During the STS-68 mission (September 30-October 11, 1994), the crewmembers of Space Shuttle Endeavour used a 70 mm camera to photograph Klyuchevskaya Sopka (also known as Kliuchevskoi), a stratovolcano, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. The eruption was new when this photo was taken. It was photographed from 115 nautical miles (213 kilometers) above Earth.

The sea ice cover blanketing the Arctic Ocean and nearby seas thickens and expands during the fall and winter each year. It reaches its maximum yearly extent in February or March. This year (2018), on March 17, the Arctic sea ice cover peaked at only 5.59 million square miles (14,478,033.54 km2), the 2nd lowest max on record. It is only about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached in last year, on March 7, 2017.

This week, NASA’s Mars Curiosity Rover celebrated its 2,000th Martian day (or Sol) on the Red Planet. The nuclear-powered rover was launched from Cape Canaveral on November 26, 2011, and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012. A Mars day is slightly longer than a day here on Earth: a sidereal day is 24 hours, 37 minutes, and 22 seconds (on Earth, it is 23 hours, 56 minutes and 4.1 seconds) and a solar day is 24 hours, 39 minutes, and 35 seconds (on Earth, 24 hours).

Will we ever visit other stars? Maybe, in the distant future, if humans won’t become extinct, our grand grand … (insert a hundred or a thousand grands here) children can stand on an exoplanet’s surface someday. But, we don’t have to wait. NASA has opened a new web page, an “Exoplanet Travel Bureau”, and we can, at least, see the artists’ imaginations of what an exoplanet surface look like, based on available data. NASA warns, there are no actual images of the exoplanets, obviously. With interactive 3D images, it is still an exciting experience.

NASA APOD (Astronomy Picture of the Day) published an amazing video showing a rotating Moon. In fact, no one sees the Moon rotate like this. We see only one side of the moon, because the Moon is tidally locked to Earth. But, thanks to modern digital technology combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high-resolution virtual Moon rotation movie has been composed.

A great short science fiction film, “Others Will Follow”, created and directed by Andrew Finch and published on Vimeo, tells the story of a manned Mars mission. An accident occurs and the spacecraft breaks apart, the last survivor (we don’t see what happens to the rest of the crew, but presumably they have died) manages to send an inspirational message back to Earth. A must-watch.

According to a new study, microbes like those found in Earth’s deep ocean could potentially thrive in the underground ocean of Saturn’s icy moon Enceladus. Both molecular hydrogen (H2) and methane (CH4) already have been detected in the plume. Researchers have shown that Methanothermococcus okinawensis, a methanogenic archaeon first isolated from a deep-sea hydrothermal vent on the western Pacific Ocean, can produce methane under conditions known to exist on Enceladus.

On February 6, 2018, SpaceX successfully tested Falcon Heavy, the most powerful rocket that the American company ever built. When lifted off, it became also the most powerful operational rocket in the world. Powerful rockets like Falcon Heavy may one day carry humans to the Moon or Mars. But there might be even more important use of powerful rockets like SpaceX’ Falcon Heavy and BFR, Blue Origin’s New Glenn or NASA’s SLS: asteroid mining.

NASA’s asteroid-sampling OSIRIS-REx spacecraft captured a new Earth-Moon image on Jan. 17, 2018, from a distance of 39.5 million miles (63.6 million kilometers). Spacecraft used its NavCam1 imager to take this photo, as part of an engineering test. In the image, The Earth and the moon are just two bright dots against the vastness of black space – which reminds us Carl Sagan’s famous speech: “That’s here. That’s home. That’s us.”

As a result of the global warming, the seas warm and ice melts. Naturally, Earth’s oceans have risen steadily – or at least, it was thought so. According to a new study based on 25 years of NASA and European satellite data, rather than increasing steadily, global sea level rise has been accelerating in recent decades. If this trend continues, by the year 2100, sea level rise will be around 65 cm (25.6 in), twice as big as previously thought. This is more than enough to cause significant problems for coastal cities.
