The Journey to Mars Begins in South Texas

Boca Chica’s residents have learned to live with a rocket company, or at least tolerate it, over more than five years. But SpaceX’s work is about to become even more disruptive. So the company has offered to buy their homes. Some have taken the offer. Others, such as McConnaughey, have rejected it, even as Musk prepares to launch a giant rocketship just a short hop from their houses. SpaceX is already hard at work on the next Starship prototype, and Musk says the company might launch it into orbit as soon as this year. “We love Texas,” James Gleeson, a SpaceX spokesperson, said in a statement, “and believe we are entering a new and exciting era in space exploration.”

Few people in this part of South Texas could have predicted the recent trajectory of their life when SpaceX moved in. They have become space fanatics and legal experts, Musk supporters and thorns in his side, trying to make sense of their place in a strange story that could someday end millions of miles away from Earth. All because they got new neighbors.

Tributes to Terrorism Victims are on Mars

In September 2001, Honeybee Robotics employees in lower Manhattan were building a pair of tools for grinding weathered rinds off rocks on Mars, so that scientific instruments on NASA’s Mars Exploration Rovers Spirit and Opportunity could inspect the rocks’ interiors.

That month’s attack on the twin towers of the World Trade Center, less than a mile away, shook the lives of the employees and millions of others.

Work on the rock abrasion tools needed to meet a tight schedule to allow thorough testing before launch dates governed by the motions of the planets. The people building the tools could not spend much time helping at shelters or in other ways to cope with the life-changing tragedy of Sept. 11. However, they did find a special way to pay tribute to the thousands of victims who perished in the attack.

An aluminum cuff serving as a cable shield on each of the rock abrasion tools on Mars was made from aluminum recovered from the destroyed World Trade Center towers. The metal bears the image of an American flag and fills a renewed purpose as part of solar system exploration.

Honeybee Robotics collaborated with the New York mayor’s office; a metal-working shop in Round Rock, Texas; NASA’s Jet Propulsion Laboratory in Pasadena, Calif.; and the rover missions’ science leader, Steve Squyres, at Cornell University, Ithaca, N.Y.

“It’s gratifying knowing that a piece of the World Trade Center is up there on Mars. That shield on Mars, to me, contrasts the destructive nature of the attackers with the ingenuity and hopeful attitude of Americans,” said Stephen Gorevan, Honeybee founder and chairman, and a member of the Mars rover science team.

Mars Missions Stop in Their Tracks as Red Planet Drifts to the Far Side of Sun

All of NASA’s spacecraft on Mars are about to find themselves on their own, running simplified routines and cut off from their masters on Earth. That’s because something big is about to come between the two planets — an electromagnetic energy source that’s too powerful to broadcast through or around: the sun.

During this period, known as the Mars solar conjunction, our home star and its corona pass between Earth and the Red Planet. Some radio signals might still get through, according to a statement from NASA’s Jet Propulsion Laboratory (JPL), but they aren’t reliable. Fortunately for all those distant robots, NASA knows this happens every couple years, and the machines are well prepared for the coming quiet period.

“Our engineers have been preparing our spacecraft for conjunction for months,” Roy Gladden, manager of the Mars Relay Network, said in the statement. “They’ll still be collecting science data at Mars, and some will attempt to send that data home. But we won’t be commanding the spacecraft out of concern that they could act on a corrupted command.”

Can We Prevent Phobos’ Inevitable Demise?

Mars has two natural satellites: Deimos and Phobos; the latter orbits Mars closer than any other moon orbiting the other planets in the solar system, and it’s currently undergoing a process known as orbital decay.

In short, this means that Phobos is slowly drifting closer to Mars over time. Perhaps unsurprisingly, this has an impact on the gravitational pull between Mars and Phobos. As this tug strengthens, the tidal forces exerted on Phobos are increased, and this quite literally tears the moon apart.

Phobos’ surface is covered in strange lines, and according to planetary scientists, these are ‘stretch marks’ that result from the tidal forces that are being exerted on the moon as it orbits Mars. If the moon’s orbital decay continues at its current rate, then the moon could be destroyed in the next several million years, resulting in a planetary ring around Mars.

This raises the question: could we save Phobos from a seemingly inevitable demise? Theoretically, we could, but it wouldn’t be easy or practical.

Archaeology On Mars – From The Fantastical To The Real

Rover and Pyramids on Mars GETTY

NASA’s Martian rover Opportunity breathed its last digital gasp this week. What was a busy scurrying robot picking over and investigating the Martian landscape is now a slowly decaying pile of metal and circuitry. That is to say, Opportunity has entered my world, the world of abandoned things that is archaeology.

Humans have been dreaming about Martian archaeology for well over a century now. When the Italian Astronomer Giovanni Schiaparelli described seeing canali on the surface of the red planet in 1877, many in the English-speaking world began to speculate that Schiaparelli was referring to artificially constructed canals. Percival Lowell became the largest champion of this interpretation. In his 1895 book “Mars,” Lowell claimed that the canals of Mars had been built by a desperate alien race seeking to salvage what water they could from the planet’s melting ice caps.

