The private weather industry moves forward

Link here. Key quote:

Early next month, aerospace start-up Spire Global of Glasgow, UK, will send a mini-satellite into space aboard an Indian government rocket. This ‘cubesat’ will join 16 others that are beaming a new type of atmospheric data back to Earth — and some scientists worry that such efforts are siphoning funding away from efforts to push forward the science of weather forecasting. Spire will begin providing observations to the US government on 30 April.

The probes track delays in radio signals from Global Positioning System (GPS) satellites as they pass through the atmosphere — a technique known as radio occultation. Researchers can use the data to create precise temperature profiles of the atmosphere to feed into weather-forecasting models — and eventually, perhaps, climate models.

Spire and its competitor GeoOptics of Pasadena, California, are participating in a pilot project announced in September by the US National Oceanic and Atmospheric Administration (NOAA), which is under pressure from the US Congress to determine whether it can cut costs by using commercial weather data. But scientists worry that such efforts are hampering the development of radio occultation. For years, they have sought federal funding for a project to advance the technique, but Spire and its competitors say they can offer high-quality data for a fraction of the price. [emphasis mine]

The quotes I have highlighted illustrate the hidebound leftist scientific opposition to introducing private enterprise into weather research. The article, published in the journal Nature, never once articulates in any way how these private efforts will hurt scientific research. What it does show is that the private effort will cost a tenth of the government effort while getting launched much faster. The money, however, will go to these private companies, and not the scientific factions that up until now have lived on the government money train.

The complaints here are the same as those I saw in NASA back about a decade ago when NASA first considered hiring private companies to provide it cargo to ISS. This is a turf war. NOAA is now being pressured by Congress to do the same: stop building big expensive weather satellites and buy the service for much less from the private sector. The scientific community sees this as a threat to its funding and is trying to stop it.

With Republicans controlling all three branches of the federal government I think this opposition will be fruitless, and we shall see the shift to private enterprise in weather data-gathering to accelerate.

Government-owned Alaska Aerospace considers second spaceport

The competition heats up: State-owned Alaska Aerospace is considering opening a second spaceport outside the state and closer to the equator.

Alaska Aerospace operates the Pacific Spaceport Complex Alaska. The Kodiak Island complex is capable of polar, sun-synchronous and high-inclination orbits, but does not support the equatorial launches that make up most of the industry demand. With the new launch facility, Campbell said having equatorial launches will give the corporation a competitive advantage and also bring more customers to Kodiak.

The state no longer funds the corporation, which has never made money. Still, it now has contracts with Rocket Lab and Vector Space Systems and this new move is an obvious effort to make itself more viable.

Recovered Falcon 9 first stage prepped for launch

The competition heats up: SpaceX on Tuesday revealed that last week it has completed the standard static fire testing of the recovered Falcon 9 first stage that it plans to relaunch in March.

A March launch would mean an 11-month turnaround, which is far from optimal, but understandable for the first time. SpaceX’s founder and chief executive, Elon Musk, has acknowledged the company must do better in the future if resuable flight is to become economically viable. He says the next—and likely final—iteration of the Falcon 9 rocket will be optimized for reuse. “Block 5 is the final upgrade of the Falcon architecture,” he tweeted earlier this year. “Significantly improves performance & ease of reusability. Flies end of year.”

It now seems likely that SpaceX will fly the landed boosters it currently has, at most once or twice, before retiring them, instead of multiple times. Although the company hasn’t elaborated on the problems with the engines, booster structure, or composite materials that have shown wear and tear after their orbital launches and returns, Musk is confident that changes to the Block 5 version of the rocket will solve the problem. “I think the F9 boosters could be used almost indefinitely, so long as there is scheduled maintenance and careful inspections,” he has said.

In other words, SpaceX has had — for the first time in history — the opportunity to inspect a number of used first stage rockets, and that precious knowledge is making it possible for them to upgrade the stage design to make future stages more hardy. In fact, those future stages won’t be stages, but reusable vessels that SpaceX could even name if it wished.

SpaceX to double leased space at Los Angeles port

The competition heats up: SpaceX has requested a doubling of its leased space the port of Los Angeles in order to facilitate the return of first stages launched from Vandenberg.

The Board of Harbor Commissioners will vote at its Thursday morning meeting on a deal to enlarge Space Exploration Technologies Corp.’s footprint at San Pedro’s outer harbor. The company hopes to lease 4.6 acres of land and water area along Berths 51 to 53 for $23,735 a month, plus insurance and any incidental costs.

