NASA’s InSight Mars lander is going into emergency hibernation. If it can’t save its batteries, it could die.

NASA’s $800 million Mars lander is in an energy crisis.

InSight, which landed in a Martian plain called Elysium Planitia in 2018, has detected more than 500 Mars quakes, felt more than 10,000 dust devils pass by, and started to measure the planet’s core.

But over the past few months, InSight has been fighting for its life as the red planet’s unpredictable weather threatens to snuff out the robot.

Unlike other sites where NASA has sent rovers and landers — including the landing spot of the new Perseverance rover and its Mars helicopter — powerful gusts of wind have not been sweeping Elysium Planitia. These winds, called “cleaning events,” are needed to blow the red Martian dust off the solar panels of NASA’s robots. Without their help, a thick layer of dust has accumulated on InSight, and it’s struggling to absorb sunlight.

InSight’s solar panels were producing just 27% of their energy capacity in February, when winter was arriving in Elysium Planitia. So NASA decided to start incrementally turning off different instruments on the lander. Soon the robot will go into “hibernation mode,” shutting down all functions that aren’t necessary for its survival.

The Golden Box That Could Create Oxygen on Mars

MOXIE is already on the Red Planet. It’s now time to test it out.

Humanity’s future on Mars may depend on a golden box about the size of a car battery.

On February 18, NASA’s Perseverance rover landed on Mars with this box, called MOXIE, nestled in its belly.

MOXIE was designed to convert carbon dioxide into oxygen on Mars, and NASA plans to put it to the test within the next few months. If it works as hoped, the instrument could play a key role in getting astronauts home from Mars — and maybe even help them survive while on the Red Planet.

NASA can’t send people to Mars until it knows it can also bring them back, and that means making sure the astronauts have enough rocket propellant for the return trip.

The most straightforward option is to send the propellant — a combination of oxygen and rocket fuel — to Mars with the astronauts.

The first self-sufficient and sustainable cities on Mars could house one million humans

Nüwa, the cliff city on Mars from ABIBOO Studio on Vimeo.

ABIBOO studio has led the architectural design of a self-sufficient and sustainable city on mars that could house one million humans. ‘nüwa’ forms part of an exhaustive scientific work for a competition organized by the mars society, and fully developed by the SONet network, an international team of scientists and academics led by astrophysicist guillem anglada, who headed the discovery of exoplanet proxima-b. considering the atmospheric conditions, ABIBOO chose the side of a cliff on mars to build a vertical city, with the design and construction systems a result of the planet’s harsh conditions. ‘if we were to construct the buildings as on earth, the buildings would tend to explode from the pressure,’ says says alfredo muñoz, founder of ABIBOO. ‘the solar and gamma radiation on mars forced us to build spaces that are not directly exposed to the sky.’

hina’s Tianwen-1 spacecraft successfully initiated its orbit around Mars, reports Zhao Lei for state-run media outlet China Daily. Tianwen-1 entered Mars orbit February 10 just before 8:00 p.m. Beijing time, reports Smriti Mallapaty for Nature.

The orbiter is carrying a lander and a rover that will attempt to touch down on the planet’s surface in roughly three months with the goal of studying Martian geology, soil and searching for signs of water, according to Nature. This achievement marks the first time China has travelled to another planet and its successful completion is a key step on the way to China’s ultimate goal of landing on the Red Planet for the first time.

Hope spacecraft enters Mars orbit, making history for UAE

The United Arab Emirates (UAE) made history on Tuesday when it became the first Arab nation to have a spacecraft reach Mars.

Following a seven-month flight to the red planet, the probe dubbed “Amal,” meaning “Hope,” entered Mars orbit after successfully completing a challenging braking maneuver that allowed it to be caught by Mars’ gravity.

The mission team tweeted confirmation of the spacecraft’s milestone with words: “7 years of work crowned with success!”

