Elon Musk drops details for SpaceX Mars mega-colony

This futuristic render shows a collection of Starships hanging out on the surface of Mars. Elon Musk and SpaceX envision astronauts initially living out of the spaceships while constructing a more permanent human settlement on the Red Planet.

The first SpaceX Starship orbital prototypes aren’t even built yet, but Elon Musk already has big plans for his company’s spacecraft, which includes turning humans into an interplanetary species with a presence on Mars. He crunched some of the numbers he has in mind on Twitter on Thursday.

Musk doesn’t just want to launch a few intrepid souls to Mars, he wants to send a whole new nation. He tossed out a goal of building 100 Starships per year to send about 100,000 people from Earth to Mars every time the planets’ orbits line up favorably.

A Twitter user ran the figures and checked if Musk planned to land a million humans on Mars by 2050. “Yes,” Musk replied. The SpaceX CEO has suggested this sort of Mars population number before. This new round of tweets give us some more insight into how it could be done, though “ambitious” doesn’t do that timeline justice. Miraculous might be a more fitting description.

The distance between Earth and Mars gets reasonably close roughly every 26 months. Musk’s vision involves loading 1,000 Starships into orbit and then sending them off over the course of a month around prime time for a minimal commute. Travelers would still be looking at spending months on board before reaching the Red Planet.

NASA has big plans for returning astronauts to the Moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land?

A new paper published in Geophysical Research Letters will help by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface.

Water ice will be a key consideration for any potential landing site. With little room to spare aboard a spacecraft, any human missions to Mars will have to harvest what’s already available for drinking water and making rocket fuel.

NASA calls this concept “in situ resource utilization,” and it’s an important factor in selecting human landing sites on Mars. Satellites orbiting Mars are essential in helping scientists determine the best places for building the first Martian research station. The authors of the new paper make use of data from two of those spacecraft, NASA’s Mars Reconnaissance Orbiter (MRO) and Mars Odyssey orbiter, to locate water ice that could potentially be within reach of astronauts on the Red Planet.

“You wouldn’t need a backhoe to dig up this ice. You could use a shovel,” said the paper’s lead author, Sylvain Piqueux of NASA’s Jet Propulsion Laboratory in Pasadena, California. “We’re continuing to collect data on buried ice on Mars, zeroing in on the best places for astronauts to land.”

IKEA prioritises space for overhaul of living pod in Mars Desert Research Station

IKEA has redesigned the tiny living pod on the Mars Desert Research Station in Utah, filling its interior with space-saving furnishings.

The Mars Desert Research Station (MDRS) is a simulation site that’s designed to emulate the physical and psychological conditions of Mars, where groups of up to six scientists can visit to carry out investigations into the red planet.

Situated in southern Utah, the station comprises seven elements: a greenhouse, solar observatory, engineering pod, science building, robotics observatory, and a domed, two-floor living habitat nicknamed The Hab.

It measures just eight metres in diameter and is where scientists stay during their periods of research, which can last anything from one week to three months.

China Unveils Plan To Send Astronauts To Mars

Chinese first woman astronaut Liu Yang (L) together with her two male colleagues, Jing Haipeng (C) and Liu Wang (R) wave as they areintroduced during a press conference at the Jiuquan space base, north China’s Gansu province on June 15, 2012.

In a story published by state news network China Daily, the China Aerospace Science and Technology Corporation announced plans to send astronauts to the surface of Mars.

“Sending astronauts there will give man better opportunities to look for traces of life on Mars,” Pang Zhihao, a space technology researcher in Beijing told China Daily. “There are theories that Mars was very similar to Earth in terms of environment billions of years ago.”

According to the statement, it marks “the first time that China’s space industry has publicly unveiled a plan for manned missions to the red planet.”

SpaceX ‘excited’ about building moon bases and Mars cities at the same time

SpaceX has big dreams to build cities on Mars and bases on the moon at the same time, one of the plan’s key architects revealed over the weekend.

Paul Wooster, SpaceX’s principal Mars development engineer, explained that the Starship vessel under development is designed for versatility. That means, as the company aims to complete its first city on Mars by 2050, there’s no need to switch development priorities or move the focus to complete one or the other.

“The [Starship] system also opens up capabilities, for example, to deliver very large payloads to the moon, set up and operate lunar bases,” Wooster explained on Saturday at the 22nd annual Mars Society Convention at the University of Southern California. “Because it’s the same system that’s being used for going to the moon and going to Mars, it’s not something where you have to stop going to the moon in order to go to Mars…we’re really excited about the possibilities of doing both, having bases on the moon while we’re also setting up these cities on Mars.”

The xEMU suit improves on the suits previous worn on the Moon during the Apollo era and those currently in use for spacewalks outside the International Space Station and will be worn by first woman and next man as they explore the Moon as part of the agency’s Artemis program. The Orion suit is designed for a custom fit and incorporates safety technology and mobility features that will help protect astronauts on launch day, in emergency situations, high-risk parts of missions near the Moon, and during the high-speed return to Earth.

