Chandrayaan-3 Launch Delayed Further to 2022

Chandrayaan-3, India's third mission to Moon, is likely to be launched in 2022, ISRO chief K. Sivan has said.
The COVID-19 lockdown has hit several projects of the Indian Space Research Organisation (ISRO) including Chandrayaan-3, which was scheduled to be launched in late 2020, and Gaganyaan, the country's first manned space mission.
Unlike its predecessor, Chandrayaan-3 will not have an orbiter.
Chandrayaan-3 is critical for ISRO as it will demonstrate India's capabilities to make landing for further interplanetary missions.

ISS Launch Honours ''Hidden Figures'' Mathematician Katherine Johnson

A space station supply ship named after the Black NASA mathematician featured in the movie Hidden Figures rocketed into orbit Sunday, the 59th anniversary of John Glenn's historic launch.
Northrop Grumman's Cygnus capsule dubbed the S.S. Katherine Johnson should reach the International Space Station on 22-2-2021following its launch from Virginia's eastern shore.
Johnson died almost exactly a year ago at age 101.
Mrs. Johnson was selected for her hand-written calculations that helped launch the first Americans into space, as well as her accomplishments in breaking glass ceiling after glass ceiling as a Black woman, Frank DeMauro, a Northrop Grumman vice president, said on the eve of lift off. A homework assignment for all of you is to go watch that movie after the Cygnus launch.

Nicaragua Creates Ministry of Extraterrestrial Space Affairs

Nicaragua has created a new National Ministry for Extraterrestrial Space Affairs, The Moon and Other Celestial Bodies, which is drawing amused reactions on social media in a nation that has been struggling since anti-government protests three years ago.
The agency was approved by 76 legislators in the country's congress, which is dominated by President Daniel Ortega's Sandinista Party. Fifteen opposition legislators abstained.

NASA's Perseverance Rover in 'Great Shape' after Mars Landing

The American space agency has successfully landed its Perseverance rover in a deep crater near the planet's equator called Jezero.
"The good news is the spacecraft, I think, is in great shape," said Matt Wallace, the mission's deputy project manager.
Engineers at Nasa's mission control in California erupted with joy when the confirmation of touchdown came through.
The six-wheeled vehicle will now spend at least the next two years drilling into the local rocks, looking for evidence of past life.
Jezero is thought to have held a giant lake billions of years ago. And where there's been water, there's the possibility there might also have been life.

NASA's TESS Discovers Three Hot Planets

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a young star called TOI 451 with three planets revolving around it. The recently discovered mini solar system is located in the Eridanus constellation, which is a part of the Pisces-Eridanus stream.
The star of this system is 400 light-years away from us and is just 120 million years old, which makes it a lot younger when compared to our Sun. The three hot planets orbiting it were discovered while studying images taken by TESS between October and December 2018.
The reason why astronomers are interested in exploring these planets is because their size can help them understand how planetary atmosphere evolves, given the system is not that far off from Earth.

Europa Clipper: NASA's Ocean World Mission Gets Launch Date

A mission to study a moon of Jupiter that could be home to extra-terrestrial life has been given a launch date.
NASA is sending a spacecraft to the icy world of Europa, which holds an ocean under its frozen outer shell.
Scientists have long regarded the moon as one of the most promising targets in the search for life elsewhere in our Solar System.
The Europa Clipper spacecraft will now launch to the Jovian moon in October 2024, arriving in April 2030.
The spacecraft was to have launched on NASA's Space Launch System (SLS) rocket. But the space agency is reported to no longer be considering that launch vehicle.
It will instead lift off on a commercial rocket.
