Washington, April 19, 2017: NASA’s Mars Reconnaissance Orbiter (MRO) has captured a region of Mars sprayed with mysterious secondary craters.

“Secondary craters form from rocks ejected at high speed from the primary crater, which then impacts the ground at sufficiently high speed to make huge numbers of much smaller craters over a large region,” NASA said in a statement on Tuesday.

“In this scene, however, the secondary crater ejecta has an unusual raised-relief appearance like bas-relief sculpture,” NASA added.

So how did that happen?

One idea is that the region was covered with a layer of fine-grained materials like dust or pyroclastics about one to two metres thick when the Zunil impact occurred (about a million years ago), and the ejecta served to harden or otherwise protect the fine-grained layer from later erosion by the wind, NASA scientists said.

NASA is inviting applications from start-ups to take part in a three-month pilot programme to develop new technologies for space.

Applications will be accepted till April 7 and a total of 10 companies will be selected for the programme, the US space agency said.

The accelerator programme will focus on technologies that can be applied to space — including geospatial analytics, digital design coupled to advanced manufacturing, autonomous systems, applied Artificial Intelligence (AI) and Machine Learning (ML).

“We want to assist these companies in developing their own technologies and becoming commercial successes. NASA will also benefit by collaborating with these companies,” said Tom Cwik, Manager of the Space Technology Office at Jet Propulsion Laboratory (JPL) in Pasadena, California.

Based in Los Angeles, the accelerator programme begins on July 15. After developing their concepts and business plans over a three-month period, the teams will then pitch their results to the NASA community, co-sponsors and private investors at a demo day in October, NASA said.

“Industry is developing new technologies rapidly, using new tools and methods in software development and other areas,” said Cwik.

“It’s incumbent upon us to learn from developments in industry and contribute our vast expertise in technology as we prepare to use them in our future missions,” Cwik added. (IANS)