Today, NASA revealed the two spacesuits that it will use for its Project Artemis. It shared a video of a spacesuit engineer wearing a bulky, red-white-and-blue suit that will be used for work on the Moon and another spacesuit engineer rocking a thinner, orange suit. The latter is what the crew will wear on their way to and from the Moon, and in the event that there’s a sudden depressurization of their spacecraft, they’ll be able to live inside the suit for days.

People settling on Mars will to some degree have to live off the land. At its closest, our neighboring planet lies 35 million miles away. Transporting supplies there will cost roughly $5,000 per pound and take at least six months using current technology. Better to enlist the natural resources of their new home when possible, an approach called in situ resource utilization. “It totally changes the logistics of a mission,” says Advenit Makaya, a materials engineer who develops processes like 3D printing at the European Space Agency. “You don’t have to bring everything with you.”

Humans on the Red Planet might draw power from the sun, mine water from buried ice, and harvest oxygen from the atmosphere. With NASA’s encouragement, architects, engineers, and scientists are exploring how early residents might use recycled waste and the planet’s loose rock and dust, called regolith, to craft tools, erect homes, pave launchpads and roads, and more.

Rovers and probes have revealed enough about Martian geology for us to start figuring out how that might work. The surface contains an abundance of iron, magnesium, aluminum, and other useful metals found here at home. Scientists also believe the crust consists largely of volcanic basalt much like the dried lava fields of Hawaii.

NASA’s New Spacesuit: The xEMU

Exploration Extravehicular Mobility Unit (xEMU): EVA Spacesuit Technology and Design #SuitUp

NASA has announced the details of the first new spacesuit since the Space Shuttle, which will allow humans to return to the lunar surface and maybe even travel further beyond. But why does NASA need new spacesuits when they already have some in use?

When the Space Shuttle entered service, it came with a new spacesuit: the Extravehicular Mobility Unit (hence EMU). It remains the main operational spacesuit for NASA, despite its 30-year-old parts and even older design, and has allowed for many feats of human engineering. However, with this storied history has come deterioration: out of the original fleet of 14 flight-ready suits, only 8 remain thanks to a variety of accidents.

This inability to use current hardware has made the development of a new suit a major problem for the Artemis Program’s ambitions. As such, NASA has focused its resources on one suit design, as opposed to the many it was designing and studying previously: the xEMU, or Exploration Extravehicular Mobility Unit.

Building on the EMU’s basic design, the new xEMU will incorporate many design features of the 21st century. Compared to the old A7L suits from Apollo, the new suits will be more flexible, adaptable and much easier to put on, with multiple new features. These include a back entry port (similar to the port on Russia’s Orlan suit), modular design, high-speed data transceiver, sacrificial helmet shield (to protect from lunar dust), and HD video system, among many others.

Elon Musk has said that his Starship spacecraft – which is designed to carry people to the moon and Mars – will begin orbital test flights in less than two months. The SpaceX CEO made the comments during an evening presentation at Space X’s facility in Boca Chica, Texas, with the gigantic shiny spacecraft lit up in the background.

Musk first revealed plans for the rocket in 2016, updating them and calling the craft the Big Falcon Rocket (BFR) in 2017. Last year, he revised the design again and changed the rocket’s name to Starship. It is 118 metres tall and apparently capable of carrying about 100 people to the moon or Mars.

Getting mac and cheese to Mars

WSU graduate student Juhi Patel, an author on the mac and cheese paper, puts packages of purple potatoes into an incubator, which speeds up the food quality changes at a consistent rate.

Washington State University scientists have developed a way to triple the shelf life of ready-to-eat macaroni and cheese, a development that could have benefits for everything from space travel to military use.

If human beings go to Mars, they need food. Food that won’t spoil during the long travel between planets, and while they’re on the surface.

Currently, plastic packaging can keep food safe at room temperature for up to twelve months. The WSU researchers demonstrated in a recent paper in the journal Food and Bioprocess Technology they could keep ready-to-eat macaroni and cheese safe and edible with selected nutrients for up to three years.

“We need a better barrier to keep oxygen away from the food and provide longer shelf-life similar to aluminum foil and plastic laminate pouches,” said Shyam Sablani, who is leading the team working to create a better protective film. “We’ve always been thinking of developing a product that can go to Mars, but with technology that can also benefit consumers here on Earth.”

In addition to having space travel in mind, the researchers are working closely with the U.S. Army, who want to improve their “Meals Ready to Eat” (MREs) to stay tasty and healthy for three years.

In taste panels conducted by the Army, the mac and cheese, recently tested after three years of storage, was deemed just as good as the previous version that was stored for nine months.
