Scores of internet-providing satellites will soon streak across Canada's skies, but at what cost?
Tuesday, 21 September 2021 19:03
The night sky is going to get much busier thanks to thousands of new internet satellites set to launch over the next few years—and researchers say it's going to affect Canada more than most places on Earth.
Researchers from the University of Toronto, the University of Regina and the University of British Columbia found that most light pollution is expected to happen near 50 degrees latitude north and south due to the orbits of the new satellites.

Could low-altitude reconnection power Jupiter's polar aurorae?
Tuesday, 21 September 2021 13:30
Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions exceed those generated on our planet. Of particular interest are patches of emission that originate from even closer to the poles than the main aurorae, a feature that appears far stronger at Jupiter than at Earth or Saturn.

Artemis rover to land near Nobile region of Lunar south pole
Tuesday, 21 September 2021 12:14
In 2023, NASA's Volatiles Investigating Polar Exploration Rover (VIPER) will land near the western edge of the Nobile Crater at the Moon's South Pole to map and explore the region's surface and subsurface for water and other resources. Part of Artemis, VIPER will launch on a SpaceX Falcon-Heavy rocket for delivery to the Moon by Astrobotic's Griffin lander under NASA's Commercial Lunar Payload
Discovery about meteorites informs atmospheric entry threat assessment
Tuesday, 21 September 2021 12:14
Researchers at the University of Illinois Urbana-Champaign watched fragments of two meteors as they ramped up the heat from room temperature to the temperature it reaches as it enters Earth's atmosphere and made a significant discovery. The vaporized iron sulfide leaves behind voids, making the material more porous. This information will help when predicting the weight of a meteor, its likelihoo Small stature limits Mars' ability to hold water, study finds

For a planet to be habitable, it must be able to hold significant amounts of liquid water.
When considering a planet's potential habitability, scientists mostly look at a planet's atmosphere and its distance from its host star. But novel research out of Washington University in St. Louis suggests size matters, too.
According to the new study, published Monday in the journal PNAS, NASA plans to send lunar rover to Nobile region of moon's South Pole

NASA's ice-hunting VIPER lunar rover, scheduled to arrive on the moon in 2023, would land near the Nobile Crater on the lunar South Pole, the space agency announced Monday.
The crater offers a relatively safe area to hunt for water ice, which is considered crucial for long-term Artemis missions to explore the moon and eventually Mars, NASA officials said. The ice could provide a water s NASA offers new website to look at Mars rover images

Fans of NASA's Mars rover Perseverance can now see the robotic explorer and its activity in a 3D depiction of the Red Planet terrain via a new website.
The site, Explore with Perseverance, is updated when the rover makes a significant move. NASA has uploaded seven locations, starting with the Octavia E. Butler Landing Site at which the spacecraft landed Feb. 18.
Software develope Lunar crater named after Arctic Explorer Matthew Henson
Tuesday, 21 September 2021 12:14
The International Astronomical Union has named a crater at the Moon's south pole after the Arctic explorer Matthew Henson, a Black man who in 1909 was one of the first people to stand at the very top of the world. The proposal to name the crater after Henson came from Jordan Bretzfelder, an Exploration Science summer intern with the Lunar and Planetary Institute, in Houston, TX, which is a membe Mars habitability limited by its small size, isotope study suggests

Water is essential for life on Earth and other planets, and scientists have found ample evidence of water in Mars' early history. But Mars has no liquid water on its surface today. New research from Washington University in St. Louis suggests a fundamental reason: Mars may be just too small to hold onto large amounts of water.
