  SpaceX Will Build Its Next-Gen Mars Rocket in Los Angeles

https://www.space.com/40332-spacex-will … geles.html

SpaceX will build its "BFR" spaceship at a new facility in the Port of Los Angeles, Mayor Eric Garcetti announced yesterday (April 16).

The company plans to use this ambitious new vessel — whose acronym name stands for "Big Falcon Rocket" (or a less-family-friendly version of that name) — to send people to Mars by 2024 and set up a colony on the Red Planet within the next 50 to 100 years. Elon Musk, SpaceX's founder and CEO, has said that the BFR could also send people to the moon, launch satellites to low Earth orbit, clean up orbital debris and transport passengers around Earth at record speeds.

Requiring additional space for this enormous new endeavor, SpaceX decided to open up a new facility in the Port of Los Angeles, located roughly 20 miles (32 kilometers) south of the company's headquarters in Hawthorne, California. [The BFR: SpaceX's Mars-Colonization Architecture in Images]

"Officially announcing that @SpaceX will start production development of the Big Falcon Rocket in the @PortofLA! This vehicle holds the promise of taking humanity deeper into the cosmos than ever before," Garcetti tweeted after his State of the City address.




Elon Musk has published a new study about his ambitious plans to colonize Mars with SpaceX 

http://www.businessinsider.com/elon-mus … udy-2018-3

SpaceX founder Elon Musk has spun his latest talk about Mars colonization into a second academic study.

Musk's full paper, titled "Making Life Multi-Planetary," was published online this month by the journal New Space. It's currently available to read for free.

"You want to wake up in the morning and think the future is going to be great — and that's what being a spacefaring civilization is all about," reads the beginning of the study. "It's about believing in the future and thinking that the future will be better than the past. And I can't think of anything more exciting than going out there and being among the stars."

If that line sounds familiar, that's because it comes from Musk's October 2017 presentation to the International Astronautical Congress.

As Musk explained in his new study and presentation, the spaceship can be refilled with fuel while in orbit, then fired off to the moon, Mars, or somewhere else in the solar system.

SpaceX's first missions to Mars would come in 2022 and 2024, according to Muks's plan — though he has emphasized that the timeline is "aspirational."

"People have told me that my timelines, historically, have been optimistic," Musk said at SXSW.

The first trip in 2022 would drop off equipment made to harvest water and carbon dioxide from the air and convert it into methane using solar energy. That fuel would be stored in depots to refill Earth-bound BFRs. The second trip in 2024 which would be crewed with astronauts.

NASA Finds Ancient Organic Material, Mysterious Methane on Mars 

https://www.nasa.gov/press-release/nasa … ne-on-mars

NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface.

The new findings – “tough” organic molecules in three-billion-year-old sedimentary rocks near the surface, as well as seasonal variations in the levels of methane in the atmosphere – appear in the June 8 edition of the journal Science.

Organic molecules contain carbon and hydrogen, and also may include oxygen, nitrogen and other elements. While commonly associated with life, organic molecules also can be created by non-biological processes and are not necessarily indicators of life.

“With these new findings, Mars is telling us to stay the course and keep searching for evidence of life,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters, in Washington. “I’m confident that our ongoing and planned missions will unlock even more breathtaking discoveries on the Red Planet.”

“Curiosity has not determined the source of the organic molecules,” said Jen Eigenbrode of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who is lead author of one of the two new Science papers. “Whether it holds a record of ancient life, was food for life, or has existed in the absence of life, organic matter in Martian materials holds chemical clues to planetary conditions and processes.”

Although the surface of Mars is inhospitable today, there is clear evidence that in the distant past, the Martian climate allowed liquid water – an essential ingredient for life as we know it – to pool at the surface. Data from Curiosity reveal that billions of years ago, a water lake inside Gale Crater held all the ingredients necessary for life, including chemical building blocks and energy sources.

“The Martian surface is exposed to radiation from space. Both radiation and harsh chemicals break down organic matter,” said Eigenbrode. “Finding ancient organic molecules in the top five centimeters of rock that was deposited when Mars may have been habitable, bodes well for us to learn the story of organic molecules on Mars with future missions that will drill deeper.”

