Pulsed plasma rocket development accelerates manned missions to Mars

🚀 Gravity-1: The World's Most Powerful Solid-Fuel Rocket! Developed by Orienspace, the Gravity-1 is a solid-propellant expendable rocket that can carry up to 6.5 tons to LEO and 4.2 tons to SSO. With a height of 30 meters, a launch mass of 400 tons, and 600 tons of thrust, it made history with its first sea-based launch in early 2024. 🌍 Launching close to the equator offers key advantages for geo-synchronous satellites due to Earth's rotational momentum. However, near-polar, sun-synchronous orbits, often used for intelligence satellites, don’t benefit as much from low-latitude launches. 🚢 Could mobile, sea-based launch platforms like Gravity-1's be the future, serving both sun-synchronous and geo-synchronous orbits? Was Orienspace choice to launch from the sea driven by the increasing number of launches in launch facilities in China (67 in 2023) or is this a strategy with global potential? Could we see more launches from the sea in the future?  #RocketScience #Gravity1 #SeaLaunch #LaunchOperations

Did you know ?  Since the first satellite in 1957, thousands of satellites, rocket parts and other objects have contributed to an #orbital #junkyard !  New launchs for EO or telecommunication located in LEO can be compromised becaused of that. And with good reasons ! Debris can go up to 28000 km/h in Low Earth Orbit. There is a desperate need for solutions   👉Aldoria (formerly Share My Space) and Look Up Space are a good start for this problem. Both are developing a solution to monitore space and anticipate collisions threats 👉Astroscale and ClearSpace choose a different path. Both are developing solutions to clean space:  - Astroscale-Japan launched in February ADRAS-J to demonstrate the feasibility of locating and approaching large debris 🚀 - ClearSpace completed the preliminary design review for its CLEAR mission and its robotic arms that capture and deorbit defunct objects . Its first mission is set to be launched in 2026 to remove an old payload adapter from a Vega Rocket 👨🚀   We hope to see those innovations sooner than later !    #NetZeroSpace #NoDebris #CleanSpace #Innovation

At Mercury, the solar wind is 10 times stronger than at Earth. Meanwhile, Mercury’s internal magnetic field is 2000 times weaker than Earth’s. This creates a small, highly dynamic magnetosphere that manages to persist despite lacking several features typically associated with magnetospheric stability. #BepiColombo is set to explore Mercury’s magnetic environment with unprecedented detail once its two spacecraft achieve complementary orbits around the planet. 👇👇👇 This morning, #BepiColombo made its sixth close approach to Mercury (flying just 295 km above Mercury's surface). This final flyby will help slow the spacecraft and adjust its trajectory for entering orbit around the tiny planet in late 2026.

PSLV-C59/Proba-3: Two Spacecraft Dancing in Space! Have you ever imagined 2 spacecraft flying in perfect harmony 60,000 kilometres above Earth? But ISRO’s PSLV-C59/Proba-3 mission is making it a reality! Recently, PSLV-C59/Proba-3 was launched from SDSC-SHAR, Sriharikota. This mission demonstrates precise formation flying, a technique where the Coronagraph Spacecraft (CSC) and Occulter Spacecraft (OSC) will fly in space in a specific formation to block out the Sun’s bright light and observe its faint corona. This mission is not only a milestone for ISRO, but it also highlights the growing collaboration with ESA. Fun fact: it’s ESA’s first mission from Indian soil since 2001! 💡 Curious to learn more?

#Japanese JAXA: Japan Aerospace Exploration Agency successfully achieved the world's fastest optical inter-satellite communication speed of 1.8 Gbps between the #LUCAS Optical Inter-satellite Communications System and the Advanced Radar Satellite #Daichi4 (ALOS-4). Key Facts - - This is the world's first successful optical inter-satellite communication in geostationary orbit #LEO in 1.5μm wavelength band. - This is 7.5 times faster than the transmission speed of 240 Mbps of the previous generation Data Relay Test Satellite 'Kodama'. - In an emergency, commands can be sent from the ground to the satellite via a geostationary orbit satellite using LUCAS as a relay, and images can be obtained quickly. Future Ahead - 1.5μm band is a general-purpose wavelength used in terrestrial optical fiber communication networks; it can also be used in space communications in the future. - JAXA will conduct relaying observation and experiment data transfer from spacecraft orbiting at medium to low altitudes (200 to 1,000 km). If it succeeds, it will transform #spacecommunication. - The successful communication between LEO satellites and LUCAS is expected to increase communication time. - Even data acquired in areas where LEO satellites cannot directly communicate with a ground station can be transmitted to the ground in real-time via a geostationary orbit satellite. National Gain: Post-distance and relative positions experiments between the satellites, #JAXA can commercialize this #spacetech for better quality, quick & sustainable space communication.

YASDE! --> PRC CZ-12 rocket upper stage launched on 30 Nov 2024 (2024-226C/62187). 30 Nov 2024 saw the inaugural launch of China's two-stage kerosene/liquid oxygen-fueled Long March 12 (CZ-12) rocket which injected 2 satellites into a ~1000 km orbit, and YET ANOTHER SPACE DEBRIS EVENT. Thanks to the sharp eyes of commercial SSA company s2a systems, some 100 additional objects (presumably all #SpaceDebris?) were observed 15 hrs after the CZ-12 upper stage deployed the payloads (image below, ref LI post --> https://lnkd.in/gV2x--pn). This is yet another "low energy" debris event comparable to what has been seen with the CZ-6A upper stage (at least, when the CZ-6A does not catastrophically break up). WHAT IS HAPPENING? Some observers hypothesized these may be ice particles from the upper stage? Perhaps something associated with the passivation? (The ice hypothesis can seemingly be eliminated as debris has been observed > 10 days post launch). OBSERVATION BIAS. Are these PRC stages being preferentially observed, and in fact this is a frequent occurrence with many upper stages? (Or the nefarious view would say China is providing cover for clandestine payload deployments)? APPARENT OBJECT SIZES. While the signature (visual magnitude) of these objects has not been available, I'm estimating these objects are on the order of 15 visual magnitudes (15 mv), reasonable given the rate tracking and integration time. 15 mv at a range of 1500 km with a solar illumination angle of 90 deg translates into an albedo*area of some 0.0007 m^2 and when a standard albedo (reflectance) of 0.2 is assumed results in an object sizes in the single digit cm range (meaning unlikely to be detected by ground-based radar systems). At this higher altitude, the effects of drag are minimal, which precluded determining if the debris started to "lead" the rocket body due to the decreasing altitude of the fragments. (Meaning, a determination of the area/mass or ballistic coefficient without having a state solution). Speaking of which....leaving upper stages at 1000 km altitudes is now frowned upon, independent if they are littering up LEO with small fragments.
