Flying the Ingenuity helicopter on Mars is the equivalent of flying one at about 100,000 feet on Earth. Tricky, considering the highest helicopter flight ever recorded maxed out at 42,000 feet.
Perseverance follows in the tracks of Curiosity. The latter’s touchdown on Martian soil in 2012 marked the first successful use of several pioneering space technologies.
Of the three probes to reach Mars this month, only two will land. But they will add to our growing knowledge of the red planet, and the search for evidence of life.
The atmosphere of Mars is more than 96% carbon dioxide, but the planet is cold because its atmosphere is extremely thin, very dry and further away from the Sun.
If humans are to live on Mars they will need a stable supply of food. Earth plants are not suited to the Mars climate but we can engineer plants that are.
Researchers have found evidence of a large lake of salty water, buried 1.5 kilometres beneath the southern polar ice cap on Mars. So what does that mean for life on the red planet?
Planetary protection protocols try to make sure we don’t seed places like Mars with life from our planet. An astrobiologist argues they’re misguided – especially with human astronauts on the horizon.
