(Astronauts pounded a “drive tube” into the lunar ground to pull a core of material, weighing about 800 grams.) Astronauts on Apollo-era moon-landing missions brought many rock samples down to Earth; these were vacuum-sealed and have never been exposed to our atmosphere.
The cockpit voice recorder and flight data recorder from Ethiopian Flight 302 arrived in Paris on Thursday, where investigators will examine the data that could reveal what brought down the Boeing 737 MAX 8 jet.
That may sound like a lot of airplanes—but American Airlines alone operates almost 1,000 passenger jets. And unlike what happens when there is, say, a freak snowstorm or computer outage, most airlines should have time to reach out to customers scheduled to fly on the Boeing 737 MAX in the coming days and weeks.
The solution, then, is twofold: Boeing started by warning airlines that the MAX’s angle of attack sensors had malfunctioned before, that such a failure could lead the MCAS to push the plane’s nose down, and that pilots could safely defuse the problem by cutting off the trim system and working the plane manually.

This is one of several lines of evidence, Bretherton said, “that would favor the range of predictions that’s 3 to 5 degrees, not the 2- to 3-degree range.” Schneider’s new simulation with Kaul and Pressel improved on Bretherton’s earlier work primarily by connecting what happens in a small patch of stratocumulus cloud to a simple model of the rest of Earth’s climate.
The Trail of Opportunity and More Eye Candy From Space The long and Martian road: In August 2010, the Opportunity rover looked back and took a photo of its tracks in the Red Planet’s sand.
It even produced a study called “Trailer truck trajectory optimization: the transportation of components for the Airbus A380.” That’s just to build the thing—actually flying it required rejiggering airport infrastructure .
If you’re able to divert your eyes from the big show in the upper right, take a look at the object in the center of the image: That blue cloud is LHA 120-N 180B, likely an active star-forming region.
“Once that decline begins, it will never end.” Penguin Random House But Empty Planet is not a book about statistics so much as it is about what’s driving the choices people are making during the fastest period of change in human history.
How to Stream All the Bowls For a complete day of baby-animal cuteness and Super Bowl insanity, you'd normally need a cable subscription that includes CBS for the Super Bowl, Animal Planet for the Puppy Bowl, and the Hallmark Channel for the Kitten Bowl.
In 2004, Meehl and Claudia Tebaldi predicted that climate change would lead to worse, more frequent heat waves; turns out they were right. “The cold air kind of pinches and stretches into two border vortices,” says Judah Cohen, a climatologist with Atmospheric and Environmental Research.
How to Stream All The Bowls For a complete day of baby animal cuteness and Super Bowl insanity, you'd normally need a cable subscription that includes CBS for the Super Bowl, Animal Planet for the Puppy Bowl, and the Hallmark Channel for the Kitten Bowl.
NASA’s Mars Reconnaissance Orbiter and its HiRISE camera capture the surface of the planet in unprecedented detail, and that includes dunes like the ones seen here. Mars, Jupiter, Saturn, stars, and galaxies aren’t even the half of it.
Collins Aerospace's M-Flex Duet is a self-service snack bar that can fold out of the way for landing and takeoff. Rockwell Collins Industry supplier Collins Aerospace wants to reclaim the eight feet or more of open space in front of the emergency exit doors on widebody, twin-aisle jets.
Helping with that transition is an especially important challenge for the World Bank because most of the population growth in the coming decades will be in developing countries. I like to think that Korea’s embrace of sustainability was in part facilitated by World Bank supported environmental education programs in the 1990s.
10 Years Later, Retrace the 'Miracle on the Hudson' Flight The Airbus jet was just 2,800 feet up and nowhere near its cruising speed when the engines failed, giving pilots Chesley “Sully” Sullenberger and Jeffrey Skiles just a few minutes to find a safe path to the ground.
A Strange Kind of Data Tracks the Weather—and Pirate Ships Spire A group of apes is called a shrewdness; a group of ferrets is called a business; a group of small satellites is called a constellation.
In the past year, separate teams of researchers have dug up, pulverized and laser-blasted pieces of rock that may contain life dating to 3.7, 3.95 and maybe even 4.28 billion years ago.
Robocars, Elon, and More This Year in the Future of Cars Our review of 2018 includes usual suspects like Elon Musk, along with mathematicians willing to chat airplane peeing, clock-watching RAF pilots, and a whole lot of transportation planners.
Space Photos of the Week: Juno Spies Jupiter's Mesmerizing Clouds Take a second with this one. This is Io. This infrared image taken by the Juno spacecraft from some 290,000 miles away, reveals what looks like a bad case of space chicken pox, but those bright spots, all of them, are actually volcanoes.
Night Shyamalan realized the need to break form years ago when he made Unbreakable. (One reason: people in real life using their great power with great irresponsibility.) Shyamalan followed Unbreakable with 2016’s Split, featuring a bald James McAvoy with 20-odd personalities that semi-cohere into a frightening super-crazy.
“I am still very concerned.” He later cited another launch of 31 objects, of which only 18 had been identified three and a half days in.“We put our plan in front of all the regulators and in front of the Combined Space Operations Center,” Blake says, referring to the relevant part of the Air Force.
At the south pole, the thawing of water and carbon dioxide ices create odd metallic-looking patterns, while at the north pole, an intricate array of polygons appears when the planet transitions from winter to spring.Enjoying being a temporary Martian?
“Over the last 20 years of doing this, we’ve gotten better at thinking about the economic costs,” says John Furlow, a development and aid expert at Columbia University’s International Research Institute for Climate and Society and an author of NCA4.
