The sky will provide a socially distant entertainment activity for stargazers this week: the annual Eta Aquarid Meteor Shower.
The May meteor shower is bits of ice and space dust left behind from Halley’s Comet that crash into Earth’s atmosphere, creating what we see as shooting stars. The annual shower serves as a reminder of the famed fireball only visible from Earth every 75 years or so. Its last sighting was in 1986, putting its next expected sighting in 2061.
This year’s meteor shower is expected to peak between Monday and Wednesday night, and is best viewed from the Southern Hemisphere, where the night is longer at this time of year.
But Northern Hemisphere viewers will have a chance to see the shower between 3 a.m. and dawn, International Meteor Organization Secretary General Robert Lunsford tells NPR.
“You can see them from anywhere as long as the sky is clear,” Lunsford said. But the shower won’t be as good this year as it was last May, he says, because the moon will be full on Thursday, reducing the visibility of meteors.
Viewers should look due east to see the shooting stars, which will be coming up from the horizon and moving quickly across the night sky from their origin in the constellation Aquarius.
Observers in the Northern Hemisphere can expect to see between five and 10 meteors per hour, depending on weather conditions.The more dry and clear the night, the better chance of seeing the shower. In Australia, stargazers reported up to 37 meteors per hour in good conditions.
The key to a successful shower experience, says Lunsford, is to get comfortable.
“Don’t step outside and stand there and expect to see meteor activity,” he says. Instead, he suggests grabbing a lawn chair and a warm blanket and setting up camp in the darkest area possible. “If you’re comfortable, you’re gonna see a lot more activity.”
And if being awake at 4 a.m. is not feasible, more vibrant showers including the Perseids and the Geminids will come later this year with better sky conditions in August and December.

Astronauts describe ride to space aboard SpaceX Crew Dragon – CBS News
Thethat boosted astronauts Douglas Hurley and Robert Behnken into space provided a slightly rougher ride than expected during the later stages of the climb to orbit, but both said Monday they enjoyed their historic trip and marveled at a sooth-as-silk .
And yes, the Crew Dragon brought a “new car smell” to the lab complex.
“It absolutely did,” said station commander Chris Cassidy, the lone American aboard the station until Hurley and Behnken arrived Sunday. “Then when we got that hatch open, you could tell it was a brand new vehicle, with smiley faces on the other side, smiley face on mine, just as if you had bought a new car, the same kind of reaction.
“Wonderful to see my friends, and wonderful to see a brand new vehicle,” he said.
from pad 39A at the Kennedy Space Center Saturday afternoon, strapped into a Crew Dragon capsule atop a Falcon 9 rocket.
It was the first piloted launch to orbit from U.S. soil in nearly nine years, the first flight of a SpaceX rocket carrying astronauts and the first new crewed spacecraft to fly in space since the first shuttle mission 39 years ago.
Both Hurley and Behnken are space shuttle veterans, familiar with the initially rough ride when the orbiter’s powerful solid-propellant boosters were firing and the transition to a much smoother experience after the boosters were jettisoned and only the ship’s liquid fueled main engines were running.
The Falcon 9 is a two-stage rocket powered by liquid oxygen and kerosene. The first stage, featuring nine Merlin engines, generates 1.7 million pounds of thrust at liftoff. The rocket’s second stage is powered by a single vacuum-rated Merlin engine.
“Shuttle had solid rocket boosters, those burned very rough for the first two-and-a-half minutes,” Hurley said. “The first stage with Falcon 9 … was a much smoother ride.”
He said the shutdown of the first stage engines, the separation of the first and second stages and then the ignition of the upper stage’s single engine was similar to the memorable launch sequence depicted in the movie “Apollo 13.”
“So the first stage engines shut off, and then it took some time between the booster separating and then the Merlin vacuum engine starting,” Hurley said. “At that point, we go from roughly three Gs (three times the normal force of gravity on the ground) to zero Gs for, I don’t know, a half a second probably, and then when that Merlin vacuum engine fires, then we start accelerating again.
