Here are some recent space-related stories.

—European Space Agency: “Smile Lifts Off on Quest to Reveal Earth’s Invisible Shield Against the Solar Wind“

The Smile spacecraft lifted off on a Vega-C rocket from Europe’s Spaceport in French Guiana at 04:52 BST / 05:52 CEST (00:52 local time) on 19 May 2026. The launch marks the beginning of an ambitious mission to better understand solar storms, geomagnetic storms, and the science of space weather…Smile is a collaboration between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS). It will reveal how Earth responds to the streams of particles and bursts of radiation from the Sun, using an X-ray camera to make the world’s first X-ray observations of Earth’s magnetic shield, and an ultraviolet camera to watch the resulting northern lights non-stop for 45 hours at a time.

—The Guardian: “Nasa Selects Jeff Bezos’s Blue Origin for First of Three Uncrewed Lunar Missions“

Nasa announced on Tuesday ambitious plans for three uncrewed lunar missions this year to kickstart construction of a $20bn moon base, and said it had chosen the Amazon founder Jeff Bezos’s Blue Origin, ahead of Elon Musk’s SpaceX, to conduct the first...[NASA’s Administrator] said the three missions planned for 2026 would be followed by “more than a dozen” more in the coming years to test systems and equipment. He said the highly successful Artemis II mission last month that sent four astronauts around the moon for the first time since 1972 had been both a catalyst and incentive to advance the moon base plan.

—Astrobiology: “Astronomers Observe Exoplanet Atmospheres With New Cloud-detecting Method“

Every morning, clouds roll in, and by evening, they have cleared off. This sounds like a weather forecast for a coastal city here on Earth — but it’s for WASP-94A b, a well-studied gas giant orbiting a star located nearly 700 light-years away. A new study published in the journal Science documents the first detection of repeating cloud cycles on a hot Jupiter exoplanet. The first author of the study is Sagnick Mukherjee, a 51 Pegasi b postdoctoral fellow at Arizona State University’s School of Earth and Space Exploration. Mukherjee is part of a research team that analyzed data from the James Webb Space Telescope targeting WASP-94 A b, a gas giant in the constellation Microscopium. The team discovered that the planet’s morning side is blanketed in clouds of magnesium silicate, the same mineral found in common rocks, while its evening side is under clear skies.

Twelfth Starship Launch Successful

Fortunately, the first SpaceX Starship launch of the year (and the twelfth for the rocket) went well yesterday with only a few bumps along the way. While it was not perfect, given that it was the first test of a new version of the rocket, it was a good night for the rocket-maker and NASA.

Here is SpaceX’s description of some of the bumps last night:

Following stage separation, the Super Heavy booster performed a directional flip maneuver and attempted its boostback burn. It was unable to light all planned engines and performed a partial boostback burn that ended early. Super Heavy attempted to reignite its engines for the landing burn before experiencing a hard splashdown in the Gulf of America. During its ascent burn to space, Starship lost one of the Raptor 3 vacuum engines but demonstrated its engine-out capability and achieved its planned trajectory.

This latest test is encouraging, but would be more encouraging is a solid schedule of more tests this year to ensure the Starship will be ready for the Artemis III low Earth orbit tests next year. SpaceX is still significantly behind schedule on it launches. For instance, this twelfth launch was delayed many times.

Both SpaceX and Blue Origin are racing to be part of the Artemis III test in late 2027 to see if NASA is really ready for a crewed landing on the Moon in 2028. This latest launch brings SpaceX that much closer.

ISS Mission Launched, Starship Launch Delayed

Delays abound, but at least one space mission successfully launched this week. After delays earlier this week, today the CRS-34 mission successfully launched towards the International Space Station (ISS). The Dragon capsule, carrying supplies for the Expedition 74 Crew on the station, is expected to dock with the ISS Sunday morning.

The first launch this year of the SpaceX Starship was not so lucky. While is was scheduled to launch today as well, it was delayed until Tuesday, May 19th. This will be the 12th test of the new rocket.

SpaceX has planned a long list of objectives related to the booster and rocket on this flight:

The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch.

The Starship upper stage will target multiple in-space and reentry objectives, including a payload deployment of 20 Starlink simulators, similar in size to next-generation Starlink V3 satellites, and two specially modified Starlink satellites. The two modified satellites will test hardware planned for Starlink V3 and will attempt to scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test. All of the deployed payloads will be on the same suborbital trajectory as Starship. A relight of a single Raptor engine while in space is also planned.

For Starship entry, a single heat shield tile has been intentionally removed to measure the aerodynamic load differences on adjacent tiles when there is a tile missing. Finally, the ship will perform experimental actions tested on previous flight tests, including a maneuver to intentionally stress the structural limits of the vehicle’s rear flaps and a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly.

It appears SpaceX is trying to make up for numerous delays with a single mission – a mission that is critical to the success of NASA’s Artemis program as well as SpaceX’s upcoming IPO.

Space Stories: Meteor Shakes Ohio, Executive Order Could Impact Pluto, and Musk May Muck Up Space Again

Here are some recent space-related stories of interest.

