From the iconic image of Earthrise taken by Apollo 8 crew, to the famous Pale Blue Dot image of Earth snapped by Voyager I spacecraft, to state-of-the-art observations of our planet by new satellites such as PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), NASA has given us novel ways to see our home. This Earth Day, NASA is sharing how — by building on decades of innovation—we use the unique vantage point of space to observe and understand our dynamic planet in ways that we cannot from the ground.

NASA has been observing Earth from space for more than 60 years, with cutting-edge scientific technology that can revolutionize our understanding of our home planet and provide benefits to all humanity. NASA observations include land data that helps farmers improve crop production, research on the air we breathe, and studies of atmospheric layers high above us that protect every living thing on the planet.

“NASA Science delivers every second of every day for the benefit all, and it begins with how we observe our home planet from the unique vantage point of space,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Our satellites, Mars rovers, astronauts and other NASA Science missions send back beautiful images of our planet, from the smallest of plankton to the pale blue dot, to help give us a comprehensive, detailed view of our home that we especially celebrate each Earth Day.”

NASA data and tools are vital to federal, state, local, and international governments to monitor and manage land, air, and water resources. From mapping the ocean floor to finding critical mineral deposits to alerting land managers when fire risk is high, NASA’s data and information informs nearly every aspect of our economy and our lives.

“Another way NASA celebrates Earth Day is by sharing information about how our science benefits the entire nation, such as by providing U.S. farmers and ranchers with ongoing measurements of water, crop health, wildfire predictions, and knowledge of what is being grown around the world,” said Karen St. Germain, director of NASA’s Earth Science Division at the agency’s headquarters in Washington. “This data informs field level farming and ranching decisions with impact felt as far as the commodity-trading floor and our grocery stores.”

Next up for NASA’s work to help mitigate natural disasters is a mission called NISAR (NASA-ISRO Synthetic Aperture Radar) which is a partnership between NASA and ISRO (India Space Research Organization). NISAR, which is targeted to launch later this year, will measure land changes from earthquakes, landslides, and volcanos, producing more NASA science data to aid in disaster response. The mission’s radar will detect movements of the planet’s surface as small as 0.4 inches over areas about the size of half a tennis court. By tracking subtle changes in Earth’s surface, it will spot warning signs of imminent volcanic eruptions, help to monitor groundwater supplies, track the melt rate of ice sheets tied to sea level rise, and observe shifts in the distribution of vegetation around the world. 

From our oceans to our skies, to our ice caps, to our mountains, and to our rivers and streams, NASA’s Earth observations enhance our understanding of the world around us and celebrate the incredible planet we call home.

Earth planning date: Friday, April 18, 2025

As the APXS operations person today, I was hopeful that we could plan a compositional measurement after brushing one of the bedrock blocks in front of the rover. However, it soon became clear that the rover was not on stable enough ground to safely unstow the arm and place APXS and MAHLI. Silver linings though; by not having any arm movement in this plan, which requires significant energy, we were able to conserve power for what we hope will be a busy week of upcoming science activities as we drive towards our next high priority area of interest – the so-called boxwork formations. These are large resistant ridges identified from orbit, which may be the result of fracturing, fluid flow and alteration within the sulfate unit that we are traversing through. We plan to image them on approach to gain insights into their context.

Despite the loss of arm activities, we still have plenty of interesting observations planned for this 3-sol weekend. ChemCam will fire its laser at two separate rock targets, “Santa Ynez” and “Cahuilla”, which will also be captured with Mastcam documentation images. The targets are on two different bedrock blocks with the “Cahuilla” raster focused on a thin resistant layer. ChemCam will also use its remote imaging capabilities to obtain mosaics of the “Texoli” butte and another interesting feature, “Torote Bowl”. Mastcam will capture mosaics of “San Gabriel River” (an apparent angular contact) and of some sand troughs surrounding many of the bedrock blocks in this region. An image will also be acquired of a small, grey float pebble, “Piru Creek.”

The environmental science group was also able to plan a number of activities to catch up on their regular cadence, which has been impacted by the recent power constraints. We are acquiring Navcam line of sight observations (x2), suprahorizon movies (x2), a zenith movie and a 360 degree sky survey, as well as a Mastcam sky survey. Coordinated ChemCam passive sky and APXS atmospheric observations are also planned.

There is a ~19 m drive planned through this tricky terrain that will hopefully set us up for arm activities (APXS and MAHLI) in our new workspace next week. The plan is completed with standard RAD, DAN and REMS activities, as well as two MARDI images to record the terrain beneath the rover in the current and new workspace.

Following the successful launch of NASA’s SpaceX 32nd Commercial Resupply Services mission, new scientific experiments and supplies are bound for the International Space Station.

The SpaceX Dragon spacecraft, carrying approximately 6,700 pounds of cargo to the orbiting laboratory for NASA, lifted off at 4:15 a.m. EDT Monday, on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Live coverage of the spacecraft’s arrival will begin at 6:45 a.m., Tuesday, April 22, on NASA+. Learn how to watch NASA content through a variety of platforms.

The spacecraft is scheduled to autonomously dock at approximately 8:20 a.m. to the zenith, or space-facing, port of the space station’s Harmony module.

