A new era of human spaceflight is about to begin. American astronauts will once again launch on an American rocket from American soil to the International Space Station as part of our Commercial Crew Program! NASA astronauts Bob Behnken and Doug Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:32 p.m. EDT May 27, from Kennedy Space Center in Florida, for an extended stay at the space station for the Demo-2 mission.
As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.
Behnken and Hurley were among the first astronauts to begin working and training on SpaceX’s next-generation human space vehicle and were selected for their extensive test pilot and flight experience, including several missions on the space shuttle.
Behnken will be the joint operations commander for the mission, responsible for activities such as rendezvous, docking and undocking, as well as Demo-2 activities while the spacecraft is docked to the space station.
Hurley will be the spacecraft commander for Demo-2, responsible for activities such as launch, landing and recovery.
Lifting off from Launch Pad 39A atop a specially instrumented Falcon 9 rocket, Crew Dragon will accelerate its two passengers to approximately 17,000 mph and put it on an intercept course with the International Space Station. In about 24 hours, Crew Dragon will be in position to rendezvous and dock with the space station. The spacecraft is designed to do this autonomously but astronauts aboard the spacecraft and the station will be diligently monitoring approach and docking and can take control of the spacecraft if necessary.
The Demo-2 mission will be the final major step before our Commercial Crew Program certifies Crew Dragon for operational, long-duration missions to the space station. This certification and regular operation of Crew Dragon will enable NASA to continue the important research and technology investigations taking place onboard the station, which benefits people on Earth and lays the groundwork for future exploration of the Moon and Mars starting with the agency’s Artemis program, which will land the first woman and the next man on the lunar surface in 2024.

How hard is it to become an austronaut? I want to start to studie astrophysics and I don't know if I'll ever get any kind of job. Do you have any tips for people like me?
Astrophysics is a perfect field for pursuing any work at NASA! A degree in a STEM field is a requirement of becoming an astronaut, but other than that there are many possibilities. One of the best things about the astronaut office is its diversity. We are scientists, engineers, military pilots, flight test engineers, medical doctors, etc. etc. My biggest tip is to ensure you are pursuing what it is you are passionate about as that’s the only way to truly become exceptional at what you are doing, and most importantly, to be happy doing it. Passion, hard work, and dedication will get you there. Good luck!
Using a sustainable architecture and sophisticated hardware unlike any other, the first woman and the next man will set foot on the surface of the Moon by 2024. Artemis I, the first mission of our powerful Space Launch System (SLS) rocket and Orion spacecraft, is an important step in reaching that goal.
As we close out 2019 and look forward to 2020, here’s where we stand in the Artemis story — and what to expect in 2020.
The Artemis I Orion spacecraft arrived at our Plum Brook Station in Sandusky, Ohio, on Tuesday, Nov. 26 for in-space environmental testing in preparation for Artemis I.
This four-month test campaign will subject the spacecraft, consisting of its crew module and European-built service module, to the vacuum, extreme temperatures (ranging from -250° to 300° F) and electromagnetic environment it will experience during the three-week journey around the Moon and back. The goal of testing is to confirm the spacecraft’s components and systems work properly under in-space conditions, while gathering data to ensure the spacecraft is fit for all subsequent Artemis missions to the Moon and beyond. This is the final critical step before the spacecraft is ready to be joined with the Space Launch System rocket for this first test flight in 2020!
On Dec. 9, we welcomed members of the public to our Michoud Assembly Facility in New Orleans for #Artemis Day and to get an up-close look at the hardware that will help power our Artemis missions. The 43-acre facility has more than enough room for guests and the Artemis I, II, and III rocket hardware! NASA Administrator Jim Bridenstine formally unveiled the fully assembled core stage of our SLS rocket for the first Artemis mission to the Moon, then guests toured of the facility to see flight hardware for Artemis II and III. The full-day event — complete with two panel discussions and an exhibit hall — marked a milestone moment as we prepare for an exciting next phase in 2020.
Once engineers and technicians at Michoud complete functional testing on the Artemis I core stage, it will be rolled out of the Michoud factory and loaded onto our Pegasus barge for a very special delivery indeed. About this time last year, our Pegasus barge crew was delivering a test version of the liquid hydrogen tank from Michoud to NASA’s Marshall Space Flight Center in Huntsville for structural testing. This season, the Pegasus team will be transporting a much larger piece of hardware — the entire core stage — on a slightly shorter journey to the agency’s nearby Stennis Space Center near Bay St. Louis, Mississippi.
Why Stennis, you ask? The giant core stage will be locked and loaded into the B2 Test Stand there for the landmark Green Run test series. During the test series, the entire stage, including its extensive avionics and flight software systems, will be tested in full. The series will culminate with a hot fire of all four RS-25 engines and will certify the complex stage “go for launch.” The next time the core stage and its four engines fire as one will be on the launchpad at NASA’s Kennedy Space Center in Florida.
As Orion and SLS make progress toward the pad for Artemis I, employees at NASA centers and large and small companies across America are hard at work assembling and manufacturing flight hardware for Artemis II and beyond. The second mission of SLS and Orion will be a test flight with astronauts aboard that will go around the Moon before returning home. Our work today will pave the way for a new generation of moonwalkers and Artemis explorers.

