After 44 Years, China Becomes the Third Country To Return Moon Samples To Earth (scmp.com) 45

Long-time Slashdot reader cusco writes: In the first return of a lunar sample since the Soviets in 1976, the Chang'e 5 spacecraft landed Thursday in Inner Mongolia with 2 kilograms of material drilled from as much as two meters below the surface... On December 3, the ascent stage took off from the moon with the sample, docking with the orbiter three days later. After jettisoning the ascent stage the orbiter returned to Earth and was recovered December 17.

Here's a (fairly bad) video of the drilling and sample acquisition, and a video of the recovery, with an IR camera shot showing the hot lander and what appears to be a fox running past.

China's 23-day mission makes it only the third country to return samples from the moon, reports the South China Morning Post, while the drill sites are "believed to be much younger than that of the locations sampled by the Americans and the Russians..." Chinese President Xi Jinping on Thursday said space exploration knew no limits and called for new interplanetary exploration to turn China into a major power in space and realise national rejuvenation, as well as the peaceful use of space... The lander vehicle of the Chang'e 5 also for the first time unfolded a Chinese five-star national flag on the moon and will hold it there permanently, as it was abandoned after being used as a launch pad for the ascending vehicle...

With the successful completion of the mission, the Chang'e lunar programme aims to land Chinese astronauts on the nearest celestial body by 2030, and set up a permanent research space on the south pole of the moon in the future. China's space ambition goes beyond the moon. It sent a probe to Mars in July, and is preparing to launch a Chinese space station next year.

Scientists Say They Have Come Up With a Potential Way To Make Oxygen On Mars (cnn.com) 122

An anonymous reader quotes a report from CNN: In a high-stakes mission that could take five years to complete, NASA wants to land astronauts on Mars in the 2030s. Transporting enough oxygen and fuel on a spacecraft to sustain the mission for anywhere near that length of time, however, isn't currently viable. The way NASA plans to address this problem is by deploying MOXIE, or the Mars Oxygen in Situ Resource Utilization Experiment. This system is in the testing phase on the Mars Perseverance rover, which launched in July. The apparatus will convert the carbon dioxide that makes up 96% of the gas in the red planet's' atmosphere into oxygen.

On Mars, oxygen is only 0.13% of the atmosphere, compared to 21% of the Earth's atmosphere. The MOXIE system essentially produces oxygen like a tree -- pulling in the Martian air with a pump and using an electrochemical process to separate two oxygen atoms from each molecule of carbon dioxide, or CO2. The experimental technique proposed by Vijay Ramani and his colleagues uses a completely different resource -- salty water in lakes beneath the Martian surface. "The presence of the brine is fortuitous because it lowers freezing point of the water. You take the salty, brackish water and electrolyze that. Our process takes the water and splits it into hydrogen and oxygen," Ramani said. The method proposed in the new paper, however, assumes that these brines are readily available on Mars, said Michael Hecht, NASA's principal investigator for MOXIE and associate director for research management at the Massachusetts Institute of Technology's Haystack Observatory.
The study has been published in the journal PNAS.

Aliens In Hiding Until Mankind Is Ready, Says Ex-Israeli Space Head (nypost.com) 332

The former head of Israel's space program, Haim Eshed, says space aliens have reached an agreement with the U.S. government to stay mum on the experiments they conduct on Earth -- as well as their secret base on Mars -- until mankind is ready to accept them. The New York Post reports: "The aliens have asked not to announce that they are here [because] humanity is not ready yet," Eshed told Israeli paper Yedioth Aharonoth, according to the Jewish Press. The Jewish Press -- speculating that Eshed, 87, may have gone to insanity and beyond -- goes on to unspool his tangled web, which claims the involvement of President Trump and interplanetary diplomacy.

"Trump was on the verge of revealing [aliens existence], but the aliens in the Galactic Federation are saying, "Wait, let people calm down first,'" Eshed, who helmed Israel's space security program from 1981 to 2010, reportedly said. "They don't want to start mass hysteria. They want to first make us sane and understanding." Until that day, aliens have secured an agreement to keep their moves under wraps, said Eshed, noting that the extraterrestrials come in peace.

