See both of NASA’s explorers, Curiosity and InSight, on the surface of Mars

The HiRISE camera on NASA’s Mars Reconnaissance Orbiter got its best view yet of the InSight lander on September 23, 2019. NASA/JPL-Caltech/University of Arizona

NASA’s Mars Reconnaissance Orbiter (MRO) is currently in orbit around the red planet and is snapping photos of its surface using an instrument called the High-Resolution Imaging Science Experiment (HiRISE). Recently, HiRISE imaged not just one but both of NASA’s missions which are on the planet right now.

First up, HiRISE took the image above showing the most detailed aerial view yet of the InSight lander. The greenish speck in the middle of the image is the landing site in the Elysium Planitia region, and you can see the two circular panels that the lander uses to collect solar power. Just below the lander, you can see the dome of the heat shield covering the seismometer which is listening out for marsquakes.

This animation shows the position of NASA’s Curiosity rover as it journeyed through “the clay-bearing unit” on Mars between May 31 and July 20, 2019.

This is not the first time that HiRISE has spotted Curiosity on the surface of Mars. In an image released in July this year, HiRise saw Curiosity in a location called Woodland Bay, part of a region called the clay-bearing unit in Mount Sharp. That image was detailed enough that you could even make out Curiosity’s mast which holds instruments like the ChemCam for analyzing rock samples.

Curiosity is still in the clay-bearing now, though it will soon be moving on to a new area called the sulfate-bearing unit. Between May and July, the rover traveled 1,106 feet (337 meters) from Woodland Bay to a new location called Sandside Harbour. In the animation above, Sandside Harbour is in the middle near the bottom of the image, next to the dark patch of sand. Above the rover, you can even make out the tracks left by Curiosity as it moved through the area.

Curiosity is now collecting data about the composition of rocks in the area, in order to learn more about the history of water on Mars and whether the planet was ever capable of supporting life.

Fitbit Charge 4 review

Fitbit has been producing fitness trackers for over a decade, with its products consistently considered as some of the best in its space.In March, Fitbit announced its latest premium fitness tracker, the Fitbit Charge 4, the first Fitbit tracker to feature a built-in GPS.I have been using the Fitbit Charge 4 for about a week now, and am now able to share my impressions of the deviceSetting Up The Charge 4 Fitbit Charge 4 Unboxing and Setup 1 of 10 Front of Box Back of Box What's Inside Extra Band for larger wrists Clip-on charger Fitbit app setup page 1 Setup Page 2 Setup Page 3 Setup Page 4 Feature List In the box was the Charge 4, an extra band that meant for larger wrists, and the charger, which clips to the device.The Charge 4 came mostly charged, so I could setup almost immediately, and I had already set up the Fitbit app prior to receiving the watch.You will have to create an account to use the Fitbit app but it may take around ten minutes. This includes account creation through pairing and a firmware update.DisplayThe Fitbit Charge 4 has a grayscale display, much to the dismay of many a reviewer. However, I heavily disagree that this is a bad thing. I do not want my fitness tracker to be a beautiful distraction. I want it to track my fitness. That being said, the display is easy to see in any lighting and the brightness automatically adjusts to the environment.The watch also has many watch faces that you can switch between, with the one pictured above being called Rightful Stats.Sleep TrackingThe Fitbit Charge 4 features sleep tracking, with a pretty extensive breakdown in addition to a Sleep Score. The sleep tracking page gets a slight layout change for Fitbit Premium users, as you will see below.The Fitbit Charge 4 also features an SPO2 sensor that works during sleep. The SPO2 sensor is meant to measure blood oxygen variation, which can help identify breathing issues during sleep Fitness TrackingThe Fitbit Charge 4’s main selling points as far as fitness are its integrated GPS and the new measurement system known as Active Zone Minutes. Although my walks don’t exactly create the most beautiful map, here is one of my walks including the breakdown of heart zones and pace. It is important to note that the GPS isn’t in use unless you initiate an exercise from the watch prior to starting it. Exercise Tracking 1 of 6 BatteryThe Fitbit Charge 4 touts a pretty solid mixed-use battery life, lasting around four days. This is where the embedded GPS hurts. With it on, the battery life drains dramatically.The GPS is only activated when an exercise is in progress and Fitbit says this only lasts around five hours. Though, with a half-hour walk every day, the battery lasted almost four full days. However, the Charge 4 recharges in around four hours, so if it dies, you aren’t without it for too long.General UsabilityThe Fitbit app is unremarkable and looks fairly similar to any other fitness app, mostly reminding me of the UI of Samsung Health, as shown side by side below. Each of the items that appear on the Fitbit app homepage are able to be moved around to better suit your particular needsThe watch is not completely waterproof, though it is “swimproof”, to use Fitbit’s term, and is water resistant to 50M.The watch face is customizable, with the one shown in the display section being called Rightful Stats. For the watch itself, there are about 10 alternative bands available on the Fitbit website at the time of me writing this article, and they will run you anywhere between $30 and $50.AvailabilityYou can purchase the Fitbit Charge 4 for $150 at the Fitbit website in Black, Rosewood, and Storm Blue/Black or at Best Buy in Black and Rosewood.
