SpaceX acquires parachute company for $2.2M, because it turns out space-rated parachutes are very hard

Posted by in category: satellites

SpaceX is known for its vertical integration, but one component it’s been outsourcing is parachutes — until earlier this month, when the company quietly acquired parachute vendor Pioneer Aerospace after its parent company went bankrupt. The Information first reported the news.

This is the second known acquisition for SpaceX, which acquired small satellite startup Swarm in 2021 for a $524 million mostly-stock deal. Pioneer is coming much more cheaply: SpaceX has snapped it up for just $2.2 million, according to a bankruptcy filing by Pioneer’s parent company in Florida.

WATCH: TESS, NASA’s new exoplanet hunter, launches on a SpaceX Falcon 9 rocket

A pair of planet-hunting satellites — NASA’s TESS and the European Space Agency’s CHEOPS— teamed up for the observations.

None of the planets in perfect synchrony are within the star’s so-called habitable zone, which means little if any likelihood of life, at least as we know it.

First 360-degree cameras in space capture incredible images of Earth

Posted by in categories: electronics, satellites

The first 360-degree cameras sent to space have captured incredible, high-definition images of Earth like never before seen.

Chinese tech company Insta360 recently unveiled the breathtaking photos of the blue planet against the deep darkness of space which were taken by its two cameras attached to satellites orbiting Earth.

Insta360 launched the satellites with the 360-degree action cameras attached about 310 miles into space on Jan. 16 after beginning the project in July 2021.

SpaceX launches “limitless” ‘zero fuel’ engine into space

Posted by in categories: quantum physics, satellites

IVO chief executive Richard Mansell said his company performed 100 hours of vacuum chamber testing before the launch, during which the quantum drive produced a small amount of thrust.

“Deploying Quantum Drive into orbit in a Rogue satellite on SpaceX Transporter 9 is a milestone for the future of space propulsion,” Mansell said.

“Quantum Drive’s capability allows Rogue to produce new satellite vehicles with unlimited Delta V.”

A nanosatellite and a hot air balloon for emergency broadband anywhere

Posted by in categories: computing, internet, satellites, security

It is estimated that 95% of the planet’s population has access to broadband internet, via cable or a mobile network. However, there are still some places and situations in which staying connected can be very difficult. Quick responses are necessary in emergency situations, such as after an earthquake or during a conflict. So too are reliable telecommunications networks that are not susceptible to outages and damage to infrastructure, networks can be used to share data that is vital for people’s well-being.

A recent article, published in the journal Aerospace, proposes the use of nanosatellites to provide comprehensive and stable coverage in areas that are hard to reach using long-range communications. It is based on the bachelor’s and master’s degree final projects of Universitat Oberta de Catalunya (UOC) graduate David N. Barraca Ibort.

The paper is co-authored by Raúl Parada, a researcher at the Telecommunications Technological Center of Catalonia (CTTC/CERCA) and a course instructor with the UOC’s Faculty of Computer Science, Multimedia and Telecommunications; Carlos Monzo, a researcher and member of the same faculty; and Víctor Monzón, a researcher at the Interdisciplinary Center for Security Reliability and Trust at the University of Luxembourg.

Revolutionizing Satellite Security: NASA’s Groundbreaking Project To Integrate AI, Blockchain, & Nanosatellites

Posted by in categories: blockchains, economics, internet, robotics/AI, satellites, security

As part of pioneering the security of satellite communication in space, NASA is funding a groundbreaking project at the University of Miami’s Frost Institute for Data Science and Computing (IDSC) which will enable augmenting traditional large satellites with nanosatellites or constellations of nanosatellites.

These nanosatellites are designed to accomplish diverse goals, ranging from communication and weather prediction to Earth science research and observational data gathering. Technical innovation is a hallmark of NASA, a global leader in the development of novel technologies that enable US space missions and translate to a wide variety of applications from Space and Earth science to consumer goods and to national and homeland security.

With advances in satellite technology and reduced cost of deployment and operation, nanosatellites also come with significant challenges for the protection of their communication networks. Specifically, small satellites are owned and operated by a wide variety of public and private sector organizations, expanding the attack surface for cyber exploitation. The scenario is similar to Wi-Fi network vulnerabilities. These systems provide an opportunity for adversaries to threaten national security as well as raise economic concerns for satellite companies, operators, and users.

The Importance of the Earth’s Atmosphere in Creating the Large storms that Affect Satellite Communications

Posted by in categories: particle physics, satellites

A study from an international team led by researchers from Nagoya University in Japan and the University of New Hampshire in the United States has revealed the importance of the Earth’s upper atmosphere in determining how large geomagnetic storms develop. Their findings reveal the previously underestimated importance of the Earth’s atmosphere. Understanding the factors that cause geomagnetic storms is important because they can have a direct impact on the Earth’s magnetic field such as causing unwanted currents in the power grid and disrupting radio signals and GPS. This research may help predict the storms that will have the greatest consequences.

Scientists have long known that geomagnetic storms are associated with the activities of the Sun. Hot charged particles make up the Sun’s outer layer, the one visible to us. These particles flow out of the Sun creating the ‘solar wind’, and interact with objects in space, such as the Earth. When the particles reach the magnetic field surrounding our planet, known as the magnetosphere, they interact with it. The interactions between the charged particles and magnetic fields lead to space weather, the conditions in space that can affect the Earth and technological systems such as satellites.

An important part of the magnetosphere is the magnetotail. The magnetotail is the part of the magnetosphere that extends away from the Sun, in the direction of the solar wind flow. Inside the magnetotail is the plasma sheet region, which is full of charged particles (plasma). The plasma sheet is important because it is the source region for the particles that get into the inner magnetosphere, creating the current that causes geomagnetic storms.
