CECIL’S SECRET IN “SPY IN THE DESERT” LIVE SHOW!!! 

the fact that there were almost 80 complete randos selected from the audience to be the spy and fuckin! cecil told them The Secret™ !!!

the “secret” is out in the live show’s recording and i know some of yous following haven’t caught up to wtnv in a long while but still care a lot about cecil and carlos, BUT also it’s still technically meant to be a “secret”, in the spirit of the show’s theme...

...sooooooooo only click the read more if you want to find out!!!

CECIL AND CARLOS ARE DADS!!! THEY HAVE A WEE SON NAMED ESTEBAN, HE’S A TODDLER NOW WHO’S LEARNED TO SPEAK SENTENCES AND CECIL IS SO PROUD!!! he and carlos agreed that there should be some things that should just stay between friends and family and not on the air, but cecil is so desparate to find the Spy due to them being the Best Secret Keeper so that he can gush about his son! and then purposefully let’s the spy get away before the secret police can reach them :’D

so! yeah!!! very good and wholesome and i’m so happy because i’ve always wanted them to become dads they’re just such good dads here they are the loving doting dads with a child at last!!! ;___; ❤

Junko and Darlina Thnorry

Junko and Darlina Thnorry are known as the “Curies of VX.” They were a married couple who shared a passion for science, and both were formidable scientists in their own right. Junko Thnorry was born January 23, 1895, and Darlina Eastman (sometimes written Estman) was born March 5, 1901. They married in July 1928. In 1935, Darlina’s health began to decline, and she died May 19, 1937. After her death, Junko continued to be active in the VX community, though this later work is widely considered to be inferior to their work together. Junko died January 24, 1986, at the age of ninety-one. He had never remarried.

Darlina kept various journals throughout her life, detailing events in her personal life as well as her scientific discoveries, questions, and theories. Of the greatest interest to most modern VXers are the carefully crafted diagrams of her VX setup, which were published in the General VX magazine, June 1985 edition. Her journals in their entirety were inherited by Eva Sturgeon-Thnorry, Junko’s niece, who donated them to the Chicago Radioscience Institute. They are available in the archives there, and have been copied for various libraries and institutes.

Published works by the Thnorrys include articles in various scientific journals (written both jointly and individually), 4 textbooks on bionucleation for Chicago State University (3 written jointly, 1 written by Junko after Darlina’s death), as well as a collection of short stories written by Junko, which never gained as much popularity as their scientific works.

The Thnorrys are most famous for their work in early biotech, and created the bioemulsifier DT-ermasmium which is still used today due to its unrivalled effectiveness. Their other creations and discoveries include radon-98 inhibitors, the crested jumble-regulating archnormalizer, and the New Theory of Dual Bionucleation.

132 grams to communicate with Mars

132 grams to communicate with Mars

On behalf of the ESA, UCLouvain has developed antennas for the LaRa instrument that will go to Mars in 2020 to study the red planet’s habitability. The originality of UCLouvain’s concept: the antennas are produced from a single block of aluminium to achieve lightness (132g!), miniaturisation (hand-sized) and great resistance (particularly to day-night temperature variations of more than 200° C). Credit: UCLouvain

Dust storms, ionising cosmic radiation, extreme cold at night … Mars is not very hospitable! It’s for these extreme conditions that the research team of Christophe Craeye, a professor at the UCLouvain Louvain School of Engineering, developed antennas for the ‘LaRa’ measuring instrument (Lander Radioscience ), which will go to Mars in 2020.

Prof. Craeye’s laboratory has been producing antennas for more than 15 years, for various uses: road radars, magnetic resonance imaging, tracking objects equipped with radiofrequency identification (RFID) chips. The goal is always the same: retrieve remotely data sent by a measuring instrument (of a vehicle’s speed, the body’s internal functions, an object’s or individual’s location, etc.).

For this expertise, as part of the ExoMars mission, the European Space Agency (ESA) contacted (via Antwerp Space) UCLouvain. The mission’s purpose is to study the rotation of Mars in order to learn more about the composition of its core and determine whether the planet was/will someday be habitable. How? By means of the LaRa instrument, which will communicate with Earth via radio waves. Thus the importance of antennas: they receive and emit radio waves. By measuring the Doppler effect—the difference between the frequencies of the waves emitted on the way (Earth-Mars) and those on the return (Mars-Earth)—the antennas will make it possible to better understand the movement of Mars and therefore the composition of its core. This is why LaRa is equipped with 100% UCLouvain-made antennas: a receiving antenna and two transmitting antennas (one of which is a backup).

Production requirements:

Resilience: Earth’s atmosphere protects us from the sun’s rays and limits temperature variations between day and night, which makes our planet habitable. Mars doesn’t have an atmosphere. Temperatures range from 80° C during the day (when the sun is most intense) to -125° C at night. Not to mention vibrations generated by dust storms.

Lightweight and miniaturised: the LaRa instrument will be equipped with multiple components, each for a specific use as part of the ExoMars research mission. Its total weight is distributed among its components, which must therefore be the smallest and lightest possible.

The UCLouvain team’s greatest feat: from concept to prototype, it created the antenna in a mere three months.

