This week, Americans celebrated the successful delivery of NASA's Perseverance rover to its destination on the Martian surface, marking the dawn of a new era of interplanetary exploration. However, when it comes to searching the solar system around us, the US has not always led from the front. During the Reagan administration, for example, the agency saw its budget pared down in favor of building up arms ahead of an anticipated Cold War faceoff with the Soviet Union, as we see in this excerpt from David W Brown's latest work, The Mission. Excerpted from the book THE MISSION: or: How a Disciple of Carl Sagan, an Ex-Motocross Racer, a Texas Tea Party Congressman, the World's Worst Typewriter Saleswoman, California Mountain People, and an Anonymous NASA Functionary Went to War with Mars, Survived an Insurgency at Saturn, Traded Blows with Washington, and Stole a Ride on an Alabama Moon Rocket to Send a Space Robot to Jupiter in Search of the Second Garden of Eden at the Bottom of an Alien Ocean Inside of an Ice World Called Europa (A True Story) 2021 by David W. Brown. For planetary scientists, the Jimmy Carter–Ronald Reagan years were in retrospect like the Dark Ages, and they, the monks tending in enclaves to the embers of civilization.

Conclusion. In light of these priorities, it is critical that companies managing big data or developing and deploying artificial intelligence (AI) and machine …

NASA's Perseverance team has already begun its work from Mars' surface and released incredible images on Friday taken from the rover. In a news conference, experts said they could only hope the photographs from their mission might be able to contribute to already iconic images from years of space exploration. "And, I'm happy to say that I'm hopeful that we can contribute with this," NASA Jet Propulsion Laboratory (JPL) Mars 2020 Chief Engineer Adam Steltzner stated. In the first image revealed, Perseverance is shown approaching its landing site in Mars' Jezero Crater and hanging just 6.5 feet over the ground.

Generative adversarial neural networks (GANs) [1] [2] [3] [4] are deep learning (DL) models whereby a dataset is used by an agent, called the generator, to sample white noise from a latent space and simulate a data distribution to create new (fake) data that resemble the original data it has been trained on. Another agent, called the discriminator, has to correctly discern between the original data (provided by the external environment for training) and the fake data (produced by the generator). The generator prevails over the discriminator if the latter does not succeed in distinguishing anymore the original from the fake. The discriminator prevails over the generator if the fake data created by the generator is categorized as fake, and the original data is still categorized as original. An illustration that describes a GANs model is shown in Figure 1.

Elated NASA scientists Friday pored through the first landing scenes transmitted by the space agency's Perseverance rover on Mars. In the most dramatic image, a camera aboard the Perseverance landing system captured a close-up of the one-ton six-wheeled mobile robot suspended just a few yards above the surface of the red planet, where it successfully touched down Thursday, after a 292-million-mile journey from Earth. Hanging from the cables used to lower it from the lander to the ground, the rover resembled a high-tech marionette dangling on strings. "You can see the dust kicked up by the rovers' engines," said Adam Steltzner, Perseverance chief engineer at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "It was stunning and the team was awestruck. And, you know, there is just a feeling of victory that we were able to take these."

The image you see above was taken just moments before NASA's Perseverance rover successfully landed on the surface of Mars, and it's just the first of many high-resolution photos to come. NASA pulled the image from a video of the rover's descent that is in the process of being transmitted to Earth. "This shot from a camera on my'jetpack' captures me in midair, just before my wheels touched down," the rover's official Twitter account said. NASA's Curiosity rover and Mars Reconnaissance Orbiter caught Perseverance's trip to the surface as well. Every picture tells a story.

The concept of digital twin is not new. The technology has been around since the 1960s. NASA has been physically creating duplicate systems for its various space missions at ground level, to test its equipment in a virtual environment. An example of this is Apollo 13, for which a digital twin was developed by NASA to assess and simulate conditions on board. In the recent past, digital twin has become one of the most promising technological trends.

NASA says its Perseverance rover is in'great shape' after successfully landing on the surface of Mars last night after a 239 million-mile journey. The landmark landing shortly before 4pm ET (9pm GMT) was watched live by millions as NASA live streamed the process to millions of eager viewers. The $2.2billion car-sized rover guided itself to a patch of smooth terrain in Jezero, a 28-mile wide and 820ft-deep crater which was home to a Martian lake 3.5 billion years ago. Perseverance, nicknamed Percy, survived the dreaded'seven minutes of terror' which saw it endure temperatures in excess of 2,000 F as it entered the Martian atmosphere at more than 12,000mph. Perseverance beamed back its first image of the crater moments after NASA established radio contact with the rover, leading to raucous applause and joyous scenes at NASA's Californian mission control. Flight controller Swati Mohan announced to relieved colleagues: 'Touchdown confirmed! Perseverance safely on the surface of Mars, ready to begin seeking signs of past life.' 'The good news is the spacecraft, I think, is in great shape,' said Matt Wallace, Deputy Project Manager of Mars 2020. Perseverance will spend the next two Earth years scouring for signs of life in the crater and will perform a host of experiments.

Los Angeles – NASA's science rover Perseverance, the most advanced astrobiology laboratory ever sent to another planet, streaked through the Martian atmosphere on Thursday and landed safely on the floor of a vast crater, its first stop on a search for traces of ancient microbial life on the Red Planet. Mission managers at the U.S. space agency's Jet Propulsion Laboratory near Los Angeles burst into applause, cheers and fist-bumps as radio beacons signaled that the six-wheeled rover had survived its perilous descent and arrived within its target zone inside Jezero Crater, site of a long-vanished Martian lake bed. "Touchdown confirmed," Swati Mohan, the lead guidance and operations specialist announced from the control room. The robotic vehicle sailed through space for nearly seven months, covering 293 million miles (472 million km) before piercing the Martian atmosphere at 12,000 miles per hour (19,000 km per hour) to begin its descent to the planet's surface. Moments after touchdown, Perseverance beamed back its first black-and-white images from the Martian surface, one of them showing the rover's shadow cast on the desolate, rocky landing site.