"There's an agreement between the U.S. government and the aliens. They signed a contract with us to do experiments here. They, too, are researching and trying to understand the whole fabric of the universe, and they want us as helpers." One of the hubs of the cooperation is a base on Mars -- where, by the way, Eshed claims American astronauts have already set foot. "There's an underground base in the depths of Mars, where their representatives are, and also our American astronauts," Eshed reportedly said.
Eshed added: "If I had come up with what I'm saying today five years ago, I would have been hospitalized. Wherever I've gone with this in academia, they've said, 'The man has lost his mind,'" he reportedly said. "Today they're already talking differently. I have nothing to lose. I've received my degrees and awards, I am respected in universities abroad, where the trend is also changing."

Elon Musk is Highly Confident SpaceX Will Land Humans on Mars by 2026 (cnbc.com) 229

SpaceX CEO Elon Musk remains highly confident that his company will land humans on Mars by 2026, saying on Tuesday that it's an achievable goal "about six years from now." From a report: "If we get lucky, maybe four years," Musk said, speaking on an award show webcast from Berlin, Germany. "We want to send an uncrewed vehicle there in two years." The ambitious 2026 goal matches with what Musk outlined at the International Astronautical Congress in September 2016, when he said that "if things go super well," landing people on Mars "might be kind of in the 10-year timeframe." "I don't want to say that's when it will occur -- there's a huge amount of risk," Musk said in 2016.

Are There Active Volcanoes on Mars? (yahoo.com) 29

Mars is a dead planet — "Or is it?" asks the New York Times: Previous research has hinted at volcanic eruptions on Mars 2.5 million years ago. But a new paper suggests an eruption occurred as recently as 53,000 years ago in a region called Cerberus Fossae, which would be the youngest known volcanic eruption on Mars. That drives home the prospect that beneath its rusty surface pocked with gigantic volcanoes that have gone silent, some volcanism still erupts to the surface at rare intervals. "If this deposit is of volcanic origin then the Cerberus Fossae region may not be extinct and Mars may still be volcanically active today," scientists at the University of Arizona and Smithsonian Institution, write in their paper — which was posted online ahead of peer review and has been submitted to the journal Icarus...

If it holds up to scrutiny, the discovery would have large implications for Mars. In geological terms, 53,000 years is the blink of an eye, suggesting Mars might well still be volcanically active now. It could also have big implications for the search for life on Mars. Such volcanic activity could melt subsurface ice, providing a potential habitable environment for living things.

"To have life, you need energy, carbon, water and nutrients," said Steven Anderson, an earth sciences professor at the University of Northern Colorado in Greeley, who was not involved in the paper. "And a volcanic system provides all of those."

Werner Herzog On Asteroids, Star Wars, and the 'Obscenity' of a City On Mars (inverse.com) 152

78-year-old filmmaker Werner Herzog shared some interesting thoughts before the release of his new documentary on asteroids, Fireball: Visitors From Darker Worlds now available on Apple TV+.

From Herzog's new interview with the science site inverse: Herzog tells Inverse he's less concerned than ever that a meteorite will destroy the Earth, but that doesn't mean we shouldn't still be worried about our own extinction. "It may be 100 million years to go until then," Herzog says, before adding, "within the next thousand years, we may have done such stupid things that we are not around anymore to contemplate it...."

There's a theory that all life on Earth came from a meteorite. Do you think that's possible...?

[I]f you expand the question, it wouldn't surprise me if we found life somewhere outside of our solar system, or even within our solar system, because we share the same chemistry with the universe. We share the same physics with the universe. And we share the same history with the universe. So with trillions and trillions and trillions of stars out there, it's highly likely that somewhere there are some forms of life. Probably not as good and interesting as in movies. We can be pretty certain there are no creatures out there like in Star Wars...

Have you heard the theory that we're living inside a simulation?

Yes, but I don't buy it. Because when I kick a soccer ball from the penalty spot, I know this is for real. If the goalie saves it, oh shit, this is for real.

He also discusses the 1998 asteroid disaster film Deep Impact and his own appearance on Rick and Morty, as well as part on The Mandalorian — and the experience of watching its premiere with 1,000 hardcore Star Wars fans. ("It was unbelievable. The first credit appears and there's a shout of joy that you cannot describe... It's evident Star Wars is a new mythology for our times, whether you like it or not.")

But though Herzog's films "often feature ambitious protagonists with impossible dreams, people with unique talents in obscure fields, or individuals who are in conflict with nature," according to Wikipedia, Herzog insists to Inverse that Elon Musk's plan to build a city on Mars is a "mistake."
In a blistering criticism, Herzog describes the idea as "an obscenity," and says humans should "not be like the locusts...."

