Mars exploration will get a big boost next summer.
Earth and the Red Planet align favorably for interplanetary travel just once every 26 months, for a few weeks at a time. The next such window opens in mid-July 2020, and four big-ticket missions aim to take full advantage.
NASA’s car-size Mars 2020 rover is scheduled to lift off on July 17. The European-Russian ExoMars rover, named Rosalind Franklin after the renowned scientist, will follow suit eight days later, if all goes according to plan. Both vehicles will touch down in February 2021, hunt for signs of Martian life and perform a variety of other tasks.
For example, Mars 2020 will cache samples for future return to Earth and demonstrate new tech that generates oxygen from the carbon-dioxide-dominated Martian atmosphere — gear that would be very useful for astronauts exploring the Red Planet.
Mars 2020 will also tote a tiny helicopter scout, potentially laying the foundation for extensive aerial Red Planet exploration down the road.
China also aims to hit the mid-2020 launch window with its Mars Global Remote Sensing Orbiter and Small Rover mission, also known as HX-1. As the name suggests, this effort will include both an orbiter and a rover, which between them will carry 13 science instruments, SpaceNews reported in May.
The solar-powered rover will weigh 530 lbs. (240 kilograms), according to SpaceNews. That’s about twice as much as China’s Yutu moon rovers, two of which have landed on the moon — in December 2013 and January 2019, on the Chang’e 3 and Chang’e 4 missions, respectively. (Chang’e 4 pulled off the first-ever soft touchdown on the moon’s mysterious far side.)
HX-1 will be China’s second attempt at a Mars mission. The nation’s Yinghuo-1 orbiter rode piggyback with Russia’s Phobos-Grunt sample-return mission, which launched in November 2011. But Phobos-Grunt never made it out of Earth orbit, and that spacecraft and Yinghuo-1 died fiery deaths in our planet’s atmosphere in January 2012.
The fourth 2020 mission comes courtesy of another Mars debutante, the United Arab Emirates. The UAE’s Hope Mars Mission, also known as the Emirates Mars Mission, will lift off from Japan atop an H-IIA rocket and get to the Red Planet in early 2021 — the year the UAE turns 50.
The mission “aims to collect information on Mars’ meteorological layers and study the causes of loss of hydrogen and oxygen gases, the two main constituents of water, from the upper layer of the Martian atmosphere,” the UAE’s Gulf News reported Tuesday (July 24).
These newcomers will push Mars’ robotic population into the double digits. There are currently two operational craft on the Martian surface (NASA’s Curiosity rover and InSight lander) and six orbiters circling the planet (NASA’s MAVEN, Mars InSight and Mars Reconnaissance Orbiter; Europe’s Mars Express and the European-Russian ExoMars Trace Gas Orbiter; and India’s Mars Orbiter Mission).
