In recent years, #rideshares have become evermore common. While it provides a unique opportunity for new players to enter the realm of #spaceoperations, it also comes with its challenges. 🚀 Shortly after launch, objects will travel closely together in dense clusters. Finding and identifying a specific spacecraft in such a group is...tricky, and there is a high risk of a satellite getting “lost”. For example, the video shows the spread of 53 satellites and the Falcon 9 upper stage of #SpaceX #Transporter-10 launch after orbital insertion. The objects are grouped into multiple clusters that get slowly dispersed. #spacetrack published orbits 9 days after the Transporter 10 launch. With the increased traffic in #LEO, one also needs to be ready to perform #collisionavoidance starting from day one. Getting support during the Launch and Early Operations Phase is crucial to ensure a smooth transition into regular #operations. Dedicated tracking based on #SST sensors can lead to earlier availability of orbits, decrease the risk of losing a satellite, and allow earlier collision avoidance service. Do you have a launch coming up? Let's talk https://lnkd.in/dpT6XV-y #OKAPIOrbits #FeatureFridays #LEOP #launches #satellitelaunch

Face to face with Sun-eclipsing Proba-3 Through exquisite, millimetre-scale, formation flying, the dual satellites making up ESA’s Proba-3 will accomplish what was previously a space mission impossible: cast a precisely held shadow from one platform to the other, in the process blocking out the fiery Sun to observe its ghostly surrounding atmosphere on a prolonged basis.

Non Earth Imaging is like Magic. Satellites are now imaging other Satellites to know their capabilities.This is how it works. Till a few years ago, people were really afraid if other objects were in their satellite’s path for even like 100km distance. But today because there are many “space objects” - for which we have no idea what they do - something is wrong with the object and we want to know what This is all a part of Space situational awareness. Today satellite operators like HEO are using their imaging satellites to quitely swing around other satellites and image them. The below attached is a picture of ISS from as close as 60KM from a HEO satellite. Crazy where the world is going. 🚀🚀

🚀 In episode 4 of The Orbiter, Spire CEO Peter Platzer dives into the extraordinary versatility of ‘listening’ satellites. From measuring the temperature of the ocean to identifying a GPS jammer and more, ‘listening’ satellites are able to capture extremely different phenomenon in different modalities simply by software. 🎥 Watch now #TheOrbiter #satellites #ListeningSatellites

COMSPOC's Number of Encounters Assessment Tool (NEAT) is a FREE, innovative tool for assessing collision risks in space. It uses a fast, probability-based algorithm to calculate the long-term encounter rate between satellites. Users can adjust parameters like constellation size, orbit altitude, and inclination, and set thresholds for warnings, maneuvers, and collisions. NEAT is suitable for circular, elliptical, and relatively-inclined orbits, aiding in the assessment of proposed constellations' impact on encounter rates. ⚠️🛰️🌌 For a comprehensive understanding of NEAT's capabilities and detailed information, click here: https://lnkd.in/dJaf5uRH

✨ Satellites are silent observers, orbiting Earth and exploring the vast universe beyond. They gather crucial data on weather, climate, and space, helping us understand both our planet and distant galaxies. ✨ These tireless explorers reveal the mysteries of the cosmos, from tracking storms to capturing breathtaking images of stars and planets. Satellites also play a key role in global communication, connecting people across the world. ✨ By quietly collecting and transmitting information, they bridge the gap between Earth and the unknown, expanding our knowledge of the universe. 🌍🛰️✨ #Satellite #SpaceExploration #Universe

Get to know the instruments that will fly on the Metop Second Generation satellites.

Keep getting these postcards about traveling to the moon. Wondering what time it is there anyway. And how do you know when you get there. It's all about GPS. A thought experiment Uncle Travel Traveling Matt and I have been working through has to do with GPS in outside space. Once you are above the GPS satellites, how do you know where you are at relative to outside space and other objects within the region. It seems that it would very much be possible to implement a High Earth Orbit or a locally deployable positioning system. You are going to need one. What would it look like, ships, satellites. Were the grids like freeways... What time is it on the moon? NIST proposes an answer https://lnkd.in/dkzdedVV?

NanoMagSat and Tango Scout missions get go-ahead, Further embracing the New Space era, ESA is to develop two new Scout satellites: NanoMagSat and Tango. NanoMagSat will measure Earth’s magnetic field to help assess space weather hazards and continue on from ESA’s current Swarm mission. Tango will measure greenhouse-gas emissions from human activity and complements the upcoming Copernicus Carbon Dioxide Monitoring mission and the Sentinel-5 mission, as well as the current Sentinel-5P mission., : Further