Herzog is not opposed to going to Mars at all. In fact, the German filmmaker would "love to go [to Mars] with a camera with scientists." But the long-term vision of a Mars city is a "mistake." Herzog's main concern is that humanity should "rather look to keep our planet habitable," instead of trying to colonize another one.

In short, Mars is not a livable place. There is no liquid water at the surface, or air to breathe. Solar wind means inhabitants would be "fried like in a microwave," Herzog says.

Martian Dust Storms Parch the Planet By Driving Water Into Space (sciencemag.org) 15

sciencehabit writes: Two years ago, a global dust storm veiled Mars. But although the storm took a toll, killing off NASA's Opportunity rover, it also revealed that such storms play an important role in how the once-wet planet loses its water. In 2014, looking back at data from 2007, scientists noticed that the fluorescent fog of hydrogen in the martian upper atmosphere faded as the southern hemisphere's summer ended and a previous global dust storm subsided. The only plausible source for that hydrogen was water. Subsequent observations have indicated that water, buoyed by storms, can reach much higher in the atmosphere than previously thought -- all the way to the ionosphere, a new paper reports. This allows charged particles to directly break the water apart, and it is likely the primary method of water loss on the planet today.

SpaceX Will 'Make Its Own Laws On Mars' (independent.co.uk) 293

schwit1 writes: SpaceX will not recognize international law on Mars, according to the Terms of Service of its Starlink internet project. Elon Musk's space company will instead reportedly adhere to a set of "self-governing principles" that will be defined at the time of Martian settlement. Musk revealed plans to create a self-sustaining city on Mars last week, though no timeframe is yet to be put in place for its development. Any future colony created by SpaceX would likely use constellations of Starlink satellites orbiting the planet to provide internet connection to people and machines on the surface.

"For services provided on Mars, or in transit to Mars via Starship or other colonization spacecraft, the parties recognize Mars as a free planet and that no Earth-based government has authority or sovereignty over Martian activities," the governing law section states. "Accordingly, disputes will be settled through self-governing principles, established in good faith, at the time of Martian settlement." Space systems engineer Erwan Beauvois said SpaceX's position was reminiscent of a declaration put forward by the Earthlight Foundation, a non-profit organization committed to preparing for the expansion of humanity beyond Earth. The Declaration of the Rights and Responsibilities of Humanity in the Universe states that space should be "considered free, by all, for all and to all."

NASA Discovers a Rare Metal Asteroid That's Worth $10,000 Quadrillion (observer.com) 192

A reader shares a report from Observer: NASA's Hubble Space Telescope has discovered a rare, heavy and immensely valuable asteroid called "16 Psyche" in the Solar System's main asteroid belt between Mars and Jupiter. Asteroid Psyche is located at roughly 230 million miles (370 million kilometers) from Earth and measures 140 miles (226 kilometers) across, about the size of West Virginia. What makes it special is that, unlike most asteroids that are either rocky or icy, Psyche is made almost entirely of metals, just like the core of Earth, according to a study published in the Planetary Science Journal on Monday.

Given the asteroid's size, its metal content could be worth $10,000 quadrillion ($10,000,000,000,000,000,000), or about 10,000 times the global economy as of 2019. Using ultraviolet spectrum data collected by the Space Telescope Imaging Spectrograph on the Hubble Space Telescope during two observations in 2017, researchers deduced that Psyche's surface could be mostly pure iron. However, they recognized that the presence of an iron composition of as small as 10 percent could dominate ultraviolet observations. Psyche is the target of the NASA Discovery Mission Psyche, expected to launch in 2022 atop a SpaceX Falcon Heavy rocket. Further facts about the asteroid, including its exact metal content, will hopefully be uncovered when an orbiting probe arrives in early 2026. The asteroid is believed to be the dead core left by a planet that failed during its formation early in the Solar System's life or the result of many violent collisions in its distant past.

NASA's Perseverance Rover Is Midway To Mars (nasa.gov) 16

NASA's Mars 2020 Perseverance rover mission has logged a lot of flight miles since being lofted skyward on July 30 -- 146.3 million miles (235.4 million kilometers) to be exact. Turns out that is exactly the same distance it has to go before the spacecraft hits the Red Planet's atmosphere like a 11,900 mph (19,000 kph) freight train on Feb. 18, 2021. From a report: "At 1:40 p.m. Pacific Time today, our spacecraft will have just as many miles in its metaphorical rearview mirror as it will out its metaphorical windshield," said Julie Kangas, a navigator working on the Perseverance rover mission at NASA's Jet Propulsion Laboratory in Southern California. "While I don't think there will be cake, especially since most of us are working from home, it's still a pretty neat milestone. Next stop, Jezero Crater." The Sun's gravitational influence plays a significant role in shaping not just spacecraft trajectories to Mars (as well as to everywhere else in the solar system), but also the relative movement of the two planets. So Perseverance's route to the Red Planet follows a curved trajectory rather than an arrow-straight path.