The resupply mission will support dozens of research experiments during Expedition 73. Along with food and essential equipment for the crew, Dragon is delivering a variety of science experiments, including a demonstration of refined maneuvers for free-floating robots. Dragon also carries an enhanced air quality monitoring system that could help protect crew members on exploration missions to the Moon and Mars, and two atomic clocks to examine fundamental physics concepts, such as relativity, and test global synchronization of precision timepieces.

These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory each year in the areas of biology and biotechnology, physical sciences, and Earth and space science. Such research benefits humanity and helps lay the groundwork for future human exploration through the agency’s Artemis campaign, which will send astronauts to the Moon to prepare for future missions to Mars.

The Dragon spacecraft is scheduled to remain at the orbiting laboratory until May, when it will depart and return to Earth with time-sensitive research and cargo, splashing down off the coast of California.

NASA astronaut Don Pettit returned to Earth Saturday, accompanied by Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, concluding a seven-month science mission aboard the International Space Station.

The trio departed the space station at 5:57 p.m. EDT aboard the Soyuz MS-26 spacecraft before making a safe, parachute-assisted landing at 9:20 p.m. (6:20 a.m. on Sunday, April 20, Kazakhstan time), southeast of Dzhezkazgan, Kazakhstan. Pettit also celebrates his 70th birthday on Sunday, April 20.

Spanning 220 days in space, Pettit and his crewmates orbited the Earth 3,520 times, completing a journey of 93.3 million miles. Pettit, Ovchinin, and Vagner launched and docked to the orbiting laboratory on Sept. 11, 2024.

During his time aboard the space station, Pettit conducted research to enhance in-orbit metal 3D printing capabilities, advance water sanitization technologies, explore plant growth under varying water conditions, and investigate fire behavior in microgravity, all contributing to future space missions. He also used his surroundings aboard station to conduct unique experiments in his spare time and captivate the public with his photography.

This was Pettit’s fourth spaceflight, where he served as a flight engineer for Expeditions 71 and 72. He has logged 590 days in orbit throughout his career. Ovchinin completed his fourth flight, totaling 595 days, and Vagner has earned an overall total of 416 days in space during two spaceflights.

NASA is following its routine postlanding medical checks, the crew will return to the recovery staging area in Karaganda, Kazakhstan. Pettit will then board a NASA plane bound for the agency’s Johnson Space Center in Houston. According to NASA officials at the landing site, Pettit is doing well and in the range of what is expected for him following return to Earth.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a strong low Earth orbit economy, NASA is focusing more resources on deep space missions to the Moon as part of Artemis in preparation for future astronaut missions to Mars.

Hubble Spies Cosmic Pillar in Eagle Nebula

A tall, thin structure of dark gas clouds. This pillar is darker and broader at its base, thins toward the middle, and broadens out again at the top, with spikes, fingers, and wisps of gas protruding in all directions from its head. Some parts of the pillar are illuminated, but most are dark and silhouetted at the edges and lit from behind. A wall of colorful gas lies behind the pillar, bluish at the top and redder toward the bottom, with several blue and gold stars scattered across it.

As part of ESA/Hubble’s 35th anniversary celebrations, the European Space Agency (ESA) is sharing a new image series revisiting stunning, previously released Hubble targets with the addition of the latest Hubble data and new processing techniques.

New images of NGC 346 and the Sombrero Galaxy have already been published. Now, ESA/Hubble is revisiting the Eagle Nebula (originally published in 2005 as part of Hubble’s 15th anniversary celebrations) with new image processing techniques.

Unfurling along the length of the image is a pillar of cold gas and dust that is 9.5 light-years tall. As enormous as this dusty pillar is, it’s just one small piece of the greater Eagle Nebula, also called Messier 16. The name Messier 16 comes from the French astronomer Charles Messier, a comet hunter who compiled a catalog of deep-sky objects that could be mistaken for comets.

This pillar is darker and broader at its base, thins toward the middle, and broadens out again at the top, with spikes, fingers, and wisps of gas protruding in all directions from its head.

The name Eagle Nebula was inspired by the nebula’s appearance. The edge of this shining nebula is shaped by dark clouds like this one, giving it the appearance of an eagle spreading its wings.
Not too far from the region pictured here are the famous Pillars of Creation, which Hubble photographed multiple times, with images released in 1995 and 2015.

The heart of the nebula, which is located beyond the edge of this image, is home to a cluster of young stars. These stars have excavated an immense cavity in the center of the nebula, shaping otherworldly pillars and globules of dusty gas. This particular feature extends like a pointing finger toward the center of the nebula and the rich young star cluster embedded there.

The Eagle Nebula is one of many nebulae in the Milky Way that are known for their sculpted, dusty clouds. Nebulae take on these fantastic shapes when exposed to powerful radiation and winds from infant stars. Regions with denser gas are more able to withstand the onslaught of radiation and stellar winds from young stars, and these dense areas remain as dusty sculptures like the starry pillar shown here.

This towering structure of billowing gas and dark, obscuring dust might only be a small portion of the Eagle Nebula, but it is no less majestic in appearance for it. 9.5 light-years tall and 7000 light-years distant from Earth, this dusty sculpture is refreshed with the use of new processing techniques.
