Thecrochetpattern

We launch things into space by putting them on rockets with enough fuel — called propellant — to boost them above most of Earth’s atmosphere. Once a rocket reaches the right distance from Earth, it releases the satellite or spacecraft.

Arctic sea ice reaches its minimum extent (the area in which satellite sensors show individual pixels to be at least 15% covered in ice) each September. September Arctic sea ice is now shrinking at a rate of 12.6% per decade, compared to its average extent during the period from 1981 to 2010. This graph shows the size of the Arctic sea ice each September since satellite observations started in 1979. The monthly value shown is the average of daily observations across the month of September during each year and is measured from satellites. The animated map below shows the minimum size of the Arctic sea ice measured each year since 1979, based on satellite observations. The 2012 sea ice extent is the lowest in the satellite record.

NASA currently has two rovers (Curiosity and Perseverance), one lander (InSight), and one helicopter (Ingenuity) exploring the surface of Mars. Perseverance rover – the largest, most advanced rover NASA has sent to another world – touched down on Mars on Feb.
