In a study published on Monday in the journal Circulation , scientists reported that the largest chamber of the heart of Scott Kelly, who spent nearly a year on the International Space Station in 2015 and 2016, shrank in mass by more than one-quarter by the time he returned to Earth.
That just adds to the litany of transformations that the human body undergoes without the steady downward pull of gravity. Astronauts also tend to have swelled heads, squashed eyeballs, shriveled legs and bones that become more brittle.
This may worth something:
Promise Of Private Space Travel Coming Closer To Reality – CBS Miami
CAPE CANAVERAL (CBSMiami) – The promise of private space travel is coming closer to reality thanks to some well-known billionaires. One company is selling seats for a new craft that could take passengers above the Earth next year, while another company is trying to get to Mars.
Virgin Galactic believes the VSS Imagine spacecraft will give paying customers a chance to be an astronaut.
"It’s tremendously exciting. It’s been a long, a long journey to get this far,” says Sir Richard Branson, founder of the Virgin Group.
The future of space tourism: op-ed | Space
Dylan Taylor is a global entrepreneur, investor and philanthropist who acts as the Chairman and CEO of Voyager Space Holdings and the founder of Space for Humanity , a nonprofit organization that seeks to democratize space exploration.
It's true that 2020 spawned a collective feeling of retreat coupled with a FOMO (fear of missing out) that inspires us to escape a chaotic world. For now, we have the silence of nature or an eventual trip abroad, but the future can provide a more adventurous escape: one to the stars.
A Change of Heart: Astronaut's Heart Shrank From Space Travel Even After Regular Exercise, Study
This result was based on the examination of retired astronaut Scott Kelly, who lost an average of 0.74 grams per week in the mass of his heart's left ventricle during the 340 days he spent in space, from March 27, 2015 to March 1, 2016. This loss occurred despite a weekly exercise regimen consisting of cycling, treadmill, and resistance exercise.
These findings are comparable to the reports of a long-distance swimmer who spent nearly half a year trying to cross the Pacific Ocean.
Many things have been taking place:
4 Stocks to Bet on as Space Travel Gains Prominence
Last year, the National Aeronautics and Space Administration (“NASA”) sent astronauts to the International Space Station (“ISS”) for the first time since 2011. Also, private companies like SpaceX launched a record-breaking 26 space missions, an endeavor to test flights for commercializing Earth’s lower orbital programs and delivering packages to the ISS. Virgin Galactic Holdings, Inc.
Why will the momentum continue in 2021? Firstly, satellite imaging market is booming as the demand for landscape and terrain data for autonomous vehicles has witnessed drastic growth, thanks to the advancement of the self-driving era. Additionally, communication companies are putting in millions of dollars to provide high-speed connectivity in remote locations across the globe. The Biden administration is also lending support to the space economy’s growth.

"We're interested in exploring the universe, and there's really interesting people doing that," said Coleman at the podcast's launch event. "Something we made clear to our guests is that we are here to talk about what you want to talk about. Because there are some really big questions about exploring the universe, about what it means to be an interplanetary species."

SpaceX Starship SN11 rocket fails to land safely after test launch in Texas: SpaceX | Reuters
(Reuters) - An uncrewed SpaceX Starship prototype rocket failed to land safely on Tuesday after a test launch from Boca Chica, Texas, and engineers were investigating, SpaceX said.
"We do appear to have lost all the data from the vehicle," SpaceX engineer John Insprucker said in a webcast video of the rocket's flight test. "We're going to have to find out from the team what happened."
The webcast view was obscured by fog, making it difficult to see the vehicle's landing. Debris from the spacecraft was found scattered five miles (eight km) away from its landing site.
