NASA chief urges space agency employees to work from home amid coronavirus outbreak – Space.com

Published

 on


NASA chief Jim Bridenstine has urged all space agency employees who can work from home to do so due to the ongoing coronavirus outbreak, with workers at three space centers testing positive for COVID-19, the disease caused by the virus.

Last week, an employee at NASA’s Ames Research Center in California’s Silicon Valley tested positive for COVID-19, prompting the agency to issue mandatory work-from-home orders for the center. Since then, an employee at the agency’s Marshall Space Flight Center in Alabama has also tested positive, sending that center into a mandatory telework status as well. Both centers are in what NASA calls a Stage 3 response to the coronavirus outbreak, Bridenstine said in a statement Saturday (March 14).

“While we do not have any confirmed cases of COVID-19 at any other NASA center as of today, March 14, out of an abundance of caution, all other NASA centers are transitioning to Stage 2 of our response framework,” he added. “In Stage 2, telework is strongly encouraged for employees who can work remotely. I’ve directed employees to take home their laptop computer, power cord, NASA badge and any other equipment needed to work effectively from an alternate location, as well as essential personal items they may need.”

Coronavirus basics

NASA employees must stay in contact with their supervisors and avoid all travel that is not mission-essential, Bridenstine said. 

He urged even mission-essential personnel to stay home if they aren’t feeling well.

“As I’ve told the NASA community, if you are performing mission-essential work on center, do not go to work if you feel sick. Everyone should take extra precautions to protect themselves and others,” he said (emphasis is NASA’s). “I’ve asked employees to please continue to follow guidance from the Centers for Disease Control and Prevention and the agency’s chief health and medical officer, and if they have questions, don’t hesitate to talk with their supervisor.”

Bridenstine said NASA’s response to the coronavirus to date has safeguarded the space agency against the worst effects of the outbreak.

“The vigilance our workforce has displayed in our response to coronavirus is remarkable and has placed our agency in a position of strength as we confront this national emergency,” he said. “I’m grateful for all the members of the NASA community and everything they’re doing to care for the health of our workforce and keeping the mission going. We will get through this together, and NASA will continue to accomplish amazing things for our country and all of humanity.”

SpaceX sends 23 Starlink satellites into low-Earth orbit

Published

 on

April 23 (UPI) — SpaceX launched 23 Starlink satellites into low-Earth orbit Tuesday evening from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Liftoff occurred at 6:17 EDT with a SpaceX Falcon 9 rocket sending the payload of 23 Starlink satellites into orbit.

The Falcon 9 rocket’s first-stage booster landed on an autonomous drone ship in the Atlantic Ocean after separating from the rocket’s second stage and its payload.

The entire mission was scheduled to take about an hour and 5 minutes to complete from launch to satellite deployment.

The mission was the ninth flight for the first-stage booster that previously completed five Starlink satellite-deployment missions and three other missions.

NASA Celebrates As 1977’s Voyager 1 Phones Home At Last

Published

 on

Voyager 1 has finally returned usable data to NASA from outside the solar system after five months offline.

Launched in 1977 and now in its 46th year, the probe has been suffering from communication issues since November 14. The same thing also happened in 2022. However, this week, NASA said that engineers were finally able to get usable data about the health and status of its onboard engineering systems.

Slow Work

Fixing Voyager 1 has been slow work. It’s currently over 15 billion miles (24 billion kilometers) from Earth, which means a radio message takes about 22.5 hours to reach it—and the same again to receive an answer.

The problem appears to have been its flight data subsystem, one of one of the spacecraft’s three onboard computers. Its job is to package the science and engineering data before it’s sent to Earth. Since the computer chip that stores its memory and some of its code is broken, engineers had to re-insert that code into a new location.

Next up for engineers at NASA’s Jet Propulsion Laboratory in California is to adjust other parts of the FDS software so Voyager 1 can return to sending science data.

Beyond The ‘Heliopause’

The longest-running and most distant spacecraft in history, Voyager 1, was launched on September 5, 1977, while its twin spacecraft, Voyager 2, was launched a little earlier on August 20, 1977. Voyager 2—now 12 billion miles away and traveling more slowly—continues to operate normally.

Both are now beyond what astronomers call the heliopause—a protective bubble of particles and magnetic fields created by the sun, which is thought to represent the sun’s farthest influence. Voyager 1 got to the heliopause in 2012 and Voyager 2 in 2018.

Pale Blue Dot

Since their launch from Cape Canaveral, Florida, aboard Titan-Centaur rockets, Voyager 1 and Voyager 2 have had glittering careers. Both photographed Jupiter and Saturn in 1979 and 1980 before going their separate ways. Voyager 1 could have visited Pluto, but that was sacrificed so scientists could get images of Saturn’s moon, Titan, a maneuver that made it impossible for it to reach any other body in the solar system. Meanwhile, Voyager 2 took slingshots around the planets to also image Uranus in 1986 and Neptune in 1989—the only spacecraft ever to image the two outer planets.

On February 14, 1990, when 3.7 billion miles from Earth, Voyager 1 turned its cameras back towards the sun and took an image that included our planet as “a mote of dust suspended in a sunbeam.” Known as the “Pale Blue Dot,” it’s one of the most famous photos ever taken. It was remastered in 2019.

NASA hears from Voyager 1, the most distant spacecraft from Earth, after months of quiet

Published

 on

 

CAPE CANAVERAL, Fla. (AP) – NASA has finally heard back from Voyager 1 again in a way that makes sense.

The most distant spacecraft from Earth stopped sending back understandable data last November. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble.

NASA’s Jet Propulsion Laboratory in Southern California declared success after receiving good engineering updates late last week. The team is still working to restore transmission of the science data.

It takes 22 1/2 hours to send a signal to Voyager 1, more than 15 billion miles (24 billion kilometers) away in interstellar space. The signal travel time is double that for a round trip.

Contact was never lost, rather it was like making a phone call where you can’t hear the person on the other end, a JPL spokeswoman said Tuesday.

Launched in 1977 to study Jupiter and Saturn, Voyager 1 has been exploring interstellar space – the space between star systems – since 2012. Its twin, Voyager 2, is 12.6 billion miles (20 billion kilometers) away and still working fine.
