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.
The heart of a lunar sensor
Image:
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
Satellogic to public through SPAC deal
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

OneWeb names winners of 2021 Innovation Challenge
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.
Methane in the plumes of Saturn's moon Enceladus: Possible signs of life?
An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences and Lettres University.
Giant water plumes erupting from Enceladus have long fascinated scientists and the public alike, inspiring research and speculatio What does it take to do a spacewalk
On June 25, astronauts Shane Kimbrough and Thomas Pesquet successfully completed an almost seven-hour EVA (extravehicular activity, or spacewalk) to install solar panels on the International Space Station. What does it take to don a spacesuit and venture out on such a technical and dangerous mission? Surprisingly, one of the main criteria (besides the years of astronaut training) is body size. Skyroot Aerospace completes Series A funding
Skyroot Aerospace, India's leading private space launch company, is set to take the global stage with help from its recent $11 million Series A capital raise. The funding will be used to acquire new talent and complete the development of its Vikram-1 launch vehicle.
The company aims to reach orbit, with 90 percent less development cost than its competitors, as early as next year. This disr Mars helicopter begins to scout for Perseverance rover with longest flight
NASA's Mars helicopter Ingenuity has begun to scout missions for the Perseverance rover, completing its ninth and most challenging flight yet.
NASA announced the "most challenging flight yet" was a success Monday via Twitter.
Flight nine included a speed record for the aircraft at roughly 11 mph, which NASA called "a high-speed flight across unfriendly terrain, which will take us Ancient diamonds show Earth was primed for life's explosion at least 2.7 billion years ago
A unique study of ancient diamonds has shown that the basic chemical composition of the Earth's atmosphere which makes it suitable for life's explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today's mantle, which in turn indicates that there has been no fundamenta
