The impact of space travel on the body

Over the past decades, space exploration has encountered significant breakthroughs from the discovery of new planets, new constituents in different worlds, a successful launch of the first person on the moon, and the development of various objects in the universe. Currently, the space industry seeks to explore other parts of the world and launch the first person on Mars. The plan is to first establish a base on the moon by which the spacecraft inhabiting the crew members can refuel before setting to Mars. NASA plans to launch its first crew members by 2025 to the moon and establish a base by which Mars explorations can then follow. However, a recent study showed that launching people into space can have dire effects on their body, which entails the brain and genetic makeup. 

Since the launch of humans to space, NASA researchers have monitored the health of the astronauts and the effect space explorations continuously has on their bodies. The famous Twin Study results displayed that indeed launching humans to space alters their normal body function and also their genetic makeup. Nevertheless, recent research showed that space exploration affects brain function. 

The brain is the control system of the body, and it translates and distributes information to the rest of the body, causing either voluntary or involuntary movements. The research conducted displayed that the brain is affected during space flights that resultantly causes impaired eyesight. The study is backed up by medical complaints submitted by astronauts as they arrived back on Earth. Likewise, the majority of the spacemen complained about the issue of impaired eyesight since the launch of space travel in the shuttle program. According to the medical results, spacemen experience swelling in the optic nerves, and others encounter retinal hemorrhage. Also, some astronauts experience a structural conformation on their eyes. 

According to a radiologist Larry Kramer, the optical defects are caused by a difference in intracranial pressure during the launch of the spacecraft, which consequently creates increased microgravity. The study initially took MRI scans of eleven astronauts before and after space travel, and the results were storming. Indeed, continuous exposure of microgravity causes swelling in the brain that results in an increased level of cerebrospinal fluid. The research, therefore, is in-line with the fundamental theory that space travel affects the brain cells. Also, Kramer noted that continuous exposure to microgravity caused compression in the pituitary gland, which links the problem to a brain malfunction. Also, after a year out of space travel, the effects of impaired eyesight decreased the pituitary gland, and swelled brain cells were still present hence confirming that the impact had a long-term result. 


Stratolaunch has plans to launch hypersonic vehicles using the largest plane in the world

 The largest airplane in the world ever built has found another use, according to Stratolaunch. Stratolaunch company founder is Paul Allen in 2001, who is also a co-founder of Microsoft. The original plan for the airplane was to launch a satellite with a wingspan of 117 meters. In 2018 October, Allen died, and later the company management sold it, which raised many questions about the future of the company. 

This year, most of the questions have answers. According to the information available to the company website, it has re-established itself and now is one of the builders’ operators and testers of the hypersonic vehicles. The vehicle can travel faster than the sound of sound or the speed of Mach 5. 

Stratolaunch CEO Floyd W. Jean, on his statement on the website of the company, said that the hypersonic testbeds they build would be the catalyst for sparking rebirth in the technology used in Hypersonic for our government and both commercial and academia sectors.

The plan is the main thing in the new mission, vehicle hauling the test of different payloads aloft in the dangerous environments that will occur on the hypersonic flight. The stratolaunch Talon-A will be among the vehicles in the mission, which is 8.5m long and weighs 2,722 kilograms. THE aircraft is reusable and can reach Mach 6.

Talon-A primary function is to conduct flights with long-duration at high Mach, and then it will come back for an autonomous. It will land horizontally on the runway that it conventional, which the company refers to it as the description of the craft condition. The other ability of the vehicle is the autonomous ability with its power through the conventional runway.

This large dual-fuselage spacecraft formerly it was Roc, but the name changed to stratolaunch. It will have the ability to drag three Talons-As one at a time. It will give the people a lot of time to gather the data, and the information is according to the representatives of the company. The end of the envisioned road is not Talon-A, but the company is developing Talon-Z. It gave little information on its website about talon-Z and the other exciting type of vehicle referred to as Black Ice. Black Ice will fly some interesting and most ambitious missions if the planned schedule remains according to Stratolaunch. Also, black ice is a reusable plane that carries cargo and the crew to the orbit of the moon and back.


Third Starship prototype get stacked by SpaceX before testing begins

The newest Starship prototype of SpaceX is standing tall. The latest trial version of the Mars-colonizing starship spacecraft, known as the SN3, has been set at the South Texas facilities of SpaceX, new pictures cheeped out by firm CEO and founder Elon Musk show. Musk posted dual pictures on twitter early Thursday morning, March 26.  The principal shows the tank of SN3 and engine parts sitting side by side in the assembly ability, and the next shows them joined. Musk did not offer more in the method of context; he just wrote simply SN3.  SN3 stands for serial number three. The prototype is the third repetition of the newest starship design.

Achievement of the stacking milestone proposes that SpaceX that has been going quickly around the starship project will start testing the auto soon.  This type of testing will begin with pressure tests that have chopped new starship prototypes. Though when the sn3 makes it complete by that gauntlet, the prototype will spread its wing immediately. 

Musk says that his goals are to conduct short flights in the atmosphere of the Earth with the SN3, then hover longer and higher trial missions with the serial number four (SN4). Starship launches atop big rocket known as super heavy that will have room for 37 of next-generation raptor apparatuses of SpaceX. All essentials will be rapidly and thoroughly reusable; the big rocket will be back to the universe for vertical landings presently after giving starship to orbit, and the craft for space will do a similar job when it completes its work.

Some work takes the starship far away from the field when all goals for Musk are at pa. The rocket will have the ability to carry one hundred individuals to distant destinations like the mars and the moon, Musk said. And the ultimate plan is the red planet. He needs the architecture of starship to assist humanity come up with many personal cities on Mars in the coming 50 to 100 years.  

The last craft of the space will identify its raptors that will offer sufficient power to lift off those bodies of planetary. The world is so more prominent than the mars or moon and thus has more gravitational force. We could see Super heavy and starship flying operational missions as soon as possible when development and testing go well. The representatives of SpaceX say that the system could start hurling satellites to Earth orbit next year.
