A Master Class in Space Photography with NASA Astronaut Donald Pettit

(...) MT: TIME actually just got to do a video-chat with Reid Wiseman, Steve Swanson and Alexander Gerst on the ISS last week. Have they come to you and asked for any advice on how to photograph from the Space Station?

DP: I’ve been corresponding with them via email to help them set up some photo situations. One of my ground jobs right now is to write a technical report on photography in space. My working title is Astronauts’ Guide to Photography in Space. It’s written for astronauts, so it basically assumes that if I’m talking about going into the PMA and doing something that you know what the PMA is. It’ll probably be 50 pages. It doesn’t say anything about how to use the cameras, it assumes that you know how to use our Nikon D3S’s and D4’s. It just tells you how you should be setting the camera up for different situations.

Astronaut Don Pettit, a veteran of more than a year in orbit, the fourth most experienced U.S. spacefarer of all time, and the oldest American ever to participate in a long-duration mission to the International Space Station (ISS), turns 60 today (Monday, 20 April). A chemical engineer by training and a former scientist at Los Alamos National Laboratory in Los Alamos, N.M., Pettit unsuccessfully applied three times to enter NASA’s astronaut corps, before finally being accepted as a Mission Specialist candidate in April 1996. Since then, he has flown two lengthy expeditions to the ISS—the first of which came about by serendipity, following the grounding of a member of the prime crew—and a 16-day shuttle mission, which has left him with almost 370 days of cumulative time in space and over 13 hours of spacewalking expertise in two EVAs.

This is why there are no spectacular photos from @Space_Station of the recent worldwide display of auroras.
For a few days about twice a year the orbit of ISS aligns with the day-night terminator, continuously straddling the border between light and dark. With no night, photography of auroras is difficult.

I'm not sure what made this streak. It looks like a burning meteor but appears significantly above the atmosphere from this perspective.
It might be a solar reflection "flash" from an Iridium satellite. Any ideas?

The streak in the image is likely due to a reflection from an Iridium satellite or another similar satellite, as their reflective surfaces can create bright streaks visible from space. Alternatively, it could be a high-altitude meteor captured by the sensitive camera settings. 🔭

This was so fascinating.  I had a teflon knitting needle on @ISS and charged it by rubbing with my Russian fur boots.  Then I directed water droplets from a syringe towards the charged knitting needle and this is the resulting dynamics.  The droplets, due to charge forces, go into a crazy orbit around the knitting needle.  If planets were cylindrical this would be the orbit of its moons due to gravity.  Canon G1 video camera, Expedition 30, 2012.

Astronauta ma nowy obiekt do obserwacji.
Kometa C2023-A3 (Tsuchinshan-ATLAS).

It is totally awesome to see a comet from orbit. The perspective of rising through the atmosphere on edge is truly unique from our vantage point. The comet tail is still too dim to see with your eyes, but it is heading towards the sun and growing brighter every day.

This comet is known as C2023-A3 or Tsuchinshan-ATLAS. @dominickmatthew used math (go figure) and our orbital geometry to figure out where to point our cameras and was the first to get a good photo (https://x.com/dominickmatthew/status/1836916069870751825?s=46).

Using Matthew’s technique, I will photograph every day to see what develops in the tail structure. Currently, there appears to be a forward directed “tail” that I am not certain is real or an artifact from shooting through 4 window panes. Time will tell if this structure brightens. Stay tuned.

An amateur astronomer told @astro_Pettit that the comet would be about 20 degrees ahead of the sun from our perspective. We needed photos to be taken when we were on the dark side of the Earth because the comet is still very dim. We have software on the ISS that tells us when orbital sunrise will occur. So we did a simple estimate to figure out when and where to point the cameras. (20 deg / 360 deg)*90 min/orbit for the ISS = 5 min. This told us we should expect the comet to rise out of the horizon 5 minutes prior to orbital sunrise. With the naked eye the comet is still just a dot and pretty much indiscernible from stars . . . so about 7 minutes prior to sunrise we started scanning the horizon back and forth with a 200mm lens looking through he viewfinder for the comet.  You can imagine how we felt when it appeared. Math works!

