The biggest events around Earth, the Moon, Mars and beyond for 2020

Thursday, January 2nd 2020, 6:00 pm - It's another busy year in space exploration!

This year is setting up to be an amazing one for astronomy and space exploration. There are some spectacular sights to behold in the night sky. New robotic missions are leaving for the Moon and Mars. Plus, we may even see humans launching into space aboard two (or maybe even three) new spacecraft.

Here are the major events happening in 2020.


The very first event in our night sky, on Earth, is the Quadrantid meteor shower, which peaks on the night of Friday, January 3. The best time to watch will be in the hours after midnight, once the first quarter Moon has set. As one of the best meteor showers of the year, the Quadrantids can deliver around 120 meteors per hour under ideal conditions (clear, dark skies, far from city light pollution).

SpaceX is planning another launch for its Crew Dragon spacecraft, but this flight will be the very first to carry astronauts - specifically Doug Hurley & Bob Behnken - up to the International Space Station. While there may be another delay for this launch, it is expected to take place sometime in February.

Look up in the night sky on April 7 to see the biggest and brightest Full Moon of the entire year. This year's Pink Moon just so happens to be 2020's 'Perigee Full Moon' (aka Supermoon), or the closest Full Moon of the year. Due to being around 28,000 km closer to Earth than average, the Moon will appear slightly bigger, but noticeably brighter, all night long.

In June, Boeing's CST-100 Starliner is scheduled to make its first crewed test flight to the Space Station. Given the unexpected complication from its first uncrewed launch, late last year, this flight may be pushed to later in the year.

The Perseid meteor shower will peak on the night of August 12. Although the phase of the Moon is not the most ideal for this shower (third quarter, rising around midnight), this is consistently a great sight to get out and see.

When you're out trick-or-treating on October 31 this year, take a moment to look up to see a 'Halloween Mini Blue Moon'. The Full Moon on the night of October 31 will be the second Full Moon of that month, and it will also be 2020's 'Apogee Full Moon' - the farthest, and thus smallest and dimmest, Full Moon of the year.

Finally, on December 14, we will not only be treated to a Geminid meteor shower that will be taking place on the night of a New Moon (and thus have the best viewing potential), but Chile and Argentina will see their second Total Solar Eclipse in two years!

As a bonus, SpaceX may be launching its Falcon Heavy rocket before the year ends, and Japan's Hayabusa 2 spacecraft is due to drop off its sample-return capsule, with samples collected from Asteroid Ryugu, in December.


We saw something of a rush to get back to the Moon in 2019, and that trend will continue in the year to come.

Although the Moon Express team did not complete their mission in time to win the Google Lunar Xprize, they are still planning on launching their Lunar Scout lander, with its International Lunar Observatory, sometime in 2020. The current schedule for this launch is in June or July, with a landing near the Moon's south pole likely later this year.

In the late months of this year, things are expected to get very busy in Lunar orbit and on the Moon's surface. Before the end of 2020, we will likely see the launch of China's Chang'e 5 lander and rover, India's Chandrayaan-3 lander, and NASA's CAPSTONE lunar orbiter, which will test the long-term stability of the planned Lunar Gateway station.

We may even see a launch of the Artemis 1 mission, which is an uncrewed flight of NASA's Orion spacecraft on a trajectory around the Moon and back to Earth, and SpaceX has ambitious plans to send its Starship spacecraft on an orbital flight before the year is over.


Mars' population of active robots dropped by one in 2019, but the Curiosity rover and InSight lander will soon have more friends on the Martian surface.

In July of this year, everything is going to line up perfectly to launch spacecraft from Earth and Mars, and there are currently four different missions on the schedule to take advantage of that critical window of opportunity.

NASA's Mars 2020 rover (soon to be renamed) is the first on the schedule, set to lift off from Kennedy Space Center on July 17. If everything goes as planned, that launch will put it on course to reach Mars and land in Jezero Crater on February 18, 2021. Once it arrives there, the rover and its tiny helicopter companion will set about exploring what was once a river delta on Mars, in the hopes of finding evidence that life once lived on the Red Planet.

The ESA's ExoMars 2020 rover, which includes the Rosalind Franklin rover, is scheduled to launch on July 26, with a landing date in March 2021, in Oxia Planum, to the northeast of Mars' famous Mariner Valley. The rover's mission is similar to Mars 2020's, and it has a suite of instruments dedicated to searching for signs of past and present life.

China is planning on sending their Mars Global Remote Sensing Orbiter and Small Rover (aka Huoxing 1) mission to land, most likely in Utopia Planitia, sometime likely in April of 2021. With Huoxing 1 (which means Mars 1) also searching for signs of life, past or present, this really could be the year we find evidence of life on Mars!

Rounding everything out, the United Arab Emirates plans to launch an orbiter spacecraft, called the Hope Mars Mission, to study Mars' atmosphere, weather and climate.


Nothing new is launching to Jupiter in 2020 (we have to wait until at least 2025 for that), but NASA's Juno spacecraft is still looping around the giant planet. It is set to make seven more close approaches ('perijoves'), between mid-February and late December 2020.

To see what a 'perijove' flyby looks like from Juno, watch the above video. The images that went into making the video were snapped by JunoCam during perijove 16, on October 29, 2018.


Things are getting exciting again for the OSIRIS-REx spacecraft, currently orbiting Asteroid Bennu, out in interplanetary space.

It's been just over a year since the spacecraft arrived at its destination. It has already produced some amazing maps of immense 'rubble pile' Bennu and noted some particular strange science going on there.

In 2020, it will make its first attempt to touch the surface of the asteroid, and blast off a small sample that it will collect for return to Earth.

Of the four locations on the surface that the mission team chose - nicknamed Nightingale, Kingfisher, Osprey and Sandpiper - the Nightingale site was finally selected as the primary site for this sample collection.


Given that the Sun is our closest star, it's remarkable how much we still have to learn about it.

NASA's Parker Solar Probe is still going strong on its dives into the solar corona, sending back new data that will help us track space weather and the solar wind. In 2020, PSP is set up to make three close passes around the Sun.

Its December 26 Venus flyby now has the spacecraft on a trajectory for its two closest loops yet, with its perihelion distance down to 19.4 million kilometres for the January 29 and June 7 passes (down from 24.8 million kilometres in 2019). It will then make its third (and second-closest) Venus flyby of the mission in July, which will take it even closer to the Sun - 14.2 million km - for its September 27 perihelion.

Parker Solar Probe is due for some company this year, as well. The European Space Agency's Solar Orbiter is set to launch in early February (on the 5th or 6th), on a 7-year mission to study the solar wind and the inner region of the Sun's heliosphere (the bubble of space contained within the Sun's immense magnetic field).

Solar Orbiter won't get as close to the Sun as the Parker Solar Probe, only coming to around 42 million kilometres distance on any particular close pass. Still, it should be able to coordinate observations with PSP, especially during events like solar flares and coronal mass ejections (aka solar storms).
