The year 2020 witnessed a lot of exciting space endeavours! From launching multiple Mars missions to collecting samples from the Moon and a space rock2020 was an exceptional year for space exploration, despite unprecedented lockdowns due to COVID-19 pandemic.

Now, with the arrival of the New Year, begins a new space race as countries are gearing up to prove their prowess in cosmic exploration yet again with multiple novel mission launches. As space agencies across the globe fire up the hopes of millions of space enthusiasts, The Weather Channel India has compiled a list of highly anticipated missions of 2021.

Chandrayaan-3: The Indian Space Research Organisation (ISRO) is once again eyeing to land on the Moon in 2021. Though no date has been fixed yet, Indias Moon mission successorChandrayaan-3may be launched sometime in the first half of 2021. The third lunar mission was earlier scheduled for 2020, but the ongoing pandemic and the lockdown imposed to contain the spread of coronavirus stalled its launch. In its second attempt, the Indian space agency is aiming to achieve a soft landing on the south pole of the lunar surface, which is least explored to date. Unlike its predecessor, Chandrayaan 3 will not carry an orbiterbut will include a lander and a rover to study the lunar surface.

Artemis 1: The US space agency NASA is gearing up to return astronauts to the Moon by 2024 and towards this, the first uncrewed test flight is slated for launch in November 2021 under the Artemis program. The mission spacecraft is named Orion, which will be onboard a Space Launch System (SLS) rocket. The mission will carry 13 small satellites to conduct science and technology investigations. As per NASA: the primary operation goal of the mission is to assure a safe crew module entry, descent, splashdown, and recovery.

Luna-25: The Russian space agency, Roscosmos is also gearing to launch a lander mission named Luna-25 to the Moon by October this year. The mission is said to have nine instruments on board with the main objective of exploring the natural resources present on the Moon. The spacecraft is expected to land on the Boguslavsky craternear the South Pole.

Apart from Chandrayaan-3, ISRO is also aiming to launch its first crewless flight as part of its ambitious human spaceflight mission Gaganyaan by the end of 2021. However, no date has been confirmed by the space agency so far. The mission, which was scheduled for the first half of 2021, witnessed repeated delays due to COVID-19-induced lockdowns. The second crewless flight has also been pushed to 2022.

The two crewless flights are scheduled before the maiden human spaceflight launch by ISRO under the Gaganyaan mission. In one of the crewless flights, ISRO has planned to send a humanoid robot named Vyommitra to the low-earth orbit. The robot will mimic the space crew activities set for the human mission to assess the technology prior to the final mission.

In the 21st century, Mars has been the poster planet in space exploration. The planet is a top contender to being a possible host for future human colonies. Several exploratory missions and scientific studies have pointed to a possibility of ancient microbial life on the red planet. Thus, space scientists dont want to leave any stone unturned in finding clues of life and establishing future human colonies. Exploration missions are the key to achieving this!

In July last yearbetween 20 to 30three distinct Mars missions were launched. All three missionsfrom UAE, the US and Chinaare set to arrive at the Martian vicinity by February 2021. The space agencies have set several scientific goals for the missions. Among many, the main aim of the UAE mission is to study the planets thin atmosphere, while both Perseverance and Tianwen-1 will fetch samples of Martian rocks and soil for further analysis.

Construction of James Webb Telescope.

The launch of the James Webb Space Telescopes is on the cards for this year, after decades of hard work in design and construction of the most powerful space telescope till date. After several delays, it is now expected to be launched this year with a tentative date set for October 31 from French Guyana onboard the European Space Agencys Ariane 5 rocket.

The infrared telescope will not be placed around the Earth orbitlike Hubblebut will be positioned at an L2 Lagrangian point in the Sun-Earth orbit about 1.5 million kilometres away from the planet.

The development of the space telescope is a collaborative work of the US space agency NASA, ESA and Canada. It is designed to study various comic objects present in our solar system, investigate the early galaxies, snap through the dust clouds and aid other cosmic observations. It is regarded to be the largest, powerful and complex space telescope, which will carry forward the legacy of the historic Hubble Space Telescope.

Apart from the ambitious Artemis 1 and Mars mission, NASA is also gearing to launch a planetary defence spacecraft called the Double Asteroid Redirection Test or DART. The mission is slated for launch in July this year to test the ability to change the direction of an asteroid, to protect Earth from future collisions. In particular, it will use a kinetic impactor technique to change asteroid motion in space and is expected to experiment on a double asteroid named Didymos. As per NASA, the Didymos primary body is about 780 meters wide, while its secondary body (or moonlet) is about 160-meters in sizesignificant enough to cause large scale impact upon collision with the Earth.

In October, NASA is planning to launch another asteroid mission named Lucy. The mission spanning 12 years will explore 8 different asteroidswith one located in the asteroid belt, and the rest 7 Trojans-asteroids, which share Jupiters orbit. Experts believe that these asteroids are orbiting in these locations since the formation of the solar system and therefore, will help to shed some light on the early history of our solar system.

In 2021, China Aerospace Science and Technology Corporation (CASC) will begin the construction of its permanent Space Station complex. The agency is planning to launch the core cabinet module of the space station in the spring of this year. The station is expected to be constructed over 11 missions, which will include manned flights, as well as cargo spaceship flights. It is expected to be operational by 2022. The space station will be placed in low orbit and is estimated to be one-fifth the mass of the International Space Station. Moreover, the Chinese agency has planned over 40 space launches for 2021.