"Although we're halfway into the distance we need to travel to Mars, the rover is not halfway between the two worlds," Kangas explained. "In straight-line distance, Earth is 26.6 million miles [42.7 million kilometers] behind Perseverance and Mars is 17.9 million miles [28.8 million kilometers] in front." At the current distance, it takes 2 minutes, 22 seconds for a transmission to travel from mission controllers at JPL via the Deep Space Network to the spacecraft. By time of landing, Perseverance will have covered 292.5 million miles (470.8 million kilometers), and Mars will be about 130 million miles (209 million kilometers) away from Earth; at that point, a transmission will take about 11.5 minutes to reach the spacecraft.

New Nuclear Engine Concept Could Help Realize 3-Month Trips To Mars (newatlas.com) 131

Seattle-based Ultra Safe Nuclear Technologies (USNC-Tech) has developed a concept for a new Nuclear Thermal Propulsion (NTP) engine that they claim is safer and more reliable than previous NTP designs and with far greater efficiency than a chemical rocket. The concept could reduce Earth-Mars travel time to just three months. New Atlas reports: According to Dr. Michael Eades, principal engineer at USNC-Tech, the new concept engine is more reliable than previous NTP designs and can produce twice the specific impulse of a chemical rocket. Specific impulse is a measure of a rocket's efficiency. To fuel the concept, UNSC-Tech uses a Fully Ceramic Micro-encapsulated (FCM) fuel to power the engine's reactor. This fuel is based on High-Assay Low Enriched Uranium (HALEU), which is derived from reprocessed civilian nuclear fuel and is enriched to between 5 and 20 percent -- greater than that of civilian reactors and less than that of naval reactors. The fuel is then encapsulated into particles coated with zirconium carbide (ZrC).

The company claims that this fuel is much more rugged than conventional nuclear fuels and can operate at high temperatures. This produces safer reactor designs and a high thrust and specific impulse that could previously only be obtained with highly-enriched uranium. In addition, such fuel can be produced with current supply chains and manufacturing plants. It is hoped the new concept could lead to nuclear engines that reduce deep space mission times drastically, with a crewed mission to Mars arriving in as little as three months. Beyond that, the concept is aimed at a commercial market as well as with NASA and the US Department of Defense, allowing for more ambitious private missions.

Vint Cerf Is Working on an Internet for Outer Space (quantamagazine.org) 86

"TCP/IP doesn't work at interplanetary distances," 77-year-old Vinton Cerf tells Quanta magazine. "So we designed a set of protocols that do." Specifically, bundle protocols: a disruption/delay-tolerant networking (DTN) protocol with nodes that can also store information: A data packet traveling from Earth to Jupiter might, for example, go through a relay on Mars, Cerf explained. However, when the packet arrives at the relay, some 40 million miles into the 400-million-mile journey, Mars may not be oriented properly to send the packet on to Jupiter. "Why throw the information away, instead of hanging on to it until Jupiter shows up?" Cerf said. This store-and-forward feature allows bundles to navigate toward their destinations one hop at a time, despite large disruptions and delays...

So, a couple decades after conceiving of bundle protocols, is the interplanetary internet up and running?

We don't have to build the whole thing and then hope somebody uses it. We sought to get standards in place, as we have for the internet; offer those standards freely; and then achieve interoperability so that the various spacefaring nations could help each other. We're taking the next obvious step for multi-mission infrastructure: designing the capability for an interplanetary backbone network. You build what's needed for the next mission. As spacecraft get built and deployed, they carry the standard protocols that become part of the interplanetary backbone. Then, when they finish their primary scientific mission, they get repurposed as nodes in the backbone network. We accrete an interplanetary backbone over time.

In 2004, the Mars rovers were supposed to transmit data back to Earth directly through the deep space network — three big 70-meter antennas in Australia, Spain and California. However, the channel's available data rate was 28 kilobits per second, which isn't much. When they turned the radios on, they overheated. They had to back off, which meant less data would come back. That made the scientists grumpy. One of the JPL engineers used prototype software — this is so cool! — to reprogram the rovers and orbiters from hundreds of millions of miles away. We built a small store-and-forward interplanetary internet with essentially three nodes: the rovers on the surface of Mars, the orbiters and the deep space network on Earth. That's been running ever since.

