I've always been fascinated by the various deep space missions by unmanned probes to the outer system. The recent New Horizons probe, which took the first close up images of Pluto, before entering the Kuiper Belt to reveal its intended target of the dual body object 'Arrokoth' was especially exciting.
Since then, there have not been many major discoveries made but things are about to change over the next few months and years. A number of separate missions are on course to rendezvous with various planetary bodies and asteroids.The most remote object in the current lineup is the asteroid Psyche, which is believed to be largely composed of metal ores. The Psyche probe which was launched in October 2023 is due to arrive at the asteroid in 2029, which is orbiting the sun between Mars and Jupiter. At around 175 miles in diameter, it is quite a substantial target. The probe recently took advantage of a fly by assist from the Martian gravity well and is now accelerating by means of its ion thrusters towards the asteroid belt.The smallest planet in the solar system, Mercury is about to receive a visitor in the shape of the joint ESA and JAXA space probe, Bepicolumbo. Launched way back in October, 2018, the probe has recently arrived in Mercury orbit and will shortly split into two main sections - the European Space Agency's Planetary Orbiter and the Japan Aerospace Exploration Agency's Mercury Magnetospheric Orbiter. The two main components will orbit Mercury seaprately and begin transmitting data to Earth this December, along with close up images of the planets surface.
Back in 2022 the DART spacecraft successfully redirected the course of the asteroid Dimorphos, which had previously been heading for a close pass to Earth. Dimorphos orbits closely around the larger asteroid Didymos. The spacecraft impacted on the surface of the rock and actively changed its orbital trajectory. The idea was to test if it was practical to divert a potentially hazardous Near Earth Object and prevent a collision at some point in the future. Now in 2026, a follow up mission is headed to the asteroids, to inspect the damage caused by the impact. The ESA Hera probe, launched in 2024 will rendezvous with the binary pair and assess the effect of the 'kinetic imapctor'. The HERA probe conducted a flyby of Mars and its moons enroute to the belt and later this month will deploy two separate Cubesats - Milani and Juventas, to study the binary pair and the crater on Dimorphos, left by the action of the spacecraft.
The main probe will continue to orbit the moons, gathering data and hopefully provide an explanation as to how Phobos came to be in orbit around Mars and answer the question as to whether it was originally part of the main planet, formed out of the same material as its parent planet or was captured by the Martian gravity.
Unfortunately, despite successfully achieving lunar orbit and attempting a landing, the laser guidance system failed, 90 seconds before touchdown and the spacecraft crashed on the lunar surface.
The gift my friend sent me was a small model of the rover, supplied to shareholders as a publicity excercise and also issued in the January 2025 Shogakukan Magazine, as a free gift.
The little model is made of cardboard, with plastic wheels and axles and is powered by an elastic band.Like most things japanese, the consruction was well executed, if a little fiddly in places! The model has a foldaway radio mast, opening solar panel and working soil sample scoop on the front. The model itself is probably almost as large as the original rover.

The real Tenacious Rover also carried a small 'art installation' in the form of a small red house model, made by the artist Mikael Genberg. The Lander itself also carried various other cultural artefacts and a memory disk with various messages and information.
