Politicians tried to express their views about such a que sera sera approach to rocket safety without causing a diplomatic incident. For instance, when Skylab, the first US space station, came down from orbit inNASA failed in its attempt to steer it into the ocean and ended up smearing it across Western Australia. Again, no one was hurt. This went unpaid untilwhen a Californian radio DJ raised the funds from listeners as a publicity stunt.
In a not-at-all tenuous link, another challenge of a similar difficulty to controlling de-orbiting rocketry is the question of how to curb numbers of feral pigeons in town centres. Now, councillors in Hungerford, a market town in the south of England, have had a different idea: humanely trapping the birds and releasing them more than kilometres away, at the seaside town of Whitby in North Yorkshire.
Therefore, many experts called the fossilized evidence pseudofossils. Still, the structures are very similar to microbial signatures on Earth, and an ancient biological origin on Mars cannot be written off. Life On Mars new research published in by Ildiko Gyollai et al.
Comparing recent results and interpretation with other meteorites, it Life On Mars be concluded, that on these similarities the microbially mediated biosignatures can be proposed microbial mediation by FeOB [iron oxidizing bacteria] on Mars.
Finding possible microscopic evidence is one thing, but for many years around the turn of the 20th century, people believed that a large civilization of beings lived on Mars. It all started when an Italian astronomer, Giovanni Schiaparelli, trained his 22cm telescope on Mars in He wanted to catalog and map the Red Planet, which until then, nobody else had done.
He noted that there were areas of the planet that were darker than others and assumed these were seas. As the regions were planet-wide, he postulated that they were somehow connected. The features appeared linear and likely reached distances of hundreds of kilometers in length. These features came to be known, wrongly, as canals. The media of the time went into overdrive, claiming that Schiaparelli had discovered alien-made canals on Mars.
One even postulated that the purpose of the canals was Life On Mars move water from the wetter Martian poles during a severe drought on the rest of the planet. Then in the early 20th century, bigger telescopes helped scientists understand that the channels were simply optical illusions, not alien-made structures.
As the s drew to a close, the days of merely observing space ended when the Soviet Union successfully launched an artificial satellite. The space race was born, and countries set their sights on the Moon and Mars. However, getting a probe to Mars proved elusive. A substantial number of early missions failed. The teething troubles were so pronounced that scientists joked about the Great Galactic Ghoul : the fictional entity that sabotaged as many missions as possible.
After almost two decades of trying, humankind finally got its first look at another world. Two Viking Landers not only reached the Life On Mars surface but also transmitted data back to Mission Control. Even before touching down, images taken of the region of Mars called Cydonia caused a considerable sensation. NASA tried to explain it away as our human tendency to find familiar images within inanimate objects, such as the clouds. Still, not everyone accepted that as an explanation.
Many people clung to the idea that a complex lifeform had created the face. Making matters worse, additional features dotted around the structure looked like eroding buildings. After another hiatus, Mars once again became the focus of attention during the s. Pathfinder was a revolutionary spacecraft that touched down on the surface of Mars in It possessed a parachute to slow down its descent and a cocoon of airbags to cushion its fall.
Sojourner, the robotic rover, was designed to investigate multiple areas. Opportunity E. Viking 2 G. InSight H. Curiosity I. Perseverance F. Jezero Crater rim. Target landing site for Perseverance.

Mars has long captured our imagination, from claims of canals to Martian attacks and now our latest NASA exploration to look inside the red planet.
But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?
