NASA Space shuttle Atlantis lifts off in this Nov. 3, 1994, image, with NASA astronauts Donald R. McMonagle, Curtis L. Brown, Jr., Ellen S. Ochoa, Scott E. Parazynski, and Joseph R. Tanner, and ESA (European Space Agency) astronaut Jean-Francois-Clervoy aboard. During the 11-day mission, the crew studied Earth’s atmosphere, gathering data on the Sun’s energy output, the atmosphere’s chemical composition, and how these affect global ozone levels.

Sols 4331-4333: Today’s Rover ABC – Aurora, Backwards Driving, and Chemistry, with a Side of Images
This image shows just how variable and interesting the terrain is in the area that NASA’s Mars rover Curiosity is currently investigating. Curiosity captured this long-distance Remote Micro Imager (RMI) image using the Chemistry & Camera (ChemCam) aboard the rover on sol 4329 — Martian day 4,329 of the Mars Science Laboratory mission — on Oct. 10, 2024 at 02:30:12 UTC. NASA/JPL-Caltech/LANL Earth planning date: Friday, Oct. 11, 2024
This blogger is in the United Kingdom, just north of London, where we yesterday had beautiful night skies with a red aurora that was even visible with the unaided eye, and looked stunning on photographs. That reminded me of the solar storm that made it all the way to Mars earlier this year. Here is my colleague Deborah’s blog about it: “Aurora Watch on Mars.” And, of course, that was a great opportunity to do atmospheric science and prepare for future crewed missions, to assess radiation that future astronauts might encounter. You can read about it in the article, “NASA Watches Mars Light Up During Epic Solar Storm.” But now, back from shiny red night skies north of London, and auroras on Mars six months ago, to today’s planning!
Power — always a negotiation! Today, I was the Science Operations Working Group chair, the one who has to watch for the more technical side of things, such as the question if all the activities will fit into the plan. Today there were many imaging ideas to capture the stunning landscape in detail with Mastcam and very close close-ups with the long-distance imaging capability of ChemCam (RMI). Overall, we have two long-distance RMIs in the plan to capture the details of the ridge we are investigating. You can see in the accompanying image an example from last sol of just how many stunning details we can see. I so want to go and pick up that smooth white-ish looking rock to find out if it is just the light that makes it so bright, or if the surface is different from the underside… but that’s just me, a mineralogist by training, used to wandering around a field site! Do you notice the different patterns — textures as we call them in geology — on the rocks to the left of that white-ish rock and the right of it? So much stunning detail, and we are getting two more RMI observations of 10 frames each in today’s plan! In addition there are more than 80 Mastcam frames planned. Lots of images to learn from!
Chemistry is also featuring in the plan. The rover is stable on its wheels, which means we can get the arm out and do an APXS measurement on the target “Midnight Lake,” which MAHLI also images. The LIBS investigations are seconding the APXS investigation on Midnight Lake, and add another target to the plan, “Pyramidal Pinnacle.” On the third sol there is an AEGIS, the LIBS measurement where the rover picks its own target before we here on Earth even see where it is! Power was especially tight today, because the CheMin team does some housekeeping, in particular looking at empty cells in preparation for the next drill. The atmosphere team adds many investigations to look out for dust devils and the dustiness of the atmosphere, and APXS measures the argon content of the atmosphere. This is a measure for the seasonal changes of the atmosphere, as argon is an inert gas that does not react with other components of the atmosphere. It is only controlled by the temperature in various places of the planet — mainly the poles. DAN continues to monitor water in the subsurface, and RAD — prominently featured during the solar storm I was talking about earlier — continues to collect data on the radiation environment.
Let’s close with a fun fact from planning today: During one of the meetings, the rover drivers were asked, “Are you driving backwards again?” … and the answer was yes! The reason: We need to make sure that in this rugged terrain, with its many interesting walls (interesting for the geologists!), the antenna can still see Earth when we want to send the plan. So the drive on sol 4332 is all backwards. I am glad we have hazard cameras on the front and the back of the vehicle!

NASA/Matthew Dominick NASA astronaut Matthew Dominick captured this timelapse photo of Comet C/2023 A3 (Tsuchinshan-ATLAS) International Space Station as it orbited 272 miles above the South Pacific Ocean southeast of New Zealand just before sunrise on Sept. 28, 2024. At the time, the comet was about 44 million miles away from Earth.
Though the comet is very old, it was just discovered in 2023, when it approached the inner solar system on its highly elliptical orbit for the first time in documented human history. Beginning in mid-October 2024, Comet C/2023 A3 (Tsuchinshan-ATLAS) will become visible low in the west following sunset. If the comet’s tail is well-illuminated by sunlight, it could be visible to the unaided eye. Oct. 14-24 is the best time to observe, using binoculars or a small telescope.
The comet hails from the Oort Cloud, which scientists think is a giant spherical shell surrounding our solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt and may contain billions, or even trillions, of objects.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Astronaut Kayla Barron looks at chile peppers growing in the Advanced Plant Habitat aboard the International Space Station. Determining the best ways to water plants in space resulted in the development of a new electrostatic spray nozzle, now licensed to industry.Credit: NASA Whether protecting crops from diseases and pests or sanitizing contaminated surfaces, the ability to spray protective chemicals over important resources is key to several industries. Electrostatic Spraying Systems Inc. (ESS) of Watkinsville, Georgia, manufactures electrostatic sprayers and equipment that make this possible. By licensing NASA electrostatic technology, originally made to water plants in space, ESS’s improved spray nozzles efficiently use basic laws of electricity to achieve complete coverage on targeted surfaces.
ESS traces its origins to research done at the University of Georgia in the 1970s and ’80s. An electrostatic sprayer works by inducing an electric charge onto atomized droplets. Much like an inflated balloon sticking to a wall when it’s gained a charge of static electricity, the droplets then stick to targeted surfaces.
NASA’s interest in this technology originated with astronauts’ need for an easy way to support plant-growth experiments in space. On the International Space Station, watering plants without the help of gravity isn’t as easy as using a garden hose on Earth. In the future, using a system like an electrostatic sprayer on the space station or other orbiting destination could help the water droplets stick to the plants with uniform coverage. However, most spraying systems require large sources of water and air to properly aerosolize fluids.
An ESS mister nozzle undergoes testing at Kennedy Space Center. The design was improved through collaboration between the company and NASA.Credit: NASA As both air and water are precious resources in space, NASA needed an easier way to make these incredibly small droplets. Charles Buhler and Jerry Wang of NASA’s Kennedy Space Center in Florida led the efforts to develop this capability, with Edward Law of the University of Georgia as a consulting expert. Eventually, the NASA team developed a new design by learning from existing technology called a mister nozzle. The benefit of a mister is that even though the interior volume of the nozzle is small, the pressure inside never builds up, which makes it perfect for enclosed small spaces like the space station.
As the sprayer industry is a tight-knit group, technology transfer professionals at NASA reached out to the companies that could use a nozzle like this on Earth. Electrostatic Spraying Systems responded and later licensed the sprayer design from the agency and incorporated it into the company’s Maxcharge product lines.
