In only a few brief days, NASA’s Perseverance rover is slated to land on Mars Thursday (Feb. 18), and it is bringing 5 “hidden gems” together with it.
For many years, NASA has been following a convention known as “festooning,” including enjoyable extras to spacecraft and rovers heading to the cosmos. Pioneer 10 and 11, two spacecraft launched into house within the 1970s, included a plaque that depicted Earth’s location within the galaxy in addition to footage of a unadorned man and a unadorned lady. The picture was the brainchild of Carl Sagan, who needed any extraterrestrial life who would possibly discover the spacecraft to know who we’re and contact us.
One of many objects included on Perseverance pays homage to this historical past. A plate fastened to the rover makes use of the identical sort of stylish line artwork used on the Pioneer plaque, this time depicting Earth, the solar, and Mars, all joined by strains of Morse code studying “Discover as one.’ And that is simply one of many many “hidden gems” on NASA’s Perseverance rover.

10.9 million names
The identical plate containing nods to NASA’s Voyager and Pioneer plaques accommodates one other particular message: three microchips carrying 10,932,295 names from NASA’s “Ship Your Title To Mars” marketing campaign. This can be a custom for NASA’s Mars rovers; the company’s most up-to-date Mars rover Curiosity carried a microchip with 1.2 million names.
Additionally contained within the microchips are 155 essays from college students who made it to the finals of the house company’s rover-naming contest. That contest was won by Alex Mather, a seventh grader from Virginia.
A COVID-19 tribute
Additionally included on the rover is a tribute to the healthcare workers who’ve been combating the coronavirus pandemic right here on Earth. The rover launched in July 2020, only a few months after the virus hit the U.S.
The rover group needed to acknowledge the impression of the yr by which the rover launched, and particularly these individuals on the frontlines of the pandemic. So, the group affixed an aluminium plate on the rover’s left aspect exhibiting the caduceus — the picture of a serpent wound round a workers that’s used as a logo of drugs within the U.S. — holding up the Earth.
Mastcam-Z: “Are we alone?”
Though plates like these carrying the names and honoring healthcare employees are purely ornamental, a few of the hidden objects on Perseverance are each ornamental and useful. Certainly one of these is Mastcam-Z, a pair of zoomable cameras on the rover to seize colour panoramas of the Crimson Planet.
Mastcam-Z is absolutely useful as a digital camera, but it surely additionally holds an important message, NASA said in a statement: “Are we alone? We got here right here to search for indicators of life, and to gather samples of Mars for research on Earth. To those that comply with, we want a secure journey and the enjoyment of discovery.”
The phrases “pleasure of discovery” are additionally written across the message in quite a lot of languages, and Mastcam-Z follows within the footsteps of the Pioneer program with pictures of Earth’s adolescence varieties like cyanobacteria, a fern and a dinosaur. There are additionally line drawings of a person and lady, just like these on the Pioneer plaques.
SHERLOC
Followers of geocaching — a treasure-hunting sport by which individuals use GPS to cover and discover treasures — will get pleasure from figuring out that the rover group hid a particular coin made from helmet-visor materials on one of many devices. The NASA assertion known as it a geocache “extra distant than another.”
The coin is a part of the calibration goal for the SHERLOC (Scanning Liveable Environments with Raman & Luminescence for Organics & Chemical compounds) instrument and is etched with the deal with of its well-known narrative namesake (221b Baker Road in London).
SHERLOC can also be adorned with a slice of Martian meteorite and 4 different samples of spacesuit materials. Whereas it is cool to have a few of NASA’s spaceflight historical past on Mars, the house company additionally included the spacesuit materials to see the way it holds up on the Martian floor.
Mars meteorite
Lastly, the scientists who constructed Perseverance’s SuperCam added their very own slice of Martian meteorite. SuperCam is a laser placed on the rover to vaporize bits of the Martian floor so as to decide the composition. The precise little bit of meteorite scientists added to the instrument made a round-trip journey to the Worldwide Area Station earlier than it hitched a experience on Perseverance to Mars.
All of those enjoyable little knick-knacks and memorabilia will contact down on Mars on Feb. 18.
