Landing On Mars - News Burst Special Edition

Landing On Mars

The Mars Rover Perseverance has almost completed its 293-million-mile (473-million-kilometer) journey to its new home, the Red Planet. In July 2020, a United Launch Alliance Atlas V rocket launched Perseverance from America’s Multi-User Spaceport.

Atmospheric Entry

As the spacecraft enters the Martian atmosphere, the drag produced drastically slows it down – but these forces also heat it up dramatically. Peak heating occurs about 80 seconds after atmospheric entry, when the temperature at the external surface of the heat shield reaches about 2,370 degrees Fahrenheit (about 1,300 degrees Celsius). Safe in the aeroshell, however, the rover gets up to only about room temperature.

Landing On Mars

Now, Perseverance will touch down on Mars to begin its mission of exploring the Martian surface and seeking evidence of ancient life on Mars.

Perseverance is scheduled to land on February 18, 2021 at approximately 20:55 UTC at Jezero Crater. Key timings for Perseverance’s landing:

    • Contact with atmosphere: 20:48 UTC
    • Parachute deployed: 20:52 UTC
    • Powered descent: 20:54 UTC
    • Wheels down: 20:55 UTC

Perseverance will sift and drill into the sediments to look for traces of ancient microbial activity. The most propitious examples will be packaged for return to Earth by later missions.

Of the 14 landing attempts at the planet, eight have been successful – all of them American. Indeed, NASA has only got it wrong once, way back in 1999.

Jezero Crater

Jezero is named after a town in Bosnia-Herzegovina. In some Slavic languages the word “jezero” also means “lake” – which should explain the fascination.

This 500m-deep bowl once saw huge volumes of water flow in through the western wall to pool on the crater floor.

Where the water entered, it even deposited sediments to form a delta. Perseverance will try to land next to this feature.

Jezero displays multiple rock types, including clays and carbonates, that have the potential to preserve the type of organic molecules that would hint at life’s bygone existence.

Mars Ingenuity

One of the wildest aspects of the Perseverance mission is that it will include a helicopter. The small helicopter, named Ingenuity, will ride on the rover’s belly until NASA finds a suitable spot to release it for a test flight.

This image shows the flight model of the helicopter in early 2019. NASA considers Ingenuity a high-risk, high-reward technology demonstration. If it works, it will be a stunning achievement in flight on another planet.

The whales are moving offshore being displaced from their calving grounds. Fewer are being seen year after year around the inside of the Vava’u island group. The whale’s behavior is also changing due to the extreme boat pressure being put on them, becoming more evasive to boats each year. This is not only in Vava’u, many other countries are seeing the impact of tourism based whale activities – and many of those are non-swim operators.

Earth is entering a stream of debris from Halley’s Comet, source of the annual eta Aquarid Meteor Shower. The shower’s peak on May 5th and 6th will be muted by the glare of a nearly full Moon, reducing the number of visible meteors to no more than about 10 per hour. The best time to look is during the hours before sunrise on Tuesday and again on Wednesday.
