Rocket company develops massive catapult to launch satellites into space without using jet fuel: ‘10,000 times the force of Earth’s gravity’

Posted by in categories: energy, health, satellites

SpinLaunch was founded in 2014, and its leadership team has since raised tens of millions of dollars in funding. The company has been working with NASA, Airbus, and Cornell University, launching some of their equipment as part of testing. The tech has so far endured 10,000 Gs, “10,000 times the force of Earth’s gravity,” all per the Space.com report.

If SpinLaunch’s concept proves reliable, it could eliminate the loads of fuel that is burned to launch spacecraft. In 2016, Business Insider noted that SpaceX’s Falcon 9 rocket used more than 900,000 pounds of propellant for each liftoff, for reference. The fuel efficiency may have improved some since then.

ESA Satellites Detect Mysterious Gamma-Ray Burst in Nearby Galaxy

Posted by in categories: computing, satellites

As ESA’s satellite INTEGRAL scanned the skies, it detected a surge of gamma-rays emanating from the nearby galaxy M82. Shortly after this observation, ESA’s XMM-Newton X-ray space telescope sought any residual glow from the event but detected nothing. An international research group, with contributors from the University of Geneva (UNIGE), concluded that the burst was an extragalactic flare from a magnetar, a young neutron star known for its intense magnetic field. This finding was documented in the journal Nature.

On 15 November 2023, ESA’s satellite INTEGRAL spotted a sudden explosion from a rare object. For only a tenth of a second, a short burst of energetic gamma-rays appeared in the sky. “The satellite data were received in the INTEGRAL Science Data Centre (ISDC), based on the Ecogia site of the UNIGE Astronomy Department, from where a gamma-ray burst alert was sent out to astronomers worldwide, only 13 seconds after its detection,” explains Carlo Ferrigno, senior research associate in the Astronomy Department at UNIGE Faculty of Science, PI of the ISDC and co-author of the publication. The IBAS (Integral Burst Alert System) software gave an automatic localization coinciding with the galaxy M82, 12 million light-years away. This alert system was developed and is operated by scientists and engineers from the UNIGE in collaboration with international colleagues.

Missile Defense Agency satellites track first hypersonic launch

Posted by in categories: military, satellites

The constellation will eventually include 100 satellites providing global coverage of advanced missile launches. For now, the handful of spacecraft offers limited coverage. SDA Director Derek Tournear told reporters in April that coordinating tracking opportunities for the satellites is a challenge because they have to be positioned over the venue where missile tests are being performed.

He noted that along with tracking routine Defense Department test flights, the satellites are also scanning global hot spots for missile activity as they orbit the Earth.

The flight the satellites tracked was the first for MDA’s Hypersonic Testbed, or HTB-1. The vehicle serves as a platform for various hypersonic experiments and advanced components and joins a growing inventory of high-speed flight test systems. That includes the Test Resource Management Center’s Multi-Service Advanced Capability Hypersonic Test Bed and the Defense Innovation Unit’s Hypersonic and High-Cadence Airborne Testing Capabilities program.

Segway’s robot mower spared me from my least favorite chore

Posted by in categories: robotics/AI, satellites

I’m sure some of you have looked at robo mowers as Roombas for your yard but, sadly, many of them require you to install a boundary wire around the perimeter of your lawn. And any product that requires you to dig a trench is the opposite of what “low effort” means to me. That’s why I was interested in trying Segway’s Navimow i105, its £945 (around $1,200) GPS-equipped mower which eliminates that busywork. And keeping your lawn neat and tidy is a job that’s all busywork.

Ask a gardener and they’ll tell you the secret to a great lawn is to seed a piece of flat land and then mow it into submission. Regular, militant mowing kills off all the other flora, ensuring only grass can grow until everything looks well-manicured. But that relentless mowing requires a lot of time, a luxury I’ve never had. It’s the sort of job a robot mower was born to do, given it can scuttle around and trim grass without you there.

Segway’s i Series is the company’s latest, more affordable offering compared to its pricier S Series. The new units have a smaller battery and range, with the i105 able to handle areas up to 500 square meters. Unlike some GPS mowers, the i105 is equipped with a forward facing HD camera with a 180-degree field of vision. So while it relies on satellites for positioning, it’ll have enough sense to stop before it clatters into an obstacle. It’s not packing sophisticated computer vision smarts, but it’ll play safe lest it charge into a pet, inattentive family member or prized flower.

Satellite data reveal electromagnetic anomalies up to 19 days before 2023 Turkey earthquake

Posted by in category: satellites

Earthquakes may betray their impending presence much earlier than previously thought through a variety of anomalies present in the ground, atmosphere and ionosphere that can be detected using satellites, a recent study in the Journal of Applied Geodesy suggests.

Plasma Physicist Warns That Elon Musk’s Disposable Satellites May Be Damaging the Earth’s Magnetic Field

Posted by in categories: Elon Musk, satellites

Dead satellites and other debris are constantly burning up as they fall out of Earth’s orbit.

Conventional wisdom is destroying all that space junk is good, because it keeps orbit less cluttered. But it may have harmful effects on our planet’s magnetic field, as plasma physicist and former Air Force research scientist Sierra Solter — the author of a contentious and yet-to-be-peer-reviewed paper — argues in a new essay for The Guardian.

Ventures like Elon Musk’s SpaceX are launching thousands of satellites into orbit, and tens of thousands more are soon to follow as interest in the private space industry and space tourism continues to grow.

Vandenberg SFB Sees Third Launch of Week with SpaceX Rocket’s Liftoff

Posted by in categories: internet, satellites

SpaceX continued expanding the Starlink constellation’s direct-to-cell capabilities by sending another 13 satellites plus seven others into orbit aboard a Falcon 9 rocket launched early Saturday from Vandenberg Space Force Base.

The 20 new Starlink satellites, including a baker’s dozen with direct-to-cell capabilities, lifted off at 5:58 a.m. Saturday as a stubborn marine layer interfered with those hoping to see it.

After completing its tasks, the first-stage booster, making its 21st flight, landed on the Of Course I Still Love You droneship positioned in the Pacific Ocean hundreds of miles south of the base. Saturday’s mission marked the 301st successful Falcon landing.

Planet’s first hyperspectral satellite is ready to launch

Posted by in category: satellites

TAMPA, Fla. — Planet’s first hyperspectral satellite is ready for launch to help push the Earth observation operator to profitability by early next year.

Tanager-1 has arrived at California’s Vandenberg Space Force Base ahead of a SpaceX rideshare mission that could take off as soon as July, the operator said June 6 amid earnings results.

Will Marshall, Planet’s co-founder, CEO and chair, told investors the 30-meter resolution satellite will augment its optical constellation by collecting data in more than 400 spectral bands to capture phenomena invisible to the human eye.
