In February 2020, NASA’s Solar Dynamics Observatory (SDO) will celebrate its 10th year in space. Over the past decade, the spacecraft has kept a constant eye on the Sun, studying how the Sun creates solar activity and drives space weather—tthe dynamic conditions in space that impact the entire solar system, including Earth. Since its launch on Feb. 11, 2010, SDO has collected millions of scientific images of our nearest star, giving scientists new insights into its workings. SDO’s measurements of the sun from the interior to the atmosphere, magnetic field, and energy output—have greatly contributed to our understanding of our closest star. SDO’s images have also become iconic. If you’ve ever seen a close-up of activity on the Sun, it was likely from an SDO image.

Far, far beyond the orbits of the planets lie the hazy outlines of the magnetic bubble in space that we call home. This is the heliosphere, the vast bubble that is generated by the Sun’s magnetic field and envelops all the planets. The borders of this cosmic bubble are not fixed. In response to the Sun’s gasps and sighs, they shrink and stretch over the years. Now, for the first time, scientists have used an entire solar cycle of data from NASA’s IBEX spacecraft to study how the heliosphere changes over time. Solar cycles last roughly 11 years, as the Sun swings from seasons of high to low activity and back to high again. With IBEX’s long record, scientists were eager to examine how the Sun’s mood swings play out at the edge of the heliosphere. The results show the shifting outer heliosphere in great detail, deftly sketch the heliosphere’s shape—aa matter of debate in recent years—and hint at the processes behind one of its most puzzling features. These findings, along with a newly fine-tuned data set, are published in The Astrophysical Journal Supplements on June 10, 2020.

One of the most frequent questions we get about life on Space Station is how to us the toilet… Here’s a quick look at the answer!

The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth’s and roasted by temperatures two times hotter than an oven. But was it always that way? Could Venus once have been a twin of Earth — a habitable world with liquid water oceans? This is one of the many mysteries associated with our shrouded sister world. 27 years have passed since NASA’s Magellan mission last orbited Venus. That was NASA’s most recent mission to Earth’s sister planet, and while we have gained significant knowledge of Venus since then, there are still numerous mysteries about the planet that remain unsolved. NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission hopes to change that.

The DAVINCI+ mission concept under consideration by NASA Headquarters officials for flight to Venus in 2026 as part of the Discovery Program includes a passionate band of women and men who have been striving to return NASA and the U.S. to Venus' atmosphere for a decade. Some of these DAVINCI+ team-mates were captured on video talking about their visions of Venus and why our mission was named for Leonardo da Vinci. A short medley of DAVINCI+ team members, including the two Deputy PI’s, the Project Science team, and key scientists, demonstrate why Venus is such a compelling target today in 2021. Venus, here we come."

Inspired by the Renaissance vision of Leonardo da Vinci, NASA is presently preparing its scientific return to Venus’ atmosphere and surface with a mission known as the “Deep Atmosphere of Venus Investigation of Noble Gases, Chemistry, and Imaging” (DAVINCI). The DAVINCI mission will “take the plunge” into Venus’ enigmatic history using an instrumented deep atmosphere probe spacecraft that will carry five instruments for measuring the chemistry and environments throughout the clouds and to the surface while also conducting the first descent imaging of a mountain system on Venus known as Alpha Regio, which may represent an ancient continent. In addition, the DAVINCI mission includes two science flybys of Venus, during which it will search for clues to mystery molecules in the upper cloud deck while also measuring the rock types in some of Venus highland regions. All of these new and unique measurements will make the ‘exoplanet next door a key place for understanding Earth- and Venus-sized exoplanets that may have similar histories to our sister planet. DAVINCI will pave the way for a series of missions by NASA and ESA in the 2030’s by opening the frontier as it searches for clues to whether Venus harbored oceans and how its atmosphere-climate system evolved over billions of years. DAVINCI’s science will address questions about habitability and how it could be “lost” as rocky planets evolve over time. NASA’s Goddard Space Flight Center leads the DAVINCI Mission as the PI institution.

Launching in 2029, NASA’s Deep Atmosphere Venus Investigation of Noble Gases, Chemistry, and Imaging (DAVINCI) mission will bring a rich suite of instruments to Venus to address long-standing questions about Earth’s sister planet. Some scientists think Venus may once have been more Earth-like in the past, with oceans and pleasant surface temperatures. DAVINCI data will help us determine if this intriguing possibility is true. Clues to Venus’ mysterious past may be hidden in atmospheric gases or in surface rocks formed in association with ancient water in the planet’s mountainous highlands. During two flybys, the DAVINCI carrier, relay, and imaging spacecraft will collect data on the planet’s day side of unknown compounds that absorb ultraviolet light in the Venus upper atmosphere with an instrument called the Compact Ultraviolet to Visible Imaging Spectrometer (CUVIS); on the planet’s night side, the Venus Imaging System for Observational Reconnaissance (VISOR) will sense heat from Venus’ surface emerging from beneath the clouds to help us better understand the composition of diverse geological highlands regions across Venus. VISOR will also study clouds on Venus day side in the ultraviolet, producing cloud motion movies. Venus has a scorching surface hotter than your home oven and a complex atmosphere 90 times thicker than Earth's, made mostly of carbon dioxide and sulfuric acid clouds. Two years after launch, the DAVINCI descent sphere will be dropped by the carrier spacecraft into this extreme environment to provide new direct measurements of the Venus atmosphere and reveal a bird's-eye view of the surface below the clouds. The descent location, the Alpha Regio “tessera,” is a mountainous highland region whose rocks may hold clues to the planet’s mysterious past. The titanium sphere is designed to withstand the harsh conditions of the Venusian environment while protecting the instruments nestled inside. The Venus Tunable Laser Spectrometer (VTLS) will measure key gases that offer clues to the planet’s past, including compounds that may hint at the possible history of past water. The Venus Mass Spectrometer (VMS) will study the atmosphere in detail, including noble gases and trace gases, from 67 km to the near surface. The Venus Atmospheric Structure Investigation (VASI) will measure pressure, temperature, and winds throughout the descent. Peering through a transparent sapphire window at the bottom of the descent sphere, the Venus Descent Imager (VenDI) will map the 3-D topography and composition of Alpha Regio, with topographic resolution at up to sub-meter scales. Lastly, a student collaboration experiment called the Venus Oxygen Fugacity Experiment (VfOx) will be mounted to the probe to measure oxygen in the deep atmosphere. Together, this set of data will help rewrite the textbooks on Venus and may even help us better understand Venus-like planets in other solar systems. DAVINCI is a partnership between NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Lockheed Martin in Denver, Colorado, with instruments from NASA Goddard, the Jet Propulsion Laboratory, Malin Space Science Systems, and key supporting hardware from the Johns Hopkins Applied Physics Laboratory and the University of Michigan.

