https://lnkd.in/dWzGH3rQ Extracts They had blasted off from Earth just an hour earlier, on 16 August. The 116 satellites onboard the launch vehicle were mostly designed and built by Western nations and businesses – but one of them was different. It was the first such spacecraft ever developed by the African country of Senegal. A small CubeSat called GaindeSAT-1A, it will provide earth observation and telecommunications services. Senegal’s president called it a big step towards “technological sovereignty”. The cost of launching a satellite has fallen significantly in recent years, says Kwaku Sumah, founder and managing director at Spacehubs Africa, a space consultancy. “That reduction in cost has opened the market up,” he adds. “These smaller nations… now have the opportunity to get involved.” To date, a total of 17 African countries have put more than 60 satellites into orbit and, along with Senegal, both Djibouti and Zimbabwe have also watched their first satellites become operational during the past 12 months. Dozens more African satellites are expected to go into orbit in the coming years. And yet, the continent currently has no space launch facilities of its own. Plus, powerful countries elsewhere in the world are arguably using nascent African space programmes as a means of building relationships and asserting their geopolitical dominance more broadly. Can more African nations chart their own way into orbit – and beyond? “It’s important for African countries to have their own satellites,” says Mr Sumah. He argues that it means better control over the technology and easier access to satellite data. This information could help Africans monitor crops, detect threats posed by extreme weather such as floods, or improve telecommunications in remote areas, he adds. Senegal’s new satellite was built by Senegalese technicians. While not wanting to detract from their significant achievement, it is worth noting that development of the satellite was made possible through a partnership with a French university, and that the spacecraft was launched on a SpaceX Falcon 9 rocket from California. Officials in both the US and China have considered the “strategic” implications of involving themselves in African space endeavours, says Julie Klinger, at the University of Delaware. “That does bring with it an intensifying need for updating global treaties and strategies around maintaining a peaceful and manageable space environment,” she adds. But there are opportunities, too. Dr Klinger notes that space launches from equatorial regions – which may not require as much fuel – could mean that African space ports have an important role to play in the coming decades.

One by one, the satellites -each of them encrusted with a hodge-podge of solar panels and other gizmos- detached from their mothership.

Business at her firm remains "very slow" overall, she adds. Given the massive threat posed to the continent by climate change, space tech should be used to monitor food and resources, she suggests. An African space race to reach the moon or Mars, in contrast, wouldn't be helpful: "We've got to look at the challenges that we have in Africa and find ways of solving those." For Sarah Kimani, of the Kenyan Meteorological Department, satellites have proved invaluable in helping her and her colleagues track dangerous weather conditions. She recalls using earth observation data provided by Eumetsat, a European satellite agency, to monitor a major dust storm in March. "We were able to tell the direction of this dust storm," she says. Later this year, she and her colleagues will begin receiving data...https://lnkd.in/e3Mud_m6 #SpaceTech #Markets #Economy

Senegal made history by launching its first satellite, GaindeSAT-1A, in August 2023. This CubeSat will offer earth observation and telecommunications services, marking a significant step toward technological independence. The falling cost of space launches has enabled smaller nations, like Senegal, to enter the space race, with 17 #African countries now having launched over 60 #satellites. Despite this progress, many African nations remain dependent on foreign #technology, while experts highlight the need for satellite programs to address climate challenges, such as monitoring crops and weather conditions. #Africa’s growing space sector is gaining geopolitical interest, with countries like the U.S. and China investing in local space programs. While this support has helped propel African technology into orbit, it raises concerns about foreign influence. However, some experts believe African nations can leverage competition between global powers to their advantage. With nearly 80 satellites in development across the continent, the future of Africa's space industry looks promising, with potential opportunities for local spaceports and further technological advancements.

[India Delays Launch of European Proba-3 Satellites To Dec. 5 To Create Artificial Eclipses In Space] A European mission that will use two satellites to create artificial eclipses in Earth orbit will now launch early Thursday morning (Dec. 5) after a delay, and you can watch the action live. The European Space Agency's (ESA) Proba-3 formation-flying mission is scheduled to lift off atop an Indian Polar Satellite Launch Vehicle (PSLV) from Satish Dhawan Space Center on Thursday at 5:42 a.m. EST (1042 GMT; 4:42 p.m. local time in India). The launch was originally scheduled to occur at 5:38 ET (1038 GMT) on Wednesday Dec.4, but the launch was scrubbed due to a technical issue. "During Proba3’s pre-launch preparations at the Satish Dhawan Space Centre in India, an anomaly in the redundant propulsion system of the Coronagraph Spacecraft occurred," ESA Director-General Josef Aschbacher said in a statement on social media. ESA and its private-sector partners began developing the 200-million-euro (about $210 million USD) Proba-3 mission back in 2014. It's the fourth flight in the agency's Proba series of low-cost, technology-demonstrating orbital efforts. The other three are Proba-1, an Earth-observation satellite with a novel hyperspectral instrument that launched in 2001; Proba-2, a sun-studying spacecraft with more than 20 technology and science payloads that took flight in 2009; and Proba-V, which launched in 2012 to map Earth's vegetation (the "V" in the mission's name) using innovative science gear. All of these predecessors are still going strong in Earth orbit. Proba-3 consists of two satellites, which together weigh about 1,210 pounds (550 kilograms). If all goes according to plan on Wednesday, the four-stage, 146-foot-tall (44.5 meters) PSLV will deliver this duo to a highly elliptical orbit, one that takes them 37,612 miles (60,530 kilometers) from Earth at their most distant point and just 373 miles (600 km) away at their closest. Then the mission's real work will begin a demonstration of formation flying, the likes of which we've never seen before. While aligned in this incredibly precise fashion, the Occulter will block the sun's disk from the Coronagraph's perspective, creating a total solar eclipse for the latter spacecraft. This will allow the Coronagraph to study the corona, the sun's wispy, unfathomably hot outer atmosphere, which is usually lost in our star's glare. Proba-3, which is expected to operate for at least two years, could therefore help scientists solve some sun mysteries, including why the corona is so hot and how the solar wind gets accelerated to such tremendous speeds. But the formation-flying technologies it will prove out may end up being the mission's most lasting legacy. Source: https://lnkd.in/gdUGhi7j #galaxyaerosgh #space #spaceexploration #SpaceNews

