Thinking of traveling to space for common citizens seems nearly impossible. but with the advancement of space travel in the near future, we might be spending our vacations in space looking at the sun, moons, planets, and other celestial bodies. The concept of space tourism is one of the most exciting emerging features of human space travel. What is Space Tourism? Space Tourism simply means humans traveling into space for recreational purposes. it offers a paid tour to space by some commercial companies like Virgin Galactic and Blue Origin which are developing spacecraft to take paying travelers beyond the earth's surface. The first space tourist was US millionaire Dennis Tito, who in 2001 paid $20 million to hitch a ride on a Russian Soyuz spacecraft to visit the international space station and spent eight days there. space tourism covers spaceflights that are sub-orbital(reach lower space but are not powerful enough to enter Earth’s orbit), orbital(achieve orbital velocity ...

The photo or video sent using the feature will also expire from the chat if it's not opened within 14 days. Once you have updated the latest version then you will get the "View Once...
Scientists have said: A ceiling-mounted device has been developed which can detect whether individuals in the room have Covid-19 in 15 minutes. Researches from the London School of Hygiene & Tropical Medicine(LSHTM) and the biotech company RoboScientific with Durham University, study tested devices with Organic semiconductor sensors which could potentially be used as a Screening tool for Covid-19. They anticipate this sensor can be used in public spaces where the risk of transmitting the disease can be high. It has been founded in research that Covid-19 infection has its own distinct smell. These odor results from changes in VOC compound which make body odor that the sensor can detect. A team of 54 individuals donated their body odor sample of work socks - 27 covid-19 positives who asymptotic or had mild symptoms and 27 individuals were uninfected. Samples were analyzed by the developed sensor Roboscientifc’s Model 307B VOC analyzer fitted with an array of 12 OSC sensors. on the fi...
