The Soviet Space Station Program: From Military Satellites To The ISS

May 15, 2023 by 7 Comments

When the Space Race kicked off in earnest in the 1950s, in some ways it was hard to pin down where sci-fi began and reality ended. As the first artificial satellites began zipping around the Earth, this was soon followed by manned spaceflight, first in low Earth orbit, then to the Moon with manned spaceflights to Mars and Venus already in the planning. The first space stations were being launched following or alongside Kubrick’s 2001: A Space Odyssey, and countless other books and movies during the 1960s and 1970s such as Moonraker which portrayed people living (and fighting) out in space.

Perhaps ironically, considering the portrayal of space stations in Western media, virtually all of the space stations launched during the 20th century were Soviet, leaving Skylab as the sole US space station to this day. The Soviet Union established a near-permanent presence of cosmonauts in Earth orbit since the 1970s as part of the Salyut program. These Salyut space stations also served as cover for the military Almaz space stations that were intended to be used for reconnaissance as well as weapon platforms.

Although the US unquestionably won out on racing the USSR to the Moon, the latter nation’s achievements granted us invaluable knowledge on how to make space stations work, which benefits us all to this very day.

Mark Your Calendars, NASA Is Holding A Public Meeting On UFOs

May 15, 2023 by 22 Comments

We’re sorry, the politically correct term these days is “unidentified anomalous phenomena” (UAP), as it’s less likely to excite those with a predilection for tinfoil hats. But whether you call them flying objects or anomalous phenomena, it’s that unidentified part that has us interested.

Which is why we’ll be tuned into NASA TV at 10:30 a.m. EDT on May 31 — that’s when the agency has announced they’ll be broadcasting a meeting of an independent study team tasked with categorizing and evaluating UAP data. The public can even submit their own questions, the most popular of which will be passed on to the team.

Before you get too excited, the meeting is about how NASA can “evaluate and study UAP by using data, technology, and the tools of science”, and the press release explains that they won’t be reviewing or assessing any unidentifiable observations. So if you’re hoping for the US government’s tacit acknowledgment that we’re not alone in the universe, you’ll probably be disappointed. That said, they wouldn’t have to assemble a team to study these reports if they were all so easily dismissed. As always, interstellar visitors are dead last on the list of possible explanations, but some cases have too much hard evidence to be dismissed out of hand. They might not be little green men, but they are something.

Zippy Plastic Welding

May 15, 2023 by 53 Comments

Plastic welding isn’t a new idea. But a recent video from [The Maker] shows an interesting twist. Given a broken piece of plastic, he secures it together with tape, machines out a channel around the cracks, and then melts zip ties into the channels. Honestly, although he mentions plastic welding and soldering, we aren’t sure this isn’t just simple gluing, but it did give us some ideas. Watch the video below and you’ll probably get the same ideas.

The ingenuity here isn’t necessarily using hot plastic to glue together two pieces — that’s just a hot glue gun, after all. Rather, it occurred to us that the key here was machining out the places where significant amounts of the hot plastic could bond the two pieces together. He cut the channels with a rotary tool, buffed them, and used a hot knife to give them some internal texture. But with a 3D printer, you could build these channels into parts that were made to interlock.
