A lunar probe launched by the Chinese space agency recently brought back the first fresh samples of rock and debris from the moon in more than 40 years. Now an international team of scientists—including an expert from Washington University in St. Louis—has determined the age of these moon rocks at close to 1.97 billion years old.

"It is the perfect sample to close a 2-billion-year gap," said Brad Jolliff, the Scott Rudolph Professor of Earth and Planetary Sciences in Arts & Sciences and director of the university's McDonnell Center for the Space Sciences. Jolliff is a U.S.-based co-author of an analysis of the new moon rocks led by the Chinese Academy of Geological Sciences, published Oct. 7 in the journal Science.

The age determination is among the first scientific results reported from the successful Chang'e-5 mission, which was designed to collect and return to Earth rocks from some of the youngest volcanic surfaces on the moon.

Western Australia's homegrown spacecraft, Binar-1, has been shot into the vacuum of space- deployed into Low Earth Orbit from the International Space Station (ISS), five weeks after blasting off from Cape Canaveral in Florida.

Director of Curtin's Space Science and Technology Centre (SSTC), John Curtin Distinguished Professor Phil Bland, joined SSTC staff and students yesterday to watch a live feed as Binar-1 was placed into the tiny airlock of the Japanese Experiment Module Kibo on the ISS and sent into space.

Professor Bland explained WA's first homegrown spacecraft is now on a journey to make first contact before testing critical systems, collecting data and taking photographs from 400 kilometers above Earth.

"The launch of WA's first homegrown spacecraft on the Space-X rocket was exciting, but this moment and the coming few days are the really crucial points for our Binar Space Program and the team of staff and students who designed and built Binar-1 from scratch," Professor Bland said.

"We can't wait to hear Binar-1's 'first words' from space—that will be the time when we will be able to declare the success of our first space-mission and put us firmly on the path to proving that our technology can deliver.

On Saturn's giant moon Titan, liquid methane and other hydrocarbons rain down, carving rivers, lakes and seas in a landscape of frozen water. The complex chemistry on this icy world could be analogous to the period when life first emerged on Earth, or it might yield an entirely new type of life.

NASA's Lucy spacecraft will launch in October 2021 on a 12-year journey to Jupiter's Trojan asteroids. The Lucy mission will include three Earth gravity assists and visits to eight asteroids.

Called "Trojans" after characters from Greek mythology, most of Lucy's target asteroids are left over from the formation of the solar system. These Trojans circle the sun in two swarms: one that precedes and one that follows Jupiter in its orbit of the sun. Lucy will be the first spacecraft to visit the Trojans, and the first to examine so many independent solar system targets, each in its own orbit of the sun.

Studying Jupiter's Trojan asteroids up close would help scientists hone their theories on how our solar system's planets formed 4.5 billion years ago and why they ended up in their current configuration. "It's almost like we're traveling back in time," said aerospace engineer Jacob Englander, who helped design Lucy's trajectory while working at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

First conceived seven years ago as a mission to two asteroids, Lucy expanded to epic proportions thanks to creative engineering and impeccable timing.
