NASA satellites detect signs of volcanic unrest years before eruptions
Thursday, 15 April 2021 10:16
Although there are telltale signs that a volcano is likely to erupt in the near future - an uptick in seismic activity, changes in gas emissions, and sudden ground deformation, for example - accurately predicting such eruptions is notoriously hard.
This is, in part, because no two volcanoes behave in exactly the same way and because few of the world's 1,500 or so active volcanoes have moni Concordia's Contained Confinement

All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes in a well-studied region of the universe. They publish their findings in two articles in the Stellar feedback and an airborne observatory; scientists determine a nebula younger than believed

In the southern sky, situated about 4,300 light years from Earth, lies RCW 120, an enormous glowing cloud of gas and dust. This cloud, known as an emission nebula, is formed of ionized gases and emits light at various wavelengths.
An international team led by West Virginia University researchers studied RCW 120 to analyze the effects of stellar feedback, the process by which stars inject e India's telecom regulator assessing Starlink system before accepting beta

Elon Musk's space company SpaceX recently launched its Starlink satellite internet service that claims to be capable of delivering 50Mbps to 150Mbps internet access to "any part" of the Earth under the sky. The global roll-out of this internet service is expected to be completed by 2022.
SpaceX has offered to pre-sell its Starlink satellite internet service in India, and the country's Depa Indonesian Govt deploys Iridium Push-to-Talk to overcome remote communications challenges

Iridium Communications reports that the Republic of Indonesia's government has adopted Iridium Push-to-Talk (PTT) devices to support communication efforts across the country. By fully deploying 500 Iridium PTT handsets, the Indonesian government now has a reliable "grab-and-go" real-time satellite communications solution, ideal for communications on-the-move applications across the country's div

Time keeping Space Development Agency could select three manufacturers to produce its next batch of satellites
Tuesday, 13 April 2021 22:42
WASHINGTON — The Pentagon’s Space Development Agency is considering buying its next 150 satellites from three different vendors, but that could change after the agency evaluates companies’ bids, SDA director Derek Tournear said April 14.
Speaking at the Washington Space Business Roundtable, Tournear said a request for proposals will be issued in August for the agency’s Transport Layer Tranche 1 — a network of hundreds of communications satellites in low Earth orbit projected to start launching in late 2024.
DoD space agency: Cyber attacks, not missiles, are the most worrisome threat to satellites
Tuesday, 13 April 2021 21:15
WASHINGTON — Intelligence agencies and analysts warn China and Russia are developing missiles that could strike U.S. satellites in low-Earth orbit. This will be a concern for the Pentagon’s Space Development Agency, which plans to deploy a network of satellites within range of those missiles.
Mock crew straps into space capsule, exits before liftoff
Tuesday, 13 April 2021 20:03
Jeff Bezos' Blue Origin company strapped two employees into a fueled rocketship for practice, but pulled them out shortly before sending the capsule to the edge of space Wednesday with only a test dummy.
The crew rehearsal in West Texas brings Blue Origin closer to launching tourists and others into space.
Blue Origin wanted to see how well a crew could get in and out of the capsule. The pretend astronauts also tested seatbelts and radio links before the 10 1/2-minute flight, and went back to the capsule following touchdown to climb aboard for recovery practice.
Blue Origin aces dress rehearsal for New Shepard crewed flights
Tuesday, 13 April 2021 17:57
WASHINGTON — Blue Origin completed another test flight of its New Shepard vehicle April 14, putting the company on the verge of finally flying people.
Blue Origin’s New Shepard vehicle lifted off from the company’s West Texas test site, known as Launch Site One by the company, at 12:51 p.m.
UAE to send rover to the Moon in 2022
Tuesday, 13 April 2021 14:58
Lunar exploration firm iSpace said Wednesday it will transport a United Arab Emirates unmanned rover to the Moon next year, as the Gulf state seeks to expand its space sector.
The UAE—made up of seven emirates including the capital Abu Dhabi and freewheeling Dubai—announced in September 2020 that it planned to launch the "Rashid" rover by 2024.
The rover "will be transported to the Moon on iSpace's lunar lander" during a mission in 2022, the Japanese company said in a statement.
Video: Drone test of Hera mission's asteroid radar
Tuesday, 13 April 2021 14:21
This drone hauled a model of the Juventas CubeSat high into the air, as a practical test of the antennas designed to perform the first radar sounding of the interior of an asteroid.
The shoebox-sized Juventas will be transported to the Didymos double-asteroid system by ESA's Hera mission. Once it flies freely in space, Juventas will deploy a cross antenna to perform a low-frequency radar scan up to 100 m deep within the smaller of the two asteroids, Dimorphos. Such low frequencies result in long wavelengths of around 6 m, too long for most indoor measurement facilities.
"To verify the antenna characteristics, we performed this aerial test with the support of the Hexapilots drone company," notes Martin Laabs of the Chair for Radio Frequency and Photonics Engineering of Technical University Dresden in Germany.
"For the most accurate measurements of the antennas' radiation properties, they had to be as far away as possible from other objects, so the Juventas model was hung 10 m down from the drone, which was flown up to 50 m into the sky.
