Stratolaunch airplane nears first flight

On Jan 9, the giant Stratolaunch plane did a taxi test that reached a top speed of 219 kilometers per hour (137 mph), and the nosewheel rotated off the ground. Flight tests probably aren’t far off.

I remain a little baffled about the business plan for Stratolaunch, especially since the initial payload is apparently supposed to be *three* Pegasus XL launch vehicles. That eems an odd thing to do. But Stratoluanch intends to eventually build their own better-optimized expendable and reusable launch vehicles. And the more launchers, the better.

Two pieces of NASA-marked (but likely not NASA-produced) concept art from the 1960’s depicted artificial-G space stations.

 

The first station (previously presented here in black and white not so long ago) depicts a substantial three-armed station witha multi-segment spine and three habitats. At one end of the spine is a nuclear reactor and its radiator; at the other end is a presumably rotationally0decoupled docking section. There is also an external “track” with two cars seemingly to provide transport from one habitat to another; it doesn’t really seem like this would provide a substantial improvement in transport over simply taking an elevator from one hab up to the spine and then down another elevator to the destination hab.

This space station, which appears from the art style to be a Grumman design, is a single-launch space station to be launched atop a Saturn V. The two arms would fold back for storage on the launch vehicle and would deploy once in orbit. An Apollo CSM is shown approaching for docking along the centerline; it’s not clear if the docking cone was rotationally decoupled. if it was not, the two Apollo-like capsules hanging off the sides of the cone are a bit of a head scratcher.

Both renderings have been uploaded in their full resolution to the 2019-01 APR Extras dropbox folder. This folder is available to APR Patreon Patrons and APR Monthly Historical Documents Program subscribers at the $4 per month level and above.

Honestly, I thought the season premiere, “Ja’loja,” was pretty lackluster (caveat: saw that during my so-sick-I’m-an-NPC phase). But the second episode, “Primal Urges,” shows a vast improvement. There was a whole lot of cringeworthy squidginess – I could’ve gone my whole life without all that hot Moclan-on-Moclan action – but even that served the story. And there were some great lines that are exactly the sort of thing you’ve never hear on *any* version of Trek… “Hi, I’m Dan” and “Aw, neat, what is it” don’t sound like much out of context, but they made me laugh uproariously *in* context. Plus, the episode just *looked* downright great: TNG *wishes* they could have done half as well back in the day. Interestingly, this second episode of season 2 was originally supposed to be the final episode of season 1, but for whatever reason it got slotted in here.

I have high hopes for the rest of the season. I do miss Yaphit, and hope he’s in this season.

NASA’s New Horizons Mission Reveals Entirely New Kind of World

This image taken by the Long-Range Reconnaissance Imager (LORRI) is the most detailed of Ultima Thule returned so far by the New Horizons spacecraft. It was taken at 5:01 Universal Time on January 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers), with an original scale of 459 feet (140 meters) per pixel.

This indicates that higher-rez images are possible in the coming days… assuming the camera was pointed in the right direction. Unlikely that it wasn’t, but you never know.

The first color image of Ultima Thule, taken at a distance of 85,000 miles (137,000 kilometers) at 4:08 Universal Time on January 1, 2019, highlights its reddish surface. At left is an enhanced color image taken by the Multispectral Visible Imaging Camera (MVIC), produced by combining the near infrared, red and blue channels. The center image taken by the Long-Range Reconnaissance Imager (LORRI) has a higher spatial resolution than MVIC by approximately a factor of five. At right, the color has been overlaid onto the LORRI image to show the color uniformity of the Ultima and Thule lobes. Note the reduced red coloring at the neck of the object.

 

And because this is 2019 and we can’t have anything nice, the Twitter maniacs and SJW scolds are at it again:

NASA Has A Bit Of A Nazi Problem With Its ‘Ultima Thule’ Name

The New Horizons probe will zip past the small Kuiper Belt object “Ultima Thule” at abut 12:30 AM eastern time (10:30 PM Mountain). NASA TV should cover it, but there’s also Ye Olde Interwebs:

How to Watch New Horizons’ Ultima Thule Flyby on New Year’s Day: A Webcast Guide

Given the distance and the consequent low data rate, I don’t imagine images will be forthcoming. Those will probably trickle in over the subsequent days, assuming the probe survives. Even now Ultima Thule appears as just a single pixel, but the light curve has been sufficiently puzzling that one explanation has been that it is surrounded by a cloud of particles or micro-moons. Which would be awesome, so long as New Horizons doesn’t hit one of them.

35 years ago, Isaac Asimov was asked by the Star to predict the world of 2019. Here is what he wrote

Like the headline says, famed science fiction author Asimov was asked at the end of 1983 to predict waht 2019 wouldbe like. He touched on three main topics:

1: Nuclear war.

2: Computers

3: Space

As to #1, he didn;t have much to say other than, effectively, if it happens, we;ll be toast and all predictions go out the window.

As to #2, he correctly – and for 1983, unsurprisingly – predicted that computers would be very important, and that computerization would have led to substantial changes in the workforce. He also said this, which would by modern standards get him labeled a Nazi:

Those who can he retrained and re-educated will have been: those who can’t be will have been put to work at something useful, or where ruling groups are less wise, will have been supported by some sort of grudging welfare arrangement.

Claiming that nanny states are less wise?? OUTRAGE!!!

But where he sadly failed utterly was in predicting the future of spaceflight.

By 2019, we will be back on the moon in force. There will be on it not Americans only, but an international force of some size; and not to collect moon rocks only, but to establish a mining station that will process moon soil and take it to places in space where it can be smelted into metals, ceramics. glass and concrete — construction materials for the large structures that will be put in orbit about the Earth.

Yeah… no. This is of course what *should* have happened, but clearly it did not. He also suggested that solar power satellites would be under construction, manufacturing industries would be setting up in orbit and that there would be important space-based observatories. Of these, only the latter came close to truth, with the Hubble fundamentally expanding humanities view of the universe. But in 1983 the Hubble was well underway and was well know, so that was no great prognostication. Additionally, the Hubble is old and creaky, close to death, with no replacement due until the Webb telescope is launched… whenever the hell it gets launched.

By 2019, the first space settlement should be on the drawing boards; and may perhaps be under actual construction.

Sigh.

Predicting the future, even relatively short-term futures, is damned difficult to do even for the best science fiction authors (and even harder for people who don’t understand science, technology and history). I can remember 1983, and can assure you confidently that virtually *nobody* would have expected that well under a decade later the Soviet union would not only have disappeared, but done so *peacefully.* Surely nobody in 1983 would have been able to predict that credit card companies would be on the leading edge of shutting down the whole concept of free expression; that astrology and related bunk would be in ascendance; that after the triumph of the freemarket over communism,hat communism would be popular enough that advocates of it would achieve high office in the US; that we’d all carry semi-intelligent supercomputers in our pockets that allow worldwide low cost video telephony and provide instant access to the sum of human knowledge, and would somehow still lead humanity to a doom of dumbth.
