Vreemde lichtgevende bol gespot boven België (en daar zit ene Elon Musk vermoedelijk voor iets tussen)


Op verschillende plaatsen in ons land hebben mensen gisterenavond een vreemd lichtgevend fenomeen in de lucht zien verschijnen. Kort na 18 uur vloog hij plots gezapig tussen de wolken: een vreemde, heldere bol.

De meldingen komen onder meer uit Anderlecht, Tubeke, Zwalm, Moorslede, Wevelgem, Poperinge, Rochefort, ... Ook in Frankrijk zagen mensen de opmerkelijke verschijning passeren, onder meer in Lyon, Annecy en Grenoble. “Er flikkerde niks, het licht was constant. En toen begon het traag te bewegen en verdween het weer”, verklaart een getuige aan RTL Info. De vorm? Net een lamp. “Het was een vreemd licht in de vorm van een bewegende zaklamp”, stelt iemand. “Een bal in de lucht met een grote lamp aan”, voegt een ander toe.



Starlink

Hoewel er nog geen officiële verklaring is voor de vliegende lamp boven ons land, is het zeer waarschijnlijk dat het Amerikaanse ruimtebedrijf SpaceX van Elon Musk er een en ander mee te maken heeft. Gisteren lanceerde SpaceX immers een tweede cluster van mini-satellieten voor zijn toekomstige constellatie ‘Starlink’, dat wereldwijd supersnel internet moet leveren (dus ook op bijvoorbeeld afgelegen locaties waar internet normaal totaal afwezig, onbetrouwbaar of duur is).

De satellieten – die zo’n 227 kilo per stuk wegen – worden telkens per zestig gelanceerd. Daarna komen ze op ongeveer 550 kilometer hoogte in de atmosfeer terecht: hoger dan het ISS, maar lager dan de meeste andere satellieten.

Door een supersnel graantje mee te pikken op de globale internetmarkt hoopt SpaceX-topman Elon Musk mee de ontwikkeling van zijn raketten en ruimteschepen – op naar Mars, weet u wel – te helpen financieren.

Het ruimtebedrijf heeft tot dusver toelating gekregen om 12.000 satellieten te lanceren voor het Starlink-breedbandinternet, gespreid over verschillende ruimtebanen. Intussen heeft SpaceX frequenties aangevraagd voor nog eens 30.000 kunstmanen bovenop die 12.000. En dat is niet zonder controverse. Er wordt gevreesd voor overbevolking van satellieten in lage banen met risico op botsingen en verstoring van sterrenkundige waarnemingen.

De Falcon 9-raket met opnieuw zestig satellieten aan boord schoot gisterenmiddag in ieder geval zonder incidenten de lucht in vanuit Cape Canaveral in Florida. Ook na de eerste lancering in mei dachten verschillende mensen dat ze ufo’s hadden gespot.

NASA report finds Boeing seat prices are 60% higher than SpaceX

On Thursday, NASA's inspector general released a report on the space agency's commercial crew program, which seeks to pay Boeing and SpaceX to develop vehicles to transport astronauts to the International Space Station.

Although the report cites the usual technical issues that the companies are having with the development of their respective Starliner and Dragon spacecraft, far more illuminating is its discussion of costs. Notably, the report publishes estimated seat prices for the first time, and it also delves into the extent that Boeing has gone to extract more money from NASA above and beyond its fixed-price award.

Boeing's per-seat price already seemed like it would cost more than SpaceX. The company has received a total of $4.82 billion from NASA over the lifetime of the commercial crew program, compared to $3.14 billion for SpaceX. However, for the first time the government has published a per-seat price: $90 million for Starliner and $55 million for Dragon. Each capsule is expected to carry four astronauts to the space station during a nominal mission.



What is notable about Boeing's price is that it is also higher than what NASA has paid the Russian space corporation, Roscosmos, for Soyuz spacecraft seats to fly US and partner-nation astronauts to the space station. Overall, NASA paid Russia an average cost per seat of $55.4 million for the 70 completed and planned missions from 2006 through 2020. Since 2017, NASA has paid an average of $79.7 million.

