On Thursday, NASA’s Perseverance rover is predicted to land at the Jezero Crater on the superior planet, when that it’ll resume work to seem for signs of past life.
Landing is that the shortest however one in every of the foremost vital and conjointly troublesome phases of the mission. NASA says that as a result of it’s troublesome, solely forty % of the missions ever sent to Mars by area agencies across the planet are thriving as a result of “hundreds of things” ought to go right for the suspenseful drop.
To give some context to the issue of launching missions like this one, there’s the instance of analysis man of science Katherine Johnson. within the 2016 film Hidden Figures, Taraji P. puppeteer contend Johnson UN agency worked to work out precise calculations that determined the flight of the capsule that may launch senator into area in 1962.
Other missions to Mars
Another Mars mission, the UAE’s Al Amal (Hope)–the Arab world’s 1st such mission–entered the Martian orbit last week. However, this can be associate orbital mission and doesn’t involve landing on the planet’s surface. with the exception of the UAE, China conjointly launched a Mars mission throughout the July-August window.
In lightweight of such bold area missions, some astrobiologists have expressed considerations regarding attainable ‘interplanetary contamination’. this suggests transporting Earth-based microbes to different celestial bodies and delivery extra terrestrial microbes back to Earth. The Committee on area analysis (COSPAR) lays down a ‘planetary protection policy’ that aims to limit the quantity of microbes sent to different planets, in addition as making certain that alien life doesn’t cause mayhem on Earth.
How will a space vehicle reach Mars?
Typically, a visit to Mars, that is regarding three hundred million miles away, takes regarding seven-eight months. Perseverance was launched on Gregorian calendar month thirty, 2020 throughout the window once Mars and Earth were the nighest to every different. This window is very important since 2|the 2} planets orbit round the Sun at totally different speeds and each two years, the planets area unit in a very position wherever they’re the nighest to every different. area agencies look to launch their space vehicle throughout this window since the nearer distance suggests that exploitation less propellent.
