When an asteroid or comet comes close to Earth we call it a near-Earth object. But how close is close? How do we keep track of them? What can we do to mitigate our risk? We have the answers.⁣⁣⁣
⁣⁣⁣
Here’s what you need to know about near-Earth objects this #AsteroidDay! ⁣⁣⁣

Can you see the shadows of "wings" near the top of this @NASAHubble image? πŸ¦‡⁣

Our Hubble Space Telescope saw a fledgling star’s unseen, planet-forming disk casting a huge shadow across a more distant cloud in a star-forming region. Astronomers nicknamed this feature the “Bat Shadow,” because it resembles a pair of wings. The shadow moves as the disk - a circling structure of gas, dust, and rock - rotates around the young star, known as HBC 672.⁣

πŸ‘©πŸΎ‍πŸ”¬πŸš€πŸŒŸ Mary Jackson never accepted the status quo.⁣⁣⁣
⁣⁣⁣
Today we announced that our headquarters building in Washington, DC, will be named after engineer Mary W. Jackson, who overcame barriers to become NASA’s first Black woman engineer. ⁣⁣⁣
⁣⁣⁣
Jackson started her NASA career in 1951 at what is now @NASALangley in Virginia as a human computer – a mathematician who performed hand calculations for NASA missions. After two years working in the West Area Computing unit, she received an offer to work in Langley’s Supersonic Pressure Tunnel, where she conducted extensive aeronautics research and authored or co-authored over a dozen research papers. She was promoted and, in 1958, became our first Black woman engineer.⁣⁣⁣
⁣⁣⁣
In 1979, Jackson made a final career change, leaving engineering to become the program manager for NASA Langley’s Federal Women’s Program. She would dedicate the rest of her career to the hiring and promotion of the next generation of women mathematicians, scientists, and engineers. She was posthumously awarded the Congressional Gold Medal in 2019 and was portrayed by @JanelleMonae in the Oscar-winning film #HiddenFigures.⁣⁣⁣
⁣⁣⁣
Our Administrator @JimBridenstine noted, "We know there are many other people of color and diverse backgrounds who have contributed to our success, which is why we’re continuing the conversations started about a year ago with the agency’s Unity Campaign. NASA is dedicated to advancing diversity, and we will continue to take steps to do so.”⁣⁣⁣

When our Perseverance Mars rover lands on the Red Planet, it will be caching rock samples for a future mission to collect and return to Earth. For Mars 2020 Deputy Project Scientist at @NASAJPL Katie Stack Morgan, studying rocks is not only important in the search for ancient life, but it’s also a hobby.⁣

Perseverance is on track to launch on July 20 and land in Mars’ Jezero Crater in February 2021. ⁣

An astronaut's view of sunglint reflecting off the Mediterranean Sea β˜€οΈ⁣⁣
⁣⁣
The islands of Corsica and Sardinia are highlighted in this photo taken from the International Space Station (@iss). The islands have rugged, mountainous terrain with small lakes that also reflect sunlight.⁣⁣
⁣⁣
Clouds are scattered throughout the photo, with some of those over the water aligning with changes in sunglint patterns. The intensity of sunglint depends on the Sun’s angle with respect to the space station's orbit path and the astronaut’s point of view. But it also depends upon the smoothness or roughness of the water surface.⁣⁣
⁣⁣
South of Sardinia, the coasts of Tunisia and Algeria also have the dark, vegetated hue indicative of the Mediterranean climate. Looking farther toward the horizon, the Sahara Desert stretches as far as the eye can see. ⁣⁣

πŸ¦‹πŸžβ € @NASAHubble’s full range of imaging capabilities are revealed here in these images of two young planetary nebulas. NGC 6303 is dubbed the Butterfly Nebula because of its wing-like appearance. In addition, NGC 7027 resembles a jewel bug, an insect with a brilliantly colorful metallic shell. The researchers have found unprecedented levels of complexity and rapid changes in jets and gas bubbles blasting off of the stars at the centers of both nebulas. Hubble is allowing the researchers to converge on an understanding of the mechanisms underlying the chaos. Image Credits: NASA, ESA and J. Kastner (RIT)β €

It takes thousands of people and years of hard work to get a spacecraft from Earth to Mars. So when our Perseverance rover touches down on the Martian surface, it will be because of the talented minds that helped to make it happen.

