From the moon’s south pole to an ice-covered ocean world, several exciting space missions are slated for launch in 2024

The yr 2023 proved to be an necessary one for space missions, with NASA’s OSIRIS-REx mission returning a sample from an asteroid and India’s Chandrayaan-3 mission exploring the lunar south pole, and 2024 is shaping as much as be one other thrilling yr for space exploration.

A number of new missions below NASA’s Artemis plan and Commercial Lunar Payload Services initiative will goal the moon.

The latter half of the yr will function a number of thrilling launches, with the launch of the Martian moons eXploration mission in September, Europa Clipper and Hera in October and Artemis II and VIPER to the moon in November—if every thing goes as deliberate.

I’m a planetary scientist, and listed here are six of the space missions I am most excited to observe in 2024.

1. Europa Clipper

NASA will launch Europa Clipper, which can discover one of Jupiter’s largest moons, Europa. Europa is barely smaller than Earth’s moon, with a floor manufactured from ice. Beneath its icy shell, Europa probably harbors a saltwater ocean, which scientists anticipate comprises over twice as a lot water as all of the oceans here on Earth combined.

With Europa Clipper, scientists wish to examine whether or not Europa’s ocean could possibly be a suitable habitat for extraterrestrial life.

The mission plans to do that by flying previous Europa nearly 50 times to check the moon’s icy shell, its floor’s geology and its subsurface ocean. The mission will even search for active geysers spewing out from Europa.

This mission will change the sport for scientists hoping to grasp ocean worlds like Europa.

The launch window—the interval when the mission may launch and obtain its deliberate route—opens Oct. 10, 2024, and lasts 21 days. The spacecraft will launch on a SpaceX Falcon Heavy rocket and arrive on the Jupiter system in 2030.

2. Artemis II launch

The Artemis program, named after Apollo’s twin sister in Greek mythology, is NASA’s plan to go back to the moon. It’ll ship people to the moon for the primary time since 1972, together with the first woman and the first person of color. Artemis additionally contains plans for a longer-term, sustained presence in space that can put together NASA for finally sending folks even farther—to Mars.

Artemis II is the primary crewed step on this plan, with 4 astronauts deliberate to be on board throughout the 10-day mission.

The mission builds upon Artemis I, which despatched an uncrewed capsule into orbit across the moon in late 2022.

Artemis II will put the astronauts into orbit across the moon earlier than returning them residence. It’s at present deliberate for launch as early as November 2024. However there’s a probability it would get pushed again to 2025, relying on whether or not all the required gear, similar to spacesuits and oxygen gear, is ready.

3. VIPER to seek for water on the moon

VIPER, which stands for Volatiles Investigating Polar Exploration Rover, is a robotic the scale of a golf cart that NASA will use to discover the moon’s south pole in late 2024.

Originally scheduled for launch in 2023, NASA pushed the mission again to finish extra checks on the lander system, which Astrobotic, a non-public firm, developed as a part of the Commercial Lunar Payload Services program.

This robotic mission is designed to seek for volatiles, that are molecules that simply vaporize, like water and carbon dioxide, at lunar temperatures. These supplies may present assets for future human exploration on the moon.

The VIPER robotic will depend on batteries, warmth pipes and radiators all through its 100-day mission, because it navigates every thing from the intense warmth of lunar daylight—when temperatures can attain 224 levels Fahrenheit (107 levels Celsius)—to the moon’s frigid shadowed regions that may attain a mind-boggling -400 F (-240 C).

VIPER’s launch and supply to the lunar surface is scheduled for November 2024.

4. Lunar Trailblazer and PRIME-1 missions

NASA has not too long ago invested in a category of small, low-cost planetary missions referred to as SIMPLEx, which stands for Small, Modern Missions for PLanetary Exploration. These missions save prices by tagging alongside on different launches as what is known as a rideshare, or secondary payload.

One instance is the Lunar Trailblazer. Like VIPER, Lunar Trailblazer will search for water on the moon.

However whereas VIPER will land on the moon’s floor, learning a selected space close to the south pole intimately, Lunar Trailblazer will orbit the moon, measuring the temperature of the floor and mapping out the locations of water molecules throughout the globe.

At the moment, Lunar Trailblazer is on monitor to be ready by early 2024.

Nonetheless, as a result of it’s a secondary payload, Lunar Trailblazer’s launch timing depends upon the first payload’s launch readiness. The PRIME-1 mission, scheduled for a mid-2024 launch, is Lunar Trailblazer’s trip.

PRIME-1 will drill into the moon—it is a take a look at run for the type of drill that VIPER will use. However its launch date will probably rely on whether or not earlier launches go on time.

An earlier Industrial Lunar Payload Companies mission with the same landing partner was pushed back to February 2024 at the earliest, and additional delays may push again PRIME-1 and Lunar Trailblazer.

5. JAXA’s Martian moon eXploration mission

Whereas Earth’s moon has many guests—huge and small, robotic and crewed—deliberate for 2024, Mars’ moons Phobos and Deimos will quickly be getting a customer as effectively. The Japanese Aerospace Exploration Company, or JAXA, has a robotic mission in growth referred to as the Martian moon eXploration, or MMX, deliberate for launch round September 2024.

The mission’s fundamental science goal is to find out the origin of Mars’ moons. Scientists aren’t certain whether or not Phobos and Deimos are former asteroids that Mars captured into orbit with its gravity or in the event that they formed out of debris that was already in orbit round Mars.

The spacecraft will spend three years round Mars conducting science operations to watch Phobos and Deimos. MMX will even land on Phobos’ floor and collect a sample earlier than returning to Earth.

6. ESA’s Hera mission

Hera is a mission by the European Area Company to return to the Didymos-Dimorphos asteroid system that NASA’s DART mission visited in 2022.

However DART did not simply go to these asteroids, it collided with one in every of them to check a planetary defense approach referred to as “kinetic influence.” DART hit Dimorphos with such pressure that it actually changed its orbit.

The kinetic influence approach smashes one thing into an object with a view to alter its path. This might show helpful if humanity ever finds a potentially hazardous object on a collision course with Earth and must redirect it.

Hera will launch in October 2024, making its means in late 2026 to Didymos and Dimorphos, the place it would research physical properties of the asteroids.
