Here are some recent stories of interest.

—America Space: “Falcon Heavy Launches, GOES-U Heads for Geostationary Orbit“

SpaceX successfully launched its first Falcon Heavy of the year on Wednesday evening, the triple-barreled booster lifting the 11,000-pound (5,000-kilogram) Geostationary Operational Environmental Satellite (GOES-U) almost to Geostationary Earth Orbit (GEO) on behalf of the National Oceanic and Atmospheric Administration (NOAA). The Heavy—flying for the first time since November 2022 with a brand-new center core and pair of side-mounted strap-on boosters—went airborne from historic Pad 39A at Florida’s Kennedy Space Center (KSC) at 5:26 p.m. EDT, ten minutes after the opening of a two-hour “launch window”.

—European Space Agency: “Jupiter’s Upper Atmosphere Surprises Astronomers“

The Great Red Spot of Jupiter was observed by Webb’s Near-InfraRed Spectrograph (NIRSpec) in July 2022, using the instrument’s Integral Field Unit capabilities. The team’s Early Release Science observations sought to investigate if this region was in fact dull, and the region above the iconic Great Red Spot was targeted for Webb’s observations. The team was surprised to discover that the upper atmosphere hosts a variety of intricate structures, including dark arcs and bright spots, across the entire field of view. “We thought this region, perhaps naively, would be really boring,” shared team leader Henrik Melin of the University of Leicester in the United Kingdom. “It is in fact just as interesting as the northern lights, if not more so. Jupiter never ceases to surprise.”

—University of Warsaw: “Is Dark Matter Made of Black Holes?“

Gravitational wave detectors, LIGO and Virgo, have detected a population of massive black holes whose origin is one of the biggest mysteries in modern astronomy. According to one hypothesis, these objects may have formed in the very early Universe and may compose dark matter, a mysterious substance filling the Universe. A team of scientists from the OGLE (Optical Gravitational Lensing Experiment) survey from the Astronomical Observatory of the University of Warsaw have announced the results of nearly 20-year-long observations indicating that such massive black holes may comprise at most a few percent of dark matter. Another explanation, therefore, is needed for gravitational wave sources. The results of the study were published in two articles, in Nature and the Astrophysical Journal Supplement Series.

Podcast: A Mixed Week for Musk

While things appear to be going Elon Musk’s way with his ridiculous Tesla pay package, The Wall Street Journal had another story this week that discussed his self-serving management style that should not merit reward. The article, “Elon Musk’s Boundary-Blurring Relationships With Women at SpaceX,” highlights some pretty horrible behavior for a man that then and now believes he is above the law (and all codes of decency).

If you cannot read the Journal article, you can find summaries of the story elsewhere or listen to the Wall Street Journal podcast called The Journal. The podcast is titled “Elon Musk’s Unusual Relationships With Women at SpaceX.”

It is scary that the US space program is so dependent on the behavior of this man, who has already been part of prior Wall Street Journal articles about his drug use.

We need to build greater depth in our space program, be it Blue Origin, Boeing, Northrop Grumman, Rocket Lab, or others. The dream of a stronger space program could die if we tie too much to one man.

Space Stories: Truncated Artemis III Mission, Origins of a Local Galaxy, and Chandra X-ray Observatory Exoplanet Efforts

Here are some recent stories of interest.

—Ars Technica: “As NASA Watches Starship Closely, Here’s What the Agency Wants to See Next“

NASA and SpaceX are planning for the possibility of modifying the Artemis III mission. Instead of landing on the Moon, a crew would launch in the Orion spacecraft and rendezvous with Starship in low-Earth orbit. This would essentially be a repeat of the Apollo 9 mission, buying down risk and providing a meaningful stepping stone between Artemis missions. Officially, NASA maintains that the agency will fly a crewed lunar landing, the Artemis III mission, in September 2026. But almost no one in the space community regards that launch date as more than aspirational. Some of my best sources have put the most likely range of dates for such a mission from 2028 to 2032. A modified Artemis III mission, in low-Earth orbit, would therefore bridge a gap between Artemis II and an eventual landing.

—Sci.News: “Astrophysicists Offer Explanation for Origin of One of Milky Way’s Largest Satellites“

The satellite galaxy Crater II (or Crater 2) of the Milky Way is located approximately 380,000 light-years away from Earth in the constellation of Crater. This galaxy is extremely cold and exceptionally diffuse, and has low surface brightness. According to new research, Crater II exists thanks to a self-interacting dark matter.

—Harvard-Smithsonian Center for Astrophysics: “Coming in Hot: NASA’s Chandra Checks Habitability of Exoplanets“

Using NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy potential conditions for life as we know it. This type of research will help guide observations with the next generation of telescopes aiming to make the first images of planets like Earth. A team of researchers examined stars that are close enough to Earth that future telescopes could take images of planets in their so-called habitable zones, defined as orbits where the planets could have liquid water on their surfaces. Any images of planets will be single points of light and will not directly show surface features like clouds, continents, and oceans. However, their spectra — the amount of light at different wavelengths — will reveal information about the planet’s surface composition and atmosphere.

Pic of the Week: Forth Starship Test is a Success

This week’s image shows the launch of the forth test of SpaceX’s Starship, which went further than any of the tests to date. In it’s summary of the flight, SpaceX noted:

Flight 4 ended with Starship igniting its three center Raptor engines and executing the first flip maneuver and landing burn since our suborbital campaign, followed by a soft splashdown of the ship in the Indian Ocean one hour and six minutes after launch.

You can see the full flight in this video.

As with yesterday’s successful launch of Boeing’s Starliner, today’s successful flight gave NASA greater assurance that the commercial sector is picking up the pace to assist the U.S. with both the International Space Station and Artemis program to the Moon (and eventually Mars).

Note: I like The Economist’s headline on the mission: “Elon Musk’s Starship Makes a Test Flight Without Exploding.”

Space Quote: More Musk Mayhem on the Ukrainian Front

Posted on by onespaceman2000

“Musk has taken on the role of apologist for indicted war criminal Vladimir Putin. “There is no way in hell that Putin is going to lose,” Musk said during an audio event on X. Musk called on social media followers to lobby the Senate not to pass an aid package for Ukraine. Further, Musk is actively working to thwart US foreign policy. Musk is certainly entitled to voice his opinions. However, he is not authorized to conduct foreign policy with FCC issued licenses. This is especially true when his use of those licenses supports the military of a foreign power that is actively engaged in an illegal war and has engaged in countless war crimes including routinely targeting hospitals, schools, and apartment buildings. Musk’s company is licensed to serve the public interest, convenience, and necessity. Musk cannot use FCC licenses to militarily aid Russia, a state that is subject to U.S. sanctions. Musk’s repeated abuse of the Starlink system has placed these licenses in jeopardy.”
