Cool ideas in #JAXA #ISASNews this month, including avoiding the "7 minutes of terror" by taking an inflatable down to the surface of Mars, robots to collect lunar samples, a search for dark matter signatures above Antartica, and pondering on the changes the pandemic brought to society.

The full stories (in Japanese) are here: https://www.isas.jaxa.jp/outreach/isas_news/2025/

The Deployable Aeroshell for landing on Mars by Yamada Kazuhiko, Department of Space Flight Systems. Landing on the red planet is considered one of the most challenging aspects to exploring the surface of Mars. The thin atmosphere makes deceleration difficult, turning the descent into the “7 minutes of terror” as multiple steps must be completed flawlessly to land at safe speeds. A possible solution is a deployable aeroshell, which consists of a flexible membrane with a diameter of about 2.5m and a mass less than 4kg. The aeroshell is inflated before atmospheric entry and can slow the descent even at high altitudes and in a thin atmosphere, avoiding the need for additional landing mechanics. This lightweight technology could be used to deploy ultra-small landers across the Martian surface, opening the doorway to a new kind of exploration.

Robots for lunar science by Yoshimitsu Tetsuo. In order to collect scientifically valuable samples, geologists conduct a field survey, with analysis on-site, to select the best material. But on the lunar surface, this will require autonomous exploration rovers that can discover, analyse, and collect samples without support from Earth. LEV-1 onboard the SLIM lander was Japan’s first lunar exploration rover. At 2.1kg, this was compact & lightweight, but with minimum exploration capabilities. The next step involves a highly autonomous 50kg-class rover for the lunar south pole. This can be followed by a 200kg rover designed to traverse more difficult terrain, extract samples, and survive the strong variation in temperatures at low latitudes. The future goal is to develop exploration rovers that can also be used on Mars.

The Antarctic expedition for the GAPS cosmic-ray anti-particle search by Mizukoshi Keita. Observations of galaxies suggest the existence of an unexplained gravitational source called dark matter. Leading theories predict that anti-deuteron particles could be produced thought interactions between dark matter particles. However, such particles are easily affected by the Earth’s magnetic field and cannot pass through the atmosphere. To search for these, the GAPS (General Anti-Particle Spectrometer) experiment therefore plans to use a large balloon for long-term flight in the stratosphere near the south pole. GAPS is an international collaborative research project, using Antarctic circumnavigation balloons operated by NASA. The team visited McMurdo Station in Antartica at the end of last year, but unfortunately weather conditions did not allow for the balloon release. The team will make a new attempt at the end of 2025!

Before and after COVID-19 by Fujiwara Akira. 18 years ago, Fujiwara retired from ISAS and returned to Kyoto. He became involved in the “Cafe Scientifique de KYOTO”, where scientists from various fields give lectures once a month and chat with the public. The cafe had ran since 2004, but the COVID-19 pandemic brought progress to a halt and there were concerns that the event would not continue. However, after a three and half year hiatus, the cafe returned in September 2003, and will soon reach its 200th session. But not everything is the same. Fujiwara notes that while topics remain diverse, there is an increase in discussion on the negative aspects of science, such as environment considerations, which reflect recent times. Since COVID-19, Fujiwara has also participated in courses run on Zoom, and appreciates the benefits of having access to such a wide variety of information from home. However, he notes that there is a risk of becoming cooped up, and regularly runs along the river. He is attempting to run a total of 6,378 km: the radius of the Earth!

SpaceX's Crew Dragon Endurance spacecraft docked with the Harmony module of the International Space Station completing the first part of its Crew-10 or SpaceX Crew-10 mission. After checking that the pressure gets properly balanced, the hatch will be opened to allow Anne McClain, Nichole Ayers, Takuya Onishi, and Kirill Peskov to enter the Station and start their mission, which will last about five months.

#JAXA ISAS publishes a really nice newsletter each month, with updates on current and planned missions, future ideas, and interviews. It's only in Japanese, so I asked if we could publish little English summaries. Here's our first month!

(Full newsletter: https://www.isas.jaxa.jp/outreach/isas_news/2025/)

"Navigation, Guidance & Control for the Comet Interceptor flyby" by Sasaki Takahiro & Sakatani Naoya (JAXA). Comet Interceptor is an ESA-led mission to make a flyby of a long-period comet. JAXA is developing one of the two ultra-small probes that will enable images to be captured from different locations. A flyby is a rapid “one-chance event”. The probe must operate autonomously, with no time for help from ground control, successfully identify and image the comet with minimal prior information, and withstand any collisions from dust. It’s a unique challenge for the team!

ISAS Information (four short news bites): (1) Comet Interceptor development has begun, with testing of the EFM (Electrical & Functional Model) and SQM (Structural Qualification Model) designed to confirm that the JAXA ultra-small probe can properly exchange electrical information with the ESA main spacecraft, and test feasibility of the structure. (2) After achieving a pinpoint Moon landing on January 20, 2024, with a precision of about 10m or less, with one of the world’s lightest lunar landers, the SLIM Project is officially complete! (3) The MAXI 15th Anniversary International Workshop was held at Nihon University in December. MAXI is an all-sky X-ray monitoring instrument mounted to the Japan Kibo module onboard the ISS, making discoveries such as the bright and variable black hole, MAXI J1820+070! (4) Akebono observed the Earth’s magnetosphere for 26 years, completing operations in 2015. The satellite has now re-entered the atmosphere.

"The importance of lunar seismology" by Kawamura Taichi, Institut de Physique du Globe, Paris. Analysis of lunar seismic waves or “Moonquakes” allow exploration of the Moon’s internal structure. While seismometers carried during the Apollo program were informative, the data was complicated by the long vibration and scattering of seismic waves due to the Moon’s sandy regolith and lack of atmosphere and water, and only covered the near side. A next-generation lunar seismic network could use multiple broadband seismometers, which are less affected by scattered waves, distributed globally on the lunar surface, to generate a three-dimensional structure of the inside of the Moon.

Interview with Maru Yusuke, Associate Professor, Department of Space Flight Systems. Born in Hokkaido, Maru Yusuke gained his doctorate in engineering from the University of Tokyo and joined JAXA in 2008. He is an expert in space transport systems. His research explores the development of “spaceplanes” which, unlike rockets, effectively use the Earth’s atmosphere to head into space. Using wind tunnel experiments, Maru studies how a spaceplane can take in air, before compressing and mixing with fuel to burn and generate thrust. Maru works on developing inter-orbit transfer vehicles that fly from a low Earth orbit into deep space, looking at the possibility of standardising parts to reduce cost.

This evening Phil Eklund's crowning achievement (or at least one of them) is back on the table! High Frontier 4 All is a complex, complicated, pretty long to play game, with a steep learning curve. But it's extraordinary! A "realistic space exploration in a box". Why do I love it so much? I wrote about it a few months ago on my website:
