- The flight path taken by Hakuto-R1 as it entered Atlas Crater to attempt its lunar landing
According to the investigation, the software problem occurred as it flew over the north rim of the crater, causing later altitude data to be measured inaccurately.
- Ispace says Hakuto-R1 mission was insured
The link refers to “liability insurance”, which usually covers injury to yourself and others. It is unclear if Ispace’s insurance covered property loss.
- Blue Origin expanding its Alabama rocket facility for the third time
The local city council approved the sale of almost fifteen acres to the company. No word however if this means rockets and engines will actually finally appear from the factory.
- China touts the upgrades on its next six manned Shenzhou capsules
The upgrades apparently include more parts made domestically plus an upgraded control panel.
- Juice team completes full deployment of spacecraft, declaring it in “full flight configuration”
This last deployment involved the opening and positioning of several sensors on the spacecraft’s boom
A fractured spot in Mars’ northern lowland plains

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 16, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a pockmarked flat plain with a scattering of meandering hollows, each filled with ripple sand dunes that make these depressions resemble at first glance the tracks of tires.
Obviously, we are not looking at evidence of a past giant vehicle moving across the ground on Mars. The MRO science team labels these “fractures,” suggesting some past geological process caused the surface to crack in this manner, with those cracks widening with time due to erosion or sublimation.
The location of course tells us something about that process.

NASA inspector general finds more cost overruns in the agency’s SLS rocket program
Surprise! Surprise! A new NASA inspector general report [pdf] has found that the agency’s SLS rocket program is continuing to experience cost overruns and mismanagement that are “obscene”, as noted in this news report.
An independent report published Thursday contained troubling findings about the money spent by the agency on propulsion for the Space Launch System rocket. Moreover, the report by NASA Inspector General Paul Martin warns that if these costs are not controlled, it could jeopardize plans to return to the Moon.
Bluntly, Martin wrote that if the agency does not rein in spending, “NASA and its contracts will continue to exceed planned cost and schedule, resulting in a reduced availability of funds, delayed launches, and the erosion of the public’s trust in the agency’s ability to responsibly spend taxpayer money and meet mission goals and objectives—including returning humans safely to the Moon.”
Things are really much worse than this, mostly because it appears the Marshall Space Flight Center that runs the SLS program for NASA uses cost-plus contracts, which are essentially a blank check for contractors to run up costs endlessly, all of which the government must cover, and allows the process to go over-schedule against its own regulations. Furthermore, the cost overruns are for rockets and engines that are not newly developed, but in use for decades by Northrop Grumman and Aerojet Rocketdyne.
Note that this really isn’t news. Anyone with any intellectual honesty at all will know that every aspect of SLS and Orion is mismanaged and will go over budget and behind schedule endlessly. These problems are not a bug, however, but a feature of the system. The goals of SLS and Orion are not really to build a rocket to explore the solar system but to create an endless jobs program in congressional districts here on Earth. This misguided approach meanwhile robs America of a viable space effort because the money wasted could have actually been used to jumpstart a viable and competitive space-faring economy that actually achieves something.
Northrop Grumman wins $45.6 million contract to launch Space Force weather smallsat
Northrop Grumman has won $45.6 million contract from the Space Force to launch a weather smallsat, using its Minotaur-4 rocket that was formerly a military ICBM.
The weather satellite, built by General Atomics, is part of an effort by the military to stop building its big expensive and continuously delayed weather satellites and instead buy the services from the private sector. This three year demonstration mission will prove whether General Atomics’ weather satellite can do the job. The Space Force has also contracted with Orion Space Systems to test its own weather satellite in orbit.
For Northrop Grumman, this contract helps keep its launch business alive while it awaits a new American engine for its Antares rocket, replacing the Russian engines it has previously depended on.
Satellite fuel company Orbit Fab signs Impulse to build part of its fuel depot
The satellite fuel company Orbit Fab, which is offering a way for satellites to get refueled on a regular basis based on a firm price schedule, has selected the orbital tug company Impulse to build part of its fuel depot in advance of a demonstration refueling mission for the Space Force.
The Space Force last year awarded Orion Space Solutions a $50 million contract for the Tetra-5 experiment. Three satellites will be stationed in geostationary orbit (GEO) where Impulse Space’s Mira orbital service vehicle will serve as a hosting platform for Orbit Fab’s fuel depot. “This demonstration will pave the way for future commercial orbital refueling services, as well as additional collaborative opportunities and missions between Orbit Fab and Impulse Space,” said Barry Matsumori, chief operating officer of Impulse Space.
The Tetra-5 satellites and the fuel depot will use Orbit Fab’s refueling port known as RAFTI, or Rapidly Attachable Fuel Transfer Interface. Impulse Space will provide hosting services such as power, communications, attitude control and propulsion for the fuel depot. The Tetra spacecraft will rendezvous and dock with the depot.
If successful, this mission will prove the viability of this refueling system, and encourage other satellite manufacturers to include RAFTI on their satellites.
Betelgeuse continues to fluctuate in unexpected ways

