Space Debris Alert: Fragments from Inactive Russian Satellite RESURS P1 A significant #spacedebris event has been detected by LeoLabs, originating from the inactive Russian satellite RESURS P1 (SATNO 39186, Int Des 2013-030A). Between 2024-06-26 T13:05 UTC and 2024-06-27 T00:51 UTC, "a number of fragments were released." Additionally, the 18th Space Defense Squadron (18 SDS) has also confirmed the breakup of RESURS P1 (#39186, 2013-030A), likely occurring on June 26, 2024, between 1512-1640 UTC. As of June 26, 18 SDS is tracking over 100 associated pieces at an estimated 350 km altitude. These fragments are now part of routine conjunction assessments to ensure spaceflight safety. Analysis is ongoing. #SpaceSafety #OrbitalDebris #SpaceSustainability #LeoLabs #SatelliteMonitoring #SpaceNews #18SDS

In 1798, a monumental naval confrontation unfolded in the waters of Aboukir Bay near Egypt, shaping the geopolitical landscape for centuries to come. The Battle of Aboukir Bay, also known as the Battle of the Nile, saw the British fleet under Admiral Horatio Nelson decisively defeat the French Navy, stranding Napoleon Bonaparte’s army in Egypt and altering the course of world history. But what if things had been different? What if Earth Observation (EO) satellites powered by SPACE:AI had existed in that era? With timely actionable insights delivered from orbit, France might have had the upper hand, potentially reshaping the future of Europe, Africa, and even India.

From ground to greatness! Congratulations to the entire Lockheed Martin GPS III SV07 team on a successful launch. Yesterday, GPS III SV07 launched into orbit 12,550 miles above Earth from Cape Canaveral Space Force Station, but what's even more impressive is the journey it took to get there.   When military aircraft were redirected for hurricane relief, Lockheed Martin faced a 72-hour window to plan an alternative ground transport solution for this critical spacecraft. From mapping the safest routes to securing highway permissions, the team tackled every detail to ensure the spacecraft's safe journey. Then, after six days of navigating around Hurricane Milton and overcoming a few bumps in the road, GPS III SV07 arrived in Florida – right on time for a successful launch.   This launch was more than just your typical mission milestone – SV07 joins the United States Space Force’s ongoing GPS modernization effortsand underpins our ability to respond quickly to national security needs. We’re excited to see the impact GPS III SV07 will have on military and civilian operations around the world.   Read more on GPS III SV07's road to rapid launch: https://lnkd.in/gu-YrhHY   #GPS #RapidResponse #Space #Innovation

Last month, the 18th Space Defense Squadron added a satellite to the Satellite Catalog. Object 61446 is a fifth piece of a Vanguard launch from 1959! This makes me wonder where has it been all of this time, and how do they know what launch an item is from? One thing I looked at was - has it been maintained as an Analyst Satellite for a while? That appears to not be the case since there were no (I don't have a comprehensive list of Analyst Satellites, just a snapshot once in a while) obvious candidates. So I applied my RAAN Test to see if it has the same RAAN precession that the other two known pieces of that launch do - and it is close. The RAAN precession is very dependent on inclination so anything with a similar inclination will be close. Satellite number 11 is the payload and satellite number 12 is the upper stage. So far there have only been three unique TLEs (orbital parameters) released, this is not too unusual for a small piece of debris. I am gonna keep an eye on this object. Probably I should add that I graph the Right Ascension of Ascending Node for the various satellites (that is the RAAN Test) and contend that they should be nearly parallel IF they are actually from the same launch. Are these parallel enough? I am not sure. But at least it appears that 61446 is an actual object.

