SpaceX aims to let astronauts avoid a radio blackout during re-entry

Artist’s impression of the uncrewed Orion capsule re-entering Earth’s atmosphere. The real thing returned safely to Earth in 2022 NASA SpaceX is about to test a system aimed at overcoming the communications blackout that happens when a spacecraft re-enters Earth’s atmosphere from orbit. Almost every spacecraft that has returned to Earth has suffered a break in communications during re-entry as the atmosphere slows it down. The same friction that decelerates the spacecraft also heats the air below the craft until it ionises into a glowing, conductive plasma. This quickly forms a… Source link

Network blackout cuts communications for millions in war-torn Sudan | Conflict News

All three of Sudan’s main internet providers are offline as the United Nations appeals for aid funds. All three of Sudan’s main internet operators were offline on Wednesday, internet observatory NetBlocks has said, cutting communications for millions of people stuck in conflict zones or fleeing for their safety. The network blackout could also freeze e-wallets that many people depend upon amid a widespread cash shortage. A source from the Rapid Support Forces (RSF) paramilitary has denied responsibility, the Reuters news agency reported, and the companies have not publicly blamed anyone for the outages. Two of the networks had been offline since Friday, when telecom sources and the army-aligned state news agency said the RSF had shut down the networks belonging to MTN Sudan and Sudani. Zain Sudan is now also offline, NetBlocks said. Aid agencies have warned of rising hunger in Sudan and famine-like conditions in some areas, as a result of the nine-month war between the Sudanese army and paramilitary RSF. The United Nations on Wednesday urged countries not to forget the civilians caught …

Blackout in Gaza’s Al-Aqsa Hospital as fuel runs out, babies at high risk | Israel War on Gaza News

Israeli military attacks in the vicinity have left patients and medical staff to an uncertain fate. A total blackout at the Al-Aqsa Martyrs Hospital in central Gaza, one of the last functioning medical facilities in the enclave, has put the lives of its most vulnerable patients at risk with no fuel left to power generators and as the Israeli military was attacking areas nearby. “We’re trying to work with what we have. But we will have to stop working completely, because we don’t have any electricity,” one doctor at the hospital told Al Jazeera. “There’s a complete outage so how can we treat the patients?” Particularly at risk were premature and newborn babies, as well as patients in intensive care units. Gaza’s Government Media Office in a statement said they were at extreme risk of death. Earlier footage showed medical staff in dark rooms trying to work with flashlights. “We worked on the light of mobile phones to take care of the condition of children in intensive care, and the devices work on secondary power, …

Gaza is Facing Yet Another Communications Blackout

Gaza is Facing Yet Another Communications Blackout

The Gaza Strip was plunged into another communications blackout on Friday, with internet and phone service cut off for most of its more than two million residents as Israeli bombardment continued. “All telecom services in Gaza Strip have been lost due to the ongoing aggression,” the major Palestinian telecommunications company, Paltel, announced late Friday afternoon. Another mobile network, Ooredoo Palestine, said damage to communications lines had shut down all of its services in the southern and central parts of the territory, which Israeli forces have recently made a focus of their operations. The Israeli military did not immediately respond to the reports. The blackout was confirmed by NetBlocks, an internet monitoring group, which said the internet outage was “near-total” and that landline, cellular and wireless internet service was likely unavailable to most residents in Gaza. The Palestine Red Crescent Society, which provides emergency medical aid and ambulance services, said it had completely lost contact with its teams in Gaza and that the blackout had exacerbated the difficulty of reaching injured people promptly. This is the …

Internet access in Gaza partially restored after blackout

Internet access in Gaza partially restored after blackout

After a weekend of almost complete internet blackout, connectivity in Gaza has been partially restored. On Friday, internet monitoring firms and experts reported that access to the internet had significantly degraded in the Palestinian enclave. The local internet service NetStream “collapsed,” according to NetBlocks, a firm that tracks internet access across the world. At the same time, IODA, another internet monitoring system, showed outages and degradation across several Palestinian internet providers. The lack of internet communications caused emergency lines to stop ringing, made it hard for paramedics to locate the wounded, and for family members to reach relatives and friends, according to The New York Times. On Sunday, IODA reported “marginal restoration” of internet connectivity in Gaza. Abdulmajeed Melhem, chief executive of the Palestinian main telecommunications company Paltel Group, told The Times that the internet had come back even though the company had not made any repairs. Then on Monday, Gaza had roughly the same access to internet connectivity as before Friday, according to several experts and firms that are monitoring the internet in the …
