This NASA-ISRO Mission Set to Crunch Key Space Data in Cloud

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)

SpaceX Plans To Send NASA Astronauts To Space in Q2 This Year

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff

After NASA and SpaceX successfully completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket, Elon Musk said that his aerospace company aims to send NASA astronauts to space between April and June this year.

This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station (ISS) under NASA’s Commercial Crew Programme, the US space agency said in a statement on Sunday.

With this test now complete, the next big flight of the Crew Dragon will have people on board: NASA astronauts Bob Behnken and Doug Hurley.

“We’re highly confident that the hardware will be ready in Q1, most likely at the end of February but no later than March. And we think it appears probable that the first crewed launch would occur in the second quarter,” said Musk after the successful uncrewed test of its Crew Dragon capsule’s in-flight launch escape capabilities.

Musk said that if all goes well, the first crewed flight on the Crew Dragon could take place in the second quarter of this year.

“This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil,” said NASA Administrator Jim Bridenstine. “We are thrilled with the progress NASA’s Commercial Crew Programme is making and look forward to the next milestone for Crew Dragon.”

As part of the test on Sunday, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 am just off the Florida coast in the Atlantic Ocean.

“As far as we can tell thus far, it’s a picture perfect mission. It went as well as one can possibly expect,” said Musk. “This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I’m super fired up. This is great.”

Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX’s Demo-2 mission. “The past few days have been an incredible experience for us,” said astronaut Doug Hurley.

“Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can’t wait to take a ride to the space station soon,” he said in the NASA statement. (IANS)
