As part of the project named AstroAccess, a group of 12 disabled scientists, veterans, students, athletes, and artists launched into a zero-gravity environment last month.

While 2021 has been another year of new Covid mutations, the world of science did not disappoint us. The year had a lot of big moments – milestones even. Here are the top moments of 2021 in the world of science.

Jupiter, Saturn, and Mercury come together in a triple conjunction

From January 8 to January 12, Space.com said that the three planets came together in tight quarters after 30 to 45 minutes post sundown. 

NASA’s ‘Perseverance’ lands on Mars

On February 18, 2021, ‘Perseverance’, the biggest, most advanced rover ever sent by NASA, became the ninth spacecraft since the 1970s to successfully land on Mars. The car-size, plutonium-powered vehicle arrived at Jezero Crater, hitting NASA’s smallest and trickiest target yet: a 5-by-4-mile strip on an ancient river delta full of pits, cliffs, and rocks. Scientists believe that if life ever flourished on Mars, it would have happened 3 billion to 4 billion years ago when water still flowed 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 who is the Mars 2020 Guidance, Navigation, and Controls (GN&C) Operations Lead, successfully spearheaded the development of attitude control and the landing system for the Perseverance. 

At NASA’s Jet Propulsion Laboratory near Los Angeles, Swati Mohan was communicating and coordinating between the GN&C subsystem and the rest of the project’s team.

Swati Mohan was the one who confirmed the landing of the Perseverance rover on Mars. “Touchdown confirmed! Perseverance is safely on the surface of Mars, ready to begin seeking the signs of past life,” she announced soon after the rover landed.

Swati Mohan emigrated from India to America when she was just one year old. She spent most of her childhood in Northern Virginia-Washington DC.

ISRO launches DRDO’s satellite Sindhu Netra

The Indian Space Research Organisation on February 28, 2021, launched ‘Sindhu Netra’, a satellite developed by the DRDO to monitor the activities of military and merchant navy ships in the Indian Ocean Region.

NASA astronauts conduct fifth spacewalk of 2021

On March 14, 2021, the spacewalk, which assisted with continued upgrades to the orbiting laboratory, began at 8:14 a.m. ET and ended at 3:01 p.m. ET, lasting for six hours and 47 minutes. US astronauts Victor Glover and Mike Hopkins arrived on 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 occurred around the one-year anniversary of many Americans going into quarantine. Hopkins and Glover addressed the timing in a video released by NASA. 

Billionaire Richard Branson reaches Space in his own ship

On July 11, Swashbuckling entrepreneur Richard Branson hurtled into space aboard his own winged rocket ship Sunday, beating out fellow billionaire Jeff Bezos.

The nearly 71-year-old Branson and five crewmates from his Virgin Galactic space-tourism company reached an altitude of about 53 miles (88 kilometers) over the New Mexico desert — enough to experience three to four minutes of weightlessness and see the curvature of the Earth — and then safely glided to a runway landing. Swashbuckling entrepreneur Richard Branson hurtled into space aboard his own winged rocket ship Sunday, beating out fellow billionaire Jeff Bezos.

Andhra-born Sirisha Bandla flies into space with billionaire Richard Branson

Sirisha Bandla, a 34-year-old aeronautical engineer, flew into space onboard Virgin Galactic’s first fully crewed flight test. A Purdue University alumna, Bandla will be evaluating the human-tended 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 vapour on Jupiter Moon

Astronomers have, for the first time on July 21, 2021, uncovered evidence of water vapour in the atmosphere of Jupiter’s moon Ganymede using NASA’s Hubble Space Telescope. This water vapour forms when ice from the moon’s surface sublimates — that is, turns from solid to gas. The findings are published in the journal Nature Astronomy.

 Jeff Bezos’ trip to space

Days after the Virgin flight, Blue Origin launched its first crewed spaceflight on July 20, carrying Amazon founder Jeff Bezos and a set of other three space tourists, including Mercury 13 aviator Wally Funk. 

Scientists detect light from behind black hole

In a groundbreaking discovery on July 29, 2021, scientists have for the first time directly observed light from behind a black hole — a scenario that was predicted by Albert Einstein’s theory of general relativity but never confirmed, until now.

ISRO’s Chandrayaan-2 orbiter finds water molecules on Moon

 

In a stunning new discovery, the Indian Space Research Organisation’s (ISRO) homegrown instrument aboard Chandrayaan-2 has detected presence of hydroxyl (OH) and water molecules (H2O) on the Moon. Thanks to its range of 0.8-3 micrometers, the spectrometer successfully distinguished the two without any ambiguity.

SpaceX joins the club, launches 4 on private Earth-circling trip

SpaceX’s first private flight blasted off on September 26 with two contest winners, a health care worker and their rich sponsor, the most ambitious leap yet in space tourism. It was the first time a rocket streaked toward orbit with an all-amateur crew — no professional astronauts. 

Chinese astronauts return after 90 days aboard space station

A trio of Chinese astronauts returned to Earth on Friday after a 90-day stay aboard their nation’s first space station in China’s longest mission yet. Nie Haisheng, Liu Boming and Tang Hongbo landed in the Shenzhou-12 spaceship just after 1:30 p.m. (0530 GMT) after having undocked from the space station on September 17, 2021.

Perseverance explored the floor of Jezero Crater, which was once a lake, and a dried-out river delta at the crater’s edge.

Perseverance explored the floor of Jezero Crater, which was once a lake, and a dried-out river delta at the crater’s edge. Based on the detailed images sent by the six-wheeler rover on Mars, the team has now published 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 across its surface, Jezero’s fan-shaped river delta experienced late-stage flooding events that carried rocks and debris into it from the highlands well outside the crater.

China launches 3 astronauts on 6-month space station mission

China on October 15 launched a three-person crew for a six-month mission aboard its space station that is planned at setting a new record for the length of time spent in space by Chinese astronauts as the country moves toward completing the orbiting structure.

An exoplanet in M51 would be about 28 million light-years away, meaning it would be thousands of times farther away than those in the Milky Way, NASA said.

 

On October 26, 2021, NASA’s Chandra X-ray Observatory has for the first time spotted signs of a planet transiting a star outside of the Milky Way galaxy, opening up a new avenue to search for exoplanets at greater distances than ever before.

 

SpaceX launches 4 astronauts to ISS

On November 11, A SpaceX rocket has carried four astronauts toward orbit, including the 600th person to reach space in 60 years. 

Meet Indian-American Raja Chari, one of 3 astronauts selected by NASA for SpaceX Crew-3 mission

Indian-American US Air Force Colonel Raja Chari has been selected as the Commander of the SpaceX Crew-3 mission to the International Space Station (ISS) by NASA and the European Space Agency. Chari, 43, will serve as the commander while NASA’s Tom Marshburn will be pilot and ESA’s Matthias Maurer will serve as a mission specialist for the SpaceX Crew-3 mission to the ISS, which is expected to launch next year.
