AMSAT OSCAR-7 fiftieth Anniversary – A Testbed for Saving Lives
As we observe AMSAT OSCAR-7’s fiftieth anniversary because the oldest working satellite tv for pc, we must always recall what could also be its most noteworthy accomplishment.
OSCAR-7 was used to analyze the potential for finding downed plane and disabled sea vessels by utilizing Doppler evaluation of alerts from emergency location transmitters (ELT’s).
As envisioned by spacecraft engineers from america and Russia, the idea was to relay alerts from beacon units, ELT’s or emergency location transmitters, already put in on giant and small plane and on ships and smaller vessels geared up with EPIRB’s or Emergency Place-Indicating Radiobeacon Stations. These one-way beacon transmitters, initially supposed to be obtained by floor rescue events, is also obtained and transponded by a LEO spacecraft, drastically extending the rescue potential.
The alerts is also Doppler tracked, one-way, by processing the beacon uplink sign on-board the spacecraft. This is able to enable the spacecraft to search out the supply beacon’s location instantly. This is able to enable the emergency beacon to be recognized and positioned and the place saved for fast downlink on the subsequent obtainable floor station. We all know it’s exhausting to recollect however this was in an period earlier than the creation of GPS!
Scientists from the Russian COSPAS (Russian acronym for “Area System for the Search of Vessels in Misery) and the U.S. SARSAT (Search and Rescue Satellite tv for pc) groups simulated ELT’s on beginner radio stations and demonstrated how receiving and relaying ELT transmissions and analyzing Doppler shift as OSCAR-7 handed overhead may precisely find the emergency beacons.
The checks had been extremely profitable. The COSPAS/SARSAT program went forward and has been operational since 1982. From that point till 2021, when this system merged with others offering comparable functionality by way of LEO, MEO and GEO spacecraft, this system had saved the lives of 57,413 individuals in 17,663 separate rescue occasions, involving downed plane and ships at sea.

SpaceX Dragon Fires Thrusters to Enhance ISS Orbit for the First Time
For the primary time, SpaceX’s Dragon spacecraft efficiently raised the orbit of the Worldwide Area Station (ISS) by firing its thrusters. The orbital enhance marks a big milestone in Dragon’s capabilities and comes as a part of SpaceX’s thirty first industrial resupply mission to the ISS. The mission, which launched on November 4, delivered a Dragon cargo automobile which docked with the station the next day. On November 8, the automobile performed an orbit-raising maneuver, stabilizing the ISS’s place in low-Earth orbit.
Orbit-raising maneuvers are routine for the ISS, which requires common boosts to counteract orbital decay attributable to Earth’s gravity. Till now, this activity has been dealt with primarily by Russia’s Soyuz and Progress automobiles, alongside occasional boosts from different spacecraft. With Dragon now performing such maneuvers, the U.S. spacecraft has added a important functionality, particularly vital as NASA prepares for the eventual decommissioning of the ISS. The info gathered from right this moment’s maneuver will support within the growth of SpaceX’s future ISS deorbit automobile, often known as the U.S. Deorbit Automobile, which NASA has contracted to information the station into the Pacific Ocean upon its retirement.
The reboost started at roughly 12:50 p.m. ET (1750 UTC) and lasted round 12.5 minutes, elevating the station’s orbit barely. NASA monitored the reboost carefully and shared updates on social media platform X, noting that Dragon’s efficiency in its first orbit-raising activity was “ demonstration” of its rising capabilities. SpaceX intends to use the maneuver’s information towards the design of the deliberate U.S. Deorbit Automobile, scheduled for use as soon as the ISS reaches the tip of its operational lifespan.
This latest success by Dragon isn’t the primary occasion of a U.S.-made spacecraft boosting the ISS. In 2022, NASA examined an identical maneuver utilizing a Northrop Grumman Cygnus cargo automobile. Nevertheless, the info collected from Dragon’s maneuver holds distinctive significance, because it instantly informs the planning of the ISS’s managed deorbit mission. The spacecraft, which has been constantly occupied for almost 25 years, is anticipated to stay operational till round 2030, when the prices and upkeep calls for of the growing old construction will probably result in its retirement.
