The Hottest Catalog of the Year: Comprehensive List of Slow-building Solar Flares

Posted by in categories: energy, satellites

Although solar flares have been classified based on the amount of energy they emit at their peak, there has not been significant study into differentiating flares since slow-building flares were first discovered in the 1980s. Scientists have now shown that there is a significant amount of slower-type flares worthy of further investigation.

Solar flares occur when magnetic energy builds up in the Sun’s atmosphere and is released as electromagnetic radiation. Lasting anywhere from a few minutes to a few hours, flares usually reach temperatures around 10 million degrees Kelvin. Because of their intense electromagnetic energy, solar flares can cause disruptions in radio communications, Earth-orbiting satellites and even result in blackouts.

The width-to-decay ratio of a flare is the time it takes to reach maximum intensity to the time it takes to dissipate its energy.

Cabot Institute for the Environment

The short lifespan of conventional batteries means they either cannot be used or have significant drawbacks in situations where it is not feasible to charge or replace them. For example, pacemakers, satellites, high-altitude drones or even spacecraft are low-power electrical devices where long life of the energy source is needed.

SpaceX to deorbit 100 older Starlink satellites

Posted by in categories: internet, satellites

TITUSVILLE, Fla. — SpaceX plans to remove from orbit about 100 of its older Starlink satellites because of a design flaw that could cause them to fail.

In a statement Feb. 12, SpaceX said it would perform controlled descents of about 100 “early-version 1” Starlink satellites out of concerns that the spacecraft could fail in orbit and no longer be maneuver.

“These satellites are currently maneuverable and serving users effectively, but the Starlink team identified a common issue in this small population of satellites that could increase the probability of failure in the future,” SpaceX stated. The company did not elaborate on that issue or identify the specific satellites affected.

SpaceX aims to let astronauts avoid a radio blackout during re-entry

Posted by in categories: internet, satellites

When spacecraft re-enter Earth’s atmosphere, friction heats them up and creates a plasma sheath that stops communications – but SpaceX thinks its Starlink satellites could solve the problem.

SpaceX launches billion-dollar environmental research satellite for NASA

Posted by in categories: biological, climatology, education, satellites, sustainability

SpaceX launched an environmental research satellite for NASA early Thursday, a nearly $1 billion spacecraft that survived multiple cancellation threats and is now poised to shed new light on climate change and the complex interplay of heat-trapping carbon, aerosols and sea life on global scales.

The Plankton, Aerosol, Cloud, ocean Ecosystem mission — PACE — “will dramatically advance our understanding of the relationship between aerosols and clouds, and the global energy balance,” said Karen St. Germain, director of NASA’s Earth sciences division. “This is one of the biggest sources of uncertainty in our ability to model the climate.”
