NASA’s new interactive mosaic shows Mars in amazing detail

NASA has launched a new interactive tool that shows Mars in extraordinary detail and lets you travel between points of interest at the click of a mouse.

The extraordinary Global CTX Mosaic of Mars comprises 110,000 images captured by the Context Camera — or CTX — aboard NASA’s Mars Reconnaissance Orbiter (MRO).

In a post on its website, NASA describes the mosaic as “the highest-resolution global image of the red planet ever created.” To push the point home, it adds: “If it were printed out, this 5.7-trillion-pixel (or 5.7 terapixel) mosaic would be large enough to cover the Rose Bowl Stadium in Pasadena, California.”

It took Caltech’s Bruce Murray Laboratory for Planetary Visualization six years and tens of thousands of hours to develop.

When you visit the mosaic, you’ll be presented with a viewpoint that’s some way above the Martian surface.

At the bottom of the display, you’ll find a bunch of suggestions for places to visit. Start by selecting Jezero Crater, the ancient dried lake bed where NASA’s Perseverance rover has been searching for evidence of ancient microbial life for the last couple of years, and the site of the Ingenuity helicopter’s numerous flights.

Once you’ve had a good look around by using the buttons or mouse to zoom in and out, you can get an excellent idea of the enormous distance between Perseverance and NASA’s other operational rover, Curiosity, by selecting the button for the older vehicle. As you do so, the view will gently elevate and smoothly sweep across the terrain in a similar way to how Google Earth moves between locations.

If you discover something of interest by yourself and want to come back to it later, simply bookmark the location using one of the buttons on the left side of the display.

Jay Dickson, the image processing scientist who led the project and manages the Murray Lab, said of the mosaic: “I wanted something that would be accessible to everyone. Schoolchildren can use this now. My mother, who just turned 78, can use this now. The goal is to lower the barriers for people who are interested in exploring Mars.”

NASA needs a new approach for its challenging Mars Sample Return mission
An illustration of NASA's Sample Return Lander shows it tossing a rocket in the air like a toy from the surface of Mars.

NASA has shared an update on its beleaguered Mars Sample Return mission, admitting that its previous plan was too ambitious and announcing that it will now be looking for new ideas to make the mission happen. The idea is to send a mission to collect samples from the surface of Mars and return them to Earth for study. It's been a long-term goal of planetary science researchers, but one that is proving costly and difficult to put into practice.

The Perseverance rover has already collected and sealed a number of samples of Mars rock as it journeys around the Jezero Crater, and has left these samples in a sample cache ready to be collected.  However, getting them back to Earth in the previous plan required sending a vehicle to Mars, getting it to land on the surface, sending out another rover to collect the samples and bring them back, launching a rocket from the planet's surface (something which has never been done before), and then having this rocket rendezvous with another spacecraft to carry them back to Earth. That level of complexity was just too much to be feasible within a reasonable budget, NASA Administrator Bill Nelson announced this week.

These 3 companies are developing NASA’s new moon vehicle

NASA has big plans for the moon -- not only sending people back to the moon for the first time in over 50 years but also having them investigate the exciting south pole region, where water is thought to be available. The plan is not just for astronauts to visit for a day or two, but to have them stay on the moon for weeks at a time, exploring the surrounding area. And to explore, they can't just travel on foot -- they'll need a new moon buggy.

Today, Wednesday, April 3, NASA announced the three companies developing its new lunar vehicle: Intuitive Machines, Lunar Outpost, and Venturi Astrolab. They'll each develop a lunar terrain vehicle (LTV) that can carry astronauts from their landing site across the moon's surface, allowing them to range further and reach more areas of interest.
