“Don’t let the NASA emblem scare you away.

“I was very intimidated by it because it was a childhood dream [to make it to NASA]. I saw a picture of me at Kennedy Space [Center’s] visitor center the last time I went home. I must have been five years old. I always used to tell myself that I wasn’t smart enough. [I assumed you needed to be] a literal rocket scientist, and I have absolutely no STEM [science, technology, engineering, and math] degree whatsoever.

“So my advice is, as long as you’re true to who you are, you’re transparent, you’re yourself, and you put the work in, you will get what you want.

“And make them tell you no — that was one of the first things I learned. If you don’t ask and you don’t apply, you have your answer. So make them tell you no. If you don’t ask, you’ll never know.

“And don’t be intimidated or influenced by an emblem or your perception of what kind of people are behind that emblem. Because now I realize, once I’ve made it to NASA, that it’s nothing like I thought it was. In a lot of ways, it’s better, right? Because I get these opportunities to do things that are not in my primary role to serve others, and in that capacity, it’s serving me. That’s my advice.”

Johnson Celebrates LGBTQI+ Pride Month: Meet Margaret Kennedy

Johnson Celebrates LGBTQI+ Pride Month: Meet Margaret Kennedy

Although surrounded by the big and bold missions of human spaceflight, Margaret Kennedy, an aerospace systems engineer on the Human Health and Performance Contract, still appreciates the little things. Ask about her favorite NASA experience to date and she will tell you it is getting to show her badge to the gate guards at Houston’s Johnson Space Center every day. “Knowing I get to be a part of things that can change the world – that I’m helping to make it possible for astronauts to do their job safely, which in turn supports life on Earth – is very rewarding,” she said.

Kennedy joined the Johnson team as a contractor with Aegis Aerospace in October 2019. Since then, she has spent most of her time as a systems engineer for the Human Research Program’s Program Integration and Strategic Planning group. That role required her to collect technical information for various projects and to ensure systems were in place to correctly track and manage program documents and agreements. This spring, Kennedy transitioned to a new role in which she provides systems engineering for flight hardware supporting Gateway and exploration missions to the Moon and Mars.

She started engaging with Johnson’s Employee Resource Groups (ERGs) shortly before the COVID-19 pandemic and jumped at the chance to get more involved once employees came back onsite. “A few people have been surprised when I tell them I’m really an introvert, not an extrovert, but I had to get out of my shell or I’d still be stuck in my apartment,” she said. “The ERGs were a way for me get out of my space and have allowed me to grow.”

Kennedy is thankful the Johnson Parenting ERG started allowing contractors to serve as secretaries because that led to similar opportunities with other ERGs. She served as the membership secretary for both Emerge and Out & Allied ERG (OAERG) in 2023 and is currently OAERG’s executive secretary. “I help keep our chair and co-chair up to date,” she said. “I have my finger on everything that’s happening in the ERG.” Filling these roles gives Kennedy numerous opportunities to support diversity, equity, and inclusion at Johnson, the most recent of which was her participation on a panel during the center’s Diversity, Equity, Inclusion, and Accessibility Day.

“The main advice I’d give to others wanting to get involved is find your people and don’t be afraid to take a risk,” she said. “Many of us deal with risk every day in our work so find a way to buy down risk by finding allies and a support system. Even if you only get a hair’s width outside your zone of comfort, it makes a difference.”

She also said that simply participating in ERG meetings and events – whether in person or virtually – is another great way to get involved. “The ERGs can’t do what we do without you,” she said. “We do it because it’s important to us and to others, but we sometimes struggle to know what people want. We need your thoughts and your ideas because it helps us provide programming and inform the center about what is happening.”

Being a part of OAERG in particular has helped Kennedy personally and professionally. “It has provided me with a space to be my authentic self and bring that person to both the world and work,” she said. “In the long line of LGBTQI+ letter soup, I end up in the + on the end more times than not. Out & Allied has given me a way to not only embrace my identity but also help spread awareness about it.” Professionally, the ERG has helped her network with a range of people, including upper and middle management, and strengthen her communication, problem solving, and leadership skills.

Kennedy acknowledged that change can take time, noting that while Johnson’s safety-oriented culture is a strength, it can sometimes slow the pace of initiatives that may not be considered mission critical, as can staffing shortages in some areas. “Things like accessible walkways and gender-neutral bathrooms are still important,” she said, adding that leadership is working on it.

Kennedy encourages everyone at Johnson to check in with their teammates and have “water cooler moments” with their colleagues as a way of promoting inclusivity. “Be patient and willing to give everyone some grace,” she said. “We can get so focused on the mission and what we need that we sometimes forget there are things happening in other people’s lives that can affect their work.”

Hubble Observes a Cosmic Fossil

A globular cluster that looks like a very dense, ball-shaped collection of many shining stars in colors of white, yellow-orange, and blue. Some stars appear a bit larger and brighter than others, with the brightest having faint cross-shaped diffraction spikes. The cluster’s stars are scattered mostly uniformly, with their density increasing toward the cluster’s core where they merge into a strong, bright-white glow.

