NASA's Bizarre Plan to Drag an Asteroid into Orbit

By Chris Gayomali

Of all the asteroids relatively close to Earth, a space rock called 1999 AO10 is the most attractive candidate for close-up inspection. But getting to it would be both ridiculously expensive and incredibly dangerous. Sending astronauts there and back would take roughly half a year, and potential rescue missions would be impossible. Astronauts would also be exposing their bodies to untold amounts of radiation once they're outside the Earth's magnetic field.

But there could be another way to study asteroids up close. NASA is reportedly considering a new mission proposed by the Keck Institute for Space Studies that would send a robotic spacecraft to grab a small asteroid, tow it back towards Earth, and then park it in the moon's orbit for us to study as we please. 

New Scientist reports:

The Keck team envisions launching a slow-moving spacecraft, propelled by solar-heated ions, on an Atlas V rocket. The craft would then propel itself out to a target asteroid, probably a small space rock about 7 metres wide. After studying it briefly, the robot would catch the asteroid in a bag measuring about 10 metres by 15 metres and head back towards the moon. Altogether it would take about six to 10 years to deliver the asteroid to lunar orbit.

Asteroids are a keen area of interest for researchers because they contain potentially harvestable valuables like platinum, and perhaps even oxygen, carbon, and hydrogen to fuel our rockets — which would effectively turn asteroids into gas stations for long-distance space travel. In total, the proposed plan would cost $2.6 billion, or just a shade more expensive than the Mars rover team's Curiosity mission.

3500-Year-Old Mummy Discovered in Forgotten Egyptian Tomb

As the site of the ancient city of Thebes, the modern-day Egyptian city of Luxor is filled with archaeological treasures. But until recently, two forgotten tombs—both located in the necropolis of Dra' Abu el-Naga, an important non-royal cemetery—hadn’t been fully explored. Now, National Geographic reports that experts have finally excavated these burial sites and discovered a 3500-year-old mummy, along with ornate funerary goods and colorful murals.

While excavating one of the two tombs, known as Kampp 150, experts found linen-wrapped remains that Egypt's Ministry of Antiquities believes belong to either "a person named Djehuty Mes, whose name was engraved on one of the walls ... [or] the scribe Maati, as his name and the name of his wife Mehi were inscribed on 50 funerary cones found in the tomb's rectangular chamber."

In addition to the mummy, archaeologists discovered wooden statues, masks, earthen pots, a cache of some 450 statuettes, and around 100 funerary cones—conical mud objects, which were often positioned outside a tomb's center, and could have served as identifying markers or as offerings—inside Kampp 150.

The Associated Press reported that the second tomb, known as Kampp 161, is thought to be approximately 3400 years old—about 100 years newer than its neighboring chamber—as its design is characteristic of other such structures dating back to the reigns of Amenhotep II and Thutmose IV.

Inside Kampp 161, archaeologists discovered wooden funerary masks, a decorated coffin, furniture shards, and the mural of a festival or party depicting the tomb's unknown resident and his wife receiving ceremonial offerings.

German scholar Friederike Kampp-Seyfried surveyed and numbered both tombs in the 1990s, which is how they got their names, but she did not fully excavate nor enter either one.

Officials celebrated the rediscovery of the tombs on Saturday, December 9, when they publicly announced the archaeological finds. They hope that discoveries like these will entice foreign travelers to visit Egypt, as political unrest has harmed the country's tourism industry in recent years.

“It’s truly an exceptional day,” Khaled al-Anani, Egypt's antiquities minister, said in a statement. “The 18th dynasty private tombs were already known. But it’s the first time" anyone's ever entered them.

Can You Figure Out This Newly Discovered Optical Illusion?
Kohske Takahashi, i-Perception (2017)
Kohske Takahashi, i-Perception (2017)

Ready to have your mind boggled? Take a look at the image above. What shape are the lines? Do they look like curves, or zigzags?

The image, spotted by Digg, is a new type of optical illusion published in the aptly named journal i-Perception. Discovered by Japanese psychologist Kohske Takahashi, it’s called the “curvature blindness illusion,” because—spoiler—the contrast of the lines against the gray background makes our eye see some of the lines as zigzags when, in fact, they’re all smooth curves.

The illusion relies on a few different factors, according to the three experiments Takahashi conducted. For it to work, the lines have to change contrast just at or after the peak of the curve, reversing the contrast against the background. You’ll notice that the zigzags only appear against the gray section of the background, and even against that gray background, not every line looks angled. The lines that look curvy change contrast midway between the peaks and the valleys of the line, whereas the lines that look like they contain sharp angles change contrast right at the peak and valley. The curve has to be relatively gentle, too.

Go ahead, stare at it for a while.
