SpaceX aborts launch of GPS Space Force satellite with two seconds to go – CNET

SpaceX shared this scenic view of the Falcon 9 that will carry Space Force’s GPS satellite into orbit. 


SpaceX

SpaceX aborted a scheduled launch of a US military GPS satellite from Florida on Friday night with just about two seconds left in the countdown. The launch was scheduled for a 15-minute window that opened at 6:43 p.m. PT, with the weather forecast at 70% favorable for liftoff. All appeared to be proceeding smoothly, until two seconds before launch. SpaceX was just starting the engine ignition sequence when it stopped the clock.  

“Standing down from tonight’s launch attempt of GPS III-4,” SpaceX tweeted a few minutes before 7 p.m. PT, though it did not say whether a ground or flight vehicle issue was to blame. The next launch window opens at 6:39 p.m. PT Saturday, SpaceX said. 

SpaceX and the US Space Force are getting along famously. Friday’s attempted launch follows a Space Force Falcon 9 launch in June

Once Elon Musk’s company does launch the GPS satellite, it will attempt to land the Falcon 9’s first stage on a drone ship in the Atlantic Ocean. The spacecraft is scheduled to deploy about 90 minutes after liftoff.

SpaceX hosted a livestream of Friday’s launch, which you can watch below to see how events unfolded. 

The GPS III Space Vehicle (SV) 04 is the fourth in a series of GPS satellites operated by the US Space Force, the newest branch of the military. It’ll join a larger satellite constellation already in orbit.

It’s been a busy week for rocket launches that haven’t actually launched. SpaceX was scheduled to send a new batch of Starlink communications satellites into orbit on a Falcon 9 on Thursday, but that launch was scrubbed and will be rescheduled. United Launch Alliance also intended to send up a Delta IV Heavy rocket on Wednesday with a classified spy satellite, but a technical issue stopped the most recent attempt.

The postponed Starlink launch combined with the Space Force mission made for a nifty photo opportunity. SpaceX shared a view on Twitter earlier this week of the two Falcon 9s on their separate launch pads.

We’ll see if SpaceX can escort the GPS mission into orbit as planned. As we’ve seen this week, delays are common.

The metallic asteroid between Mars and Jupiter is … – AlKhaleej Today

Published

 on


According to a new Planetary Science Journal report published by CBS News, a giant metallic asteroid, valued at around $ 10,000,000,000,000,000,000 – more than the entire earth’s economy – orbits Mars and Jupiter.

The massive asteroid 16 Psyche is the subject of a new study by SwRI scientist Tracy Becker, who observed the object at ultraviolet wavelengths.

Asteroid 16 Psyche, as it is called, is possibly the remainder of a planetary core that never properly formed into an actual planet. While most asteroids are made of stone or ice, the incredibly dense psyche is mostly metal and about 140 miles in diameter, making it the size of Massachusetts.

The new study by the Planetary Science Journal found that psyche may be composed of iron and nickel, which are typically found in the cores of planets.

“We have seen meteorites made mostly of metal, but Psyche may be unique in that it is an asteroid made entirely of iron and nickel,” said lead study author Dr. Tracy Becker in a statement. “The earth has a metal core, a mantle and a crust. It is possible that when a psyche protoplanet was forming, it was hit by another object in our solar system and lost its mantle and crust. ”

NASA plans to launch an unmanned spacecraft called Psyche on a SpaceX Falcon Heavy rocket in 2022 to reach the asteroid and study its composition and history. This is the first time NASA has reached a body made entirely of metal. The spaceship will hit the psyche in January 2026.

Back in 2017, researchers told CBS News that they would not use the asteroid’s $ 10,000 trillion metal mass for business profits.

“What makes Psyche and the other asteroids so interesting is that they are seen as the building blocks of the solar system,” said Becker. “It’s fascinating to understand what really makes a planet and possibly see the inside of a planet.” Once we get to Psyche, we will truly understand whether this is the case, even if it is not what we are expect. Whenever there is a surprise, it is always exciting. ”

Blue moon to light up Halloween sky – Sudbury.com

Published

 on


Not only is it Halloween, but Saturday night also marks two rare lunar events.

We are in for a blue moon and a micromoon.

According to NASA, a blue moon occurs about seven times every 19 years.

The moon will not actually be blue Saturday night, the term refers to the time when a second full moon occurs in one month.

The last full moon was on October 1. 

A micromoon, opposite to a supermoon, is when the moon is at its furthest point from Earth. 

Victor Arora, observatory co-ordinator at the University of Waterloo, said not only will the special moon be visible all night, but Mars will also be easy to spot.

“On this evening you’ll be looking at the confluence of these two or three different cosmic events…it makes it a little bit more meaningful…If you want to see the full moon rise just basically look towards the sun, and turn around so your back is against the sun, and that’s the direction the moon will be rising from.” 

Arora added being outdoors and enjoying a unique event such as a blue moon, is a great pandemic-friendly activity.

“There has been an uptick in interest among people wanting to observe in the evenings. Things like telescope sales have gone through the roof – I’ve heard, and spending time with your close circle and getting out into nature.”

Watch a NASA spacecraft approach and touch down on asteroid Bennu – Mashable

Touchdown.

Earlier in October, NASA successfully collected rocky samples from asteroid Bennu, a relatively small, well-preserved space rock some 200 million miles from Earth. On Friday, NASA released footage of the spacecraft, OSIRIS-REx, approaching and briefly touching down on the rubbly Bennu. The events, seen in the space agency’s tweet below, show OSIRIS-REx carefully descending to Bennu’s rock-strewn surface.

The spacecraft collected some 60 grams, or about two ounces, of fine-grained material during the quicktouchdown, which lasted under 16 seconds. To planetary scientists, this asteroidal stuff is invaluable: Bennu hasn’t changed much since the formation of our solar system (4.5 billion years ago), so the samples provide a glimpse into our past, and how our planets formed.

“They are like time capsules from the beginning of our solar system,” Richard Binzel, an astronomer at the Massachusetts Institute of Technology and a scientist working on the OSIRIS-REx mission, told Mashable. “This is like sampling the original ingredients for making planets.”

(The first ambitious mission to carry asteroid samples back to Earth, Japan’s Hayabusa mission, returned in 2010.)

NASA called the endeavor a “Touch-And-Go (TAG) sample collection event.” The maneuver was indeed a quick “tag” of Bennu’s surface. OSIRIS-REx carefully approached the asteroid for over four hours before briefly touching down and firing nitrogen gas to stir up fragments into Bennu’s sample collector. Then, the spacecraft promptly blasted away. 

OSIRIS-REx captured so much surface material that some of the fine grains even escaped before the collector was stowed away for the return trip home. The spacecraft is expected to arrive on Earth with the invaluable cargo on Sep. 24, 2023.
