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.

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.

PARIS (ESA PR) — An object from another star system that made a brief appearance in our skies guised as an asteroid turns out to be a tiny interstellar comet.

‘Oumuamua, a name that reflects the Hawaiian meaning for ‘a messenger from afar, arriving first’, was discovered by astronomers working with the Pan-STARRS survey in Hawaii in October last year as the object came close to Earth’s orbit. Follow-up observations by ESA’s Optical Ground Station telescope in Tenerife, Canary Islands, and other telescopes around the world helped determine its trajectory.

PASADENA, Calif. (NASA PR) — Nearly all asteroids are so far away and so small that the astronomical community only knows them as moving points of light. The rare exceptions are asteroids that have been visited by spacecraft, a small number of large asteroids resolved by NASA’s Hubble Space Telescope or large ground-based telescopes, or those that have come close enough for radar imaging.

Managing Editor

Despite a last minute threat of a veto, President Donald Trump signed an $1.3 trillion omnibus spending bill on Friday that boosts NASA spending by about $1.1 billion to $20.7 billion.

So, with the fiscal year nearly half over, let’s take a closer look at NASA’s FY 2018 budget, which the Administration had tried to cut. The table below lays out the numbers from the omnibus bill, the Administration’s request and the FY 2017 budget.

New Horizons’ Next Target Just Got a Lot More Interesting

One artist’s concept of Kuiper Belt object 2014 MU69, the next flyby target for NASA’s New Horizons mission. This binary concept is based on telescope observations made at Patagonia, Argentina on July 17, 2017 when MU69 passed in front of a star. New Horizons theorize that it could be a single body with a large chunk taken out of it, or two bodies that are close together or even touching. (Credits: NASA/JHUAPL/SwRI/Alex Parker)

LAUREL, Md. (NASA PR) — Could the next flyby target for NASA’s New Horizons spacecraft actually be two targets?

New Horizons scientists look to answer that question as they sort through new data gathered on the distant Kuiper Belt object (KBO) 2014 MU69, which the spacecraft will fly past on Jan. 1, 2019. That flyby will be the most distant in the history of space exploration, a billion miles beyond Pluto.

NASA’s Hubble Sees Martian Moon Orbiting the Red Planet

The sharp eye of NASA’s Hubble Space Telescope has captured the tiny moon Phobos during its orbital trek around Mars. Because the moon is so small, it appears star-like in the Hubble pictures.

GREENBELT, Md. (NASA PR) — Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a time-lapse video showing the diminutive moon’s orbital path. The Hubble observations were intended to photograph Mars, and the moon’s cameo appearance was a bonus.

Europa Water Vapor Plumes – More Hubble Evidence

Video Caption: The Hubble Space Telescope has captured even more evidence of water vapor plumes on Jupiter’s icy moon Europa. The probable plumes appear to be repeating in the same location and correspond with a relatively warm region on Europa’s surface observed by the Galileo spacecraft.

NASA Missions Provide New Insights into ‘Ocean Worlds’ in Our Solar System

WASHINGTON (NASA PR) — Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope.

In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn’s moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter’s moon Europa.

“This is the closest we’ve come, so far, to identifying a place with some of the ingredients needed for a habitable environment,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. ”These results demonstrate the interconnected nature of NASA’s science missions that are getting us closer to answering whether we are indeed alone or not.”

Could Dream Chaser Service Hubble Space Telescope?

The Wall Street Journal reports that Sierra Nevada Corporation has put forth a proposal to send a crewed Dream Chaser to service the aging Hubble Space Telescope.

The discussions are still preliminary, no specific plans have been drafted and senior White House aides or administration advisers currently overseeing the National Aeronautics and Space Administration could veto the concept. Decisions about any potentially major NASA initiative await the appointment of a new agency head, according to industry and government officials.

But deliberations about sending a spacecraft to link up with NASA’s pioneering orbiting telescope—comparable to five earlier missions by the now-retired space shuttle fleet stretching back to 1993—illustrate the Trump team’s guiding principles when it comes to space investments. Industry and transition officials agree the focus is on seeking dramatic but relatively inexpensive space projects that can be readily understood by average Americans.

The Hubble repair proposal also has garnered administration officials’ attention because it appears to meet still other important White House criteria, according to these people. The goal is to put a lid on federal expenditures for space by fostering public-private partnerships, while devising projects that can be completed within the president’s current four-year term….

Sierra Nevada is betting that the Trump administration’s enhanced interest in commercial space projects—including transition memos extolling the potential benefits of manned missions orbiting the moon—could revive Hubble’s rejuvenation bid. The company twice presented its proposal to transition officials, according to one person familiar with the details.

Sierra Nevada is currently developing a cargo variant of Dream Chaser to resupply the International Space Station. That vehicle is not scheduled to begin deliveries to the space station until 2019.

It’s not clear how much work, funding or additional testing would be required to upgrade the cargo ship for crew use. Nor is it clear whether a mission to Hubble could be completed in time for Trump’s re-election campaign in 2020.

The company did make substantial progress toward a crew vehicle during NASA’s Commercial Crew Program before Dream Chaser was dropped from the program in 2014.

The two selected commercial crew companies, Boeing and SpaceX, have run into significant technical problems during the final phase of commercial crew development and testing. Both companies are running significantly behind schedule.

NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter’s Moon Europa

This composite image shows suspected plumes of water vapor erupting at the 7 o’clock position off the limb of Jupiter’s moon Europa. The plumes, photographed by NASA’s Hubble’s Space Telescope Imaging Spectrograph, were seen in silhouette as the moon passed in front of Jupiter. Hubble’s ultraviolet sensitivity allowed for the features -- rising over 100 miles (160 kilometers) above Europa’s icy surface -- to be discerned. The water is believed to come from a subsurface ocean on Europa. The Hubble data were taken on January 26, 2014. The image of Europa, superimposed on the Hubble data, is assembled from data from the Galileo and Voyager missions. (Credits: NASA/ESA/W. Sparks (STScI)/USGS Astrogeology Science Center)

WASHINGTON (NASA PR) — Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.
