Taking Starlink on a vacation sailing trip

A Starlink subscriber to the company’s RV option decided to try it on his sailing boat during a weeklong trip among the Greek islands, and found it worked surprisingly well.

They combined Starlink’s service with cellular connectivity and compared the two while using social media, Google maps, and video streaming. The outcome? Starlink and cellular complimented each other, according to Topolev.

Starlink suffered outages when it was surrounded by other boats’ masts or when the yacht made sharp turns, but worked well at sea, whereas cellular connectivity dropped out when the boat was far from the shore, Topolev said. “It was surprisingly good,” he said. “There were some outages and sometimes we had to manually reboot it … but basically it worked … almost all the time.”

The RV option is specifically for use in moving vehicles, though its use on a boat was not expected to be its prime target customers. Nonetheless, the test suggests strongly that Starlink will work quite well on the big cruise ships, one liner of which, Royal Caribbean, has already signed a deal to make Starlink operational by next year.

Ingenuity’s flight plan for its next and 31st flight

Perseverance's location on September 2, 2022
Click for interactive map

The Ingenuity engineering team today released the flight plan for the helicopter’s next flight on Mars, its thirty-first since arrival.

The flight is scheduled for no earlier than September 6, mid-day on Mars, and will travel about one minute to the west for a distance of about 319 feet. The white dot on the overview map to the right shows the approximate landing spot, with the green dot marking Ingenuity’s present position. The blue dot marks Perseverance’s present position as it moves to the south and west after leaving the first delta cliff face it studied during the past few months.

The flight’s main goal is to reposition the helicopter to keep it close to the rover to facilitate communications. However, the engineering team has also now adjusted its goals to also practice hitting very precise landing spots. This goal is to develop the engineering and software that can be used on the helicopter that is not yet built that NASA and ESA intend to use to recover Perseverance’s core samples for return to Earth. That helicopter will not only have to very precisely land right next to those samples in a position allowing it to grab them, it must also land very precisely next to the sample return spacecraft to deposit them within it.

China’s Long March 4C rocket launches military satellite

China today successfully used its Long March 4C rocket to place a military Earth observation satellite into orbit.

Launched from an interior spaceport, the rocket’s lower stages thus crashed uncontrolled in China.

The leaders in the 2022 launch race:

39 SpaceX
34 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 54 to 34 in the national rankings, and the entire globe 54 to 52.

OneWeb lost $229 million when Russia canceled its launches and confiscated its satellites

On September 1, 2022, OneWeb revealed that Russia’s cancellation of the last six or so OneWeb launches as well as Russia’s confiscation of 36 satellites cost the company $229 million.

Russia’s actions were the response by then head of Roscosmos, Dmitry Rogozin, to sanctions imposed on Russia by the west because of its invasion of the Ukraine. Rogozin’s petty response ended up shooting his space agency in the foot, because it ended up losing billions of dollars in foreign launch business, business that is not likely to return for decades.

OneWeb has since signed contracts with SpaceX, ISRO (India’s space agency), and Relativity for future launches. None of these have been firmly scheduled, though the first by SpaceX is tentatively planned for sometime before the end of the year.

SLS test launch scrubbed again

NASA engineers once again were forced to scrub the launch of the SLS rocket today due to another hydrogen leak during fueling.

The launch director waived off todayโ€™s Artemis I launch attempt at approximately 11:17 a.m. EDT. Teams encountered a liquid hydrogen leak while loading the propellant into the core stage of the Space Launch System rocket. Multiple troubleshooting efforts to address the area of the leak by reseating a seal in the quick disconnect where liquid hydrogen is fed into the rocket did not fix the issue.

NASA has one more chance, on September 5th, to launch this rocket before it must return it to the assembly building to replace the flight termination batteries, used to abort the launch after liftoff should something go seriously wrong during flight. As I understand it, their use-by date is September 6th, and it would require a major safety waiver by the military range officer, who is entirely independent from NASA and under no obligation to it, to allow for a launch after that date with those batteries.

September 2, 2022 Quick space links

The tweet however provides no date for the test, nor any information about this particular engine itself.

This is preliminary design work involving Earth-based tests. A later phase, not yet awarded, will move on to orbital tests.

Most of this new private capital apparently came from Saudi Arabia and Greece, and the constellation will start out focused on serving those regions as well as Luxembourg.