IELTS Task 2 Essay: The increasing frequency of satellite launches and space debris is becoming a threat to Earth. What are the main causes? What measures can be taken to address this? Model answer: With advancements in space technology, launching satellites has now become a less risky and highly successful endeavor, thus prompting nations to embark upon daring space missions using satellites at regular intervals. The result is an increasing accumulation of space debris owing to the humongous number of broken satellites or discarded rocket stages, which has now emerged as a grave menace to Earth. One of the primary factors that has been driving countries across the globe to be hell-bent upon satellite launches with an alarming frequency is the discernible improvements in space technology, which have now made satellite launches easier and more affordable. However, the negative repercussions of increasing the frequency of satellite launches cannot be overlooked. First, broken satellites, whose numbers are growing by day due to frequent space launches, give rise to the risk of collisions between a defunct satellite and an active communication satellite, which, if materialized, could create thousands of debris pieces orbiting the Earth. Secondly, as countries predominantly rely on satellites for an array of reasons ranging from weather forecasting to disaster warning and management, it has heightened the possibility of destruction of existing space infrastructure as the proportion of space debris increases by the day. For example, a conspicuous jump in the launch of satellites in recent decades with countries competing and racing against each other to occupy a domineering space in the domain of space technology and the resultant surge in space debris has thrown hundreds of functional satellites into disarray. However, the negative ramifications of the huge spurt in satellite launches and the concomitant spike in space debris can be effectively tackled through pragmatic measures. Devising a framework with the intent to regulate satellite launches by countries while ensuring responsible disposal of satellites and other spacecraft could be a decisive step in reducing space debris. Moreover, the investment in technologies for trackicng and removing orbital debris and fostering understanding among countries the treating the Earth's orbits as a precious common good could mitigate the threat from space debris. To conclude, while satellites offer a myriad of ostensible benefits to countries besides fueling their developmental aspirations, which explains the present momentous growth in satellite launches, their threat to Earth in the form of space debris and their possible devastating effects on active communication satellites is real and could be reduced by regulating satellite launches and making countries acknowledge and appreciate the importance of treating Earth's orbit as a common good.

?? The recent breakup of Intelsat 33E, is reminiscent of the 3 previous ones that occurred in the last 4 months. After the breakup of Resurs satellite on June 26th, the breakup of the CZ-6A upper stage followed on August 6th?in Low Earth Orbit, then an Atlas 5 upper-stage fragmentation occurred in Geostationary Transfer Orbit on September 6th, just one month before Intelsat 33E. Here's a look at the latest massive fragmentation in Low Earth Orbit, the breakup of the Chinese CZ-6A rocket body shortly after the launch of the first 18, of an expected 14,000 Chinese satellites in the Qianfan constellation, and its short-term consequences. The SYNAPSE screenshot below shows the Chinese Qianfan satellites (in green), evolving at the same orbital altitude and plan as hundreds of orbital debris (in red) generated by the fragmentation of the CZ-6A upper stage used to put them in orbit. ??? It all began with the launch of the first 18, over 14.000 satellites, of the Qianfan constellation by a Long March 6A launcher, abbreviated CZ-2A, on August 6, 2024. Below we can see how most of these satellites perform orbit raising, to reach their respective orbital position. These operations shall of course consider the collisions risks with fragments, derelict space objects and other operational satellites. Unfortunately, QIANFAN-7 (Norad 60385) has shown no manoeuvring capability since its orbit injection. If QIANFAN-7 is lost, it will be very bad news for space safety and sustainability. Firstly, because the satellite was inserted at an altitude of 800 km and will take much longer than the 25-year rule to re-enter. Secondly, because it highlights the relatively low reliability of the satellites of this future massive constellation. ?? Which are the short-term consequences of such break-up, for the space safety and sustainability? We provide a synthetic view of the collision risks induced by the debris of the CZ-2A fragmentation, since the day of the fragmentation, for typical operational screening parameters. It can be immediately noted that among the hundreds of collision risks detected since fragmentation epoch to October 24th, more than 80% are with space objects other than the fragments of CZ-2A Rocket body. ? ?? In parallel, and despite the collision risks incurred by the 18 Qianfan satellites, most of them perform the necessary orbital manoeuvres to progressively form this future constellation, supposed to be composed by 2030 of 14.000 satellites. Using proprietary algorithms, we can detect orbital manoeuvre performed by the satellites and follow their path to their operational orbit. As shown below, the Synapse's “pattern of life” feature enables analysis of a space object's orbiting behaviour throughout its lifetime. It allows to identify and evaluate changes in a satellite's orbit, and to record and analyse them over a user selected period.? Look Up Space : 360 ways to enable Space ???
