To the news.

SpaceX’s technical director of engines has resigned. Now he wants to fly to Mars.

You may not have heard the name Tom Muller, but if you’re a space fan, you’re probably familiar with the technology he helped create: the Merlin rocket engine that powers the SpaceX Falcon 9 rocket, and the Draco thrusters that power the rocket. SpaceX Falcon 9. SpaceX Dragon spacecraft.

Mueller worked for 18 years at SpaceX before retiring. But, as he told me, “When I stopped creating, I found that I didn’t feel that way.”

Considered by many to be one of today’s leading engine specialists, Müller began sketching out a small engine. This engine is now named “Rigel” after the blue supergiant in the constellation of Orion. This became the cornerstone of Mueller’s new startup. momentum spacewhich he founded in September 2021. With the new venture, Müller wants Impulse to be the best option for economical and efficient transportation in space.

“It was supposed to be just for fun and not too serious, but then some ex-SpaceX employees started talking [to me] and wanted to help, and suddenly it became real,” he said. “Now it’s full.”

After 50 years of groundbreaking Landsat satellite imagery, NASA is ready for another 50

NASA’s Landsat satellite constellation has made history in Earth observation since the project was launched back in 1972, providing vast amounts of earth data for government, scientists and industry. Devin Koldevi of TechCrunch spoke to Jim Irons, who retired earlier this year as director of NASA’s Earth Sciences Division, about the history of the project and why it’s still relevant today.

Now myriads of constellations, like the constellation of Planet Labs, map the entire globe on a daily basis. This begs the question: why Landsat at all?

“Those of us who work with Landsat are very impressed with what commercial providers have achieved,” said Irons. “The message we want to convey is that Landsat complements this data, not replaces Landsat data. First, this open and transparent access is the key, and this is true of all data collected by NASA satellites.

“Secondly, the USGS maintains this 50-year archive of data. Is there a business case for companies to archive their data for decades so that we can observe the effects of climate change over the long term rather than just getting short bursts of data? I don’t know if there is a business case.”
