On July 13, 1969, Apollo 11’s Saturn V sat on launchpad 39A at Cape Canaveral. The pre-launch countdown was already underway though the actual final countdown wouldn’t start for another day and a half. Nevertheless, there was plenty of activity buzzing around the Cape, but the big news in space that day wasn’t the impending manned lunar landing attempt. It was Luna 15, the Soviet mission that would reach the Moon while Apollo 11 was in orbit.

How Apollo Astronauts Didn’t Get Lost Going to the Moon

Driving, say, to a friend’s house, we usually have directions to follow like “turn left at the light then it’s the third door on the right.” The same isn’t true when going to the Moon; there are no signposts guiding the way. So how exactly did Apollo astronauts know where they were going when they went to the Moon?

Hal Laning: The Man You Didn’t Know Saved Apollo 11

By Amy Shira Teitel | May 23, 2019 12:00 pm

In the final minutes of Apollo 11’s descent to the lunar surface, five 1201 and 1202 alarms blared in the lunar module. The computer was overloaded with data, and for a brief moment it looked like Neil Armstrong and Buzz Aldrin wouldn’t land on the Moon. As we know, they did; Apollo 11 got a GO to land in spite of the alarms. What we don’t know is the man whose work allowed the crew reboot the computer and save the landing: Hal Laning.

Apollo 10, the Mission That Got So Close to Landing on the Moon

By Amy Shira Teitel | May 11, 2019 11:32 am

AS10 Crew NASAApollo 10 doesn’t get much attention. On the rare occasion people talk about the mission right before the first lunar landing, it’s lumped into the “pre-Apollo 11” category and dismissed as one of the stepping stones on the bridge to the Moon. But it was far more interesting than just a mission that preceded Apollo 11.  Read More

A Dry Cleaner Once Demanded Restitution from NASA

From the Nixon Library.

The amazing thing about national archives is that these libraries contain absolutely everything. Case in point: I recently found a letter in the Nixon Library from the Apollo Dry & Wet Cleaners in Pakistan. The owner was, apparently, a little miffed NASA took his business’ name for the lunar landing program and wanted press materials as restitution. Read More

Why Apollo Had a Flammable Pure Oxygen Environment

Fire, as we know, needs three things: a source of heat, fuel and oxygen. Apollo lunar missions had all three in spades. There was plenty of electricity running through the spacecraft, lots of material that could be fuel and a 100 percent oxygen atmosphere under pressure. So why exactly did NASA design a spacecraft that was an explosion waiting to happen? (This is a question I get *a lot* so I hope this gives a full answer!) Read More

We Shouldn’t be Scared of Nuclear Rockets in Space

A few weeks ago, a spending bill passed by Congress included $100 million earmarked for NASA to develop nuclear thermal rocket engines. In spite of the ever-present backlash to nuclear material, it’s not uncommon when it comes to space exploration. The Curiosity rover is just one of many NASA missions powered by nuclear material, in this case, a multi-mission radioisotope thermoelectric generator (MMRTG) that converts heat from decaying plutonium-238 into electricity. But that’s robotic and doesn’t impact humans, you say? The Apollo lunar landing missions also had nuclear generators on board; the ALSEPs used radioisotope thermoelectric generators to power some of the surface experiments.

Of course, a nuclear power plant for an instrument isn’t the same as a nuclear engine, but the challenges of working with the dangerous material remain. And yet, this won’t be the first time the space agency has tried to harness nuclear power for space travel. A small number of programs tried to develop nuclear power for manned space missions in the 1960s, one of which was called NERVA.

The Women’s Guide to ID Badge Placement (According to the Government in 1947)

Digging into NASA’s Apollo-era history of nuclear propulsion for manned deep space missions, I found another gem in the history of the government not really knowing how to address women’s clothing. This time, we’re talking beauty and badges. Read More

The New Apollo 11 Documentary is Jaw-Droppingly Gorgeous

By Amy Shira Teitel | March 6, 2019 12:07 pm

The new Apollo 11 documentary boasts that it is a “cinematic event fifty years in the making.” Which it is. It’s less a documentary and more a compilation of restored 16mm film and rarely-if-ever heard audio records from the first lunar landing mission, and it’s absolutely incredible. (Heads up: this blog contains spoilers, but then again, most of us know what happened on Apollo 11, right? Right.) 

The trailer, just in case you haven’t seen it kicking around yet.

NASA’s Bold Apollo 9 Plans Made the Moon Landing Possible

Apollo 9 launched 50 years ago, on March 3, 1969, and it might be the most important but least celebrated of the early Apollo missions. In fact, it was so important to NASA’s ultimate lunar landing goal that the space agency had a series of contingency missions in place to ensure it could get as much data as possible if something went wrong.

Vintage Space

Vintage Space is all about digging into the minutia of the space age. Rather than retelling glossy stories of astronauts, Vintage Space peels back that veneer to look at the real stories -- the innovations that failed, the unrealized technologies, and the human elements that are less publicity-friendly so often remain buried. Gaining a clear picture of spaceflight's past ultimately helps us understand our present position in space and have a more realistic expectation of what the future might bring.
