Lasers beam high-speed internet between cities through open air

Posted by in categories: internet, satellites

Alphabet’s floating internet venture Project Loon may have been deflated, but its legacy looks set to live on through a new effort called Project Taara. The team has salvaged the technology to deliver internet connectivity with lasers, demonstrating the viability in a new test between two cities separated by the Congo River.

Originally a Google side hustle before being spun off into its own project by parent company Alphabet, Project Loon had lofty goals of connecting remote regions to the internet by beaming lasers between high-altitude balloons. After years of successful trials however, the project was eventually grounded in January 2021 due to sky-high costs.

The balloons may have been a bust, but there’s still life in the lasers. After all, wireless optical communication systems could help connect communities where it’s not feasible to build complex grids of underground optical fiber cables, and where cellular or satellite internet is patchy or expensive.

SpaceX’s ‘Starlink’ To Provide Services To Mars For Starship, Confirms Elon Musk

Posted by in categories: Elon Musk, internet, satellites

Internet on Mars!!


Elon Musk’s ‘Starlink’ is currently providing services in parts of the US and Canada and has plans to enter India by the end of 2021. Tech mogul Elon Musk, via his recent tweet, revealed that his satellite broadband company ‘Starlink’ will extend its services to Mars. Musk informed about this idea while replying to a user’s tweet last week, as per reports by The Science Times. Currently, the broadband internet provider is undergoing public beta testing in parts of the US and Canada.

Starlink will strengthen Starship’s communication Musk’s idea came to light when a user asked if Starlink will be deployed between Earth and Mars to strengthen communication for Starship is SpaceX’s ambitious project that is being touted as the vehicle that will ferry cargo and crew to the red planet and back in the coming years. In response to the user’s tweet, Musk amplified the excitement with one word, “yeah”.

Space Force grappling with aging infrastructure used to operate satellites

Posted by in categories: government, military, satellites

WASHINGTON — The ground stations and tracking antennas the U.S. military relies on to communicate with its satellites — known as the Satellite Control Network, or SCN — are decades old and short of the capacity needed to keep up with the projected growth in space activities.

There are seven SCN sites located in the United States and around the world. About 15 large dish antennas at these sites command more than 190 military and government satellites in multiple orbits.

“Certainly the Satellite Control Network is a venerable system that’s been around for a long time. So we have multiple efforts ongoing to ensure that it’s ready for the future that we now find ourselves in,” Lt. Gen. Stephen Whiting, commander of the U.S. Space Operations Command, said last month at the 36th Space Symposium.

First Recorded Hurricane From Space Pushes Plasma Toward Earth’s Upper Atmosphere

Posted by in categories: climatology, satellites

Researchers recently found that a few years back, they “slept” through a hurricane. On analyzing weather satellite data from 2,014 scientists discovered evidence of a hurricane from space that pushed plasma toward Earth’s upper atmosphere. Though these events are invisible to the eye, the evidence reveals that they’re not uncommon. Understanding more about them could help to protect satellite and communications systems from disturbance and preserve radar and GPS output for life below on the planet’s surface.

Satellites in orbit around the planet gather immense amounts of data on environmental and climate activity. A recent publication in Nature Communications explains how the first hurricane from space was discovered through analysis of data gathered back in August 2014.

The research team looked at recently released files containing measurements taken by four satellites in the Defense Meteorological Satellite Program. From their analysis, the scientists created a 3D image that showed the hurricane from space forming features similar to what we’re familiar with in Earth’s lower atmosphere. A press release in Science Daily describes it as a gigantic spiral of plasma, with its arms swirling counterclockwise above the North Pole.

The Pentagon Wants to Launch a Nuclear Thermal Rocket in 4 Years

Posted by in categories: existential risks, military, robotics/AI, satellites

The spacecraft will provide fast transport between Earth and the moon—and beyond.


Picture this: World War III is just hours away. In the cold vastness of space, enemy robotic spacecraft are slowly adjusting their orbits and preparing to launch a surprise attack on the U.S.’s fleet of satellites. The uncrewed craft, with robotic arms strong enough to disable a satellite, are creeping up on American spacecraft, about to deal a knockout blow to the U.S. military.

But down on Earth, U.S. Space Force guardians have been keeping track of the assassin craft, knowing that in order to present as low a profile target as possible, they have just enough fuel for one attack. At the last minute, after the enemy satellites have committed to attack, the command activates the nuclear thermal propulsion (NTP) engines on the American satellites, quickly boosting them into a higher orbit and safely out of range.

Startup Launches Refueling Station Into Orbit, Gets $10 Million in Funding

Posted by in categories: energy, satellites

In June, San Francisco-based startup Orbit Fab launched a prototype refueling station into Earth’s orbit — but rather than allowing astronauts to venture into deep space, this system is meant to give old satellites a new lease on life.

That’s a compelling idea, and now the company has locked down $10 million in funding to further it. Our planet’s orbit is getting cluttered with old and new satellites, increasing the risks of a collision and adding to an existing space junk problem.

Orbit Fab’s Tenzing Tanker-001, an early prototype satellite fuel tanker, launched into orbit as part of SpaceX’s Transporter-2 rideshare mission on June 30.

SpaceX launches 51 Starlink internet satellites in the constellation’s 1st West Coast launch

Posted by in categories: internet, satellites

One of SpaceX’s oldest rockets launched on a historic 10th flight, carrying the first stack of Starlink satellites into space in more than two months before sticking a landing at sea to cap the successful mission.

The previously-flown Falcon 9 rocket blasted off from Space Launch Complex 4E at Vandenberg Space Force Station at 11:55 p.m. EDT (8:55 p.m. PDT, or 355 Sept. 14 GMT), marking the company’s 22nd launch of the year. It also marked a record 10th flight for this particular first stage booster.

SpaceX wins contract to launch weather satellite after ULA withdraws

Posted by in category: satellites

WASHINGTON — NASA has selected SpaceX to launch the last in a series of geostationary weather satellites that had previously been launched by United Launch Alliance.

NASA announced Sept. 10 that it awarded a contract to SpaceX for the Falcon Heavy launch of the Geostationary Operational Environmental Satellite (GOES) U spacecraft. The launch is scheduled for April 2024 from the Kennedy Space Center in Florida. The agency said the contract is valued at $152.5 million.

GOES-U is the fourth and final satellite in the GOES-R series of satellites, which monitor terrestrial and space weather from geostationary orbit. GOES-R launched in November 2016 and was renamed GOES-16, operating from the GOES East slot at 75 degrees west in GEO. GOES-S launched in March 2018 and became GOES-17, operating from the GOES West slot at 137 degrees west. GOES-T is scheduled to launch in January 2022 and will replace GOES-17 because of problems with that satellite’s main instrument, the Advanced Baseline Imager.

Scientists solve mystery of icy plumes that may foretell deadly supercell storms

Posted by in categories: climatology, satellites

When a cloudy plume of ice and water vapor billows up above the top of a severe thunderstorm, there’s a good chance a violent tornado, high winds or hailstones bigger than golf balls will soon pelt the Earth below.

A new Stanford University-led study, published Sept. 10 in Science, reveals the physical mechanism for these plumes, which form above most of the world’s most damaging tornadoes.

Previous research has shown they’re easy to spot in satellite imagery, often 30 minutes or more before severe weather reaches the ground. “The question is, why is this plume associated with the worst conditions, and how does it exist in the first place? That’s the gap that we are starting to fill,” said atmospheric scientist Morgan O’Neill, lead author of the new study.
