Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions:
Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.
“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

+NASA AMA: We just sequenced DNA in space for the first time. Ask us anything!
We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation, which is a partnership between CASIS and Eli Lilly Co. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Learn more about what we and our partners are doing:

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

Kate and her crew mates have also worked on the combustion experiments.
Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.
Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.
The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions. Read more about the experiment:
+Plant RNA Harvest
NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.

Could you theoretically time travel through a black hole or other object with such intense mass?
With 2016 behind us, we take the time to not only reflect on what we’ve accomplished, but also take a look to what’s ahead for the next year.
New Telescope in Town
This year marked big progress on our James Webb Space Telescope and there are still a number of large milestones before the telescope is launched in 2018. Once launched, JWST will be the premier observatory of the next decade. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own solar system.
In 2017, the telescope will be shipped to our Johnson Space Center in Houston, Texas where end-to-end optical testing in a simulated cryo-temperature and vacuum space environment will occur.
Epic Final Year at Saturn
After more than 12 years studying Saturn, its rings and moons, our Cassini spacecraft is in its final year of its epic voyage. The conclusion of the historic scientific odyssey is planned for September 2017, but not before the spacecraft completes a daring two-part endgame.
Cassini’s final phase – called the Grand Finale – begins in earnest in April 2017. During this time, Cassini will make the closest-ever observations of Saturn, mapping the planet’s magnetic and gravity fields with exquisite precision and returning ultra-close views of the atmosphere.
Delivering Supplies to Space
Our ambitious commercial space program has enabled a successful partnership with two American companies to resupply the International Space Station.
The companies are successfully resupplying the space station, and more missions to deliver scientific investigations and cargo are planned for 2017.
Launching Two Earth Missions
New Earth science missions got underway in 2016 to enable studies that will unravel the complexities of our planet from the highest reaches of Earth’s atmosphere to its core. In 2017, we will launch two Earth-observing instruments to the International Space Station as part of our ongoing use of the orbiting space laboratory to study our changing planet.
The Stratospheric Aerosol and Gas Experiment III (SAGE III) will give us a new way to monitor Earth’s protective ozone layer and document its ongoing recovery. The Lightning Imaging Sensor (LIS) will measure both in-cloud and cloud-to-ground lightning over much of the planet, data that will help improve our understanding of lightning’s connections to weather and related phenomena.
Commercial Crew
Our Commercial Crew Program is working with American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station.
In 2017, astronauts will train for commercial flights and launch pad 39A will be completed at Kennedy Space Center in Florida. Work is wrapping up on a new structure built specifically for the needs of astronauts climbing into Boeing's CST-100 Starliner as it stands atop a United Launch Alliance Atlas V rocket at Space Launch Complex 41 in Florida. In 2017, the 200-foot-tall Crew Access Tower and Crew Access Arm will see installation and testing of emergency evacuation systems.
SpaceX has also overhauled the historic Launch Pad 39A at Kennedy and built new support structures for the company's line of Falcon rockets. The Crew Access Arm, currently under construction, will be connected in mid-2017 to provide a bridge from the fixed service structure to the Crew Dragon spacecraft so astronauts can board before launch
Orion Progress
Our Orion spacecraft is being built to take humans farther than they’ve ever gone before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities.
In 2017, computers in the Orion crew module for the spacecraft’s first mission with our Space Launch System rocket will be turned on for the first time to verify the spacecraft can route power and send commands. While the Orion outfitting and assembly process for the first mission of the spacecraft atop the SLS rocket continues in 2017, construction will also begin on the vehicle for the first Orion flight with astronauts that will fly as early as 2021.
Cutting Edge Technology
Our Space Technology office is dedicated to pushing the technological envelope, taking on challenges not only to further space agency missions near Earth, but also to sustain future deep space exploration activities.
In 2016, the office focused on and made significant progress in advancing technologies and capabilities that will continue into 2017.
Advances in Aeronautics
Our rich aeronautical research heritage added to its history of technical innovation in 2016 with advancements that will help make airplanes use less fuel, release fewer emissions and fly more quietly…and that includes working to return supersonic flight to the commercial marketplace.
We took steps in 2016 to resume designing, building and flying several experimental aircraft, or X-planes, as a means to demonstrate key green technologies and help accelerate their use by industry. In 2017, this research will continue to grow and develop.
Thanks for joining us in 2016, we look forward to sharing our progress with you in the coming year.

