US shutdown delays space missions but NASA not grounded: Report,

NASA’s Focusing Optics X-ray Solar Imager, or FOXSI — a sounding rocket mission — is soon set to stare directly at the Sun and search for nanoflares — miniature explosions invisible to the naked eye — using its X-ray vision, the US space agency said.

The FOXSI mission will take its third flight from the White Sands Missile Range in White Sands, New Mexico, no earlier than September 7, the agency said in a statement.


Derived from the nautical term “to sound”, meaning to measure, FOXSI rockets make brief 15-minute journeys above the Earth’s atmosphere for a peek at space before falling back to the ground.

FOXSI will travel 190 miles up, above the shield of Earth’s atmosphere, to view the sun.

“FOXSI is the first instrument built specially to image high-energy X-rays from the Sun by directly focusing them,” said Lindsay Glesener, space physicist at the University of Minnesota in Minneapolis and principal investigator for the mission.

“Other instruments have done this for other astronomical objects but FOXSI is so far the only instrument to optimise especially for the Sun,” Glesener added.

Nanoflares — small but intense eruptions — are born when magnetic field lines in the Sun’s atmosphere tangle up and stretch until they break like a rubber band. The energy they release accelerates particles to near light speed and according to some scientists, heats the solar atmosphere to its searing million-degree Fahrenheit temperature.

All of this happens in colours of light so extreme that the human eye cannot see them, the scientists explained.

To focus the X-rays, the FOXSI team used extremely hard, smooth surfaces tilted to a small angle (less than half a degree) that would gently corral incoming X-ray light to a point of focus.

The third mission also includes a new telescope designed for imaging lower-energy, so-called soft X-rays as well.

“Including the soft X-ray telescope gives us more precise temperatures” allowing the team to spot nanoflare signatures that would be missed with the hard X-ray telescopes alone, said Glesener.

In addition, several other performance improvements have been made to produce more accurate, higher resolution images.

FOXSI rockets are smaller, cheaper and faster to develop than large-scale satellite missions, sounding rockets which offer a way for scientists to test their latest ideas and instruments and achieve rapid results.

The first FOXSI flight was in 2012, during which it successfully viewed a small solar flare in progress, and its second in 2014, when it detected the best evidence at the time of X-ray emission from nanoflares. (IANS)

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body

Actress Kangana Ranaut has talked about how her weight adjustments for her latest 'Thalaivii' that "messed up many things" in her body and left her with "permanent stretch marks". For her role in the film, based on the life of late Tamil Nadu Chief Minister and former actress J. Jayalalithaa, Kangana had to gain 20kg and undergo major physical transformation several times.

She took to Instagram to share her experience, detailing that doing all that over the six months period left her with "permanent stretch marks". "Gaining 20 kgs in 6 months and loosing it all within 6 months that too in my thirties messed up many things in my bodya I also have permanent stretch marks as well but art comes to life with a price and more often than not price is the artist him/herself," she wrote.

"Thalaivii" showcases the varied aspects of Jayalalithaa's life, tracing her journey as an actress at a young age to becoming the face of Tamil cinema, as well as the rise of the revolutionary leader who changed the course of the state's politics. Talking about her upcoming works, Kangana currently has 'Dhaakad'.

She is also shooting for her next 'Tejas', where she plays a fighter pilot. The Indian Air Force was the first of the country's defence forces to induct women into combat roles in 2016. The film takes inspiration from the landmark event. 'Tejas' is directed by debutant Sarvesh Mewara. The film will be RSVP's second film which pays a tribute to the Indian military after the immensely successful film "Uri: The Surgical Strike" which was released in January 2019. (IANS/ MBI)

Signal's encrypted messaging app continues to be down on Monday after facing global outage on Sunday.

Signal's encrypted messaging app continues to be down on Monday after facing global outage on Sunday. The firm said it is working to fix it. "Hold tight, folks! Signal is currently down, due to a hosting outage affecting parts of our service. We're working on bringing it back up," the firm said in a tweet on Sunday.

The status website says the encrypted messaging app is "experiencing technical difficulties" and many people are also getting an in-app error message that says the same thing. Signal allows for secure and encrypted video, voice and text communication, but users are unable to send any messages.

According to Downdetector.com, users started reporting outages around 11:05 PM Eastern Standard Time and it appears to be affecting people around the world. Comments shared on Downdetector.com indicates that Signal was down for users from India, US, Germany, New Zealand, Netherlands, Australia, Brazil and many other countries.

"Down in Midwest USA. Signal was started by people connected to which secret 3-letter organization? (Look it up) Yep, that's right! An app disguised a privacy app to trick you into sharing more private information than you would with another messaging app," a user said. "I think Signal is having a rough day. Good luck, Team Signal. I'm sure you'll have it sorted out in a snap," said another. The encrypted messaging service has climbed to the top spot in the free apps category of the App Store in multiple countries, including India. (IANS/ MBI)
