

    @mattferrell Sounds like a win-win effort to me. The canals already cut across the landscape and have road access. It is not tearing up natural areas with wildlife. I only wonder who is going to be paid to do the installation and who will get the benefit of the electricity that is produced.

    The Icelandic TV network RUV has a great live webcam that is on top of a hill north of Grindavik and showing the lava flowing into the town. It is sad to see lava reaching people's homes but all the people were evacuated in time. https://www.youtube.com/watch?v=Bqudj0x0POA

    EricFielding,

    Today, 15 January, the eruption has ended. The fissure close to the town stopped flowing after destroying three houses. The larger fissure further north has only a small residual vent activity, but flows yesterday covered the main road and destroyed the hot water pipes bringing heating to Grindavik. The berm or earth wall deflected most of the lava from the northern fissure and was a great effort.

    @EricFielding@mastodon.social avatar

    Iceland news service has a live updates page in English. They report that the earthquake rate is slow again today (Monday) and the authorities are considering allowing more people to visit their homes in Grindavik and retrieve items. The hot water supply has been damaged by the cracks and deformation in the rocks under the town. https://www.ruv.is/english/2023-11-10-magma-intrusion-under-grindavik-eruption-likely-live-396249

    Where are flood waters flowing after major storms? How much did the land move during an earthquake or volcanic eruption?

    A NASA-sponsored project called OPERA is tracking a changing Earth by merging data from multiple satellite missions.

    The European Space Agency (ESA) ERS-2 satellite re-entered the Earth's atmosphere earlier today over the North Pacific Ocean. I used a lot of radar images from this satellite in years past, but I am happy that they were able to de-orbit it and reduce potential space junk. It was some luck that it fell over the 75% of the Earth that is ocean.

    NISAR, the soon-to-launch radar satellite from NASA and the Indian Space Research Organisation (ISRO), will measure key Earth vital signs, from the health of wetlands to ground deformation by volcanoes to the dynamics of land and sea ice.

    Short for NASA-ISRO Synthetic Aperture Radar, NISAR will provide the most comprehensive picture to date of motion and deformation of frozen surfaces in Earth’s ice- and snow-covered environments, collectively known as the cryosphere.
