This week’s image comes from NASA’s Mars rover Perseverance as it explores the to Jezero Crater. The photo was posted last month. It has been a little while since we directly our attention at the Red Planet.

The image shows what may be the result of a fast-moving river some time in the past. In the NASA write-up accompanying the photo above, we read:

“Pinestand” is an isolated hill bearing sedimentary layers that curve skyward, some as high as 66 feet (20 meters). Scientists think these tall layers may also have been formed by a powerful river, although they’re exploring other explanations, as well.

“These layers are anomalously tall for rivers on Earth,” [postdoctoral researcher at NASA’s Jet Propulsion Laboratory in Southern California Libby] Ives said. “But at the same time, the most common way to create these kinds of landforms would be a river.”

This week’s image shows China’s launch of the Shenzhou 16 spacecraft earlier this week atop a Long March 2-F rocket. The launch included a three-man crew, one being the first civilian astronaut in the Chinese crew rotation, who will relieve the current crew on the Tiangong Space Station.

Second TROPICS Launch a Success

The second and final TROPICS satellites, also known as Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats, were launched late yesterday via a Rocket Lab rocket in New Zealand. The first pair were launched earlier this month.

Rocket Lab sent out this message:

Payload deployment confirmed! Congratulations to the launch team on our 37th Electron launch, and to our mission partners at @NASA @NASA_LSP @NASAAmes: the TROPICS constellation is officially on orbit!

NASA now has more eyes on the world’s weather patterns. The lead of NASA’s Earth Science Division, Karen St. Germain, stated:

As we move into hurricane season for 2023, TROPICS will be in position to provide unprecedented detail on these storms, helping us better understand how they form, intensify, and move across the ocean.

In Case You Missed It/Television: JWST on 60 Minutes

Last month 60 Minutes had a piece on the James Webb Space Telescope (JWST), titled The Origin of Everything, that provided viewers with more amazing images. I recommend the episode. I also plan to watch a few more times myself.

For a taste of the episode, here is Matt Mountain, who heads up JWST’s operations as president of the Association of Universities for Research in Astronomy, discussing the speckled images captured at the very start as engineers used a star to align the telescope’s 18 mirrors.

Matt Mountain: These were not artifacts from the detector. These were not strange stars. The whole of the sky was filled with galaxies. There was no empty sky. And that’s when I went, “This telescope’s going to be phenomenal.”

Scott Pelley: No empty sky? What do you mean by that?

Matt Mountain: On almost every image we’re taking now, we see galaxies everywhere. I mean, we took a simple picture of a planet in our own system, Neptune. You know, it was this beautiful orb just sitting there and we saw some rings. In the background are galaxies again. It tells us that our universe is filled with galaxies. We knew this theoretically but when you go out to the night sky, we’re used to saying, “Well, look up at the night sky, we see those stars.” We can no longer say that. We now have to say, “Look up at the night sky and there are galaxies everywhere.”

Scott Pelley: We call it space because we thought there was nothing out there.

Matt Mountain: There is no empty sky with James Webb. That is what we have discovered.

You can watch the episode here.

Space Stories: End of a Lunar Mission, Ancient Rivers on Mars, and the Second TROPICS Launch

Here are some recent stories of interest.

—Engadget: “NASA Ends its Lunar Flashlight Mission“

NASA has pulled the plug on its Lunar Flashlight project, which was designed to look for sources of ice on our nearest neighbor. The agency spent the last few months trying, and failing, to get the craft to generate the necessary amount of thrust to get the small satellite to its intended destination. Officials say that the issue was likely caused by debris buildup in the fuel lines, which prevented the CubeSat from working to its full potential. 

—Insider: “Photos from NASA’s Mars Rover Show the Red Planet’s Ancient Rivers were Much Wilder than Scientists First Thought“

NASA’s Mars Perseverance rover has taken new images that reveal that some of the red planet’s ancient rivers were much wilder than scientists previously thought. “It’s the first time we’re seeing environments like this on Mars,” Katie Stack Morgan, Perseverance’s deputy project scientist, said in a NASA release. Scientists studying rock formations, features, and valleys on Mars, so far, have found evidence to suggest Mars was once covered by water. 

—Businesswire: “Rocket Lab Sets Date for Second NASA TROPICS Launch to Deploy Storm Monitoring Constellation“

Rocket Lab USA, Inc., a leading launch and space systems company, is preparing for the second of two dedicated Electron launches to deploy a constellation of storm monitoring satellites for NASA. The launch, called ‘Coming To A Storm Near You,’ is scheduled for lift-off no earlier than 17:30 on May 22nd NZST from Rocket Lab Launch Complex 1 on New Zealand’s Mahia Peninsula. The launch follows on from the successful ‘Rocket Like a Hurricane’ Electron launch on May 8th 2023, which deployed the first two CubeSats of NASA’s TROPICS constellation. The ‘Coming To A Storm Near You’ launch will deploy the final two TROPICS CubeSats, completing the constellation.