In addition to extra space, the lease agreement allows the company to have berthing rights, install a chain-link fence around the property, build a concrete rocket-support pedestal, and add an office trailer, guard shack and portable restrooms, according to a staff report prepared for the commission.

According to the article, the increased space is needed because of the company’s plans to launch every two weeks from its pads at Kennedy and Vandenberg.

A review of 2016 launches

Link here. The report essentially confirms my own conclusions that I posted several weeks ago. This new report however also looks at total payloads, something I had not done, and finds that though there was a decline in 2016 in the number of satellites launched, they expect that trend to end in 2017 with the continued growth in the smallsat industry.

India to launch spare GPS satellite because of single satellite failure

Because of the failure of the atomic clocks on one of its GPS satellites have failed, India now plans to launch one of their spare satellites to increase the system’s redundancy.

The article does not say whether they will make any changes to the clocks on the spare satellite, which are the same as the failed clocks on the Indian satellite and were all built by the same European company that built the clocks on Europe’s Galileo GPS satellites that are also failing.

Next Falcon 9 launch delayed as SpaceX rearranges manifest

Because the launchpad at Kennedy is not quite ready for the planned February 3 launch of a commercial satellite, SpaceX has rearranged its launch manifest to switch that launch with the next Dragon mission to ISS, essentially delaying their next launch by two weeks.

With [launchpad] 39A still not ready to debut in its new role with SpaceX, the first mission set to launch from this pad – the Falcon 9 launch with EchoStar 23 – was pushed to the right a number of times. Although 39A is very close to being ready to conduct launches, EchoStar 23’s launch date was deemed to be too close to the mid-February target for the CRS-10 Dragon mission.

SpaceX and NASA discussed the situation on Friday night, before deciding it would be prudent to place EchoStar 23’s launch after CRS-10, allowing engineers to finalize modification and checkout work on the famous pad and simultaneously avoid a potential delay to the important Dragon mission to the Station.

The real problem here is that SpaceX had planned to have two working launchpads by this time, but doesn’t because their first pad was damaged in the September 1 Falcon 9 launchpad explosion. The consequences is that, for at least the next month, they will not be able to set a pace of a launch every two weeks.

Soyuz launches successfully from French Guiana

A Russian Soyuz rocket, built for Arianespace and launched from French Guiana, successfully placed a commercial satellite in geosynchronous orbit on Friday.

The launch has some significance. First, it was the first time a Soyuz rocket placed a payload into geosynchronous orbit. Second, the payload was the first satellite built by a German company in more than 25 years

Finally, and most important, it demonstrated that at least one configuration of the Soyuz rocket is still operational as Russia investigates the corrupt practices at the company that has been building upper stage engines for both its Soyuz and Proton rockets.

Update: Russia has revealed that this on-going investigation will now delay the next Proton rocket launch for 3.5 months. This means that launch will occur sometime in May, and will occur just weeks short of a full year after the last Proton launch on June 9, 2016.

Making a Linux laptop

Yesterday while I was sitting at my desk working on my Linux desktop computer, I got a phone call from someone from “Windows Technical Support.” The man on the line said to me, quite nicely, that they had noticed a problem with my computer and wanted to help me fix it.

I said, “You are talking about my Windows desktop computer, the one I am working right now, correct?”

The man said sweetly, “Yes, sir. That’s the computer we have seen a problem with.”

I answered sweetly, “I just want to be sure, so let me ask again. You are referring to the Windows computer in front of me, the one on my desk?”

He responded, “Yes sir. Could you press your start menu please and go to settings?”

Unfortunately, I had too much work to do, and couldn’t spend more time with him. I would have liked to have led him along for as long as possible, but simple didn’t have the time. Instead, I said, “Um, I can’t really go to my Windows settings because my desktop is a Linux computer, and has been for a decade. Have you heard of Linux?”

Instantly the phone went dead.

I tell this tale because it is only one more reason I abandoned Windows back in 2006. With Linux I have no viruses to worry about, and scammers like this can’t do me any harm.

Anyway, this post really isn’t about Windows scammers. Instead, I want to relate my experience this past week in setting up my first Linux laptop, following the step-by-step instructions provided by James Stephens and posted here on Behind the Black last year in the following series:
