Ever since human beings first saw it as a star-like object in the night sky, Mars has intrigued humanity. Early on, the planet’s crimson tint was something that set it apart from its gleaming companions, all of which shine in their own bright ways.
Afterward, in the latter part of the 1800s, some pretty advanced telescopes were invented. These telescopes revealed a surface brimming with interesting features. Scientists got to see patterns and landforms that they initially mistook for signs of a busy Martian civilization. However, we now know that there are no man-made structures on Mars. But we have also gathered enough evidence that shows that the arid, hazardous planet we see now may have been as livable as Earth until 3.5 billion years ago.
Since the 1960s, hundreds of exploration missions of Mars have been launched to discover more about our neighboring celestial body. Some of them were successful, most were not. Apart from Earth, Mars now has more spacecraft at operation than any other planet.
Perseverance Rover / Ingenuity Helicopter (Mars 2020) #
Is there any evidence of evolution on Mars? NASA’s Mars Exploration Program has been diligently trying to discover for years. The agency’s Spirit and Opportunity rovers discovered evidence of liquid water on the surface. On the heels of that finding, NASA’s Curiosity rover discovered that circumstances on Mars 4 billion years ago may have supported life as we know it. Perseverance would then go straight for indications of a prior life.
The Perseverance Rover or I launched on July 30, 2020, against the backdrop of the worldwide COVID-19 epidemic. It landed at the Jezero crater on February 18, 2021, the place of an old lake and river delta. The rover will look for microbial remains in rocks generated during Mars’ warm and wet past. It will also look out for hydrocarbons, that is carbon-containing chemicals that are the building blocks of life on Earth. Since 1976, when the twin Viking wanders conducted long-shot chemical analyses that yielded unsatisfactory findings, NASA has not explicitly looked for life on Mars.
The Ingenuity Helicopter, on the other hand, is a tiny robotic helicopter that is part of NASA’s Mars 2020 mission, which landed on February 18, 2021, along with the Perseverance rover. On April 19, two months later, Ingenuity achieved the first motorized interplanetary voyage by an aircraft, lifting off vertically, hovering, and landing for a total flight time of 39.1 seconds. The helicopter has completed 18 effective flights as of December 15, 2021.
InSight - NASA’s Discovery Mission #
InSight, which stands for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport, was flown to Mars in May 2018 and arrived in November of the same year. Its goal is to understand more about the layers that make up Mars’ interior so that scientists may correlate it to what we understand about the other planetary systems and Earth.
Since the terrain at the landing location was different than expected, one of InSight’s key research equipment, a heat-flow probe known as the mole, failed to perform. InSight is now on a longer mission, listening for Marsquakes to learn more about what lies under the Martian surface.
Over the course of the project’s lifespan, NASA will spend $814 million on InSight.
Mars Atmospheric and Volatile Evolution (MAVEN) #
MAVEN (Mars Atmospheric and Volatile Evolution) is NASA’s second Mars Scout mission, which is a competition for smaller, more economical missions led by a principal scientist. MAVEN is acquiring key indicators of the Martian atmosphere to better comprehend tremendous climatic change on the red planet during its history, in response to high-priority research goals outlined in the National Academy of Science’s 2003 decanal study on space missions.
It arrived at Mars on September 22, 2014, and was placed in an elliptic orbit about 6,200 kilometers (3,900 miles) above the planet’s surface, with a radius of 150 kilometers (93 miles).
MAVEN presents insight on when and how rapidly atmospheric elements are lost to space presently, as well as drawing conclusions as to what actually occurred from those precise examinations. Examining how the Martian atmosphere ceased to exist can offer information on the influence that transition had on the Martian temperature, geology, and geochemical conditions over time.
In 2017, MAVEN detected a tangled magnetic tail behind the planet, which was disclosed at the time. The MAVEN mission of NASA has detected “layers” and “rifts” in Mars’ electrically charged upper atmosphere (ionosphere). The phenomenon is pretty prevalent on Earth and causes radio communications to be disrupted in unanticipated ways.