This NASA/ESA Hubble Space Telescope image features the globular cluster NGC 2005. It’s not an unusual globular cluster in and of itself, but it is a peculiarity when compared to its surroundings. NGC 2005 is located about 750 light-years from the heart of the Large Magellanic Cloud (LMC), which is the Milky Way’s largest satellite galaxy some 162,000 light-years from Earth. Globular clusters are densely-packed groups of stars that can hold tens of thousands or millions of stars. Their density means they are tightly bound by gravity and therefore very stable. This stability contributes to their longevity: globular clusters can be billions of years old, and are often comprised of very old stars. Studying globular clusters in space can be a little like studying fossils on Earth: where fossils give insights into the characteristics of ancient plants and animals, globular clusters illuminate the characteristics of ancient stars.

Current theories of galaxy evolution predict that galaxies merge with one another. Astronomers think the relatively large galaxies we observe in the modern universe formed when smaller galaxies merged. If this is correct, then we would expect to see evidence that the most ancient stars in nearby galaxies originated in different galactic environments. Because globular clusters hold ancient stars, and because of their stability, they are an excellent laboratory to test this hypothesis.

NGC 2005 is such a globular cluster, and its very existence provides evidence that supports the theory of galaxy evolution via mergers. Indeed, what makes NGC 2005 a bit peculiar from its surroundings, is the fact that its stars have a chemical composition that is distinct from the stars around it in the LMC. This suggests that the LMC underwent a merger with another galaxy somewhere in its history. That other galaxy has long-since merged and otherwise dispersed, but NGC 2005 remains behind as an ancient witness to the long-past merger.

The U.S. spacewalk 90 planned Thursday at the International Space Station did not proceed as scheduled due to a spacesuit discomfort issue.

NASA astronauts Tracy C. Dyson and Matthew Dominick completed taking off their spacesuits about an hour before the crew was anticipated to exit the Quest airlock.

With consideration to NASA’s Boeing Crew Flight Test and other spaceflight operations, the next spacewalk will be Monday, June 24, followed by another on Tuesday, July 2, as was previously planned. The June 24 spacewalk will focus on radio frequency group hardware removal, while the content of the July 2 spacewalk is under evaluation and will be shared as available. The crew members on the station are healthy, and spacesuits are functioning as expected.

Sols 4214–4215: The Best Laid Plans…

Earth planning date: Wednesday, June 12, 2024

Planning today was defined by the decision about whether or not to drill at “Mammoth Lakes,” the potential drill target that we selected on Monday. This decision is made based on the answer to two questions. First, does this location meet our science objectives? On Monday, we undertook some exploratory contact science (primarily with APXS) to answer this question by determining the likely elemental composition of Mammoth Lakes. Second, is it safe to drill here? Monday’s plan also included a “preload test” to determine the safety of drilling by using the arm to place some pressure on Mammoth Lakes. We do these activities to measure the forces we expect on the arm while drilling and to see if the rock is stable enough to drill into. Although the APXS data indicated that this location meets our science objectives, the preload test was unsuccessful. Consequently, we had to pull the drill activities from the plan. 

The drill activities had been scheduled to consume the entire first sol of this two sol plan. Unfortunately, the assessment of the preload data came too late to properly pivot from a drilling sol, so we were unable to plan any observations to replace the pulled drill activities. This means that Curiosity gets to take an unplanned vacation with just REMS and RAD observations on the first sol.

The second sol looks more like a typical plan, though we had to pull a number of drill-related activities here as well, so it’s a bit emptier than usual. We begin with a Mastcam tau observation looking at the amount of dust in the atmosphere, then move on to a set of Mastcam and Navcam photometry images. These photometry observations take several images of the ground near the rover at different times of day to help us understand how sunlight scatters off of the rocks around us. We take a quick break from science to let the rover communicate with Earth through the Mars Relay Network, then get right back to work with ChemCam. LIBS will be used on the target “Golden Trout Lake,” then we’ll get an RMI mosaic of an area about 15 metres away from the rover.

Once ChemCam is done, we’ll have our second set of Mastcam and Navcam photometry observations to complement those taken earlier in the sol. We’ll then take Mastcam images of the Golden Trout Lake LIBS target, one of ChemCam’s AEGIS targets, and some light-toned rocks at “Camp Four.” Mastcam will also be monitoring “Walker Lake,” a nearby patch of sand, to see how the wind is moving the sand around.

Today’s plan wraps up with a collection of environmental science activities, including a dust devil survey, suprahorizon movie, and a line-of-sight mosaic of the north crater rim, as well as our usual suite of REMS, DAN, and RAD observations.

Despite the challenges of today, we’re not giving up just yet. This isn’t our first failed preload test, so the team is now looking for somewhere else in this area to drill. Hopefully we won’t have the same difficulties as when we were trying to drill at the Marker Band, but nobody ever said that drilling a hole in a rock from over 270 million kilometres away was easy!
