After months of radio silence, NASA has finally reconnected with its Voyager 2 space craft. The Voyager 2 spacecraft has been scouring the cosmos for longer than 40 years, all that time staying in contact with NASA’s team of engineers. However, in March of this year, NASA closed communication with the craft.

The space agency left the shuttle to spend a secluded few months in space without signal to upgrade its communication system. Flying some 11.5 billion miles away from Earth, Voyager 2 was left to its own equipment in mid-March.

But on October 29th right before Halloween, NASA briefly reconnected with Voyager 2 while testing its new Deep Space Network antennas (DSN), NASA reported. Voyager 2 was on an important scientific mission originally to study the outer planets, and now in its extended mission, to study deep Interstellar Space in general.

It’s also one of the furthest manmade objects from Earth. NASA notes that Voyager 2 has left the Solar System entirely. To communicate with the spacecraft, NASA relies on the Deep Space Network antennas (DSN).

The DSN is reliable. But much like the Voyager 2, it’s old, very old. To be more precise, it’s more than 70 years old. To put that into perspective, the system was first created when NASA launched its first satellite, Explorer 1, in 1958. The DSN is used to communicate with an estimated 30 spacecraft every day and it runs 24 hours a day, 365 days a year. As another fun fact, the system is spread out across three joint sites located in the United States, Australia, and Spain.

As NASA prepares for numerous new missions to the moon and mars, all launching in the next few years, the DSN is certainly overdue for a much-needed upgrade to its systems and software.

NASA also started its critical work with an antenna denominated Dss43 that is 230-feet-wide, about the size of a 20-story building, and is located in Canberra, Australia. Dss43 has been operational for 48 years and some of its components, including the conductor used to actively communicate with Voyager 2, have never been given a tune-up. NASA has now drastically improved Dss43’s heating and cooling equipment, power supply equipment, and other devices used to operate. On October 29th, NASA sent a brief call to Voyager 2 to test the new equipment to make sure it was operational.

“What makes this task unique is that we’re doing work at all levels of the antenna, from the pedestal at ground level all the way up to the feedcones at the center of the dish that extend above the rim,” Brad Arnold, the DSN project manager at NASA’s Jet Propulsion Lab in Southern California, said in a statement. “This test communication with Voyager 2 definitely tells us that things are on track with the work we’re doing.”

In the test, NASA’s mission control operators on the ground transmitted a series of commands to Voyager 2, and the spacecraft executed the commands, confirming the test was a success.

NASA is going to cut off its communications to Voyager 2 again until later next year. Dss43 will not be fully back online until February 202, so Voyager 2 will have to endure several more months without communication to ground control, which is worrying for engineers.

“Having the antenna down for one year is not an ideal situation for Voyager or for many other NASA missions,” Philip Baldwin, operations manager for NASA’s Space Communications and Navigation (SCaN) Program, said in a statement. “The agency made the decision to conduct these upgrades to ensure that the antenna can continue to be used for current and future missions. For an antenna that is almost 50 years old, it’s better to be proactive than reactive with critical maintenance.”

Thankfully, Voyager 2 doesn’t have humans on board and its just a space probe, otherwise, things could get really serious if communication had to be cut off.

Police Rescue Dogs Trapped In Car on Sizzling Hot Day, Owners Complain About Broken Window

Police in the UK acted quickly to save a two dogs locked inside a car in sizzling hot temperatures by smashing open a window, upsetting the car’s owner over the damage.

Officers responded Sunday to reports that a beagle and another dog were trapped in a car parked in the seaside British city of Brighton on a day of boiling heat.

In video captured of the incident, an officer can be seen jamming his baton through a rear window before finally shattering it to free the pooches.

This prompts the car alarm to go off as the car’s owners can be seen rushing toward it, upset over the police intervention.

A woman, standing with her shocked family, says: “You broke my window out!”

One of the officer responded: “It’s a hot day. You shouldn’t be leaving the dog in the car in this weather.”

The incident happened on a day when people across the region flock to the seaside resort city to dip into the beaches amid surging hot temperatures.

The onlooker who filmed the incident noted that the owners seemed unaware of the dangers posed to their pets by weather conditions.

“Where they had parked there is just no shade,” they told The Sun. “It’s directly on the seafront in 25°C (77°F) weather outside – I’ve got no idea what it was inside the car.”

The family was indignant over what they claim was an overreaction by the police.

“At first it was ‘what the f*** are you doing, why did you break my car window? I was only gone for 10 minutes,’” another witness explained.

“The bloke obviously thought he was completely in the right,” they added. “He didn’t really seem to have much empathy.”

According to UK animal welfare group RSPCA, outside temperatures of 22°C (71°F) can reach a brutal 47°C (116.6°F) inside a car within an hour.

