2024’s most exciting space missions– Moon’s south pole to ice-covered ocean world

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 all the things goes as deliberate.

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

1. Europa Clipper

NASA will launch Europa Clipper, which can discover one among Jupiter’s largest moons, Europa. Europa is barely smaller than Earth’s Moon, with a floor fabricated from ice. Beneath its icy shell, Europa doubtless harbors a saltwater ocean, which scientists anticipate accommodates over twice as a lot water as all of the oceans right here on Earth mixed.

With Europa Clipper, scientists need to examine whether or not Europa’s ocean could possibly be an appropriate habitat for extraterrestrial life.

The mission plans to do that by flying previous Europa almost 50 occasions to review the moon’s icy shell, its floor’s geology and its subsurface ocean. The mission may even search for lively geysers spewing out from Europa.

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

The launch window – the interval when the mission might 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 return to the Moon. It would ship people to the Moon for the primary time since 1972, together with the primary lady and the primary individual of shade. Artemis additionally contains plans for a longer-term, sustained presence in house 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 the moment deliberate for launch as early as November 2024. However there’s a likelihood it’ll get pushed again to 2025, relying on whether or not all the mandatory gear, equivalent to spacesuits and oxygen gear, is prepared.

3. VIPER to seek for water on the Moon

The VIPER rover to survey water on the south pole of the Moon.

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

Initially scheduled for launch in 2023, NASA pushed the mission again to finish extra exams on the lander system, which Astrobotic, a non-public firm, developed as a part of the Industrial Lunar Payload Providers 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 might present sources 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 all the things from the intense warmth of lunar daylight – when temperatures can attain 224 levels Fahrenheit (107 levels Celsius) – to the Moon’s frigid shadowed areas that may attain a mind-boggling -400 F (-240 C).

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

4. Lunar Trailblazer and PRIME-1 missions

NASA has lately invested in a category of small, low-cost planetary missions referred to as SIMPLEx, which stands for Small, Revolutionary 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, finding out 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 areas of water molecules throughout the globe.

At present, Lunar Trailblazer is on monitor to be prepared by early 2024.

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

PRIME-1 will drill into the Moon – it’s a take a look at run for the type of drill that VIPER will use. However its launch date will doubtless depend upon whether or not earlier launches go on time.

An earlier Industrial Lunar Payload Providers mission with the identical touchdown accomplice was pushed again to February 2024 on the earliest, and additional delays might push again PRIME-1 and Lunar Trailblazer.

5. JAXA’s Martian Moon eXploration mission

The JAXA MMX mission idea to review Phobos and Deimos, Mars’ moons.

Whereas Earth’s Moon has many guests – large 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 predominant science goal is to find out the origin of Mars’ moons. Scientists aren’t positive whether or not Phobos and Deimos are former asteroids that Mars captured into orbit with its gravity or in the event that they shaped out of particles that was already in orbit round Mars.

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

6. ESA’s Hera mission

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

However DART didn’t simply go to these asteroids, it collided with one among them to check a planetary protection approach referred to as “kinetic impression.” DART hit Dimorphos with such pressure that it really modified its orbit.

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

Hera will launch in October 2024, making its manner in late 2026 to Didymos and Dimorphos, the place it’ll research bodily properties of the asteroids.