The team is on track to launch Perseverance on July 20 and land in Mars’ Jezero Crater in February 2021. Each week leading up to launch, learn not only what it’s like to work on this mission but also about the diverse background and career trajectories of team members at @NASAJPL. #CountdownToMars

Mark your calendars – @NASAAstronauts will be venturing into the vacuum of space soon. ⁣

On June 26 and July 1, watch International Space Station (@ISS) Commander Chris Cassidy (@Astro_Seal) and Joint Operations Commander Bob Behnken exit the orbital lab to continue upgrades on its power systems. ⁣

Cassidy has logged 31 hours, 14 minutes of time outside the space station and is pictured here on his last spacewalk in 2013. Behnken, who recently arrived to space with @Astro.Doug as a part of our May 30 #LaunchAmerica mission, has previously logged more than 37 hours during six spacewalks. ⁣

Each year, Saturn's moon Titan drifts a little farther away from its planet. ⁣

How far does it drift? About 4 inches (11 cm) per year. As a moon orbits, its gravity pulls on the planet, causing a temporary bulge in the planet as it passes.⁣ Over time, the energy created transfers from the planet to the moon, nudging it farther and farther out.

The discovery was made using data from our @NASASolarSystem Cassini mission to Saturn, which ended in 2017. While scientists know that Saturn formed 4.6 billion years ago in the early days of the solar system, there's more uncertainty about when the planet's rings and its system of more than 80 moons formed. ⁣

The revised rate of its drift suggests that the moon started out much closer to Saturn, which would mean the whole system expanded more quickly than previously believed. Click the link in bio for more. ⁣

With two @nasaastronauts aboard, the @spacex Dragon Endeavour spacecraft approaches the International Space Station on May 31. Part of southwestern Turkey — including the coastal city of Demre — can be seen in the background. ⁣

The Dragon lifted off on Sat., May 30, aboard a Falcon 9 rocket from our Kennedy Space Center in Florida, the first launch of astronauts from American soil since the end of the Space Shuttle Program in 2011. During the journey to the station, astronauts Bob Behnken and Doug Hurley (@astro.doug) revealed that they had named their spacecraft Endeavour as a tribute to the first space shuttle that both astronauts had flown aboard.⁣

Dragon Endeavour docked successfully about 19 hours after reaching orbit. It arrived at the space station’s Harmony port while both were about 262 miles (422 km) above the northern border of China and Mongolia. ⁣

Space is hard. You've probably heard this before.⁣⁣⁣
⁣⁣⁣
And it rings true today. Earlier this afternoon, weather scrubbed our @SpaceX launch to the @iss. @astro.doug and astronaut #BobBehnken were strapped into their Crew Dragon spacecraft when ground teams called off the 4:33pm ET launch due to inclement weather brought on by Tropical Storm Bertha off the southeastern U.S. coast. The Falcon 9 rocket is healthy, but we want to get it right. Safety is paramount.⁣⁣⁣
⁣⁣⁣
Join us for our next launch attempt on Saturday, May 30, at 3:22pm ET (7:22pm UTC). Our live coverage starts at 11am ET (3pm UTC) on nasa.gov. As part of our Commercial Crew Program, the liftoff will mark the first time in nearly a decade that @nasaastronauts launch on a brand new spacecraft from U.S. soil. We're ready.⁣⁣⁣
⁣⁣⁣
Let's light this candle. πŸš€⁣⁣⁣

πŸŒ… Every sunset brings the promise of a new dawn.⁣⁣
⁣⁣
A new era of space exploration begins on May 27. Nine years after the final space shuttle mission, we’re once again launching astronauts from U.S. soil. On board the Crew Dragon spacecraft that sits atop the @SpaceX Falcon 9 rocket are veteran astronauts @astro.behnken and @astro.doug. But the crew alone won’t fill the crew cabin. Flying with them are the dreams of everybody who ever dared to explore. They are the dreams of the generations that saw 12 humans walk on the Moon. They are the dreams of young boys and girls who will watch a woman take that first step on the Moon in 2024 under our Artemis program. ⁣⁣
⁣⁣
May 27 will be noted as yet another day in history when people can say, “I remember what I was doing that day.” How will you watch history tomorrow? Show us by tagging @nasa in your posts and using the hashtag #LaunchAmerica. You might just make it onto our broadcast.⁣⁣ Live NASA TV coverage starts at 12:15pm ET (4:15pm UTC) at nasa.gov/live.
⁣⁣
Remember: the future is bright because you're in it. ✨⁣⁣
