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.
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.
A fireball hurtled across the sky on December 5th – the sample return capsule from the Hayabusa2 asteroid mission by JAXA (Japan Aerospace Exploration Agency). The capsule landed in Woomera, a remote location in the Australian Outback. Earlier this month, the capsule’s sample containers revealed fine grain topsoil from asteroid 162173 Ryugu. A second sample container has since been opened that contains chunks up to an entire centimeter in size.
On December 5th, 2020, the Japanese Aerospace Exploration Agency’s (JAXA) Hayabusa 2 mission sent a sample capsule home containing debris from the near-Earth asteroid (NEA) 162173 Ryugu. This was the culmination of the probe’s first six years in space, which launched in Dec. 2014 and rendezvoused with Ryugu in June 2018. While the probe sets its sights on its new targets, scientists will be busy analyzing the Ryugu sample.
One thing they noticed immediately after opening the shell on Monday (Dec. 21st) was the black sandy dust that lined the capsule’s outer shell. According to a statement issued by JAXA, the black sand is material taken from the surface of Ryugu. Considering what’s inside sample chamber A, it appears that the amount of material obtained by Hayabusa 2 is more substantial than previously thought.
A remarkable microbe named Deinococcus radiodurans (the name comes from the Greek deinos meaning terrible, kokkos meaning grain or berry, radius meaning radiation, and durare meaning surviving or withstanding) has survived a full year in the harsh environment of outer space aboard (but NOT inside) the International Space Station. This plucky prokaryote is affectionately known by fans as Conan the Bacterium, as seen in this classic 1990s NASA article.
The JAXA (Japanese Aerospace Exploration Agency) ISS moduleKib? has an unusual feature for spacecraft, a front porch! This exterior portion of the space station is fitted with robotic equipment to complete various experiments in outer space’s brutal conditions. One of these experiments was to expose cells of D. radiodurans for a year and then test the cells to see if they not only would survive but could reproduce effectively afterward. D. radiodurans proved to be up to the challenge, and what a challenge it was!
In an expected move, the Japan Aerospace Exploration Agency (JAXA) has announced a mission extension for their Hayabusa2 spacecraft. Hayabusa2 will be sent to rendezvous with another asteroid in a few years time.
It’s target is 1998 KY26, a near-Earth object (NEO) less than a kilometer in diameter. But it’ll take a while and some maneuvering around other objects in the Solar System to reach its goal. JAXA says the spacecraft will arrive at the asteroid in July 2031.
Sending a mission to moons of Mars has been on the wish list for mission planners and space enthusiasts for quite some time. For the past few years, however, a team of Japanese Space Agency (JAXA) engineers and scientists have been working on putting such a mission together. Now, JAXA announced this week that the Martian Moon eXploration (MMX) mission has been greenlighted to move forward, with the goal of launching an orbiter, lander — and possibly a rover — with sample return capability in 2024.
Japan’s Hayabusa 2 mission to asteroid Ryugu has reached one of its final milestones, if not its climax. The sample-return spacecraft has launched the Minerva-II2 rover at the asteroid. This is the last of four rovers that Hayabusa 2 is deploying on Ryugu.
This past Monday (Sept. 16th), Hayabusa2 released two target markers as part of its “target marker separation operation” (which ran from Sept. 12th to Sept. 17th). This consisted of two 10 cm (4 in) balls covered in reflective material being released in orbit around Ryugu. This operation puts the mission a step closer to the deployment of the mission’s MINERVA-II2 Rover-2, which will be landing on the asteroid’s surface next month.
When Japan’s Hayabusa 2 spacecraft arrived at asteroid Ryugu in June 2018, it carried four small rovers with it. Hayabusa 2 is primarily a sample-return mission, but JAXA (Japan Aerospace Exploration Agency) sent rovers along to explore the asteroid’s surface and learn as much as they could from their visit. There’s also no guarantee that the sample return will be successful.
They chose Ryugu because the asteroid is classified as a primitive carbonaceous asteroid. This type of asteroid is a desirable target because it represents the primordial matter that formed the bodies in our Solar System. It’s also pretty close to Earth.
The sample from Ryugu, which will make it to Earth in December 2020, is the big science prize from this mission. Analyzing it in Earth-based laboratories will tell us a lot more than spacecraft instruments can. But the rovers that landed on Ryugu’s surface have already revealed a lot about Ryugu.