After the star’s light dimmed for almost a year in 2019 to 2020 due to what astronomers believe was a dust cloud that was released from the star, it has continued to fluctuate differently than in the past.
Now, it is glowing at 150% of its normal brightness, and is cycling between brighter and dimmer at 200-day intervals – twice as fast as usual – according to astrophysicist Andrea Dupree of the Harvard-Smithsonian Centre for Astrophysics. It is currently the seventh brightest star in the night sky – up three places from its usual tenth brightest.
The astronomers believe the star is recovering from the ejection of material from that 2019-2020 dimming, its gas bag shape bouncing in and out like a blob of water floating in weightlessness. They also think it might take five to ten years for those reverberations to settle down.
Betelgeuse, a red giant star, is theorized to go supernovae sometime in the next 10,000 to 100,000 to a million years.
NASA’s corrupt safety panel doubts Starliner is ready for its first manned flight in July
The head of NASA’s safety panel — which over the years has consistently missed the big safety issues while whining about things that did not matter — expressed strong doubts yesterday on whether Boeing’s Starliner manned capsule is ready for its first manned flight in July.
Speaking at a May 25 public meeting of the Aerospace Safety Advisory Panel, Patricia Sanders, chair of the committee, expressed skepticism that NASA and Boeing will be able to close known issues with Starliner in time for a launch currently scheduled for as soon as July 21.
“There remains a long line of NASA processes still ahead to determine launch readiness” for the Crew Flight Test (CFT) mission, the first crewed flight of the spacecraft with two NASA astronauts on board. “That should not be flown until safety risks can either be mitigated or accepted, eyes wide open, with an appropriately compelling technical rationale.”
This panel hasn’t the faintest idea what it is talking about, and should be ignored. It appears that NASA and Boeing are presently reviewing the capsule’s parachute system. Sanders however raised other issues which actually appear more designed to simply slow or even prevent the capsule’s launch.
The panel did the same thing during the development of SpaceX’s manned Dragon capsule, making irrelevant claims about paperwork and the safety of the company’s Falcon 9 fueling procedures that were ridiculous. Meanwhile, it has ignored much more fundamental numerous safety issues with NASA’s SLS rocket and Orion capsule, such as the agency’s plan to fly it manned using its capsule environmental system for the first time.
It is very possible that there remain serious safety issues with Starliner. I simply note that I would not rely on NASA’s safety panel to provide me an honest or educated appraisal of the situation.
Vulcan launchpad static fire engine test aborted
ULA engineers were forced yesterday to abort their first attempt to complete a launchpad static fire engine test of the first stage of the company’s new Vulcan rocket due to an issue with “the booster’s ignition system.”
[D]uring the countdown at Launch Complex 41 Thursday afternoon, ULA teams “observed a delayed response from the booster engine ignition system,” the company said in a statement. The issue meant that countdown procedures ahead of the ignition of two Blue Origin-built BE-4 engines at the business end of the company’s new rocket had to be halted.
The roughly 200-foot rocket will have to be rolled back into ULA’s nearly 300-foot protective Vertical Integration Facility for technicians to assess the booster’s ignition system.
It will obviously be necessary to attempt this static fire test again before attaching the rocket’s solid-fueled side boosters, which suggests the launch’s tentative target date in June is likely threatened.
These kinds of issues are not unexpected prior to a rocket’s first launch. ULA however is now paying for the three-plus year delay imposed on it by Blue Origin’s delays in delivering the BE-4 engines used in that first stage. These pre-launch tests had been planned for 2020, not 2023. Let us hope that ULA engineers don’t rush these tests now, because of those Blue Origin delays.
Ispace publishes results of its investigation into Hakuto-R1 lunar landing failure

Orbiter (LRO). Click for original blink image.
Ispace today published the results of its investigation into the failure of its Hakuto-R1 lunar landed to touch down on the moon successfully, stating that the cause was a software error which thought the spacecraft was closer to the ground than it was.
At the end of the planned landing sequence, it approached the lunar surface at a speed of less than 1 m/s. The operation was confirmed to have been in accordance with expectations until about 1:43 a.m., which was the scheduled landing time.
During the period of descent, an unexpected behavior occurred with the lander’s altitude measurement. While the lander estimated its own altitude to be zero, or on the lunar surface, it was later determined to be at an altitude of approximately 5 kms above the lunar surface. After reaching the scheduled landing time, the lander continued to descend at a low speed until the propulsion system ran out of fuel. At that time, the controlled descent of the lander ceased, and it is believed to have free-fallen to the Moon’s surface.
The company believes the software got confused when the spacecraft crossed over the rim of Atlas Crater.
The resulting crash produced the debris seen by LRO to the right.
Virgin Galactic completes first manned suborbital flight in two years
Virgin Galactic yesterday completed its first manned suborbital flight since July 2021, carrying six employees to about fifty miles altitude for about five minutes.
Virgin Galactic’s “mothership” aircraft, VMS Eve, took off from the runway at Spaceport America in New Mexico at 11:15 a.m. Eastern. The takeoff occurred more than an hour behind a schedule provided by the company the day before, but the company did not disclose the reason for the delay.
Virgin Galactic released VSS Unity at 12:23 p.m. Eastern. The spaceplane appeared to perform a nominal burn of its hybrid rocket engine before descending to a runway landing back at Spaceport America nearly 15 minutes later. Virgin Galactic said the vehicle reached a peak altitude of 87.2 kilometers — above the 50-mile altitude used by U.S. government agencies for awarding astronaut wings, but below the 100-kilometer Kármán line — and top speed of Mach 2.94.
The company did not live stream the event, in sharp contrast to the heavy coverage it always provided when Richard Branson was in charge. It now says it soon begin regularly passenger flights.