Earth orientation parameters (EOP) play a vital role in refining satellite tracking and orbit determination by accounting for Earth's rotation, polar motion, and other orientation changes. Spacebook offers high-precision EOP data derived from authoritative sources, including the International Earth Rotation Service and U.S. Naval Observatory.     Explore and download EOP data ➡️ spacebook.com    #Spacebook #SpaceSafety #EarthOrientationParameters #SpaceTechnology #SSA

🌊 𝗧𝗵𝗲 𝗜𝗻𝗰𝗿𝗲𝗱𝗶𝗯𝗹𝗲 𝗣𝗵𝗶𝗹𝗶𝗽𝗽𝗶𝗻𝗲 𝗠𝗮𝗿𝘀: 𝗔 𝗟𝗲𝗴𝗲𝗻𝗱 𝗼𝗳 𝘁𝗵𝗲 𝗦𝗸𝗶𝗲𝘀 𝗮𝗻𝗱 𝗦𝗲𝗮𝘀 ✈️🚤 The Philippine Mars, a marvel of aviation history, is not just a flying boat – it’s the largest operational seaplane in the world! Built by Martin Aircraft in the 1940s, this iconic aircraft still captures the imagination of aviation enthusiasts worldwide. 🚢 A True Workhorse of the Skies and Seas: Initially designed as a military transport during WWII, the Philippine Mars transitioned into civilian service as a water bomber, playing a vital role in fighting wildfires. Here’s what makes it legendary: ✅ Massive Capacity: Holds over 7,200 gallons of water for firefighting missions – that's an entire lake in the sky! ✅ Durability and Reliability: Known for its ability to land on water and endure tough conditions, making it a global firefighting asset. ✅ Heritage Status: Only a handful of Mars planes were built, and the Philippine Mars is the last of its kind still operational. 💡 Why It Matters Today: The Philippine Mars isn’t just a piece of history – it’s a reminder of how engineering and innovation can tackle critical challenges like wildfire management. Its massive water drops have saved countless lives, ecosystems, and properties. ➡️ Your Turn! What are your thoughts on this flying legend? Do you see modern applications for seaplanes like the Philippine Mars in today’s world? Let me know in the comments!

Transport Security International – Securing Maritime Borders with advancing technology According to NASA, there is about 372,000 miles (620,000 kilometers) of ocean coastline on planet Earth. That’s a lot of territory for customs, coast guards and military organizations to monitor and protect against unwanted intrusions. Put another way: there is more coastline on this planet than there is distance between the Earth and Moon. The distance between Earth and the Moon is a mere 238,855 miles (384,000 km) — a third less in length! To safeguard their coastlines, many nations turn to corporations who specialize in coastal surveillance, among other things. One of these companies is Airbus Defence and Space (airbus.com). For over 50 years, Airbus has helped monitor and protect some of the world and most critical maritime passages such as the Malacca Strait, the Panama Canal and the Suez Canal. Coastal surveillance “plays a critical role in managing and controlling a country’s territorial waters and economic exclusive zones,” said Alexis Latty, retired French Navy rear-admiral and an Airbus key account manager.   You can now also listen to the feature in a new PODCAST format via https://lnkd.in/e44TsbVR or DOWNLOAD the feature as a PDF via https://lnkd.in/esmBWQP8 If you open the feature via https://lnkd.in/esdneA_P you will see there is also a LISTEN button so you can have the full cover story read to you!

YASDE! (Yet Another #SpaceDebris Event) A #SpaceDebris-generating event has been reported by LeoLabs originating from the inactive Russian satellite RESURS P1 (US SATNO 39186, Int Des 2013-030A) Per LeoLabs, "a number of fragments were released" between 2024-06-26T13:05 UTC and 2024-06-27T00:51. (ref LeoLabs' post on X: https://lnkd.in/gYVzpkM7) ....and now the good news. The altitude is low, meaning the orbit lifetime of the debris should be rather short. ...and now the really good news. The altitude is even below that of all crewed missions: the International Space Station and Chinese Space Station (ref graphic - data courtesy of space-track.org). UPDATE: Event has also been reported by 18 SDS. Per space-track.org home page: "The 18th Space Defense Squadron (18 SDS) has confirmed the breakup of RESURS P1 (#39186, 2013-030A), which likely occurred June 26, 2024, between 1512-1640 UTC. As of June 26, 18 SDS is tracking 100+ associated pieces at an estimated 350 km altitude, which are being incorporated into routine conjunction assessment to support spaceflight safety. Analysis is ongoing." #LongTermSustainmentOfSpace #SpaceTrafficControl Office of Space Commerce
