“It’s really hard to not look at the universe in a new light and not just have a moment that is deeply personal…It’s an emotional moment when you see nature suddenly releasing some of its secrets, and I would like you to imagine and look forward to that.”

NASA is looking for assistance to answer a few questions about Martian clouds:
What causes the atmosphere to get cold enough for carbon-dioxide to freeze out?
How do clouds change from day to night, or during different seasons, or in some years more than others?
What are the clouds made of?
You can help by searching through data acquired by the Mars Climate Sounder (MCS) on the Mars Reconnaissance Orbiter (MRO) collected during Mars Year 29, which was from December 2007 to October 2009. Using an entire Martian year of identified clouds will allow NASA to determine how mesospheric clouds change during different seasons on Mars, and assist with future machine-learning algorithms for other years’ worth of data.
Visit the Cloudspotting on Mars website to learn more about how you can help. It’s a fun way to be part of the scientific community as it gains a greater understanding of the one planet in the solar system we hope to visit in person in the near future.

Remember all of the chatter earlier this year about whether a SpaceX or Chinese rocket booster was about read to hit the Moon? Well, NASA’s Lunar Reconnaissance Orbiter recently located the crater created by this object – a strange double crater. NASA reported it found an eastern crater (18-meter diameter, about 19.5 yards) superimposed on a western crater (16-meter diameter, about 17.5 yards).
While NASA has not seen double craters when other booster rockets hit the Moon’s surface (yes, it does happen occasionally), it tried to explain this one:
The double crater was unexpected and may indicate that the rocket body had large masses at each end. Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank. Since the origin of the rocket body remains uncertain, the double nature of the crater may indicate its identity.
Now we just need to go back to Space X and the Chinese and ask a few more questions about the rocket booster in question. It is still doubtful we have an Elon Musk crater on the Moon. Time will tell.

NASA said it is ready for a real test of the Space Launch System (SLS) and Orion capsule after multiple dry-runs. Of course, the tests were not perfect, but NASA said it is ready for the next phase. The latest test was on June 20th. Following that, Tom Whitmeyer, deputy associate administrator for common exploration systems at NASA Headquarters, stated:
During the wet dress rehearsal activities, we have incrementally added to our knowledge about how the rocket and the ground systems work together, and our teams have become proficient in launch procedures across multiple sites. We have completed the rehearsal phase, and everything we’ve learned will help improve our ability to lift off during the target launch window…The team is now ready to take the next step and prepare for launch.
The uncrewed launch itself could be as early as late August. Under this phase of the project, called Artemis 1, the rocket, capsule, and ground control will get a rigorous test. As NASA explains:
During this flight, the spacecraft will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown. It will travel 280,000 miles from Earth, thousands of miles beyond the Moon over the course of about a four to six-week mission. Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before.
NASA has come a long way to get this this step. The various problems along the way is why you have such tests. And now the first phase is about ready. Fingers crossed…
This week’s photo is from the Hubble Space Telescope. It shows the Dwarf starburst galaxy Henize 2-10, which lies 34 million light years away. NASA notes that “The bright region at the center, surrounded by pink clouds and dark dust lanes, indicates the location of the galaxy’s massive black hole and active stellar nurseries.”
The image below better illustrates the link between the massive black hole and the related star formation. NASA explains:
A pullout of the central region of dwarf starburst galaxy Henize 2-10 traces an outflow, or bridge of hot gas 230 light-years long, connecting the galaxy’s massive black hole and a star-forming region. Hubble data on the velocity of the outflow from the black hole, as well as the age of the young stars, indicates a causal relationship between the two. A few million years ago, the outflow of hot gas slammed into the dense cloud of a stellar nursery and spread out, like water from a hose impacting a mound of dirt. Now clusters of young stars are aligned perpendicular to the outflow, revealing the path of its spread.