Our solar system is huge, let us break it down for you. Here are a few things to know this week:
1. The View from the Far Shore
The rugged shores of Pluto’s highlands come into sharp view in a newly released image from our New Horizons spacecraft. This latest view zooms in on the southeastern portion of Pluto’s great ice plains, where they border dark highlands formerly named Krun Macula.
2. Dawn’s Latest Light
Our Dawn mission has now completed more than 1,000 orbital revolutions since entering into Ceres’ gravitational grip in March 2015. The probe is healthy and performing its ambitious assignments impeccably. See what it has revealed lately HERE.
3. Counting Down
Our OSIRIS-REx mission to the asteroid Bennu is now entering the final preparations for its planned launch in September. In a new interview, the mission’s principal investigator reports on the final pre-flight tests happening at our Kennedy Space Center in Florida.
4. Deep Dive
Three successful engine maneuvers to bring the lowest part of the spacecraft’s orbit down to just 74 miles (119 km) above the surface of Mars, the MAVEN mission’s fifth deep dip campaign has begun. MAVEN is studying the planet’s atmosphere up close.
5. Storm Season
Meanwhile, other robotic Mars orbiters have revealed that a pattern of three large regional dust storms occurs with similar timing most Martian years. The seasonal pattern was detected from dust storms’ effects on atmospheric temperatures, which spacecraft have been monitoring since 1997.

I love astrophysics and especially black holes and I want to pursue a career on them, but to be honest I'm scared to be not good enough or not clever enough. How did you decide to work on black holes? How did you become the person you are today?
SpaceX is scheduled to launch its Dragon spacecraft PACKED with super cool research and technology to the International Space Station June 1 from Kennedy Space Center in Florida. New solar panels, investigations that study neutron stars and even fruit flies are on the cargo list. Let’s take a look at what other bits of science are making their way to the orbiting laboratory 250 miles above the Earth…
New solar panels to test concept for more efficient power source
Solar panels generate power well, but they can be delicate and large when used to power a spacecraft or satellites. This technology demonstration is a solar panel concept that is lighter and stores more compactly for launch than the solar panels currently in use.
Roll-Out Solar Array (ROSA) has solar cells on a flexible blanket and a framework that rolls out like a tape measure and snap into place, and could be used to power future space vehicles.
Investigation to Study Composition of Neutron Stars
Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, contain exotic states of matter that are impossible to replicate in any lab. NICER studies the makeup of these stars, and could provide new insight into their nature and super weird behavior.
Neutron stars emit X-ray radiation, enabling the NICER technology to observe and record information about its structure, dynamics and energetics.
Experiment to Study Effect of New Drug on Bone Loss
When people and animals spend lots of space, they experience bone density loss. In-flight exercise can prevent it from getting worse, but there isn’t a therapy on Earth or in space that can restore bone that is already lost.
The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.
Research to Understand Cardiovascular Changes
Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity.
The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart. Fruit flies are effective model organisms, and we don’t mean on the fashion runway. Want to see how 1,000 bottles of fruit flies were prepared to go to space? Check THIS out.
Space Life-Support Investigation
Currently, the life-support systems aboard the space station require special equipment to separate liquids and gases. This technology utilizes rotating and moving parts that, if broken or otherwise compromised, could cause contamination aboard the station.
The Capillary Structures investigation studies a new method of water recycling and carbon dioxide removal using structures designed in specific shapes to manage fluid and gas mixtures.
Earth-Observation Tools
Orbiting approximately 250 miles above the Earth’s surface, the space station provides pretty amazing views of the Earth. The Multiple User System for Earth Sensing (MUSES) facility hosts Earth-viewing instruments such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations.
This investigation can produce data that could be used for maritime domain awareness, agricultural awareness, food security, disaster response, air quality, oil and gas exploration and fire detection.

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s.
Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane.
Heat and the energy it carries are what drive our planet: winds, weather, droughts, floods, and more are expressions of heat. The right amount of heat is even one of the things that makes life on Earth possible. But too much heat is changing the way our planet’s systems act.
Higher temperatures drive longer, more intense fire seasons. As rain and snowfall patterns change, some regions are getting drier and more vulnerable to damage, setting the stage for more fires.
2020 saw several record-breaking fires, both in Australia in the beginning of the year, and in the western U.S. through northern summer and fall. Smoke from fires in both regions reached so high into the atmosphere that it formed clouds and continues to travel around the globe today.
In the Siberian Arctic, unusually high temperatures helped drive at least 19 fires in the region. More than half of them were burning peat soil -- decomposed organic materials -- that stores a lot of carbon. Peat fires release vast amounts of carbon into the atmosphere, potentially leading to even more warming.
It wasn’t just fire seasons setting records. 2020 had more named tropical storms in the Atlantic and more storms making landfall in the U.S. than any hurricane season on record.
Hurricanes rely on warm ocean water as fuel, and this year, the Atlantic provided. 30 named storms weren’t the only things that made this year’s hurricane season notable.
Storms like Eta, Delta, and Iota quickly changed from smaller, weaker tropical storms into more destructive hurricanes. This rapid intensification is complicated, but it’s likely that warmer, more humid weather -- a result of climate change -- helps drive it.
Add enough heat, and even the biggest chunk of ice will melt. That’s true whether we’re talking about the ice cubes in your glass or the vast sheets of ice at our planet’s poles. Right now, the Arctic region is warming about three times faster than the rest of our planet, which has some major effects both locally and globally.
This year, Arctic sea ice hit a near-record low. Sea ice is actually made of frozen ocean water, and it grows and thaws with the seasons, typically reaching an annual minimum extent in September.
Warmer ocean water led to more ice melting this year, and 2020’s annual minimum extent continued a long trend of shrinking Arctic sea ice extent.
We study Earth and how it’s changing from the ground, the sky, and space. Using data from sensors all around the planet, we calculate the global average temperature, working with our partners at NOAA.
Many other organizations also track global temperature using their own instruments and methods, and they all match remarkably well. The last seven years were the hottest seven years on record. Earth is getting warmer.
We also study the effects of increasing temperatures, like the melting sea ice and longer fire seasons mentioned above. Additionally, we can study the cause of climate change from space, with a bird’s eye view of increasing carbon in the atmosphere.
The planet is changing because of human activities. We’re working together with other agencies to monitor changes and understand what this means for people in the future.

