SpaceX software team talks up Starlink satellites

SpaceX’s Starlink satellite constellation is still deep into testing mode, but it’s already generating 5 trillion bytes of data on a daily basis and getting software updates on a weekly basis.

Those are a couple of the nuggets coming from a weekend Reddit “Ask Me Anything” session featuring SpaceX’s software team.

The main focus of the online chat was SpaceX’s successful mission sending NASA astronauts Bob Behnken and Doug Hurley to the International Space Station in a Crew Dragon capsule — but one of the team members, Matt Monson, has moved on from Dragon to take charge of Starlink software development.

Although SpaceX’s HQ is in Hawthorne, Calif., most of the work relating to the Starlink satellites is being done at the company’s facilities in Redmond, Wash.

SpaceX tends to play its satellite cards close to the vest, in part because the process of building a satellite system is “highly proprietary” — as one of the company’s vice presidents, Patricia Cooper, said in a 2016 filing with the Federal Communications Commission. For that reason, any nuggets about Starlink’s workings are avidly sought by SpaceX’s fans as well as the occasional inquiring journalist.

How will protests affect the pandemic?

Epidemiologists say the crowding conditions associated with mass protests over police violence seem likely to add dozens of people, or perhaps even hundreds, to the daily death toll from coronavirus infections.

But they acknowledge that that these sorts of assessments involve a tradeoff between public health and social justice.

“Racism and state-sponsored violence are critical public health issues,” Trevor Bedford, a computational biologist at Seattle’s Fred Hutchinson Cancer Research Center, wrote in a weekend string of tweets. “We should also acknowledge that the specific action of large-scale public protest at this moment during the COVID-19 pandemic may result in perhaps more than 10 but less than 100 deaths per day.”

In response to feedback, Bedford later revised his estimate to “a highly speculative” guess of more than 50 but less than 500 extra deaths for each day of protest.

Bedford and other coronavirus trackers pointed out that the protests are coming amid widespread relaxation of strict rules on social distancing and business activities. That will make it all the more difficult to tease out the specific causes behind what’s likely to be an upswing in infections.

“The protests and potential to transmit virus are on a background of general societal opening,” Bedford said. “It feels as though we’ve largely given up on controlling the epidemic and have resigned ourselves to living alongside it.”

Vaccine veterans survey the path to pandemic’s end

A public-private partnership called Operation Warp Speed is aiming to get multiple vaccines approved by the end of the year to protect against COVID-19 — but two veterans of the vaccine development process say there’s a long road ahead, with no wormholes in sight to reduce the travel time.

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said this week that there should be a “couple hundred million doses” of vaccines available by the start of next year.

That’s an ambitious timetable, according to John Mascola, head of NIAID’s Vaccine Research Center; and Larry Corey, a virologist at Seattle’s Fred Hutchinson Cancer Research Center.coron

“I don’t think either John or I are particularly happy with Tony telling everybody that it’s here by January, but if everything goes well, that’s definitely possible,” Corey said today during a webcast presented by Fred Hutch.

An online advertisement that plays off last weekend’s historic crewed SpaceX launch to boost President Donald Trump’s re-election campaign drew a protest from the wife of one of the astronauts today — and soon afterward, the campaign deleted its version of the ad.

REDMOND, Wash. — Wanna buy a used thermal vacuum chamber?

If you have a sudden yen to replicate outer-space conditions, it behooves you to check out today’s online-only auction of the hardware left over from Planetary Resources, the Redmond venture that aimed to create a trillion-dollar asteroid mining industry.

But don’t delay: By this evening, everything — from the 10-foot-tall vacuum chamber in the first-floor machine shop, to the dozens of laptops and chairs spread out in the second-floor workspace, to the satellite dish on top of the office building in Redmond — will have gone electronically to the highest bidders.
