2020 is our best bet for finding life on the red planet.
The Perseverance Rover (Mars 2020) installed within the upper stage of the United Launch Alliance rocket that will send it to Mars from Florida this week.
Australian scientists have been working on NASA's latest Mars mission for years.
In a clean room at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., engineers observed the first driving test for the Mars rover, Perseverance. Perseverance will search for signs of past microbial life, characterize Mars’ climate and geology, and collect samples for a future return to Earth.
This summer, NASA's Mars Perseverance rover is taking the next giant leap in our search for signs of life beyond Earth.

Martian meteorites allow scientists here on Earth to decode that planet's geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
Over the last 50 years, a lot has changed in rocketry. The fuel that powers spaceflight might finally be changing too.

The InSights mission is producing the first evidence-based picture of Mars's interior.
As plans for space exploration expand, how will sex and desire be addressed in these larger, longer missions?
Sex technologies and 'erobots' could help address issues related to human desire, and physical and emotional needs of astronauts in space.
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) is a research facility designed to simulate conditions on Mars.
In preparation for possible future missions to Mars, scientists figure out how to quickly and efficiently measure brain performance and mental fatigue.

SpaceX’s Dragon 2 will carry humans for the first time in 2020.
From alien life to human spaceflight, 2020 may deliver some exciting news.
In 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.

Collecting samples from Mars and brining them back to Earth will be a hugely complicated task, but it may be our best bet of finding alien life.
