Before Mars, astronauts should swing towards Venus, experts believe



NASA plans to send manned missions to Mars in the 2030s, but before astronauts get there, they should stop by Venus first.

These are the sentiments expressed in a new article written by a number of researchers, who believe that going to the second planet in the Solar System can have benefits for a manned mission to the Red Planet. These include reducing the “overall energy requirements for opposition class missions to Mars”, with the added benefit of cutting costs, as well as going to a second planet.

“A human Venus flyby is not just a” free “add-on, but a beneficial addition to any mission-class Mars architecture of the opposite class,”

; the researchers wrote in the document. “As a result, if NASA’s first mission to Mars is an opposition class mission, it is likely that this mission will also include a Venus flyby.”

VENUS HAS BEEN HABITABLE FOR 3B YEARS. THEN SOMETHING HAPPENED HAPPENED.

They continued: “There is reason to be excited about this” two planets for the price of one-plus “approach. A one-year mission to Venus could serve as a valuable” shock cruise “for deep space transport needed for the first human mission to Mars. “

The researchers come from various organizations and universities, including Johns Hopkins University, NASA JPL and the Southwest Research Institute, which manages NASA New Horizons missions.

Not only are there potential economic benefits to using Venus’ gravity for missions to Mars, it could also be done on a more regular basis, the researchers added.

“Venus, on average, is much closer to Earth (1.12 UA) than to Mars (1.69 UA), allows a shorter overall duration of the mission (thus simplifying the logistics of the crew and time in space) and it has more frequent planetary alignments than Mars (every 19 months versus 26 months for Mars), “they explained.

A UA, or astronomical unit, is approximately 93 million miles, which is the distance between Earth and the sun.

COULD GO TO COME WITH TODAY’S TECHNOLOGY, SAY SCIENTISTS

A flyby mission of Venus could take less than a year – “shorter than some missions to the International Space Station,” wrote the experts, but would have exposed the astronauts to “higher levels of solar radiation comparable to those on a flight to Mars, although slightly reduced galactic cosmic radiation due to solar shading. “

The document was subject to peer review at Acta Astronautica.

Venus, which has been called “the evil twin of the Earth”, has an extremely harsh climate, with a surface temperature of 864 degrees Fahrenheit. It’s probably too hot to support life, but NASA recently said it plans to explore the planet.

In late 2019, NASA claimed it was working on a stingray-like spacecraft to explore the planet, which has more volcanoes than any other celestial body in the Solar System.

A study released in September 2019 suggested that Venus may have been habitable for a few billion years – until something mysterious happened.

NASA’S PERSERVERFANCE ROVER TRANSPORTING “SPECIAL” HIDDEN MESSAGE TO MARS

NASA’s next mission to Mars involves the recently renamed Perseverance rover, which is slated to launch “no earlier than July 30th”.

The Perseverance rover will attempt to detect if there is fossil evidence of extraterrestrial beings, in addition to other tasks.
