Top NASA tech that solved Mars myths and mysteries like never before
Asteroid
1/10 Humans have been studying Mars for hundred of years. In 1609, Galileo was the first person to peer through a telescope and get a more intimate image of what many could only have dreamed of. (Pixabay)

2/10 An up close and personal view of the red planet emerged as time progressed and so did the capabilities of telescopes. In fact, from the late 1800s to the mid 1900s, many astronomers believed that Mars was home to majestic seas and lush areas of vegetation. The Dark markings on Mars surface were once believed to be caused by vegetation growing and dying. (Pixabay)

3/10 Some even believed that intelligent life existed on Mars just because of what they saw through their simple telescopes. But that is exactly was science is about-you make educated guesses based on what you know, then change your ideas based on what you learn. (NASA)

4/10 Now, thanks to new sophisticated equipment and robotic visits to Mars, it turns out they were caused by Martian wind. It was not until the 1960s, when NASA's Mariner missions flew by and snapped pictures of Mars that many of the myths about the red planet were dispelled. (NASA)

5/10 That does not make Mars any less interesting. The possibility that life actually existed once on Mars is still a distinct possibility. Or it may even be existing on Mars today! No, not in the form of little green men, but on a microbial level. (NASA)

6/10 Now, taking pictures is great and all. But nothing is better than getting to know the real thing. So, to get a better feel of Mars, Scientists and engineers built some nifty technologies, from spacecrafts to reach Mars and rovers (vehicles) to actually trundle and explore the planet. (NASA/JPL)

7/10 Among the earliest tech deployed for Mars was Phoenix. It was launched on August 4, 2007 and so began its 9-month long, 681 Million km journey to the legendary red planet. Now, landing on a planet is not as easy as simply dropping a spacecraft onto it. There is actually a lot of steps to the process. (NASA)

8/10 On May 25, 2008, Phoenix entered Mars atmosphere. It used its heat shield to slow down the high speed entry of 5600 meters per second or around 12500 miles per hour. It released a supersonic PARACHUTE, then detached from its parachute and used its rocket engines to land safely on the planet's surface. Phoenix' landing spot was further north and closer to the ice covered poles than any spacecraft has ever been before. (NASA)

9/10 Phoenix had two primary goals: One was to study the history of water in the Martian arctic and the other was to search for evidence of a habitual zone and assess the biological potential of the ice soil boundary. And to do that the spacecraft was packed full of gizmos and gadgets to perform all sets of experiments and tests. One of these gizmos was a robotic arm with a shovel attached. It was used to dig up samples of the martian soil for experiments! (NASA)

10/10 Another top tech on the Mars surface was the Surface Stereo Imager, which is really just a fancy name for the camera. Three surface stereo imagers were Phoenix' eye. Engineers built the device with two optical lenses that would allow for a three dimensional view, just like our eyes. And the SSI sent back some amazing images of the martian landscape.

All you need to know about the 98 foot asteroid 2022 WU11. (Pixabay)

Potentially, a giant asteroid collision with Earth can have a disastrous consequences, so much so, that it can even end life on the planet. Notably, the era of dinosaurs ended because of a massive asteroid collision with the planet. Space is full of asteroids. Most of the asteroids are found orbiting the Sun between Mars and Jupiter within the main asteroid belt. However, some of the asteroids do make an occasional trip to planet Earth too. To make sure that these asteroids nearing Earth do not pose any threat, NASA keeps an eye on them by tracking them constantly.

A giant 98-foot asteroid named 2022 WU11 is zooming towards Earth at a fiery speed today, December 17, according to NASA's Jet Propulsion Laboratory (JPL). As per the information, this airplane sized asteroid will make its closest approach to the planet at a distance of 4.4 million kilometers. Also, it is nearing Earth at a speed of 38026 kilometers per hour.

According to sky.org, the asteroid2022 WU11 belongs to the Apollo group of asteroids and was recently discovered on November 27. The asteroid takes 1176 days to complete a trip around the Sun during which its maximum distance from the Sun is 513 million kilometers. While the nearest distance is 139 million kilometers.

In order to monitor these asteroids, there are several Earth and Sky-based technologies like telescopes, satellites, and more deployed by NASA in space. NASA keeps a constant eye on the movements of the asteroids to ensure any kind of threat is quickly found and they can take quick action against it.
