Mystery Road's Madeleine Madden wants to 'create change'

  Mystery Road's Madeleine Madden wants to 'create change' By her own admission, Madeleine Madden is having a “full-on” year. The talented young actress is everywhere in 2018. Currently, she’s on our screens in Foxtel’s lavish remake of Picnic At Hanging Rock and the ABC’s outback drama Mystery Road.Later, she'll appear in the ABC/Netflix co-production Pine Gap and Netflix's supernatural crime series Tidelands.

A decades-old lunar mystery has now been solved thanks to the recovery of once lost data tapes and a massive amount of sleuthing. Researchers from Texas Tech University used recovered tapes from the 1970s Apollo missions to understand why the Moon ’s surface appeared to have warmed.

After eight years spent recovering lost Moon data from the Apollo missions, scientists report in a new study they’ve solved a decades-old mystery of The missing tapes and the weekly performance logs gave the researchers enough new information to tease out a likely cause for the mysterious heating.

The results confirm that inexplicable changes in the moon’s temperatures recorded in the 1970s were not the result of some strange inner heat source, but rather the by-product on astronauts stomping around and stirring up moon dust.

In a study published in April in the Journal of Geophysical Research: Planets, researchers from Texas Tech University used recovered tapes from the 1970s Apollo missions to understand why the moon’s surface appeared to have warmed. These records were taken on the Apollo 15 mission, the fourth mission to land men on the moon in 1971, The Smithsonian reported.

Can You Solve This Ice Cream Cone Riddle?

  Can You Solve This Ice Cream Cone Riddle? How much is an ice cream cone worth? In this visual riddle by Budapest-based artist Gergely Dudás (who posts comics on Dudolf.com), the answer requires a little math.The riddle asks you to determine how much an ice cream cone, a scoop of white-colored ice cream (let’s call it vanilla), and a scoop of pink-colored ice cream (let’s call it strawberry) are worth, according to the logic of the puzzle.Stare at the equations for a while, then scroll down for the answer.

A decades-old lunar mystery has now been solved thanks to the recovery of once lost data tapes and a massive amount of sleuthing. Researchers from Texas Tech University used recovered tapes from the 1970s Apollo missions to understand why the Moon ’s surface appeared to have warmed.

The primary purpose of this trip was to observe the moon’s surface through a variety of experiments. This included drilling probes into the moon that sent information back to Earth. Records of the moon’s temperature were taken from 1971-1977 but data from 1974-1977 were lost, Sciencealert reported.

The team was only able to recover less than 10 percent of all the lost tapes, and the information they could recover was poorly degraded. However, they did their best to restore the tapes and were able to fill in some of the gaps with the help of some hardcore science skills. Now, eight years after the tapes were originally discovered, the team have concluded that human activity was the reason for the temperature increases measured on the moon.

The biggest indication that humans were the cause of the temperature increases on the moon was that the warming was stronger on the surface and faded in measurements taken deeper in the moon. This suggests that the source was not from inside the moon.

It appeared that the astronauts and their rovers stirred up the moon's loose outer surface dirt, exposing darker surface dirt—also known as regolith—that would have otherwise been hidden. Just as you learned to avoid dark shirts in the summer as dark colours absorb heat, the same is true for the moon’s surface. The now-darker dirt absorbed more of the sun’s heat, initially increasing the moon’s temperature.

In addition, photos acquired from the Lunar Reconnaissance Orbiter Camera show that there are dark surface paths on the moon where astronauts have traversed, Sciencealert reported.

“We suggest that, as a result of the astronauts' activities, solar heat intake by the regolith increased slightly on average, and that resulted in the observed warming,” the researchers wrote.
