While 2021 has been another year of new Covid mutations, the world of science did not disappoint us. The year had many great moments – even milestones. Here are the best moments of 2021 in the world of science.
Jupiter, Saturn and Mercury meet in a triple conjunction
From January 8 to January 12Space.com said the three planets came together in cramped neighborhoods after 30 to 45 minutes after sunset.
NASA’s Perseverance ‘lands on Mars
February 18, 2021, ‘Perseverance’, the largest, most advanced rover ever sent by NASA, became the ninth spacecraft since the 1970s to successfully land on Mars. The car-sized plutonium-powered vehicle arrived at the Jezero crater, hitting NASA’s smallest and most difficult target to date: a 5 by 4-mile strip on an ancient river delta full of pits, rocks and cliffs. Scientists believe that if life ever flourished on Mars, it would have happened 3 billion to 4 billion years ago, when water was still flowing on the planet.
NASA is teaming up with the European Space Agency to bring the rocks home. Perseverance’s mission alone costs nearly $ 3 billion.
Meet Swati Mohan – the Indian-origin lady who landed NASA’s Perseverance rover on Mars
Dr. Swati Mohan. Mohan, the Mars 2020 Guidance, Navigation, and Controls (GN&C) Operations Lead, successfully spearheaded the development of Position Control and the Perseverance landing system.
At NASA’s Jet Propulsion Laboratory near Los Angeles, Swati Mohan communicated and coordinated between the GN&C subsystem and the rest of the project team.
Swati Mohan was the one who confirmed the landing of the Perseverance rover on Mars. “Touchdown confirmed! Persistence is safe on the surface of Mars, ready to start searching for signs of past lives,” she announced shortly after the rover landed.
Swati Mohan emigrated from India to America when she was only a year old. She spent most of her childhood in northern Virginia-Washington DC.

ISRO launches DRDO’s satellite Sindhu Netra
The Indian Space Research Organization on February 28, 2021, launched ‘Sindhu Netra’, a satellite developed by DRDO to monitor the activities of the Navy’s ships in the Indian Ocean.
NASA astronauts complete the fifth spacewalk in 2021
March 14, 2021, the spacewalk, which helped with continued upgrades to the orbiting laboratory, began at 6 p.m. 8:14 ET and ended at. 15:01 ET, and lasted for six hours and 47 minutes. US astronauts Victor Glover and Mike Hopkins arrived at the space station in November as part of the NASA SpaceX Crew-1 mission. This will be Glover’s fourth spacewalk and the fifth for Hopkins.
The spacewalk took place around the one-year anniversary of many Americans being quarantined. Hopkins and Glover addressed the timing in a video released by NASA.
Billionaire Richard Branson reaches Space in his own ship
On July 11th, The dizzying entrepreneur Richard Branson hurried out into space aboard his own winged rocket ship on Sunday, where he knocked out fellow billionaire Jeff Bezos.
The nearly 71-year-old Branson and five crew members from his Virgin Galactic space travel company reached an altitude of about 88 kilometers above the New Mexico desert – enough to experience three to four minutes of weightlessness and see the curvature of the earth – and then safely slipped to a runway landing. Overwhelming entrepreneur Richard Branson hurried into space aboard his own winged rocket ship Sunday, where he knocked out his billionaire Jeff Bezos.
Andhra-born Sirisha Bandla flies into space with billionaire Richard Branson
Sirisha Bandla, a 34-year-old aerospace engineer, flew into space aboard Virgin Galactic’s first fully-fledged flight test. An alumni from Purdue University, Bandla, will evaluate the human research experience using an experiment from the University of Florida that requires several handheld fixation tubes that will be activated at various points in the flight profile.
NASA’s Hubble Space Telescope finds evidence of water vapor on Jupiter’s moon
Astronomers are on for the first time July 21, 2021, uncovered evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede using NASA’s Hubble Space Telescope. This water vapor is formed when ice from the moon’s surface sublimates – that is, turns from solid to gas. The results are published in the journal Nature Astronomy.
Jeff Bezos’ trip to space
Days after the Virgin flight, Blue Origin launched its first manned spaceflight July 20th, with Amazon founder Jeff Bezos and a set of three other space tourists, including Mercury 13 aviator Wally Funk.
Scientists discover light behind black hole
In a groundbreaking discovery on July 29, 2021, scientists have for the first time directly observed light behind a black hole – a scenario predicted by Albert Einstein’s general theory of relativity, but never confirmed until now.
ISRO’s Chandrayaan-2 orbiter finds water molecules on the Moon
In an astonishing new discovery, the home-grown instrument of the Indian Space Research Organization (ISRO) aboard the Chandrayaan-2 has detected the presence of hydroxyl (OH) and water molecules (H2O) on the Moon. Thanks to its 0.8-3 micrometer range, the spectrometer distinguished the two without any ambiguity.
SpaceX joins the club, launching 4 on private ground-circulating tour
SpaceX’s first private flight exploded September 26 with two competition winners, a health worker and their rich sponsor, the most ambitious leap in space tourism to date. It was the first time a rocket had hit an orbit with an amateur crew – no professional astronauts.
Chinese astronauts return after 90 days aboard the space station
A trio of Chinese astronauts returned to Earth last Friday after a 90-day stay aboard their nation’s first space station in China’s longest mission to date. Nie Haisheng, Liu Boming and Tang Hongbo landed in the Shenzhou-12 spaceship just after 1 p.m. 13:30 (0530 GMT) after detaching from the space station d. September 17, 2021.
Persistence reveals the story of the water on Mars
Persistence explored the floor of the Jezero Crater, once a lake and a dried-up river delta at the edge of the crater. Based on the detailed images sent by the six-wheeled rover on Mars, the team has now published the first scientific results about the Jezero crater delta in the journal Science.
The images reveal that billions of years ago, when Mars had an atmosphere thick enough to support water flowing over its surface, Jezero’s fan-shaped river delta experienced flooding in the late stages, bringing rocks and debris into it. from the highlands a good distance outside the crater. .
China launches 3 astronauts on a 6-month space station mission
China on October 15th launched a crew of three people for a six-month mission aboard its space station, which is set to set a new record for the length of time spent in space by Chinese astronauts as the country moves toward completing the orbiting structure.
NASA finds the first signs on the planet outside the Milky Way
On October 26, 2021, NASA’s Chandra X-ray Observatory has for the first time seen signs of a planet passing a star outside the Milky Way, opening a new path to search for exoplanets at greater distances than ever before.
SpaceX launches 4 astronauts to the ISS
On 11 November, A SpaceX rocket has carried four astronauts into orbit, including the 600th person to reach space in 60 years.
Meet Indian-American Raja Chari, one of 3 astronauts selected by NASA for the SpaceX Crew-3 mission
The Indian-American Air Force Colonel Raja Chari has been selected as head of the SpaceX Crew-3 mission to the International Space Station (ISS) by NASA and the European Space Agency.
