NASA taps AI to identify “fresh craters” on Mars

NASA’s Jet Propulsion Laboratory uses an AI tool on a supercomputer cluster to identify potential craters on the Red Planet.

On July 15, 1965, the Mariner 4 spacecraft snapped a series of photographs of Mars during its flyby of the Red Planet. These were the first “close-up” images taken of another planet from outer space, according to NASA. One of these first grainy photographs depicted a massive crater nearly 100 miles in diameter. Now, NASA’s Jet Propulsion Laboratory (JPL) is tapping artificial intelligence (AI) to help with its cosmic cartography efforts, using these technologies to identify “fresh craters” on Mars.

For more than 14 years, the Mars Reconnaissance Orbiter (MRO) has transmitted detailed images of Mars back to researchers on Earth. Scientists have used orbiter data to spot more than 1,000 new Martian craters.

Importance of moving activities outdoors and ensuring proper ventilation indoors stressed, as experts urge science community to clarify definitions — ScienceDaily

Scientists affiliated with leading research institutions across the U.S. state in a letter published Monday in the journal Science that researchers across disciplines must converge to deliver clear public health guidance about how SARS-CoV-2 is spread in the air.

The researchers write in the open letter that the scientific community must clarify the terminology used related to aerosols and droplets, and employ a more modern size threshold, rather than the existing one based on 1930s-era work. Authors include experts from the University of California San Diego, University of Maryland, Virginia Tech, and others.

Public health officials should make a clear distinction between droplets ejected by coughing or sneezing — which have inspired the social distancing mantra of six feet of separation between people — and aerosols that can carry the virus for much greater distances. Viruses in aerosols smaller than 100 microns can remain airborne in a confined space for

PSA: First Free Year of Apple TV+ Subscriptions Ending, Expect Charges on October 31

With the launch of the iPhone 11 lineup and the introduction of the Apple TV+ subscription service in the fall of 2019, Apple gave those who purchased an iPhone, iPad, Mac, or Apple TV a free year of Apple TV+.


For those who signed up for Apple TV+ right when it was available on November 1, 2019, those free year-long Apple TV+ accounts are expiring at the end of October. A year is a long time to remember to cancel a subscription, so we wanted to warn MacRumors readers not interested in keeping Apple TV+ that charges are imminent. The first subscribers will be charged for Apple TV+ on October 31, 2020.

For Apple TV+, Apple did not allow subscriptions to be canceled right after signup because doing so would end the subscription right away, so there are many potentially active Apple TV+ subscriptions out there. Here’s how to cancel.

SpaceX, L3Harris win Space Development Agency contracts to build missile-warning satellites

SDA Director Derek Tournear said SpaceX “came in with an extremely credible proposal” that leverages the Starlink assembly line

WASHINGTON — The Space Development Agency awarded SpaceX a $149 million contract and L3Harris a $193.5 million contract to each build four satellites to detect and track ballistic and hypersonic missiles.

The contracts announced Oct. 5 are for the first eight satellites of a potentially much larger Space Development Agency constellation of sensor satellites known as Tracking Layer Tranche 0. This is SpaceX’s first military contract to produce satellites. 

Both companies have to each deliver four satellites by September 2022, Space Development Agency Director Derek Tournear told SpaceNews.

Each satellite will have a “wide field of view” overhead persistent infrared (OPIR) sensor capable of detecting and tracking advanced missile threats from low Earth orbit. Each satellite also will have an optical crosslink so it can pass data to relay satellites.

the saga contines. CDC saying once again virus is airborne

If only they had told the white house sooner.

The Centers for Disease Control and Prevention acknowledged Monday that people can sometimes be infected with the coronavirus through airborne transmission, especially in enclosed spaces with inadequate ventilation.

The long-awaited update to the agency Web page explaining how the virus spreads represents an official acknowledgment of growing evidence that under certain conditions, people farther than six feet apart can become infected by tiny droplets and particles that float in the air for minutes and hours, and that they play a role in the pandemic.

“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than six feet away,” the updated Web page states. “These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising. the updated Web page states.”

“Under these

North San Jose tech center is bought by California investor

Two modestly size office buildings that sit on a north San Jose lot that’s big enough to be redeveloped have been bought by a Southern California investor.

In a rare occurrence for Silicon Valley office buildings, the sellers sold the property for less than what they paid for it, Santa Clara County public records show.

An affiliate of JW Capital Inc., which is headed by San Diego-based investor John Wang, bought the two north San Jose buildings in a cash deal, according to property documents filed on Oct. 2.

The two buildings are located at 1110 and 1120 Ringwood Ct. in San Jose and together they total about 79,000 square feet, according to a brochure prepared by CBRE, a commercial real estate firm that has been working to find tenants for the office buildings.

JW Capital paid $10.6 million for the two buildings, county documents show. The buildings make up

The Future of Omnichannel Starts Today: 4 Omnichannel Strategies that Will Help You Stay Ahead of the Curve in 2021

This year hasn’t gone as anyone expected (biggest understatement right there). COVID-19 threw a wrench in the year 2020, and every industry has felt its effects. Customer Experience is no exception. In fact, the CX industry has changed rapidly this year. Digital consumerism went through the roof and remote work became the norm.

The companies that have slid through 2020 with the fewest bruises are the ones that already had strong omnichannel systems in place. They built goals with the future of omnichannel in mind, and now they’re ahead of the curve. Consumers have gone completely digital-first–buying everything from groceries to furniture online–and a lot of companies are swimming hard to keep up. Though we don’t know what next year holds, it’s clear that omnichannel solutions are here to stay.

Here are four strategies to follow to keep up with the future of omnichannel.

Sharpness of star-forming image matches expected resolution of Webb Space Telescope — ScienceDaily

NASA’s James Webb Space Telescope is still more than a year from launching, but the Gemini South telescope in Chile has provided astronomers a glimpse of what the orbiting observatory should deliver.

Using a wide-field adaptive optics camera that corrects for distortion from Earth’s atmosphere, Rice University’s Patrick Hartigan and Andrea Isella and Dublin City University’s Turlough Downes used the 8.1-meter telescope to capture near-infrared images of the Carina Nebula with the same resolution that’s expected of the Webb Telescope.

Hartigan, Isella and Downes describe their work in a study published online this week in Astrophysical Journal Letters. Their images, gathered over 10 hours in January 2018 at the international Gemini Observatory, a program of the National Science Foundation’s NOIRLab, show part of a molecular cloud about 7,500 light years from Earth. All stars, including Earth’s sun, are thought to form within molecular clouds.

“The results are stunning,” Hartigan

  • Even if a coronavirus vaccine is approved soon, it will likely be years until it can be distributed around the world, according to cargo airline and logistics executives.
  • Challenging storage and shipping requirements, combined with reduced cargo availability and higher demand, are likely to delay distribution, according to a new Wall Street Journal report.
  • Although cargo airlines are trying to prepare, a host of unknowns — including where the vaccine will be made, how many doses are needed, and how it will need to be stored — means there’s only so much that can be organized in advance.