“It got a little rougher with the Merlin vacuum engine, and it’ll be interesting to talk to the SpaceX folks to find out why it was a little bit rougher ride on second stage than it was for shuttle on those three main engines.”
The Crew Dragon is designed to rendezvous and dock with the space station autonomously, without any direct input from the crew. But for the first piloted test fight, Hurley took over manual control twice to verify astronauts can fly the ship on their own if necessary.
There were no problems and when the Crew Dragon docked with the station Sunday morning, Hurley and Behnken were unable to detect the impact.
“The thing that really stood out to both of us, and we mentioned it as soon as we docked, is we didn’t feel the docking,” Hurley said. “It was just so smooth.”
Hurley is a former test pilot and Behnken, who holds a doctorate in mechanical engineering from Caltech, is a veteran Air Force flight test engineer. They were selected for the first piloted Crew Dragon flight in part so they could bring those skills to evaluating the spacecraft before it begins operational missions to the space station in the late-summer timeframe.
“We’re there to evaluate how it does the mission and so far, it’s done just absolutely spectacularly,” Hurley said. “It’s a very clean vehicle. … It does everything we need it to do for this mission, so we’re very happy with that part of it.”
Including the operation of the Crew Dragon’s toilet. While he did not provide any details, Hurley said it is “very similar to the one we were used to in the space shuttle, and it worked very well. We had no issues with it.”
NASA managers have not yet decided how long Hurley and Behnken will remain in orbit. The Crew Dragon is certified for up to four months in space, but the crew could be ordered home earlier depending on how the space environment affects the capsule’s solar arrays, the weather in the Atlantic Ocean splashdown zone and other factors.
Not knowing when they might be coming home is “a little bit strange,” Behnken said. “I’m trying to explain it to my son, just six years old, and from his perspective, he’s just excited that we’re going to get a dog when I get home. And so he’s accepting that uncertainty and continuing to send messages to me while I’m on orbit.”
The mission is expected to last at least six weeks and possibly up to four months, far longer than their relatively brief shuttle flights. Staying in touch with their wives, both veteran astronauts, and their two sons is a top priority for both Hurley and Behnken.
“One of the things I was most excited about (after launch) was being able to make a phone call home,” Behnken said. “It’s been a long time since I launched into orbit, and I’ve got a little boy who got a chance to watch me do that for the first time in his life. And I just wanted to understand what his experience was and share that a little bit with him.
“He was able to make the trip back to Houston after watching the docking from down in Florida and was pretty excited about the whole thing. So that was wonderful for me.”
Elon Musk announces Twitter break, but it’s a mystery as to why – Digital Trends
Elon Musk surprised his 35 million Twitter followers on Monday night when he announced he was taking a break from the platform.
The message was short and sweet, and offered no explanation as to why he’d decided to step back from the microblogging site, or when he might be back.
Off Twitter for a while
— Elon Musk (@elonmusk) June 2, 2020
The timing may be seen as interesting by some. The SpaceX and Tesla CEO has, after all, courted controversy in the past with some of his Twitter posts. So it’s possible he’s taken advice — or decided for himself — to steer clear of the site during a particularly turbulent time as protests and social unrest continue in multiple states following the police-custody death of George Floyd in Minneapolis last week.
But Musk isn’t one to shy away from controversy, so other factors could also be at play. The billionaire entrepreneur may simply want some time off following an intense period of activity in recent weeks that included a dispute with the authorities over the reopening of his Tesla manufacturing plant in California following coronavirus-related stay-at-home orders, and also a critical SpaceX mission involving the first-ever astronaut launch using the Crew Dragon spacecraft.
He also recently become a father again, and so may want to spend more time with his new son without thinking about his next Twitter post.
Musk’s penultimate post was a retweet 10 hours earlier of a NASA tweet linked to the recent Crew Dragon trip to the International Space Station.
Besides Monday’s post, his last personal tweet came on May 31 to announce that the Crew Dragon had successfully docked with the space station.
The response to Musk’s five-word tweet was mixed, with some wishing him a nice break, and others saying in no uncertain terms how happy they were about his decision.
We will miss you.
