NASA Telescopes Find New Clues About Mysterious Deep Space Signals

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in green) can influence the flow of electrically charged material from the object, which is a type of neutron star. NASA/JPL-Caltech Using two of the agency’s X-ray telescopes, researchers were able to zoom in on a dead star’s erratic behavior as it released a bright, brief burst of…

Team Assessing SHERLOC Instrument on NASA’s Perseverance Rover

NeRD

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Perseverance puts its robotic arm to work around a rocky outcrop called “Skinner Ridge” in a set of images captured in June and July 2022 by the rover’s Mastcam-Z camera system. SHERLOC is mounted on the end of the arm. NASA/JPL-Caltech/ASU/MSSS Engineers are working to stabilize a dust cover on one of the science instrument’s cameras. Data and imagery from NASA’s Perseverance Mars rover indicate one of two covers that keep dust from accumulating on the optics of…

NASA Puts Next-Gen Exoplanet-Imaging Technology to the Test

NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) JPL scientist Vanessa Bailey stands behind the Nancy Grace Roman Coronagraph , which has been undergoing testing at JPL. About the size of a baby grand piano, the Coronagraph is designed to block starlight and allow scientists to see the faint light from planets outside our solar system. A cutting-edge tool to view planets outside our solar system has passed two key tests ahead of its launch as part of the agency’s Roman Space Telescope by 2027. The Coronagraph…

NASA Collaborating on European-led Gravitational Wave Observatory in Space

NeRD

4 min read NASA Collaborating on European-led Gravitational Wave Observatory in Space The LISA (Laser Interferometer Space Antenna) mission, led by ESA (European Space Agency) with NASA contributions, will detect gravitational waves in space using three spacecraft, separated by more than a million miles, flying in a triangular formation. Lasers fired between the satellites, shown in this artist’s concept, will measure how gravitational waves alter their relative distances. AEI/MM/Exozet The first space-based observatory designed to detect gravitational waves has passed a major review and will proceed to the construction of…

This US-Indian Satellite Will Monitor Earth’s Changing Frozen Regions

NeRD

Satellite imagery shows a portion of East Antarctica on Jan. 9, 2022, before icebergs calved off the Glenzer and Conger glaciers. NISAR will observe nearly all of the planet’s land and ice surfaces twice every 12 days, monitoring Earth’s frozen regions, known as the cryosphere. USGS Much of the Glenzer and Conger glaciers had collapsed by March 23, 2022, spawning numerous icebergs, as shown in this satellite image. NISAR will document such changes around the globe, and its geographic coverage of Antarctica will be the most extensive for a radar…

NASA’s Juno to Get Close Look at Jupiter’s Volcanic Moon Io on Dec. 30

NeRD

This image revealing the north polar region of the Jovian moon Io was taken on October 15 by NASA’s Juno. Three of the mountain peaks visible in the upper part of image, near the day-night dividing line, were observed here for the first time by the spacecraft’s JunoCam. Image data: NASA/JPL-Caltech/SwRI/MSSS, Image processing by Ted Stryk The orbiter has performed 56 flybys of Jupiter and documented close encounters with three of the gas giant’s four largest moons. NASA’s Juno spacecraft will on Saturday, Dec. 30, make the closest flyby of…

NASA’s Deep Space Network Turns 60 and Prepares for the Future

NeRD

The radio antennas of the NASA’s Canberra Deep Space Communications Complex are located near the Australian capital. It’s one of three Deep Space Network complexes around the world that keep the agency in contact with over 40 space missions. The DSN marks its 60th anniversary in December 2023. NASA/JPL-Caltech A single radio antenna dish stands alone at the Deep Space Network’s Canberra complex in this photo from 1969, six years after the DSN was founded. Canberra now consists of three 34-meter (112-foot) antennas and one 70-meter (230-foot) antenna. NASA/JPL-Caltech The…

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb

NeRD

Scientists have been studying the universe with infrared space telescopes for 40 years, including these NASA missions, from left: the Infrared Astronomical Satellite (IRAS), launched in 1983; the Spitzer Space Telescope, launched in 2003; and the James Webb Space Telescope, launched in 2021. NASA/JPL-Caltech The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb Space Telescope – the largest…
