NASA's OSIRIS-REx spacecraft reaches down to grab rocks from the surface of Bennu asteroid - The

A passenger bus-sized spacecraft, designed and built by Lockheed Martin, lowered itself to the surface of the asteroid Bennu, some 200 million miles from Earth. It touched the rocky surface with a robotic arm that emitted a charge of nitrogen to stir up and capture pebbles and dust on the surface .

Shortly after NASA got word from the spacecraft that its arm had touched down safely, Dante Lauretta, a planetary scientist at the University of Arizona and the principal investigator of the mission, said he felt "transcendental, I mean I can't believe we actually pulled this off. ... History was made tonight."

Iron Man Noida| Alien or Iron Man?

A bizarre and fear-inducing spotting was made in Greater Noida’s Dankaur town. According to the residents they had seen an ‘alien’ around.

It was said that the so-called extra-terrestrial object was seen floating in the air until it landed in a canal situated near the Bhatta Parsaul village. The people had gathered around to see what it was and were terrified because they thought that it was an alien.

Later, the Noida Police came to the scene and clarified that it was actually a balloon shaped like the Marvel superhero ‘Iron Man’ that was the root of all the chaos that ensued.

Early Maps of Geologic Strata, an Oliver Sacks Documentary and a New Science Podcast - Scientific

Strata: William Smith’s Geological Maps
edited by the Oxford University Museum of Natural History
University of Chicago Press, 2020 ($65)

Strata are the ribboned horizontal layers of minerals and sediment that underlie the topography of all the landmasses on the earth and have been revealed by erosion over hundreds of millions of years. Although the practice of mapping geologic layers had begun in the mid-17th century, the science of how strata formed was still nascent.

CVL Local CD Reviews for Oct. 21 | The Buzz | dailyprogress.com

Ace Frehley, the founding Kiss guitarist and amateur extraterrestrial, offers up another helping of classic rock hits he loved while growing up, complete with some high-profile assists.

The most fun track is a cover of the Beatles' "I'm Down," where Ace and guitarist John 5 go off on wild solo runs with all the energy and exuberance of a teenage garage band.

Lita Ford provides vocals on "Jumpin' Jack Flash," Cheap Trick's Robin Zander does likewise on Humble Pie's "30 Days in the Hole," and one of Frehley's Kiss successors on lead guitar, Bruce Kulick, puts his own unique spin on Hendrix's "Manic Depression." There's also a cover of the Kiss staple "She."

Mars mania — a two-part series - Delaware Gazette

We are now just past an excellent close approach, called by astronomers an “opposition,” of the planet Mars. Mars will not be as bright in the sky or as big in a telescope until 2035.

Such was the case in 1895, when, night after clear night, Percival Lowell trained his enormous refracting telescope in Flagstaff, Arizona, at mysterious Mars.

Most significantly, he saw thin lines crisscrossing the planet. He concluded that the lines were canals designed and built by a race of intelligent Martians to transport the water from the Martian polar caps to the rest of Mars extraordinarily arid surface.

The Hunt for Earthlike Exoplanets – Now. Powered by Northrop Grumman

Moreover, the planet must orbit in its parent star’s habitable zone, hot enough that any oceans don’t freeze solid, but not so hot that they boil away.

What makes the search so challenging, Lockwood noted, is that current instruments, even the most powerful, don’t allow astronomers to actually see extrasolar planets. Instead, astronomers must currently suss out planets by observing indirect effects, like the planet’s bulk blocking part of its parent star, slightly dimming the star’s light — the technique used by the TESS mission.

Election 2020: What GOP, Democrats should do if they win Senate

Joe Biden seems poised to win the presidency and take office with Democratic majorities in the House and Senate. Republicans are quietly resigning themselves to sinking in a sea of Trump fatigue, yet they hope to keep the Senate as a check on Democratic excess. The former vice president has promised both an era of national healing and "the most progressive administration since FDR." No one is betting the farm against the latter.

Visions of a continentwide social laboratory run by the Sanders-Warren wing are reason enough to fight for the Senate. But a successful fight might also buy the GOP time to repair some self-inflicted wounds.
