The head of Russia’s space agency said Friday that two astronauts who survived the midair failure of a Russian rocket would fly again and would provisionally travel to the International Space Station (ISS) in spring of next year.

Dmitry Rogozin, the head of Russian space agency Roscosmos, was speaking a day after Russian cosmonaut Alexei Ovchinin and American Nick Hague made a dramatic emergency landing in Kazakhstan after the failure of the Soyuz rocket carrying them to the orbital ISS.

Rogozin Friday posted a picture on Twitter of himself next to the two astronauts and said they had now arrived in Moscow. Both men escaped unscathed and feel fine, Roscosmos has said.

The mishap occurred as the first and second stages of a Russian rocket separated shortly after the launch from Kazakhstan’s Soviet-era cosmodrome of Baikonur.

Thursday’s accident was the first serious launch problem experienced by a manned Soyuz space mission since 1983, when a crew narrowly escaped before a launch pad explosion.

The Interfax news agency Friday cited a source familiar with the Russian investigation as saying that a faulty valve had caused the first stage of the Soyuz-FG rocket to malfunction even though the valve had been properly checked before take-off.

NASA has relied on Russian rockets to ferry astronauts to the space station since the United States retired its Space Shuttle program in 2011, although the agency has announced plans for a test flight carrying two astronauts on a SpaceX commercial rocket next April.

Space is an area of cooperation between the United States and Russia at a time of fraught relations. Asked about the mishap, President Donald Trump told reporters at the White House he was “not worried” that American astronauts have to rely on Russia to get into space.

Moscow has suspended all manned space launches, while Rogozin has ordered a state commission to investigate what went wrong. Russia’s Investigative Committee has also opened a criminal investigation into the matter.

Habitability Of Surrounding Planets Affected By Super Flares Of Red Dwarfs: NASA

Red dwarfs -- especially young red dwarfs -- are active stars, producing flares blast out energy

Using NASA’s Hubble Space Telescope, astronomers have found that violent outbursts, or superflares, from red dwarf stars could affect the habitability of any planets orbiting it.

Young low-mass stars flare much more frequently and more energetically than old stars and middle-age stars like our Sun, the findings of the study published in the Astrophysical Journal showed.

The findings are based on observations of the flare frequency of 12 red dwarfs.

Hubble is observing such stars through a large programme called HAZMAT — Habitable Zones and M dwarf Activity across Time.

“M dwarf” is the astronomical term for a red dwarf star — the smallest, most abundant and longest-living type of star in our galaxy.

The HAZMAT programme is an ultraviolet survey of red dwarfs at three different ages — young, intermediate, and old.

“The goal of the HAZMAT programme is to help understand the habitability of planets around low-mass stars,” explained the programme’s principal investigator, Evgenya Shkolnik from Arizona State University.

“These low-mass stars are critically important in understanding planetary atmospheres,” Shkolnik added.

Stellar flares from red dwarfs are particularly bright in ultraviolet wavelengths, compared with Sun-like stars.

Hubble’s ultraviolet sensitivity makes the telescope very valuable for observing these flares.

The flares are believed to be powered by intense magnetic fields that get tangled by the roiling motions of the stellar atmosphere.

When the tangling gets too intense, the fields break and reconnect, unleashing tremendous amounts of energy.

The team found that the flares from the youngest red dwarfs they surveyed — just about 40 million years old — are 100 to 1,000 times more energetic than when the stars are older.

This younger age is when terrestrial planets are forming around their stars.

About three-quarters of the stars in our Milky Way galaxy are red dwarfs. Most of the galaxy’s “habitable-zone” planets — planets orbiting their stars at a distance where temperatures are moderate enough for liquid water to exist on their surface — orbit red dwarfs.

In fact, the nearest star to our Sun, a red dwarf named Proxima Centauri, has an Earth-size planet in its habitable zone.

However, red dwarfs — especially young red dwarfs — are active stars, producing flares that could blast out so much energy that it disrupts and possibly strips off the atmospheres of these fledgling planets. (IANS)
