☆ When a cruise liner-size asteroid zips by Earth, two spacecraft may follow it

CNN —When a cruise liner-size asteroid comes within 19,883 miles (32,000 kilometers) of Earth on April 13, 2029, it won’t be alone. The European Space Agency has announced that its new Ramses spacecraft may accompany the asteroid Apophis before and after its safe, albeit rather close, pass of Earth. Astronomers think that an asteroid this large comes within such proximity to Earth only once every 5,000 to 10,000 years. In September 2022, NASA’s DART mission intentionally slammed a spacecraft into Dimorphos, a moonlet asteroid that orbits a larger parent asteroid known as Didymos. “The Ramses mission concept reuses much of the technology, expertise and industrial and science communities developed for the Hera mission,” said Paolo Martino, spacecraft manager for Hera who will also work on the Ramses mission, in a statement.

☆ Rare purple pigment found in Bronze Age pottery

CPA Media Pte Ltd/Alamy Stock PhotoAncient Greeks and the Romans considered Tyrian purple, first developed in the Bronze Age, an elite, royal color. But the recipe for the long-lasting pigment, made using Mediterranean sea snails, disappeared with the fall of the Byzantine Empire. Now, researchers have found the precious pigment within pottery fragments containing 3,600-year-old purple dye from a Bronze Age workshop in Kolonna on the Greek island of Aegina. Life for a vulnerable child in the Stone Age would have been difficult because Neanderthals moved from place to place. Meanwhile, the agency has selected SpaceX to design a vehicle that will drag the space station out of orbit at the end of the decade when it ceases operations and plummets into the ocean.

☆ AstroForge: How this startup plans to make asteroid mining a reality.

Now the California-based startup is attempting to make asteroid mining a reality. That makes AstroForge the only company with a refinery that can turn M-type asteroids into PGMs in space, he adds. Some in the scientific community are skeptical that the private sector will be able to afford asteroid mining. Its all-or-nothing, lower-cost approach may help push asteroid mining closer to reality. “I hope if nothing else,” Gialich says, “we’re known as a space company that went for it.”

☆ Water molecules found on asteroids thought to be ‘completely dry’

CNN —Water molecules have been detected on the surface of asteroids for the first time, proving that these remnants from the formation of our solar system aren’t just dried-up space rocks. Searching for water across the solar systemThe researchers attempted to look for water on two other asteroids using SOFIA, but the detection was too faint. Now, the team is using the James Webb Space Telescope to zero in on different asteroids and search for water signatures. “We really weren’t expecting to find water on these silicate-rich asteroids,” Arredondo said. I want to know if the carbon-rich asteroids have significantly more water than silicate-rich asteroids, or if they have similar amounts.”

☆ NASA reveals a pristine sample collected from a near-Earth asteroid
▼ + stars: | 2023-10-11 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —A pristine asteroid sample that could serve as a time capsule from the early days of our solar system has finally been revealed. “Far exceeding our goal of 60 grams, this is the biggest carbon-rich asteroid sample ever return to Earth. It’s the largest asteroid sample returned to Earth. The burst of gas lifted rocks and dust all the way from 19 inches (50 centimeters) beneath the space rock’s surface. About 70% of the sample will remain pristine in storage so future generations with better technology can learn even more than what’s now possible.