—Fox 8 News: “NASA Confirms Boom was 17,000-pound Meteor“

A loud “boom” was reported across Northeast Ohio just before 9 a.m. on Tuesday. People around Northeast Ohio flooded the FOX 8 newsroom with reports of what heard like a “large explosion” lasting several seconds and causing homes and businesses to “shake.” NASA has confirmed a 6-foot, 17,000-pound meteor traveled 44,000 miles per hour over northeast Ohio. It was 50 miles above Lake Erie when the first flash was detected.

—USA Today: “NASA’s Isaacman Latest to Endorse Trump Reclassifying Pluto as a Planet“

President Donald Trump campaigned on “America first,” but some of his supporters and appointees apparently want Pluto to once again be … ninth. The ninth planet in our solar system, that is. Ever since Pluto was infamously stripped of its planetary status two decades ago, debate has raged for years over the distant icy world – half the size of the United States – and just what sort of cosmic body it should be classified as. Now, Jared Isaacman, NASA’s new chief, has appeared to signal his support for Trump to designate Pluto as a planet once again through executive order.

—Newsweek: “New 1M‑Satellite Plans Could ‘Permanently Scar’ Night Sky, Astronomers Warn“

The Royal Astronomical Society (RAS) has issued a stark warning over proposals by Elon Musk’s SpaceX and the California-based startup Reflect Orbital, saying the plans could cause lasting damage to ground‑based astronomy and dramatically alter the night sky for skywatchers. In comments submitted to U.S. regulators, the RAS said the scale and brightness of the proposed satellite constellations risk overwhelming astronomical observations from Earth. The society, alongside the European Southern Observatory (ESO), has formally opposed both projects in filings to the Federal Communications Commission (FCC), where the companies have sought approval.

Audit Report: Questions about the Human Landing System

Posted on by onespaceman2000

Auditors with NASA’s Office of the Inspector General (OIG) evaluated three aspects of the Human Landing System (HLS) to be used with the Artemis Moon landing: (1) the extent to which the HLS providers are meeting cost, schedule, and performance goals; (2) the HLS Program’s implementation of the insight/oversight model; and (3) the Program’s identification and mitigation of risks to astronaut safety.

In its report, NASA’s Management of the Human Landing System Contracts, the auditors found issues in all three areas. In particular, the report stated:

…both SpaceX and Blue Origin have experienced schedule delays and face technical and integration challenges that have the potential to further impact lander costs and delivery schedules. In particular, SpaceX’s lander will not be ready for a June 2027 lunar landing.

It is possible that the draft version of this audit report was already the desk of NASA Administrator Isaacman right before he decided to move the Moon landing date again. Pending audit reports have a tendency to stir action.

Yet, even once we get to the moon, the auditors identified some safety issues. Specifically, the auditors stated:

We also observed limitations in the Agency’s approach to crew survival analyses—the evaluation of available crew survival capabilities to counter a catastrophic event—due to functional constraints and the availability of resources…While NASA is taking steps to prevent catastrophic events from occurring, ultimately, should the astronauts encounter a life-threatening emergency in space or on the lunar surface, NASA does not have the capability to rescue the stranded crew.

None of this is too surprising with a new approach like this one. Delays are inevitable, and even the best of plans cannot account for everything, as Apollo 13 demonstrated. It also shows that NASA has a tough balancing act, with the need for speed weighed against the mechanisms to ensure the safety of the astronauts.

One of the safety concerns stated later in the report really should have been its own report. It discussed the height of the HLS. As shown in the image above, the Starship Lander is huge compared to the Apollo lander and even Blue Origin’s Blue Moon Lander. Here are the dimensions per the report:

Landers may also encounter hazards such as boulders or mounds that are too large or depressions that are too deep for the landing legs and stability design. For example, steep slopes of up to 20 degrees on the lunar South Pole present navigation and landing challenges. Given Starship’s height of 171 feet— about the equivalent of a 14-story tall commercial building—there is a risk that its momentum will continue after landing causing it to tip over. Blue Moon—standing at 53 feet tall—also faces landing risks, including exceeding the lander’s tilt tolerance for safe and effective execution of critical crew functions. Surpassing the tilt tolerance for either lander, which NASA established as not to exceed 8 degrees to support all post-landing crew activities, could impact the operation of equipment such as the hatch used by the crew to exit and enter the vehicle. By comparison, the Apollo Lunar Module stood 23 feet tall.

This is scary given the multiple spacecraft we have already witness toppling over onto the lunar surface just last year. Why would we ever want to land a 14-story tall rocket with an elevator on the Moon as our first attempt after 50 years? I can understand Elon Musk proposing this ridiculous idea, but it is not clear how the original planners could have gone along with it. This is a “catastrophic event” waiting to happen.

The auditors also added a Apollo 15 Lunar Module story (shown below) to the report. After reading this report and the Apollo 15 clip, I think I will also have trouble sleeping tonight due to an uncomfortable feeling that the current Artemis approach was a mess (if not doomed) from the start.