Yet all along this journey, the Martian landscape has become populated by actual human-made objects. Fourteen separate missions from four different space agencies have littered the surface of the Mars with not only landers and rovers, but heat shields, parachutes, and an untold number of broken bits. As an archaeologist, I love broken bits.

The things that people make and leave behind tell a different story then written history. A physical examination of landing sites on Mars would reveal critical details about why some landers arrived safely while others crashed to never be heard from again. Even the crashed landers tell a story of human triumph and ingenuity. One day, an astronaut will walk up to the original Viking 1 lander and marvel at the accomplishments of their ancestors. The material heritage we are currently scattering across the Martian surface will stand for centuries to come as a symbol of what we as human beings can do.

The new $1.37 billion border-security deal might save SpaceX’s launch site in Texas, where Elon Musk hopes to launch Mars rockets

Elon Musk’s aerospace company, SpaceX, is working around-the-clock to build a rocket-launch site at the southern tip of Texas.

Most immediately, SpaceX plans to fly a stainless-steel “test hopper” vehicle: a squat prototype for a much larger launch system that Musk calls Starship. When finished, that system — a Starship spaceship and Super Heavy rocket booster stacked together — may stand about 39 stories high.

SpaceX’s launch site is between one and three miles from the Mexican border. Firing off rockets to the moon or Mars from that site might be impossible, though, if a border wall cuts through the launch facility. Yet lawmakers said that is precisely what proposed maps from the US Department of Homeland Security showed, according to Bloomberg.

However, a $1.37 billion, 1,159-page border-security agreement drafted by a bipartisan group of lawmakers would spare SpaceX’s nascent launch site from DHS bulldozers.

“None of the funds made available by this Act or prior Acts are available for the construction of pedestrian fencing … within or east of the Vista del Mar Ranch tract of the Lower Rio Grande Valley National Wildlife Refuge,” the text states.

That wildlife refuge region encompasses SpaceX’s 50-acre site launch site.

Terra Mars – Artificial Neural Network’s (ANN) topography of Mars in the visual style of Earth

Rendering of the western hemisphere of Terra Mars generation 65
2019. Centered at the enormous canyon system Valles Marineris, also featuring some or Mars’ tallest mountains, including Olympus Mons—the tallest mountain in the solar system—on the west coast.

Created by SHI Weili, For this project, Terra Mars is a speculative visualisation by an ANN (artificial neural network) to generate images that resemble satellite imagery of Earth modelled on topographical data of Mars. Terra Mars suggests a new approach to creative applications of artificial intelligence—using its capability of remapping to broaden the domain of artistic imagination.

SHI welcomes different interpretations of Terra Mars. It can be enjoyed simply as a playful remix of the two planets, or one can relate this imaginary version to the astronomical facts. Maybe one can even consider this as a preview of a possible outcome of human’s terraforming efforts, or you just appreciate the sheer beauty of a planet that resembles our own.

The 2018 Mars Apparition

“Apparition” is the term astronomers use for the appearance of an object over some course of time. For Mars, it means when it first appears west of the Sun in the morning sky, after being lost in the glow. Earth moves faster in its orbit, so we catch up to Mars and pass it. When we’re closest to Mars and it’s opposite the Sun in the sky we say it’s at opposition. Mars rises at sunset and becomes an evening object. After that the Earth pulls ahead, Mars recedes, and some months later approaches the Sun from the east until it’s lost in the Sun’s glare once again, this time at dusk.

Opinion: Mars Beckons

Niv Bavarsky

The science and technology behind NASA’s latest space explorer to land on Mars are so awe-inducing that it’s hardly surprising when scientists commenting on the triumph drop their usual jargon to speak like excited schoolchildren.

“It’s nice and dirty; I like that,” was how Bruce Banerdt, the principal investigator behind the InSight mission, reacted when, shortly after setting down Monday on the flat and featureless Martian plain known as the Elysium Planitia, the lander beamed back an image speckled with red dust. “This image is actually a really good argument for why you put a dust cover on a camera. Good choice, right?”

Unlike the [rovers], InSight — Interior Exploration using Seismic Investigations, Geodesy and Heat Transport — is meant to stay in one spot and deploy instruments to measure marsquakes (yes, on Earth they’re “earthquakes”) in order to learn about what’s going on in the innards of the planet. One gizmo will take Mars’s temperature by hammering itself 16 feet below the surface. Deploying the instruments alone is expected to take two months, and the entire mission is meant to last a Martian year, roughly two Earth years.

What for? A random sampling of comments from the public suggests not everyone is convinced that digging on Mars is money well spent. But the basic answer is that whether it’s practical or not, humans will continue to explore the heavens so long as the moon, Mars and the myriad celestial bodies beyond fire our imagination and curiosity. What happened in the earliest days of the universe? How were Earth and its fellow planets formed? And the question of questions: Is there life out there?
