Day in the Life of the Curiosity Rover on Mars
by Dr. Bethany Ehlmann

In our book, Dr. E has a robotic sidekick, Rover, who helps Dr. E. operate her spaceship to jet around the solar system, analyzing samples, beeping questions, and generally stealing the show with the cutest side comics of planetary exploration adventures.

In real life as Dr. Bethany Ehlmann, planetary geologist, I have the privilege of serving on NASA’s Mars Science Laboratory Curiosity team. My role as a scientist is to help direct the exploration: which way to drive, which rocks to look at up close, and which rocks to drill. Curiosity’s day on Mars is not quite that of Rover in the book, so let’s talk about a day in the life of an actual rover on Mars.

At about 7am, Curiosity is asleep but the sun has brightened the sky and is peeking up over the 5-km tall Mt. Sharp in the center of Gale crater. Having already driven about 18 kilometers, crossing a field of sand dunes, Curiosity is presently working on ascending Mt. Sharp (as of this writing, she is at an elevation of 300 m above the crater floor).

But though the sun’s up, Curiosity has still more sleep. The rover’s awake time is usually after 9:30am. This is not because it’s a lazy Saturday morning on Mars. It’s because the temperature at sunrise is about -80 °C. Brrrr! The reason Curiosity stays put is an engineering one: to move her joints, Curiosity has to heat every single one of them. And it’s just not an efficient use of the rover’s energy resources for the day. So we patiently wait as the sun warms the air to reach a still-not-so-balmy -30°C to get moving.

Curiosity wakes up with Earth in control. This means Curiosity immediately turns its antenna to receive a packet of computer commands sent from the science and engineering team, who worked over the Mars night to put the plan together. After the plan is received, Curiosity independently executes the entire sequence of the day, laid out line by line in computer code.

There are usually about 10 minutes of engineering activities—data storage checks, reports of hardware status, deletes of data and old sequences—to start the day. This so-called “housekeeping” is kind of like waking up, getting out of your pajamas, brushing your teeth…all those little activities that get you ready to really live the day.

So what does a day hold for Curiosity? Well, it depends. Here’s an example: Curiosity might wake up, turn on her weather station to download and store the data collected overnight, all the while heating her arm joints and cooling the ChemCam instrument. Then Curiosity measures some interesting veins and fractures in the rock 2-7 m in front of her using the ChemCam laser. Her cyclops eye turns to take an image, focus the laser, and zap!, zap-zap!, thirty times, vaporizing the rock and measuring emitted light from plasma. Often we repeat the same 30-shot sequence at 5-20 spots on a rock to understand what the rock is made of in different places.

At 10:30am, Curiosity stretches out her warmed-up arm, moving the turret head in rover tai chi to maneuver its Alpha Particle X-ray Spectrometer into place over a different section of rock. APXS acquires very detailed chemistry using x-rays generated by the instrument. After 30 minutes of x-ray collection, the tai chi begins again to switch the turret to deploy the microscopic imager. First from afar (25 cm from the ground) then closer and closer until the imager is only 1-2 cm above the surface, the rover gets better and better pictures of the rock. Try this with your smart phone of the next cool rock you see….but it won’t be as good as Curiosity’s microimages.

Having done that morning science workout, it’s now high noon and time for Curiosity to hit the road. Curiosity tucks her arm and turret back into her body and slowly rolls toward the x,y,z point on Mars designated by the team on Earth. This is most definitely not a sprint. Curiosity usually travels about 50 m in about 2 hours. By comparison, Usain Bolt crosses that same distance in about 5 seconds while sprinting, and you might walk it in a minute. Curiosity is the ultimate tortoise, proceeding in low gear at low speed to give her enough torque to overcome any obstacle and doing onboard image processing to check for obstacles (pointy rocks, sandy hollows) and safely avoid them. There is no roadside service on Mars….

At about 3:30pm, Curiosity stops the drive. It’s getting cold again. Moreover, we need to have enough time to snap a panorama to send in an afternoon communications link pass to Earth so that the science and engineering team have enough data to plan the next day. Point, shoot, point, shoot, and the detailed imagery is uplinked to Earth between 3-5pm, with the timing set by overhead flybys of NASA’s Mars orbiters, which provide data relay.

And the day is done! Curiosity will keep monitoring weather overnight. She’ll wake up a few times to continue sending back to Earth the important but less-critical-for-next-day’s-planning chemistry and additional image data. Meanwhile on Earth, the team pores over the images and results of the day’s drive to plan tomorrow. Maybe tomorrow we will drill instead of image? Do a ChemCam extravaganza for composition? Or drive as far as we can?

Curiosity might not jet around on a space ship like Dr. E’s sidekick rover, but she is the best eyes and ears on another planet we’ve got. She gets a new view of a new spot on Mars every day.

Spy on History: Victor Dowd and the World War II Ghost Army 
by Enigma Alberti 
January 23, 2018 
Source: from pub 

VICTOR DOWD AND THE WORLD WAR II GHOST ARMY follows Victor and the rest of the Ghost Army in their attempt to take back France from the Nazis as part of a top-secret military unit trained to draw attention from the real deployments. Victor and his fellow soldiers in the unit haven't been trained for combat but have specialized skills that allow them to create fake radio transmissions, dig trenches, and simulate the sights and sounds of real troops. Handpicked for their artistic and creative skills, the Ghost Army used everything from inflatable guns (to draw fire from the German artillery) and inflatable tanks (covered with slightly damaged camouflage netting so they were partially visible) to building fires and hanging up laundry (to make it look like troops were camped nearby) in their war of deception. 
SPY ON HISTORY also includes an enriching interactive element: spy craft materials that make readers part of the story as honorary spies. Readers collect clues embedded in the illustrations and text to uncover the mystery of Victor Dowd’s missing sketchbook, using: 
·         A red acetate sheet 
·         A cipher wheel 
·         A WWII “poop sheet,” collecting information about specific units 
·         A vellum featuring the insignia patches of the Ghost Army and the battalions they impersonated 

About the Victor Dowd and the World War II Ghost Army team: 
Enigma Alberti is the nom de plume of a group of successful children's book authors whose first book was SPY ON HISTORY Mary Bowser and the Civil War Spy Ring. 

Scott Wegener is a self-taught artist perhaps best known for being co-creator and artist of Atomic Robo. 

Exciting, entertaining, and educational...this unique and clever book is all these things! Middle-grade readers will be captivated by the fascinating history of the Ghost Army and will have a blast deciphering puzzles and clues using the tools provided within the book.
