The team recreated a turbulent magnetic reconnection, suggested to be a trigger of solar flares.

On January 10, NASA’s Solar Dynamics Observatory recorded a massive X-class solar flare. The blast hurled debris into space, and radiation from the flare triggered radio blackouts across the South Pacific. The solar outburst was the third X-class — the most powerful — flare in less than a week.

These intense bursts of radiation from the release of magnetic energy associated with sunspots can be dangerous — in February 2022, SpaceX lost 40 of its newly launched Starlink communications satellites due to a geomagnetic storm triggered by a solar flare.

SpaceX signed a new agreement with the U.S. National Science Foundation (NSF) to prevent Starlink satellites from interfering with astronomy.

SpaceX has long been criticized by astronomers for the brightness of its Starlink satellites. Elon Musk, the CEO of SpaceX, said in 2019 that SpaceX would ensure that Starlink has no material effect on discoveries in astronomy. “We care a great deal about science,” he said in a tweet.

Exactly, potentially helping billions of economically disadvantaged people is the greater good. That said, we’ll make sure Starlink has no material effect on discoveries in astronomy. We care a great deal about science.

A group of hackers was able to take control of a decommissioned satellite and use it to stream a hacking conference’s talks and hacker movies.

On Saturday, at the DEF CON hacking conference in Las Vegas, Karl Koscher, one of the members of a hacking enthusiasts group called Shadytel, explained how he and his friends were able to legally stream from a satellite in geostationary orbit—35,786 km or 22,236 miles from the surface of the planet.

The satellite had been decommissioned and was about to be sent to the so-called “graveyard orbit,” a far-away orbit where satellites go to die.

WALLOPS ISLAND, Va. — A rocket launch set for Monday, January 23 in Virginia will be visible to much of the east coast of the United States, according to NASA.

The 59-foot-tall Electron rocket from Rocket Lab USA is set to take off from NASA’s Wallops Flight Facility along the southeastern coast of Virginia sometime between 6 and 8 p.m.

The mission, named “Virginia is for Launch Lovers,” will deploy radio frequency monitoring satellites for Virginia based geospatial analytics company HawkEye 360. NASA said the mission will help foster a growing low-Earth space economy.

The world’s second-most powerful rocket—though it’s largest partially renewable rocket—yesterday blasted-off on a secret mission for the US Space Force amid spectacular views. Only the fifth flight of the company’s heavy-life Falcon Heavy rocket (though the second inside a few months), the event took place in twilight Sunday, with a satellite being successfully sent into geosynchronous Earth orbit (meaning it will orbit at the same speed as Earth rotates). Two side-boosters then returned to land in tandem on launch pads.

They were the 163th and 164th successful landings of an orbital-class rocket, according to SpaceX.

The mission, called USSF-67, took a communications satellite into orbit for the US military.

UltraAir will enable the exchange of large amounts of data using laser beams in a network of ground stations and satellites in geostationary orbit at 36,000 km above the Earth.

Aerospace corporation Airbus and Dutch high-tech industrial supplier VDL Group will jointly develop and manufacture a laser communication terminal for aircraft, known as UltraAir, according to a press release by the first company published on Tuesday.

The concept is based on a project led by Airbus and the Netherlands Organisation for Applied Scientific Research (TNO). The two companies will now prepare a demonstration of a prototype and a first flight test in 2024.

The satellite had an expected two-year-service life, but it blew past that mark. “For 21 of its years in orbit, the ERBS actively investigated how the Earth absorbed and radiated energy from the Sun, and made measurements of stratospheric ozone, water vapor, nitrogen dioxide, and aerosols,” NASA said.

Spacefaring machines that come back to Earth are subject to an intense reentry process. NASA expected most of ERBS to burn up, “but for some components to survive the reentry.” The return trajectory over a body of water means anything that wasn’t toast likely fell harmlessly into the sea.

The satellite’s uneventful fall back to its home planet is a bit of good news at a time when orbital space is increasingly crowded with junk, debris and defunct satellites. ERBS went out in a blaze of glory after its distinguished service to science.

A modified Boeing 747 aircraft, nicknamed Cosmic Girl, will launch a rocket from under its wing around midnight local time.

S SpaceX works towards the first orbital launch of its fully reusable Starship rocket, Sir Richard Branson’s Virgin Orbit is looking to perform the first-ever orbital launch from British soil.

If all goes to plan, the Virgin Orbit launch will kickstart an exciting year for the British space industry.

“The 5,400-pound satellite will reenter the atmosphere at approximately 6:40 pm EST on Sunday, January 8,” with no risk to humans.

National Aeronautics and Space Administration’s (NASA) defunct satellite is poised to hit the ground on Sunday.

“The Department of Defense predicted that the 5,400-pound satellite will reenter the atmosphere at approximately 6:40 p.m. EST on Sunday, January 8, with an uncertainty of +/- 17 hours,” read the statement.

A team from Nagoya University in Japan has observed, for the first time, the energy transferring from resonant electrons to whistler-mode waves in space. Their findings offer direct evidence of previously theorized efficient growth, as predicted by the non-linear growth theory of waves. This should improve our understanding of not only space plasma physics but also space weather, a phenomenon that affects satellites.

When people imagine , they often envision it as a perfect vacuum. In fact, this impression is wrong because the vacuum is filled with charged particles. In the depths of space, the density of charged particles becomes so low that they rarely collide with each other.

Instead of collisions, the forces related to the electric and magnetic fields filling space, control the motion of charged particles. This lack of collisions occurs throughout space, except for very near to celestial objects, such as stars, moons, or planets. In these cases, the charged particles are no longer traveling through the vacuum of space but instead through a medium where they can strike other particles.
