Mars class of 2020: A diverse group of missions takes aim at the Red Planet

As many as six missions to Mars might launch in summer 2020, representing a growing and increasingly diverse interest in interplanetary space exploration.

A great time to land on Mars

The 2020 window represents an especially good opportunity for missions looking to reach the Martian surface because of favorable environmental conditions on the planet early in 2021 when the spacecraft will arrive. The elliptical shape of Mars’ orbit means that the planet is, at times, much closer to or farther from the sun, so the amount of sunlight hitting the planet varies dramatically through the Martian year. Meanwhile, the tilt of Mars’ axis, as on Earth, leads to a progression of seasons as the orientations of the northern and southern hemispheres with respect to the sun change regularly and oppositely. The combination of Mars’ orbit and tilt drives an annual cycle of swings in atmospheric pressure of up to about 25 percent as carbon dioxide freezes out of, or sublimes into, the atmosphere.

Making oxygen with MOXIE

The MOXIE (Mars OXygen In-situ resource utilization Experiment) instrument on NASA’s 2020 rover is designed to demonstrate technology that can generate oxygen from carbon dioxide in the Martian atmosphere. Scaled-up versions of the technology could one day be used to produce the large amounts of fuel needed to boost rockets back off the planet’s surface, as well as to create breathing oxygen for human settlements.

Bare Earth Elements: Tour brings hurricane hunting aircraft and expertise to the masses

With hurricane season officially getting under way on May 15 in the Eastern Pacific and June 1 in the Atlantic, NOAA has been busy this week publicizing National Hurricane Preparedness Week, which aims to inform the public about what they can do to prepare for potentially damaging and life-threatening storms. This year, the agency is simultaneously hosting its annual Hurricane Awareness Tour, a week-long traveling exhibition starring hurricane hunting aircraft and their crews. EARTH's Tim Oleson dropped by the tour stop in Washington, D.C., on May 9 to check it out and talk with Rick Knabb, director of the National Hurricane Center.