The Moon, Mars and Saturn form a pretty triangle in early April, the Lyrid Meteors are visible in late April, peaking high overhead on the 22nd.
You won't want to miss red Mars and golden Saturn in the south-southeast morning skies this month. Mars shines a little brighter than last month.
By the 7th, the Moon joins the pair. From a dark sky you may see some glow from the nearby Milky Way.
Midmonth, start looking for Lyrid meteors, which are active from April 14 through the 30th. They peak on the 22nd.
The Lyrids are one of the oldest known meteor showers and have been observed for 2,700 years. The first recorded sighting of a Lyrid meteor shower goes back to 687 BC by the Chinese. The pieces of space debris that interact with our atmosphere to create the Lyrids originate from comet C/1861 G1 Thatcher. Comet Thatcher was discovered on 5 April 1861 by A. E. Thatcher.
In the early morning sky, a patient observer will see up to more than a dozen meteors per hour in this medium-strength shower, with 18 meteors per hour calculated for the peak. U.S. observers should see good rates on the nights before and after this peak.
A bright first quarter moon plays havoc with sky conditions, marring most of the typically faint Lyrid meteors. But Lyra will be high overhead after the moon sets at midnight, so that's the best time to look for Lyrids.
Jupiter will also be visible in the night sky this month!
Through a telescope, Jupiter's clouds belts and zones are easy to see.
And watch the Great Red Spot transit--or cross--the visible (Earth-facing) disk of Jupiter every 8 hours.
Our Juno spacecraft continues to orbit this gas giant, too!
And Juno's JunoCam citizen science team is creating exciting images of Jupiter's features based on the latest spacecraft data.
Next month Jupiter is at opposition--when it rises at sunset, sets at sunrise, and offers great views for several months!

As Neil Armstrong became the first human to step foot onto another world on July 20, 1969, lunar dust collected on the boots of his spacesuit. He peered through the gold coating of his visor and looked out across the surface of the Moon, an entirely different landscape than he was used to.
Now, just in time for the 50th anniversary of the Moon landing, you can experience the boots that stepped in Moon dust and the visor that saw the moonscape up close. Neil Armstrong’s spacesuit from the historic Apollo 11 Moon landing is on display for the first time in 13 years in its new display case in the Wright Brothers & the Invention of the Aerial Age Gallery of the National Air and Space Museum.
This week, you can also watch us salute our Apollo 50th heroes and look forward to our next giant leap for future missions to the Moon and Mars. Tune in to a special two-hour live NASA Television broadcast at 1 p.m. ET on Friday, July 19. Watch the program at www.nasa.gov/live.

This month binoculars will come in handy--to view the moon, star clusters, and a close pairing of Venus and Jupiter.
You can’t miss bright Venus in the predawn sky. This month Venus pairs up with Jupiter on the morning of November 13th.
The Leonids peak on a moonless November 17th. Expect no more than 10 meteors an hour around 3:00 a.m., the height of the shower.
The Northern and Southern sub-branches of the Taurid meteor shower offer sparse counts of about 5 meteors per hour, but slow, bright meteors are common.
The nearby November Orionids peak on the 28th. In contrast to the Taurids, the Orionids are swift. But don’t expect more than 3 meteors per hour.
The moon glides by three beautiful star clusters in the morning sky this month, and a pair of binoculars will allow you to see the individual stars in the clusters. Aim your binoculars at the Pleiades and the moon on the 5th.
Then aim at the Messier or M-35 cluster and the moon on the 7th and the Beehive cluster and the moon on the 10th.
Meanwhile, at dusk, catch Saturn as it dips closer to the western horizon and pairs up with Mercury on the 24th through the 28th.
Also, Comet C/2017 O1 should still be a binocular-friendly magnitude 7 or 8 greenish object in November. Use Polaris, the North Star as a guide. Look in the East to Northeast sky in the late evening.