With tumultuous winds peaking at 400 mph, the Great Red Spot has been swirling wildly over Jupiter’s skies for at least 150 years and possibly much longer. People saw a big spot on Jupiter as early as the 1600s when they started stargazing through telescopes, though it’s unclear whether they were looking at a different storm. Today, scientists know the Great Red Spot has been there for a while, but what causes its swirl of reddish hues remains to be discovered. More >
Despite its unofficial name, the Little Red Spot is about as wide as Earth. The storm reached its current size when three smaller spots collided and merged in the year 2000. More >
The planet’s rings might get most of the glory, but another shape’s been competing for attention: the hexagon. This jet stream is home to a massive hurricane tightly centered on the north pole, with an eye about 50 times larger than the average hurricane eye on Earth. Numerous small vortices spin clockwise while the hexagon and hurricane spin counterclockwise. The biggest of these vortices, seen near the lower right corner of the hexagon and appearing whitish, spans about 2,200 miles, approximately twice the size of the largest hurricane on Earth. More>
A tempest erupted in 2010, extending approximately 9,000 miles north-south large enough to eventually eat its own tail before petering out. The storm raged for 200 days, making it the longest-lasting, planet-encircling storm ever seen on Saturn. More >
Better cover your eyes. Dust storms are a frequent guest on the Red Planet, but one dust storm in 2001 larger by far than any seen on Earth raised a cloud of dust that engulfed the entire planet for three months. As the Sun warmed the airborne dust, the upper atmospheric temperature rose by about 80 degrees Fahrenheit. More >
Several large, dark spots on Neptune are similar to Jupiter’s hurricane-like storms. The largest spot, named the “Great Dark Spot” by its discoverers, contains a storm big enough for Earth to fit neatly inside. And, it looks to be an anticyclone similar to Jupiter’s Great Red Spot. More >
Not to be confused with Earth’s tornadoes, a stalk-like prominence rose up above the Sun, then split into about four strands that twisted themselves into a knot and dispersed over a two-hour period. This close-up shows the effect is one of airy gracefulness. More >
The storm blew across the equatorial region of Titan, creating large effects in the form of dark and likely “wet” from liquid hydrocarbons areas on the surface of the moon. The part of the storm visible here measures 750 miles in length east-to-west. The wings of the storm that trail off to the northwest and southwest from the easternmost point of the storm are each 930 miles long. More >
On March 9, 1989, a huge cloud of solar material exploded from the sun, twisting toward Earth. When this cloud of magnetized solar material called a coronal mass ejection reached our planet, it set off a chain of events in near-Earth space that ultimately knocked out an entire power grid area to the Canadian province Quebec for nine hours. More >
Back on Earth, Typhoon Tip of 1979 remains the biggest storm to ever hit our planet, making landfall in Japan. The tropical cyclone saw sustained winds peak at 190 mph and the diameter of circulation spanned approximately 1,380 miles. Fortunately, we now have plans to better predict future storms on Earth. NASA recently launched a new fleet of hurricane-tracking satellites, known as the Cyclone Global Navigation Satellite System (CYGNSS), which will use the same GPS technology you and I use in our cars to measure wind speed and ultimately improve how to track and forecast hurricanes.

Targeted for launch to the Red Planet in July 2020, our Mars 2020 Perseverance rover will search for signs of ancient life. Mission engineer Lauren DuCharme and astrobiologist Sarah Stewart Johnson will be taking your questions in an Answer Time session on Friday, July 17 from noon to 1pm ET here on our Tumblr! Make sure to ask your question now by visiting http://nasa.tumblr.com/ask
Lauren DuCharme is a systems engineer at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, where she’s working on the launch and cruise of the Perseverance rover. Lauren got her start at JPL as an intern. Professor Sarah Stewart Johnson is an astrobiologist at Georgetown University in Washington. Her research focuses on detecting biosignatures, or traces of life, in planetary environments.
The name Perseverance was chosen from among the 28,000 essays submitted during the "Name the Rover" contest. Seventh-grader Alex Mather wrote in his winning essay, "We are a species of explorers, and we will meet many setbacks on the way to Mars. However, we can persevere. We, not as a nation but as humans, will not give up."
Perseverance will land in Jezero Crater, a 28-mile-wide (45-kilometer-wide) crater that scientists believe was once filled with water.
Perseverance carries instruments and technology that will pave the way for future human missions to the Moon and Mars. It is also carrying 23 cameras and two microphones to the Red Planet — the most ever flown in the history of deep-space exploration.
Perseverance is the first leg of a round trip to Mars. It will be the first rover to bring a sample caching system to Mars that will package promising samples for return to Earth by a future mission.

