LAUREL, Md. — NASA’s Parker Solar Probe captured stunning views of Venus during its close flyby of the planet in July 2020.
Though Parker Solar Probe’s focus is the Sun, Venus plays a critical role in the mission: The spacecraft whips by Venus a total of seven times over the course of its seven-year mission, using the planet’s gravity to bend the spacecraft’s orbit. These Venus gravity assists allow Parker Solar Probe to fly closer and closer to the Sun on its mission to study the dynamics of the solar wind close to its source.
LITTLETON, Colo. (NASA PR) — With less than a year to launch, NASA’s Lucy mission’s third and final scientific instrument has been integrated onto the spacecraft.
The spacecraft, which will be the first to explore the Trojan asteroids — a population of small bodies that share an orbit with Jupiter — is in the final stages of the assembly process. Just five months ago, at the beginning of the Assembly, Testing and Launch operations (ATLO) process, the components of the Lucy spacecraft were being built all over the country. Today, a nearly assembled spacecraft sits in the high bay in Lockheed Martin Space in Littleton, Colorado.
GREENBELT, Md. (NASA PR) — NASA’s Lucy mission is one step closer to launch as L’TES, the Lucy Thermal Emission Spectrometer, has been successfully integrated on to the spacecraft.
“Having two of the three instruments integrated onto the spacecraft is an exciting milestone,” said Donya Douglas-Bradshaw, Lucy project manager from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The L’TES team is to be commended for their true dedication and determination.”
ASHINGTON (NASA PR) — NASA has approved two heliophysics missions to explore the Sun and the system that drives space weather near Earth. Together, NASA’s contribution to the Extreme Ultraviolet High-Throughput Spectroscopic Telescope Epsilon Mission, or EUVST, and the Electrojet Zeeman Imaging Explorer, or EZIE, will help us understand the Sun and Earth as an interconnected system.
WASHINGTON (NASA PR) — NASA Administrator Jim Bridenstine will give a keynote address at the virtual fall Lunar Surface Innovation Consortium meeting at 11:45 a.m. EDT Wednesday, Oct. 14. The event, co-hosted by the Johns Hopkins Applied Physics Laboratory (APL) and Arizona State University, will stream live on NASA Television and the agency’s website.

EDWARDS, Calif. — It’s no surprise to most of us that regularly eating fresh produce is a great way to support a healthy diet. Fresh fruits and vegetables benefit astronauts on the International Space Station, too – and soon the Moon and beyond. Scientists are investigating sustainable ways to grow highly nutritious foods in microgravity, to give space explorers a readily available supply of daily greens.
REDMOND, Wash., May 19, 2020 (Aerojet Rocketdyne PR) – The dual chemical and electric propulsion systems for NASA’s Double Asteroid Redirection Test (DART) were recently delivered by Aerojet Rocketdyne to the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
The chemical propulsion system and the electric propulsion Xenon feed system have been undergoing assembly and integration onto the spacecraft structure at Aerojet Rocketdyne’s facility in Redmond, Washington, since August 2019.
New Horizons Mission Update by Alan Stern Principal Investigator
New Horizons is healthy and performing perfectly as it flies deeper and deeper into the Kuiper Belt! Recently we conducted an engineering review of the spacecraft to “trend” how it was working compared to when it was launched. The result was amazing: Every system and science instrument aboard New Horizons is working as well as it did when we lifted off, more than 14 years and almost 5 billion miles ago. As mission principal investigator I could not be prouder — the men and women who designed, built and tested New Horizons literally created a masterpiece of American workmanship that will likely be able to perform and explore for many more years and many more miles!
NASA Associate Administrator Steve Jurcyk said on Friday that the first Artemis mission to the moon will not launch later this year but will hopefully fly in the mid- to late 2021 time frame.
It marks yet another delay in a program that is already running years behind schedule and billions of dollars over budget. The slip potentially makes the Trump Administration’s goal of landing astronauts at the south pole of the moon in 2024 more difficult to achieve.
WASHINGTON (NASA PR) — An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the EuropaClipper mission’s next phase. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science payload.
“We are all excited about the decision that moves the Europa Clipper
mission one key step closer to unlocking the mysteries of this ocean
world,” said Thomas Zurbuchen, associate administrator for the Science
Mission Directorate at NASA Headquarters in Washington. “We are building
upon the scientific insights received from the flagship Galileo and
Cassini spacecraft and working to advance our understanding of our
cosmic origin, and even life elsewhere.”
The mission will conduct an in-depth exploration of Jupiter’s moon,
Europa, and investigate whether the icy moon could harbor conditions
suitable for life, honing our insights into astrobiology. To
develop this mission in the most cost-effective fashion, NASA is
targeting to have the Europa Clipper spacecraft complete and ready for
launch as early as 2023. The agency baseline commitment, however,
supports a launch readiness date by 2025.
NASA’s Jet Propulsion Laboratory in Pasadena, California leads the
development of the Europa Clipper mission in partnership with the Johns
Hopkins University Applied Physics Laboratory for the Science Mission
Directorate. Europa Clipper is managed by the Planetary Missions Program
Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
What color is Pluto? The answer, revealed in the first maps made from New Horizons data, turns out to be shades of reddish brown. Although this is reminiscent of Mars, the cause is almost certainly very different. On Mars the coloring agent is iron oxide, commonly known as rust. On the dwarf planet Pluto, the reddish color is likely caused by hydrocarbon molecules that are formed when cosmic rays and solar ultraviolet light interact with methane in Pluto’s atmosphere and on its surface.
BALTIMORE, Md. (JHU APL PR) — After 18 months in orbit — months longer than typical for spacecraft in their class — the twin ORS Tech 1 and 2 CubeSats recently completed their final trip into Earth’s atmosphere.
The agency is working on two concepts for the mission. The first concept would fully capture a very small asteroid in free space and the other would retrieve a boulder off of a much larger asteroid. Both concepts would redirect an asteroid mass less than 10 meters in size to orbit the moon. Astronauts aboard the Orion spacecraft launched on the Space Launch System (SLS) would rendezvous with the captured asteroid mass in lunar orbit and collect samples for return to Earth.