NASA has selected the DAVINCI+ (Deep Atmosphere Venus Investigation of Noble Gases, Chemistry, and Imaging +) mission as part of its Discovery program, and it will be the first spacecraft to enter the Venus atmosphere since NASA’s Pioneer Venus in 1978 and the USSR’s Vega in 1985. Named for the visionary Renaissance artist and scientist Leonardo da Vinci, the DAVINCI+ mission will bring 21st-century technologies to the world next door. DAVINCI+ may reveal whether Earth’s sister planet looked more like Earth’s twin planet in a distant, possibly hospitable past with oceans and continents. The mission combines a spacecraft, developed by Lockheed-Martin, and a descent probe, developed at NASA’s Goddard Space Flight Center. The spacecraft will map the cloud motions and surface composition of mountainous regions, including the Australia-sized Ishtar Terra. The descent probe will take a daring hour-long plunge through the massive and largely unexplored atmosphere to the surface, making detailed measurements of the atmosphere and surface the whole way down. These measurements include atmospheric samples and images that will allow scientists to deduce the planet’s history, its possible watery past, and trace gases as fingerprints of the planet’s inner workings. The probe will descend over Alpha Regio, an intriguing highland terrain known as a “tessera” standing nearly 10,000 feet tall above the surrounding plains, which might be a remnant of an ancient continent. All of these measurements will help connect Earth’s next-door neighbor to similar planets orbiting other stars that may be observed with the James Webb Space Telescope. The DAVINCI+ team spans NASA centers (Goddard Space Flight Center, Jet Propulsion Laboratory, Langley Research Center, and Ames Research Center), aerospace partners (Lockheed Martin), and Universities (University of Michigan) to deliver ground-breaking science during the late 2020’s and early 2030s, with a launch in 2029, flybys of Venus in 2030, and probe-based measurements in June 2031. The information sent back to Earth will rewrite textbooks and inspire the next generation of planetary scientists. The NASA Goddard-led team includes Principal Investigator Jim Garvin and Deputy Principal Investigators Stephanie Getty and Giada Arney, as well as Project Manager Ken Schwer, lead Systems Engineer Michael Sekerak, and many others at Goddard, Lockheed Martin, and other institutions. The team is excited to return NASA to Venus to address our sister planet’s long-standing mysteries!

The Deep Atmosphere Venus Investigation of Noble gases, Chemistry and Imaging, or DAVINCI, mission will bring the best possible instrumentation to the massive Venus atmosphere to decipher its evolutionary history, the role of water perhaps as oceans, and how it may inform how we investigate exoplanets around nearby stars. Named in honor of the Renaissance visionary Leonardo da Vinci, this new NASA mission to Venus will send a meter-diameter “probe” to Venus in 2029 bristling with instruments that can measure the atmosphere and surface in ways not possible in the past 50 years of exploration, building off what has been successful at Mars on the Curiosity rover. DAVINCI’s transect of the Venus atmosphere from near the cloud tops to the surface in an ancient continental region known as Alpha Regio (more than two times the size of Texas) will put Venus into context relative to Earth and Mars. This will enable our sister planet Venus to contribute to the understanding of rocky, atmosphere-bearing exoplanets that will be explored by new Astrophysical observatories such as the James Webb Space Telescope (JWST). It will be 40+ years since humanity last visited Venus as of our time of probe entry in 2031. DAVINCI’s mission includes two compelling flybys of Venus prior to “taking the plunge” with the Probe spacecraft which will acquire video of cloud motions and search for clues to mystery chemical absorbers in the highest altitude clouds. The descent camera on DAVINCI will enable human-scale imaging of the enigmatic "tessera" highlands of Venus with direct information on composition and relief. These measurements will serve as a legacy for decades to come as other missions map Venus from orbit and prepare for an era of potentially astrobiological reconnaissance of our magical sister world. DAVINCI is a partnership between NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Lockheed Martin in Denver, Colorado, with instruments from NASA’s Goddard, Jet Propulsion Laboratory, Malin Space Science Systems, and key supporting hardware from Johns Hopkins Applied Physics Laboratory and the University of Michigan.
