Kenya launches first operational satellite into space

Posted by in categories: Elon Musk, food, satellites

NAIROBI, April 14 (Reuters) — Kenya launched its first operational earth observation satellite on Saturday onboard a SpaceX rocket from the United States, a live feed from Elon Musk’s rocket company showed.

The satellite, developed by nine Kenyan engineers, will collect agricultural and environmental data, including on floods, drought and wildfires, that authorities plan to use for disaster management and to combat food insecurity.

The Falcon 9 rocket carrying the Taifa-1 satellite, took off at about 648 GMT without incident from Vandenberg Base in California, after three postponements due to bad weather.

FAA gives OK for SpaceX’s Starship test flight from Texas

Posted by in category: satellites

CAPE CANAVERAL, Fla. — SpaceX has cleared the final hurdle for launching its new giant Starship from Texas as early as next week on a first test flight.

The Federal Aviation Administration issued the long-awaited license on Friday. SpaceX announced that Starship — the world’s biggest and most powerful rocket — could soar as soon as Monday.

No people or satellites will be aboard the 394-foot (120-meter) rocket. SpaceX will attempt to send the spacecraft atop the colossal booster around the world, from the southern tip of Texas all the way to Hawaii. The first stage will be discarded in the Gulf of Mexico and the spacecraft into the Pacific. No landings will be attempted for this debut.

SpaceX to launch Sateliot space base stations to provide satellite communications from smartphones

Posted by in categories: mobile phones, satellites

The Spanish company Sateliot plans to send its first base station into orbit, which will enable satellite communications directly from smartphones. SpaceX will help it do so. A SpaceX rocket will naturally be used to launch the telecom satellite into orbit.

Here’s What We Know

The company from Spain wants to launch five satellites into orbit by the end of this year. According to representatives of the startup, this first phase of the project will be completed. Sateliot wants to have 64 satellites in orbit next year, and the company plans to increase the number to 256 in 2025.

The most elusive black holes in the universe could lurk at the Milky Way’s center

Posted by in categories: cosmology, physics, satellites

— What’s the biggest black hole in the universe?

LISA will consist of a trio of satellites orbiting the sun that will constantly monitor the distances among them. When a gravitational wave comes by, the satellites will detect the telltale signature, like buoys in the ocean recognizing a passing tidal wave.

To search for IMBHs, the astronomers have to hope for a lucky break. If an IMBH in the galactic center happens to capture a wandering dense remnant (like a smaller black hole, a neutron star, or a white dwarf), the process will emit gravitational waves that LISA can potentially detect. Because the IMBH itself will be orbiting around the central supermassive black hole, these gravitational waves will undergo a Doppler shift (like the shifting in frequencies from a passing ambulance) due to the IMBH’s motion.

Report: U.S. military satellite antennas overdue for upgrades

Posted by in categories: government, military, satellites

WASHINGTON — The ground terminals used to operate U.S. military and intelligence satellites are running out of capacity and in dire need of upgrades, warns a new report from the Government Accountability Office.

GAO auditors spent more than a year investigating the state of the Satellite Control Network, operated by the U.S. Space Force. The network of 19 parabolic antennas, first established in 1959, is distributed across seven locations around the world.

The SCN is facing “obsolescence challenges and potential capacity gaps as DoD and other agencies launch more satellite systems that will rely on the network,” says GAO in the report released April 10.

How can we make the space sector more sustainable?

When talking about space, one might think about the stars one sees at night or a good sci-fi film. But space is also crowded with satellites, spacecrafts and astronauts, whose missions can last anywhere from several days to months. Meanwhile, 8,216 unmanned satellites revolve around Earth’s orbits to improve our daily lives. Communication satellites contribute to enhancing Internet access in regions deprived of infrastructure (so-called “white areas”); meteorology satellites have become essential for weather forecasts, while navigation satellites (including GPS) are crucial for current and future transportation needs such as automatic driving vehicles.

Technological advances in the sector have unlocked many new business opportunities. The industry can now launch constellations of thousand satellites to reach corners of the earth as it had never before (e.g., Starlink), while new markets such as space mining and space tourism are steadily growing. National champions (including the United States and France) have also framed the space sector as a top economic priority. It is thought the technological benefits accrued by companies such as SpaceX, Blue Origin or OneWeb, launched by billionaires such as Elon Musk, will also be able to trickle down to non-space sectors such as the energy or freight industries.

Dawn Aerospace.

In case you have not heard of them, Dawn Aerospace is one of the fastest-growing private space companies in the world, with clients from Europe, Asia, and the United States. They call themselves a “green” in-space propulsion supplier, and they also, to date, have around 11 operational satellites currently in orbit.

NASA’s DAGGER could give advance warning of the next big solar storm

Posted by in categories: materials, satellites

There’s enough trouble on this planet already that we don’t need new problems coming here from the sun. Unfortunately, we can’t yet destroy this pitiless star, so we are at its mercy. But NASA at least may soon be able to let us know when one of its murderous flares is going to send our terrestrial systems into disarray.

Understanding and predicting space weather is a big part of NASA’s job. There’s no air up there, so no one can hear you scream, “Wow, how about this radiation!” Consequently, we rely on a set of satellites to detect and relay this important data to us.

One such measurement is of solar wind, “an unrelenting stream of material from the sun.” Even NASA can’t find anything nice to say about it! Normally this stream is absorbed or dissipated by our magnetosphere, but if there’s a solar storm, it may be intense enough that it overwhelms the local defenses.
