ndia has landed its Chandrayaan-3 spacecraft on the moon, becoming only the fourth nation ever to accomplish such a feat. The mission could cement India’s status as a global superpower in space. Previously, only the United States, China and the former Soviet Union have completed soft landings on the lunar surface. Chandrayaan-3’s landing site is also closer to the moon’s south pole than any other spacecraft in history has ventured. The south pole region is considered an area of key scientific and strategic interest for spacefaring nations, as scientists believe the region to be home to water ice deposits. The water, frozen in shadowy craters, could be converted into rocket fuel or even drinking water for future crewed missions. Ex-NASA astronaut explains why the moon's south pole is of special interest 00:45 - Source: CNN Indian Prime Minister Narendra Modi, currently in South Africa for the BRICS Summit, watched the landing virtually and shared broadcasted remarks on the livestream. “On this joyous occasion…I would like to address all the people of the world,” he said. “India’s successful moon mission is not just India’s alone. This is a year in which the world is witnessing India’s G20 presidency. Our approach of one Earth, one family, one future is resonating across the globe.

Venomous snakes - The Amazon is home to at least 17 venomous snake species 26 August 2018 (20879 visits) In popular culture, books and films are filled with tales of deadly venomous snakes attacking humans. However, in the rainforests of the Amazon basin snakes are not aggressive, and will usually only bite a human when disturbed and fearing for their own safety. South America’s Amazon basin is home to at least seventeen species of highly venomous snakes, including seven species of pit viper and ten species of coral snake. The pit vipers of the Amazon include the bushmaster (Lachesis muta), which at more than 2.5 meters (8 feet) in length is the biggest venomous snake in the Americas. However, while this snake has gained a fearsome reputation, very few of the snakebites inflicted on humans have ever been attributed to this species, which tends to feed on small rodents. It is another pit viper, the more inoffensive looking one meter-long (3 feet) fer-de-lance (Bothrops atrox), common to tropical northern South America but only recorded in Peru around the northern Tumbes area, which is responsible for the greatest percentage of snakebites in South America, probably due to its habit of living in the vicinity of human settlements, rather than to any particularly aggressive tendencies. One of the venomous snakes found in Tambopata National Reserve is the so-called false fer-de-lance (Xenodon rabdocephalus), a rather nondescript brown snake with gray markings, which grows to around 80 centimeters (30 inches) in length. Species of coral snake also vary considerably in size, from the 50 centimeter (15 inch) pigmy black-backed coral snake (Micrurus scutiventris) to the 1.80 meter (6 feet) Amazon coral snake (Micrurus spixii). As their name suggests, coral snakes tend to be brightly colored. But, while in nature bright colors are usually a danger signal, indicating that the species in question is highly venomous (as in the case of many tropical snakes and frogs), the rainforests of the Amazon basin are also home to species known as false coral snakes, which are in fact completely harmless. However, it can be extremely difficult to distinguish between a coral snake and a false coral snake, and so caution is advised whenever a brightly-colored serpent is spotted on forest trails. Snakes use sophisticated detection systems in order to locate their prey. Their tongues are vital sensory organs, and they flick them repeatedly as they gather information about the terrain they are moving through. Species of pit vipers are known to employ thermo-receptors located in the facial pits that give them their name, producing infrared thermal images with which they identify their prey. According to researchers, a pit viper’s thermal imaging system is so sensitive it is able to detect the temperature variation caused by a small rodent 15 centimeters (6 inches) away. When venomous snakes strike, their venom is administered to the victim via hollow fangs that operate in the same way as hypodermic needles, the human invention that snake fangs inspired. Fascinatingly, members of the Amazon basin’s dangerous fer-de-lance genus have also contributed to humanity, through the discovery of the angiotensin converting enzyme (ACE) inhibitors that control blood pressure and thereby extend the lives of those suffering from hypertension.

Falcon Heavy is a partially reusable super heavy-lift launch vehicle[a] that can carry cargo into Earth orbit, and beyond. It is designed, manufactured and launched by American aerospace company SpaceX. The rocket consists of a center core on which two Falcon 9 boosters are attached, and a second stage on top of the center core.[8] Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System, and the fourth-highest capacity of any rocket to reach orbit, trailing behind the SLS, Energeia and the Saturn V.

After nearly two years, orbiter Atlantis is set to make her return to the International Space Station (ISS) in November following her extremely successful flagship mission (STS-125) to repair the Hubble Space Telescope in May 2009. However, meetings have been taking place on Wednesday to discuss the target launch date due to a number of constraints. STS-129 Evaluations: As part of this return to ISS construction/maintenance duty, Atlantis has been undergoing pre-mission processing for STS-129 in Orbiter Processing Facility Bay 1 (OPF-1) at the Kennedy Space Center ever since her return to the Florida spaceport on June 2 following STS-125’s landing in California in late-May. As of this week, engineers and technicians in OPF-1 – under the direction of veteran orbiter flow director Angie Brewer – are nearing the completion of their processing efforts on Atlantis.