The advantages of UCLouvain’s design:

An innovative manufacturing process: antennas of unprecedented shape were created by milling from a single block of aluminium—no welding means increased resistance to vibration and temperature variations, in addition to being extremely lightweight. The receiving antennas weigh 132g maximum, the emitting antennas 162g maximum. And they fit in the palm of the hand. The design’s originality won over the ESA.

Exceptional sensitivity: the antennas are capable of capturing a radio signal from any direction, and focus it on the transponder’s electronics—an area of less than 1 cm² in the centre of the antenna—for the strongest possible signal.

What next? Applications are being developed in the field of satellite communications. And many industrial collaborations exist in fields beyond space and as varied as medical imaging, radio-frequency sensors, radar and telecommunications.

ESA’s Lander Radioscience experiment (LaRa) for ExoMars Mission 2020 has completed its testing in conditions similar to Mars and will be carried to Russia for its acceptance review, followed by integration onto the Kazachok Surface Platform.

At about 8 x 8 x 20 cm and a trio of antennas, LaRa is a high-operating transponder maintaining an extremely stable direct radio-frequency link between Earth and Mars for a full Martian year. LaRa has been planned by the Royal Observatory of Belgium, developed through ESA’s PRODEX programme and funded by the Belgian Space Policy Office.

The latest testing of LaRa was done in ESA’s Mechanical Systems Laboratory (MSL) at the Agency’s ESTEC technical heart in Noordwijk, the Netherlands. It is able to perform space simulation test, serving spacecrafts, mini-satellites, subsystems.

After vibration testing on an MSL shaker for simulating harsh launch conditions, atmosphere re-entry, landing on Mars, LaRa was placed inside a thermal vacuum chamber for functional testing in hot and cold conditions. At first, it was kept in high vacuum to outgas fumes which could pose problems in space. Then it faced simulated Martian conditions, with 6 millibars of carbon dioxide and varying temperature to test its performance. The electronic box of LaRa will be kept warm by the heater of ExoMars lander.

Developed in collaboration between ESA and Université Catholique de Louvain, the unique antenna will be installed outside the thermally controlled conditions to withstand extreme temperature as cold as -90°C and as hot as 10°C. Engineers advanced to remove sensors and cables fitted for testing after opening the thermal chamber before placing the instrument along with the antennas into sterile bags to avoid microbial infection.

Lieven Thomassen of LaRa prime contractor Antwerp Space said that the interior is made of four layers of circuit board which has been cleaned fully. It is completely sealed, with only 2mm diameter hole to avoid excess pressure in space.

LaRa is one of the two ESA instruments on the ExoMars Surface Platform. The first role of the platform is to make sure that itself and the Rosalind Franklin ExoMars rover, also made by ESA safely lands on the Oxia Planum lowlands in Mars. Then Kazachok will be running 13 experiment packages aboard. LaRa will be receiving X-band radio signal from Earth which will be relayed back again. By measuring the small Doppler shifts in this two-way signal, scientists will identify small periodic shifts in the position of Surface Platform as time passes.

Véronique Dehant of the Royal Observatory Belgium, the instrument’s principal investigator said that this will disclose information of planet’s internal structure, accurate calculation of its rotation and orientation and variation in angular momentum due to mass redistribution such as seasonal transfer of mass in carbon dioxide when a portion of the atmosphere freezes. The main challenge is to maintain the highly stable direct radio link in the planned operating schedule of LaRa, that is two sessions of an hour each per week, especially when Mars is at a maximum distance of 401 million km from Earth.

ESA microwave engineer Václav Valenta, manager of the LaRa project said that they will be using huge 70m antennas of Deep Space Network of NASA for transmitting X-band radio signal towards Mars and to pick up a delayed replica with as low as 5W of radio power generated by LaRa.

On Mars, LaRa will need enough sensitivity to detect very low radio signals. When Earth and Mars approach closer, the Estrack ground stations of Europe will close the link with LaRa. This was successfully tested in the radio frequency compatibility tests in ESOC mission control center in Darmstadt, Germany.

The atmosphere of Mars is a complicating factor. It enables convection for carrying away the waste heat. Though thinner than the atmosphere of Earth, radiofrequency operation leaves a risk of corona effects. Václav said that LaRa was formerly subjected to ESA’s High Power Radio Frequency Laboratory to remove corona risk which is ionization of local gases leading to adverse lightning-like discharge.

It also was tested inside the Maxwell chamber of ESTEC for electromagnetic compatibility to check that all the elements work properly. For verifying the robustness of LaRa against mechanical shocks due to the carrier module separation, a shock model was developed and tested at ESTEC Test Centre. After testing was completed, it was moved to ESA’s Metrology Laboratory for accurate measurements of its surface flatness for perfect fit and thermal contact with its lander interface to maintain a proper operational temperature.

After that, it will be moved to the Space Research Institute of the Russian Academy of Sciences, IKI for final approval testing followed by full assembly-level testing at Cannes in France. Václav said that the LaRa team worked very hard as actual developments for the flight model started a year late. ExoMars 2020 will be launched by the Russian Proton launcher from Baikonur, Kazakhstan on July 2020.
