Israel has secured $8.7 billion US aid package to support ongoing military campaigns — Defense Ministry

Israel has secured an $8.7 billion aid package from the United States to support its ongoing military efforts and to maintain a qualitative military edge in the region, the Defense Ministry announces in a statement.

The package includes $3.5 billion for essential wartime procurement, which has already been received and earmarked for critical military purchases, and $5.2 billion designated for air defense systems including the Iron Dome anti-missile system, David’s Sling, and an advanced laser system.

Psyche mission launches as NASA’s first trip to a metal world

(October 13, 2023)

To accomplish the rest of the mission, the van-size spacecraft will rely on its new solar electric propulsion system, powered by Hall-effect thrusters, Oh said. The thrusters will utilize the spacecraft’s large solar arrays and “use electricity to ionize xenon gas and accelerate those charged ions through an electric field to very, very high speeds,” Oh said. (…)

Also along for the ride is the Deep Space Optical Communications technology demonstration, or DSOC. Occurring during the first two years of the journey to Psyche, it will be NASA’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser.

ILLUMA-T

NASA wants to update its existing radio communications system on the International Space Station (ISS) with optical communication technology. Optical communication systems, which use laser beams to transmit information through space, promise the ability to transmit data between a spacecraft and Earth at a much higher rate than radio-frequency systems. Our researchers are designing ILLUMA-T*, a laser terminal that will provide an optical communications link from the ISS to NASA‘s Laser Communications Relay Demonstration satellite, which, in turn, will use optical communications to relay the data from the ISS link to a ground terminal at a rate 10 to 100 times faster than current radio frequency communications systems.

NASA’s Laser Communications Relay: A Year of Experimentation

(Jun 28, 2023)

The Laser Communications Relay Demonstration (LCRD) uses infrared light, or invisible lasers, to transmit and receive signals rather than radio wave systems conventionally used on spacecraft. Infrared light’s tight wavelengths allow space missions to pack significantly more data – 10 to 100 times more – into a single transmission. More data means more discoveries.

Now, at the halfway point in its experimentation phase, LCRD has shown laser communications’ significant advantages over traditional radio wave systems.

Elon Musk now controls over a quarter of all active satellites as SpaceX prepares to launch 1,000th Starlink

SpaceX CEO Elon Musk now controls a quarter of all active satellites orbiting Earth after launching more than a dozen Starlink missions over the last two years.

A Falcon 9 rocket will deliver the latest batch of 60 Starlink satellites into orbit from Nasa’s Kennedy Space Center in Florida this week, weather permitting, taking the total number of Starlinks in orbit to over 1,000.

Astronomers detect gravitational waves created by massive neutron star collision

Neutron stars are the smallest in the universe, the remnants of supernovae. Their diameters are comparable to the size of a city like Chicago or Atlanta, but they are incredibly dense, with masses bigger than that of our sun. So think of the sun, compressed into a major city — and then think of two of them violently crashing into each other.

Missing Link: Zweifel trotz Nobelpreis – Streit über Graviationswellen-Messungen

LIGO und Virgo sind die ersten Experimente ihrer Art. Die Kollaboration umfasst mehrere tausend Physiker und damit fast jeden, der heute als Experte zu Graviationswellen durchgeht. Aus diesem Grund kann die LIGO/Virgo-Kollaboration es sich leisten, Kritik einfach zu ignorieren, auf ihre eigenen Analyseverfahren zu vertrauen und die Welt im Unklaren darüber zu lassen, genau wie sie eigentlich was analysiert.

Führungskampf in der EU-Rüstungsindustrie

Heftige Auseinandersetzungen um die Führung bei milliardenschweren Rüstungsprojekten begleiten den heutigen deutsch-französischen Ministerrat in Toulouse. Streitobjekte sind der Bau eines gemeinsamen Kampfpanzers (Main Ground Combat System, MGCS) und eines gemeinsamen Kampfjets (Future Combat Air System, FCAS), die beide als künftige Standardwaffen für die Streitkräfte der EU-Mitgliedstaaten konzipiert sind. Allein der Markt für das MGCS wird auf bis zu 100 Milliarden Euro geschätzt.

Navy to Equip Destroyers With High Powered Lasers

(14.04.2019)

News.usni.org reports that the Navy intends to install a High Energy Laser and Integrated Optical-dazzler with Surveillance (HELIOS) weapon system aboard a West Coast Arleigh Burke-class Flight IIA destroyer by 2021. The new laser is intended to operate at 60 kilowatts, three times more powerful than the laser weapons system the Navy tested aboard the USS Ponce five years ago. The laser system is mainly intended to target small attack boats and unmanned aerial vehicles.

The HELIOS system is to be developed by Lockheed Martin.

Air Force Research Laboratory completes successful shoot down of air-launched missiles

During the series of tests at the High Energy Laser System Test Facility at White Sands Missile Range, the Demonstrator Laser Weapon System (DLWS) (Figure 1), acting as a ground-based test surrogate for the SHiELD system, was able to engage and shoot down several air launched missiles in flight. The demonstration is an important step of the SHiELD system development, by validating laser effectiveness against the target missiles. The final SHiELD system, however, will be much smaller and lighter, as well as ruggedized for an airborne environment.

The US Air Force successfully tested a laser system to shoot down missiles

SHiELD also not the only laser technology that’s in testing by the US military — the US Army tested a system mounted on an AH-64 Apache attack helicopter last summer, and the US Navy is working with Lockheed Martin on its own systems to install on warships.
