SwRI-led team addresses mystery of heavy elements in galactic cosmic rays
Wednesday, 07 July 2021 04:32
Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving energetic particles, mostly hydrogen ions called protons, the lightest and most abundant elements in the universe. Scientists have long debated how trace amounts of heavy io Satellite galaxies can carry on forming stars when they pass close to their parent galaxies

Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the larger galaxy would remove the gas from it, leaving it shorn of the material it would need to make new stars. However, for the first time, a team led by the researcher at the Instituto de Astrofisica de Canarias (IAC), Arianna di Cintio, ha Kepler telescope glimpses population of free-floating planets
Wednesday, 07 July 2021 04:32
Tantalising evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star. The results include four new discoveries that are consistent with planets of similar masses to Earth, published in Monthly Notices of the Royal Astronomical Society.

The 2020 Atlantic hurricane season was one of the most brutal on record, producing an unprecedented 30 named storms. What's more, a record-tying 10 of those storms were characterized as rapidly intensifying - some throttling up by 100 miles per hour in under two days.
To provide a more consistent watch over Earth's tropical belt where these storms form, NASA has launched a test satellite, Tiangong: astronauts are working on China's new space station - here's what to expect

Three astronauts on China's new space station have just performed the country's first space walk and are busy configuring the module for future crews. Named Tiangong ("heavenly palace"), the station is the Chinese National Space Agency (CNSA)'s signature project to develop China's ambitions for having humans in orbit around Earth for a long amount of time.
In planning since the late 1990s, OneWeb names winners of 2021 Innovation Challenge
Wednesday, 07 July 2021 02:50
SAN FRANCISCO – IRT Saint Exupéry, Mbryonics, Morpheus Space, Oledcomm and R3-IoT were the winners of OneWeb’s 2021 Innovation Challenge, a campaign to designed to “rethink satellite connectivity” and establish new partnerships, according to London-based OneWeb.
OneWeb announced the winners July 1 during an online event tracking the launch of 36 broadband communications satellites on an Arianespace Soyuz rocket from Russia’s Vostochny Cosmodrome.

WASHINGTON — Earth imaging company Satellogic announced July 6 it will go public through a merger with a special purpose acquisition company (SPAC), raising the funding it needs to build out a constellation of 300 spacecraft.
Satellogic said it will merge with CF Acquisition Corp.
China conducts third orbital launch inside four days

The heart of a lunar sensor

The heart of the Exospheric Mass Spectrometer (EMS) is visible in this image of the key sensor that will study the abundance of lunar water and water ice for upcoming missions to the Moon.
This spectrometer is being delivered to NASA today as part of the PITMS instrument for its launch to the Moon later this year.
EMS is based on an ‘ion trap’, an ingenious detector device that allows researchers to identify and quantify sample atoms and molecules in a gas and allows to establish a corresponding mass spectrum. Scientists at The Open University and RAL Space are developing EMS
Significant solar flare erupts from sun
Tuesday, 06 July 2021 10:39
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.
JWST passes launch review

WASHINGTON — The James Webb Space Telescope is one step closer to launch after a review of its Ariane launch vehicle, while NASA continues a separate review of the name of the spacecraft itself.
Raytheon to develop Long Range Standoff nuclear missiles in $2B contract
Tuesday, 06 July 2021 08:11
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 Space Force selects first 50 transfers from Army, Navy, Marine Corps
Tuesday, 06 July 2021 08:11
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. Britain to spend $4.8M developing inter-missile communication system
Tuesday, 06 July 2021 08:11
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 NASA rocket, satellite tag-team to view the giant electric current in the sky
Tuesday, 06 July 2021 08:11
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.