Seasonal Methane Releases

In the second paper, scientists describe the discovery of seasonal variations in methane in the Martian atmosphere over the course of nearly three Mars years, which is almost six Earth years. This variation was detected by Curiosity’s Sample Analysis at Mars (SAM) instrument suite.

Water-rock chemistry might have generated the methane, but scientists cannot rule out the possibility of biological origins. Methane previously had been detected in Mars' atmosphere in large, unpredictable plumes. This new result shows that low levels of methane within Gale Crater repeatedly peak in warm, summer months and drop in the winter every year.

"This is the first time we've seen something repeatable in the methane story, so it offers us a handle in understanding it," said Chris Webster of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, lead author of the second paper. "This is all possible because of Curiosity's longevity. The long duration has allowed us to see the patterns in this seasonal 'breathing.'"

Finding Organic Molecules

To identify organic material in the Martian soil, Curiosity drilled into sedimentary rocks known as mudstone from four areas in Gale Crater. This mudstone gradually formed billions of years ago from silt that accumulated at the bottom of the ancient lake. The rock samples were analyzed by SAM, which uses an oven to heat the samples (in excess of 900 degrees Fahrenheit, or 500 degrees Celsius) to release organic molecules from the powdered rock.

SAM measured small organic molecules that came off the mudstone sample – fragments of larger organic molecules that don’t vaporize easily. Some of these fragments contain sulfur, which could have helped preserve them in the same way sulfur is used to make car tires more durable, according to Eigenbrode.

The results also indicate organic carbon concentrations on the order of 10 parts per million or more. This is close to the amount observed in Martian meteorites and about 100 times greater than prior detections of organic carbon on Mars’ surface. Some of the molecules identified include thiophenes, benzene, toluene, and small carbon chains, such as propane or butene.

In 2013, SAM detected some organic molecules containing chlorine in rocks at the deepest point in the crater. This new discovery builds on the inventory of molecules detected in the ancient lake sediments on Mars and helps explains why they were preserved.

Finding methane in the atmosphere and ancient carbon preserved on the surface gives scientists confidence that NASA's Mars 2020 rover and ESA’s (European Space Agency's) ExoMars rover will find even more organics, both on the surface and in the shallow subsurface.

These results also inform scientists’ decisions as they work to find answers to questions concerning the possibility of life on Mars.

“Are there signs of life on Mars?” said Michael Meyer, lead scientist for NASA's Mars Exploration Program, at NASA Headquarters. “We don’t know, but these results tell us we are on the right track.”

This work was funded by NASA's Mars Exploration Program for the agency’s Science Mission Directorate (SMD) in Washington. Goddard provided the SAM instrument. JPL built the rover and manages the project for SMD.

LIVE: Webcast of the UNISPACE+50 High-level Segment


In June 2018 the international community will gather in Vienna for UNISPACE+50. UNISPACE+50 will celebrate the fiftieth anniversary of the first United Nations Conference on the Exploration and Peaceful Uses of Outer Space. It will also be an opportunity for the international community to gather and consider the future course of global space cooperation for the benefit of humankind.

UNISPACE+50 will consist of two main parts:

A UNISPACE+50 Symposium, aimed at the broader space community, on 18 and 19 June; and
A special UNISPACE+50 High-level Segment of the 61 st session of the Committee on the Peaceful Uses of Outer Space (COPUOS) on 20 and 21 June.
From 22 to 29 June, COPUOS will revert to its regular session.

In addition, a UNISPACE+50 exhibition consisting of around 40 exhibitors will be held in the Rotunda of the VIC from 18 to 23 June. The exhibition will be open to the public on Saturday 23 June from 9.00am to 12.30pm.

Re: Mars or Bust

Asgardia...I have heard about this. Well, there are times when kingdoms are formed. Is there not a royal family? Who are they?
Aren't Asgardians a little late to the party? When do they meet up with other pioneers?

Does a new calendar, and time keeping method begin? (i.e. stardates)? I thought the "Universal Time" idea was groovy, but doesn't time flow differently in high altitude planes, let alone various proposed "space arks"?
