BepiColombo Meets Mercury for the First Time on October 1

BepiColombo made a quick visit to Venus in August and is on to its next rendezvous. On October 1st it’ll perform a flyby of Mercury, the spacecraft’s eventual destination. This visit is just a little flirtation—one of six—ahead of its eventual orbital link-up with Mercury in late 2025.

The quick visit will yield some scientific results, though, and they’ll be just a taste of what’s ahead in BepiColumbo’s one-year mission to Mercury.

Japan’s Mission to Phobos Will Also Bring a Sample Home by 2029

Japan’s space agency (JAXA) is gearing up for its Martian Moons eXploration (MMX) mission, with plans to have a sample from Mars’ moon Phobos return to Earth by 2029. Mission scientists say they hope to find clues to the origins of Mars two moons, as well as Mars itself, and possibly even traces of past life.

“We think that the Martian moon, Phobos, is loaded with material lifted from Mars during meteorite impacts,” the MMX team said on Twitter. “By collecting this Phobos sample, MMX will help investigate traces of Martian life and the new era of Martian habitability exploration in the 2020s will begin.”

The First Images and Videos from the Double Venus Flyby

Two spacecraft made historic flybys of Venus last week, and both sent back sci-fi-type views of the mysterious, cloud-shrouded planet.

The Solar Orbiter and BepiColombo spacecraft both used Venus for gravity assists within 33 hours of each other, capturing unique imagery and data during their encounters.

Satellite Images Can Help Predict When Underwater Volcanos are About to Erupt

Predicting volcanic eruptions is notoriously tricky. In large part this is because volcanos are unique, each with their own quirks and personalities: the lessons learned from studying one volcano may not apply directly to another. Luckily, researchers are getting better at finding warning signs that they can apply broadly. Some of the most well-known are heightened seismic activity, rising temperatures, expanding magma pools, and the release of gases. New research using satellite imagery now offers a new warning sign for underwater volcanos: a change in the color of the ocean.

Lunar Rovers! Transform and Roll Out!

A number of missions are destined for the Moon before this decade is over. In addition to the Artemis Program, the European Space Agency (ESA), the China National Space Agency (CNSA), Roscosmos, and other space agencies have some ambitious plans of their own. These include sending robotic missions to characterize the local environment, scout out resources, and pave the way for permanent human outposts.

The Japanese Aerospace Exploration Agency (JAXA) also some very interesting lunar missions in mind. In addition to partnering with NASA on the Artemis Program and helping to create the Lunar Gateway, JAXA has the radical idea to send a transforming rover to the Moon. The data this rover collects will be used to inform the design of a pressurized rover that will allow for a sustained human presence on the Moon.

JAXA Using Water Bottle Technology for Sample-Return Missions From the ISS

The International Space Station (ISS) is not only the largest and most sophisticated orbiting research facility ever built, it is arguably the most important research facility we have. With its cutting-edge facilities and microgravity environment, the ISS is able to conduct lucrative experiments that are leading to advances in astrobiology, astronomy, medicine, biology, space weather and meteorology, and materials science.

Unfortunately, the cost of transporting experiments to and from the ISS is rather expensive and something only a handful of space agencies are currently able to do. To address this, the Japanese Aerospace Exploration Agency (JAXA) and Tiger Corporation partnered in 2018 to create a new type of container that would cut the cost of returning samples to Earth. With the success of their initial design, JAXA and Tiger are looking to create a reusable version that will allow for regular sample returns from the ISS.

Animation Shows how Saturn’s Rings Move at Different Speeds

Saturn’s rings are one of the most recognized and revered celestial objects known to the human race. From a distance, they look like a disk of layered crystal or multicolored disks within disks that wrap around Saturn’s hazy umber face. When viewed up close, we see that these rings are actually particles of water ice (from microns to icebergs), as well as silicates, carbon dioxide, and ammonia.

We would also noticed that the rings have some interesting orbital mechanics. In fact, each ring has a different orbit that is the result of its proximity to Saturn (i.e., the closer they are, the faster they orbit). To illustrate what this complex system look like, NASA Fellow Dr. James O’Donoghue created a stunning animation that shows how each of Saturn’s major ring segments (A-Ring to F-Ring) orbit together around the planet.

OSIRIS-REx Did One Last Close Flyby of Asteroid Bennu. It’s Almost Time to Come Home

After more than two years in orbit around asteroid Bennu, NASA’s OSIRIS-REx spacecraft is ready to come home. It’s bringing with it a pristine sample of space rocks that geologists here on Earth are eager to study up close. The sample will arrive in September 2023, but we won’t have to wait nearly that long for new data from OSIRIS-REx. Last week, the probe carried out one final flyby of Bennu, in an effort to photograph the sample collection site. The photographs are being downlinked now, and should be here by midweek.

If you’ve been following the OSIRIS-REx mission, you probably already know why scientists are keen to see these photographs, but if you haven’t, hold on to your hats – it’s a wild story.

What Could We Learn From a Mission to Phobos?

According to new research that appeared in the scientific journal Nature Geoscience, the larger of Mars’ two moons (Phobos) has an orbit that takes it through a stream of charged particles (ions) that flow from the Red Planet’s atmosphere. This process has been taking place for billions of years as the planet slowly lost its atmosphere, effectively establishing a record of Martian climate change on Phobos’ surface.

This research has provided yet another incentive for landing a mission on Phobos, something that has never been done successfully. In essence, this mission could gather sample data that would allow scientists to study this record more closely. In the process, they would be able to learn a great deal more about how Mars went from being a warmer world with liquid water to the extremely arid and cold environment it is today.

Japan to Launch ‘Wooden Satellite’ in 2023

What a proposed wooden satellite could (and could not) accomplish.

A strange satellite proposal made at the end of 2020 by a Japanese company had many space pundits scratching their heads into 2021.

The proposal came out of Kyoto University in partnership with Sumitomo Forestry in Japan, though most of the information on the project comes from a BBC post quoting Japanese Aerospace Exploration Agency (JAXA) astronaut and Kyoto University professor Takao Doi, who flew aboard the U.S. space shuttle on missions STS-87 and STS-123 to the International Space Station. STS-123 delivered and installed JAXA’s Kib? module in 2008.