NASA’s ‘Mars Helicopter’ Ingenuity will reach the Red Planet next month

Ingenuity and Perseverance should touch down on Mars February 18, 2021

Something to look forward to: NASA’s latest explorer rover is set to make contact with Mars’ surface next month, on February 18. It’s an important step for the space agency, and not just due to the rover itself: its cargo is equally important. The Perseverance rover is carrying the first-ever “Mars Helicopter,” aptly known as Ingenuity.

Ingenuity is a small, lightweight helicopter with two rotors, each made from durable carbon fiber. The rotors will spin in opposing directions, at speeds of “around 2,400 rpm,” which is “many times” faster than what you’d see on any passenger helicopter on Earth.

So, why are those speeds necessary, and why is Ingenuity so light? According to NASA, Mars’ extremely thin atmosphere is to blame. With much less usable air than Earth, any flying vehicle attempting to fly on the Red Planet would need considerably faster rotors to generate enough lift to get off the ground.

NASA video shows Perseverance rover’s planned ‘terror’ landing on Mars

NASA has shown what it will look like when its Perseverance rover touches down on Mars, a challenging sequence that the agency describes as “7 minutes of terror.”

The Perseverance rover was launched in the summer and is scheduled to arrive on Mars in February [2021].

Once it reaches Mars’ atmosphere on its way to Jezero Crater, it must slow down from its speed of 12,000 mph in a span of 7 minutes, touch down on the rust-colored surface and disconnect from the main spacecraft.

Tuesday, NASA released an animation that showed the complex process.

The rover will carry state-of-the-art onboard cameras and microphones that will record the landing for NASA to study — if all goes well.

How NASA Built a Self-Driving Car for Its Next Mars Mission

Like the self-driving cars on Earth, Perseverance will navigate using an array of sensors feeding data to machine vision algorithms.PHOTOGRAPH: NASA/JPL-CALTECH

Later this month, NASA is expected to launch its latest Mars rover, Perseverance, on a first-of-its-kind mission to the Red Planet. Its job is to collect and store geological samples so they can eventually be returned to Earth. Perseverance will spend its days poking the Jezero Crater, an ancient Martian river delta, and the samples it collects may contain the first evidence of extraterrestrial life. But first it has to find them. For that, it needs some damn good computers—at least by Martian standards.

Perseverance is significantly more autonomous than any of NASA’s previous four rovers and is designed to be what Philip Twu, a robotics system engineer at NASA’s Jet Propulsion Laboratory, calls a “self-driving car on Mars.” Like the ones on Earth, Perseverance will navigate using an array of sensors feeding data to machine vision algorithms. But whereas terrestrial autonomous vehicles are packed with the best computers money can buy, the main computer on Perseverance is about as fast as a high-end PC … from 1997. The only way Perseverance’s poky brain is able to handle all this autonomous driving is because NASA gave it a second computer that acts like a robotic driver.

The United Arab Emirates successfully launches its first spacecraft bound for Mars

Today, the United Arab Emirates’ first interplanetary mission successfully took off from the southern tip of Japan, sending up a car-sized probe bound for the planet Mars. The launch marks the beginning of the country’s most ambitious space project yet, aimed at studying the weather on Mars as it evolves throughout the planet’s year.

The spacecraft, called Hope, took off on top of a Japanese H-IIA rocket from Japan’s Tanegashima Space Center at 6:58AM at the launch site (or 5:58PM ET this afternoon on the East Coast of the US). The probe will now spend the next seven months traveling through deep space, periodically correcting its course with a series of engine burns. Then sometime in February of 2021, it’ll attempt to put itself into an elongated orbit around Mars, where it will analyze the atmosphere and climate throughout the course of each Martian day.

For the UAE, the timing of this launch was absolutely critical. The UAE government conceived of this project in 2014 to inspire young Emirati teens, and as a bold way to celebrate the 50th anniversary of the nation’s founding in December 2021. To ensure that Hope is in orbit by the anniversary, the team behind the spacecraft had to launch this summer, during a small window when Earth and Mars come closest together during their orbits around the Sun. This planetary alignment happens once every 26 months, so the UAE team had to launch this year to meet the 2021 deadline.
