China sends a new crew to its Tiangong-3 space station

7:31 pm

Using its Long March 2F rocket, China today (May 30th in China) sent a new three-man crew to its Tiangong-3 space station for a five month mission.

The launch was from the Juiquan spaceport in the interior of China, so both the four side strap-on boosters as well as the core stage crashed somewhere in China. No word of any damage or injuries.

The Shenzhou capsule is expected to dock with the station about six hours after launch. The old crew’s stay will overlap with this new crew for a short time before returning to Earth.

The leaders in the 2023 launch race:

35 SpaceX
20 China
8 Russia
5 Rocket Lab

American private enterprise still leads China 40 to 20 in the national rankings, and the entire world combined 40 to 36. SpaceX alone now trials the rest of the world combined 35 to 36, but trails the entire world including American companies 35 to 41.

Cracking pedestal crater near Mars’ north pole

Cracking pedestal crater near Mars' north pole
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have also rotated it so that north is to the top.

Labeled a “terrain sample” by the camera team, this picture was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule so as to maintain its proper temperature. As usual, when the camera team needs to do this, they try to pick a target of interest. Sometimes they succeed, sometimes not.

In this case, the picture is of a location only about 800 miles from the Martian north pole, on the northern lowland plains. While the section shown to the right focuses on the largest crater, the full picture includes a few others, all of which appear to have their interior floors cracking in the same way, and all appear to be pedestal craters, sitting above the surrounding terrain, though by not as much.

China unveils next Shenzhou launch date and crew to its space station

9:07 am

China today revealed the next three-man crew to occupy its Tiangong-3 space station, with a planned launch in a Shenzhou crew capsule targeting May 30, 2023, Chinese time.

Because of time differences, that launch will occur tonight at 6:28 pm tonight, Pacific time. The rocket will be a Long March 2F taking off from China’s western interior Jiuquan spaceport. The rocket’s lower stages will therefore crash somewhere in China.

The crew will remain on board the station for five months, and with one astronaut the first Chinese to fly in space four times.

North Korea notifies Japan of orbital rocket launch; Japan and South Korea protest

8:56 am

North Korea today sent a notification to Japan’s coast guard announcing a May 31st to June 1st launch window for an orbital rocket launch aimed at placing a military reconnaissance satellite into orbit.

Japan’s coast guard said North Korean waterway authorities revealed that the launch window was between May 31 and June 11 and that the launch may affect waters in the Yellow Sea, East China Sea and east of the Philippines’ Luzon Island.

A safety warning was issued by Japan’s coast guard for ships in the area on those dates due to the possible dangers of falling debris. The coast guard coordinates and distributes maritime safety information in East Asia, which is most likely why it received North Korea’s notice.

For North Korea to launch a satellite into space, it would need to use long-range missile technology banned by U.N. Security Council resolutions. The country’s previous launches of Earth observation satellites were viewed as missile tests in disguise.

Both Japan and South Korea have protested, saying this launch would violate UN sanctions, with one Japanese official claiming that country would shoot it down if it crossed over its territory.

It is unknown if Japan has the military capability to shoot down a rocket in flight. It has never tested such technology. North Korea meanwhile has done numerous suborbital missile tests in the last two years, and has three times in the past launched small satellites into orbit, the last time in 2016.

India’s space agency ISRO launches GPS-type satellite

10:31 pm

India’s space agency ISRO today successfully used its GSLV rocket to place the first of a new constellation of that country’s second generation GPS-type satellites into geosynchronous orbit, lifting off from its Sriharikota east coast spaceport.

This was India’s fourth successful launch in 2023, matching its entire total last year. It appears that country has finally recovered from its panic during COVID.

The leader board for the 2023 launch race remains the same:

35 SpaceX
19 China
8 Russia
5 Rocket Lab

American private enterprise still leads China 40 to 19 in the national rankings, and the entire world combined 40 to 35. SpaceX alone is now tied with the rest of the world combined 35 to 35, but trails the entire world including American companies 35 to 40.

A fractured spot in Mars’ northern lowland plains

11:52 am

A fractured spot in Mars' northern lowland plains
Click for original image.

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

10:12 am

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

9:59 am

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

9:51 am

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

9:26 am

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.
