Was There Once Life On Mars?  Our Perseverance Rover Aims to Find Out

Our Perseverance mission is set to launch on Thursday, July 30 and could help answer many longstanding astrobiology questions about Mars. The mission will deliver our Perseverance rover to the Martian surface, and this powerful rover is equipped with a multitude of tools to study the planet’s environment and to answer questions about whether or not the Red Planet could have had life in the past.

Was There Once Life On Mars?  Our Perseverance Rover Aims To Find Out

In preparation for launch, our Astrobiology Program is releasing a new update to Issue #2 of the graphic history series, Astrobiology: The Story of our Search for Life in the Universe. This new, fourth edition tells the tale of our exploration of Mars in relation to astrobiology.

The history of our exploration of Mars is full of struggle and triumph. Mars is a dangerous and difficult planet to visit, with frigid temperatures, damaging dust storms, low gravity, and a thin atmosphere. Despite the challenges, NASA missions have opened our eyes to a world that was much more Earth-like in its past, with environments that contained all the necessary conditions for life as we know it.

image

Issue #2 tells the complete history of our endeavours on Mars, from the Mariner missions to Viking and Pathfinder to Curiosity. In this fourth edition, you’ll find  details on the Perseverance rover and its journey to search for ancient signs and signatures of life that could once and for all tell us whether or not life gained a foothold on the ancient Red Planet.

Perseverance will also drill into Martian rocks and collect samples that will one day be returned to Earth by a future Mars Sample Return mission. The samples will be stored in special containers and carefully ‘cached’ in a location on Mars where they will be easily accessible for retrieval. These samples will allow astrobiologists to perform detailed experiments that robots are not yet able to undertake remotely.

Making the Skies Safe for Unmanned Aircraft

Unmanned Aircraft Systems (commonly known as UAS or drones) are typically a smaller aircraft that fly without an onboard pilot. Currently used for research, testing, and aerial-visual purposes, these vehicles could one day carry cargo, or even passengers, through countryside and city landscapes.

image

UAS are a key component of our Unmanned Aircraft Systems Integration in the National Aairspace Ssystem (UAS in the NAS) project. Our research will help develop the rules so that unmanned aircraft can safely coexist with manned aircraft in the national airspace.

image

We collaborate with private companies, like Navmar Applied Science Corporation (NASC), to research and test aerodynamically efficient UAS. We also work with government agencies like the Federal Aviation Administration (FAA) to conduct research that will contribute to setting standards and certifications.

image

We are leading the nation to open a new era in air transportation called Advanced Air Mobility (AAM). AAM will enable safe, sustainable, affordable, and accessible aviation that moves people and cargo between places using a transformed air transportation system and revolutionary new aircraft.

image

With new cost-and-fuel efficient aircraft and technologies becoming available, UAS will provide substantial benefit to U.S. industry and the public. Such benefits include air-lifted organ transplant deliveries that arrive more quickly and safely than ever before; and search and rescue missions performed with increased speed and accuracy.

image

There are other benefits too, like pizza being air- dropped to your front door, and less package delivery trucks on the road. The burgeoning landscape of AAM holds many potentials – and it’s our job to help safely and sustainably map out and navigate what that future landscape looks like.
