The Mars Helicopter aims to make the first powered flight on another planet when it takes off on Mars as part of the Mars 2020 mission. I learned a lot getting to visit the drone right before it was mounted on the rover.
How do you fly in 1% of Earths atmosphere:
Have large rotors (they are 1.2m in diameter) and spin them very fast, around 2500 RPM (5x the speed of a helicopter on Earth).
Plus the aircraft has to be light:
The Mars helicopter weighs in at 1.8kg or around the same as a laptop. Every piece had to be stripped down for weight. Instead of using aerogel for insulation, the craft makes use of CO2 gaps between components. Even aerogel was too heavy!
One of the major challenges is surviving the Martian night:
Temperatures plunge to -80C to -100C so two thirds of the crafts power is actually used to keep its electronics warm. Only one third is used for flying. The estimated flight time is 90 seconds.
The craft cant be driven remotely, it will have to fly autonomously, using its own sensor suite to determine how to fly. The round trip 20 minute delay with Earth means steering the craft from mission control would be impossible.

Another cool video of DFKI space robots in the desert of morocco: youtu.be/-zqve9baOzM
A barren, rocky desert landscape and not a single soul around – to come as close as possible to the inhospitable conditions on the Red Planet, scientists of the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) tested the cooperation of various robot systems in the desert of the American state of Utah from 24 October to 18 November 2016.
The project Field Trials Utah (FT-Utah) is funded by the German Space Agency (DLR Agentur) with federal funds of the Federal Ministry of Economics and Technology in accordance with the parliamentary resolution of the German Parliament, grant no. 50 RA 1621 (DFKI) and 50RA1622 (University of Bremen).
The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A 2.4-meter (7.9 ft) aperture telescope in low Earth orbit, Hubbles four main instruments observe in the near ultraviolet, visible, and near infrared spectra. The telescope is named after the astronomer Edwin Hubble.
Hubbles orbit outside the distortion of Earths atmosphere allows it to take extremely high-resolution images with almost no background light. Hubbles Deep Field has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.
Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. The HST is one of NASAs Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, Hubbles main mirror was found to have been ground incorrectly, compromising the telescopes capabilities. The optics were corrected to their intended quality by a servicing mission in 1993.
Hubble is the only telescope designed to be serviced in space by astronauts. Between 1993 and 2002, four Space Shuttle missions repaired, upgraded, and replaced systems on the telescope; a fifth mission was canceled on safety grounds following the Columbia disaster. However, after spirited public discussion, NASA administrator Mike Griffin approved one final servicing mission, completed in 2009. The telescope is now expected to function until at least 2014, and possibly 2020. Its scientific successor, the James Webb Space Telescope (JWST), is currently scheduled to be launched in 2018.
Hope you enjoyed it as mush as i did making it!

Откуда на теле её подопечного Николая каждое утро появляется новый кровоподтёк от инъекции, которой нет в предписании врача? Как предыдущая сиделка уехала в родной город без паспорта? И что за странный жилец обитает в гостевом домике? Обсудить свои догадки тоже не получается – все обитатели усадьбы хранят молчание. Вскоре из озера вылавливают тело молодой девушки, и в дом приезжает полиция…

Москва. Наши дни. В центре города из машины двое воришек крадут сумку с миллионом евро, думая, что им, наконец, повезло, и даже не представляя, во что на самом деле они ввязались. За деньгами начинается настоящая охота. Перед искушением не может устоять никто. Сумма в виде двух пачек денег по полмиллиона евро делает абсолютно разных людей одинаковыми в своих поступках и желаниях. А началось все с того, что «миллионщик» Григорий не захотел честно платить налог

Ещё до перестройки в СССР существовала специальная лаборатория при Институте информационных технологий, где изучали экстрасенсорные способности людей, пытаясь объяснить их с научной точки зрения. Именно там впервые встречаются Николай Арбенин и Виктор Ставицкий. Их противостояние, начавшееся, как борьба двух мужчин за сердце женщины, с годами перерастает в настоящую «битву экстрасенсов» — только проходит она не на телеэкране, а в реальной жизни.
Конец 1988 — начало 1989 годов: время, когда экстрасенсы собирали полные залы; выступали в прямом эфире по радио и центральным телеканалам. Время, когда противостояние Николая Арбенина и Виктора Ставицкого достигает своей кульминации.
