This ExoMy Mars rover kit is a building project for the holidays

If you’re looking for a fun project for you or your kids this holiday season, then how about building a miniature “Mars rover”?

Don’t worry, the vehicle isn’t full size, and you don’t need millions of dollars to make it happen. You do, however, need access to a 3D printer as well as around $600 to purchase all of the necessary materials.

Created by the European Space Agency’s (ESA) Planetary Robotics Laboratory, the diminutive ExoMy rover is described as the younger sibling of the Rosalind Franklin ExoMars rover, which is set to launch to the red planet in 2022.

Once built, the vehicle stands at 42 centimeters high and includes many of the main features of its 2-meter-tall sibling, including a drill, solar panels across its back wings, and a camera mast. Of course, these features aren’t functional, which at least ensures your littl’un won’t be performing any impromptu drilling work around the house.

Some fun can be had steering the vehicle remotely using a gamepad, or web browser on a mobile device, and unlike the full-size rover, the ExoMy kit includes a “face” and several hats should you feel the need to make your rover look adorable.

The source code for the construction kit is available on GitHub, together with a step-by-step guide on how to put the various printed parts together.

3D print your own Mars rover with ExoMy

“We focused on making the design as affordable and accessible as possible,” ESA’s Miro Voellmy said in an article about the miniature rover. “It uses a Raspberry Pi computer and off-the-shelf electronic parts available online and at any hobby shop. Our hope is that school or university students will make their own ExoMy to become familiar with robotics and learn about the full-sized ExoMars rover.”

He added that the ExoMy rover is a work in progress, with people constantly offering their own suggestions on ways to enhance its design.

The ESA has a special website showing you how to get started on your building project.

The launch of ESA’s ExoMars rover mission has already slipped several times, the most recent change coming nine months ago when the launch date was pushed from this year to 2022. There are, however, three other missions currently heading toward the red planet, launched over the summer by the U.S., China, and the UAE. All three spacecraft are expected to arrive at the faraway planet in February 2021.

Perseverance rover collects its first sample from Jezero delta
This image shows the rocky outcrop the Perseverance science team calls Berea after the NASA Mars rover extracted a rock core and abraded a circular patch. The image was taken by the rover's Mastcam-Z instrument on March 30, 2023.

Things are heating up on Mars, as the Perseverance rover begins its new science campaign. In its previous science campaign, the NASA rover explored the floor of the Jezero crater, but now it has moved on to investigate an exciting location called the delta. As the site of an ancient river delta, this region is a great location to search for evidence of ancient life and to find rocks carried from far-off locations by the river that was there millions of years ago.

Perseverance collected its first sample of this science campaign last week, on Thursday, March 30. This is the 19th sample of rock and dust that the rover has collected so far, with 10 of those samples carefully left behind in a sample cache on the Martian surface. The latest sample was collected from a rock named "Berea" which is thought to be made up of deposits that were carried by the river.

How Europe’s ExoMars rover plans to get to Mars without Russia
ESA’s Rosalind Franklin twin rover is back on its wheels and drilled down 1.7 metres into a martian-like ground in Italy – about 25 times deeper than any other rover has ever attempted on Mars. The test rover, known as Amalia, also collected samples for analysis under the watchful eye of European science teams.

Space missions get scuppered for all kinds of reasons, from engineering problems to budget issues. But the ExoMars mission, Europe and Russia's joint plan to send a rover to Mars, faced a complicated political and ethical issue when Russia invaded Ukraine last year. The European Space Agency (ESA) had been working with the Russian space agency Roscomos on the mission but this partnership was soon suspended over what ESA called the "human casualties and tragic consequences of the aggression towards Ukraine."

Without Roscosmos, the Rosalind Franklin rover was left without a launcher and it was not clear whether the rover would be able to launch at all. But loath to give up on the project, ESA decided it would build its own lander and get the rover to Mars hopefully by 2030. This week, ESA shared more information about the plans for the mission and how it is continuing with testing for the rover.

Rovers could explore lava tubes on Mars or the moon using breadcrumbs
In this artist's impression of the breadcrumb scenario, autonomous rovers can be seen exploring a lava tube after being deployed by a mother rover that remains at the entrance to maintain contact with an orbiter or a blimp.

When looking for safe places for astronauts to stay when they venture away from Earth to new moons and planets, one strong contender is that they should stay underground. Being underground means more protection from harmful space radiation and less exposure to weather events, and nature already creates environments that could be ideal bases in the form of lava tubes. Created when molten lava flows under the surface, lava tubes are thought to exist on both Mars and the moon, providing potential shelter for human explorers.

Now, new research from engineers at the University of Arizona proposes a method for using robots to scout out lava tubes for use as habitats ahead of the arrival of human astronauts. "Lava tubes and caves would make perfect habitats for astronauts because you don't have to build a structure; you are shielded from harmful cosmic radiation, so all you need to do is make it pretty and cozy," said lead author of the research, Wolfgang Fink, in a statement.
