@SpaceX backed Starlink @SpaceXStarlink #Broadband #Service could debut in #India in 2022:
#SpaceX, venture by #BILLIONAIRE #ElonMusk @elonmusk aims to launch company's own #Satellite #internet service. #Aerospace company listed multiple Indian locations on website.
#Thread #tech
Services will be available on first-come-first-serve criteria. Starlink as concept is collection of tiny internet satellites orbiting closer to #Earth surface, at altitude of 550km, which, when compared to larger navigation and #communications satellites operate from medium Earth
Orbit of around 2,000 to 35,000 km or, at times geosynchronous orbit, usually operates from beyond 35,000 km. Potential users can pre-book Starlink services in India on website for refundable amount of $99 or Rs 7,265.
Due to proximity to planet's surface, Starlink and other...

(1/7) On this #WorldTurtleDay discover the story of Thunderbird, the loggerhead turtle 🐢 that travelled 6000km. Her epic journey illustrates 2 of the major threats that many #marine #species face 🦈🐋 – entanglement in #ghost fishing gear and #bycatch in industrial #fisheries 🆘
(2/7) Thunderbird was found entangled in ghost fishing gear by #SaveTheMedFoundation in July 2020, and taken to the @PalmaAquarium rescue centre in Mallorca 🐢

🇪🇺#EUSST contributes to protecting the safety & security of European economies, societies & citizens.

Our Operations Centres are monitoring a potential collision of two large, inactive #space objects. EU #SST estimates a probability above 1% that they may collide in two days👇
The two defunct objects are OPS 6182 (1978-042A), a meteorological #satellite🌧️🛰️ and rocket body🚀 SL-8 R/B (1981-041B). The network of EU #SST sensors📡 has been requested to observe the objects and provide additional measurements.
Stay tuned here for more updates.
#spacedebris
⚠️Update: according to #EUSST's latest estimates using data from its surveillance radars, the close approach between #space objects SL-8 R/B & OPS 6182 expected by tomorrow will have a miss distance under 10m and a Scaled Probability of Collision over 20%! +updates to follow soon

Quand #Panama bloque #Suez : le porte-conteneurs #EVERGIVEN bloqué au sud du Canal de Suez, vu par le satellite #Sentinel2 le 24 mars. Première leçon : faire demi-tour dans un canal de 300m de large n'est pas l'idée du siècle quand on mesure 400m... #Copernicus #EarthObservation Image
Mise en service en 2018, #EVERGIVEN est un gros navire, un des plus gros porte-conteneurs : 400 mètres de longueur et 220000 GT (drôle d'unité) de tonnage. Il appartient à la société taïwanaise Evergreen Marine et bat pavillon panaméen. Photo Kees Torn #Suez Image
L'accident du porte-conteneurs #EVERGIVEN s'est produit le 23 mars au matin, bloquant la totalité du trafic du canal de #Suez. Les données #AIS montrent que ça se bouscule au portillon. Pour fixer les idées, une vue globale du canal de Suez. Image #Sentinel2 du 24/03 #Copernicus ImageImageImage

May had been asking me whether Isha encroached forest lands. IMO this is deviating from actual issue. Read full thread

Isha didNOT build on forest dept lands as such but it VIOLATED rules in other ways

Old Satellite image & map show that it was not forest but revenue land
Inorder to protect out environment, we had framed laws to secure permissions from necessary authorities. Since it was farmland and since it came under Hill Area Conservation Authority, necessary permissions were to be secured from respective offices
In their webpage, Isha says that they secured permission to construct statue on Sep - Nov 2016. But prior to securing permission itself they started constructing. Attached #Satellite images from Jan & Feb 2016 show that construction had already started before securing permission

.@NASA confirms that the dent in #Earth’s protective shield is splitting into two as it gets bigger - by @pabsgill

businessinsider.in/science/space/…
The bigger the anomaly gets the wider its sphere of influence. A weak magnetic field means that the particle radiation from the #Sun gets closer to the #Earth’s surface than otherwise.
In addition to messing with compasses and throwing bird navigation off, this means it can also knock out onboard computers and interfere with satellites on their rounds to collect data.

BREAKING: @US_SpaceCom accuses #Russia of conducting "non-destructive test of a space-based anti-satellite weapon"

"The Russian satellite system used to conduct this on-orbit weapons test is the same satellite system that we raised concerns abt earlier" per @SpaceForceCSO
Per @US_SpaceCom, the July 15 test was similar to one by #Russia in 2017

@SpaceForceCSO calls it "further evidence of Russia's continuing efforts ...consistent w/the #Kremlin's published military doctrine to employ weapons that hold US & allied space assets at risk"
Latest anti-#satellite weapons test " highlights #Russia's hypocritical advocacy of outer space arms control...while clearly having no intention of halting its own counterspace program" per @StateDept Asst Sec Christopher Ford

A thread with some of the story of the “battery card” - the first pirate card sold for hacking DirecTV in the mid 1990s.

#tvpiratehistory
The battery card was a PCB slightly longer than a credit card, with chips on it to emulate a smartcard. Visible on the top of the card when inserted in a satellite receiver was a coin cell-type 3V battery.
Because the chips are thicker than a smartcard, the board would extend out of the cardslot to make room for the chips. Inside the satellite receiver, the battery card emulated an original smartcard. The satellite receiver wouldn’t know the difference.
