about the problem of Space Debris in orbit around the Earth, in view of the new <a href="https://www.gov.uk/government/news/citizen-scientists-look-to-the-skies-to-help-dstl-study" target="_blank" rel="noopener">UK Space Object Catalogue initiative</a>.</p><p>With space becoming more and more easily accessible over the last 3 or 4 decades, the number of objects in orbit, including uncontrolled objects like defunct satellites and debris from launch vehicles and collisions, has increased at an alarming rate. <a href="https://www.nasa.gov/mission_pages/station/news/orbital_debris.html" target="_blank" rel="noopener">Today it is estimated</a> that in orbit around the Earth are over 20,000 pieces of debris larger than an apple, over 500,000 larger than a pea and over 100,000,000 fragments smaller than 1 cm.</p><p>Travelling in excess of 28,000 kilometres per hour (that’s 8km/sec), even the smallest piece of debris can cause very serious damage to spacecraft, space installations, and is ultimately a lethal danger for astronauts working outside a space station. As an illustration, at this speed an object of 1cm has <a href="http://www.esa.int/spaceinvideos/Videos/2017/04/Dealing_with_space_debris" target="_blank" rel="noopener">the same destructive effect as a grenade</a>, and a 1 mm flake of paint creates an impact equivalent to that of a <a href="https://en.wikipedia.org/wiki/P%C3%A9tanque" target="_blank" rel="noopener">1.5 kg pétanque boule</a> thrown at a speed of 100 km/h.</p><p>With currently no efficient way of removing debris the situation continues only to get worse; debris orbiting around the Earth for years – even for several hundreds of years for the highest orbits – are going to fragment and multiply as they incessantly inter-collide with each other (the <a href="http://www.esa.int/Our_Activities/Space_Engineering_Technology/The_Kessler_Effect_and_how_to_stop_it" target="_blank" rel="noopener">‘Kessler Effect’</a>), rendering space potentially unusable as we lock ourselves inside a debris belt of our own creation.</p><p><a href="http://www.esa.int/Our_Activities/Operations/Latest_report_on_space_junk" target="_blank" rel="noopener">Identification and long term tracking of space objects</a> is essential to help future <a href="https://magazine.engr.utexas.edu/2018/in-their-own-words-moriba-jah/">space traffic policies</a> and avoid collisions with functioning structures in space (satellites, space station, …).</p><p>Unfortunately, current technology and data analysis techniques can only <a href="https://www.nature.com/articles/d41586-018-06170-1" target="_blank" rel="noopener">reliably identify and track objects above 10cm in size</a>, ( only 0.02% of dangerous debris ), highlighting also the crucial need for scientific advancement in this domain.</p><h2>Your Mission</h2><p>You have been assigned the perilous task of launching a new satellite into orbit around the Earth. However, as we have seen, this task is complicated by the fact that past irresponsible launch activities have left the target orbits cluttered with uncontrolled satellites and other debris.</p><p>You need to read the information (data) provided by the ground-based observatories on your screen to determine when it is safe to launch.</p><p>At each of the 2 launch stages you will be presented with 3 simultaneous sets of data from which you will decide the right moment for the launch.</p><p>For the first stage to activate the launch, click on “Launch to Orbit”</p><p>For the second stage click on “Launch to Second Orbit”</p><p>If you chose the wrong moment for either phase of the launch, the craft will be hit by orbital debris and destroyed, creating even more debris !</p><p>The game is tailored to your name, so you may also want to enter other names or words to play different versions of the game. You can move your view of the Earth using the mouse.</p> </div> </div> <h4 class="has-text-align-center wp-block-heading" id="start-your-mission-by-entering-your-name"> Start your mission by entering your name </h4> <div class="wrapper"> <div class="container games-single"> <div class="games-widget "> <div class="item"> <h3 class="use-desktop">Please use a laptop/desktop computer to play our game</h3> <iframe scrolling="no" width="100%" height="459 " src="/wp-content/uploads/games/spacedebris"></iframe> <div class="challenge"> <h3>Share with a friend</h3> </div> <div class="defaultShareWrap"> <span class='st_facebook_large' displayText='Facebook'></span> <span class='st_twitter_large' displayText='Tweet'></span> <span class='st_linkedin_large' displayText='LinkedIn'></span> <span class='st_pinterest_large' displayText='Pinterest'></span> <span class='st_email_large' displayText='Email'></span> <span class='st_sharethis_large' displayText='ShareThis'></span> <script type="text/javascript">var switchTo5x=true;</script> <script type="text/javascript" id="st_insights_js" src="https://ws.sharethis.com/button/buttons.js?publisher=f14ca852-318b-43e4-98a3-0988061a53ec"></script> <script type="text/javascript">stLight.options({publisher: "f14ca852-318b-43e4-98a3-0988061a53ec", doNotHash: false, doNotCopy: false, hashAddressBar: false});</script> </div> <div class="buttonGroup white"> <div class="buttons normal"> <button class="button red"><a href="/games">+ <span class="text">More Games</span></a></button> </div> </div> </div> </div> </div> </div> </div> </main></div> <div class="footerWrap"> <footer role="contentinfo"> <div class="container first"> <div class="container"> </div> </div> <hr> <div class="container second"> <div> <img class="footer-logo" src="https://www.thinktankmaths.com/wp-content/themes/chop-child/images/footer-logo.jpg" alt="Think Tank Maths" > </div> <div class="second-row"> <a class="linkedIn" target="_blank" href="https://www.linkedin.com/company/thinktank-maths-ltd./"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M4.98 3.5c0 1.381-1.11 2.5-2.48 2.5s-2.48-1.119-2.48-2.5c0-1.38 1.11-2.5 2.48-2.5s2.48 1.12 2.48 2.5zm.02 4.5h-5v16h5v-16zm7.982 0h-4.968v16h4.969v-8.399c0-4.67 6.029-5.052 6.029 0v8.399h4.988v-10.131c0-7.88-8.922-7.593-11.018-3.714v-2.155z"/></svg> </a> <a href="/privacy-policy/">Cookies Privacy Policy</a> <a href="/recruitment-privacy-policy">Recruitment Privacy Policy</a> <a href="mailto:general@ThinkTankMaths.com" class="email">general@ThinkTankMaths.com</a> </div> <div> <p class="address">ThinkTank Maths Limited<br> Hopetoun Gate 8b McDonald Road<br> Edinburgh EH7 4LZ<br> <a href="tel:+44 0131 467 5244">+44 (0) 131 467 5244</a><br> VAT NO.
