Water Plasma Propulsion tested successfully in Space

Posted by in categories: innovation, satellites

This is yet another glaring example of the innovative spirit of Silicon Valley. The startup has been successfully testing the novel idea on its El Camino Real spacecraft — launched on a Russian Soyuz rocket in July 2019. Momentus will continue to perform simulations on its spacecraft for the next few months to gather enough data to compare it with the results of the ground tests to validate the proper functioning of the new system.

It’s spacecraft, El Camino Real, is a 16-unit CubeSat integrated by Astro Digital — a spacecraft manufacturer and geospatial data analysis company based out of California as well. Momentus has already secured funding of $34 million funding to develop two shuttles, Vigoride and Vigoride Extended, which will maneuver satellites between orbits.

The most prominent application for this is when new satellites are deployed in orbits via rockets. When the former is dropped off in orbits, they can be moved to optimal positions using this technology in a cheap & efficient manner. Momentus originally started off in 2018 as a transportation service for small satellites seeking rides to medium Earth, geostationary or low lunar orbit.

Rarely Seen Gravity Waves Captured Rippling in Earth’s Atmosphere

Posted by in categories: physics, satellites

The atmosphere is fluid. This means it’s subject to fluid dynamics, such as circulation, currents, and, yes, gravity waves. The atmosphere is always in motion, so these phenomena happen all the time; but actually seeing them is another matter.

Well, thanks to weather satellites, now you can take a mighty gawk at atmospheric gravity waves that rippled out over Western Australia last week.

Not to be confused with gravitational waves, which are disturbances in the curvature of spacetime created by massive acceleration, gravity waves, also known as buoyancy waves, are a physical phenomenon where waves are generated in any fluid medium, such as waves at the beach, or ripples in a glass of water.

SpaceX reveals early users of satellite-based high-speed internet

Posted by in categories: Elon Musk, habitats, internet, satellites

(CNN) — SpaceX is on a mission to beam cheap, high-speed internet to consumers all over the globe. And this week the company revealed a few earthly locations that are already linked to the network, including CEO Elon Musk’s house and the cockpits of a few Air Force jets.

It’s part of early testing for the 60 broadband-beaming satellites and two demo devices that SpaceX has already launched into orbit.

Eventually, the company wants to operate thousands of satellites that will circle the planet at about 300 to 700 miles overhead. The project is called Starlink, and if it’s successful it could forever alter the landscape of the telecom industry.

Rocket Report: Would you buy Virgin Galactic stock? Rocket Lab goes lunar

Posted by in categories: materials, satellites

Potential for small science missions … “Small satellites will play a crucial role in science and exploration, as well as providing communications and navigation infrastructure to support returning humans to the Moon,” Rocket Lab head honcho Peter Beck said. “They play a vital role as pathfinders to retire risk and lay down infrastructure for future missions. We think this could be useful for CubeSat science around the Moon or possibly communications relay capability on the cheap.” (submitted by 3ch0 and ADU)

Firefly considering AR1 engine for its Beta rocket. Firefly Aerospace has said it is collaborating with engine-maker Aerojet Rocketdyne to increase the performance of its upcoming Alpha launch vehicle, and the company is also considering Aerojet Rocketdyne’s AR1 engine for a future launch vehicle, SpaceNews reports. In a statement, Firefly CEO Tom Markusic praised the AR1 as an engine well suited for Beta but stopped short of saying the engine’s selection is a done deal.

How far along is AR1 really? … Markusic: “Aerojet Rocketdyne’s AR1 engine, which incorporates the latest advances in propulsion technology, materials science, and manufacturing techniques, is incredibly well-suited to power Beta given its cost-effective, high-performance capabilities.” It is not at all clear to us how close Aerojet is to completing and qualifying the AR1 engine. It also seems like Firefly should get Alpha up and running before it worries too much about the larger Beta rocket. (submitted by Unrulycow)

SpaceX’s Starlink Broadband Service Will Begin in 2020: Report

Posted by in categories: internet, satellites

X, the private spaceflight company known for reusable rockets and a giant, shiny Starship, will begin offering its own satellite internet service in 2020, according to SpaceNews. In fact, the U.S. Air Force is already testing it in planes.

To build the service, SpaceX will have to launch up to eight Falcon 9 rockets filled with the company’s Starlink satellites, SpaceX President and Chief Operating Officer Gwynne Shotwell told SpaceNews and other reporters this week at the 70th International Astronautical Congress in Washington.

“We’ll continue to upgrade the network until mid to late next year,” SpaceNews’ Jeff Foust quoted Shotwell as saying during a media roundtable on Tuesday (Oct. 22). “We’re hoping for 24 launches by the end of the year.”

Pentagon to create ‘AI assistant’ to help tank crews navigate & MAKE DECISIONS in battle

Posted by in categories: drones, military, robotics/AI, satellites

The US Army is working on all-seeing artificial intelligence that would analyze combat data and calculate how to gain supremacy in tank warfare. The project was launched amid growing concerns about using AI in real war.

The brand new program, dubbed Project Quarterback, is aimed at providing tank crews with an AI assistant that would gather all available battlefield data, analyze it and suggest the best way to take out an enemy, Defense One reported. The effort would radically speed up the decision-making in combat, as the AI would collect data from satellites, drones, radars and soldiers’ body cams.

“Simple map displays require 96 hours to synchronize a brigade or division targeting cycle,” Kevin McEnery, the deputy director of the army’s Next Generation Combat Vehicle Cross Functional Team, said at a robotics-themed event last week. He noted that the army’s goal is to bring that down to just “96 seconds, with the assistance of AI.”

Rocket Lab To Begin Missions To The Moon In 2020 With New ‘Photon’ Spacecraft

Posted by in categories: evolution, satellites

Smallsat launcher Rocket Lab has announced its ambition to begin missions to the Moon in the near-future, using a new satellite launch platform it has developed called Photon.

Announced today at the International Astronautical Congress in Washington D.C., Rocket Lab – which current flies its Electron rocket from New Zealand and will begin launching from a U.S. site next year – said Photon would enable small spacecraft to reach lunar orbit or conduct lunar flybys.

Photon is an evolution of the company’s existing kick stage that is used to deploy satellites in orbit, including on the company’s ninth launch last week, which saw them deploy a satellite to their highest altitude yet. It fits into the existing Electron rocket and is essentially its own standalone spacecraft, containing its own instruments, propulsion, fuel tanks, and more.

Rocket Lab—yep, Rocket Lab—has a plan to deliver satellites to the Moon

Posted by in categories: energy, satellites

A Rocket Lab spokesperson told Ars that the new service, launching on an Electron rocket, would be capable of sending up to 30kg into lunar orbit and be available as soon as the fourth quarter of 2020. As for pricing, it was not disclosed. “Pricing is tailored to mission requirements, but we’ll be bringing previously impossible missions within reach at attainable prices,” the spokesperson said.

The “Photon” spacecraft is essentially a small third stage for the Electron rocket that provides in-space maneuvering capability for payloads. It combines propulsion, power, attitude determination and control, and radiation-tolerant avionics. These combined capabilities will allow Rocket Lab to deliver small spacecraft on lunar flyby missions, into a Near Rectilinear Halo Orbit (where NASA intends to build a small space station called the Lunar Gateway), L1/L2 points, or lunar orbit. It will take up to 14 days for the Photon vehicle to deliver a payload to lunar orbit.