Check out features of our feline friends that have come to life as interstellar phenomena!
Pictured first, the Cat’s Paw Nebula is located about 4,200-5,500 light-years from Earth – situated in our very own Milky Way Galaxy. It was named for the large, round features that create the impression of a feline footprint and was captured by our Spitzer Space Telescope. After gas and dust inside the nebula collapse to form stars, the stars may in turn heat up the pressurized gas surrounding them. This process causes the gas to expand into space and form the bright red bubbles you see. The green areas show places where radiation from hot stars collided with large molecules called "polycyclic aromatic hydrocarbons," causing them to fluoresce.
Next, you’ll find the Cat’s Eye Nebula. Residing 3,000 light-years from Earth, the Cat’s Eye represents a brief, yet glorious, phase in the life of a sun-like star. This nebula's dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. To create this view, Hubble Space Telescope archival image data have been reprocessed. Compared to well-known Hubble pictures, the alternative processing strives to sharpen and improve the visibility of details in light and dark areas of the nebula and also applies a more complex color palette. Gazing into the Cat's Eye, astronomers may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution ... in about 5 billion years.

6th grade South Lamar student, Alexis S., asked, " How old are you & how many hours a day do you train to be ready for space?"
I am 46 years old, but I don’t feel like I’m 46 because I have the best job in the world. I train everyday at least 8 hours, and even on the weekends I’m constantly thinking about work.
How much rain falls in a hurricane? How much snow falls in a nor’easter? What even is a nor’easter? These are the sorts of questions answered by our Global Precipitation Measurement Mission, or GPM.
GPM measures precipitation: Rain, snow, sleet, freezing rain, hail, ice pellets. It tells meteorologists the volume, intensity and location of the precipitation that falls in weather systems, helping them improve their forecasting, gather information about extreme weather and better understand Earth’s energy and water cycles.
And putting all that together, one of GPM’s specialties is measuring storms.
GPM is marking its fifth birthday this year, and to celebrate, we’re looking back on some severe storms that the mission measured in its first five years.
1. The Nor’easter of 2018
A nor’easter is a swirling storm with strong northeasterly winds and often lots of snow. In January 2018, the mission’s main satellite, the Core Observatory, flew over the East Coast in time to capture the development of a nor’easter. The storm dumped 18 inches of snow in parts of New England and unleashed winds up to 80 miles per hour!
2. Hurricane Harvey
Hurricane Harvey came to a virtual halt over eastern Texas in August 2017, producing the largest rain event in U.S. history. Harvey dropped up to 5 feet of rain, causing $125 billion in damage. The Core Observatory passed over the storm several times, using its radar and microwave instruments to capture the devastating deluge.
3. Typhoon Vongfong
In October 2014, GPM flew over one of its very first Category 5 typhoons – tropical storms with wind speeds faster than 157 miles per hour. The storm was Typhoon Vongfong, which caused $48 million in damage in Japan, the Philippines and Taiwan. We were able to see both the pattern and the intensity of Vongfong’s rain, which let meteorologists know the storm’s structure and how it might behave.
4. Near Real-Time Global Precipitation Calculations
The Core Observatory isn’t GPM’s only satellite! A dozen other satellites from different countries and government agencies come together to share their microwave measurements with the Core Observatory. Together, they are called the GPM Constellation, and they create one of its most impressive products, IMERG.
IMERG stands for “Integrated Multi-satellitE Retrievals for GPM,” and it uses the info from all the satellites in the Constellation to calculate global precipitation in near real time. In other words, we can see where it’s raining anywhere in the world, practically live.
5. Hurricane Ophelia
Hurricane Ophelia hit Ireland and the United Kingdom in October 2017, pounding them with winds up to 115 miles per hour, reddening the skies with dust from the Sahara Desert and causing more than $79 million in damages. Several satellites from the Constellation passed over Ophelia, watching this mid-latitude weather system develop into a Category 3 hurricane – the easternmost Category 3 storm in the satellite era (since 1970).
From the softest snow to the fiercest hurricanes, GPM is keeping a weather eye open for precipitation around the world. And we’re on cloud nine about that.

Does space have a standard time or do you rely on the time zones on Earth while you are in space?
Great question. Really it is up to the particular space agency/mission which time zone they use. For example, since the International Space Station is a collaboration between NASA, the Russian Space Agency, the European Space Agency, the Japanese Space Agency, and the Canadian Space Agency, we came up with the compromise of operating on Greenwich Mean Time (GMT). So, Space Station time is the same as London time! The International Space Station orbits our planet every 90 minutes, so of course we’re transiting across multiple time zones constantly.
Does all capsules drops in Kazakhstan on return after every mission?
Since the US Space Shuttle retired in 2011, we launch to and return from the Space Station with the Russian Space Agency. So yes, these capsules (the Soyuz) land in Kazakhstan (or surrounding regions). However, different spacecrafts have different reentry trajectories, depending on where they aim to land. As you might recall, the Apollo mission capsules landed in the ocean. Since Space-X and Boeing are currently building new vehicles so that we will also launch from the US again to get to the International Space Station, these spacecraft will return to the US. For example, you may have seen footage of Space-X cargo vehicles splashing down into the Pacific over the last few years. The Boeing Starliner plans to land on land instead of water. NASA is also currently building the Orion spacecraft, which will take us to destinations beyond low earth orbit (where the Space Station is), whether that be the Moon or Mars or another target. Orion will also splash down in the ocean.
