A Karachi teacher posted her students’ questions to NASA on Twitter. Scientists replied

  • When Aimun Faisal posted her students’ queries about the solar system online, never did she imagine she would get responses or her post would go viral
  • Speaking about what inspires her teaching style, Faisal credited her mother and three teachers she met at “three important moments” in her life

KARACHI: When Pakistani teacher Aimun Faisal posted her students’ questions to NASA on Twitter on Wednesday, never did she imagine scientists and astronauts would respond -- and her post would go viral.

It all began with a class activity where the fourth grade teacher at Karachi’s Cornerstones School asked her students to write down questions about the solar system. Once students had submitted their questions, the class voted to select the best queries.

On Wednesday, Faisal posted six selected questions and the names and photos of the students who had asked them on Twitter.

“These fourth graders have some questions for you,” said the post, in which NASA astronauts and other scientists were tagged. The tweet went viral.

 

 

To Faisal’s surprise and joy, astronauts and scientists replied.

Astronaut Chris Hadfield said to a student called Rayyan who had asked if he ever felt “scared” his space ship would get lost in space:

“Rayyan - I wasn't scared we'd get lost. We had the Earth nearby, and used the stars to steer. I felt especially comforted when I flew over home. Here's a photo I took of Karachi - can you find your school?”

 

 

To Haniyah, who asked if it was true that it rained diamonds on Jupiter, Emily Calandrelli, an American science communicator and the host of Xploration Outer Space and Emily’s Wonder Lab, wrote:

“Haniyah -It's definitely possible!! The same physics and chemistry that creates diamonds here on Earth (putting Carbon under super high heat/pressure) exists on planets like Jupiter, so some scientists hypothesize that it's raining diamonds there! Wouldn't it be fun to see that?!”

 

 

There were several other replies, which Faisal collected, printed out and put into envelopes that she took to class the next day, Thursday. There was a “stunned silence,” she said, when she told the students scientists had replied to their queries.

Faisal once again took to Twitter to describe her students' responses:

“As I started calling out names for the kids to collect their envelopes, there was a quiet whisper, "we all got separate letters?" And after a lull in momentum when one student Anabiya received her letter she cynically remarked "This is not from NASA, this is ma'am's handwriting. So, I asked little miss Sherlock to open her letter.”

 

 

“Haniya kept staring at her letter with her mouth agape even as I tried to give her a background on who these people were that had written back to her,” Faisal wrote.

 

 

“Shy Muhammad who wanted all the answers but was too hesitant to ask any questions, went around showing his letter which told him he is a star and we will make sure he shines the brightest one day. (We're working on that. Send prayers. I saw him laugh for the first time today.)"

 

 

Speaking about what had inspired her teaching style, Faisal said her mother had worked “very hard” in her early years, using puzzles, crosswords and books to keep her interested in her studies.

Then, she said, she met three teachers at “three important moments in life” - Miss Tampal, a principal at Karachi's Mama Parsi school, Zeenat Farookee, her economics teacher in high school, and Ali Raza, a history instructor at university.

“Thankyou everyone who made this go viral! The kids don't know how this happened but I am sure they would be very grateful to all of you if they did,” Faisal wrote on Twitter on Thursday evening. “This is a wrap on the live coverage of the NASA Saga. May Grade 4 continue to have questions, always!”

The students, who had low expectations about getting responses to their queries, Faisal said, were “currently planning a ‘field trip’ to NASA.”


Pakistan police repel militant attack on Bannu checkpoint, five officers injured

Pakistan police repel militant attack on Bannu checkpoint, five officers injured

  • Police say several attackers killed or wounded in overnight assault in northwest Pakistan
  • Incident comes amid surge in militant attacks Pakistan blames on Afghanistan-based groups

ISLAMABAD: Pakistani police said on Friday they repelled an overnight militant attack on a checkpoint in the northwestern district of Bannu, injuring five officers in an area that has seen a sharp rise in militant violence in recent years.

The attack took place late at night at the Sheikh Landak check post, located within the limits of Huweid police station in Bannu, a district of Khyber Pakhtunkhwa province near the Afghan border. Police said officers responded swiftly, preventing the attackers from overrunning the post.

Militant attacks in Pakistan have surged since 2021, particularly in Khyber Pakhtunkhwa and southwestern Balochistan, with security forces frequently targeted. Islamabad says the violence is largely driven by groups it refers to as Fitna Al-Khawarij, a term Pakistani authorities use for militants they say are linked primarily to the Pakistani Taliban and allied factions operating from across the border in Afghanistan. Pakistan has also accused India of backing militant networks involved in attacks, allegations New Delhi denies.

“Late at night, terrorists of Fitna Al-Khawarij carried out a cowardly attack on Sheikh Landak check post,” police said in a statement, adding that officers “displayed full courage, bravery and a timely response, successfully foiling the attack.” 

Police said effective retaliatory fire caused “heavy human and material losses” to the attackers, with reports of several militants killed or wounded.

Five police personnel sustained minor injuries during the exchange and were immediately shifted to hospital for treatment, where they are receiving medical care, the statement said.

Following the attack, additional police units were deployed to the area and a search operation was launched to locate any remaining attackers.

Pakistan has repeatedly accused Afghanistan’s Taliban-led government of failing to prevent militant groups from using Afghan territory to launch attacks inside Pakistan. Kabul denies the allegation, saying it does not allow its soil to be used against any country. 

The accusations have added to tensions between the two neighbors, who have also seen periodic border clashes over the past year.
