NASA Invites Media to Launch of Mars 2020 Perseverance Rover – Stockhouse

Published

on


WASHINGTON, June 3, 2020 /PRNewswire/ — Media accreditation is open for the launch of NASA’s Mars 2020 Perseverance rover, designed to better understand the geology of Mars and seek signs of ancient life on the Red Planet.

The mission will use the robotic scientist, which weighs just under 2,300 pounds and is the size of a small car, to collect and store a set of rock and soil samples that could be returned to Earth by future Mars Sample Return missions. It also will test new technology to benefit future robotic and human exploration of Mars.

Perseverance will launch on a United Launch Alliance Atlas V 541 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The launch of Perseverance is scheduled for 9:15 a.m. EDTJuly 17 and is managed by NASA’s Launch Services Program. Live coverage of the launch will air on NASA TV and the agency’s website.

Due to the ongoing coronavirus (COVID-19) pandemic, NASA will be credentialing a limited number of media to cover the Mars 2020 launch from the agency’s Kennedy Space Center in Florida. Due to COVID-19 safety restrictions at Kennedy and quarantine requirements, international media who would be coming from overseas will not be able to register for this launch. International media already based in the U.S. may apply.

Media accreditation deadlines are as follows:

  • U.S. media must apply by 4 p.m. EDT Sunday, June 28
  • International media already in the U.S. must apply by 4 p.m. EDT Tuesday, June 9

All media accreditation requests should be submitted online at:

https://media.ksc.nasa.gov

NASA is proactively monitoring the coronavirus (COVID-19) situation as it evolves. The agency will continue to follow guidance from the Centers for Disease Control and Prevention and the agency’s chief health and medical officer and communicate any updates that may impact mission planning or media access, as they become available.

For questions about accreditation, please email ksc-media-accreditat@mail.nasa.gov. For other questions, contact Kennedy’s newsroom at 321-867-2468.

Reporters with special logistics requests for Kennedy, such as space for satellite trucks, trailers, tents, electrical connections, or work spaces, must contact Tiffany Fairley at tiffany.l.fairley@nasa.gov by Sunday, June 28.

The Perseverance rover was built at NASA’s Jet Propulsion Laboratory in Southern California.

The Mars 2020 mission is part of NASA’s larger Moon to Mars exploration approach that includes missions to the Moon as a way to prepare for human exploration of the Red Planet. Charged with landing the first woman and the next man on the Moon by 2024, NASA will establish a sustained human presence on and around the Moon by 2028 through NASA’s Artemis program.

Grizzly bears in the dark as they try to share living space with humans: study – Medicine Hat News

Published

By Bob Weber, The Canadian Press on July 7, 2020.

A grizzly bear roams an exhibit at the Woodland Park Zoo, closed for nearly three months because of the coronavirus outbreak, Tuesday, May 26, 2020, in Seattle. Grizzly bears are doing their best to get along with people, but it still isn’t enough. Newly published research assessing more than 40 years of data concludes that without large wilderness areas to replenish their numbers, the bears would disappear from landscapes they share with humans.

EDMONTON – Grizzly bears are doing their best to get along with people, but it still isn’t enough.

Newly published research concludes that without large wilderness areas to replenish their numbers, grizzlies would disappear from landscapes they share with humans.

“The persistence of bears near people, when we see them along highways or near towns, they’re really propped up by the fact they exist near some sort of secure wilderness,” said Clayton Lamb, a University of Alberta biologist and lead author of a paper published in the Proceedings of the National Academy of Sciences.

Researchers found bears in populated areas in Alberta and British Columbia have even changed how they hunt in an attempt to share living space with humans.

“The bears are doing what they can,” Lamb said. “The difference might have to be made up by us.”

The study set out to examine an emerging phenomenon in wildlife conservation – large carnivores re-establishing themselves on mixed landscapes including cities, highways, rural communities and patchworks of natural habitat.

It digested 41 years worth of mortality, movement and demography among 2,669 grizzlies over nearly 400,000 square kilometres of British Columbia.

It found mortality has increased steeply with the amount of human impact measured through an index that includes human population, land use, infrastructure, coastlines, roads, railroads and navigable rivers.

Deaths have outnumbered births and the difference is being made up through emigration of young grizzlies from nearby wilderness. For every point the index increases, a local bear population must increase the number of individuals it draws by about two per cent.

“Grizzly bear range is quite tied to the distance from some secure piece of wilderness,” said Lamb.

That’s despite the grizzlies’ efforts to adapt to humans. The study found young, newly arrived bears gradually learned ways to avoid contact, such as hunting and gathering at night.

Adolescent bears in areas dominated by humans have increased their nocturnal time by up to three per cent annually, which has led to corresponding increases in survival. The cost, however, is steep.

The scientists found it takes 14 years for a grizzly to learn how to co-exist with humans. For every bear that makes it, 29 don’t.

“A lot of those bears would have been born on a mountaintop 10 kilometres away and lived with mom in an avalanche chute and lived a normal bear life,” Lamb said.

“Then they find a home near town and get lured in by an apple tree. The gauntlet they have to run is very difficult.”

The study shows that high mortality has impacts far from where the deaths take place. Bears dying in mixed-used areas draws more grizzlies from the wilderness to take their place.

“Conflicts with people have rippling effects on (bear) populations far removed,” Lamb said.

Highway overpasses are one good way to reduce deaths, he suggests. But humans living with bears have to get better at removing attractants such as roadkill or fruit trees to end the bears’ constant, often fatal, migration from the wilderness.

“We’re not quite there,” said Lamb. “The system relies quite heavily on adjacent wilderness.”

Odd pink snow in the Alps is pretty, but it might also be a red flag – CNET

Pink snow, also called “watermelon snow,” has appeared at the Presena glacier in northern Italy, according to researcher Biagio Di Mauro of the Institute of Polar Sciences at Italy’s National Research Council. While it’s not uncommon for the Italian alps to be “pretty in pink” in spring and summer, scientists become cautious when the phenomenon, which is caused by algae, starts happening more frequently. 

Di Mauro told CNN that 2020’s lack of snowfall and higher temperatures have nurtured the algae’s growth. More algae could lead to ice melting faster.

When Di Mauro tweeted clarification for an article from The Guardian, he said the algae was probably Chlamydomonas nivalis, a snow algae. He also said the algae’s relationship with climate change hasn’t been proven yet. 

Di Mauro tweeted photos of the pink snow on Monday.

Across the ocean, in late May, Antarctica reported green snow, caused by microscopic algae. Though microscopic, the green blooms could be spotted by satellites. The color might also have connections with the impact of warming climates, researchers said.
