As part of the project called AstroAccess, a group of 12 disabled scientists, veterans, students, athletes and artists launched 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 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.

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.

Persistence explored the floor of the Jezero Crater, once a lake and a dried-up river delta at the edge of the crater.

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.
