NASA's Voyager 2 probe nearing interstellar space

Agencies
October 7, 2018

NASA's Voyager 2 probe is approaching interstellar space and has detected an increase in cosmic rays that originate outside our solar system, the US space agency said.

Launched in 1977, Voyager 2 is a little less than 17.7 billion kilometres from Earth, or more than 118 times the distance from Earth to the Sun. Since 2007 the probe has been travelling through the outermost layer of the heliosphere -- the vast bubble around the Sun and the planets dominated by solar material and magnetic fields.

Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause. Once Voyager 2 exits the heliosphere, it will become the second human-made object, after Voyager 1, to enter interstellar space.

Since late August, the Cosmic Ray Subsystem instrument on Voyager 2 has measured about a five per cent increase in the rate of cosmic rays hitting the spacecraft compared to early August.

The probe's Low-Energy Charged Particle instrument has detected a similar increase in higher-energy cosmic rays. Cosmic rays are fast-moving particles that originate outside the solar system. Some of these cosmic rays are blocked by the heliosphere, so mission planners expect that Voyager 2 will measure an increase in the rate of cosmic rays as it approaches and crosses the boundary of the heliosphere.

In May 2012, Voyager 1 experienced an increase in the rate of cosmic rays similar to what Voyager 2 is now detecting. That was about three months before Voyager 1 crossed the heliopause and entered interstellar space. However, Voyager team members note that the increase in cosmic rays is not a definitive sign that the probe is about to cross the heliopause.

Voyager 2 is in a different location in the heliosheath -- the outer region of the heliosphere -- than Voyager 1 had been, and possible differences in these locations mean Voyager 2 may experience a different exit timeline than Voyager 1.

The fact that Voyager 2 may be approaching the heliopause six years after Voyager 1 is also relevant because the heliopause moves inward and outward during the Sun's 11-year activity cycle.

Solar activity refers to emissions from the Sun, including solar flares and eruptions of material called coronal mass ejections. During the 11-year solar cycle, the Sun reaches both a maximum and a minimum level of activity.

"We're seeing a change in the environment around Voyager 2, there's no doubt about that," said Ed Stone, Voyager Project Scientist.

"We're going to learn a lot in the coming months, but we still don't know when we'll reach the heliopause. We're not there yet -- that is one thing I can say with confidence," said Stone.

Patna, Feb 21: The country is paying the price for failure to send Muslims to Pakistan and bring Hindus to India after the Islamic state came into being at the time of Independence, Union minister Giriraj Singh has said, triggering a fresh controversy.

The BJP leader made the remark in Purnea district in the Seemanchal region of Bihar which has a sizeable Muslim population and where the Begusarai MP was canvassing in favor of the Citizenship (Amendment) Act.

Highlighting the need for such a legislation, he told reporters late Thursday "when our forefathers were fighting for Independence from British rule, Jinnah was pushing for the creation of an Islamic state".

"Our forefathers, however, committed a mistake. Had they ensured that all our Muslim brothers were sent to Pakistan and Hindus brought here, the need for such a move (CAA) would not have arisen. This did not happen and we have paid a heavy price for it," the outspoken BJP leader said.

The CAA, which seeks to fast-track granting citizenship to non-Muslim refugees from Pakistan, Bangladesh and Afghanistan who might have fled their home countries because of religious persecution, has become a major bone of contention since it is feared that a country-wide National Register for Citizens (NRC) may follow.

The Narendra Modi government, which had formerly hinted that a country-wide NRC was on the anvil, seems to have put it on the backburner though a section of citizens across the country, especially Muslims, have been organizing protests out of fear that, if implemented, the NRC may result in a large number of people becoming stateless.

Singh has often been in the crosshairs of the opposition for placing his foot in the mouth. This time, however, his words were frowned upon even by NDA ally Lok Janshakti Party, founded by his cabinet colleague Ram Vilas Paswan and now headed by his son Chirag Paswan.

The young LJP chief, who kicked off a state-wide "Bihar First-Bihari First" yatra here Friday morning, to project the NDAs progressive face ahead of the assembly polls due later this year, expressed strong disapproval of Singh's utterance and noted the coalition had to suffer in the Delhi polls because of "divisive" remarks by BJP leaders.

"We are an NDA constituent but many times our coalition partners say things which the LJP does not at all agree with. This one (Giriraj Singhs statement) is such an example. Had a person of my party spoken in this fashion, I would have taken responsibility and acted," Paswan said.

He said he had placed his view repeatedly on record that the coalition had to suffer on account of divisive remarks, Paswan said in apparent reference to inflammatory speeches by BJP leaders like Union minister Anurag Thakur and BJP MP Parvesh Verma, among others.

"The people of Delhi voted on the basis of performance. We wish they do so again in Bihar and real issues don't get drowned in political cacophony.

"The Nitish Kumar government has accomplished a lot, though much more needs to be achieved. We wish to reach out to people with our vision for the future, said Paswan, before he embarked on the yatra on a customized bus decorated like a chariot in front of which he offered prayers and smashed a coconut.

Meanwhile, Giriraj Singh who loves to wear his Hindu nationalism on the sleeves was busy joining issue with Asaduddin Owaisi's AIMIM which has been under attack for controversial remarks by its leader Waris Pathan.

Sharing video of an old speech by Owaisis brother Akbaruddin which had landed him in jail, besides Pathan's recent remark, Singh asked the opposition RJD-Congress combine in Bihar and the "tukde tukde gang" whether they wanted to "convert India into Pakistan".

New Delhi, Jan 3: US aviation regulator Federal Aviation Administration on Thursday warned America's airlines and their pilots that there is risk involved in operating flights in Pakistan airspace due to "extremist or militant activity", according to an official document.

"Exercise caution during flight operations. There is a risk to US civil aviation operating in the territory and airspace of Pakistan due to extremist/militant activity," said the US Federal Aviation Administration (FAA) in a notice to airmen (NOTAM) dated December 30, 2019.

The NOTAM is applicable to all US-based airlines and US-based pilots.

The US regulator said in its NOTAM that there continues to be a risk to US civil aviation sector from attacks against airports and aircraft in Pakistan, particularly for aircraft on the ground and aircraft operating at low altitudes, including during the arrival and departure phases of flights.

"The ongoing presence of extremist/militant elements operating in Pakistan poses a continued risk to US civil aviation from small-arms fire, complex attacks against airports, indirect weapons fire, and anti-aircraft fire, any of which could occur with little or no warning," it said.

The FAA said that while, to date, there have been no reports of man-portable air defense systems or Manpads being used against the civil aviation sector in Pakistan, some extremist or terrorist groups operating there are suspected of having access to these Manpads.

"As a result, there is potential risk for extremists/militants to target civil aviation in Pakistan with Manpads," it said.

The regulator added that pilots or airlines must report safety or security incidents - which may happen in Pakistan - to the FAA.

Pakistan on July 16 last year opened its airspace for India after about five months of restrictions imposed in the wake of a standoff with New Delhi.

Following the Balakot airstrikes by the Indian Air Force, Pakistan had closed its airspace on February 26 last year.

Pakistan in October last year had denied India's request to allow Prime Minister Narendra Modi's VVIP flight to use its airspace for his visit to Saudi Arabia over the Jammu and Kashmir issue.
