WASHINGTON, March 20, 2020 (NASA PR) — To protect the health and safety of the NASA workforce as the nation responds to coronavirus (COVID-19), agency leadership recently completed the first assessment of work underway across all missions, projects, and programs. The goal was to identify tasks that can be done remotely by employees at home, mission-essential work that must be performed on-site, and on-site work that will be paused.
“We are going to take care of our people. That’s our first priority,” said NASA Administrator Jim Bridenstine. “Technology allows us to do a lot of what we need to do remotely, but, where hands-on work is required, it is difficult or impossible to comply with CDC guidelines while processing spaceflight hardware, and where we can’t safely do that we’re going to have to suspend work and focus on the mission critical activities.”
Editor’s Note: NASA continues to develop WFIRST even as the Trump Administration continues to try to kill it. The administration’s FY 2021 budget request cancels the telescope, a proposal Congress rejected last year.
GREENBELT, Md. (NASA PR) — NASA’s Wide Field Infrared Survey Telescope (WFIRST) project has passed a critical programmatic and technical milestone, giving the mission the official green light to begin hardware development and testing.
The WFIRST space telescope will have a viewing area 100 times larger than that of NASA’s Hubble Space Telescope, which will enable it to detect faint infrared signals from across the cosmos while also generating enormous panoramas of the universe, revealing secrets of dark energy, discovering planets outside our solar system (exoplanets), and addressing a host of other astrophysics and planetary science topics.
SAN ANTONIO, January 9, 2020 (SwRI PR) — Less than two years before launch, scientists associated with NASA’s Lucy mission, led by Southwest Research Institute, have discovered an additional small asteroid that will be visited by the Lucy spacecraft. Set to launch in 2021, its 12-year journey of almost 4 billion miles will explore the Trojan asteroids, a population of ancient small bodies that share an orbit with Jupiter.
GREENBELT, Md. (NASA PR) — Its size and surface gravity are much larger than Earth’s, and its radiation environment may be hostile, but a distant planet called K2-18b has captured the interest of scientists all over the world. For the first time, researchers have detected water vapor signatures in the atmosphere of a planet beyond our solar system that resides in the “habitable zone,” the region around a star in which liquid water could potentially pool on the surface of a rocky planet.
BALTIMORE, Md. (NASA PR) — A small asteroid has been caught in the process of spinning so fast it’s throwing off material, according to new data from NASA’s Hubble Space Telescope and other observatories.
Images from Hubble show two narrow, comet-like tails of dusty debris streaming from the asteroid (6478) Gault. Each tail represents an episode in which the asteroid gently shed its material — key evidence that Gault is beginning to come apart.
NASA has regressed in its efforts to control cost growth and schedule delays on its various high-risk projects, according to a new report from the Government Accountability Office (GAO).
“Following several years of continuing a generally positive trend of limiting cost growth and schedule delays for its portfolio of major projects, we found that NASA’s average launch delay increased from 7 to 12 months between May 2017 and May 2018,” the report stated. “Further, the overall development cost growth increased from 15.6 percent to at least 18.8 percent over the same time period.”
NASA has received a $21.5 billion budget for fiscal year 2019, which is $736.86 million above FY 2018 and $1.6 billion above the total requested by the Trump Administration.
The funding, which came more than four months into the fiscal year, was included in an appropriations bill signed by President Donald Trump on Friday. NASA’s budget has been on an upward trajectory over the last few years. In FY 2018, the space agency received an $1.64 billion increase over the previous year.
WASHINGTON (NASA PR) — NASA has moved closer to conducting science operations again with the Hubble Space Telescope’s Wide Field Camera 3 instrument, which suspended operations on Tuesday, Jan. 8. Today, Jan. 15, the instrument was brought back to its operations mode.
Shortly after noon EST on Jan. 8, software installed on the Wide Field Camera 3 detected that some voltage levels within the instrument were out of the predefined range. The instrument autonomously suspended its operations as a safety precaution. Upon further investigation, the voltage levels appeared to be within normal range, yet the engineering data within the telemetry circuits for those voltage levels were not accurate. In addition, all other telemetry within those circuits also contained erroneous values indicating that this was a telemetry issue and not a power supply issue.
After resetting the telemetry circuits and associated boards, additional engineering data were collected and the instrument was brought back to operations. All values were normal. Additional calibration and tests will be run over the next 48 to 72 hours to ensure that the instrument is operating properly. Further investigation using both the new and the previously collected engineering data will be conducted to determine why those data values were originally incorrect.
Assuming that all tests work as planned, it is expected that the Wide Field Camera 3 will start to collect science images again by the end of the week.
The Wide Field Camera 3 was installed during the last servicing mission to Hubble back in 2009. Over 2,000 peer-reviewed published papers have been produced from its data. Hubble itself is in its 29th year of operations, well surpassing its original 15-year lifetime.
Hubble operations, like other satellite operations, are excepted activities as defined in the NASA furlough/shutdown plan. The current partial government shutdown does not affect its flight operations.
LAUREL, Md. (JHUAPL PR) — Years before a team of researchers proposed a mission called New Horizons to explore the dwarf planet Pluto, NASA’s Hubble Space Telescope had already made initial observations of the world at the dim outer fringes of our celestial neighborhood. Over many years, Hubble’s pioneering observations repeatedly accomplished what ground-based telescopes could not — imaging features on Pluto’s surface, finding new Plutonian moons, and tracking down a destination to visit after Pluto — an even tinier, icy object in a vast region of small worlds beyond the orbit of Neptune called the Kuiper Belt.
WASHINGTON (NASA PR) — NASA’s Hubble Space Telescope returned to normal operations late Friday, Oct. 26, and completed its first science observations on Saturday, Oct. 27 at 2:10 AM EDT. The observations were of the distant, star-forming galaxy DSF2237B-1-IR and were taken in infrared wavelengths with the Wide Field Camera 3 instrument. The return to conducting science comes after successfully recovering a backup gyroscope, or gyro, that had replaced a failed gyro three weeks earlier.
WASHINGTON (NASA PR) — NASA took great strides last week to press into service a Hubble Space Telescope backup gyroscope (gyro) that was incorrectly returning extremely high rotation rates. The backup gyro was turned on after the spacecraft entered safe mode due to a failed gyro on Friday, Oct. 5. The rotation rates produced by the backup gyro have since reduced and are now within an expected range. Additional tests will be performed to ensure Hubble can return to science operations with this gyro.
GREENBELT, Md. (NASA PR) — NASA continues to work toward resuming science operations of the Hubble Space Telescope after the spacecraft entered safe mode due to a failed gyroscope (gyro) on Friday, Oct. 5.
WASHINGTON (NASA PR) — NASA is working to resume science operations of the Hubble Space Telescope after the spacecraft entered safe mode on Friday, October 5, shortly after 6:00 p.m. EDT. Hubble’s instruments still are fully operational and are expected to produce excellent science for years to come.
Hubble entered safe mode after one of the three gyroscopes (gyros) actively being used to point and steady the telescope failed. Safe mode puts the telescope into a stable configuration until ground control can correct the issue and return the mission to normal operation.
New exomoon candidate has been observed around a star some 8,000 light-years away from Earth and is believed to be around the size of Neptune
New York, NY, October 3, 2018 (Columbia University PR) – A pair of Columbia University astronomers using NASA’s Hubble Space Telescope and Kepler Space Telescope have assembled compelling evidence for the existence of a moon orbiting a gas-giant planet 8,000 light-years away. (more…)