Sunspot update: Solar activity continues to exceed sunspot predictions

It is the beginning of September and time to post another update on the Sun’s ongoing solar cycle. Below is NOAA’s monthly graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, with the activity in August now added. I have also added some additional details to the graph to give the numbers a larger context.

Though sunspot activity dropped in August it remained significantly above the predictions of the panel of government solar scientists put together by NOAA. The predicted sunspot number for August, as indicated by the red curve, was supposed to be about 48. The actual number was 75.

Pushback: Maine parent wins lawsuit against school board for attempting to ban him

lawsuit against him. Click for video from which this image was captured.

Bring a gun to a knife fight: Shawn McBreairty, a Maine parent who had repeatedly challenged two different local school districts, including his own, for their efforts to teach the queer agenda to little children, yesterday won a $40K settlement from one of those school boards, Regional School Unit #22, after a court judge had ruled that the board’s actions to ban and censor McBreaity clearly violated his first amendment rights.

This is an update of an earlier August 1, 2022 blacklist column. Because McBreairty had tried to read aloud at a board meeting the pornography contained in several books that the school board had approved for its school children, he was silenced, then banned from attending school board meetings, both in person and virtually, for the next eight months.

When the judge ruled entirely in McBreairty’s favor, issuing a temporary injunction against the school board’s actions, the board clearly recognized its case would not hold up in court, and it chose to settle, paying $40K for McBreairty’s legal fees. As the judge noted in her decision:

Chinese astronauts complete first spacewalk using new Wentian module

The new colonial movement: Chinese astronauts yesterday completed their first spacewalk using the airlock on the new Wentian module that was recently launched to that nation’s Tiangong-3 space station.

The spacewalk lasted six hours, and was mostly designed to test the airlock itself as well as do the first tests of Wentian’s own robot arm. It appears they also installed an “extended pump set”, whatever that is, and did other work near the hatch. More here.

NASA is paying Boeing twice as much as SpaceX for its manned flights

Capitalism in space: in an excellent analysis of the total amount NASA will pay both SpaceX and Boeing for all their manned flights to ISS before the station retires, Eric Berger at Ars Technica has determined that the agency will essentially pay Boeing twice as much per flight.

In 2014, NASA narrowed the crew competition to just two companies, Boeing and SpaceX. At that time, the space agency awarded Boeing $4.2 billion in funding for development of the Starliner spacecraft and six operational crew flights. Later, in an award that NASA’s own inspector general described as “unnecessary,” NASA paid Boeing an additional $287.2 million. This brings Boeing’s total to $4.49 billion, although Finch told Ars that Boeing’s contract value as of August 1, 2022, is $4.39 billion.

For the same services, development of Crew Dragon and six operational missions, NASA paid SpaceX $2.6 billion. After its initial award, NASA has agreed to buy an additional eight flights from SpaceXโ€”Crew-7, -8, -9, -10, -11, -12, -13, and -14โ€”through the year 2030. This brings the total contract awarded to SpaceX to $4.93 billion.

Since we now know how many flights each company will be providing NASA through the lifetime of the International Space Station, and the full cost of those contracts, we can break down the price NASA is paying each company per seat by amortizing the development costs.

Boeing, in flying 24 astronauts, has a per-seat price of $183 million. SpaceX, in flying 56 astronauts during the same time frame, has a seat price of $88 million. Thus, NASA is paying Boeing 2.1 times the price per seat that it is paying SpaceX, inclusive of development costs incurred by NASA.

Despite the larger payments to Boeing, the company could very well lose money on Starliner. The higher cost to NASA from Boeing is due almost entirely because the agency was absorbing more of its initial development cost. SpaceX’s Dragon capsule had already been flying cargo missions to ISS when these manned contracts were awarded. SpaceX merely had to upgrade its manned capsule. Boeing had to design and build it from scratch. Moreover, the contracts were fixed price, which means Boeing had to absorb more than a half billion in additional costs when it had to refly the unmanned demo flight of Starliner.

Finally, because of the delays, Boeing won less NASA business. It also has gotten none of the private commercial manned flights that are going on right now. Those contracts went to SpaceX, including all the profits. Whether Boeing can eventually win some private contracts down the road is unknown. It will certainly have to lower its price to compete with SpaceX.