The ISS’s eventual decommissioning aligns with NASA’s shift in the direction of industrial partnerships in low-Earth orbit. The company envisions that new, privately operated area stations will change the ISS as analysis outposts, enabling NASA to focus its price range on deeper area exploration, together with the Artemis Program’s return to the Moon. With the ISS contract awarded to SpaceX, the company has positioned its belief within the personal sector to develop the know-how wanted to securely conclude the station’s mission in a managed method.
The success of Dragon’s reboost maneuver additionally underscores the U.S.’s lowered reliance on Russian spacecraft to keep up ISS operations. Regardless of world political tensions, notably since Russia’s 2022 invasion of Ukraine, the U.S.-Russian partnership on the ISS has persevered. Nevertheless, Dragon’s demonstrated potential to carry out reboosts affords NASA an alternate if wanted. Since Dragon started launching U.S. astronauts in 2020, SpaceX has supplied NASA with a dependable launch choice from American soil, and now it has confirmed able to supporting the station’s orbit, a job important to the ISS’s long-term stability.

SEAQUE Quantum Tech Arrives at ISS for Groundbreaking Demo
The Area Entanglement and Annealing QUantum Experiment (SEAQUE) has formally arrived on the Worldwide Area Station (ISS), delivered aboard NASA’s SpaceX CRS-31 mission. The SpaceX Dragon capsule docked with the ISS on November 4th, carrying over 6,000 kilos of scientific investigations and cargo, together with SEAQUE. Deliberate for set up on the Nanoracks Bishop airlock, SEAQUE represents an necessary step ahead in constructing a world quantum communications community.
Quantum computer systems promise computation speeds which are exponentially sooner than typical computer systems, and distributed quantum sensors might result in new understandings of Earth and our place within the universe by measuring minute adjustments in gravity. Nevertheless, to totally harness these skills, a devoted communication community should be established, able to linking quantum computer systems and sensors no matter their location. SEAQUE’s experiment goals to show the viability of orbiting nodes that may securely transmit and obtain quantum information to and from the bottom by way of free-space optical communications.
A cornerstone of SEAQUE’s mission is to check an built-in supply of entangled photons, a important requirement for safe quantum information transmission. Entangled photons are uniquely interconnected, the place measuring one immediately influences the opposite, no matter distance. This property permits potential information transmission that’s safe and intensely troublesome to intercept. Not like prior quantum experiments that used bulk optics, SEAQUE makes use of a waveguide-based photon supply. This innovation is extra compact, environment friendly, and resilient, eliminating the necessity for handbook optical realignment post-launch.
“SEAQUE will reveal a brand new and never-before-flown entanglement supply primarily based on built-in optics,” mentioned Paul Kwiat, principal investigator on the College of Illinois Urbana-Champaign. He emphasised that the know-how is pivotal for scalable world networks, as handbook changes could be impractical when managing a whole bunch of quantum nodes unfold throughout continents. Makan Mohageg, SEAQUE co-investigator from NASA’s Jet Propulsion Laboratory (JPL), bolstered that SEAQUE’s success would pave the best way for future, widespread quantum networks.
An added factor of SEAQUE’s demonstration includes testing its potential to self-heal from radiation injury, a persistent problem in area. Excessive-energy particles can impair the detectors that obtain quantum alerts, inflicting noise and, ultimately, failure. SEAQUE will make use of a vivid laser to periodically restore such injury utilizing a method often known as annealing. This course of has proven success on the bottom, “effervescent away” defects and lowering noise to increase detector life.
The SEAQUE mission displays a really worldwide effort, together with consultants and college students from the College of Illinois Urbana-Champaign, the College of Waterloo in Ontario, Canada, the Nationwide College of Singapore, and industrial companions resembling AdvR, Inc., and Nanoracks. Funded by NASA’s Organic and Bodily Sciences Division, SEAQUE is anticipated to drive breakthroughs in safe quantum communications, establishing a basis for future developments in long-distance information sharing.
