There are millions of asteroids in our solar system, so why is NASA going to the asteroid Psyche? Scientists think this particular asteroid, which orbits the Sun between Mars and Jupiter, could be part of the metal-rich interior of a planetesimal, a building block of the rocky planets in our solar system. Visiting Psyche and studying it up close could help us understand how planets like Mercury, Venus, Earth, and Mars came to be. Join us on the journey to the first metal-rich asteroid humankind has ever visited. The Psyche mission is set to launch as early as Oct. 12, 2023. Watch live launch commentary at / nasa .

On December 9, 2020, Starship serial number 8 (SN8) completed a high-altitude flight test as it successfully ascended, transitioned propellant, and demonstrated a first-of-its-kind controlled aerodynamic descent and landing flip maneuver – which will enable landing where prepared surfaces or runways do not exist, including the Moon, Mars, and beyond.

On March 3, Starship serial number 10 (SN10) completed SpaceX’s third high-altitude flight test of a Starship prototype as it successfully ascended, transitioned propellant, and reoriented itself for reentry and an active aerodynamic controlled descent. SN10’s Raptor engines reignited to perform the vehicle’s landing flip maneuver immediately before successfully touching down on the landing pad. Test flights such as SN10’s are about improving our understanding and development of a fully reusable transportation system designed to carry both crew and cargo on long-duration interplanetary flights, and help humanity return to the Moon, and travel to Mars and beyond.

Starship gave us quite a show during the first flight test of a fully integrated Starship (S24) and Super Heavy rocket (B7) from Starbase in Texas. On April 20, 2023 at 8:33 a.m. CT, Starship successfully lifted off from the orbital launch pad for the first time. The vehicle cleared the pad and beach as Starship climbed to an apogee of ~39 km over the Gulf of Mexico – the highest of any Starship to-date. With a test like this, success comes from what we learn, and we learned a tremendous amount about the vehicle and ground systems today that will help us improve on future flights of Starship.

Aboard the International Space Station, Expedition 69 Flight Engineer Frank Rubio of NASA answered questions about life and work on the orbiting laboratory and discussed his record-breaking mission during an in-flight conversation recorded on Sept. 5 with NASA astronaut Mark Vande Hei who was in Mission Control at the Johnson Space Center. Rubio surpassed Vande Hei’s previous record for the longest single spaceflight by an American astronaut – 355 days – on Sept. 11. Rubio will wrap up his long duration flight on the station on Sept. 27 with a total of 371 days in space. Research conducted during long-duration missions such as this benefits people on Earth and lays the groundwork for future human exploration through the agency’s Artemis missions, which will send astronauts to the Moon to prepare for future expeditions to Mars.

NASA Astronaut Loral O’Hara launched to the International Space Station for the first time on Sept. 15 the Baikonur Cosmodrome in Kazakhstan. Her launch signifies a lifetime of dedication to exploration for O’Hara, who grew space-flown tomato seeds in the second grade, studied aerospace engineering in college, and even worked on scientific research vessels to study Earth’s oceans before coming to NASA. O’Hara will serve as an Expedition 69 and 70 flight engineer over the course of her six-month mission. During her stay at the orbiting laboratory, she’ll work on hundreds of science experiments across a variety of disciplines including biology, physics, and physiology. Get the latest updates from O’Hara as she shares her mission by following @LunarLoral on social media.

Human spaceflight is a team sport – and not everyone needs a Ph.D. to be a part of it. In Cosmic Careers, we explore the different, and sometimes unusual jobs needed to make NASA’s mission possible. We’re making a splash this episode with divers Emily Cox and Reilly Holmgreen. They work at NASA’s Neutral Buoyancy Laboratory and explain that if you want to work underwater with astronauts in training, all you need is a dive certification. The Neutral Buoyancy Lab is 40 foot deep pool where astronauts can train for spacewalks – the process of putting on a spacesuit and performing tasks out in the vacuum of space. Come along to the bottom of the pool with our host Dane Turner for a tour of the International Space Station’s mockups and the lunar terrain area that astronauts will use to practice working on the lunar surface through NASA’s Artemis program.

Our planet is beautiful. In honor of Earth Day 2017, enjoy Ultra High Definition views of our home planet captured from 250 miles up on the International Space Station! Fire up the biggest screen you have. Then kick back and watch. _______________________________________ FOLLOW THE SPACE STATION!

Watch the launch of the SpaceX CRS-10 mission in ultra-high definition/4K resolution! Liftoff took place Feb. 19, 2017, from Launch Complex 39A at NASA's Kennedy Space Center in Florida.

This time-lapse imagery taken by NASA astronaut Jack Fischer from the International Space Station in 4K Ultra High Defintion takes us over the Pacific Ocean’s moon glint and above the night lights of San Francisco, Calif. through Denver, Colo.

Got three minutes to spare for a tour of southern Europe? That’s all the time it takes, when you have a 4K camera orbiting Earth 250 miles up—and we do, on the International Space Station. This Ultra High Definition video was shot in August 2016 as the station traveled nearly 1000 miles, taking in views from above the western coast of France to the Iberian Peninsula, Italy, Switzerland, southern Germany and Austria, and southward to the countries of the Balkan Peninsula. Music by Joakim Karud.

NASA astronaut Scott Kelly, who marked day 300 of a historic year in space on Jan. 21, 2016, shows off another fascinating feature of life in microgravity. Kelly used two paddles with hydrophobic, or water repellant, features to pass a sphere of water back and forth. Scientists use the microgravity environment of the space station to advance scientific knowledge in Earth, space, physical, and biological sciences that otherwise wouldn't be possible down here on the planet. The paddles are polycarbonate laser etched so that the surfaces are actually arrays of 300 micrometer posts (0.3mm). The surfaces were then spray coated with a Teflon coat. The combined effects of surface roughness and non-wettability produce a super-hydrophobic surface capable of preventing water adhesion in dynamic processes. The larger the drop, the less force it takes to break it up. The smaller the drop, the harder you can hit it. Scott is demonstrating about a 4 mL drop (over 100 times larger than a rain drop).

Ever wonder what the spacewalker sees while you’re looking at him or her? Here’s your answer, courtesy of NASA astronaut Jack Fischer. This Ultra High Definition clip shows Fischer outside the International Space Station during a spacewalk on Expedition 51 in May 2017, and the view from a small camera attached to his spacesuit at the same time.

This visualization traverses the CANDELS Ultra Deep Survey (UDS) field to showcase the varied appearances of galaxies and their three-dimensional distribution. The sequence features a dense cluster of galaxies about 6 billion light-years away and extends to galaxies at more than twice that distance. Because the light from these galaxies has travelled for billions of years across space, the images show the galaxies as they appeared billions of years ago. In addition, the expansion of space has redshifted the light of these galaxies toward longer wavelengths (i.e., to the red end of the visible-light region and into the infrared-light region). The changes seen in galaxies during the fly-through illustrate the changes in galaxy structure and appearance over billions of years of cosmic history. CANDELS is an acronym for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey project. One of the largest projects ever done with the Hubble Space Telescope, CANDELS surveyed five fields to study the development of galaxies over time. The CANDELS observations of the UDS field complement ground-based observations from the United Kingdom Infrared Telescope. Astronomers and visual artists extracted over 26,000 galaxies from the Hubble UDS images and created a computer model based on the measured and estimated properties. Note that the distances used in the visualization are significantly compressed for cinematic purposes. Credits: NASA, ESA, F. Summers, J. DePasquale, G. Bacon, and Z.
