Significant solar flare erupts from sun
The sun emitted a significant solar flare peaking at 10:29 a.m. EDT on July 3, 2021. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however—when intense enough—they can disturb the atmosphere in the layer where GPS and communications signals travel.
To see how such space weather may affect Earth, please visit NOAA's Space Weather Prediction Center at spaceweather.gov, the U.S. government's official source for space weather forecasts, watches, warnings and alerts.
This flare is classified as an X1.5-class flare.
X-class denotes the most intense flares, while the number provides more information about its strength.
Earth's cryosphere shrinking with every passing year
The global cryosphere-all of the areas with frozen water on Earth-shrank by about 87,000 square kilometers (about 33,000 square miles), a area about the size of Lake Superior, per year on average, between 1979 and 2016 as a result of climate change, according to a new study. This research is the first to make a global estimate of the surface area of the Earth covered by sea ice, snow cover and f Tactically Responsive Launch-2 payload launched into orbit
When the U.S. Space Force's Tactically Responsive Launch-2 (TacRL-2) mission launched from Vandenberg Space Force Base on June 13, it carried a payload designed and built in record time by Lawrence Livermore National Laboratory (LLNL).
LLNL provided a three-mirror reflective telescope and sensor for the payload, which they designed, integrated, tested and delivered within four months of th Visualizing quieter supersonic flight
NASA's X-59 Quiet SuperSonic Technology X-plane is designed to fly faster than the speed of sound without producing sonic booms - those loud, startling noises which can be disruptive to humans and animals.
Currently, commercial aircraft aren't allowed to fly faster than the speed of sound over land because of the objectionable sonic booms they cause for those on the ground.
This expe Report that China building new ICBM silos 'concerning': US
The United States expressed concern on Thursday over a report that China is building more than 100 new silos for intercontinental ballistic missiles.
The Washington Post, citing a study of commercial satellite images by a California-based group, reported on Thursday that the silos were being built in a desert near the northwestern city of Yumen.
The James Martin Center for Nonproliferati NASA rocket, satellite tag-team to view the giant electric current in the sky
Some 50 miles up, where Earth's atmosphere blends into space, the air itself hums with an electric current. Scientists call it the atmospheric dynamo, an Earth-sized electric generator. It's taken hundreds of years for scientists to lay the groundwork to understand it, but the principles that keep it running are only just now being revealed in detail.
Following up on its predecessor's 2013 Britain to spend $4.8M developing inter-missile communication system
Britain invested $4.8 million for smarter missile systems - allowing munitions to communicate and react quickly to changing threats - the British Ministry of Defense said on Thursday.
The contract was awarded to the Defense Science Technology Laboratory for the Co-operative Strike Weapons Technology Demonstrator, which the British government is charging with improving current systems Space Force selects first 50 transfers from Army, Navy, Marine Corps
Fifty active-duty Army, Navy and Marine Corps personnel have been chosen to transfer to the U.S. Space Force and will join the branch in July, the Space Force said on Wednesday.
The group will test integration efforts to bring additional personnel into the new military branch, founded in 2019 with a mandate to deter aggression and protect the interests of the United States in space. Raytheon to develop Long Range Standoff nuclear missiles in $2B contract
The Pentagon this week awarded Raytheon a contract worth up to $2 billion to develop a new nuclear cruise missile.
The contract, announced Thursday, calls for development of the new missiles through 2027, when a first flight could occur and a decision about production may be made.
The series of air-launched, Long-Range Standoff weapons would replace the Air Launched Cruise or AGM European Robotic Arm ready for space

The European Robotic Arm (ERA) will be launched to the International Space Station together with the Russian Multipurpose Laboratory Module, called ‘Nauka’. ERA is the first robot able to ‘walk’ around the Russian segment of the Space Station. It has the ability to anchor itself to the Station and move back and forward by itself, hand-over-hand between fixed base-points. This 11-metre intelligent space robot will serve as main manipulator on the Russian part of the Space Station, assisting the astronauts during spacewalks. The robot arm can help install, deploy and replace elements in outer space
ERA is 100% made-in-Europe.