“Police officers attended and tried to get a contact number for the owners of the car but were unable,” a Sussex Police spokesperson said. “Officers had no choice but to smash the side window to gain access and a kind member of the public donated a bottle of water.”

Authorities added that the officers let the pet owners off with a stern warning, without ticketing the family or separating their dogs from them.

Scientists Prove What Causes Aurora Borealis for the First Time

Since the dawn of time, humans have been mystified by what causes the aurora borealis or northern lights. However, a group of scientists have finally uncovered what causes the dazzling lightshow that has captivated people for so long.

Researchers at the University of Iowa have proven that the shimmering auroras are the result of powerful electromagnetic waves during geomagnetic storms, according to a newly published study.

According to the study, phenomena known as Alfven waves propel electrons toward Earth and cause the particles to produce the brilliant display of northern lights seen in the higher latitudes of our planet,

“Measurements revealed this small population of electrons undergoes ‘resonant acceleration’ by the Alfven wave’s electric field, similar to a surfer catching a wave and being continually accelerated as the surfer moves along with the wave,” Prof. Greg Howes, a co-author of the study, told CNN.

Scientists have long understood that the aurora was the likely result of electrons surfing across the electric field, at least since the theory was introduced in 1946 by Soviet scientist Lev Landau.

However, the University of Iowa professors were able to finally put the theory to the test through a simulation at a lab at the Large Plasma Device (LPD) in the Basic Plasma Science Facility of the University of California, Los Angeles (UCLA).

Using a 20-meter-long chamber to simulate the magnetic field of the Earth through state-of-the-art magnetic field coils, scientists were able to generate plasma similar to that which exists in spac.

“Using a specially designed antenna, we launched Alfven waves down the machine, much like shaking a garden hose up and down quickly, and watching the wave travel along the hose,” said Howes.

While this didn’t result in the type of auroras we might see in the sky, “our measurements in the laboratory clearly agreed with predictions from computer simulations and mathematical calculations, proving that electrons surfing on Alfven waves can accelerate the electrons (up to speeds of 45 million mph) that cause the aurora,” Howes noted.

Scientists across the country were elated by the results of the experiment.

“I was tremendously excited! It is a very rare thing to see a laboratory experiment that validates a theory or model concerning the space environment,” said Patrick Koehn, a scientist in the Heliophysics Division of NASA.

“Space is simply too big to easily simulate in the lab,” he added.

Researchers are hopeful that a greater understanding will allow forecasters to better understand weather conditions in space.

Arizona Restores Gas Chamber Where ‘Nazi-Era’ Gas Will be Used for Executions

Arizona has restored an old gas chamber retired during the 20th century in a bid to continue executing its inmates on death row, renewing criticisms about capital punishment and a method of execution the United States once rejected for being excessively cruel and unusual.

The gas chamber, which hasn’t been operated since it executed its last inmate 1999, has been refurbished to ensure that it can properly function as an option for death row prisoners to choose, reports Associated Press.

The move comes after the Grand Canyon State made a large purchase of ingredients to manufacture its own hydrogen cyanide gas.

The same chemicals Arizona plans on using were also used by the Nazis during the holocaust under the brand name Zyklon B. News articles about Arizona’s plans have provoked outrage among survivors of Nazi death camps in Germany and Israel.

“Whether or not one supports the death penalty as a general matter, there is general agreement in American society that a gas devised as a pesticide, and used to eliminate Jews, has no place in the administration of criminal justice,” wrote the American Jewish Committee said in a statement. 

The federal government has also used the gas in past executions of prisoners.

Arizona’s revival of the old execution method comes as prison authorities across the country continue to grapple with problems over another form of execution decried by critics as brutal, namely the use of lethal injection.

Once depicted as a more humane and painless form of killing prisoners, lethal injection has often led to slow, torturous and excruciating deaths. Additionally, many of the chemicals used in lethal injection drugs are impossible to attain due to the refusal of drug makers to continue manufacturing them – effectively cutting off the “choices” given to death row inmates about their preferred method of death.

In South Carolina, a recently-passed law would see inmates being forced to choose between firing squad and an electric chair, reports NPR.

In the waning days of the Trump administration, the outgoing president also vigorously pushed to fast-track the use of death by firing squad and death by electrocution.

At the time, former federal prosecutor Miriam Krinsky, who also heads the Fair and Just Prosecution advocacy group, said:

“As we find itself in the midst of a national reckoning with racism and our history of racial violence, ending the death penalty must be part of our transformation … Abolishing the death penalty would be a signal that the Biden-Harris administration is committed to fairness, equity, and evidence-based justice — and the time for this definitive move is long overdue.”
