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.

NATIONAL HARBOR, Md. — Yahsat has selected SpaceX to launch its next-generation Thuraya mobile connectivity satellite in 2,023 the companies announced Sept. 8.

A Falcon 9 will launch the Thuraya 4-NGS satellite, being built by Airbus Defence and Space for UAE-based Yahsat, in the second half of 2023. The companies did not disclose terms of the launch contract.

Rocket Lab signed a five-launch contract with European satellite data company Kinéis. The deal adds to the space company’s backlog.

Private orbital debris removal company Astroscale has validated its magnetic capture system that is designed to tackle the problem of space debris. Its End-of-Life Services by Astroscale-demonstration (ELSA-d) servicer satellite managed to capture a simulated piece of space debris in orbit for the first time using the system.

Space debris is a serious and growing problem as popular orbits around the Earth become increasingly cluttered with defunct satellites, boosters, and other flotsam that present the hazard of an increased probability of a bit of debris striking a working spacecraft at hypersonic speeds.

The boom in LEO satellites will probably change the lives of customers who’ve struggled for high-speed internet—but only if they can afford it.

The biggest threat to our success is moving too slowly and refusing to change.

In June, a previously flown Falcon 9 booster lofted a new-generation Global Positioning Satellite for the US Space Force. This marked a watershed moment for the US military and the concept of reusable rockets, as the Space Force entrusted a satellite worth about half a billion dollars to the new technology.

Now, thanks to a recent news release from the US Space Force, we have a little more insight into why the Space Force is leaning into reusable rockets and other technology from innovative companies such as SpaceX.

Elon Musk, CEO of Tesla and SpaceX just confirmed that Starlink will transfer data close to speed of light. According to Gizmochina, the speed will be close to 97% speed of light.

Starlink is a constellation of thousands satellites aiming to deliver high-speed internet to consumers anywhere on the planet. While the Starlink service is still in beta, the company has over 100,000 users in 14 countries so far, with over half a million orders or refundable deposits placed by potential customers.

As of today there are 1,700 satellites in orbit. SpaceX intends to provide satellite internet connectivity to underserved areas of the planet, as well as provide competitively priced service in more urbanized areas. The company has stated that the positive cash flow from selling satellite internet services would be necessary to fund their Mars plans.

‘How far will future rockets go?’

The SpaceX Starship might be the next rocket to take humans to the moon, but it won’t be the first, and likely not the last.

Roaming isn’t available in space, so network access is an issue as satellites and spacecraft orbit the Earth. This will soon change as NASA develops a new Wideband Ka-band communications terminal, which is a transceiver that operates over government and commercial Ka-band spectrum allocations (17.7 GHz – 31 GHz).
