Autonomous helicopter joins its rover buddy for Mars 2020 mission NASA has a bold plan to send not only a rover but also a helicopter to Mars as part of its Mars 2020 mission. The autonomous Mars Helicopter, which NASA hopes will be the first aircraft to fly on another planet, successfully passed its flight tests and vacuum and deployment tests. Now, the helicopter has been attached to the Mars 2020 rover ready for its journey to the red planet. The rover was secured onto a plate on the rover’s belly and covered by a shield to protect the delicate machine from rocks and other debris which will be kicked up during entry and landing on Mars. Once the craft has landed safely, the helicopter will emerge from behind its shield and be sent into the sky to explore the Jezero Crater region around the landing zone. As the helicopter is a highly experimental piece of equipment, the engineers won’t be relying on it to collect any important scientific data. Instead, the Mars mission will act as a real-world test for the reliability of the helicopter, so NASA can see if it can move around the planet despite the thin atmosphere. If it’s successful, engineers can use what they learn to create next-generation helicopters for future missions. “Our job is to prove that autonomous, controlled flight can be executed in the extremely thin Martian atmosphere,” MiMi Aung, the Mars Helicopter project manager at NASA’s Jet Propulsion Laboratory, said in a statement. “Since our helicopter is designed as a flight test of experimental technology, it carries no science instruments. But if we prove powered flight on Mars can work, we look forward to the day when Mars helicopters can play an important role in future explorations of the Red Planet.” The primary advantage of having a helicopter as well as a rover is that an airborne craft can explore locations that would be impossible to reach from the ground. This includes maneuvering around geographical features like cliffs, chasms, and caves to get a more detailed view of the Martian environment. In the future, helicopters could also carry scientific equipment to gather data from distant locations, or they could be used as scouts for investigating a region ahead of human or robot explorers. For now, we’ll have to wait and see how the first helicopter for an extraterrestrial environment fares on its inaugural mission. The launch of the Mars 2020 mission is scheduled for July next year.

NASA šalje helikopter na Mars NASA šalje helikopter na Mars u sklopu sljedeće misije istraživanja Crvenog planeta. Let helikoptera imena Mars zakazan je za srpanj 2020. godine i demonstrirat će održivost i potencijal lebdećeg vozila na Crvenom planetu. "NASA ima ponosnu povijest. Ideja helikoptera na drugom planetu je uzbudljiva. Helikopter Mars ulijeva nam puno nade u našu znanost u budućnosti, za otkrivanje i istraživanje misija na Marsu", rekao je administrator u NASA-i Jim Bridenstine. Projekt helikoptera Mars započeo je u kolovozu 2013. kao projekt razvoja tehnologije u NASA-inom laboratoriju. Rezultat gotovo petogodišnjeg dizajniranja je vozilo teško tek 1,8 kilograma s trupom veličine loptice za softball. S dvostrukim rotirajućim elisama, helikopter Mars imat će gotovo 3000 okretaja u minuti što je oko deset puta više od brzine okretaja elisa helikoptera na Zemlji. Također, helikopter sadrži solarne ćelije za punjenje litij-ionskih baterija i mehanizam grijanja kako bi bio topao tijekom hladnih noći na Marsu. "Prikladno je da su Sjedinjene Američke države prva nacija u povijesti koja će poslati helikopter na Mars. Ovo uzbudljivo i vizionarsko postignuće potaknut će mladež diljem SAD-a da postanu znanstvenici i inženjeri", rekao je republikanski kongresnik John Culberson. index.hr Mišljenje Vrijeme u Mostaru - Vedro - Temperature: 1°C
