XRISM satellite launches to study the universe in different colors of X-rays

Posted by in categories: cosmology, satellites

On Sept. 6, a new satellite left Earth; its mission is to tell us about the motions of hot plasma flows in the universe.

Launched from Tanegashima Space Center in Japan, the X-Ray Imaging and Spectroscopy Mission (XRISM) satellite will detect X-ray wavelengths with unprecedented precision to peer into the hearts of galaxy clusters, reveal the workings of and supernovae, as well as to tell us about the elemental makeup of the universe.

XRISM, pronounced “crism,” is a collaborative mission between the Japan Aerospace Exploration Agency (JAXA) and NASA, with participation by the European Space Agency.

Japan firm unveils satellite with goal to approach space debris in world 1st

Posted by in category: satellites

The satellite, dubbed ADRAS-J, was unveiled by Tokyo-based venture Astroscale Japan Inc., which is developing technology to remove space debris including the remains of satellites and rockets that have reached the end of their operational lives.

The satellite is 80 centimeters in length and width, 1.2 meters high and weighs about 150 kilograms. It is scheduled to be launched by a commercial rocket from New Zealand by the end of this fiscal year. The satellite aims to come within a few to several… More.


TOKYO — A demonstration satellite scheduled to be launched within fiscal 2023 that aims to approach space debris, apparently in the first attempt of its kind in the world, was shown to the press on Sept. 7.

Did Elon Musk prevent a Russia-Ukraine nuclear war?

Posted by in categories: Elon Musk, existential risks, internet, military, satellites, sustainability

New details of Musk’s involvement in the Ukraine-Russia war revealed in his biography.

Elon Musk holds many titles. He is the CEO of Tesla SpaceX and owns the social media company X, which was recently rebranded from Twitter. Going by an excerpt of his biography, published in the Washington Post.

According to the excerpt from Walter Isaacson’s book, Musk disabled his company Starlink’s satellite communication networks, which were being used by the Ukrainian military to attack the Russian naval fleet in Sevastopol, Crimea, sneakily. The Ukrainian army was using Starlink as a guide to target Russian ships and attack them with six small… More.

Meteosat weather satellite captures Earth in stunning detail

Posted by in category: satellites

Today’s Image of the Day from European Space Agency features the first image of the full Earth disc from the Meteosat Third Generation Imager.

This is the first of a new generation of satellites that is expected to revolutionize weather forecasting by enabling more precise monitoring of our changing atmosphere, land and oceans.

Simonetta Cheli, ESA’s Director of Earth Observation Programmes, said that the image is a great example of what European cooperation in space can achieve.

SpaceX Just 30 Launches Away From 2023 Goal As Musk Lauds Remarkable Milestone

Posted by in categories: Elon Musk, internet, satellites

Elon Musk’s rocket manufacturing company SpaceX has completed 60 launches this year, much to the CEO’s excitement.

What Happened: SpaceX’s Falcon 9 rocket launched 22 Starlink satellites to low-Earth orbit from Florida on Thursday at about 10:21 p.m. ET, marking the company’s 60th launch this year.

“Congrats to the SpaceX team on launch 60 of 2023!” Musk wrote.

SpaceX Falcon 9 Launches Starlink 6–13 Mission

Posted by in categories: climatology, internet, policy, satellites

For the first time in my timezone, SpaceX completed 9 launches in a month. Previously, if you were based in Europe, you saw 9 launches in a month a few months ago. At 9 launches/month that is a current rate of 108 launches/year, making SpaceX’s goal of 100 launches this year a possibility.

They had a lot of trouble getting this flight off today as a recent hurricane is still affecting the weather some. They got around this by having a 5 and a half hour launch window so they just waited a few hours until the weather was clear for several minutes and they launched!

A particular way of creating quantum entanglement may improve accuracy of advanced quantum sensors

Posted by in categories: particle physics, quantum physics, satellites

Metrological institutions around the world administer our time using atomic clocks based on the natural oscillations of atoms. These clocks, pivotal for applications like satellite navigation or data transfer, have recently been improved by using ever higher oscillation frequencies in optical atomic clocks.

Now, scientists at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences led by Christian Roos show how a particular way of creating entanglement can be used to further improve the accuracy of measurements integral to an optical atomic clock’s function. Their results have been published in the journal Nature.

Observations of are always subject to a certain statistical uncertainty. “This is due to the nature of the quantum world,” explains Johannes Franke from Christian Roos’ team. “Entanglement can help us reduce these errors.”

SpaceX Reportedly Achieved Profitability In The First Quarter Of 2023

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

SpaceX, led by Elon Musk, has reportedly achievedability in the first quarter of 2023, marking a significant milestone for the privately owned rocket company. According to the Wall Street Journal (WSJ), SpaceX reported a of $55 million on $1.5 billion in revenue for the January-to-March period. This success comes after two years of narrowing losses, with the company managing to cut its 2022 losses to $559 million from the previous year’s $968 million while doubling its revenue to $4.6 billion.

The positive financial results reflect SpaceX’s growing revenue, driven in part by its Starlink internet satellite service and the development of its ambitious Starship rocket. The company’s surging revenue has enabled it to make progress towardability while pursuing its ambitious goals in space exploration and satellite communication.

The WSJ report also sheds light on SpaceX’s significant expenses, with the company recording total expenses of $5.2 billion in 2022, up from $3.3 billion in the previous year. Despite these costs, SpaceX’sability in the first quarter signals the potential for its ongoing success as it continues to innovate and expand its operations in the space industry.

Satellite built as low-cost way to reduce space junk reenters atmosphere years early

Posted by in categories: mathematics, satellites

SBUDNIC, built by an academically diverse team of students, was confirmed to have successfully reentered Earth’s atmosphere in August, demonstrating a practical, low-cost method to cut down on space debris.

When it comes to space satellites, getting the math wrong can be catastrophic for an object in orbit, potentially leading to its abrupt or fiery demise. In this case, however, the fiery end was cause for celebration.

About five years ahead of schedule, a small cube satellite designed and built by Brown University students to demonstrate a practical, low-cost method to cut down on reentered Earth’s atmosphere sometime on Tuesday, Aug. 8 or immediately after—burning up high above Turkey after 445 days in orbit, according to its last tracked location from U.S. Space Command.
