Yesterday, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander reached Mars after a seven months journey. NASA broadcast the landing live, showing the mission control team eagerly watching as the spacecraft entered the Martian atmosphere and began the nail-biting entry, descent and landing (EDL) process.

At exactly 11:52:29 am PST (2:52:59 pm EST) mission controllers received a signal via the Mars Cube One (MarCO) satellites that the lander had successfully touched down. About a minute later, InSight began to conduct surface operations, which involved the deployment of its solar arrays and prepping its instruments for research.

InSight Lander Touches Down! Begins Mission to Unlock the Secrets of Mars

On of May 5th, 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander launched from Vandenburg Air Force Base atop an Atlas V rocket. Over the next seven months, the mission traveled some 458 million km (300 mi) to Mars for the sake of studying its deep interior and learn how this planet – and all the other terrestrial planets of the Solar System (like Earth) – formed.

At 11:47 am PST (2:47 pm EST), after a seven month journey, NASA’s InSight Lander entered the Martian atmosphere to begin the entry, descent and landing (EDL) phase of its mission. Over the course of the next five minutes, the mission controllers at NASA-JPL watched eagerly as the spacecraft went through the careful process of conducting a textbook landing.

Lakes on Mars Filled up so Quickly They Would Overflow Catastrophically Carving Canyons Within Weeks

Roughly 4.2 billion years ago, Mars was a much different place than it is today. It’s atmosphere was thicker and warmer and its surface much wetter. Unfortunately, the planet’s atmosphere was stripped away by solar wind over the next 500 million years, causing the surface to become so cold and dry that it makes Antarctica look balmy by comparison!

As a result, most of Mars’ water is currently locked away in its polar ice caps. But billions of years ago, water still flowed freely across the surface, forming ancient rivers and lakes. In fact, new research led by The University of Texas at Austin indicates that sometimes these lakes would fill so fast that they would overflow, causing massive floods that had a drastic impact on the surface.

It’s Decided, the Mars 2020 Rover Will Land in Jezero Crater

Jezero crater is the landing spot for NASA’s upcoming 2020 rover. The crater is a rich geological site, and the 45 km wide (28 mile) impact crater contains at least five different types of rock that the rover will sample. Some of the landform features in the crater are 3.6 billion years old, making the site an ideal place to look for signs of ancient habitability.

Strange Grooves on Phobos Were Caused by Boulders Rolling Around on its Surface

Back in the 1970s, NASA’s Mariner and Viking Missions were sent out to explore other planets in our Solar System. All three of them (there were two Viking missions) captured images of Mars’ moon Phobos during their travels. They were our first images of the tiny, potato-shaped moon, and the images held a mystery: strange linear grooves on the moon’s surface.

Honey, Where’s the Space Sperm? It’s in Low-Earth Orbit, Dear

It’s always wise to be prepared for a disaster, but space sperm is taking it a little too far. Having things like food, water, and medicines on hand constitutes a reasonable level of preparation. But now one company wants to freeze your eggs and sperm in space.

Mars InSight Lands on November 26th. Here’s where it’s going to touch down

In the course of exploring Mars, the many landers, rovers and orbiters that have been sent there have captured some truly stunning images of the landscape. Between Spirit, Opportunity, Curiosity, the Mars Reconnaissance Orbiter (MRO) and others, we have treated to some high-definition images over the years of sandy dunes, craters and mountains – many of which call to mind places here on Earth.

However, if one were to describe the region where NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander will be landing (on Nov. 26th, 2018), the word “plain” would probably come to mind (and it would be appropriate). This region is known as Elysium Planitia, and it is where InSight will spend the next few years studying Mars’ interior structure and tectonic activity for the sake of learning more about its history.

Planetary Scientists Have Chosen a Few Landing Sites for the Mars 2020 Rover

One solution could be to have the Mars 2020 rover drive from one potential landing site toward another favorite. Credit: NASA/JPL-Caltech

In the summer of 2020, NASA’s Mars 2020 rover will launch from Cape Canaveral and commence its journey towards the Red Planet. Once it arrives on the Martian surface, the rover will begin building on the foundation established by the Opportunity and Curiosity rovers. This will include collecting samples of Martian soil to learn more about the planet’s past and determine if life ever existed there (and still does).

Up until now, though, NASA has been uncertain as to where the rover will be landing. For the past few years, the choice has been narrowed down to three approved sites, with a fourth added earlier this year for good measure. And after three days of intense debate at the recent fourth Landing Site Workshop, scientists from NASA’s Mars Exploration Program held a non-binding vote that has brought them closer to selecting a landing site.

How Science Journalism Helped Me Become a Better Sci-Fi Writer

Hello all. I hope our readers don’t mind that I’m taking a bit of a diversion here today to engage in a little shameless self-promotion. Basically, I wanted to talk about my recently-published novel – The Jovian Manifesto. This book is the sequel to The Cronian Incident, which was published last year (and was a little shamelessly promoted at the time).

However, I also wanted to take this opportunity to talk about hard science fiction and how writing for a science publication helped me grow as a writer. By definition, hard sci-fi refers to stories where scientific accuracy is emphasized. This essentially means that the technology in the story conforms to established science and/or what is believed to be feasible in the future.

So when I set out to write The Cronian Incident, I wanted it to be as realistic as possible, both in terms of technology and setting. Many of the ideas I came up with, and much of the material I drew from, was inspired from my work here at Universe Today. Since I joined the team in 2010 and became a regular member in 2014, I’ve had the chance to write about space-related news, as well as exciting research and scientific breakthroughs.

There’s a Funny Cloud on Mars, Perched Right at the Arsia Mons Volcano. Don’t Get Too Excited, Though, it’s not an Eruption

The ESA’s Mars Express orbiter has spotted a funny cloud on Mars, right near the Arsia Mons Volcano. At first glance it looks like a plume coming out of the volcano. But it’s formation is not related to any internal activity in this long-dead volcano. It’s a cloud of water ice known as an orographic or lee cloud.

The cloud isn’t linked to any volcanic activity, but its formation is associated with the form and altitude of Arsia Mons. Arsia Mons is a dormant volcano, with scientists putting its last eruptive activity at 10 mya. This isn’t the first time this type of cloud has been seen hovering around Arsia Mons.
