Mars

"The red planet"

See All Stories

Mars, named after the Roman God of war, is the second-smallest planet in our solar system. Often referred to as “the red planet” due to its red appearance caused by the iron oxide on its surface. Features of the planet include impact craters, valleys, deserts, and large polar ice caps.

The planet has been explored by many unmanned spacecraft, including Mariner 4, Mars Pathfinder, Mars Express, and many more.

Traditional life here has been deemed as likely, even more so under the surface due to underground water.

Dispatches from NASA: Countdown to Mars kicks off a decade of science and discovery

NASA’s Perseverance lifted off from Kennedy Space Center in Cape Canaveral on July 30. The new Mars rover traveled atop a United Launch Alliance-operated Atlas V rocket. The Countdown to Mars is just beginning, however. The rover’s months-long journey to Mars will continue through February 2021, then the next decade of Martian science and astrobiological discovery can commence. In this Dispatches from NASA installment, Space Explored captures the week that the Mars 2020 mission took flight in photos, video, and more.

Launch Rundown: The path to NASA’s upcoming Mars 2020 Perseverance and Ingenuity mission

On the heels of the return to human space flight from American soil, NASA is launching another historic mission this year. Perseverance, the newest of NASA’s Mars rovers, plans to launch as soon as July 30, and the mission is packed full of new science experiments to learn more about the Red Planet. The new Mars rover will be launching on top of a United Launch Alliance (ULA) Atlas V rocket from Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

What makes Perseverance special? For starters, it’s the result of previous Mars missions dating back to the mid ’90s, and the state-of-the-art rover will be accompanied by the first-ever space helicopter…

White House celebrates SpaceX and Mars Perseverance rover on Space Exploration Day

Neil Armstrong made history 51 years ago today when the American astronaut became the first human to step foot on the Moon. Space Exploration Day on July 20 honors the Apollo 11 mission and all advances made in space.

The White House released a presidential statement this year that recognizes the recent SpaceX launch with astronauts and the upcoming NASA Mars 2020 mission as current milestones:

Mars Perseverance rover launch shifts to July 30 after multiple hiccups, August 5 deadline extended

The window for launching from Earth to Mars opens on July 17. NASA planned to use the date to launch its newest Mars rover Perseverance tasked with finding signs of past life on Mars.

NASA associate administrator Steve Jurczyk shared on June 9, however, that the earliest date launch partner United Launch Alliance can lift off is July 20. The launch date slipped back another two days on June 24 following a “ground support systems issue identified during the packing of the spacecraft into protective fairings that go on top of the rocket.”

As of June 30, however, the current launch target is no earlier than July 30. The original launch target extended through August 5, although NASA and ULA believe they can launch as late as August 15 if needed.

NASA finalizes contract to design habitation and logistics outpost for lunar orbiting Gateway

NASA signed a contract this month with the company that will design its Gateway housing module. The lunar orbiting outpost is intended to be used in NASA’s Artemis program. The Orbital Science Corporation, a subsidiary of Northrop Grumman Space, was awarded a $187 million contract to work on the project. 

The Gateway is an advanced lunar outpost that will be essential to the Artemis program in the future. The program aims to send the first woman and the next man to the Moon by 2024. NASA’s agreement with Orbital Science Corporation foresees that the Gateway’s preliminary design will be presented and revised by the end of this year.

Weekend Reading: “Inside Elon Musk’s plan to build one Starship a week—and settle Mars”

My interest in SpaceX’s Starship mega rocket has been limited so far because the company is still in the build-it-and-blow-it-up phase of assembly, but I have to admit there’s something alluring about huge rockets from any company.

Eric Berger has an in-depth profile on Ars Technica that looks at what exactly Elon Musk’s rocket company is working on with Starship:

Watch: NASA revealing new student-submitted Mars rover name [Update: Revealed]

Curiosity isn’t the only Martian rover making headlines this week. NASA will soon reveal the name of its next Mars rover at a special event held today at 1:30 p.m. ET.

NASA opened name submissions to K-12 students in U.S. public, private, and home schools last August before choosing nine finalists. The agency then conducted an online poll to let the public vote on their favorite name among the top finishers:

NASA’s InSight lander captures over 400 Mars quakes, measures ancient rock magnetism

NASA’s InSight Mars lander touched down one year ago after a six month journey from Earth to the Red Planet. Today six papers were published with a year of science learned through year one of the lander mission.

A new understanding of Mars is beginning to emerge, thanks to the first year of NASA’s InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange magnetic pulses.

Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft’s landing site, a shallow crater nicknamed “Homestead hollow” in a region called Elysium Planitia.

InSight is equipped to detect Mars quakes, wind speed, air pressure, and more.
