Mars Curiosity rover detects organic molecules on the surface of Red Planet

By instructing NASA's Mars Curiosity rover to mix a sample of Martian dirt with chemical reagents inside a cup, a team of researchers successfully analysed a sample of Martian dirt initially picked up by the rover in March 2017.

According to Inverse, this combination then produced organic molecules that NASA has never discovered on the surface of Mars previously.

While this is an intriguing discovery, it does not prove that carbon-based life existed on Mars' surface.

However, it is a step in the right direction. 

"This experiment was successful," Maëva Millan, a postdoctoral fellow at NASA’s Goddard Spaceflight Center and lead author of a new study published on Monday in the journal Nature Astronomy, said.

Organic molecules are the building blocks of life on Earth, and they might be found elsewhere in the cosmos as well.

The Curiosity rover has already found organic compounds buried in Martian sediments, but the latest discoveries add to the list of organic molecules found on Mars, supporting the argument for past habitability. 

The researchers are looking forward to the launch of the European Space Agency's ExoMars mission in 2022, which will collect further samples from Mars.

The Perseverance rover is also gathering samples from the Martian surface, which will be sent to Earth and studied in a laboratory.

All of the many Martian missions contributed to the mystery of Mars' history, including whether or not the Red Planet has ever harboured life and if that life has spawned life on Earth.

Heinz begins new range of sauce that is created in the same conditions as Mars. Created by Astrobiologists in a special greenhouse called the redhouse. The redhouse simulates conditions on Mars with heat and soil differences. The special sauce is named the no 57 range. Will not be for sale to the public but will be launched to the international space station ISS.

How to use NASA's APOD API

Image
  Nasa publishes one astronomy-related picture(or videos sometimes) every day, i.e., Astronomy Picture of the Day. But do you know? That there is an API that lets you access that information, and you can make a website out of it? So I recently tried doing that, and   this   is what I was able to come up with. And here are the steps so you can do it too. 1.Get your API key: You can get your unique API key from  https://api.nasa.gov/  .What you need to do is just sign up and this website will generate your API key. We will need this key to use this API which has an Hourly Limit of 1,000 requests per hour. 2.Let's get done with HTML first There are a few things for which we want to make space in our HTML Doc. And those things are title, date picker, date(yyyy-mm-dd), copyright, image/video URL, HD URL in case of the image, explanation about image or video, and footer if you want to add your social handles or something. so this will be our code inside the  <body>  of the HTML. &
