China's "Spaceplane #3" (NORAD 58573) continues to maintain an orbit altitude of ~ 605 km, but with recent small maneuvers evident: * 13 Mar 24: orbit raising * 16 Mar 24: orbit lowering * 28 Mar 24: orbit raising #ProtectAndDefend (Orbital data sourced from space-track.org and used with permission per ODR 24-002-4).

[GalaxySpaceNewsGH: ASRI Unveils New Suborbital Sounding Rocket Launch Facility] In a significant milestone for South Africa’s space industry, Aerospace Systems Research Institute (ASRI) engineers have commissioned a cutting-edge suborbital sounding rocket launch facility at the Denel Overberg Test Range (OTR) in the Western Cape. Funded by the Department of Science and Innovation (DSI), this facility is the first of its kind in the country, marking the most significant piece of space launch infrastructure constructed since the establishment of South Africa’s democracy. The new facility includes a launch gantry capable of accommodating suborbital rockets like ASRI’s Phoenix hybrid rocket, which was tested during the facility’s cold-flow propellant trial. This trial evaluated ASRI’s launch control software, ensuring smooth communication between the control room and the rocket during future launches. https://lnkd.in/eYbJYyf8 #galaxyaerosgh #space #spaceexploration #SpaceNews

China quietly breaking records* with Shiyan 25 (SY-25) very low earth orbit (VLEO) satellite. SY-25 has now sustained operations at an altitude of 271 km since early Sept 2023, or more than 5 months (ref graphic). Launched 20 June 2023, China state media's only disclosure on SY-25 is "this satellite will mainly be used to carry out new Earth-observation technology experiments." (SY-25 is NORAD 57047). Meanwhile, the Chinese commercial and overtly VLEO satellite QianKun-1 (QK-1) continues its slow descent - currently at 349 km (QK-1 is NORAD 57422, Int Des 2023-103B). #VLEO (Orbital data sourced from space-track.org and used with permission per ODR 24-002-4). * Update: ESA's GOCE mission flew at an altitude of 254 km for more than 3 years, followed by a shorter duration at 224 km.

Radiation shielding is crucial for crewed missions beyond Earth orbit, such as trips to Mars, where astronauts face higher levels of cosmic radiation. Effective shielding materials and spacecraft design are being developed to minimize health risks, including increased cancer risk and organ damage. Innovative solutions like water tanks and advanced materials are being explored to create effective barriers against radiation. Mission planning also considers scheduling missions during periods of lower solar activity to reduce exposure to solar energetic particles. These efforts are vital to safeguarding the health and safety of astronauts during long-duration space missions. https://lnkd.in/ei2yx-U5 #galaxyaerosgh #space #spaceexploration #SpaceNews

Peculiar. "I'm not dead yet!" PRC appears to have had at least some success recovering the surprise cislunar mission DRO-A/B. While the YZ-1S upper stage may have underperformed, additional maneuver(s) have now occurred. Odd that space-track.org has an updated apogee/perigee - but no corresponding TLE reflecting this new orbit (not that legacy SGP4 would do much good in this orbit). #xGEO #cislunar #SpaceDomainAwareness (Orbital data sourced from space-track.org and used with permission per ODR 24-002-4).

Boost to land-based connectivity as Hanwha Phasor launches enterprise-grade flat-panel satellite antenna for mobile communications Hanwha Phasor has announced it will release its land antenna, for mobile communications, the Phasor L3300B, to the market in Q3 of 2024. The Phasor L3300B is an active electronically steered antenna (AESA) which has been developed for commercial and military use. This announcement marks the first time that Hanwha Phasor’s land antenna solution will be available for commercial and defence use, offering users uninterrupted communications regardless of the environment. This is as a result of dual simultaneous receive channels, meaning the antenna can form connections with new satellites before breaking its current connection. With conflict in mainland Europe and the Middle East, and a growing number of natural disasters each year – the necessity for uninterrupted communications has never been more pressing. Hanwha Phasor’s new product helps fill this gap. The product provides the highest levels of connection, operating in Ku-Band, and is able to connect to both Geostationary Satellites (GEO) as well as the Low Earth Orbiting (LEO) constellations, and is compliant with OneWeb and developed to be compatible with leading providers. #Antenna #Satellite #MobileCommunication #Telecommunications #SatelliteCommunications #Defense #AntennaTechnology #Security #Emergency #Ambulance #SpecialForces #SOF #Media https://lnkd.in/g-uWA_xD

Adapting to Challenges: discover Israel's unique route to satellite launch While most nations launch satellites eastward to harness the Earth's rotational momentum, Israel charts its own course driven by unique geographic and security considerations. Conventional eastward trajectories pose risks - a failed launch could scatter debris over populated Israeli areas or enemy states' territories, compromising sensitive technologies. To address this challenge, Israel's Ofek satellite series takes an unconventional westward path, launching against the Earth's rotation into retrograde orbits. This counterintuitive approach demanded ingenuity from Israeli scientists, who overcame immense resistance to develop some of the world's smallest and most cost-effective satellite designs! The westward launch trajectory exemplifies the pioneering spirit and problem-solving prowess of Israel's Space and Satellite Administration in the face of complex challenges.

The precipitous orbit decay of the new "OBJECT C" (59022 / 2022-209C) originating from COSMOS 2574 (58658 / 2023-209A) a few days ago is indicative of high area/mass and likely #SpaceDebris. (Orbital data sourced from space-track.org and used with permission per ODR 24-002-4).

Ever wondered why Despite having Anti Satellite Capabilities No country in the world ever uses it against other? - Well the answer is simple they can't afford to attack the satellites because if they do they will get harmed as well . When a satellite is destroyed in space, it generates debris ,thousands of pieces of hardware that can orbit #Earth 🌏at extremely high speeds (upto 28,000 km/h),& this High Speed rotating debris will further can collide with your own Satellite 🛰️ & destroy it. 🔸NOTE :This is the exact reason why even countries that have demonstrated ASAT Capabilities [ #India 🇮🇳,#China 🇨🇳, #USA 🇺🇸& #Russia 🇷🇺 ] have destroyed Satellites in 'Lower Earth Orbit' which is relatively close to Earth (typically 300 to 1,200 km above the surface).At this altitude, debris from a destroyed satellite will eventually re-enter Earth's atmosphere and burn up within a few months or years due to atmospheric drag. This helps reduce the long-term risk of debris collisions with other satellites.
