In fact, the Space Force’s 45th Weather Squadron predicts 95% odds of “go for launch” weather conditions.

SpaceX announced the Starlink 6–43 launch is targeted for 7:05 p.m. EDT Sunday from Launch Complex 40, with backup opportunities available if needed until 11:03 p.m.

The Falcon 9 rocket will deploy another payload of 23 Starlink broadband satellites into low-Earth orbit, adding to SpaceX’s growing constellation.

April 17, 2021, was a day like any other day on the sun, until a brilliant flash erupted and an enormous cloud of solar material billowed away from our star. Such outbursts from the sun are not unusual, but this one was unusually widespread, hurling high-speed protons and electrons at velocities nearing the speed of light and striking several spacecraft across the inner solar system.

In fact, it was the first time such high-speed protons and electrons—called solar energetic particles (SEPs)—were observed by spacecraft at five different, well-separated locations between the sun and Earth as well as by spacecraft orbiting Mars. And now these diverse perspectives on the solar storm are revealing that different types of potentially dangerous SEPs can be blasted into space by different solar phenomena and in different directions, causing them to become widespread.

“SEPs can harm our technology, such as satellites, and disrupt GPS,” said Nina Dresing of the Department of Physics and Astronomy, University of Turku in Finland. “Also, humans in space or even on airplanes on polar routes can suffer harmful radiation during strong SEP events.”

Liftoff occurred at 5:05 p.m. ET (2205 GMT).

In a study published in The Astrophysical Journal, researchers from the Yunnan Observatories of the Chinese Academy of Sciences depicted a complete physical image of the anomalous heating in the upper atmosphere of the sun (the solar corona and the solar chromosphere).

The enigma of the corona’s anomalous heating stands as one of the eight challenges in modern astronomy. Similarly, the anomalous heating of the chromosphere continues to baffle solar physicists.

Observations gleaned from large telescopes and satellites have revealed potential magnetic activities that could be the cause of this heating. Theoretical research has proposed various heating modes, yet none have been definitively proven to be the cause. As it stands, our understanding of how the sun’s upper atmosphere is heated remains incomplete.

This week now has four flights scheduled, starting with Crew-8, which is sending a new crew to the International Space Station for a six-month tour of duty after successfully launching from Florida. Starlink 6–41 from Cape Canaveral and Transporter 10 from Vandenberg Space Force Base are also on the docket along with the debut of a new small satellite launcher from Japan.

Crew-8 launched three NASA astronauts and one Roscosmos cosmonaut to the Station on March 3, while the Starlink 6–41 flight and Transporter 10 are now due to fly on March 4. The new KAIROS small satellite launcher developed by the Japanese commercial sector is scheduled to fly on March 8.

She continued: “We’ve certainly had more opportunities to target in the last 60 to 90 days,” adding the US is currently looking for “an awful lot” of rocket launchers in the region.

Moore’s comments provide some of the strongest evidence to date that the US military is using AI targeting systems to identify potential strike areas. She noted that even after Google walked away from the project, experimenting has continued with drone or satellite imagery.

Based at Central Command, or Centcom headquarters in Tampa, Florida, Moore revealed that US forces in the Middle East have been testing AI targeting systems using a combination of satellites and other data sources and conducted exercises over the past year with the technology.

Earth’s orbit is so populated that the space industry is now developing technologies to remove space debris caused by satellites from an over-crowded low Earth orbit (LEO).

One untapped orbit above Earth does exist, though. The so-called very low Earth orbit (VLEO) would allow satellites to fly in a less crowded space closer to home and take more detailed pictures of our planet.

It turns out an old dog can learn new tricks. After over 300 flights and 13 years in service, Falcon 9 continues to improve as SpaceX tweaks the design for higher performance.

SpaceX hit a new record on Sunday, flying 24 Starlink v.2 minis aboard a Falcon 9 rocket, surpassing its previous high water mark of 23 satellites. “This mission is carrying one additional Starlink satellite from previous east coast missions thanks in part to performance increases on Falcon 9,” SpaceX wrote on X.

The company did not detail how it was able to squeeze more performance out of Falcon 9. The Starlink v.2 mini debuted at the start of last year, boasting around 4x more capacity than its predecessors. The company has previously been launching 21–23 Starlink satellites per flight.

Measuring the precise quantity of rainfall in a particular area is straightforward when there is equipment specifically designed to accurately capture and relay precipitation data. However, quantifying and identifying the types of precipitation across all locations on Earth presents significant logistical challenges.

Importantly, this information could provide a wealth of data for characterizing and predicting Earth’s water, energy, and biogeochemical cycles. Researchers from China recently deployed a satellite, FengYun 3G (FY-3G), that is successfully collecting Earth precipitation data from space.