We've been refining the design of those protocols, implementing and testing them. The latest protocols are running back-and-forth relays between Earth and the International Space Station... We did another test at the ISS where the astronauts were controlling a little robot vehicle in Germany.

NASA To Announce New Science Results About Moon (nasa.gov) 59

NASA will announce an exciting new discovery about the Moon from the Stratospheric Observatory for Infrared Astronomy (SOFIA) at a media teleconference at 12 p.m. EDT Monday, Oct. 26. Audio of the teleconference will stream live on the agency's website. From a press release: This new discovery contributes to NASA's efforts to learn about the Moon in support of deep space exploration. Under NASA's Artemis program, the agency will send the first woman and next man to the lunar surface in 2024 to prepare for our next giant leap -- human exploration of Mars as early as the 2030s. Understanding the science of the Moon also helps piece together the broader history of the inner solar system.

NASA and Nokia To Install 4G on Lunar Surface (theguardian.com) 65

With competition among Earth's telecoms providers as fierce as ever, equipment maker Nokia has announced its expansion into a new market, winning a deal to install the first cellular network on the moon. From a report: The Finnish equipment manufacturer said it was selected by NASA to deploy an "ultra-compact, low-power, space-hardened" wireless 4G network on the lunar surface, as part of the US space agency's plan to establish a long-term human presence on the moon by 2030. The $14.1m contract, awarded to Nokia's US subsidiary, is part of Nasa's Artemis programme which aims to send the first woman, and next man, to the moon by 2024. The astronauts will begin carrying out detailed experiments and explorations which the agency hopes will help it develop its first human mission to Mars. Nokia's network equipment will be installed remotely on the moon's surface using a lunar hopper built by Intuitive Machines in late 2022, Nokia said. "The network will self-configure upon deployment," the firm said in a statement, adding that the wireless technology will allow for "vital command and control functions, remote control of lunar rovers, real-time navigation and streaming of high definition video."

Liquid Water on Mars? New Research Indicates Buried 'Lakes' (nbcnews.com) 42

The existence of liquid water on Mars -- one of the more hotly debated matters about our cold, red neighbor -- is looking increasingly likely. From a report: New research published Monday in the journal Nature Astronomy indicates there really is a buried reservoir of super-salty water near the south pole of the planet. Scientists say such a lake would significantly improve the likelihood that the red planet just might harbor microscopic life of its own. Some scientists remain unconvinced that what's been seen is liquid water, but the latest study adds weight to a tentative 2018 finding from radar maps of the planet's crust made by the Mars Express robot orbiter. That research suggested an underground "lake" of liquid water had pooled beneath frozen layers of sediment near the Martian south pole -- akin to the subglacial lakes detected beneath the Antarctic and the Greenland ice sheets on Earth.

Earth's subglacial lakes are teeming with bacterial life, and similar life might survive in liquid reservoirs on Mars, scientists have speculated. "We are much more confident now," said Elena Pettinelli, a professor of geophysics at Italy's Roma Tre University, who led the latest research and the earlier study. "We did many more observations, and we processed the data completely differently." The planetary scientist and her team processed 134 observations of the region near the south pole with ground-penetrating radar from the Mars Express Orbiter between 2012 until 2019 -- more than four times as many as before, and covering a period of time more than twice as long. They then applied a new technique to the observation data that has been used to find lakes beneath the Antarctic ice sheet, as well as an older technique used in the 2018 study. Both methods indicate there is a "patchwork" of buried reservoirs of liquid in the region, Pettinelli said -- a large reservoir about 15 miles across, surrounded by several smaller patches up to 6 miles across.

NASA Launches New $23 Million Toilet to International Space Station (space.com) 33

First, PetaPixel reminds us that Estee Lauder's products will be launching into space this week: The cosmetics giant Estee Lauder is paying NASA $128,000 for a product photography shoot onboard the International Space Station. Bloomberg reports that the company will be paying the space agency to fly 10 bottles of its Advanced Night Repair skin serum to the orbiting space station on a cargo run that will launch from Virginia on Tuesday and dock on Saturday. Once the product is on board, astronauts will be tasked with shooting product photos of the serum floating in the cupola module, which has sweeping panoramic views of Earth and space.

NASA charges a "professional fee" of $17,500 per hour for the astronauts' time.

