On Tuesday, July 20, 2021, the founder of Amazon, @JeffBezos, is all set to fly to the edge of space along with three others, aboard his company @blueorigin's New Shepard rocket.
Surpassing the #troposphere and #stratosphere, the space flights of @blueorigin will fly to the edge of space, about 100 km above the Earth’s mean sea level—the Karman line, also called the ‘edge of space’.
The spaceflight that @virgingalactic's founder Richard Branson took as part of #Unity22 on July 11 did not go beyond the Karman Line.
Comparing spaceflight capabilities of Virgin Galactic and Blue Origin
Most @virgingalactic spacecraft has a jet-powered aircraft docked underneath. The carrier aircraft takes off from a runway and climbs to an altitude of more than 40,000 feet.
Then the spacecraft is dropped, free-falling briefly before firing its rocket motor and ascending to about 295,000 feet, or roughly 90 kilometres, which is 10 kilometres short of the Karman line.
.@blueorigin's rocket-and-capsule combo, called the #NewShepard, shoots into suborbital space and then separates its components. The pressurised capsule floats in microgravity for a while before falling back to Earth assisted by a parachute system.
This domed capsule boasts six observation windows一the largest ever used in a space travel vestibule. The 60-foot tall rocket section returns to the launchpad, and the company can reuse this booster rocket for future launches.
The #VirginGalactic space-planes can accommodate 4 passengers, with 2 additional crew members. On the other hand, the #BlueOrigin rockets are designed for 10-minute fully autonomous flights, with at most 6 passengers on board.
.@SpaceX has already entered the orbital tourism arena一a feat restricted to government-funded agencies for more than half a century一taking crew and passengers up to 400 kilometres above the Earth’s surface.
The @SpaceX launch system uses a larger capsule and more powerful rocket compared to the @blueorigin combo.
Its ‘Dragon’ capsule can carry more passengers than the others一7 at the moment一and a 230-foot tall rocket booster called #FalconRocket, which it uses to reach the Earth’s orbit and make trips around the #Earth.
The @SpaceX trips also last longer than the other private space travel options, with trips lasting about 3-4 days from launch to splashdown.
.@SpaceX is currently working on building a starship capable of carrying cargo with up to 100 passengers at a time to outer space. #SpaceX's charter flights will soon begin missions to the #Moon, and eventually to #Mars.

#China's central Henan province received its heaviest rainfall in 1,000 years—Zhengzhou saw 624 mm of rainfall on Tuesday, with a third of that amount falling between 16:00 and 17:00 alone.
The death toll from torrential rains in central #China's Henan province increased to 33 on Thursday, while eight people still remain missing and more than 30 lakh others affected, local authorities confirmed.
A total of 3,76,000 local residents have been relocated, said the provincial emergency management department.
Rainwater has damaged more than 215,200 hectares of crops, causing a direct economic loss of about 1.22 billion yuan ($188 million), reports Xinhua news agency.
A second flood warning in southern districts of #TamilNadu, including Madurai district is expected following incessant rains increasing the water levels in the #VaigaiDam.
A statement from the state water resources minister's office said that the department will issue the second flood alert only if the water level in #Vaigai touches 68.5 ft.
The torrential downpour in #Mumbai in the past four days had an unexpected fallout - around 100 students missed the annual IPMAT entrance exams to get admission to #IIMIndore.
The affected students are now running from pillar to post, with frantic messages to #IIMIndore Director, Professor Himanshu Rai, and even Union Education Minister Dharmendra Pradhan.
Photographer Chris Mathews shot a once-in-a-lifetime image earlier this year. Mathews was able to capture the aurora borealis in all its colourful glory over the erupting Geldingadalur volcano in #Iceland.
"The volcano is located on the Reykjanes Peninsula in southwest Iceland, close to the international airport and not far from where I live," Mathews said.
Now, in a stunning capture, ocean scientists have recorded video footage of a creature that would put even the most deceitful of creatures to shame: an almost-invisible, eight-legged glass octopus!
This elusive organism, similar to glass frogs or comb jellies, is completely transparent. The only features that can be seen are its cylindrical eyes, optic nerve, and digestive tract.
