SpaceX satellites falling out of orbit after solar storm – Arab News

Published

 on


CAPE CANAVERAL: SpaceX’s newest fleet of satellites is tumbling out of orbit after being struck by a solar storm.
Up to 40 of the 49 small satellites launched last week have either reentered the atmosphere and burned up, or are on the verge of doing so, the company said in an online update Tuesday night.
SpaceX said a geomagnetic storm last Friday made the atmosphere denser, which increased the drag on the Starlink satellites, effectively dooming them.
Ground controllers tried to save the compact, flat-panel satellites by putting them into a type of hibernation and flying them in a way to minimize drag. But the atmospheric pull was too great, and the satellites failed to awaken and climb to a higher, more stable orbit, according to the company.
SpaceX still has close to 2,000 Starlink satellites orbiting Earth and providing Internet service to remote corners of the world. They circle the globe more than 340 miles up (550 kilometers).
The satellites hit by the solar storm were in a temporary position. SpaceX deliberately launches them into this unusually low orbit so that any duds can quickly reenter the atmosphere and pose no threat to other spacecraft.
There is no danger from these newly falling satellites, either in orbit or on the ground, according to the company.
Each satellite weighs less than 575 pounds (260 kilograms).
SpaceX described the lost satellites as a “unique situation.” Such geomagnetic storms are caused by intense solar activity like flares, which can send streams of plasma from the sun’s corona hurtling out into space and toward Earth.
Since launching the first Starlink satellites in 2019, Elon Musk envisions a constellation of thousands more satellites to increase Internet service. SpaceX is trying to help restore Internet service to Tonga through this network following the devastating volcanic eruption and tsunami.
London-based OneWeb has its own Internet satellites up there. And Amazon plans to start launching its satellites later this year.
Astronomers are distressed that these mega constellations will ruin nighttime observations from Earth. The International Astronomical Union is forming a new center for the protection of dark skies.

Dusty demise for NASA Mars lander in July; power dwindling – CGTN

Published

 on


A NASA spacecraft on Mars is headed for a dusty demise. 

The InSight lander is losing power because of all the dust on its solar panels. NASA said Tuesday it will keep using the spacecraft’s seismometer to register marsquakes until the power peters out, likely in July. Then flight controllers will monitor InSight until the end of this year, before calling everything off. 

“There really hasn’t been too much doom and gloom on the team. We’re really still focused on operating the spacecraft,” said Jet Propulsion Laboratory’s Bruce Banerdt, the principal scientist. 

Since landing on Mars in 2018, InSight has detected more than 1,300 marsquakes; the biggest one, a magnitude 5, occurred two weeks ago. 

It will be NASA’s second Mars lander lost to dust: A global dust storm took out Opportunity in 2018. In InSight’s case, it’s been a gradual gathering of dust, especially over the past year.

NASA’s two other functioning spacecraft on the Martian surface – rovers Curiosity and Perseverance – are still going strong thanks to nuclear power. The space agency may rethink solar power in the future for Mars, said planetary science director Lori Glaze, or at least experiment with new panel-clearing tech or aim for the less-stormy seasons.

InSight currently is generating one-tenth of the power from the sun that it did upon arrival. Deputy project manager Kathya Zamora Garcia said the lander initially had enough power to run an electric oven for one hour and 40 minutes; now it’s down to 10 minutes max. 

The InSight team had anticipated this much dust buildup, but hoped a gust of wind or dust devil might clean off the solar panels. That has yet to happen, despite several thousand whirlwinds coming close. 

“None of them have quite hit us dead-on yet enough to blow the dust off the panels,” Banerdt told reporters. 

Another science instrument, dubbed the mole, was supposed to burrow 16 feet (5 meters) underground to measure the internal temperature of Mars. But the German digger never got deeper than a couple of feet (a half-meter) because of the unexpected composition of the red dirt, and it finally was declared dead at the beginning of last year.

Blood moon, big city: Skywatcher captures total lunar eclipse over New York (photos) – Space.com

Published

 on


The eclipsed moon burns red high above the bright lights of New York City in gorgeous photos captured by amateur astronomer Alexander Krivenyshev.

Krivenyshev, the president of WorldTimeZone.com, snapped images of the total lunar eclipse on Sunday night (May 15) from Guttenberg, New Jersey, which is across the Hudson River from the Big Apple. 

He persevered through cloudy conditions, Krivenyshev told Space.com via email, to get shots of the blood-red moon shining like a beacon in a light-polluted sky.

The eclipse began at 9:32 p.m EDT on Sunday (0132 GMT on May 16) when the moon nosed into the light part of Earth’s shadow, known as the penumbra, and ended five hours later. The total eclipse phase, in which the moon was completely darkened by Earth’s heavier umbral shadow, lasted 85 minutes, the longest of any lunar eclipse in 33 years.

Earth’s nearest neighbor temporarily turns a coppery red during total lunar eclipses. This “blood moon” effect is caused by Earth’s atmosphere, which bends some red light onto the lunar surface while scattering away shorter-wavelength light. (No sunlight is hitting the moon directly at this point, of course; Earth is blocking the sun from the moon’s perspective.)

Last weekend’s sky show was best observed from the Americas and parts of Western Europe and West Africa. It was the first total lunar eclipse of the year, but it won’t be the last; another one will occur on Nov. 8. The Nov. 8 lunar eclipse will be best observed from Australia, eastern Asia and the western United States.