In a possibly-related story, the same flight will also be carrying a new $23 million space toilet to the station as part of a routine resupply mission "to test it out before it's used on future missions to the moon or Mars."

Chitin Could Be Used To Build Tools and Habitats On Mars, Study Finds (arstechnica.com) 84

A team of scientists from the Singapore University of Technology and Design discovered that, using simple chemistry, the organic polymer chitin -- contained in the exoskeletons of insects and crustaceans -- can easily be transformed into a viable building material for basic tools and habitats. The findings have been published in the journal PLOS ONE. Ars Technica reports: "The technology was originally developed to create circular ecosystems in urban environments," said co-author Javier Fernandez. "But due to its efficiency, it is also the most efficient and scalable method to produce materials in a closed artificial ecosystem in the extremely scarce environment of a lifeless planet or satellite." [T]he authors of the current paper point out that most terrestrial manufacturing strategies that could fit the bill typically require specialized equipment and a hefty amount of energy. However, "Nature presents successful strategies of life adapting to harsh environments," the authors wrote. "In biological organisms, rigid structures are formed by integrating inorganic filler proceed from the environment at a low energy cost (e.g., calcium carbonate) and incorporated into an organic matrix (e.g., chitin) produced at a relatively high metabolic cost."

Fernandez and his colleagues maintain that chitin is likely to be part of any planned artificial ecosystem because it is so plentiful in nature. It's the primary component of fish scales and fungal cell walls, for example, as well as the exoskeletons of crustaceans and insects. In fact, insects have already been targeted as a key source of protein for a possible Martian base. And since the chitin component of insects has limited nutritional value for humans, extracting it to make building materials "does not hamper or compete with the food supply," the authors wrote. "Rather, it is a byproduct of it."

Elon Musk Says Settlers Will Likely Die on Mars (popularmechanics.com) 214

"But is that such a bad thing?" asks Popular Mechanics: Earlier this week, Elon Musk said there's a "good chance" settlers in the first Mars missions will die. And while that's easy to imagine, he and others are working hard to plan and minimize the risk of death by hardship or accident. In fact, the goal is to have people comfortably die on Mars after a long life of work and play that, we hope, looks at least a little like life on Earth...

[T]he trip itself will take a year based on current estimates, and applicants to settlement programs are told to expect this trip to be one way. It follows, statistically, that there's an almost certain "chance" these settlers will die on Mars, because their lives will continue there until they naturally end. Musk is referring to accidental death in tough conditions, but people are likely to stay on Mars for the duration either way.

When Mars One opened applications in 2013, people flocked to audition to die on Mars after a one-way trip and a lifetime of settlement. As chemist and applicant Taylor Rose Nations said in a 2014 podcast episode: "If I can go to Mars and be a human guinea pig, I'm willing to sort of donate my body to science...."

Musks exact words: "I want to emphasize that this is a very hard and dangerous, difficult thing, not for the faint of heart. Good chance you'll die, it's going to be tough going, but it will be pretty glorious if it works out."

SpaceX Launched and Landed Another Starship Prototype (cnbc.com) 81

"SpaceX took another step forward Thursday in developing its next-generation Starship rocket, conducting the second short flight test of a prototype in the past month," reports CNBC: Starship prototype Serial Number 6, or SN6, took off from the launchpad at SpaceX's facility in Boca Chica, Texas. It gradually rose to about 500 feet above the ground before it returned back to land, touching down on a concrete area near the launchpad. The flight test appeared to be identical to the test SpaceX conducted of prototype SN5 on Aug. 5...

The company is developing Starship with the goal of launching cargo and as many as a 100 people at a time on missions to the Moon and Mars.

SpaceX has been steadily building multiple prototypes at a time at the company's growing facility in Boca Chica. While SpaceX's fleet of Falcon 9 and Falcon Heavy rockets are partially reusable, Musk's goal is to make Starship fully reusable — envisioning a rocket that is more akin to a commercial airplane, with short turnaround times between flights where the only major cost is fuel. After SpaceX in May launched a pair of NASA astronauts in its first crewed mission, Musk pivoted the company's attention, declaring that the top SpaceX priority is now development of Starship. Musk said in an email obtained by CNBC that Starship's program must accelerate "dramatically and immediately..."

He expects Starship's first flight tests to orbit won't come until 2021, saying that SpaceX is in "uncharted territory."

Commenting on the test launch of the bulky spacecraft, Elon Musk tweeted "Turns out you can make anything fly haha."
