Reusable Chinese Space Craft Lands Returns Earth

The Chinese government has announced the safe return of a reusable spacecraft, called Chongfu Shiyong Shiyan Hangtian Qi (CSSHQ), to Earth, after spending two days in orbit. 

The unmanned spacecraft was launched on Friday, September 4th, 2020, from the Jiuquan Satelite Launch Center in northwest China’s section of the Gobi Desert, before safely returning to its scheduled landing site. The spacecraft’s purpose was reportedly to test reusable technologies that will provide ‘technological support for the peaceful use of space’, although no information about what technologies were tested has been made public. 

Adding to this, no pictures nor information of the spacecraft itself have been released into the press either, although the Chinese government did say that it was launched via a Long March-2F carrier rocket. This makes CSSHQ the 14th mission for the rocket, also used by the Chinese to send astronauts into orbit, as well as its own space laboratory.

The launch comes after earlier reports in which China said it planned to construct reusable Earth-to-orbit vehicles that would take off and land like airplanes. It also comes after reports from the China Aerospace Science and Industry Corporation stating that they had completed several ground tests for engines and other components for such a vehicle back in 2017. 

Considering the high costs of a single rocket launch, reusable parts- and indeed spacecraft- may be able to greatly reduce the cost of space flight and launching objects into orbit. As such, CSSHQ’s success marks a great milestone in China’s space program. 

Despite this, however, the reusability of parts from spacecraft doesn’t necessarily end up costing less in the long run. An example of this is NASA’s Space Shuttle. Although a partially reusable launch vehicle, it did not make the launch process itself any cheaper than disposable alternatives.

► Friends join Sara Ali Khan for a weekend of partying

After spending her birthday month in a pool house, Sara Ali Khan seems to be in no mood to return. She has invited her friends over to the beach destination for a staycation. Sharing a pic of herself floating around in the pool, Sara quipped, “Gulab in Gulabi on Gulabo”. Despite being surrounded by friends, she chose to stick to reading historical non-fiction The Square and the Tower, even with heart-shaped glares on. Must be quite a page-turner, no?

Ali Fazal may have to wait till next year to marry actress-girlfriend Richa Chadha but that won’t stop him from professing his love for her on social media. But, instead of sharing a loved up pic, Ali shared one of his ladylove mooning over Denzel Washington and wrote this was why he had a problem with him. “I mean ay Denzel, I love you but ahem!!! Richa Chadha bas bhi kijiye…” Fans thought Ali being possessive was sweet, but wonder what Richa thought of it.

Smoke traveling from western wildfires spreads bad air quality across the US

Devastating wildfires across the Western United States has sent smoke traveling across the country and even into Europe. With that smoke comes bad air quality, not just for those near the fires, but for the entire continent.

Satelite images from NASA shows smoke thousands of miles from the fire. NASA says the smoke contains aerosols, a combination of particles which carry harmful things into the air and into your lungs. All the things that are burning, trees, grass, brush, homes, are turned into soot and absorbed by our lungs.

“This pollution, nobody knows how badly it will be affected but if we extrapolate from previous air quality it’s not good,” Dr. Malik Baz, the medical director at the Baz Allergy and Sius Center, said. “The long-term side effect, we’ll see many, many years down the line.”

Baz’s operates 13 locations in California, all of them are busy as Central California is essentially a big bowl surrounded by mountains which trap pollution over the valley. Air quality is always an issue for this part of the state and fires multiply the problem.

“People with respiratory, allergy, asthma, ,sinus problem, anytime the air quality goes bad, their symptoms get worse,” Baz said. “It affects them but this air quality, it doesn’t matter whether you have respiratory problems or not, everyone is affected.”

It’s bad in other western cities too.

“This is really an unprecedented wildfire season in 2020,” said Jon Klassen, director of air quality science and planning for San Joaquin Valley Air Pollution Control District. “We have fires across most of the states in the western US, Washington, Oregon, California, Seattle. Portland has some of the worst air quality in the world right now, which is shocking because normally they have pretty good air quality.”

Klassen’s job is to monitor and

SpaceX launches Earth-observation satellite for Argentina, nails rocket landing

CAPE CANAVERAL, Fla. — SpaceX successfully launched an Earth-observation satellite for Argentina along with two small piggyback satellites today (Aug. 30).

A SpaceX Falcon 9 rocket carrying the SAOCOM 1B Earth-observation radar satellite for Argentina and two small rideshare payloads launches into orbit from Cape Canaveral Air Force Station in Florida on Aug. 30, 2020.

The trio blasted off from Space Launch Complex 40 here at Cape Canaveral Air Force Station at 7:18 p.m. EDT (2318 GMT). 

A used two-stage Falcon 9 rocket carried the SAOCOM-1B satellite aloft, marking the company’s 15th launch of 2020. Approximately nine minutes after liftoff, the booster’s first stage produced some dramatic sonic booms as it made its way back to terra firma, touching down at SpaceX’s Landing Zone-1 (LZ-1) at Cape Canaveral.

Today’s flight was the fourth launch for this particular Falcon 9 first stage. The booster, designated B1059, previously lofted two commercial cargo missions to the International Space Station for NASA and delivered a batch of SpaceX Starlink satellites into orbit earlier this year.

The Falcon 9 appeared to launch straight up as it climbed to orbit. The skies above the space coast were cloudy but you could hear the Falcon 9 long after it was out of sight. 

Thick clouds made it hard to track the first stage on its downward trek. Suddenly it appeared in the sky, with the iconic sonic booms you expect cracking overhead as the booster descended to the landing site. 

SAOCOM-1B deployed from the Falcon 9’s upper stage as planned 14 minutes after liftoff. The two rideshare satellites, GNOMES-1 and Tyvak-0172, were scheduled to deploy about an hour after launch.
