Tracking a mission’s historic return to Earth, a year of science onboard the space station, and the safe arrival of the station’s newest resident astronaut … a few of the stories to tell you about – This Week at NASA!

NASA astronaut Randy Bresnik captured this footage with a GoPro camera on Oct. 20, 2017 during a spacewalk outside the International Space Station. Bresnik reflected on this quiet moment, "Sometimes on a #spacewalk, you just have to take a moment to enjoy the beauty of our planet Earth. This Go-Pro footage is from our spacewalk where Joe Acaba and I refurbished the Canadarm2 robotic arm and the Dextre robotic arm extension."

NASA’s Innovative Advanced Concepts (NIAC) Program nurtures visionary ideas from America's innovators and entrepreneurs that could transform future NASA missions with the creation of radically better or entirely new aerospace concepts. NIAC projects study innovative, technically credible, advanced concepts to turn science fiction to science fact.

NASA astronaut Frank Rubio is set to return to Earth this fall after setting the record for the longest single spaceflight by a U.S. astronaut. He arrived at the International Space Station on Sept. 21, 2022, and will return home after 371 days in space. While on the orbiting lab, Rubio and his fellow crew members conducted dozens of scientific investigations and technology demonstrations.

At the Baikonur Cosmodrome in Kazakhstan, the Soyuz 2.1a rocket that will launch the Soyuz MS-24 crew to the International Space Station rolled out from its integration building to the launch pad Sept. 12 for final preparations. While the roll out took place, members of the Expedition 69-70 crew, Soyuz Commander Oleg Kononenko and Flight Engineer Nikolai Chub of Roscosmos and NASA Flight Engineer Loral O’ Hara and their backups, Alexey Ovchinin of Roscosmos and Tracy C. Dyson of NASA participated in final prelaunch training activities.

Lions, the kings of the savannah, are known for their incredible strength and unmatched courage, and possess the attributes of speed, fearlessness, and strong muscles, enabling them to successfully bring down various animals regardless of their size. These solo missions truly showcase the raw power and stealth of these magnificent creatures. From lightning-fast ambushes to calculated strategic moves, male lions prove that they can hold their own in the wild. And let's not forget about their menu! These carnivorous kings have an appetite for some of the toughest prey out there. Zebras, wildebeests, giraffes, elephants, buffaloes—you name it, they'll take it down! Alright, let's get this wild journey started! Hit that like button, subscribe to our channel, and let's dive into the fierce world of male lions hunting alone!

Our SpaceX Crew-6 mission safely returns to Earth, the tech demo hitching a ride on our Psyche spacecraft, and studying ancient life on Earth to better understand Mars … a few of the stories to tell you about – This Week at NASA!

Where are the Moon rocks from the Apollo missions kept? When they’re not being studied by institutions or enjoyed by museumgoers, NASA has a specialized Lunar Sample Curation Laboratory at NASA’s Johnson Space Center to store and keep these otherworldly samples safe. Studying these samples helps us learn more about the origin of not only our moon, but our planet. Deputy Apollo Sample Curator (Sept 2019 – Dec 2022) Dr. Juliane Gross explains more about lunar sample curation.

Our Universe is not silent.. Although space is a vacuum, that does not mean there is no sound in it. Yes, space is a vacuum - so it generally doesn't carry sound waves like air does here on Earth. However, some sounds do exist in outer space, we just can't hear them. Various probes that zoom through the space are capable of capturing radio emissions from astronomical objects. NASA's scientist have designed special instrument known as 'astronomical interferometer' which can record these electromagnetic vibrations, and transfer them into sounds within range of human hearing (20-20,000 Hz). Interesting Facts about our Moon: The Moon's Latin name is Luna. The Moon formed approx. 4.5 billion years ago. Moon is the fifth-largest natural satellite in the Solar System. The moon orbits the Earth at an average speed of 3,700 kilometers an hour. The Moon is in synchronous rotation with Earth - it is always shows Earth the same side. The Moon’s surface is dark. The dark side of the Moon cools to about -169 degrees Celsius. During the lunar day that lasts about a month Moon's surface bakes in the sun at up to 117 degrees Celsius. The Moon is drifting away from the Earth approx. 3.8 cm every year. The Moon has quakes called the Moonquakes. There is water on the Moon. The Soviet Union’s Luna program featured the first successful landing of an unmanned spacecraft on the surface of the Moon in 1966. The USA’s NASA Apollo 11 mission in 1969 was the first manned Moon landing. The first person to set foot on the Moon was Neil Armstrong. A lunar eclipse occurs when the Earth is between the Sun and the Moon. The Moons is actually more of an oval shape. The Moon is international property. Apollo 17 astronaut Harrison Schmitt was allergic to the Moon. Astronauts have brought 842 pounds of moon material back to Earth. The dark spots on the moon are called maria.

A world first. New footage from Mars rendered in stunning 4K resolution. We also talk about the cameras on board the Martian rovers and how we made the video. The cameras on board the rovers were the height of technology when the respective missions launched. A question often asked is: ‘Why don’t we actually have live video from Mars?’ Although the cameras are high quality, the rate at which the rovers can send data back to earth is the biggest challenge. Curiosity can only send data directly back to earth at 32 kilo-bits per second. Instead, when the rover can connect to the Mars Reconnaissance Orbiter, we get more favourable speeds of 2 Megabytes per second. However, this link is only available for about 8 minutes each Sol, or Martian day. As you would expect, sending HD video at these speeds would take a long long time. As nothing really moves on Mars, it makes more sense to take and send back images.

These high-res time-lapse sequences captured by astronauts aboard the International Space Station give us a beautiful and clear view of some well-known coastlines and countries around the world. Get a good look at England, France, Italy, Egypt, Algeria, Tunisia, Greece, the island of Crete, Taiwan, South Korea, Japan, the United States, Mexico, Ecuador, Peru, Chile, Argentina, Cuba, and more. We've attempted to show as many countries as we would, but inevitably we've left many out. Please write to the the astronaut photography office at NASA's Johnson Space Center to request inclusion in this amazing series of sequences.

Before modern telescopes, humans could only imagine what the surface of the sun and the planets looked like. Now advanced technology has made it possible to get in close, and take images of the Sun and the planets deep in our solar system. Now get ready to see the solar system as you’ve never seen it before, and see images that were so good they shocked astronomers

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents the dance of the ultra-hot material on our life-giving star in extraordinary detail, offering an intimate view of the grand forces of the solar system.