Beyond these seat prices, Inspector General Paul Martin's report also notes that Boeing received additional funding from NASA, above and beyond its fixed-price award.

“Not consistent”
"We found that NASA agreed to pay an additional $287.2 million above Boeing’s fixed prices to mitigate a perceived 18-month gap in ISS flights anticipated in 2019 and to ensure the contractor continued as a second commercial crew provider, without offering similar opportunities to SpaceX," the report states.

According to Martin, who had extensive access to NASA officials in the preparation of the report, Boeing in 2016 proposed pricing for its third through sixth crewed missions using the "single 2016 mission price," which was substantially higher than NASA and Boeing had originally agreed upon. In response to this, NASA's Office of Procurement determined this was "not consistent with the terms of the contract and did not match the contract’s fixed-price table."

However, Boeing continued to press NASA for additional funding. After "prolonged negotiations," according to Martin, Boeing offered some benefits to NASA, such as reduced lead times before the missions and a variable launch cadence. NASA then agreed to pay the additional $287.2 million for these four missions, which are likely to fly in the early 2020s.

Perhaps the most striking rationale for approving the additional funds was that Boeing may have discussed backing out of the commercial crew program (CCP). Martin writes, "According to several NASA officials, a significant consideration for paying Boeing such a premium was to ensure the contractor continued as a second crew transportation provider. CCP officials cited NASA’s guidance to maintain two US commercial crew providers to ensure redundancy in crew transportation as part of the rationale for approving the purchase of all four missions at higher prices."

A spokesman for Boeing, Josh Barrett, denied that Boeing had threatened to end its commercial crew participation. "Boeing has made significant investments in the commercial crew program, and we are fully committed to flying the CST-100 Starliner and keeping the International Space Station fully crewed and operational," he told Ars.

The report notes that as NASA was agreeing to pay Boeing extra for these benefits, a similar deal was not offered to SpaceX. "In contrast, SpaceX was not notified of this change in requirements and was not provided an opportunity to propose similar capabilities that could have resulted in less cost or broader mission flexibilities," Martin writes.

Het ziet ernaar uit na een discussie tussen Musk en Tim Dodd op Twitter dat MK1 wordt afgeschreven en men aan de gang gaat met Mk3 in Boca Chica.

quote:

Ok, more rumors, this time from SpaceX Boca Chica Facebook group:

RUPTURE UPDATE:
Through back channels it has been revealed that MK1 suffered an accidental overpressure to failure. Fuel and oxidizer would typically be loaded to 3 Bar or 43.5 psi~ for densification purposes and flightworthy tanks may be tested to 1.5-2x that value for single time structural proofing. In the case of what happened today the story is that communications errors between the pumps/sensors and remote controls allowed the tanks to be massively and erroneously overpressured to the point of failure, leading to catastrophic rupture.
We expect SpaceX in good time to reveal the details, they may explain it was deliberate as big changes in airframe and control surfaces in the succeeding MK series variants are coming.

quote:

In that case, it sounds like although this was technically accidental (perhaps retconned by the PR folks), the structural engineers and welding teams who worked on Mk1 have reason to be really happy about it turned out. A test-to-failure that held up until the tanks were "massively and erroneously overpressured" would seem to strongly validate that their approach to designing and fabricating the structures was sound.

The pumps/sensors and remote controls folks are probably not so happy about this. (Although it did show them a failure mode in their design, which as many have noted here, is worth more to an engineer than ten flights without issue.)

Waarschijnlijk omdat ze dit al zagen aankomen, of niet; geen officieel antwoord dus het is het één of ander. Maar goed veel geleerd en Mk2 is nog in aanbouw en ik denk dat ze volgend jaar Q1 een heel eind zijn met Mk3.

Ik gok April voor eerste flight tests Mk3.