The way we sprinkle our light bulbs out says something about our cities. Some cities are laid out in north-south grids, as if an engineer designed them with a master plan, and others show a spider-web network of haphazard lighting. Perhaps what was a meandering cow trail/wagon road is now a well-lit superhighway.

Let’s look at a few examples:

First, old town Denver has meandering streets, where new Denver shows the typical north-south, east-west grids from a master-planned cityscape. Boulder is dimly seen to the northwest, a fine example of engineered street lighting to minimize light pollution.

Moonshine from space. Somewhere over the Amazon basin, shooting photos of cities at night, I noticed the light from a near-full moon reflecting off of the meandering rainforest rivers. In the cool moon-ish light these rivers became flowing silver snakes. When the moonlight was filtered through thunderheads, it turned the rivers into glowing golden claws.

The anti-smoking point is out of context, but I believe one of America’s greatest public policy decisions was the complete 180 on smoking.
People should have the right, but because that right endangers oneself and others, it must be limited.

Formation flight; comet C/2023-A3 (Tsuchinshan-ATLAS) and a meteor burning up in the atmosphere. This looks like they are traveling in formation but are unrelated and only by chance did this get caught by camera.

This was taken on UT day 267 (Monday Sept. 23), and since then the comet has gotten much brighter. I look forward to it in a few weeks where it should become spectacular, both from space and from Earth.

On @Space_Station, we go by GMT or UT time and dates, so it is easy to lose track of what day of the week it is. For us on station, UT dates just become a number. Only when I try to interact with earthlings do the seven-day week labels become important.

4) Amsterdam
11:25 PM · Oct 1, 2024

City at Night: Amsterdam edition. Space travelers from all over the world (more than 100 astronauts from 38 countries) are there right now for the Association of Space Explorers Planetary Congress. Technical exchange is flowing freely as they continue to build and strengthen the international cooperation that makes it possible for humans to explore the stars.
Nikon Z9, 200mm, f2, 1/320th second, ISO 25600.

[Orionid]

Kair z piramidami bardzo oświetlony i Luksor (Teby) ze świątynią Karnak w ciemnościach.

Cities at night: Cairo with pyramids and Luxor (Thebes) with the Karnak Temple. Can you find them?  While Luxor is well lit, the City of the Dead is respectfully dark. There is some ancient human feeling, a residual in our being, that draws one to the Nile River, on Earth and especially so from orbit. I once sailed down the Nile River in an open felucca from Aswan to Luxor and now fly above from space. What a strange juxtaposition of views.

2) Połączenie Sycylii z „Butem” w fałszywych kolorach bliskiej podczerwieni.

8:31 PM · Oct 4, 2024
The junction between Sicily and the “Boot” in near infrared false colors. Mount Etna is quiet today. Here the wavelength of light is restricted from 550nm (green) to 1200nm (near infrared), capturing light and detail that we cannot see with our eyes nor with normal photography. The color spectrum assigned here renders highly reflective infrared subjects as red and magenta. This yields lush vegetation as red-magenta and brings out details in the ocean currents that are difficult to otherwise see.

Nikon Z9 with IR blocking filter removed, sensitive from 550 to 1200 nm, Nikon 70-200mm zoom set 70mm, f8, 1/6400 sec, ISO 500, adjusted in Photoshop (noise reduction, red-blue color swap, contrast).

Los Alamos, Valle Grande Caldera, region Jemez w Nowym Meksyku.
Odpowiednie jest uchwycenie tego obrazu w fałszywych kolorach bliskiej podczerwieni.
Roślinność i klify tufu wulkanicznego pojawiają się jako magenta.

Los Alamos, Valle Grande Caldera, Jemez region of New Mexico. I spent my early career at Los Alamos National Laboratory, where I grew up from a freshly minted graduate student into a professional staff researcher. My scientific colleagues helped warp me into the scientist I am today. It is appropriate to capture this image in false color near infrared. Vegetation and the volcanic tuff cliffs appear as magenta.

Nikon Z9 with IR blocking filter removed, sensitive from 550 to 1200 nm, Nikon 70-200mm zoom set 130mm, f8, 1/5000 sec, ISO 500, adjusted in Photoshop (noise reduction, red-blue color swap, contrast).