‘Curiosity’ Rover or the Mars Science Laboratory #
The Mars Science Laboratory, which includes the Curiosity rover, can be deemed as NASA’s most ambitious Mars mission to date. In 2012, the rover landed on Mars with the primary aim of determining if Mars is or was favorable for life. Another goal is to understand more about the environment on Mars.
Curiosity’s size is one of the things that makes it so unique: it’s approximately the size of a compact SUV. It’s roughly 7 feet high (2.1 m) and is 9 feet 10 inches long by 9 feet 1 inch broad (3 m by 2.8 m). It is 2,000 pounds in weight (900 kilograms). The wheels of Curiosity are 20 inches (50.8 cm) in diameter.
It traveled from Gale Crater to Aeolis Mons (commonly known as Mount Sharp) in March 2018 to commemorate 2,000 sols (Mars days) on the planet, looking at geological information hidden in the mountain’s strata. It has also discovered considerable traces of water and geological change along the way.
Mars Reconnaissance Orbiter (MRO) #
The most sophisticated camera ever flown on a planetary research mission, NASA’s Mars Reconnaissance Orbiter, was launched in August 2005. It is intended for focusing on certain aspects of the Martian landscape with unprecedented clarity. Older cameras on Mars orbiters could only detect items the size of a dining table, but this camera can detect anything as small as a dinner plate. This capacity not only gives an incredible level of data about Mars’ geology and configuration but also aids in identifying hazards that might compromise the stability of subsequent wanders and rovers.
During its EDL phase, the orbiter sailed over Gale crater, the landing site of the Mars Science Laboratory mission, on August 6, 2012 (sol 2483). It acquired a photograph of the Curiosity Rover falling with its backshell and supersonic parachute using the HiRISE camera.
Mars Odyssey #
Ever since 2001, NASA’s Odyssey spacecraft has been circling Mars, thus setting the record for the longest continuously operating spacecraft orbiting a planet other than Earth.
The mission’s initial objectives were to look for traces of water, create precise maps of the planet’s ground elements, and evaluate radiation levels for human researchers.
The Odyssey orbiter serves as a communications relay for the Mars Exploration Rovers “Spirit” and “Opportunity,” as well as the Mars Phoenix Lander and the Mars Science Laboratory’s Curiosity rover. Mars Odyssey’s images and other measures aid in the identification of prospective landing locations for space probes.
The Hubble Space Telescope #
All we know about our universe came from findings with the naked human eye from the start of humanity until around 400 years ago. Eventually, in 1610, Galileo pointed his telescope towards the stars. The world was about to be changed radically.
The Hubble Telescope is named after Edwin Hubble, who discovered galaxies beyond our own in the 1920s at the Mt. Wilson Observatory in Pasadena, California, using the greatest telescope of his day.
Hubble has been used by scientists to study the most distant stars and galaxies, as well as our solar system’s planets. In April 1990, Hubble was launched and deployed, marking the greatest important achievement in astronomy since Galileo’s telescope.
In today’s world, the Hubble Space Telescope (HST) is capable of taking very close-up images of Mars. In 2008, and again in 2016, a beautiful snapshot of Mars was published. HST can detect objects up to 8 km in size at its maximum resolution.
In April 1990, Hubble was launched and deployed, marking the greatest important advancement in astronomy since Galileo’s telescope. Our perspective of the cosmos and our existence within it has not been the same ever since all due to the five servicing missions and more than 30 years of its operation.
Future of Mars Exploration Missions #
NASA successfully managed to land the Perseverance rover on Mars in 2021. Its objective is to look for evidence of life and gather rocks and soil samples in preparation for a return to Earth mission in the future.
Following NASA missions, in collaboration with the European Space Agency, spacecraft would be sent to Mars to collect these sealed samples from the surface and return them to Earth for further research.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration strategy, which includes Artemis Moon missions that will aid in the preparation of the first manned exploration trip to Mars.
Humans are likely to inhabit Mars by the year 2050 if automatic mining methods prove commercially feasible rapidly. Professor Serkan Saddam of UNSW Sydney thinks so, following NASA’s Perseverance rover’s incredible landing on Mars. Perseverance is intended to reveal answers as to whether life ever existed on Mars, as well as address the obstacles that future human expeditions would face there.
