SpaceX CEO Elon Musk Scouting for Potential Mars Landing Sites

Musk has already estimated the cost of having a self-sustaining civilization on the Red Planet which is “between $100 billion and $10 trillion”

Elon Musk is serious about colonizing Mars and his aerospace company SpaceX has requested NASA to provide it with potential landing sites on the Red Planet.

SpaceX’s HiRise images indicate it is interested in the Arcadia region of Mars, which has both volcanoes and large open plains.

SpaceX is currently building two orbital prototypes and just completed a successful short jump of its Starhopper prototype as a test of its Raptor engine, reports CNET.

SpaceX is building the “Starship” (formerly known as the BFR), a fully reusable vehicle designed to take humans and supplies to Mars.

In an interview with Axios, Musk said that that there is “70 per cent chance that he will go to Mars”, despite a “good chance” of him not surviving either on the way or after landing.

Musk earlier floated the idea that making Mars warmer would be crucial for making it habitable for humans and one way of doing it would be launching thermonuclear weapons in order to create tiny “suns” over the regions.

The idea is to convert any frozen carbon dioxide into gas, thereby engineering a greenhouse gas.

Musk then floated a new theory, without abandoning the nuking Mars idea.

“Might make sense to have thousands of solar reflector satellites to warm Mars vs artificial suns (tbd),” he tweeted.

“Nuke Mars refers to a continuous stream of very low fallout nuclear fusion explosions above the atmosphere to create artificial suns. Much like our sun, this would not cause Mars to become radioactive,” he added.

Musk has already estimated the cost of having a self-sustaining civilization on the Red Planet which is “between $100 billion and $10 trillion”.

He arrived at the figure after estimating the approximate future cost of sending a minimum payload to Mars “to nearest order of magnitude”, at $100,000 per tonne. So if building a self-sustaining city on Mars requires a million tonnes of cargo, the cost would be around $100 billion, Musk calculated.

Companies such as SpaceX and scientific bodies around the world have been working towards inventing technologies to allow humans to venture beyond Earth’s moon but it could still take a decade or more before that is attempted. (IANS)

As the humankind aims for deeper space missions like Mars in couple of years from now, the time is to democratize humongous data available via NASA and space agencies like the Indian Space Research organization (ISRO) that can boost space research via next-gen Cloud computing, a top NASA-JPL official has stressed.

Scheduled for launch from Sriharikota launch facility in Andhra Pradesh in 2022, the NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between the US and Indian space agencies to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite. The satellite will be the first radar imaging one to use dual frequencies (L and S Band).

ISRO is likely to spend Rs 788 crore while JPL’s work share is expected to be over $800 million on this key project.

Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, NISAR satellite is designed to observe and take measurements of some of the planet’s most complex processes — ecosystem disturbances, ice-sheet collapse and natural hazards such as earthquakes, tsunamis, volcanoes and landslides.

Artificial Intelligence and Machine Learning-driven Cloud computing is certainly going to make the key difference once the satellite is up and running.

“NISAR is going to generate 100 terabytes per day. That’s a lot of data. It’s about a hundred times more than anything we’ve ever done together. It doesn’t fit in our data centres. So we have to put it in the Cloud,” Tom Soderstrom, Chief Innovation and Technology Officer, NASA JPL (Jet Propulsion Laboratory), told IANS during an interaction here.

“The data needs to be worked on for the Indian space agency with several others including NASA. Having it in the Cloud gives us a good place to store, analyse and parse it right for the benefit of humankind,” Soderstrom added.

The Jet Propulsion Laboratory is a federally-funded research and development center in Pasadena, California.

“For our science data processing part, we discovered that we could use GPUs (graphic processing units) which were never done before. So, for NISAR, we tried GPUs and realized that it’s better, sometimes 100 times better, based on what you’re doing and overall four times faster,” Soderstrom explained.

The data collected from NISAR mission will reveal information about the evolution and state of Earth’s crust, help scientists better understand our planet’s processes and changing climate, and aid future resource and hazard management.

According to Soderstrom, now they can not only process data much faster but also switch between CPUs and GPUs, whichever is the cheapest.

“Cloud will help us process the data differently. Now, you have lots of interesting data for different spacecrafts. We can now apply machine learning to see trends — both in the science and telemetry data,” said the NASA-JPL executive.

At JPL, everyone has intelligent digital assistant Alexa at his or her desk, helping the staffers organise daily tasks while making sense of intrinsic data-sets.

“An intelligent digital assistant has two pieces to it. It knows who I am and also knows how long I’ve been there, meaning it knows my role. So it can tell me things that I need to know before I even know I need them. You can ask Alexa simple things like when is NISAR launching or how much data it is producing on a daily basis, or where my source data is coming from,” Soderstrom explained.

Alexa can tell you about the mission’s budget. It can tell you about the compute environment and “we can speak to it, type to it or text to it. We apply machine learning to make Alexa smarter and smarter over time”.

Soderstrom is also bullish on space collaborations between countries to create a better world.

“Interest in space helps everybody. And there’s a lot of commercial interest now. I think if there is a business to be made, commercial space will do that. When there is no business to be made that no one can make money, then the government should do that.

“If space becomes the business, then let the business people do it like Elon Musk began by transporting things to the International Space Station (ISS). JPL, on the other hand, wants to go and do things that have never been done before. So if people can go to the moon and mine it, so be it. Once Mars becomes commonplace, we’re going to Jupiter’s moon Europa in search of life,” elaborated Soderstrom. (IANS)
